A new study has found that it may be possible to train people to be more intelligent,increasing the brainpower they had at birth.
  Until now,it has been widely assumed that the kind of mental ability that allows us to solve new problems without having any relevant previous experience—what psychologists call fluid intelligence—is innate and cannot be taught(though people can raise their grades on tests of it by practicing).
  But in the new study,researchers describe a method for improving this skill,along with experiments to prove it works.
  The key, researchers found, was carefully structured training in working memory—the kind that allows memorization of a telephone number just long enough to dial it. This type of memory is closely related to fluid intelligence,so the researchers reasoned that improving it might lead to improvements in fluid intelligence.
  First they measured fluid intelligence of volunteers using standard tests. Then they trained each in a complicated memory task—the child’s card game,in which they had to recall a card they saw and heard. During the course, they needed to ignore irrelevant items,monitor ongoing performance,manage two tasks at the same time and connect related items to one another in space and time.
  The four groups experienced a half-hour of training daily for 8,12,17 and 19 days,respectively. To make sure they were not just improving their test-taking skills,the researchers compared them with control groups that took the tests without the training.
  The results, published Monday in The Proceedings of the National Academy of Sciences,were striking. Improvement in the trained groups was a lot greater. Moreover,the longer they trained, the higher their scores were. All performers,from the weakest to the strongest,showed significant improvement.
  “Our results show you can increase your intelligence with proper training.”said Dr Jaeggi, a co-author of the paper.“No one knows how long the gains will last after training stops,”he added,“and the experiment’s design did not allow the researchers to determine whether more training would continue to produce further gains.”
67.The researchers thought the key to improving the intelligence was ______________.
A.memorizing telephone numbers
B.improving working memory
C.training in concentration
D.recalling a card
68.The following aspects of the training help increase intelligence EXCEPT___________.
A.ignoring irrelevant items
B.monitoring ongoing performance
C.managing two tasks at the same time
D.using previous experience
69.When the experiment was conducted,the researchers______________.
A.trained the four groups for the same period of time
B.only made comparisons between the four groups
C.compared the four groups with control groups
D.trained the four groups together
70.By writing the article,the writer intends to ______________.
A.inform the readers of a new study
B.call on people to be trained to increase intelligence
C.prove one’s born brainpower can be improved
D.tell people the improved intelligence will last forever

The marine environment is fascinating to study and work in due to its beauty, richness, and complexity. It covers three quarters of the surface of the Earth, yet we know more detail about the surface of Mars.
In the past, it was seen as both an inexhaustible resource and a bottomless sink for our wastes. Yet the increasing pressures of overpopulation, pollution and the threat to our natural environment mean that there is an increasing need for scientists who can understand how it all works, how it affects us, and how we are affecting it from global warming through to the smallest plankton.
From local issues to global concerns, we now know that the marine environment is inextricably linked to our lives, and to our future survival. It is an area where much remains to be discovered, and where only a multidisciplinary approach can cover the breadth of issues to be confronted. This is the approach taken on our Marine Environmental Science degree course.
This course takes a multi-disciplinary approach to explore and understand the marine environment. After an initial grounding in basic science, optional choices are available in specialist topics such as marine ecosystems and pollution, coastal navigation and oceanography, among others.
Our new harbor side marine laboratory is used for some of the specialist lectures, laboratory and project work, while a week's residential field course in the Isle of Man provides training to prepare for the research project conducted in your final year. There is an optional trip to Belize in the final year to study tropical marine environments.
小題1: From the passage, we can infer that ______.
A.people waste a lot of resource
B.marine environment covers 3/4 of the surface of Mars

When I first began to work with international students, I asked someone at a lunch, “What brings you here today?” Looking at me like I was a bit crazy, he answered, “ The bus.” That was my first realization that no matter how good a speaker is, there are phrases that will always tend to cause confusion to non-native speakers. These idiomatic phrases(慣用語) add color and interest to any language and are worth learning if you want to talk fluently with native speakers.
“By no stretch”----The speaker is referring to something that’s very hard to achieve or realize, even with great effort, as in “It was not a good meal, by any stretch of the imagination.” Which means that ______________.
“Half dead”----An expression of extreme tiredness, having nothing to do with actual health. Commonly used at the end of a long and tiring day.
“By the book”----This means that an action should follow the rules exactly. It also describes the nature of someone who won’t deviate(背離) from a set of rules no matter what the situation is.
“More power to you”----This isn’t a wish for you to have better electricity from the power company----it’s a statement, usually slightly ironic(諷刺的), that the speaker thinks that you are unlikely to do a task, but you should try if you think you can complete it. It generally means the speaker has no intention of helping you achieve your goal neither will they discourage you from attempting to reach it. For example, “I don’t think you can meet that deadline, but more power to you.”
“As easy as pie”----A reference that something is as simple or easy as eating a delicious dessert, or that it requires little effort to successfully achieve. In chatting, this phrase does not refer to the process of cooking or eating.
小題1:The example given by the author in the first paragraph is used to show__________.
A.the importance of learning idiomsB.the beauty of the English language
C.the foolishness of the studentD.the cause of the misunderstanding
小題2:According to the passage, which of the following would be proper to fill in the blank in Paragraph 2?
A.the meal is very deliciousB.it’s very hard to make the meal delicious
C.people make great efforts to make the meal delicious
D.even if people try to believe it, the meal could not be described as good
小題3:If someone says he is half dead, he means____________.
A.he is in poor healthB.he cannot move
C.he has a sound sleepD.he is exhausted
小題4:If a person daren’t do things in a creative way, you may describe him by using “__________”.

