题目列表(包括答案和解析)


After spending years searching for a planet with life, scientists may have found one. In September 2010, a team of US scientists discovered an Earth-sized planet called Gliese 581g. It has a surface temperature neither too hot nor too cold for liquid(液态)water. Scientists think there is a chance that the planet could have life.
The planet Gliese 581g goes around a star called Gliese 581, which is about 20 light-years from Earth. That is about 194 trillion(万亿)kilometres -500 million times farther away from us than the moon.
A spacecraft traveling at a one-tenth of the speed of light would reach Gliese 581g within about 220 years. A human can’t live that long, but robotic explorers could make the job easier. However, our fastest spacecraft don’t come anywhere near that one-tenth light-speed mark.
At present, scientists don’t know what the surface might be like on Gliese 581g. What they know is that the planet is at the sight distance from its star to have liquid water. It’s also at the right distance to have an atmosphere that could protect the water if it is on the surface.
Although spacecraft won’t be getting there anytime soon, one way to look for life on Gliese 581g is to turn our radio telescopes(望远镜)towards the planet and search for radiation(放射). By studying the radiation, scientists would find out about the chemicals(化学物质)around the planet and discover it Gliese 581g has an atmosphere. If it has one, studying the atmosphere would give us a good idea if the planet has life or not. But it’ll probably be many years before we can do this properly.
People have been arguing about whether there is alien life on Gliese 581g. Any discussion about alien life is just guessing at this point, according to its discoverers.
【小题1】 What did scientists find in September 2010?
A.A planet with water. B.A planet similar to the earth.
C.A planet without life.D.A planet near the earth.
【小题2】According to the article, Gliese 581g ________.
A.is at the right distance from its starB.moves around the earth
C.is as far away from us as the moonD.can be reached in about 220 years
【小题3】 Paragraph 5 is mainly about ______.
A.the possibility of living on Gliese 581g
B.the kinds of chemicals around Gliese 581g
C.the way of looking for life on Gliese 581g
D.the aim of studying the radiation on Gliese 581g
【小题4】Which of the following is the best title for the passage above?
A.Gliese 581g, a Likely Living PlanetB.Gliese 581, a Likely Living Planet
C.Gliese 581g and Its StarD.Gliese 581g and Radiation

 (One day Alice runs after a strange rabbit and comes into a deep hole. She becomes smaller when she wakes up the next day. She finds herself in a wonderland with many amazing things inside.)   

The Caterpillar(毛毛虫) and Alice looked at each other for some time in silence. At last the Caterpillar took the pipe out of its mouth, and said to her in a tired, sleepy voice.   

“Who are YOU?” said the Caterpillar.

This opening for a talk couldn’t make Alice at ease. Alice replied, rather shyly, “I----I hardly know, sir, just at present ----at least I know who I was when I got up this morning, but I think I must have been changed several times since then.”

“What do you mean by that?” said the Caterpillar, “Explain yourself!”

“I can’t explain MYSELF. I’m afraid, sir.” said Alice, “because I’m not myself, you see.”

“I don’t see.” said the Caterpillar.

“I’m afraid I can’t put it more clearly.” Alice replied very politely, “for I can’t understand it myself. And being so many different sizes in a day is very puzzling.”

“It isn’t.” said the Caterpillar.

“Well, perhaps you haven’t found it so yet.” said Alice. “But when you have to turn into a chrysalis(蛹,茧)----you will some day, you know ----and then after that into a butterfly, I think you’ll feel it a little stranger, won’t you?”

“Not a bit.” said the Caterpillar.

“Well, perhaps your feelings may be different.” said Alice. “All I know is, it would make ME feel very strange.”

“You!” said the Caterpillar scornfully(鄙视地). “Who are YOU?” The question brought them back again to the beginning of the talk. Alice felt a little angry because the Caterpillar was making such VERY short sentences. She drew herself up and said very seriously, “I think you ought to tell me who YOU are first.”

“Why?” said the Caterpillar.

Here was another puzzling question. As Alice could not think out any good reason, and as the Caterpillar seemed to be very unpleasant, she turned away.

“Come back!” the Caterpillar called after her. “I’ve something important to tell you!”

This certainly gave Alice some hope. Alice turned and came back again.

1.Where may their talk take place?

A. In a wonderland. B. In the field.           C. In the tree.   D. Outside the hole.

2.Why did Alice think she was not herself?

A. Because she was too young to understand the changes.

B. Because being changed several times in a day made her feel puzzled.

C. Because she didn’t like her changes

D. Because she didn’t feel very well.

3.Which of the following sentences can be added to the end of the story?

A. “Don’t be silly. You are still yourself.” said the Caterpillar.

B. “Don’t be angry. You think you’re changed, do you?” said the Caterpillar.

C. “Don’t be sad. You’ll grow bigger again.” said the Caterpillar.

D. “Don’t be afraid. You can go home now.” said the Caterpillar.
