Satellites are an important part of our ordinary lives．For example, the information for weather forecasts is sent by satellite．Some satellites have cameras which take photographs of the Earth to show how clouds are moving．Satellites are also used to connect our international phone calls．
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．

Bowing is a very important custom in Japan. Unlike people in many other countries, they greet each other by bowing instead of shaking hands. It is impolite not to return a bow to whoever bows to you.
Bowing has many functions in one. It expresses the feeling of respect, thanks, regret, and so on. You can bow when you say, “thank you”, “sorry”, “hello”, “goodbye”, “congratulations”, “excuse me”, “good morning”, and more.
Bowing seems simple, but there are different ways of bowing. Bowing techniques vary from a small nod of the head to a long, 90-degree bow. It depends on the social position or age of the person you bow to. If your opposite is of higher social position or older than yourself, you are supposed to bow deeper and longer than him or her. It is polite to bow from your waist. Men usually keep their hands at their sides, and women usually put their hands together on their legs with their fingers touching. If it is not a very formal situation, you can bow by nodding. The most common bow is a bow of about 15 degrees.

When Paul was a boy growing up in Utah, he happened to live near a copper smelter(炼铜厂), and the chemicals that poured out had made a wasteland out of what used to be a beautiful forest. One day a young visitor looked at this wasteland and called it an awful area. Paul knocked him down. From then on, something happened inside him.
Years later Paul was back in the area, and he went to the smelter office. He asked if they had any plans or if they would let him try to bring the trees back. The answer from that big industry was “No.”
Paul then went to college to study the science of plants. Unfortunately, his teachers said there weren't any birds or squirrels to spread the seeds. It would be a waste of his life to try to do it. He was told everyone knew that even if he was knowledgeable as he had expected, he wouldn't get his idea accepted.
Paul later got married and had some kids. But, his dream would not die. And then one night he did what he could with what he had. Under the cover of darkness, he went secretly into the wasteland and started planting.
And every week, he made his secret journey into the wasteland and planted trees and grass. For fifteen years he did this against the plain common sense. Slowly rabbits appeared. Later, as there was legal pressure to clean up the environment, the company actually hired Paul to do what he was already doing.

Commencement (毕业典礼) is a time for idealism.
But economic reality is cruel everywhere; especially for new graduate. They have been told repeatedly that a college degree is an open sesame(芝麻) to the global economy. But that’s not necessarily so, according to new research by two economists at he Massachusetts Institute of Technology, Frank Levy and Peter Temin.
It is true that people with college degrees make more money than people without degrees. The gap has narrowed somewhat in recent years, which is disturbing. But the earning power of college graduates still far outpaces that of less-educated workers.
The bad news, though, is that a college degree does not ensure a bigger share of the economics pie for many graduates. In recent decades Mr. Levy and Mr. Temin show, only college-educated women have seen their income grow in line with economy wide gains in productivity. The earnings of male college graduates have failed to keep pace with productivity gains.
Instead, a huge share of productivity growth, which expands the nation’s income, is going to Americans on the top of the income scale. In 2005, the latest year with available data, the top of 1 percent of Americans---whose average annual income was $ 1.1 million--- took in 21.8 percent of the nation’s income, their largest share since 1929.
Administration officials, and other politicians and economists, often, believe that income inequality, reflects an education gap. But Mr. Levy and Mr. Temin show that in the case of men, the average bachelor’s degree is not enough to catch the rising tide of the global economy.
They argue that the real reason that inequality is worsening is the lack of strong policies that broadly distribute economic gains. In the past, for example, a more progressive income tax and unions promote equality. Positive measures have been eroding and new ones have not yet emerged, making the income gap even greater.
Mr. Levy and Mr. Temin conclude that only a new government policy can restore general prosperity. That’s a challenge to the nation’s leader and today’s graduates. America needs them to contribute to the development of the nation in global economy.The passage is mainly about that _______.
| A．there is a big income gap between female and male college graduates in America. |
| B．college graduates find it hard to find an ideal job after graduation in America. |
| C．research shows that American government should take measures to ensure income equality for college graduates |
| D．college degrees are losing value in America. |
What is the main idea of paragraph 5?
| A．The whole nation has enjoyed a big income growth with the growth of productivity. |
| B．Much of the total income in America has been gained by a few very rich people. |
| C．A small part of people in America have income increase. |
| D．Upper class Americans contribute most to productivity growth. |
The underlined word “eroding” in paragraph 7 probably means _______.
| A．being gradually destroyed by wind or rain |
| B．gradually reducing power |
| C．gradually disappearing |
| D．gradually not suitable |
We can infer from the passage that _______.
| A．female college graduates have higher income than male ones. |
| B．female college graduates have benefited from some governmental measures to ensure their income growth. |
| C．income tax can grantee income equality. |
| D．new measures and policies have been taken to promote income equality. |
From the passage, some economists believe that the worsening income inequality is caused by ______.

The name “cowboy” conjures up many different images from movies, songs and TV. These imagined cowboys range from white-hat-wearing heroes to gun-shooting hooligans(流氓).But, cowboys are actually real people from US history.
When the US Civil War ended, many soldiers had no place to call home. So, they began to drift to the country’s rural West. Ranchers(农场主) hired these men to take care of the cattle and work around the ranch. When the ranch owner wanted to sell the cattle, the cowboys would round up the herd from the open prairie(牧场) and drive the cattle miles to the market.
With the invention of barbed wire(铁丝网),the cowboy era(1865-1890) began to come to an end. But people in the East had always been curious about their lifestyle. Many country/western songs during this time tried to capture the true cowboy spirit. Newspapers published cowboy tales in serial form and adventure novels followed. The bigger the fiction, the better the sales. These novels often portrayed cowboys as cruel and violent men. Cowboys carried the bad reputation for many years afterwards.
When movies began to be popular in the 1920s, the cowboy image changed again. Now, a cowboy became the great white knight(骑士) that loved his horse more than the beautiful ladies he rescued. As the cowboy of the “Old West” spent more time with his horse than the ladies, this era's image was not entirely false.
Then, in the 50s,Hollywood began producing so-called “spaghetti westerns(意大利西部片)”.They earned the nickname because Italian companies financed the films and TV shows. This started the decade’s “Cowboy Craze”. While this didn’t last long, it made modern country / western music, fashion and dance extremely popular.
In recent years, with the help of musicians, radio stations and bars, cowboy nostalgia(怀旧情绪) has returned. Even though his image is still changing — somewhere between ballad singing country boy and bar room fighter — there’s one thing for sure, you can’t keep the cowboy down.The purpose of this story is to ______.
| A．introduce cowboy movies and novels |

| B．the distant Wild West appealed to people in the East |
