A light emitting diode （發(fā)光二極管）, or L．E．D．, is a device that shines when electricity passes through it．But it works differently than traditional kinds of light bulbs．Light emitting diodes use less energy and last much longer than bulbs with a filament （燈絲） inside．L．E．                               D．’s are also cooler to the touch, and shine a lot brighter than they used to．  
Red L．E．D．’s have long been used as signal lights on electronic equipment．But now light emitting diodes also come in blue and other colors．Colored L．E．D．’s are used to show images on everything from wireless phones to huge video signs．And white L．E．D．’s are being used increasingly to replace traditional lighting systems．  
But all these require electricity．In poor countries, people often burn fuel to produce light．But the smoke can make people sick．So an electrical engineering professor from Canada started a project to produce L．E．       D．lighting systems for the developing world．These lights are powered by batteries that can be recharged with energy from the sun．The batteries can also be charged through other ways, such as wind power and water power．
Professor David Irvine-Halliday tells the story of how he got the idea．In 1997, while climbing in the Annapurna mountains in Nepal, he saw a small school．All the children were outside．He looked through a window and saw that inside the school was dark．The school had a sign that read: "We have no teachers．If you want to stay and teach for a few days, we would be very pleased．" Professor Irvine-Halliday says that experience had a big effect on him．Back at the University of Calgary, he was on the Internet one day．He saw a company in Japan selling bright white L．E．                           D．’s．So he built a light with some．This is how he began the Light Up the World Foundation．
48．Compared with traditional kinds of light bulbs, L．E．D．’S________．
A．waste a lot of energy                    B．need shorter time to make
C．shine much brighter                 D．a(chǎn)re warmer to touch
49．According to the passage, we know that L．E．D．’s________．
A．will replace all the lights            B．will be more and more popular
C．will be only colored ones               D．will be only used in developing countries
50．According to the passage, we can infer that the purpose of the Light Up the World Foundation is to________．
A．develop L．E．D．lighting system for the developing world                   
B．sell bright white L．E．D．’s
C．collect money for developing countries                                        
D．earn money by selling L．E．D．’s

Unless we spend money to spot and prevent asteroids (小行星) now, one might crash into Earth and destroy life as we know it, say some scientists.
Asteroids are bigger versions of the meteoroids (流星) that race across the night sky. Most orbit the sun far from Earth and don’t threaten us. But there are also thousands whose orbits put them on a collision course with Earth.
Buy $50 million worth of new telescopes right now. Then spend $100 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one, the scientists say, we’ll have a way to change its course.
Some scientists favor pushing asteroids off course with nuclear weapons. But the cost wouldn’t be cheap.
Is it worth it? Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500,000 years. Sounds pretty rare-but if one did fall, it would be the end of the world. If we don’t take care of these big asteroids, they’ll take care of us,” says one scientist. “It’s that simple.”
The cure, though, might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth? “ The world has less to fear from doomsday (毀滅性的) rocks than from a great nuclear fleet set against them,” said a New York Times article.
66. What does the passage say about asteroids and meteoroids?
A.They are heavenly bodies different in composition.
B. They are heavenly bodies similar in nature.
C. There are more asteroids than meteoroids.
D. Asteroids are more mysterious than meteoroids.
67. What do scientists say about the collision of an asteroid with Earth?
A. It is very unlikely but the danger exists.
B. Such a collision might occur once every 25 years.
C. Collisions of smaller asteroids with Earth occur more often than expected.
D. It’s still too early to say whether such a collision might occur.
68. What do people think of the suggestion of using nuclear weapons to alter the course of asteroids?
A. It sounds practical but it may not solve the problem.
B. It may create more problems than it might solve.
C. It is a waste of money because a collision of asteroids with Earth is very unlikely.
D. Further research should be done before it is proved applicable.
69. We can conclude from the passage that ________
A. while pushing asteroids off course nuclear weapons would destroy the world.
B. asteroids racing across the night sky are likely to hit Earth in the near future.
C. the worry about asteroids can be left to future generations since it is unlikely to happen in our lifetime
D. workable solutions still have to be found to prevent a collision of asteroids with Earth.
70. Which of the following best describes the author’s tone in this passage?
A. Optimistic          B. Critical         C. Objective         D. Arbitrary

