1、现代大学英语听力2听力原文及题目答案Unit y, too. They are active, but not as active as the thinner mice. But they only live about two years, not the three years or more of the thinner mice. The last group of mice is receiving more food than the other two groups. Most of the day, these mice are eating or sleeping. The
2、yre not very active. These mice are living longer than the scientists thought about a year and a half. But they are not healthy. Theyre sick more often than the other two groups. The experiment is still going on. The scientists hope to finish their studies in two years. Task 2 A. 1) People keep fish
3、 in a certain place just as they keep sheep and cattle. 2) By education. 3) Waste pollutes the sea, and plankton dies. Other sea animals that live on plankton cannot find enough food. 4) They needed to kill whales for their meat, their bones and the oil from their fat. But they have other materials
4、now. B. Scientists Ideas Start more fish farms on land Stop fishing in certain parts of the Ocean Only allow each country to catch a certain number of fish Stop killing whales C. People on land Large fish Smaller fish Zoo plankton Plant plankton Mike: Good morning, and welcome to Radio Time. For our
5、 monthly programme, Science Today, Ive invited a group of scientists to the studio to talk about sea life Professor Adams, Dr. Brown and Dr. Church. Its good to have you with us. Professor Adams, Ive read in the papers that sea life is in danger. Is this true? Adams: Im afraid so, very true. As the
6、world population grows, we need more food, so we catch more fish. Were overfishing the sea, and soon there wont BE any fish. Brown: The answer is to start more fish farms on land. Church: I agree. We must keep fish, like we keep sheep and cattle. Adams: Fish farms are a good idea, but I dont think t
7、hey will solve the problem of overfishing the sea. We have to stop people fishing in certain parts of the ocean. Church: Yes. We need international rules to protect fish, and all the countries of the world must agree to obey them. Brown: We have rules now, and people dont obey them. I agree that we
8、must stop fishing in Adams Brown Church certain parts of the ocean. Adams: And we must only allow each country to catch a certain number of fish but how do we make people obey these rules? Church: I dont know. By education perhaps? Mike: You mean, teach people about sea life? Church: Exactly. We mus
9、t explain how everything depends on everything else. If people want to eat fish in the future, then they must stop killing so many fish now. Brown: Waste is another problem. Were filling the oceans of the world with our rubbish. The sea can no longer clean itself. Its not safe to swim near the beach
10、es, and out at sea plankton is starting to die. Adams: And without plant plankton for the zoo plankton, and zoo plankton for small fish and shellfish, the large fish cant find any food, and so it goes on. Church: One reason why whales are disappearing is that they cant find enough food. Mike: Whales
11、 eat plankton, dont they? Church: Yes. And some people still want to eat whale meat. In the past people needed to kill whales for their meat, their bones and the oil from their fat. But we have other materials now. People must stop killing whales. Brown: I agree. We mustnt lose the largest sea mamma
12、l in the world. Adams: Everyone must work to save the whale. Its a wonderful animal, and it has a right to life. Mike; And everyone must try to understand about sea life and protect it. Well, thank you for coming on the program me and I hope our listeners will remember what you said. Dont let our oc
13、eans die, and remember, no food for the fish means no fish for food! Task 3 A. 1) b 2) a 3) b 4) c B. 1) Measure; Mix; Pour; Put on; Pack 2) late; sick; vacations; strike; 24 hours; 7 days; 365 days C. 1) A worker will program the robots. She/He will type the orders into a computer, telling the robo
14、ts what ingredients to use, how long to mix them, and which labels to use. 2) A technician from the robot company will come within an hour to fix it. 3) No. Boss: Robots? Why are you talking about robots? Were a small company, we make cough syrup. We only have twenty workers. Robots are fine for lar
15、ge factories, not small ones like ours. Assistant: Boss, small companies can use robots, too. Theyre great workers. Boss: I dont know. Talk to me about them ten years from now. Assistant: Boss, listen, this is a simple operation here. We make 10 different kinds of cough syrup. But each operation onl
16、y has 5 steps, so well only need 5 robots. One robot will measure the ingredients, and a second robot will mix them. A third robot will pour the syrup into the bottles. Then a fourth robot will put the labels on. The last robot will pack the bottles into boxes. Right now, we have 20 workers doing th
