Sports shoes that work out whether their owner has done enough exercise to warrant time in front of the television have been devised in the UK.
The shoes — named Square Eyes — contain an electronic pressure sensor and a tiny computer chip to record how many steps the wearer has taken in a day. A wireless transmitter(傳話器) passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer deserves, based on the day’s efforts.
The design was inspired by a desire to fight against the rapidly ballooning waistlines among British teenagers, says Gillian Swan, who developed Square Eyes as a final year design project at Brunel University to London, UK. “We looked at current issues and childhood overweight really stood out,” she says. “And I wanted to tackle that with my design.”
Once a child has used up their daily allowance gained through exercise, the television automatically switches off. And further time in front of the TV can only be earned through more steps.
Swan calculated how exercise should translate to television time using the recommended daily amounts of both. Health experts suggest that a child take 12,000 steps each day and watch no more than two hours of television. So, every 100 steps recorded by the Square Eyes shoes equals precisely one minute of TV time.
Existing pedometers （計步器） normally clip onto a belt or slip into a pocket and keep count of steps by measuring sudden movement. Swan says these can be easily tricked into recording steps through shaking. But her shoe has been built to be harder for lazy teenagers to cheat. “It is possible, but it would be a lot of effort,” she says. “That was one of my main design considerations.”
小題1:According to Swan, the purpose of her design project is to ________.
A．keep a record of the steps of the wearer
B．deal with overweight among teenagers
C．enable children to resist the temptation of TV
D．prevent children from being tricked by TV programs
小題2:Which of the following is true of Square Eyes shoes?
A．They regulate a child’s evening TV viewing time.
B．They determine a child’s daily pocket money.
C．They have raised the hot issue of overweight.
D．They contain information of the receiver.
小題3:What is stressed（強(qiáng)調(diào)）by health experts in their suggestion?
A．The exact number of steps to be taken.
B．The precise number of hours spent on TV.
C．The proper amount of daily exercise and TV time.
D．The way of changing steps into TV watching time.
小題4:Compared with other similar products, the new design ________.
A．makes it difficult for lazy teenagers to cheat
B．counts the wearer’s steps through shaking
C．records the sudden movement of the wearer
D．sends teenagers’ health data to the receiver
小題5:Which of the following would be the best title for the text?
A．Smart Shoes Decide on Television Time
B．Smart Shoes Guarantee More Exercise
C．Smart Shoes Measure Time of Exercise
D．Smart Shoes Stop Childhood Overweight

小題1:B
小題2:A
小題3:C
小題4:A
小題5:A

小題1:這是一道推斷題。根據(jù)第三段“‘We looked at current issues and childhood overweight really stood out,’she says,‘And I want to tackle that with my design .’”可以推斷出這個設(shè)計是為了解決孩子超重的問題。
小題2:這是一道推斷題。根據(jù)第四段“Once a child has used up their daily allowance gained through exercise, the television automatically switches off. And further time in front of the TV can only be earned through more steps.”可知這種鞋利用走路的步數(shù)來控制孩子看電視的時間。
小題3:這是一道推斷題。根據(jù)第五段“Health experts suggest that a child take 12 000 steps each day and watch no more than two hours of television.”可以推斷出健康專家給出了每天合適的運(yùn)動量和看電視時間。
小題4:這是一道推斷題。根據(jù)最后一段“Swan says these can be easily tricked into recording steps through shaking. But her shoe has been built to be harder for lazy teenagers to cheat.”可以推斷出類似產(chǎn)品可以用晃動來作弊,但是她設(shè)計的鞋使得懶惰的青少年很難作弊。
小題5:這是一道主旨題。本文主要介紹了一款智能運(yùn)動鞋,利用孩子們每天的走步數(shù)來決定看電視的時間,起到控制體重的作用。

