BEIJING - By the end of 2011 China-made supercomputers will say goodbye to foreign microchips（微芯片） and start using their own "Chinese core(核心)", according to one of the country's leading scientists, Hu Weiwu.
Hu told reporters on Saturday that the "Dawning 6000" supercomputer, developed by the Institute of Computing Technology of CAS and the Dawning Information Industry Company (DIIC), will adopt Loongson microchips for the first time as its core parts. It will have a computing speed of more than 1,000 trillion operations a second.
Making supercomputers with Chinese microchips is one of the nation's major science and technology projects. Three organizations - the Institute of Computing Technology of CAS, Jiangnan Institute of Computing Technology and the National University of Defense Technology (NUDT) - have their own supercomputer projects.
According to their schedules, all three institutions will need to meet the target of using domestically（國內(nèi)的） developed microchips by the end of this year. Hu said the new supercomputer will use fewer than 10,000 Loongson microchips, and will also be more energy-efficient.
Tianhe-1A, developed by NUDT in Hunan's provincial capital Changsha, is the fastest supercomputer in the world. However, Tianhe-1A largely runs on 14,336 CPUs made by Intel, and 7,186 GPUs (processing units) from Nvidia, two US chip-makers.
Hu said there will be difficulties ahead as there is little affiliated equipment specially developed for these supercomputers. "We have enough supercomputers in China but still can't make full use of them," He said.
Hu added that although the China-made CPUs have improved since they were first produced in 2002, they have a long way to go to compete with US chip-makers such as Intel.

(2013·高考新課標全國卷Ⅰ，B)The baby is just one day old and has not yet left hospital.She is quiet but alert (警覺)．Twenty centimeters from her face researchers have placed a white card with two black spots on it.She stares at it carefully.A researcher removes the card and replaces it by another，this time with the spots differently spaced.As the cards change from one to the other，her gaze(凝視) starts to lose its focus—until a third，with three black spots，is presented.Her gaze returns：she looks at it for twice as long as she did at the previous card.Can she tell that the number two is different from three，just 24 hours after coming into the world?
Or do newborns simply prefer more to fewer? The same experiment，but with three spots shown before two，shows the same return of interest when the number of spots changes.Perhaps it is just the newness? When slightly older babies were shown cards with pictures of objects (a comb，a key，an orange and so on)，changing the number of objects had an effect separate from changing the objects themselves.Could it be the pattern that two things make，as opposed to three? No again.Babies paid more attention to squares moving randomly on a screen when their number changed from two to three，or three to two.The effect even crosses between senses.Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two；likewise (同樣地) when the researchers started with drumbeats and moved to spots.
小題1:The experiment described in Paragraph 1 is related to the baby’s________.
A．sense of hearing B．sense of sight
C．sense of touch D．sense of smell
小題2:Babies are sensitive to the change in________.
A．the size of cards B．the colour of pictures
C．the shape of patterns D．the number of objects
小題3:Why did the researchers test the babies with drumbeats?
A．To reduce the difficulty of the experiment.
B．To see how babies recognize sounds.
C．To carry their experiment further.
D．To keep the babies’ interest.
小題4:Where does this text probably come from?
A．Science fiction.
B．Children’s literature.
C．An advertisement.
D．A science report.

The first flights of the new airlines that will take tourists into space are ready to take off in 2012, and getting a seat on one is not all that different from booking a trip someplace on Earth. You can sign up on the website of, say, Virgin Galactic，the most well­known of the new space tourism companies, or go to an approved travel agency and put down a large deposit. Soon you will be able to buy travel insurance，just as you can for any other vacation.
Until now，space tourism has been limited to the ultrawealthy. Just seven people have paid tens of millions of dollars each for a trip to the International Space Station aboard a Russian rocket.
But that could change this year, when Virgin Galactic intends to start offering flights just beyond the space barrier on a rocket ship it has built, featuring five minutes of weightlessness during a two­and­a­half­hour tour. At $ 200,000 a seat, this will open the final frontier to far more people.
At least two other specialty airlines have jumped in as well, taking reservations and deposits for future space flights.Allianz, the big insurer, will introduce an insurance product in 2012, lending space tourism the trappings of the regular travel industry.
“Just to be able to sell space travel as a regular part of your business, really, just how cool is that？” said Lynda Turley Garrett, president of Alpine Travel of Saratoga, Calif.，who is one of 58 accredited space agents for Virgin Galactic in the United States.
In five years，Ms.Garrett has sold three seats. But she expects that to change once passengers start going up and coming down to tell their friends. “By 2017，it'll be just like scheduling a flight to L．A.，” Ms.Garrett predicted.
小題1:If you want to book a flight to space in 2012, you can________.
A．go to any travel agency
B．telephone Virgin Galactic
C．pay a visit to Allianz
D．sign up on the website of Virgin Galactic
小題2:From Paragraph 2 we can know that ________.
A．only the extremely rich people can afford the space trip
B．seven people have paid tens of millions of dollars for a space trip
C．Russia is the first country to build the space station
D．ordinary people are not allowed to take space tour
小題3:Which of the following is true of Virgin Galactic?
A．It is one of the approved space agencies.
B．It is a famous space tourism company.
C．It sells insurance products to space tourists.
D．Its rocket has carried space passengers successfully.
小題4:What does the underlined word “trappings” in Paragraph 4 probably refer to?
A．Standard uniforms.
B．Traditional decorations.
C．Symbolic signs.
D．Personal belongings.
小題5:What does Ms. Garrett think of the future space travel?
A．Common.　B．Changeable.
C．Flexible.　D．Reasonable.

