A team of US psychologists have found that talking to another person for ten minutes a day helps with memory.
"Socializing is just as effective as more traditional kinds of mental exercise in boosting memory and intellectual performance," Oscar Ybarra, a psychologist at the University of Michigan Institute for Social Research, said in a statement.
In one investigation, they analyzed data on 3610 people, aged 24 to 96.
They found that the higher their level of social interaction (交流), the better their cognitive (認(rèn)知的) functioning.  Social interaction includes getting together or having phone chats with relatives, freinds and neighbors.
In another experiment, the researchers conducted lab tests on 76 college students, aged 18 to 21, to evaluate how social interactions and intellectual exercises affected the results of memory and mental performance tests.
The students were divided into three groups: the social interaction group had a discussion of a social issue for 10 minutes before taking the tests; the intellectual activities group completed three tasks (including a reading comprehension exercise and a crossword puzzle) before the tests; and a control group (對(duì)照組) watched a 10-minute clip (電源片段) of the Seinfeld television show.
"We found that short-term social interaction lasting for just 10 minutes improved participants’ intellectual performance as much as engaging in so-called ’intellectual’ activities for the same amount of time," Ybarra said.
The study was expected to be published in the February issue of the journal Personality and Social Psychology Bulletin.

In many parts of the world, cars play an important role in daily life and many societies would not exist without them.  【小題1】 But this is the prediction made by a team of transport researchers who are taken seriously, not only by government but also by car manufacturers.
The Human Science and Advanced Technology Institute at Loughborough in the UK is part of an international research program.  【小題2】 That will mean much saving, no accidents and better use of roads. The super-intelligent car in the future will drive itself.  【小題3】 Instead, we will have a choice of cars and change them as frequently as we change our clothing.
According to Dr. David Davis, who leads the research team, these predictions are based on the rising cost of the car culture, which had blocked up our cities, polluted our air, and caused more deaths than both world wars put together.
Davis says, cars will be fitted with some intelligent devices(裝置) to regulate(調(diào)節(jié)) the distance between one car and another.  【小題4】 computers are much safer drivers than people, so cars in a road train will be able to drive much closer together than cars driven by people.
By 2010, Dr. David Davis believes, car technology will give motorists a clear view of the road, whatever the weather conditions, by projecting an image of the road ahead on to the car’s windscreen.  【小題5】 Cars will be connected by an electronic tow bar to the car in front to form “road-trains”. “The front vehicle in such a train burns the normal amount.”says Davis. “but all the others in the train would burn about ten percent of the normal amount,  and so produce about ten percent of the pollution.”

A．The team there believes that by 2030 all cars will be computerized.
B．They believe that cars will become more important in 20 years.
C．And it will not be owned by one individual.
D．And by 2030, cars will travel in line, linked to each other electronically.
E.So the idea that in 20 years’ time, no one will own cars may be hard to believe.
F.Every driver will use less fuel in the car he owns.
G.The car will automatically speed up, or slow down, to match the speed of the car in front.

I shall never forget the day when the earthquake took place. The time was about 5 o’clock in the afternoon and I was driving along the road to take my daughter from school. Our plan was to go swimming together. I had finished my work at 4 o’clock and then gone to the Post Office. Then I’d stopped off at a shop in order to get some fresh fruit. We like to have some fruit to eat after our swim.

I was driving along a high road on my way to my daughter’s school. Over my road was another road which was built like a bridge for cars coming to the other way. I was hungry so I put the bag of apples in the seat beside me and started to eat one.

Suddenly I saw the cars in front of me start to move from side to side. Then my car started to shake! I didn’t know what was happening. Perhaps something had gone wrong with my car. I drove a little more slowly and then I stopped the car and at the same moment the road fell onto the cars in front of me.

I found myself in the dark. I couldn’t move. The bottom parts of both of my legs and my feet were hurting badly and I couldn’t move them. All around me was quiet. But above me I could hear shouts and a lot of noise. Then I memorized (記起) what had happened. I had been in an earthquake.

For about two hours nobody came. Luckily I could reach the bag of apples, so at least I had plenty to eat. Then I heard people climbing towards me. A team of people had come to see if anyone was under the broken road. I called out. “I’m here!” I heard a shout. Soon a stranger climbed to the side of the road near my car. “How are you doing?” he asked.

“Not too bad,” I said, “but my feet and leg feel as if they’re broken.” “We’ll have you out of there just as soon as we can.” They didn’t get me out until the next morning. I had been in my car for fourteen hours.

1.When the earthquake took place, the writer was ______.

A. on his way to the Post Office    B. stopping off a shop

C. doing some shopping          D. under a road built like a bridge

2.The writer’s car began to move from side to side because ________.

A. there was something wrong with his car

B. he ate apples as he drove

C. an earthquake began to happen

D. he drove too fast

3.Which is the following is TRUE according to the passage?