If there is no difference in general intelligence(智力)between boys and girls,what can explain girls' poor performance in science and mathematics?
It seems to be that their treatment at school is a direct cause.Mathematics and science are seen as subjects mainly for boys,and therefore ,as girls become tee
nagers,they are less likely to take them.Interestingly,both boys and girls often
regard the subjects for boys as more difficult.Yet it has been suggested that girls do not take mathematics courses ,not because they are difficult,but for social reasons.Girls do not want to be in open competition with boys because they are afraid to appear less feminine(女性的)and attractive.
However,if we examine the performance of boys and girls who have taken mathematics courses,there are still more high?achieving boys than there are girls.This difference appears to be world?wide.Biological explanations have been offered for this,but there are other explanations too.
Perhaps the difference which comes out during the teenage years has its roots in much earlier experiences.From their first days in kindergarten,boys are encouraged to work on their own and to complete tasks.Facts show that outstanding(杰出的)mathematicians and scientists have not had teachers who supplied answers.
Besides,there can be little doubt that teachers of mathematics and science expect their boy students to do better at these subjects than their girl students.They even appear to encourage the difference between boys and girls.They spend more time with the boy students ,giving them more time to answer questions and working harder to get correct answers from them.They are more likely to call on boys for answers and to allow them to take the lead in classroom discussion.They also praise boys more frequently.All of this seems to encourage boys to work harder in science and mathematics and to give them confidence(信心)that they are able to succeed.
Such a way of teaching is not likely to encourage girls to take many mathematics
and science courses,nor is it likely to support girls who do.When it comes to these subjects it seems certain that school widens the difference between boys and girls.
1.Girls are likely to think that____________.
A.science courses are for both boys and girls
B.science courses make them more popular
C.science courses make them successful        
D.science courses are difficult for them          
2.The text mainly discusses_____________reasons for the difference between boys and girls in scientific achievements. 
A.biological         B.historical          C.social       D.personal          
3.What are boys usually encouraged to do at school?
A.To get help with their homework.        
B.To play the leading role in class.        
C.To work with girl students in class.        
D.To learn to take care of others.          
4.What does the passage say about great mathematicians?        
A.Their teachers did not supply answers to them.        
B.They started learning mathematics at an earlier age.        
C.They showed mathematical abilities in their teenage years.
D.Their success resulted from their strong interest in mathematics.?
5.The author would probably agree that_____________.
A.boys and girls learn in the same way        
B.boys and girls are equal in general intelligence        
C.girls are more confident in themselves than before        
D.girls should take fewer science courses than boys

Today about 70 countries use Daylight Saving Time (DST). Daylight Saving was first introduced during World War I in Australia. During the world wars, DST was used for the late summers beginning January 1917 and 1942, and the full summers beginning September 1942 and 1943.  
In 1967, Tasmania experienced a drought（干旱）. The State Government introduced one hour of daylight saving that summer as a way of saving power and water. Tasmanians liked the idea of daylight saving and the Tasmanian Government has declared daylight saving each summer since 1968. Persuaded by the Tasmanian Government, all states except two passed a law in 1971, for a test use of daylight saving. In 1972, New South Wales, South Australia and Victoria joined Tasmania for regular daylight saving, but Queensland did not do so until 1989.
Tasmania, Queensland and South Australia have had irregular plans, often changing their dates due to politics or festivals（節(jié)日）. For example, in 1992, Tasmania extended（延長）daylight saving by an extra month while South Australia began extending daylight saving by two weeks for the Adelaide Festival. Special daylight saving plans were made during the Sydney 2000 Olympic Games.
The differences in daylight saving in Australia continue to cause serious problems in transport and many other social activities. It also reduces the number of hours in the working day that are common to all centers in the country. In particular, time differences along the east coast cause major differences, especially for the broadcasters of national radio and television.
小題1:Daylight Saving Time was introduced in Tasmania _______________.
A．to stop the drought in 1967B．to support government officials
C．to pass a special law in the stateD．to save water and electricity
小題2: According to the text, which state was the last to use DST?
A．Victoria.B．Queensland.
C．South Australia.D．New South Wales.
小題3: What can we learn about DST in some Australian states?
A．It doesn’t have fixed dates.B．It is not used in festivals.
C．Its plan was changed in 2000.D．It lasts for two weeks.
小題4: What do we know about the use of DST from the last paragraph?
A．There exist some undesirable effects.B．It helps little to save energy.
C．It brings about longer working days.D．Radio and TV programs become different.