China has now mapped out plans for its next four launches in the Shenzhou program on the next flight. But one conclusion seems to have escaped most reports in the aerospace media. The flight of Shenzhou 7 could be timed to coincide with the Beijing Olympics. Plans for the 2008 Summer Olympics call for the events to be held between the 8th and 24th of August. It's reasonable to expect that China will use the event to promote its achievements before the world, and human spaceflight is China's most significant recent breakthrough.
Shenzhou 7, China's next manned space mission, was originally advertised for 2007. This fit into the pattern of staging a two-year gap between crewed Shenzhou missions, which have previously launched in 2003 and 2005. But Chinese media statements have recently amended this to 2008. Chinese media have reported that while the overall program is going well, more time is needed to work on the spacesuit that will be used on this flight to stage China's first spacewalk. It's possible that Chinese engineers want to make best preparations for this complex mission.
China could intend to carry out the mission of Shenzhou 7 just as media attention is focused on the lead-up to the Olympics. The crew of the flight, and possibly China's other flown astronauts, could then take part in the opening ceremony. China has previously feted her space travellers in great celebrations, such as the Hong Kong event that saw Yang Liwei singing with actor Jacky Chan.
China has also suggested that the activity will be carried out by a single astronaut, and has indicated that half an hour is a rough estimate of the planned time for the spacewalk. China is apparently following suit, probably for the same reasons of conservative mission planning and safety.
41. From the first paragraph we can infer that ________.
A. China hasn’t made its plan for the Beijing Olympics
B. The new Shenzhou program are known to all the reporters
C. China has planned to send up Shenzhou 7 in 2008
D. Beijing Olympics will be held during the flight of Shenzhou 7
42. China has decided to carry out its human spaceflight in 2008 in order to ______.
A. make the Beijing Olympics more interesting
B. show its great achievements to the world
C. prove that China is a developed country
D. introduce its science and technology to the world
43. Which one of the following is WRONG according to this passage?
A. China sent its first manned spacecraft in October of 2003.
B. Chinese engineers want to make more preparations for Shenzhou 7.
C. The spacesuit for the flight of Shenzhou 7 hasn’t been prepared well.
D. Two Chinese astronauts walked in space in 2003.
44. The underlined word “amended” in the passage has a similar meaning to ______.
A. improve            B. change                     C. expect               D. decide
45. What would be the best title for this passage?
A. The Beijing Olympics.                        B. The Shenzhou Olympics.
C. China’s Shenzhou Program.                 D. Spacewalk in 2008.

Technology has utterly transformed our ability to communicate with each other. Linking to each other both literally and figuratively, many of us connect through cell phones, email, instant messaging, blogs, and networking web sites, yet we may be less connected to each other than we think.
According to a study, Americans are becoming increasingly socially isolated. The study reveals, for example, that one quarter of Americans say that they have no one to discuss important personal issues with, and that the number of close friends that American have has dropped from three to two. Meanwhile, the Boston Globe reports that this spreading isolation is experienced more sharply among those with less education, people of color, and older Americans. Unsurprisingly, those who are young, white, and well educated tend to have stronger social networks.
From my own experience I have to say that I’ve never felt more connected, thanks to a web of friends, family, and colleagues. One of my closest friends is someone I met through an online discussion group who lives hundreds of miles away from me. We have met face-to-face only twice, yet our regular electronic correspondence and cell phone calls sustain our close friendship. And, speaking of blogging, my blog has introduced me to people I would never have met otherwise and has led to enduring and important friendships.
On the other hand, I recently saw a scene unfold that proved to me how deeply disconnected we as Americans have become. I had just wrapped up a presentation on mediation at a family therapy(治療) center. As I was leaving, I noticed a mother and her teenage son who had just completed their session with their family therapist(臨床醫(yī)學(xué)家). After making their next appointment, they both took out their cell phones, placed calls, and began loud conversations with whoever was on the other end. I walked out behind them to the parking lot to my car. They both jumped into their SUV, and, as I saw them drive off, they were still talking on their cell phones.
But, alas, not to each other.
51. What does the passage lead you to believe?
A. Americans are more socially connected today.
B. Americans are more socially isolated today.
C. Technology plays a bigger role in American society.
D. Americans don’t make good use of technology.
52. Which of the following has nothing to do with the isolation among Americans?
A. Age.              B. Education.                C. Skin color.               D. Sex.
53. The author himself _______.
A. has a wider range of friends because of technology
B. has failed to take advantage of technology
C. can only find true friendship through the Internet
D. can’t make true friends in actual life
54. What is true about the mother and son in the passage?
A. They came for therapy in the same car.
B. They were quite close to each other.
C. There was not much communication between them.
D. They preferred talking to each other on cell phones.
55. The author probably feels ________ with the mother and son.
A. puzzled         B. disappointed       C. amused                 D. surprised

