The cheetah(猎豹)is best known for being the world’s fastest land animal, reaching speeds of just over 110kph for short period of time. However, many people know little else about this wonderful animal. The word cheetah probably comes from a Hindi word spotted animal. It is very similar to other cats but also has some obvious differences. Its body is much leaner than most cats and it has much longer legs.
People sometimes make a cheetah a leopard(美洲豹)because they both have spots, but in fact they are very different. A leopard is far heavier and more powerful, but also much slower. The cheetah’s spots cover most of its body except for its stomach and throat. The cheetah’s tail has spots and these become rings at the end of the tail.
An adult cheetah weighs between 35-65 kilograms and is about 80 centimeters high at the shoulder. The cheetah’s head is quite small and the eyes are quite high up. A black line runs from each eye down to its mouth and makes it look a little sad. It has high shoulders that help it to walk so gracefully.
Cheetahs are very fast but they are not very strong. They are not good fighters and will run away rather than fight another animal to protect their food. If they make a kill, it is sometimes taken away from them by stronger animals such as lions and leopard. These animals will kill their young if they get the chance. The cheetah is not a threat to humans at all. It will not attack humans and prefers to stay away from occupied areas.

Nuclear energy has always been controversial. But since the tsunami and nuclear disaster in Fukushima (Japan) last year the issue is back in the headlines. And the world is divided— some countries are planning more nuclear plants, while others have promised to shut theirs down.
After Fukushima, Germany decided to switch off all its nuclear plants by 2022. Switzerland and Italy are also phasing out nuclear power. But France and the United States remain staunch supporters of atomic energy. In fact, almost 80% of France’s electricity comes from nuclear power, the highest percentage in the world. And in the US, the Obama administration said it “continues to support the expansion of nuclear power, despite the crisis in Japan.”
Nuclear supporters claim nuclear power can help the environment. Unlike fossil fuels, nuclear power doesn’t create greenhouse gases. So, pro-nuclear countries argue that nuclear power allows them to generate energy without contributing to climate change. Britain’s chief scientific adviser (John Beddington) supports this view. He recently said that the world doesn’t have the luxury of ignoring nuclear energy.
Nuclear power is also relatively cheap. Renewable energy sources such as solar, hydro and wind power may be clean, but they’re expensive; and right now, they require a lot of investment. This higher cost of using “green energy” is usually passed onto the consumer. So, while many people may prefer their energy to come from a renewable source, not so many are prepared to pay higher energy bills. This is of particular concern while the world economy is in such bad shape.
The main argument against nuclear energy is that it isn’t safe. For a start, nuclear waste is very difficult to dispose of, and remains toxic to humans for thousands of years. And even before Fukushima, there were several high-profile nuclear disasters. The most famous is probably the 1986 Chernobyl disaster, in the Ukraine. The radiation from the meltdown spread all over Europe, affecting thousands.
The nuclear energy issue is very complex. And it doesn’t look like it’ll be resolved anytime soon. As a Japanese commentator recently said, “it’s been a bad year for the ‘nuclear village’, but I don’t think they’re down and out yet.” The battle continues.
小题1:Which of the following may NOT be the advantage of nuclear energy over other energy sources?

A．Nuclear energy doesn’t produce any greenhouse gases.

B．Nuclear energy can help prevent the climate damage.

C．Nuclear energy is more environmental-friendly than other green energy sources.

D．Nuclear energy can save the consumers some money, compared to other renewable energies.

小题2:What does the underlined word “this” refer to in paragraph 4?

A．The fact that many people prefer to use the green energy sources while unwilling to pay higher bill.

B．The cost of using renewable sources

C．The fact that the nuclear power is cheaper.

D．The investment of renewable energy sources

小题3:We can learn from the last paragraph that _______.

A．the Japanese commentator is positive about the future of nuclear energy

B．the nuclear energy issue will be soon settled

C．a battle will break out in the future

D．Japan is considering to build a nuclear village in the future

小题4:What is the author’s purpose of writing the passage?

A．To highlight the danger of using nuclear energy.

B．To introduce some serious nuclear disasters.

C．To show the argument between nuclear supporters and protesters.

D．To give some advice on how to use nuclear energy safely.