16 some aspects of language are undeniably innate, language does not develop automatically in a vacuum.Children who have been 17 from other human beings do not possess language.This demonstrates that 18 with other human beings isnecessary for proper language development.Some linguists believe that this is even more basic to human language 19 than any innate capacities.These theorists view language as imitative, learned behavior. 20 , children learn language from their parents by imitating them.Parents gradually shape their child's language skills by positively reinforcing precise imitations and negatively reinforcing imprecise ones.

Speakers of different languages not only describe the world differently but think about it differently too, according to a new study.
Researchers used a cartoon cat Sylvester to study how language was reflected (反映) in the gestures people made. Dr. Sotaro Kita of the University of Bristol’s Department of Experimental Psychology (心理學(xué)), showed the cartoon to a group of native English, Japanese and Turkish speakers and then watched their gestures as they described the actions they had seen. He found speakers of the three different languages used different gestures to describe the same event, which appeared to reflect the way the structure of their languages expressed that event. For example, when describing a scene where the cat swings on a rope, the English speakers used gestures showing an arc trajectory (弧形軌跡)  and the Japanese and Turkish speakers tended to use straight gestures showing the motion but not the arc.
Dr. Kita suggests this is because Japanese and Turkish have no proper verb to express the English meaning “to swing”. While English speakers use the arc gesture as their language can readily express the change of location and the arc-shaped trajectory, Japanese and Turkish speakers cannot as easily express the idea of movement with an arc trajectory so they use the straight gesture.
Dr. Kita said, “My research suggests that speakers of different languages cause different spatial (空間的) images of the same event in a way that matches the expressive possibilities of their own languages. In other words, language influences (影響) spatial thinking at the moment of speaking.”
68. 小題1:Researchers watched the gestures the people made because they wanted to know _____.
A．how language was reflected
B．whether they could express the same idea
C．whether they could describe what they had seen
D．how the structure of language changed
69. 小題2:After watching the gestures of speakers of the three different languages, Dr. Kita concluded that _____.
A．Japanese and Turkish people couldn’t express the meaning of “swing”
B．English was obviously better than Japanese and Turkish
C．no word in Japanese and Turkish could express some ideas of English
D．every language had its own special way to describe things
70.小題3:What is mainly discussed in the text?
A．Differences between languages.
B．Differences between gestures.
C．How people use different gestures to express the same event.
D．That language influences the way people think.

So much to do, so little time．So much information, so little time to read ．In this age there is more information than ever before．There is not enough time to read everything we want to read．However, you can take in and understand more information in shorter time through speed-reading．This article will not make you read 3 000 words per minute, but it will show you how to increase your speed greatly．You will also learn the basic techniques of speed reading, along with the dos and don'ts of speed-reading．
When you first learned to read, you would say the word out loud and sound it out．Then you might whisper the word because people can become annoyed when you read aloud．The stage you are now at is saying the word in your head．Most people tend to read this way．Saying the word in your head will cut your reading speed tremendously (極大的)．
How do you calculate your reading speed? The speed is measured by how many words per minute you can read．Get some reading material, preferably a book．Find out how many words are on the page．Time yourself one minute．Start your timer and start reading．When the timer sounds, stop at once．If you counted 500 words on the page and you read half of the page, then you are probably reading at 250 words per minute．
The first thing about speed-reading is looking at the word and recognizing it．Don't say the word in your mind, just look at it and recognize its appearance．Later you will recognize groups of four words or more to increase your speed．This is the first and most important step in speed-reading．
The next step is technique．As with any other skill, speed-reading requires technique．You should first be sitting up straight with your book on a horizontal (水平的) surface, such as a table or desk．Next, should be able to see the entire page．This is necessary if you want to recognize clumps of words．Lastly, you should be focused．It's hard to read a lot of noise．Find a quiet place to read．This will help your understand of the text．You need something to guide your eyes while reading．Then right, you should use your hand, Remember when you were little, you would read using your finger．That is a great technique, only now you're using your hand to underline each line．Move your finger smoothly across page．No need to go rush , start our slow．Keep your eyes focused on words as you recognize them while using your hand as a guide．This will increase you speed．
The third step is practice．Practice makes perfect．Set time intervals(間歇)．Read using different techniques, but make sure you understand what you're reading．
小題1:Which of the following statements is true according to the text?
A．Now there is limited information than ever before．
B．Now conditions ask people to use less time to know more information．
C．Now people can read what they like．
D．The less you read, the more time you will spend．
小題2:What is the subject discussed in the text?
A．What speed-reading is．
B．Why we need speed-reading．
C．Now it is much information time．
D．People should practice speed-reading in different kinds of ways．
小題3:Which of the following shows the right way for the speed-reading from the text?
a．Ask for some techniques．
b．Look at many words and recognize them．
c．Practice more．
A．c,a,bB．c,b,aC．b,a,cD．a(chǎn),c,b
小題4:The underlined sentence“you should be focused”in the fifth paragraph means that _________．
A．a(chǎn) person should devote his attention to it while reading
B．your feelings will be hurt while reading

Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air， water and sunlight. Animals and man cannot make food from air， water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us.
If you look carefully at the plants around you， you will find that there are two kinds of plants： flowering plants and non-flowering plants. Flowering plants can make seeds. The seeds are protected by the fruits. Some fruits have one seed， some have two， three or four， and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores（胚芽）。 Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places， they usually grow into new plants.
62.小題1:The main idea of the first paragraph is that ______.
A．plants are important for lifeB．plants cannot grow without air
C．there are many plants in the worldD．we can not live without water
63.小題2:What can we infer（推斷） from the passage ？
A．Of all living things animals are most.B．Spores are seeds.
C．All fruits of flowering plants have seeds.D．Without plants，man will die out.
64.小題3:What is the meaning of the underlined word?
A．Kept.B．Guarded.C．Prevented.D．Surrounded
65.小題4:This passage may be taken from______.
A．a(chǎn) medicine bookB．a(chǎn) novel
C．a(chǎn) science magazineD．a(chǎn)n experiment report

Industrial pollution is not only a problem for the countries of Europe and North America but also an extremely serious problem in some developing countries. For these countries, economic growth is a very important aim. They want to introduce industries, and so they put few controls on the industries which cause pollution.
Cubatao, an industrial town of 85 000 people in Brazil, is an example of the connection between industrial development and pollution. In 1954, Cubatao had no industry. Today it has more than twenty large factories, which produce many pollutants(污染物). The people of the town are suffering from the poisonous matter in their environment and the bad effects can be clearly seen. Birth shortcomings are extremely common. Among children and adults, lung problems are sometimes twelve times more common in Cubatao than in other places.
It is true that Brazil, like many other countries, has laws against pollution, but these laws are not enforced strictly enough. It is cheaper for companies to take no notice of the laws and pay the fines(罰款) than to buy the expensive equipment that will reduce the pollution. It is clear, therefore, that economic growth is more important to the government than to the health of the workers. However, the responsibility(責(zé)任) does not completely lie with the Brazilian government. The example of Cubatao shows that international companies are not acting in a responsible way either. A number of the factories in the town are owned by large companies from France, Italy, and the U. S. They are doing things in Brazil that they would not be able to do at home. If they caused the same amount of pollution at home, they would be severely(嚴(yán)厲地) punished or even put out of business.
小題1:Why don’t developing countries have strict pollution controls?
A．The new industries they want to introduce do not cause much pollution.
B．Pollution is not a serious problem for developing countries.
C．They don’t realize the balance of nature will be destroyed by some pollutants.
D．If they put stricter controls on industry, fewer companies would build new plants in developing countries.
小題2:What is the author’s purpose in taking Cubatao as an example?
A．To show that industry can develop very fast in developing countries.
B．To show that the pollution problem in Brazil is extremely serious.
C．To show that industrial growth can cause pollution problems for developing countries.
D．To show that pollution is killing many people and destroying the whole economy of Brazil.
小題3: How is the health of the population of Cubatao?
A．There are more heart diseases among people who live near chemical factories.
B．More people suffer from lung diseases because of poisonous matter.
C．Their health is affected by pollutants the same way as that of other Brazilians.
D．Babies there are found not as bright as those who live in other places.
小題4:Why do some foreign companies like to set up their plants in Brazil?
A．The investment(投資) environment in Brazil is suitable for them.
B．They will not be severely punished if they cause pollution in Brazil.
C．They can make much money because they do not have to pay Brazilian workers much.
D．They can act in an irresponsible(不負(fù)責(zé)任的) way in Brazil because there are no pollution laws there.