A. When the earthquake happened, the writer was with his daughter together.

B. The writer’s leg and feet were badly wounded in the earthquake.

C. The writer was saved as soon as the stranger climbed up the road.

D. The writer was frightened that he forgot everything that happened around.

Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings. The noise that affects sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.

Decibels(分貝) measured in water are different from those measured on land. A noise of 120 decibels on land causes pain to human ears. In water, a decible level of 195 would have the same effect.

Some scientists have suggested setting a noise limit of 120 decibles in oceans. They have observed that noises above that level can frighten and confuse whales.

A team of American and Canadian scientists discovered that loud noises could seriously injure some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing, which seriously affected the whales’ ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected(感染的).

Many researches whose work depends on ocean sounds disagree with a limit of 120 decibels. They say such a limit would mean an end to important industrial and scientific research.

Scientists do not know how many and what kinds of noises are harmful to ocean animals. However, many scientists suspect that noise is a greater danger than they previously believed. They want to prevent noises from harming creatures in the ocean.

1.The second paragraph mainly tells us that the noises on land and in water       .

A．a(chǎn)re both from human activities.

B．both do harm to sea animals

C．a(chǎn)re measured differently

D．have the same effect on humans

2.As to(依據(jù)) the effects of noises on whales, which of the following statements is TRUE according to the passage?

A．They are deaf to noises.

B．Noises at a certain level may hurt them.

C．They are easily confused by noises.

D．Noises will limit their ability to reproduce.

3.Many researchers think that the noise limit of 120 decibels would        .

A．protect whales from noises

B．benefit them a lot in their research work

C．do good to their health

D．increase industrial output

4.What will scientists most probably do in the future?

A．Count the number of sea animals.

B．Stop their research on the ocean.

C．Study the effect of different noises.

D．Protect sea creatures from harmful noises.

Half of the world’s population is affected by Asian monsoons (季風(fēng)), but monsoons are difficult to predict. American researchers have put together a 700-year record of the rainy seasons, which is expected to provide guidance for experts making weather predictions.

Every year, moist (潮濕的) air masses，known as monsoon，produce large amounts of rainfall in India, East Asia, Northern Australia and East Africa. All this wet air is pulled in by a high pressure area over the Indian Ocean and a low pressure area to the south.

According to Edward Cook, a weather expert at Columbia University in New York, the complex nature of the climate systems across Asia makes monsoons hard to predict. In addition, climate records for the area are too recent and not detailed enough to be of much use. Therefore, he and a team of researchers spent more than fifteen years traveling across Asia, looking for trees old enough to provide long-term records. They measured the rings（年輪）, or circles, inside thousands of ancient trees in more than 300 places.

Rainfall has a direct link to the growth and width of rings on some kinds of trees. The researchers developed a document they are calling a Monsoon Asia Drought Atlas. It shows the effect of monsoons over seven centuries, beginning in the 1300s.

Professor Cook says the tree-ring records show periods of wet and dry weather. “If the monsoon basically fails or is a very weak one, the trees affected by monsoons at that location might put on a very narrow ring. But if the monsoon is very strong, the trees affected by that monsoon might put on a wide ring for that year. So, the wide and narrow ring widths of the chronology（大事年表） that we developed in Asia provide us with a measure of monsoon variability.” With all this information, researchers say they can begin to improve computer climate models for predicting the behavior of monsoons.

“There has been widespread famine and starvation and human dying in the past in large droughts. And on the other hand, if the monsoon is particularly heavy, it can cause extensive flooding.” said Eugene Wahl, a scientist with America’s National Oceanic and Atmospheric Administration. “So, to get a sense of what the regional moisture patterns have been, dryness and wetness over such a long period of time in great detail, I would call it a kind of victory for climate science.”

1.What’s the passage mainly about？

A．The effects of Asian monsoons.             B．The necessity of weather forecast.

C．The achievements of Edward cook.          D．A breakthrough in monsoon prediction.

2.It is difficult for experts to predict Asian monsoons because _______.

A．it is hard to keep long-term climate records.

B．they are formed under complex climate systems.

C．they influence many nations.

D．there is heavy rainfall in Asia.

3.What can be inferred from the passage?

A．Long and detailed climate records can offer useful information for monsoon research.

B．The Monsoon Asia Drought Atlas has a monsoon record for about 1,300 years.

C．The trees affected by monsoon grow fast if the monsoon is weak.

D．The rainfall might be low although the monsoon is strong in monsoon-affected areas.

4.According to Professor Cook, the rings of the trees _______.

A．determine the regional climate.

B．have a great influence on the regional climate.

C．offer people information about the regional climate.

D．reflect all kinds of regional climate information.

5.What do we know about the research according to Eugene Wahl?

A．It is a great achievement in climate science.

B．It should include information about human life in the past.

C．It has analysed moisture models world wide,

D．It will help people prevent droughts and floods.

6.Which of the following best describes the tone of this passage?

A．Matter-of –fact    B．Pessimistic         C．Humorous         D．Friendly.
