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．

When most people think of giant pandas, the pictures of the cute, black-and-white bears from China that eat bamboo will immediately jump into their mind. Scientists from Mississippi State University, however, are interested in what they leave behind: their poop(排泄物). At a recent meeting in Denver, Professor Brown at the university presented her research showing how panda poop could inspire a new way to obtain energy from plants, which are a renewable energy source. Usually, plants can be called biomass(有机燃料) when they are used as an energy source.

Burning biomass is one way to capture its energy, but Brown hopes panda poop can teach scientists something about breaking down biomass. Pandas—or at least the bacteria in their stomachs—are very good at getting energy out of bamboo. Unlike cows, which use 4 stomachs to digest large amounts of grass, a panda has only one stomach. Bamboo comes in, and poop goes out.

Every day for 14 months, Brown and her team on this project, counted the bacteria in the poop of the two pandas, YaYa and LeLe living at the Memphis Zoo. Her studies turned up 12 species of bacteria that break down biomass, including one that had never been found in pandas. Brown says that because the poop contains bacteria that break down biomass, it could also be used to break down other types of biomass.

Now the scientists hope to identify the chemicals that help with the process of breaking down biomass and then figure out how the bacteria work. If those chemicals can be made in the lab, they could be used to turn biomass—like grass or other plants—into fuel.

Brown says she doesn’t mind handling panda poop. “It’s probably the most pleasant material to work with,” she says, “My colleagues and I have been working with other poop for a long time, and we can assure you it has a fairly pleasant smell associated with it.”

1.The importance of studying panda poop is _______.

A. to create a renewable energy from plants

B. to explore a new way to get energy from plants

C. to learn a lesson of energy from panda poop

D. to figure out how the bacteria work for us mankind

2.The process of the panda poop project can be described as ______.

A. a, b, d, c           B. a, d, c, b           C. b, a, d, c           D. b, d, a, c

3.What does the author mainly want to express in the 2nd paragraph?

A. Pandas don’t digest bamboo the same way as cows.

B. Pandas are capable of getting energy using stomachs.

C. Pandas can get energy from bamboo more efficiently.

D. Scientists have learnt something new from panda poop.

4.What does Professor Brown think of working with panda poop?

A. Sick             B. Challenging          C. Inspiring            D. Enjoyable

BAD weather, bad food and grumpy people – that’s what some people think of first when they think about Britain. Many online commentators even joke that Britons are so grumpy precisely because it constantly rains and they are always hungry.

In fact, many believe that Britons are inherently negative, in contrast to their neighbors across the Atlantic Ocean.

“Americans are more optimistic, due to the fact that they are told they can become the next president of the United States,” Ricky Gervais, a British comedian, told online forum Big Think. “British people are told, it won’t happen to you. And they carry that. They carry that with them. We champion the underdog .”

It’s no wonder that Britons hold the reputation of having a “stiff upper lip” – being cold and not showing any emotion.

Britain’s reputation as a grumpy country may, however, simply be the result of a cultural misunderstanding. According to the BBC, British actor Michael Caine once said: “I think what is British about me is my feelings and awareness of others and their situations. English people are always known to be well-mannered and cold, but we are not cold – we don’t interfere in your situation. If we are heartbroken, we don’t scream in your face with tears – we go home and cry on our own. It’s completely to do with your comfort – we don’t intrude on your space. That’s very English.”

A BBC reader noted that the perceived coldness of British people is actually their way of dealing with hardship. Remembering the terrorist attacks in London on July 7, 2005, Stuart Colley, who lived in the capital at the time, said: “It seemed to me that most people’s response was a ‘cruel’ determination to carry on and not to ‘fall’ into an over-emotional outpouring of grief or anger – despite what many of us felt inside. Our stiff upper lip seems to be something that gives us strength as a society when we most need it.”

1.What is the author’s main purpose in writing the article?

A. To list common stereotypes about the UK.

B. To fight common misunderstandings about the UK.

C. To analyze what makes British people grumpy and negative.

D. To list some differences between Americans and British people.

2.Which of the following statements might Ricky Gervais agree with?

A. Britons like challenging the underdog more than Americans do.

B. Americans are more optimistic and realistic than British people.

C. Britons are more comfortable with life’s losers than Americans.

D. Bad weather in the UK is the main thing that makes Britons grumpy.

3.The underlined phrase “interfere in” in the second-to-last paragraph is closest in meaning to ______.

A. think about　 B. benefit from

C. get in the way of D. have a positive effect on

4. Why does Michael Caine think British people are not cold?

A. They can be heartbroken, and they cry too.

B. They are well-mannered and unwilling to disturb others.

C. They care a lot about what other people think of them.

D. They are taught to face hardships by themselves.

5.With the example of the terrorist attacks in London on July 7, 2005, the author intends to ____.

A. explain why British people tend to be cold

B. reveal that Britons don’t intrude on others’ space

C. present an example in which British people hide their emotions and feelings
