Astronauts on shorter shuttle missions often work very long days. Tasks are scheduled so tightly that break times are often used to finish the day's work. This type of schedule is far too demanding for long missions on the International Space Station (ISS). ISS crewmembers usually live in space for at least a quarter of a year. They work five days on and two days off to mimic the normal way they do things on Earth as much as possible. Weekends give the crew valuable time to rest and do a few hours of housework. They can communicate with family and friends by email, internet phone and through private video conferences.
While astronauts cannot go to a baseball game or a movie in orbit, there are many familiar activities that they can still enjoy. Before a mission, the family and friends of each ISS crewmember put together a collection of family photos, messages, videos and reading material for the astronauts to look at when they will be floating 370 kilometers above the Earth. During their mission, the crew also receives care packages with CDs, books, magazines, photos and letters. And as from early 2010, the internet became available on the ISS, giving astronauts the chance to do some "web surfing" in their personal time. Besides relaxing with these more common entertainments, astronauts can simply enjoy the experience of living in space.
Many astronauts say that one of the most relaxing things to do in space is to look out the window and stare at the universe and the Earth. Both the shuttle and the ISS circle the planet several times each day, and every moment offers a new view of the Earth's vast land mass and oceans.
What does the word "mimic" in Paragraph 1 probably mean?

A．copy

B．find

C．change

D．lose

Which of the following best describes the families of the astronauts on the ISS?

A．They are impatient and annoyed.	B．They are worried and upset.
C．They are caring and thoughtful.	D．They are excited and curious.

In the final paragraph, the author shows that astronauts ________.

A．love to see the Earth from space	B．find living in space a bit boring and tiring
C．regard space life as common	D．get more pleasure in space than on the Earth

The passage mainly discusses how astronauts ________.

A．work for longer missions in space	B．spend their free time in space
C．observe the Earth from space	D．connect with people on the Earth

Many people think the search for cleaner energy leads only to renewable resources like sun, wind and water. But it also leads to a fossil fuel. Natural gas is considered the cleanest of the fossil fuels, the fuel created by plant and animal remains over millions of years. Burning it releases fewer pollutants than oil or coal. The gas is mainly methane (甲烷). It produces half the carbon dioxide of other fossil fuels. So it may help cut the production of carbon gases linked to climate change.
Russia is first in what are called "proved reserves" of natural gas. The United States is sixth. Over the years, big oil and gas companies recovered much of the easily reached supplies of gas in America. They drilled straight down into formations where gas collects. As these supplies were used up, big drillers looked for similar formations in other countries.
But now the industry is taking a new look. Companies are developing gas supplies trapped in shale (页岩) rock two to three thousand meters underground. They drill down to the shale, then go sideways and inject high-pressure water, sand or other material into the rock. This causes the rock to fracture, releasing the gas. Huge fields of gas shale are believed to lie under the Appalachian Mountains, Michigan and the south-central states. Gas shale exploration is being done mainly by small to medium sized companies. Eric Potter, a program director, says more than half the gas in the United States is now coming from these new reserves.
But hydraulic (液压的) fracturing can also produce debate and anger over the risk of groundwater pollution. This method of drilling is not federally supervised under the Safe Drinking Water Act. Some in Congress want to end that exemption (豁免) from the law.
Natural gas provides Americans with about one fourth of their energy. And, unlike oil, most of it is produced in America. Gas producers invested heavily in reaching new supplies when prices were high. But prices are down sharply now because the depression cut demand for energy. So energy expert Eric Potter says it is too early to know how the changing market prices will affect the market for gas shale exploration.
1. We can learn from the first paragraph that ________.
A. natural gas releases methane and carbon dioxide
B. natural gas is considered as the cleanest energy
C. natural gas is more environmentally friendly than other fossil fuels
D. natural gas is a renewable source of energy
2. The word “fracture” in Paragraph 3 probably means ________.
A. create                           B. break                    C. change                   D. decrease
3. Gas shale exploration may cause disagreement because ________.
A. it may cause water pollution                               B. it brings too high profits
C. it breaks the law                                         D. it is out of states’ control
4. According to Eric Potter, the new gas shale exploration ________.
A. will provide America with about one fourth of their energy
B. will increase demand for energy
C. will make gas producers invest a big sum of money
D. may be influenced by the changing market prices

As I was reading a recent story in Slate on 20-somethings complaining about how the economy was ruining their life plans, I couldn’t help but think the 20-somethings sounded like a bunch of spoiled children who grew up expecting everything to be easy for them. As a 20-something myself, I certainly share their disappointment: my husband and I probably won’t be able to buy a house until we’re in our 40s, and we too are burdened by student loans(贷款). But why should it be any different? Being young persons in America, shouldn’t they take up all of the challenges and opportunities that this country offers?
Consider some of these views shared in the Slate story: Jennifer, 29, owner of a two-bedroom apartment with her husband, worries that she won’t be able to have children for at least a decade because they can’t afford to buy a house yet.
I read that, and I thought, what planet is she living on where you need to own a house in order to have kids? Has she ever visited a developing country, or even downtown areas in this one? Home ownership is a luxury(奢华), not a fertility requirement.
A 26-year-old in the story despairs(绝望) that he can’t afford to get a Ph.D. in literature. Well, that sounds a bit like expressing disappointment that no one will pay you to write poetry on the beach in Thailand for five years.
Yes, it’s sad that these young people feel so lost. But I think the problem is their extremely high expectations, not economic reality. Beth Kobliner, author of Get a Financial Life: Personal Finance in Your Twenties and Thirties, says that she thinks people’s expectations are slowly adjusting, but today’s 20-somethings grew up at a time when everyone’s wealth appeared to be expanding. Their parents probably saw their home values rise along with their investments. “So you have people who have grown up in an environment where people had great expectations of what living well means,” says Kobliner.
This recession(衰退) will certainly play a role in forcing those expectations into more realistic group. In the meantime, it seems a lot better for our mental health to focus on being grateful－for our one-bedroom apartments, for living in modern cities, or perhaps just for being able to eat three meals a day－than on longing for some kind of luxury life.
1. What makes the author think the 20-somethings sound like a bunch of spoiled children?
A. They expect everything to be easy for them.
B. They complain that the economy is spoiling their life plans.
C. They are reluctant to face all of the challenges.
D. They are burdened by student loans.
2. The underlined word “fertility” in Paragraph 3 probably means ________.
A. baby production        B. pleasant                    C. baby comfort            D. essential
3. What’s the author’s attitude towards the 20-somthings with high expectation in Paragraph 5?
A. Intolerant.             B. Negative.              C. Unbelieving.                D. Understanding.
4. What is the best title for this passage?
A. How Young People Afford to Continue Their Study
B. Why Young People Can’t Afford to Buy a House
C. When Young People’s High Hopes Create Despair
D. What the 20-somethings’ High Expectations Are