American beekeeping operations have been hit hard by what scientists call colony collapse disorder(C.C.D.). Almost half of their worker bees have disappeared during the past season. C.C.D. has also been reported in Israel, Europe and South America. Bees fly away from the hive and never return. Sometimes they are found dead; other times they are never found. Many crops and trees depend on pollination （授粉） by bees to help them grow.
A new report says virus may be at least partly responsible for the disorder in honey bee colonies in the United States. This virus is called Israeli acute paralysis virus. It was first identified in Israel in 2004. Ian Lipkin at Columbia University in New York and a team reported the new findings in Science magazine. Doctor Lipkin says the virus may not be the only cause. He says it may work with other causes to produce the collapse disorder.
The team found the virus in colonies with the help of a map of honey bee genes that was published last year. They examined thirty colonies affected by the disorder. They found evidence of the virus in twenty–five of them, and in one healthy colony. The next step is further testing of healthy hives.
The researchers suggested that the United States may have imported the disorder in bees from Australia. They say the bees may carry the virus but not be affected.
The idea is that unlike many American bees, the ability of Australian bees to fight disease has not been hurt by the varroa mite（全球性的蜂虱）. This insect attacks honey bees, which could make the disorder more likely to affect a hive. Australian bee producers reject these suspicions.
And some researchers suspect that bee production in the United States is down mainly because of the weather. Honey bees gather nectar（花蜜） from flowers and trees. The sweet liquid gives them food and material to make honey. But cold weather this spring in the Midwest reduced the flow of nectar in many flowers. Many bees may have starved. Dry weather in areas of the country could also be playing a part.
Wayne Esaias is a NASA space agency scientist who keeps bees in his free time. He lives in central Maryland, where he has found that flowers are blooming a month earlier than they did in 1970, which may be partly responsible for the disorder. Wayne Esaias is organizing a group of beekeepers to document nectar flow around the country.
小题1:The researchers found the virus ______.

A．with the help of colony collapse disorder

B．by researching the causes of bee death

C．with the help of a map of honey bee genes

D．with the help of a scientist of NASA

小题2:What is the passage mainly about?

A．American beekeeping industry has been strongly influenced by the bee disorder.

B．Studies are being carried out on the causes of the bee disorder, but questions remain.

C．How the causes of the bee disorder in U.S have been found.

D．The bee production in U.S is down because of Israeli acute paralysis virus.

小题3:How many possibilities may be involved in the bee disorder according to the passage?

A．Three.

B．Four.

C．Five.

D．Six.

小题4:We can infer from the passage that ______.

A．Israeli acute paralysis virus should be responsible for the disorder

B．the solution to the bee disorder will be found eventually

C．American bees are more likely to defend themselves than Australian bees

D．the crop and plant production in U.S may be influenced by the bee disorder

Imagine, one day, getting out of bed in Beijing and being at your office in Shanghai in only a couple of hours, and then, after a full day of work, going back home to Beijing and having dinner there.
Sounds unusual, doesn"t it? But it"s not that unrealistic, with the development of China’s high—speed railway system. And that’s not all. China has an even greater high-speed railway plan—to connect the country with Southeast Asia, and eventually Eastern Europe.
China is negotiating to extend its own high·-speed railway network to up to 17 countries in 10 to 15 years, eventually reaching London and Singapore.
China has proposed three such projects. The first would possibly connect Kunming with Singapore via Vietnam and Malaysia. Another could start in Urumqi and go through Kazakhstan and Uzbekistan, and possibly to Germany. The third would start in the northeast and go north through Russia and then into Western Europe.
If China’s plan for the high-speed railway goes forward, people could zip over from London to Berlin in under two days.
The new system would still follow China’s high-speed railway standard. And the trains would be able to go 346 kilometers an hour, almost as fast as some airplanes.
China’s bullet train(高速客车),the one connecting Wuhan to Guangzhou, already has the World’s fastest average speed. It covers 1,069 kilometers in about three hours.
Of course, there are some technical challenges to overcome. There are so many issues that need to be settled, such as safety, rail gauge(轨距),maintenance of railway tracks. So, it’s important to pay attention to every detail.
But the key issue is really money. China is already spending hundreds of billions of yuan on domestic railway expansion.
China prefers that the other countries pay in natural resources rather than with capital investment. Resources from those countries could stream into China to sustain development.
It’ll be a win-win project. For other countries, the railway network will definitely create more opportunities for business, tourism and so on, not to mention the better communication among those countries.
For China, such a project would not only connect it with the rest of Asia and bring some much-needed resources, but would also help develop China’s far west. We foresee that in the coming decades, millions of people will migrate to the western regions, where the land is empty and resources unused. With high-speed trains, people will set up factories and business centers in the west once and for all. And they’11 trade with Central Asian and Eastern European countries.
小题1:China’s new high-speed railway plan will be a win-win project because .