There are some new drivers going back to school. Teens who have recently gotten their driver's licenses may be taking the wheel to school this fall. However, parents fear when their teen starts driving. And it turns out that such parental fears are justified, so it's worth reviewing how to keep your teen safe while he or she is behind the wheel.
Motor vehicle crashes are the leading cause of death among US teens. Drivers 16 to 19 years old are at the greatest risk of crashes. In fact, their risk is 4 times greater than that of older drivers. The teens at the greatest risk are those who are male, those carrying other teenage passengers in the car, and those still in their first year of driving. Nearly 50 percent of teen deaths related to automobile crashes happen on Fridays, Saturdays, or Sundays between the hours of 3 pm and midnight.
Why are teens at higher risk of motor vehicle crashes?
Development. Teens haven't completely matured mentally and have greater risk­taking behaviors, possibly because they tend to underestimate the risk associated with a particular behavior. Teens also have a greater tendency to speed and to drive too close to the cars in front of them.
No seatbelts. Teens have the lowest rate of seatbelt use among all driving groups.
Alcohol. A least 25 percent of motor vehicle deaths in teens are related to drinking alcohol.
Technological distractions(分散注意力的事)．Cellphones，texting，MP3 players，and the like can all distract drivers greatly—and who more than teenagers?
Be aware of your teen's driving practices and discuss safe driving habits when opportunities present themselves. Check out the applications and devices now available for restricting your teen's use of technology while driving. Some applications alert you to the danger when your teen is texting while the vehicle is moving. Another device blocks incoming and outgoing texts when the car is running—incoming messages get an automatic reply (eg. “I'm driving right now”), and phone calls go directly to voicemail. You can also get notifications if your teen tries to shut off the program. There are also GPS programs that let you know your new driver's whereabouts at all times. All in all, you can't be too cautious when teaching your teen how to be safe on the road.
小題1:What factor is least related to the teen drivers' high risks of crashes?
A．Drivers' age.B．Passengers' sex.
C．Driving experience.D．Driving time.
小題2:Teens probably turn away their attention from driving when they are ________.
A．using no seatbeltsB．drinking water
C．carrying passengersD．a(chǎn)nswering cellphones
小題3:According to the passage, which should be prevented during teens' driving?
A．Texting.B．GPS programs.
C．Automated replies.D．Voicemail.
小題4:The author writes the last paragraph in order to ________.
A．offer parents practical suggestions
B．summarize teens' driving practices
C．a(chǎn)dvocate different driving habits
D．set an example for the teens

