题目列表(包括答案和解析)

Most people think of racing when they see greyhounds (灰狗) and believe they need lots of exercise. They can actually be quite lazy! Greyhounds are good at fast races but not long-distance running. They do need regular exercise but they like to run for a short burst and then get back on the bed or a comfortable seat. Another misunderstanding is that greyhounds must be aggressive(好斗的) because they are big in size. In fact greyhounds love people and are gentle with children.

Greyhounds can live for 12 – 14 years but usually only race for two or three years, and after that they make great pets. They don’t need a lot of space, don’t make a lot of noise, and don’t eat a lot for their size.

Normally, greyhounds can be as tall as 90 cm. There is, however, a small-sized greyhound, which stands only 33cm. Greyhounds come in a variety of colors. Grey and yellowish-brown are the most common. Others include black, white, blue, red and brown or a mix of these.

Greyhounds have smooth body coats, low body fat and are very healthy. Because they’re slim (苗条的) they don’t have the leg problems like other dogs the same height. But they do feel the cold, especially since they would much rather be at home in bed than walking around outside.    

The text is written mainly______.

A. to tell people how to raise greyhounds

B. to let people know more about greyhounds

C. to explain why greyhounds are aggressive

D. to describe greyhounds of different colors

It can be inferred that greyhounds_______.

A. love big doghouses

B. like staying in bed all day

C. make the best guard dogs

Why does the author say that greyhounds make great pets?

A. They are big in size.

B. They live a very long life.

C. They can run races for some time.

D. They are quiet and easy to look after.

If you keep a pet greyhound, it is important________.

"Reduce, reuse and recycle, this familiar environmentalist slogan tells us how to reduce the amount of rubbish that ends up in landfills and waterways.

The concept is being used to deal with one possibly dangerous form of waste – electronic junk (电子垃圾), such as old computers, cell-phones, and televisions. But this process for managing e-waste may be used in an unscrupulous way more often than not used, a recent report suggests.

“A lot of these materials are being sent to developing nations under the excuse of reuse – to bridge the digital divide,” said Richard Gutierrez, a policy researcher.

One of the problems is that no one proves whether these old machines work before they hit the seaways. Because of this, the report says, e-waste is a growing problem in Lagos, Nigeria, and elsewhere in the developing world. Much of the waste ends up being thrown away along rivers and roads. Often it’s picked apart by poor people, who may face dangerous exposure to poisonous chemicals in the equipment.

Businessmen also pay workers a little money to get back materials such as gold and copper. This low-tech recovery process could expose workers and the local environment to many dangerous materials used to build electronics. According to Gutierrez, this shadow economy exists because the excuse of recycling and reusing electronics gives businessmen “a green passport” to ship waste around the globe. “Developing nations must take upon some of the responsibility themselves,” Gutierrez said. But, he added, “A greater portion of this responsibility should fall on the exporting state.”

China, for example, has become a dumping place for large amounts of e-waste. The nation is beginning to take action to stop the flow of dangerous materials across its borders. The Chinese government, after many years of denial, is finally beginning to take the lead.

The underlined word “unscrupulous” in Paragraph 1 probably means ________.

       A. unsafe               B. tricky                C. wrong                      D. immoral

What does the fourth paragraph mainly discuss?

       A. Old computers and TVs still work before they are sent abroad.

       B. Poor people break up e-waste to collect some valuable materials.

       C. A lot of e-waste is dumped in developing countries.

       D. The problem of e-waste is growing in developing countries.

From what Gutierrez said we can learn that ________.

       A. exporting countries should mainly be responsible for this problem.

       B. neither rich nor poor countries should be blamed for this problem

       C. developing countries should be responsible for this problem

       D. poor countries should blamed for this problem

It can be inferred from the last paragraph that _______.

       A. China has hidden a large amount of e-waste in many secret places

       B. China has greatly changed hre idea about the problem of e-waste

       C. China has prevented poisonous materials from entering China for a long time

       D. China is falling behind other countries in dealing with e-wast

The passage mainly tells us that _______.

       A. developing countries are facing serious environmental problems

       B. e-waste is a growing problem in developed countries

       C. e-waste is sent to developing countries under the excuse of reuse

       D. developing countries are making full use of e-waste

The African elephant, the largest land animal remaining on earth, is of great importance to African eco-system. Unlike other animals, the African elephant is to a great degree the builder of its environment. As a big plant-eater, it largely shapes the forest-and-savanna(大草原)surroundings in which it lives, therefore setting the terms of existence for millions of other animals and live in its habitat.

It is the elephant’s great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and under-bushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas. In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.

Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed(有蹄的)plant-eaters to move around and for small plant-eaters to get their food as well.

What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole eco-system.

66. What’s the passage mainly about?

A. Disappearance of African elephants.

B. Forests and savannas as habitats for African elephants.

C. The effect of African elephants’ search for food.

D. The eating habit of African elephants.

67. What does the underlined phrase “setting the terms” in the first paragraph most probably mean?

A. fixing the time.            B. worsening the situation.

C. Improving the quality.      D. Deciding the conditions.

68. What do we know about the open spaces in the passage?

A. They result from the destruction of rain forests.

B. They provide food mainly for African elephants.

C. They are home to many endangered animals.

D. They are attractive to plant-eating animals of different kinds.

69. According to the passage, which of the following statements is TRUE?

A. The African elephant has become extinct.

B. African elephants have 300 pounds of plants every day, including small trees and under-bushes.

C. The African elephant is in a way the builder of the environment like other land animals.

D. If the African elephant disappears, the whole eco-system won’t be affected.

70. The passage is developed mainly by _________.

A. presenting figures                       

 B. pointing out similarities and differences

C. describing the changes in the order of space      

 D. giving examples

Imagine being the only person in the Forbidden City. You could stay there all day without swarms of people crowding around. You'd be able to look at the ancient treasures without worrying about other visitors pushing you for a better view. Well, in two years time you'll be able to have such an experience, just like the former emperors used to. The only difference is that your Forbidden City fun will be online.

Thanks to new technology, a virtual tour of the Forbidden City will be available online by 2008. The project - jointly driven by the Palace Museum and computer company IBM - aims to help teenagers around the world become more interested in Chinese culture. The project will offer an interactive, three-dimensional view of the palace. The virtual tour will provide images from all over the 780,000-square-metre palace.

"The Palace Museum is a big book; there are always places you haven't read about," said Hu Chui from the museum. There are many rooms closed for protection. But the virtual platform breaks the boundaries of time and space, meaning visitors can see whatever they want. "The interaction and games content in the virtual tour will attract more young people to understand and love our cultural heritage," added Hu.

In the virtual tour, historical figures will actually talk to visitors and answer their questions. The stories behind the buildings and treasures will also be told. "The online environment, presented in both Chinese and English, enables visitors to experience the culture and stories of the museum," said James Yeh, an IBM official.
