One day, Mr. Arnold was teaching a lesson, and things were going as normally as ever. He was explaining the story of mankind to his pupils. He told them that, in the beginning, men were nomads; they never stayed in the same place for very long. Instead, they would travel about, here and there, in search of food, wherever it was to be found. And when the food ran out, they would move off somewhere else.

He taught them about the invention of farming and keeping animals. This was an important discovery, because by learning to cultivate(耕作)the land, and care for animals, mankind would always have food steadily available. It also meant that people could remain living in one place, and this made it easier to set about tasks that would take a long while to complete, like building towns, cities, and all that were in them. All the children were listening attracted by this story, until Lucy jumped up:

“And if that was so important and improved everything so much, why are we nomads all over again, Mr. Arnold?”

Mr. Arnold didn’t know what to say. Lucy was a very intelligent girl. He knew that she lived with her parents in a house, so she must know that her family were not nomads; so what did she mean?

“We have all become nomads again,” continued Lucy, “The other day, outside the city, they were cutting the forest down. A while ago a fisherman told me how they fish. It’s the same with everyone: when there’s no more forest left the foresters go elsewhere, and when the fish run out the fishermen move on. That’s what the nomads did, isn’t it ?

The teacher nodded, thoughtfully. Really, Lucy was right Mankind had turned into nomads. Instead of looking after the land in a way that we could be sure it would keep supplying our needs, we kept developing it until the land was bare. And then off we would go to the next place! The class spent the rest of the afternoon talking about what they could do to show how to be more civilized.

The next day everyone attended class wearing a green T-shirt, with a message that said “I am not a nomad!

And , from then on, they set about showing that indeed they were not. Every time they knew they needed something, they made sure that they would get it using care and control. If they needed wood or paper, they would make sure that they got the recycled kind. They ordered their fish from fish farms, making sure that the fish they received were not too young and too small. They only used animals that were well cared for, and brought up on farms.

And so, from their little town, those children managed to give up being nomads again, just as prehistoric men had done, so many thousands of years ago.

1.From Paragraph 2, we can know that______ .

A.people got tired of living in the same place

B.people gradually got used to living in cities

C.people tended to settle down after learning farming

D.people spent a long time in learning to keep animals

2.In the teacher’s opinion, Lucy’s argument was______

A.shocking          B.ridiculous         C.puzzling           D.reasonable

3.Which of the following agrees with the message “I am not a nomad” (Paragraph 7)?

A.People eat young fish for its delicious taste.

B.Foresters leave the place where wood is not available.

C.Fishermen move elsewhere when there is no fish left.

D.People use recycled materials as much as possible.

4.The writer tries to make us believe that ______.

A.mankind has been progressing mainly through traveling about

B.it’s unwise for mankind to use the land in an uncontrolled way

C.it’s quite good for students to learn more about the history of mankind

D.in the beginning men were nomads.

By day he is just a normal cat but when the lights go out, he glows (发光) in the dark.

Scientists have genetically modified (更改) a cat as part of an experiment that could lead to treatments for diseases.

   Named Mr. Green Genes, he looks like a six-month-old cat but, under ultraviolet (紫外线的) light, his eyes, gums (牙龈) and tongue glow green. That is the result of a genetic experiment at the Audubon Center for Research of Endangered Species in New Orleans, US.

   Mr. Green Genes is the first fluorescent (荧光的) cat in the US and probably the world, said Betsy Dresser, the center's director.

   The researchers made him so they could learn whether a gene could be introduced harmlessly into a cat's genetic sequence (次序).

   If so, it would be the first step in a process that could lead to the development of ways to treat diseases via gene therapy (治疗).

   The gene, which was added to Mr. Green Genes' DNA, has no effect on his health, Ms Dresser said.

   Cats are ideal for this project because their genetic makeup is similar to that of humans, said Dr Martha Gomez, a scientist at the center.

   To show that the gene went where it was supposed to go, the researchers settled on one that would glow.

   The gene "is just a marker", said Leslie Lyons, an assistant professor at the University of California, Davis. Lyons is familiar with the center's work.

   "The glowing part is the fun part," she said.

   Glowing creatures made international news earlier this month when the Nobel Prize in Chemistry was awarded to three scientists who had discovered the gene through their work with jellyfish (水母).

51. Which of the following might be the best title for the passage?

A. A Glowing Cat         B. Mr. Green Genes

C. One Cat’s Life         D. An experiment on cats

52. What can we conclude from the passage?

A. Fortunately, scientists have found ways to treat diseases via gene therapy.

B. Scientists think cats’ genetic makeup is the same as that of human beings.

C. Three scientists who had discovered the gene were given Nobel Prize in  Physics.

D. Scientists have managed to introduce a gene into a cat’s genetic sequence.               

53. What does “settled on”  most probably mean in Paragraph 9?

A. chose       B. killed     C. took        D. raised

54. From the passage we can see that ____.

A. Mr. Green Genes was made by researchers to treat diseases

B. the cat named Mr. Green Genes can glow when it is dark

C. Mr. Green Genes is the first fluorescent cat in the world

D. Mr. Green Genes is a cat of seven months old up to now

55. Which of the following is WRONG according to the text?

A. The gene added to Mr. Green Genes’ DNA doesn’t affect its health at all.

B. The scientists came up with the idea of the glowing genes totally for fun.

C. Earlier this month glowing creatures became news all through the world.

D. Scientists had discovered the gene from the jellyfish they worked with.