The weather predictions for Asia in 2050 read like a story from a doomsday movie.
Many experts and green groups fear they will come true unless there is a united global effort to hold back greenhouse gas outpouring. In the decades to come, Asia---home to more than half the world’s 63 billion people-will change from one climate extreme to another, with tired farmers battling droughts, floods, disease, food shortages and rising sea levels.
“It’s not a pretty picture,” said Steve Sawyer, climate policy adviser with Greenpeace in Amsterdam. Global warming and changes of weather patterns are already occurring and there is more than enough carbon dioxide and other greenhouse gases in the atmosphere to drive climate change for decades to come.
Already, changes are being felt in Asia but worse is likely to come, Sawyer and top climate bodies say, and could lead to mass migration and widespread human disasters. According to predictions, icebergs will melt faster, some Pacific and Indian Ocean islands will have to evacuate(疏散) or build sea defenses, storms will become more intense and insect and water-borne diseases will move into new areas as the world warms.
All this comes with rising populations and demand for food, water and other resources. Experts say environmental worsening such as deforestation and pollution will probably enlarge the results of climate change.
In what could be a sign of the future, Japan was hit by a record of 10 typhoons and tropical storms this year, while two-thirds of Bangladesh, parts of Nepal and large areas of northeastern India were flooded, affecting 50 million people, destroying livelihoods and making tens of thousands ill.
The year before, a winter cold struck and a summer heat wave killed more than 2,000 people in India.
小題1:This passage is mainly about       .
A．what kind of weather we like best
B．the weather predictions for Asia in the future and the reasons
C．how to improve our environment
D．that the world will not be suitable for us to live in
小題2:In the future the Asian farmers will have to face the following except       .
A．food shortagesB．droughtsC．warsD．floods
小題3:The underlined word “doomsday” may give us the feeling of        .
A．happinessB．sadnessC．peaceD．excitement

Dear Dean,
It is my understanding that this college has received a large donation to be used to improve the quality of life for students: expand the bookstore or add computers to the lab. I strongly argue in favor of the addition of more computers.
We have to think about a greater goal and a more practical way to enhance the quality of life for students. Do we want our college to be known as a place with a great bookstore where you can find CDs and gifts, or as a place where the students can research in their field using the best tools provided by technology?
As a learning institution, this college has the responsibility to offer its students the best technology to help them prepare for their future, since many students will be expected to be familiar with the latest software and other tools when they go on to work.
While they are in college, students find they are expected to use computers. They are asked to create PowerPoint presentations and research many topics on the Internet. Being able to do projects using the computer also gives students the opportunity to find information that without a computer would be much more difficult to find. Since students are competing for good grades, those who have limited access to computers are at a great disadvantage.
If there are more new and faster computers accessible, students will be able to complete their work more efficiently. No more will they have to wait in line, paper and disk in hand, while scanning the room for an empty chair and computer. No longer will they have to sit and wait while an outdated computer struggles to follow their commands.
The more computers are used in society, the more colleges will depend on them as a tool of teaching and learning. Making computers more accessible to students facilitates their learning process by making it much easier and more engaging(專注), and eventually improves their quality of life.
小題1:The purpose of the author in writing the passage is________.
A．to explain why students are in great need of computers
B．to tell us what benefits students can gain from computers
C．to persuade the Dean to purchase more advanced computers
D．to describe the problems caused by lack of computers
小題2:The author mainly wants to tell us in paragraph four that ________.
A．computers are beneficial to students’ academic success
B．computers are the only access to good grades for students
C．students find it convenient to do homework by computers
D．students wish to use more money to buy more computers
小題3:The underlined word “facilitates” can be replaced by________.
A．furthersB．equipsC．predictsD．troubles

A black hole is a place in space where gravity pulls so much that even light cannot get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.
Because no light can get out, people can’t see black holes. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently from other ones.
Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or “staff”, in an object.
Another kind of black hole is called “stellar”(星球黑洞). Its mass can be up to 20 times more than the mass of the sun. There may be many stellar mass black holes in Earth’s galaxy. Earth’s galaxy is called the Milky Way.
The largest black holes are called “supermassive”(超大質(zhì)量黑洞). These black holes have masses that are more than one million suns together. Scientists have found proof that every large galaxy contains a supermassive black hole at its center. The supermassive black hole at the center of the Milky Way galaxy has a mass equal to about four million suns and would fit inside a very large ball that could hold a few million Earths.
Scientists think the smallest black holes formed when the universe began. Stellar black holes are made when the center of a very big star falls in upon itself, or falls apart. When this happens, it exploded part of the star into space. Scientists think supermassive black holes were made at the same time as the galaxy they are in.
A black hole can not be seen because strong gravity pulls all of the light into the middle of the black hole. But scientists can see how the strong gravity affects the stars and gas around the black hole. Scientists can study stars to find out if they are flying around, or orbiting a black hole.
When a black hole and a star are close together, high-energy light is made. This kind of light cannot be seen with human eyes. Scientists use satellites and telescopes in space to see the high-energy light.
小題1:The gravity of a black hole may become so strong that light cannot get out when ____________.
A．the star is going to die
B．special tools are used on it
C．other stars come close to it
D．it is seen from the space telescopes
小題2:According to the passage, which of the following is NOT true?
A．A black hole can be very tiny but extremely heavy.
B．The gravity of a black hole holds all light in its center.
C．Scientists observe high-energy light through their own eyes.
D．Some small black holes came into being as early as the universe.
小題3:The underlined word “galaxy” in Paragraph 5 means __________.
A．a(chǎn) black holeB．the Milky Way
C．a(chǎn) series of starsD．a(chǎn) planet near the earth
小題4:What does the last sentence in Paragraph 5 suggest?
A．Neither the sun nor the earth is as heavy as a black hole.
B．There is a supermassive black hole at the center of the Milky Way.
C．The supermassive black hole had existed before the Milky Way was formed.
D．There is a reason why the large black holes are called “supermassive”.
小題5:The last two paragraph mainly focus on the question of _________.
A．what a black hole is
B．how black holes form
C．how big black holes are
D．how scientists know about black holes