A．China will get much-needed resources and develop its western regions

B．China and the countries involved will benefit from the project in various ways

C．China will develop its railway system and communication with other countries

D．the foreign countries involved will develop their railway transportation, business and tourism

小题2:According to the passage, the greatest challenge to the new high-speed railway plan is .

A．technical issues

B．safety of the system

C．financial problems

D．maintenance of railway tracks

小题3:Which of the following words best describes the author’s attitude towards China’s high-speed railway plan?

A．Critical.

B．Reserved.

C．Doubtful

D．Positive.

小题4:Which of the following might be the best title for the passage?

A．New Railway Standards

B．Big Railway Dreams

C．High-speed Bullet Trains

D．International Railway Network

Everyone is at it, even my neighbors. I thought I might be the only person left in the world who hadn’t done an eBay deal. So, I decided to try my hand at online auction (网上拍卖).
Buying for beginners: Sign up on www. ebay. co. uk. Most items（e.g. tables, computers, and books）ready for auction will come with a picture and a short description; others may be marked with “ Buy It Now ” and have a fixed price. You can buy these right away.
If the item is being auctioned, you offer the highest price you are prepared to pay and eBay bids（出价）for you. The bid will be increased little by little until it goes beyond your highest bid, then you are emailed and asked if you would like to bid again. Auctions last up to 10 days and when they finish you get an email telling you whether you have won the item.
How to pay: Sellers decide how they would like to be paid and you need to check this before placing a bid as you might not want to post a check or postal orders. The easiest way is through PayPal, an online payment system that takes the money away from your credit card (信用卡).
Selling made simple: If you plan to sell on eBay, it helps to include a picture of the item. I followed my friends’ advice and put up the items I wanted to sell for a 10-day auction, starting on a Thursday. This way buyers had two weekends to bid.
The big things in life: It’s easy to post a small item, but furniture is a big part of eBay and this has to be collected or sent by delivery men. Check the ways of delivery before you bid.
小题1:What is the passage mainly about?

A．How to make payment online.

B．Ways of using delivery online.

C．Advantages of an online-auction system.

D．How to use an online-auction system.

United States and Canada are multicultural countries with many national, religious and cultural differences, where people attach great importance to individualism—the uniqueness among people. Teachers value the qualities that make each student special and different. You can see such values through their educational systems. For example, students needn’t memorize lots of information. Instead, they work independently and find answers on their own. There are discussions for children to show their own ideas and opinions.
By contrast, people have the same language, history, and culture in most Asian societies. As a result, Asia’s educational system reflects society’s belief in group goals and purposes rather than individualism. Children in China, Japan, and Korea learn to work together and help one another in assignments. And the teaching methods are often very formal and serious. In class, teachers give lectures while students listen and take notes. Discussion is replaced by reciting rules of information that have been memorized.
These two systems both have advantages and disadvantages. One advantage in Japan is that there is much more math and science than American students learn by the end of high school. In addition, students study more hours each day and more days each year than North Americans do. The difficult system also prepares students for a society that place emphasis on discipline and self-control. However, while memorization is an important learning method in Japanese schools, yet many students admit forgetting much of the information that they have memorized after exams.
On the other hand, the educational system in North American has an advantage that students learn to think for themselves, which prepares them for a society that values creativity. The disadvantage is that when they graduate from high school, they haven’t recited as many basic rules and facts as students in other countries have.
小题1:People in multicultural countries such as the US or Canada lay more stress on __________.

A．team work

B．self-control

C．discipline

D．individualism

小题2:What is the advantage of the educational system in North America？

A．There is not much discussion.

B．Learning to think for themselves

C．Learning much less math and science

D．They haven’t memorized basic rules and facts.

小题3:Which words is most suitable to describe the author"s attitude in writing this passage?

A．Supportive

B．Opposite

C．Objective

D．Subjective

小题4:The main idea of this passage is___________.

A．cultural differences in countries such as the United States or Canada

B．comparisons of educational system between North America and Asia

C．there are more advantages of Asian education system of than that of North American

D．there are more disadvantages of Asian education system than that of North American