Science。And technology students in China and the US  have a1ong way to go before they call develop a deep understanding of scientific reasoning,researchers have found．
As part of a research to compare science education in China and the US，LeiBao,a professor
from the Departmenr of Physics of the Ohio State University, gave 5,760；freshmen in three US and four Chinese univeristies two tests to evaluate content knowledge  and another to assess scientific reasoning
Though Chinese students did better than their US counterparts in the first two tests that
Emphasized on learning facts,both groups “scored relatively poorly”on the third test,designed to
Assess their ability ot systmatically explore a problem , the results showed.
Lei Bao said that the finding challenges conventional wisdom，which holds that teaching
science facts will improve students’reasoning ability．“Our study shows that ,contrary to what many  people would expect，even when students are thoroughly taught the facts，they don’t necessarily develop the reasoning skills they need io succeed．’’IBao said：‘“Because students need both knowledge and reasoning,we need to explore teaching methods that target both．”
‘The current education systems and asessment of China and the US do not emphasize on deep understanding of scientific reasoning in the disciplines of science；technology,engineering and mathematics(STEM)，the study concluded．
Bao explained that reasoning is good skill for everyone topossess-not just scientists and
engineers：The general public also need good reasoning skills in order to correctly interpret
scientific findings and think rationally．STEM students need to excael at scientific reasoning in order to handle open-ended real-world tasks in their future careers in science and engineering．
How to boost scientific reasoning?The study suggests that educators must go beyond teaching science facts if they hope to boost students’reasoning ability．Bao points to inquiry-based leaming.where students work in groups，question teachers and design their owu investigations．This teaching technique is growing in popularity worldwide．
67．According to the research，we know that              
A．Chinese students and their US counterparts did poorly in the first two tests
B．Chinese students did beaer than their US counterparts in alI the three tests
C．Chinese students did beaer than their US counterparts in the first two tests    ‘
D．US students did beaer than their Chinese counterparts in the third test
68．The conventional wisdom holds that           ．
A．the more facts~tudents are taught，the more reasoning skills they will acquire
B．the general public also need reasoning skills to interpret scientific findings
C．to boost students’reasoning ability,educators must explore teaching methods
D．the current education Systems are harmful to improve students’reasoning ability
69．Based on the study,what will be done to improve students’reasoning ability?
A．To improve teaching techniques．        B．To better students’learning conditions．
C．To teach students more science facts．    D．To offer students more tests．
70．The underlined phrase“excel at”in Paragraph 6 probably means       ．
A．be worse at    B．be beaer at    C．be enthusiastic about D．be inferior to
71．Which of the following is correct according to the passage?
A．Little needs to be done to develop students’reasoning ability in the US．
B．Only scientists and engineers need reasoning abilities．
C．Two tests were carried out to evaluate students’scientific reasoning．
D．Inquiry-based learning is a good way to boost students’reasoning ability．

New York was very proud of its electric trolleys(無(wú)軌電車) at the turn of the century. They were the latest way to get around. But Mary Anderson, who visited New York from her native Birmingham, Alabama, 1902, did not like them at all. She thought they were not safe.
It was not that the drivers were bad. It was the windshields (擋風(fēng)玻璃). In those days, drivers rubbed their windshields with damp tobacco. This was supposed to help off rain and snow. But it did not work too well. Anderson watched as the trolley drivers struggled to see out of their windshields, and came up with an idea.
Back in Alabama, Anderson made the first windshield wiper by fixing handle （把手）to a rubber blade (片). This, in turn, was fixed to the windshield. The drivers had to turn the handle back and forth by hand to make the blade wipe off the rain. But it worked. And travel in bad weather was made a little safer for everyone.
36.Which of the following best gives the main idea of this passage?
A.How Mary Anderson visited New York?
B.How drivers cleaned their windshields?
C.How the first windshield wiper came into being?
D.How windshield wiper was made?
37.Though New Yorkers had great pride in electric trolleys, Mary disliked them because she thought ______________.
A. they were dangerous            B.they kept off rain and snow
C.their windshields were not good    D.their drivers were inexperienced
38.To stop rain and snow coming on the windshields, a trolley driver had to _______.
A. work hard             B.see out of them clearly 
C.struggle in the trolleys     D.use damp tobacco to clean them
39.Which of the following is NOT true according to the passage?
The windshield wiper helped keep off the rain.
The windshield wiper was turned by the driver.
The rubber blade was fixed to the windshield.
The windshield wiper was made in Alabama.

