Through history, children have played with toys and they help to prepare children for adult life. But the toys are changing all the time. As science and technology have changed the way adults live, the toys children play with have changed as well. Developments in science and technology have had a big effect on the toys that children play with. Today trains and mobile phones are popular toys for young children, but there were no toys of this kind before real trains and mobile phones were invented.  The materials that toys are made of have also changed.  Today lots of toys are made of plastic. Plastic is a modern, man-made material that did not exist (存在) in the past. On the other hand, some other toys that you have might not be all that different from the ones children played with 1,000 years ago. Scientists have found some bone dice (骰子)in Aberdeen. In medieval (中世紀(jì)的)times dice were used for playing games as much as they are today.
A recent survey found that half of all the children aged from 4 to 6 have played video games, a quarter of them regularly. The increasing use of electronic toys troubles Dr Singer, a professor at Yale. “One thing we know is that kids in early years need to be in touch with the real world,” he said, “No matter how brilliant they are, they’re not going to learn to walk, to move or to talk to others unless their hands or feet have a direct role in such activities.”
Some toy experts argue that the best toys are the ones that increase a child’s creativity and imagination. Traditional toys can be used for different kinds of purposes and be used in group settings, individually(單獨(dú)地), and one-to-one. They are also used differently depending on the child’s age and skill level. And these toys made of natural materials are valuable for children because they teach children what the world is made of.
【小題1】In how many ways do toys change according to the first paragraph?

A．One.B．Two.C．Three.D． Four.
【小題2】From the article, we can know that     .
A．only children like to play with toys
B．toys have nothing to do with children’s future life
C．the development of toys is related to science and technology
D．plastic is the best material for making toys
【小題3】According to Dr Singer,     .
A．the electronic toys are good for children if they play often enough
B．the electronic toys prevent children keeping in touch with the real world
C．children should be stopped from being hurt by the danger coming from the outside world
D．children should play with electronic toys instead of the traditional ones

Shelly Nielsen sees students fall asleep in class at least twice a week. “When I see teens asleep in my class, I wonder if I am really that boring”, said Nielsen, a teacher. “I also wonder why they are so tired.” Neilson first tried to wake up sleeping students quietly. If the snoozing (呼嚕聲) continues, she may call a student’s parents to find out how much sleep the students is getting at night and why.
According to a research, teens need at least nine hours of sleep to function properly during the day. And more than 90 percent of teens say they are sleeping less than that each night.
Forgetting homework, yawning in class, losing concentration --- these are the signs of a sleep-deprived (被剝奪睡眠的)student, said Dr. Carl Lawyer, a specialist. “The big problem is the social demand for homework, video games and friends. Teens don’t understand how important sleep is.”
Rebecca Lucas, another teacher agrees. “Teens are busy,” she said, noting many activities most teens are involved in during the day force them to get home pretty late.” When I see teens sleeping in my class, I feel sad, like they are not sleeping enough,” she said. “I also feel frustrated because I have so much to teach in such a short amount of time and teens sleeping in the class slows me down.”
Not sleeping the needed number of hours can affect your day very much. The effect is on school, work and driving and is very frustrating to teachers when students don’t do their best because of being so tired, Lawyer said.
Al Taylor, a teacher says sleeping is not allowed in his class. “When I see a teen sleeping in my class, I feel bad that they didn’t get enough sleep but they need to correct the issue at home,” Taylor said. “I’ve raised teenage boys myself. Teenagers like to wait to the last minute to do their homework so they often stay up late trying to finish it.”
72. What does Shelly first do when she finds students sleeping in class?
A. She wakes them up with no punishment.
B. She blames herself for giving a boring lesson.

根據(jù)短文內(nèi)容，從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)，選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。
In many parts of the world, cars play an important role in daily life and many societies would not exist without them.  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.  2  That will mean much saving, no accidents and better use of roads. The super-intelligent car in the future will drive itself.  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.  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.  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.