Companies can increase the money with which they run their business in a number of ways. One way is borrowing money, and another way is buying things with the agreement that payment would be made later. There are also other processes for providing money for use by a company. Two of these processes are described here.
One process the company may use is to issue bonds(债券). Bonds are a special kind of promissory note. They are issued in different values, in the forms of money used in different countries, such as the pound in England or the euro in Europe. These bonds can easily be sold again to other people or to other companies. The company that issues the bonds promises to pay a particular amount of money as interest regularly for a certain period of time. This continues until when the company has to pay back the principal(本金) of the bond. Payments of principal and interest must be made on time whether the company has been earning money or not. If these payments are not made on time, it means that the company has not done what it agreed to do and can be sued(控告，起诉).
Another process companies may use is to issue other forms of promissory notes called stocks(股票). Bonds and stocks are opposite methods of providing money for a company. The people who buy stocks provide money that is earned and take part in deciding how the company will conduct its business. They must also take part in the losses. The people who own stocks receive dividends only after the company has paid all of its debts to the people who own bonds. On the other hand, the persons who own bonds have no right, according to the law, to help decide how the company will handle its business, unless it is bankrupt or in danger of becoming so.
1. Which of the following statement is not the way for companies to increase their capital?
A. Borrowing money.                                   B. Buying materials without paying.
C. Issuing bonds                                       D. Issuing stocks
2 As to bonds, we know from the passage that ________.
A. they are cheques like bank notes
B. the company only pays back the principal
C. they are issued in the forms of money
D. if a company is bankrupt, it needn’t pay back the interest
3. According to this passage, who have the legal control over the decisions of the business?
A. Stockholders                                          B. Bondholders
C. The government                                       D. The workers in the company
4. It can be inferred from this passage that ________.
A. to issue bonds is a better way than to issue stocks
B. stockholders can sue the company when it is bankrupt
C. bondholders have the same rights as stockholders
D. investing in stocks has more risk than in bonds

第三部分：阅读理解（共20小题，每小题2分，满分40分）
As China’s women’s gymnastics team enjoyed the glory of winning the country’s first team Olympic gold medal at the 2008 Beijing Olympic Games，the young gymnasts took the opportunity to remind the world that they are old enough to compete．
Weeks before the Beijing Games, some international media raised questions about the ages of some of the members of China’s gymnastics team, particularly He Kexin and Jiang Yuyuan. They said the girls might be younger than 16, the minimum age for the Olympics. But the Chinese Gymnastics Association quickly provided copies of the gymnasts’ ID cards and passports, proving they are indeed old enough to compete.
In the final, He Kexin gave a clean performance on her favorite uneven bars（高低杠）, earning the second highest score after falling from the bars during qualification. “Although I fell down in the qualification, I became more confident today to make up for my mistake and I finally made it.”She said. It was a great moment for head coach Lu Shanzhen. “Our team made history today and proved to the world that we are the best.” the coach said, “The gold medal is not only for the gymnastics team，but also for the whole Chinese delegation at the Beijing Games.”
The coach owed the team’s success to a series of reforms. The Chinese team used to train a 1ot, but competed less, which led to poor results in international competitions. To improve their ability to compete and to strengthen their psychological power, the Chinese team sent more team members to compete abroad, so they could bring a competitive spirit back to the team. All six gymnasts in the Olympic team final were selected from fierce competition, and they proved themselves today.
1. Before the Beijing Games started，some international media doubted whether ________.
A. Chinese women gymnasts could win the team gold medal
B. He Kexin would fall from the bars during qualification
C. Chinese women gymnasts could make history at the Beijing Games
D. some Chinese women gymnasts were old enough for the Games
2. Which of the following statements is NOT true?
A. The international media’s doubts proved to be true.
B. He Kexin’s fall in the qualification had no bad effect on her performance in the final competition.
C. Chinese women gymnasts’ success at the Beijing Games proved that the reforms did work.
D. Each team is made up of 6 members to compete for the team gold medal in women gymnastics.
3. In the opinion of Lu Shanzhen, the key to achieving success for athletes is to________.
A. practice harder than ever                    B. experience more competitions abroad
C. have strong psychological power                    D. have a competitive spirit
4. The main purpose of the text is to________.
A. tell a story     B. provide evidence           C. give a report            D. compare opinions