In late March, Southwest University became the first school in China to open a 24-hour hotline providing suicide-prevention counseling．
College suicide is a heart-breaking and argumentative topic．Chinese college students have long been the focus of public attention: their youth, education and, most importantly, bright futures make them the envy of society．
However, in recent years, we've read more reports of student suicides．Perhaps that's simply because of society's attention with youth．But it could also signify the increasing troubled mental state of college students．
Many studies have sought to find out the causes of student suicides．Not surprisingly, the top factors usually include psychological and physical sickness, emotional trouble and peer pressure．Despair about their futures is also quickly becoming a leading factor: many students say they feel hopeless and confused about the direction of their careers in a crowded job market．
Thankfully, more and more universities and colleges are providing counseling services to address students' mental and psychological problems．These at least offer some comfort to students facing tough job prospects and personal difficulties．
From appointing in-house student counselors to setting up hotlines and recruiting students to help their troubled peers, many universities are making efforts to fight student depression．There is no denying that much remains to be done, but such efforts are already working, helping students and saving lives．
However, the most important front in this battle lies with the students themselves．Whatever efforts school officials make, it is up to students to realize their problems and ask for help．Unfortunately, many students considering suicide refuse to seek help．By shutting themselves away, they can easily fall into vicious cycles (惡性循環(huán)), becoming even more easily hurt to personal
difficulties and the pressures of the outside world．
While establishing better on-campus psychological education and outreach programs as a step forward, students themselves must actively reach out for help．These dangers are a reality for every
student, not only those who feel confused and depressed．
63．Why are there so many students that commit suicide?
A．Because of psychological and physical sickness．?
B．Because they feel hopeless and confused about their future．
C．Because of the emotional trouble．
D．All of the above．
64．According to the article, all of the following are right except ____．
A．No university in China had a whole day hotline about suicide-prevention before March．
B．Many people envy the college students their bright futures．
C．The students who feel confused and depressed may need psychological education．
D．The problems of student suicides indicate the increasing troubled mental state of youths.
65．The key to avoid student suicides is that ____．
A．parents communicate with their children and understand them
B．colleges and universities offer more help to students
C．students themselves realize their problems and seek help from others
D．friends give more comfort and show more understanding to the problem students
66．Which of the following can be the main idea for this article?
A．Help is at hand for suicidal students．
B．More college students commit suicide．
C．How can students avoid committing suicide?
D．Why do college students feel depressed?

Good news for game lovers― a tank game has come out recently. In this game you are in a tank and the screen shows your view of the landscape outside. You gain points by shooting enemy tanks, supertanks, missiles (導(dǎo)彈) and flying saucers（飛碟）.
Expert players can gain scores of around 150,000 points at this game. To get a high score you have to destroy twenty tanks as quickly as possible. After this, the supertanks, missiles and flying saucers appear. These are worth far more points than the ordinary tanks. However, the number of tanks you have to destroy before the supertanks appear varies on different machines.
Try to get close to an enemy tank from the side or the back, so it cannot shoot at you. Then, when you get close, turn to face it, line it up in your sights and fire before it turns to shoot at you. If you miss or are too slow, quickly escape by moving out of the enemy's line of fire. You can then move around the enemy and come in from another side.
When a supertank appears, try to destroy it as quickly as possible. Then wait safely behind an obstacle（障礙物）for a missile or flying saucer. The cubes are useful objects to hide behind as you can fire over them without exposing yourself to danger. The missiles will fly straight at you, but they are difficult to hit, so do not shoot at them until they are quite close. The saucers are much easier to hit, but do not follow them as you will be open to attack from enemy tanks. 
60. This passage is an / a ______ about a game.
A. instruction    B. liberation        C. tradition     D. construction
61. If you hide behind the cubes during an attack, which of the following may not happen?
A. Avoiding being exposed to danger     B. Destroying a missile
C. Firing over missiles or flying saucers   D. Being hit by a missile
62. If you can destroy a supertank, missile or flying saucer, you will get_____.
A. many more points        B. a machine to play with
C. an ordinary tank         D. nothing
63. From the last sentence we can see that you are likely to be attacked by tanks if you_____.
A. hit a flying saucer            B. run after a flying saucer
C. fire straight at a missile        D. shoot at enemy tanks

