The average American child spends three to five hours a day watching TV. In 1961, the average child began to watch television at age three; however, today it is nine months. Yet, most parents think that television has bad influence on their children. For example, in the early 1970s, my parents believed that my bad eyesight was the result of sitting too close to the screen, and they therefore made my stay at least six feet from it. Today, most people have no such worry, but many new ridiculous（荒谬的）sayings have appeared:
TV makes kids stupid. Many children watch more educational programs when they are pre-schoolers. When they grow up, they can read more books and have much better ideas to solve difficult problems than other children.
TV makes kids violent .The real story is not so simple. Hundreds of studies show that watching violence on TV makes children more aggressive（好斗的）. But a study of over 5,000 children also finds that some positive programs make children kinder. The problem is that kids are increasingly watching shows with violence instead of those suitable for their age.
Sitting around watching TV makes kids overweight. An experiment finds that when children watch less television, they do lose extra weight; however, reducing their television time does not make them more active. The real problem lies in snacking. A widespread habit for kids, and junk-food advertisements.
TV helps kids get to sleep. The opposite is true. The more television children watch, the more likely they are to have irregular sleep and nap patterns. Allowing kids to watch television is part of the problem, not the solution.
1.Which one is the advantage of educational TV programs?
A.They will make children solve difficult problems better than others.
B.They will improve children's ability to get along with others.
C.They are likely to make children more aggressive.
D.They will make sure of children's success in the future.
2.What influence does watching TV have on a child’s sleep?
A.Children are likely to sleep deeper after watching TV.
B.Children's sleep time will be greatly reduced.
C.It will make children form a bad habit of sleeping.
D.Children will go to sleep more easily.
3.What is the purpose of this text?
A.To increase people’s knowledge of watching TV.
B.To warn parents of the disadvantages of watching TV.
C.To explain the bad influences that watching TV has on children.
D.To correct parents’ wrong ideas of television's effect on children.

This is a tale of two friends --- one is blind, the other has no arms. On their own, the two are “disabled”. But together, they are a powerful team that has changed part of their village in North China’s Hebei Province into a rich, green forest. Meet 53-year-old Jia Haixia and Jia Wenqi!
Their story began in 2000, when Haixia, who was already blind in his right eye, lost his left one after an illness. Wenqi lost his arms in an accident when he was just three. Neither
could find a job, so the two decided to team up. They rented some poor land and began to plant trees. In return, the local officials paid them a small fee. Haixia and Wenqi never imagined that they would end up creating an environmental paradise. Their forest now has over 10,000 trees, hundreds of birds and many other wild animals. In addition, it saves the village from river flooding during the rainy season. When the friends work together, they focus on their strengths not their disabilities. Their day begins at 7 a.m. when the sightless Haixia carries Wenqi across the river to get to their worksite. Since they cannot afford to buy young trees to plant, the two use branches from existing trees. Haixia climbs to the tree-top and with Wenqi’s direction, selects the perfect branch. He then digs a hole and carefully plants it. Finally Wenqi waters the area.
Though hard-working, the men don’t make much money. But as Wenqi puts it, “_________________________________”
Neither Haixia nor Wenqi cares about money. Together, they already have everything they need --- a perfect pair of eyes, two strong hands, and the best friendship in the world!
1.Why did Haixia and Wenqi start working together?
A.Haixia needed someone to help him.
B.They both needed a way to make money.
C.They wanted to improve the environment.
D.They were required to do so by local offcials.
2.Haixia and Wenqi’s forest has helped the village by______ .
A.stopping floods in the rainy season
B.increasing the number of tourists
C.making the villagers richer
D.providing more farmland
3.Why do Haixia and Wenqi plant tree branches?
A.They are easy to get.
B.They do not cost money.
C.They can grow very quickly.
D.They are preferred by animals.
4.In paragraph 5, when Wenqi says “We stand on our own feet, so the fruits of our work taste sweeter”, he means that “______”.
A.they hope to make the forest even better
B.the fruits from their trees are very sweet
C.they are proud not to depend on others

Many objects in the universe are invisible,but they send radio waves. The radio telescope thus appeared, and it is considered one of the greatest inventions in the twentieth century. Reber built the world's first radio telescope in 1937. Ryle and Hewish developed radio telescope systems for the location of weak radio sources, and they shared the Nobel Prize for Physics in 1974.
A radio telescope is usually made up of:
One or more antennas to collect the radio waves. Most antennas are made in the shape of a dish to collect and reflect, the radio waves to the sub-reflector, in the same way as a curved mirror focuses visible light to one point.
A receiver and amplifier to receive the radio waves from the sub-reflector, and make these weak radio waves strong enough to be recorded and turned into electronic signals. To make an amplifier sensitive enough, it is usually cooled to, very low temperatures (e. g. as low as -270℃）.
A recorder to keep a record of the electronic signals. Most :radio telescopes today keep the signals to the computer's memory disk for astronomers to analyze later.
Radio wavelengths are much longer than those of visible light, and the radio waves from deep space are always weak. To catch Radio wavelengths are much longer than those of visible light,and the radio waves from deep space are always weak. To catch these waves, radio telescopes usually have huge antennas. The sizes of most antennas in use today are around 50 to 300 metres in diameter. The antenna of FAST in Guizhou, China, the latest and largest radio telescope in the world, is 500 metres in diameter, as large as the size of 30 football fields.
To avoid interferences, and keep the telescopes sensitive, radio telescopes are built in places where there are no human radio waves or electronic signals. For example, FAST is 5 kilometres away from the closest village and 25 kilometres away from the nearest town.
Radio telescopes create pictures of the sky, not in visible light, but in radio waves. This is extremely useful, because there are objects that can't be seen, objects that we wouldn't even know without radio telescopes.
1.Radio telescopes help collect ____________ from the universe
A.light B.objects C.radio waves D.visible signals
2.Most antennas of radio telescopes are made in the shape of a dish to ____________.
A.make the antennas strong enough
B.increase the number of radio waves
C.turn radio waves into electronic signals
D.focus radio waves on the sub-reflector
3.The underlined word "interferences" in the passage refers to __________________.
A.the noises made by villagers and animals
B.the sounds from the radios and televisions
C.the people who go to Guizhou to watch FAST work
D.the radio waves and electronic signals from humans
4.What have we done with the help of radio telescopes?
A.We have received pictures of deep space.
B.We have discovered unknown lives in the universe.
C.We have found some unknown objects in the universe.
D.We have turned the radio waves from space into light.
