Computer connections of the World Wide Web and Internet also use satellites. Many of our TV programs come to US through satellites.Airplane pilots also sometimes use a satellite to help them find their exact location.
We use satellites to send television pictures from one part of the world to another.They are usually 35,880 kilometers above the equator.Sometimes we can see a satellite in the sky and it seems to stay in the same place.This is because it is moving around the world at 11,000 kilometers an hour—exactly the same speed that the earth rotates.A satellite must orbit the Earth with its antennae(天线)facing the earth.Sometimes, it moves away from its orbit,So there are little rockets on it which are used to put the satellite back in the right position.This usually happens about every five or six days.
Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth.A satellite usually works for about 10-12 years.Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired.Often,very old or broken satellites are left in space to orbit the Earth for a very long time.This is very serious because some satellites use nuclear power and they can crash into each other.
56.Which of the following is NOT done by satellites according to the passage?
A.Sending information for weather forecast.
B.Taking photographs of the Earth.
C.Sending TV pictures.
D.Providing food for airplane pilots.
57.What’s the speed the earth rotates at?
A.35,880 kilometers per hour. B.335,880 kilometers per hour.
C.11,000 kilometers per hour. D.110,000 kilometers per hour
58.Why does the satellite move around the world at the same speed as the Earth rotates?
A.In order to take photographs.
B.In order to stay in a certain position in the orbit.
C.In order to move away from its orbit.
D.In order to send television pictures.
59.What does the underlined word “This” refer to?
A.A satellite. B.A little rocket.
C.A satellite seems to stay in the same place in the sky.
D.The satellite puts the rockets in the right position.
60.Which is true of satellites?
A.A satellite usually works for about 10-2 years.
B.Every time a satellite gets broken,it is brought back to the Earth to be repaired.
C.A broken satellite is never left in space.

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(种子). 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.

There used to be an old joke in America that people should take a bath once a week, whether they need one or not. In fact, though, Americans generally take a bath or more commonly, a shower every day. But in contrast to some cultures, most Americans get their shower in the morning so that they can start the day fresh. Americans are known for having very sensitive noses. In America, body smell is socially unacceptable. For that reason, Americans consider it a must to use special lotion (浴液) to prevent the smell. Ladies often add a touch of perfume. Men may spray on after – shave cream or manly – smelling perfume.
Some of the cultural varieties in neatness practices result from physical differences between races. Whereas many Asian men have little facial hair, Westerners have a lot. As a result, most American men spend some time each day shaving or tidying their facial hair to keep it nice. American women, on the other hand, generally prefer not to be hairy at all.
Americans put great value on both neatness and personal cleanness. For some people, taking care of themselves has become almost a religion. As the old saying goes, “Cleanness is next to godliness.” Whether or not being clean and neat – looking brings one closer to God, it certainly at least brings one closer to others. Americans look down on people who don’t take care of themselves, or who “let themselves go.”
68.We can infer from the first paragraph that .
A.everyone takes baths daily to get a nice look.
B.people have the same neatness practices today.
C.neatness practices may be affected by cultures.
D.neatness means combing hair and doing makeup.
69.Americans have a bath in the morning to .
A.begin an energetic day B.refresh their sensitive noses
C.prevent their body smell D.style their hair at home
70.According to the author, physical differences between races can cause differences in .
A.cultures B.locations C.religions D.neatness practice
71.The underlined phrase in the last paragraph means “ ”.
A.care much about themselves B.give loose to themselves
C.stay away from other people D.stay closer to other people

What visual artists like painters want to teach is easy to make out but difficult to explain, because painters translate their experience into shapes and colors, not words. They seem to feel that a certain selection of shapes and colors, out of countless billions possible, is exceptionally interesting for them and worth showing to us. Without their work we should never have noticed these particular shapes and colors, or have felt the delight which they brought to the artist.
Most artists take their shapes and colors from the world of nature and from human bodies in motion (运动) and at rest; their choices show that these aspects (方面) of the world are worth looking at, and that they contain beautiful sights. Modern artists might say that they only choose subjects that provide an interesting pattern, and that there is nothing more in it. Yet they do not choose entirely without reference to the character of their subjects.
If one painter chooses to paint a decaying (腐烂) leg and another a lake in moonlight, each of them is directing out attention to a certain aspect of the world. Each painter is telling us something, showing us something, explaining something – all of which means that he is trying to teach us.
50.According to the passage, all of the following is true except_________.
A.An artist wants to show something meaningful
B.An artist hopes that the public will understand and learn from him
C.An artist asks the public to believe what he says in his work
D.An artist intends to present something that has not been said before
51.It is hard to explain what a painter is saying, because .
A.a painter uses unusual words and phrases
B.a painter uses shapes and colors instead of words
C.most painters do not express themselves well
D.many painters do not say anything
52.Modern artists might say their choice of subject .
A.only provides interesting patterns
B.carries a message to the public
C.has no pattern or form
D.teaches the public important truths
53.The underlined word “exceptionally” in the 2nd paragraph probably means .
A.entirely B.generally C.especially D.usually