Though “nanometer”(納米) is now a fashionable term all over the world, few people know
exactly what it is. It has become a new favorite of manufacturers and sellers in recent years.Many “high-tech” products bearing the name “nano” have entered the market,bringing more mysterious feeling to surprised consumers.
Nanometer is a very small length unit of measure,and is very small.One millimeter is 1000 micrometers,and one micrometer is 1000 nanometers.That is,one nanometer is one billionth of a meter.Nano materials are solid materials composed of particles(粒子)or crystallites(晶體) of less than 100 nanometer in size.Then,is a cup made of nano material really any different from an ordinary cup in function as far as how it works?
Are nano cups really so wonderful?A reporter went to the Institute of Nanomedicine,which is the first such institute of such a sort in the world and the only one in China,specializing in researching the investigation  of the application of nano technology into medicine.
A water molecule(分子) is composed of 2 hydrogen atoms and 1 oxygen atom.It can be changed only by special manipulation of the atoms. The material constituting the cup can have ananometer particles . But it cannot change the chemical and physical properties of the water contained in it.The water in the cup is still water. When people drink it,it will produce no special effect on human body.
Professor Ji who worked in the Instiute of Nanomedicine told the reporter, so far, the investigation of nano materials is still limited in the laboratory. No commercial micro products can be produced yet. With the present level of science and technology, the time of everyday goods made of nanometer materials is still years away.
The products labeled with nano marks in the market now are only traditional products coated with a thin layer of nanometer material, which makes them more abrasion resistant(耐磨), much easier to be cleaned, or oil resisting or moth proof(防蛀).
Professor Ji explained that nano cup is a real up. It can also be included in the list of nano products in a certain sense. But the nano up has not changed its property and function as a cup. It is not a magical medicine for curing and health care.
72.Which of the following shows the right relationship?
A.nanometer<millimeter<micrometer<meter
B.micrometer<millimeter<nanometer<meter
C.nanometer<micrometer<millimeter<meter
D.millimeter<micrometer<nanometer<meter
73.It can be inferred from the passage that       .
A.nano materials have been put into use in daily goods
B.real nano products haven’t become available for people
C.the nano cup is very effective in curing and health care
D.real nano products are being produced by some companies
74.The underlined word “properties” in the fourth paragraph probably means        .
A.possessions      B.qualities    C.reactions   D.symbols
75.What would be the best title for the passage?
A.High-tech Products  B.Nano Cups
C.Nano Materials        D.High-teach Research

Ten Chinese PhD students are demanding that Beijing Normal University Professor Yu Dan be away from her television show on CCTV 10. They argue that her on-air explanations of Confucius's Analects (《論語》) are "incorrect and misleading".
Yu is known for explaining Confucius's Analects to a TV audience, But some complain that her explanations are unfaithful to Chinese tradition.
But Yu doesn't seem to worry too much about her critics, saying, "It's a matter of personal choice. Some like KFC, while others like McDonalds."
STEALING some online gamer's password might seem less harmful than credit card theft. It does keep the victim from wearing himself out all night playing. But it is not all that nice, says 19-year-old Zhang Qiwen, in Shanghai.
Last August, Zhang accidentally downloaded a Trojan while playing Warcraft. The Trojan is a type of virus used by hackers to steal people's passwords. Overnight the Trojan transferred all the "gold" (game credits) from Zhang's private account to an unknown account. Zhaug hopes the police will find and punish the thief, who can also pocket some cash since the stolen "gold" can go on sale online.
New England's largest indoor public garden has opened here in a historic park, and officials expect it to become a center for learning about plants as well as a top attraction for visitors.
The glass-walled Roger Williams Park Botanical Center, which opened March 2. offers a tropical garden, an orchid garden, and a Mediterranean room with a collection of citrus trees, The center also has two classrooms and will offer gardening classes provided by the University of Rhode Island.
Roger Williams Park, named for the city's 17th-century founder, also has a zoo. The park already attracts more than 2 million visitors a year, and Providence Mayor David Cicilline said that he expects the new center will attract more and more visitors to Providence.

