Should we try to contact and make friend...

Should we try to contact and make friends with other beings in the universe? Certainly not,says British physicist Stephen Hawking.

“If aliens(creatures from other planets)ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn’t turn out very well for the Native Americans,’’ said the 68-year-old disabled scientist in a new Discovery documentary (纪实性电视节目) on April 25.

The program pictures an imagined universe where other life forms in huge spaceships hunt for resources after using up all those on their home planets.

“Such advanced aliens would perhaps become nomads(游牧民),looking to conquer and colonize whatever planets they can reach,”warned Hawking.

On the probability of other life forms existing, he says, “To my mathematical brain, the numbers alone make thinking about aliens perfectly reasonable.”

Hawking’s concerns have frightened some people and been met with disagreement from other researchers.Paul Davies, author of the book Renewing Our Search for Alien Intelligence,thinks Hawking’s reasoning is wrong.

He argues that since Earth is about 4.5 billion years old,if intel1igent life is likely , communities of other beings may have been there for a very long time.

“If resources are the factor, then at least one group of aliens would surely have visited Earth as a destination mil1ions of years ago.

Even if other life forms do come to Earth in the near future, Davies believes comparisons with are wide of the mark(离谱的).

68. What is the article mainly about? 

A. Other life forms coming to our planet.

B. Scientific evidence of other life forms.

C. Earth as the only place where human beings can survive.

D. Hawking’s belief that other life forms may exist in the universe.

69. Which of the following ideas is opposed to Hawking’s view?

A. Other life forms exist in the universe.

B. 0ther life forms may be more intelligent than human beings.

C. We should try to contact other 1ife forms from other planets.

D. Other life forms may exist in more than one part of the universe.

70. Paul Davies didn’t agree with Stephen Hawking ,believing that ________.

A. the universe is running out of resources

B. humans are the best creatures in the universe.

C. it is a good idea to avoid meeting with other life forms   

D. Davies doesn’t think it proper to compare aliens with Columbus

A low-carbon lifestyle means cutting carbon dioxide emissions and living a life characterized by low-energy use, low consumption and low spending. This way of living is being accepted by a growing number of average people in China.

Before low-carbon became a popular word here, some environmentally conscious people known as "Lohas" had already devoted themselves to living green, low-carbon lifestyles. Lohas is for "lifestyles of health and sustainability." It was first introduced in 1998 by American sociologist Paul Ray and later became a popular lifestyle in western countries. After this concept was introduced into China a few years ago, Lohas was translated into a proper Chinese word "lehuo," meaning happy living.

Zhang Tao from a joint venture in Beijing is a Lohas supporter and follower. He and some others set up a Lohas club two years ago. They often get together to share their experiences about living green lifestyles or to volunteer for environmental protection activities.

Zhang says Lohas is both a lifestyle and an attitude towards life rather than just a fashion or slogan.

"A Lohas lifestyle means a natural and healthy life with low costs. We don't drive cars, and we try our best to save water and electricity. Some people misunderstand us as being too stingy. But in fact, most of us are well-paid. We don't do it to save money, but for the sake of the environment. Living a rich life doesn't mean you can waste resources. We hope what we do can help save energy and reduce the pressures on earth. I know our personal strength is too small, but the changes will be great if everyone can make a little contribution."

64. A low-carbon lifestyle has the following features except_______.

A. low energy     B. low wages     C. low consumption   D. low spending

65. A Lohas is most likely to_______.

A. drive a car to work every day   B. save money to live a better life

C. turn off the tap when not using   D. leave the light on day and night

66. What does the word “stingy” mean in the last paragraph?

A. generous               B. mean              C. rich                D. willing

67. In Zhangtao’s opinion, _________.

A. Lohas is just a fashion or form     B. one shouldn’t get well paid

C. one should live a happy life             D. environment protection depends on everyone

第三部分阅读理解(共20小题;每小题2分,满分40分)

阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

Spiders are actually useful. They do not harm plants, as some people think. Instead, they protect plants by controlling insects. If you see spiders in a garden, it doesn’t mean the garden is unhealthy. It means the spiders are helping the garden stay healthy.

If you spend some time watching spiders, you may be surprised by what you see. There are many wonderful webs. They may perform skillfully on their thin silk threads. However, some spiders spin (织) no webs at all. They follow insects on the ground with all the skill and cruelty of a tiger hunting big game.

Scientists have named about 30,000 species of spiders, but they think this is only one-fourth of all the different kinds of spiders in the world. In most species, people can easily tell the female spider from the male because the female is much bigger. For example, the female black widow (黑寡妇) weighs about one hundred times as much as the male.

Female spiders lay eggs. After hatching (孵), most spiders live less than a full year, but some don’t. Tarantulas (狼蛛) do not become adults until they are 10 or 11 years old. Female tarantulas often live an extra 10 years! The baby spiders that hatch from the eggs are called spiderlings.

56. The underlined in Paragraph 2 part “a tiger hunting big game” refers to “______.”

A. laying eggs                  B. hatching baby spiders

C. spinning webs               D. catching insects

57. How many kinds of spiders are there in the world according to the passage?

A. About 30, 000.      B. About 60, 000.    C. About 90, 000.    D. About 120, 000.

58. What can we know from the passage?

A. If there are spiders in your garden, it means it is unhealthy.

B. All spiders can spin webs.

C. Normally, a male spider is smaller than a female one.

D. All spiders can live 10 or 11 years after hatching.

59. What will be probably talked about after the last paragraph?

A. The way spiders spin webs.                   B. Something about spiderlings.

C. How the spiders protect plants.                 D. The way spiders stay healthy.
