5.The strong emphasis on educational achievement in China,Japan and other parts of South-East Asia may be coming at a heavy price.Researchers say that hard work at school plus the lack of exposure to outdoor light is damaging the eyes of almost nine out of ten students-with one in five at serious risk of visual impairment and blindness.
The scientists say that young people need up to three hours a day of outdoor light,but many infants are also missing out as they nap during lunch time.Dr.Ian Morgan is the lead author of the study."I think what's happened in South-East Asia is that we've got a double whammy.We've got the massive educational pressures and we've got the construction of a child's day in a way that really minimises the amount of time they spend outside in bright light."
The scientists say that genetic factors,long thought to play a big role in short-sightedness,are not as important as the environment.They point to Singapore as a place with several different racial groups,all of whom are now suffering high levels of short-sightedness.
The authors suggest that compulsory time outdoors should be considered by educational authorities across South-East Asia as a way of dealing with the problem.

15.The more time scientists spend designing computers,the more they wonder at human brain.Tasks that puzzle the most advanced supercomputer-recognizing a face,reading a handwritten note-are just child's play for the 3-pound organ(器官).Most important,unlike any ordinary computer,the brain can learn from its mistakes.Researchers have tried for years to program computers to imitate the brain's abilities,but without success.
Now a growing number of designers believe they have the answer:if a computer is to work more like a person and less like an over-grown calculator,it must be built more like a brain,which distributes information across a vast interconnected web of nerve cells or neurons.
Ordinary computers work by following a chainlike sequence of detailed instructions.Although very fast,their processors can perform only one task at a time.This approach works best in solving problems that can be broken down into simpler logical pieces.The processors in a neural-network computer,by contrast,form a network much like the nerve cells in the brain.Since these artificial neurons are interconnected,they can share information and perform tasks at the same time.This two-dimensional approach works best at recognizing patterns.
Instead of programming a neural-network computer to make decisions,its maker trains it to recognize patterns in any solution to a problem by repeatedly feeding examples to the machine.Neural networks come in all shapes and sizes.Until now most existed as software simulatio ns (模拟品) because redesigning computer chips took a lot of time and money.By experimenting with different approaches through software rather than hardware,scientists have been able to avoid costly (昂贵的) mistakes.
56.It can be inferred from the first two paragraphs that the most advanced supercomputerD.
A.can recognize a face and read a handwritten note
B.can learn from its mistakes
C.weighs only 3 pounds
D.can't distribute information across an interconnected web of nerve cells
57.An ordinary computer can usually do the following except thatD.
A.it must be programmed before it works
B.it can only solve one problem at a time
C.it is good at solving problems that can be broken down into simpler logical pieces
D.it is trained to make decisions
58.The main feature of a neural-network computer is thatA.
A.its processors act as an interconnected web of neurons
B.it is programmed to make decisions
C.its networks are of all shapes and sizes
D.its neurons are artificial
59.What does"this two-dimensional approach"in the third paragraph refer to?C
A.the conventional computer and the neural computer.
B.making decisions and recognizing patterns.
C.sharing information and performing tasks.
D.the computer and the human brain.
60.Scientists use software rather than hardware in their experiments becauseB.   
A.it can avoid redesigning computer chips

16.Memory,they say,is a matter of practice and exercise.If you have the wish and really made a conscious(自觉的) effort,then you can quite easily improve your ability to remember things.But even if you are successful,there are times when your memory seems to play tricks on you.
Sometimes you remember things that really did not happen.One morning last week,for example,I got up and found that I had left the front door unlocked all night,yet I clearly remember locking it carefully the night before.
Memory"trick"work the other way as well.Once in a while you remember not doing something,and then find out what you did.One day last month,for example,I was sitting in a barber shop waiting for my turn to get a haircut,and suddenly I realized that I had got a haircut two days before at the barber shop across the street from my office.
We always seem to find something funny and amusing in incidents caused by people's forgetfulness or absent-mindedness.Stories about absent-minded professors have been told for years,and we never get sick of hearing new ones.Unfortunately,however,absent-mindedness is not always funny.There are times when"trick"of our memory can cause us great trouble.
8.If you want to have a good memory,B.
A.you should force yourself to remember things
B.you should make a conscious effort of practice and exercise