The world's oceans have warmed 50 percent faster over the last 40 years than previously thought due to climate change, Australian and US climate researchers reported on Wednesday. Higher ocean temperatures expand the volume of water, contributing to a rise in sea levels that is submerging small island nations and threatening to great damage in low-lying, densely-populated delta regions around the globe.
The study, published in the British journal Nature, adds to a growing scientific chorus of warnings about the pace and consequences of rising oceans. It also serves as a corrective to a massive report issued last year by the Nobel-winning UN Intergovernmental Panel on Climate Change(IPCC), according to the authors.
Rising sea levels are driven by two things: the thermal(熱)expansion of sea water, and additional water from melting sources of ice. Both processes are caused by global warming. The ice sheet that sits at the top of Greenland, for example, contains enough water to raise world ocean levels by seven metres(23 feet), which would bury sea-level cities from Dhaka to Shanghai.
Trying to figure out how much each of these factors contributes to rising sea levels is critically important to understanding climate change, and forecasting future temperature rises, scientists say. But up to now, there has been a confusing gap between the projections of computer-based climate models, and the observations of scientists gathering data from the oceans.
The new study, led by Catia Domingues of the Centre for Australian Weather and Climate Research, is the first to reconcile(與…一致)the models with observed data. Using new techniques to assess ocean temperatures to a depth of 700 metres(2,300 feet)from 1961 to 2003, it shows that thermal warming contributed to a 0.53 millimetre-per-year rise in sea levels rather than the 0.32 mm rise reported by the IPCC.
64. What happens when the ocean's temperature rises?
A. It causes sea levels to rise.
B. It causes sea levels to remain constant.
C. It causes sea levels to decrease.
D. It causes sea level to change.
65. Which of the followings would be buried by the rising sea?
A. Small island nations.
B. All coastal cities around the world.
C. People who enjoy holiday on the beach.
D. Low-lying regions.
66. The new study in this passage _____________.
A. shows that thermal warming contributed to a 0.32 millimeter-per-year rise in sea levels.
B. did not reveal anything that scientists hadn't already known.
C. used new techniques to assess ocean temperatures.
D. shows that models contradict the observed data.
67. What was the main finding of the study?
A. Nothing enough is being done about global warming.
B. That ocean waters have warmed faster than scientists had previously thought.
C. That the warming of the world's oceans is not a threat.
D. A massive report issued last year by IPCC was wrong.

D
  Beyond two or three days,the world’s best weather forecasts are doubtful, and beyond six or seven they are worthless.
  The Butterfly Effect is the reason. For small pieces of weather—to a global forecaster,small can mean thunder—storms and blizzards(暴風雪)—any prediction becomes worse rapidly. Errors and uncertainties increase,from dust devils and storms up to continent-size eddies(旋渦)that only satellites can see.
  The modern weather models work with net-like points sixty miles apart,and even so,some starting data have to be guessed,since ground stations and satellites cannot see everywhere. But suppose the earth could be covered with sensors placed one foot apart,rising at one-foot intervals all the way to the top of the atmosphere. Suppose every sensor gives perfectly accurate readings of temperature,pressure,humidity(溫度), and any other data a weatherman would want. Exactly at noon a powerful computer takes all the data and calculates what will happen at each point at 12.01, then 12.02,then 12.03…the computer will still be unable to predict whether Princeton will have sun or rain one month away. At noon the spaces between the sensors will hide fluctuations(波動)that the computer will not know about. By 12.01,those fluctuations will already have created small errors one foot away. Soon the errors will have added to the ten-foot scale,and so on up to the size of the globe.
63.A weather forecast ____________ in the world.
A.is reliable within one or two days
B.is doubtful beyond 24 hours
C.becomes useless beyond two or three days
D.is still worthwhile in seven days
64.Usually there is a weather sub-station____________.
A.in every city           B.every 60 miles
C.between two cities         D.every one foot
65.Which of the following statements is true?
A.People have not placed sensors one foot apart in the atmosphere.
B.Scientists have already put sensors one foot apart in the world.
C.Every sensor gives perfectly accurate data a weatherman wants.
D.Ground weather stations and satellites can see every place on earth.
66.Our computer will not be able to know about fluctuations because ____________.
A.the sensors are not good enough
B.they are hidden by the spaces between the sensors
C.they are too far away
D.they move very fast