Normally a student must attend a certain number of courses in order to graduate, and each course which he attends gives him a credit which he may count towards a degree. In many American universities the total work for a degree consists of thirty-six courses each lasting for one semester. A typical course consists of three classes per week for fifteen weeks; while attending a university a student will probably attend four or five courses during each semester. Normally a student would expect to take four years attending two semesters each year. It is possible to spread the period of work for the degree over a longer period. It is also possible for a student to move between one university and another during his degree course, though this is not in fact done as a regular practice.
For every course that he follows a student is given a grade, which is recorded. and the record is available for the student to show to potential employers.  All this imposes(增加)  a constant pressure and stress of work, but in spite of this some students still find time for great activity in student affairs. Elections to positions in student organizations arouse much enthusiasm. The effective work of maintaining discipline is usually performed by students who advise the academic authorities. Any student who is thought to have broken the rules, for example, by cheating has to appear before a student court. With the enormous numbers of students. the operation of the system does involve a certain amount of activity. A student who has held one of these positions of authority is much respected and it will be of benefit to him later in his career.
小題1:Normally a student would at least attend __________classes each week.
A．36B．12C．20D．15
小題2:According to the first paragraph an American student is allowed
A．to live in a different university

Many people are aware of the beauty of a solar eclipse (日食), but are surprised to learn that lunar eclipses are often just as impressive. While total solar eclipse lasts only for a few minutes and can be seen only in a small area of a few kilometers, total lunar eclipse can last for several hours and can be seen over much of the planet. In fact, the beauty and stability of lunar eclipses make them a favorite of both amateur and professional photographers.
Lunar eclipses generally occur two or three times a year, and are possible only when the Moon is full. When we see the Moon, we are actually seeing sunlight reflected off the surface of the Moon When the Earth is positioned in between the Moon and the Sun, however, the Earth's shadow falls on the Moon, and a lunar eclipse occurs.
The type of lunar eclipse - total, partial, or penumbral (半影) - that occurs depends both on how much of the Moon passes through the Earth's shadow and through which part of the shadow it passes. A penumbral eclipse occurs when the Moon passes through the Earth's outer shadow. This type of eclipse is brief and frequently goes unobserved by all but astronomers. By contrast, total and partial eclipses occur when all or part, respectively, of the Moon passes through the umbra（本影） shadow of the Earth. These eclipses are quite easy to see and are widely observed.
Unlike solar eclipses, lunar eclipses are safe to watch. Solar radiation that occurs during an eclipse of the Sun can cause a form of burns of one's eyes known as eclipse blindness. In fact, the only way to safely view a solar eclipse is by using specially designed equipment. However, since the Moon's light is reflected sunlight, it is completely safe to watch a lunar eclipse without any special equipment, although a pair of binoculars can certainly help the viewer appreciate the beauty of this phenomenon
小題1:The underlined word "stability " most probably means_______.
A．strengthB．positionC．steadinessD．visibility
小題2:According to the passage, a partial lunar eclipse occurs________.
A．when the Moon passes between the Sun and the Earth
B．when all of the Moon passes through the Earth's umbra shadow
C．when only a part of the Moon passes through the Earth's outer shadow
D．when only a part of the Moon passes through the Earth's umbra shadow
小題3:The passage implies that penumbral eclipses are________.
A．longer-lasting than most solar eclipses
B．more common than partial or full lunar eclipse
C．the result of the shadow cast by the Moon onto the Earth
D．more difficult to observe than other types of lunar eclipse
小題4:According to the passage, it is safe to watch a lunar eclipse, unlike a solar eclipse, because ________.
A．moonlight is less strong than sunlight
B．a(chǎn) lunar eclipse is briefer than a solar eclipse
C．a(chǎn) lunar eclipse lasts much longer than a solar eclipse
D．special equipment can be employed to view a lunar eclipse