Lateral thinking（迂回思維），first described by Edward de Bono in 1967，is just a few years older than Edward’s son．You might imagine that Caspar was raised to be an adventurous thinker，but the de Bono was so famous，Casspar’s parents worried that any time he would say something bright at school，his teachers might ask，“Where do you get that idea from？”
“We had to be careful and not overdo it．”Edward admits．Now Caspar is at Oxford-which once looked unlikely because he is also slightly dyslexic（誦讀困難）．In fact，when he was applying to Oxford，none of his school teachers thought he had a chance．“So then we did several thinking sessions,”his father says，“using my techniques and，when he went up for the exam，he did extremely well．”Soon after，Edward de Bone decided to write his latest book，“Teach Your Child How to Think”，in which he transforms the thinking skills he developed for brain-storming businessmen into informal exercises for parents and children to share．
Thinking is traditionally regarded as something executed in a logical sequence，and everybody knows that children aren’t very logical．So isn’t it an uphill battle，trying to teach them to think？“You know，”Edward de Bono says，“if you examine people’s thinking，it is quite unusual to find faults of logic．But the faults of perception are huge！Often we think ineffectively because we take too limited a view．”
“Teach Your Child How to Think”offers lessons in perception improvement，of clearly seeing the implications of something you are saying and of exploring the alternatives．
60．What is TRUE about Caspar？
A．He is Edward’s son．   B．He is an adventurous thinker．
C．He first described lateral thinking．      D．He is often scolded by his teacher．
61．It can be inferred from paragraph 2 that Edward        .
A．was likely to improve children’s logic with his book
B．gave a description of lateral thinking several years after his son was born
C．was prompted to study lateral thinking because his son was slightly dyslexic
D．once taught businessmen how to think before he wrote for parents and chikdren
62．According to Paragraph 3，which of the following statements expresses Edward de Bone’s view？
A．Everybody knows that children aren’t very logical．
B．It is an uphill battle trying to teach children to think．
C．We often think ineffectively because we take too limited a view．
D．Thinking is traditionally regarded as something executed in a logical sequence．
63．Lateral thinking refers to the following EXCEPT        ．
A．improving one’s logic in thinking
B．improving one’s perception in thinking
C．seeing the implications of what you are saying
D．exploring the alternatives for what you are saying

The ocean bottom, a region nearly 2．5 times greater than the total land area of the Earth, is even today largely unexplored．Until about a century ago, the deep-ocean floor was completely inaccessible and hidden beneath waters averaging over 3,600 meters deep．Totally without light and subjected to intense pressures hundreds of times greater than at the Earth’s surface, the deep-ocean bottom is a strangeenvironment to humans, in some ways as forbidding and remote as the outer space．
Although researchers have taken samples of deep-ocean rocks for over a century, the first detailed global study of the ocean bottom did not actually start until 1969, with the beginning of the National Science Foundation’s Deep Sea Drilling Project(DSDP)．Using techniques first developed for the offshore oil and gas industry, the DSDP’ s drill ship, the Glomar Challenger, was able to maintain a steady position on the ocean’s surface and drill in very deep waters, taking samples of  rock from the ocean floor．
The Glomar Challenger completed 96 voyages in a 15-year research program that ended in November 1983．During this time, it sailed 600,000 kilometers and took almost 20,000 samples of rocks aroun d the world．Those samples have allowed geologists to reconstruct what the planet looked like hundreds of millions of years ago and to make out what it will probably look like millions of years in the fu ture, Today, largely on the strength of evidence gathered during the Glomar Challenger’ s voyages, nearly all earth scientists agree on the theories of plate tectonics （構(gòu)造學(xué)）and continental drift that explain many of the geological processes．
The samples of rocks drilled by the Glomar Challenger have also provided a climatic record stretching back hundreds of millions of years．The information of past climatic change can be used to predict future climates．
68．What does the underlined word “inaccessible” in line 3 means?
A．unrecognizable     B．unreachable       C．unusable        D．unreasonable
69．Why does the author mention “outer space” in the first paragraph?
A．The Earth’s climate millions of years ago was similar to that in outer space．
B．It is similar to the ocean floor in being strange to the humans．
C．Rock formations in outer space are similar to those found on the ocean floor
D．Techniques used by scientists to explore outer space were similar to those used in ocean exploration
70．Which of the following is true of the Glomar Challenger?
A．It is a type of submarine．               B．It is an ongoing project．
C．It has gone on over 100 voyages．        D．It made its first DSDP voyage in 1968．
71．Which of the following is NOT mentioned in the passage as being a result of the Deep sea Drilling Project?
A．Geologists were able to determine the Earth’s appearance millions of years ago．
B．Two geological theories became more widely accepted by scientists．
C．Geologists observed forms of life never before seen
D．Information was revealed about the Earth’s past climatic changes．