13.You may have experienced the annoyance of being fined because of parking illegally or finding your car towed away(拖走)after leaving it parked somewhere for a couple of minutes.But now a high-tech car sticker that's designed to be stuck to a car's windscreen could help motorists avoid such a situation.
The TowStop sticker sends a text message to a driver when touched by a traffic policeman,to allow motorists to send a reply and give them time to move their cars immediately.Frankfurt-based IT consultant,Daniel Kalliontzis,came up with the idea and is raising money to put his£43sticker into production.
Car owners can put the sticker inside their car's windscreen,having set it up with key information,such as their phone number.The slim design will include a sensor(传感器)that,when touched by a traffic policeman,will send a text message warning a driver of a possible fine.The driver could then type a reply for the policeman using a smartphone,which will appear on the sticker's screen.
The smart sticker system will rely on the good will of traffic policemen and in a way,a German law.The law states:an officer has to choose the most efficient and inexpensive way for the car owner to remove the vehicle.It could be cheaper for the government to call the driver than to tow his car.
Mail Online asked the Department of Transport whether the sticker could be used in the UK in a similar way.A spokesman said,"In England there is no legal duty to warn the motorist before issuing the ticket.However,a policeman does have the discretion not to issue a ticket if he doesn't think the situation is that bad or he just wants to issue a warning."
So far,Mr.Kalliontzis has raised just over£2,362of his£39,381goal.If he manages to raise the money,the stickers will be shipped in June 2015.But it appears that car owners using the smart system could get some unnecessary warning messages,because anyone could touch the smart sticker.
28.The author wrote the third paragraph toA.
A.explain how a smart car sticker works
B.advise drivers to buy a car sticker
C.show the importance of a sensor
D.tell drivers how to park a car
29.We may infer from the text that in BritainB.
A.car owners don't have to worry about a parking ticket
B.smart car stickers wouldn't work as well as in Germany
C.traffic policemen prefer to call a driver rather than tow his car
D.the Department of Transport thinks highly of smart car stickers
30.The underlined word"discretion"in Paragraph 5can best be replaced by"C".
A.trouble     
B.pressure       
C.freedom 
D.opportunity
31.What would be the best title for the text?D
A.Daniel Kalliontzis-a great inventor         
B.Environment-friendly car stickers
C.Parking systems in Europe                      
D.End of the parking ticket?

10.Many animals recognize their food because they see it.So do humans.When you see an apple or a piece of chocolate you know that these are things you can eat.You can also use other senses when you choose your food.You may like it because it smells good or because it tastes good.You may dislike some types of food because they do not look,smell or taste very nice.Different animals use different senses to find and choose their food.A few animals depend on only one of their senses,while most animals use more than one sense.
Although there are many different types of food,some animals spend their lives eating only one type.The giant panda eats only one particular type of bamboo.Other animals eat only one type of food even when given the choice.A kind of white butterfly will stay on the leaves of a cabbage,even though there are plenty of other vegetables in the garden.However,most animals have a more varied diet.The bear eats fruits and fish.The fox eats small animals,birds and fruits.The diet of these animals will be different depending on the season.
Humans have a very varied diet.We often eat food because we like it and not because it is good for us.In countries such as France and Britain,people eat foods with too much sugar.This makes them overweight,which is bad for their health.Eating too much red meat and animal products,such as butter,can also be bad for the health.Choosing the right food,therefore,has become an area of study in modern life.

21.We can infer from the text that humans and animalsC.
A.depend on one sense in choosing food
B.are not satisfied with their food
C.choose food in similar ways
D.eat entirely different food
22.Which of the following eats only one type of food?A.
A.The white butterfly.
B.The small bird.
C.The bear.
D.The fox.

A.the season changes
B.the food color changes
C.they move to different places
D.they are attracted by different smells

A.food is chosen for a good reason
B.French and British food is good
C.some people have few choices of food

15."I sometimes get up at three or four in the morning and I surf the net."
"I often check my e-mail forty times a day."
"I often spend more than three hours during one time on the net."
"I spend more time in chat rooms(聊天室) than with my‘real-1ife'friends."
Do you know any people like these?They are part of a new addiction(瘾) called Internet addiction.Internet addicts spend at least thirty to forty hours online every week.The use of the Internet can be an addiction like drug(毒品) use.People lose control(控制)of the time they spend on the Internet
For example,one college student was missing for several days.His friends were worried,and they called the police.The police found the student in the computer lab:he was surfing the net for several days straight.
Studies show that about 6 to 10% of Internet users become addicted.And people worry about the teens because the Internet is changing the playing field for some of them.They spend more time in cyberspace than in the real world of friends and family.
Is"surfing the net"a hobby or an addiction for you?You may have a problem if
you have these symptoms(症状):
●You do no t go to important family activities or you do not do school work because you like to spend hours on the Internet.
●You can't wait for your next online time.