17、ese jobs. Boss: But each kind of syrup is different. How will these robots know what to do? Assistant: Well tell them. One worker will program the robots. Shell just type the orders into a computer, tell the robots what ingredients to use, how long to mix them, and which labels to use. Boss: And wha
18、t happens when one of the robots breaks down? Assistant: They dont break down very often. And the robot company will have a technician here within an hour. Boss: I just cant picture it. What will we have here? A quiet building with robots rolling around doing the work? Assistant: Thats it! And these
19、 robots are great workers. Theyll never come to work late, they wont call in sick, they wont take vacations, they wont go on strike, and theyll work 24 hours a day, 7 days a week, 365 days a year. Boss: I dont know. It sounds like a good idea, but I need time to think. What about the men and women w
20、ho work here now? Most of them are good workers. They have families to support. Assistant: Boss, thats the only problem. We wont need them anymore. Task 4 A. inventions; immediate; manufactured goods; growth; farms; grew up; coal; iron; pleasant; over-crowded B. Part 2 Factory A. 1. Long 2. Low B. c
21、ommon C. children Part 3 women and children A. 10 years old; mines B. 10 working hours/day for women and for boys under 18 C. form unions C. 1) Socialists demanded complete changes in the system of Government and the way people earned their living. But other social reformers only wanted to achieve t
22、heir goals by peaceful means, particularly by passing new laws. 2) The Consequences of the Industrial Revolution in Britain Part 1 The early inventions and discoveries which began the Industrial Revolution had important consequences. One immediate result was the great increase in the quantity of man
23、ufactured goods available. Another important result was the rapid growth of cities. Many country people left their farms to work in factories. Gradually, new towns grew up around these factories which were built near the sources of coal, iron and waterpower. Some of the great cities of England, such
24、 as Manchester, Leeds and Birmingham, started in this way. The industrial towns were not pleasant places to live in. The workers quarters were over-crowded and the people lived in the midst of filth and disease. Part 2 The Industrial Revolution also brought about what was later called the factory sy
25、stem. Working conditions in factories were bad. The people had to work long hours for small wages. Accidents were common and the employer took no responsibility for them. The most unfortunate victims of the factory system were children. Children only four or five years old were employed in factories
26、 and mines. Part 3 Many influential people began to protest against the terrible conditions under which the people lived and worked. Gradually, the English Parliament made new laws to protect workers, particularly women and children. In 1842, it was made illegal to employ women, and children under t
27、en years old, to work in the mines. Another law was passed in 1847 allowing only ten hours of work per day for women and for boys under eighteen years of age. After 1824, working men were also allowed to form unions to bargain peacefully with their employers for better working conditions and better
28、wages. Strikes were, however, forbidden for many years. Part 4 As the factory system grew, a number of men criticized its evils. Some of these men merely wanted new laws to protect the workers. Others, who were later known as Socialists or Communists, demanded complete changes in the system of Gover
29、nment and the way people earned their living. Task 5 A. 1) T 2) T 3) F 4) T 5) F 6) F 7) T 8) T Miranda went to one side of the control room and touched a button. The door of the safety room slid open. Miranda went inside and closed the door. She had a plan of her own. The large blue capsules were o
30、n the tray which had come out of the wall. Miranda picked up a capsule and opened it carefully. It was full of white powder. She emptied the white powder into some water. Then she poured the liquid into an injection gun. Miranda put the gun carefully into a pocket in her overalls. She now had a weap
31、on of her own. Garth will not think of searching me, Miranda said to herself. He doesnt know I have a different plan for the crystals. Miranda went back to the control room. Omega was silently charging the power banks. The visual display showed the sleeping bodies of Garth and Varon. When will the s
32、hip be ready to leave for Zeron? she asked Omega eagerly. In three and a half hours time, was Omegas reply. Keep watching Garth, Miranda ordered. But you can stop watching Varon. He is locked in his cabin. He cannot get out until I open the door. It will be done, Omega answered. He pressed the butto
33、n on the control panel. The picture of Varon disappeared and the picture of the sleeping body of Garth filled the screen. Miranda went out into the corridor and walked the short distance to Varons cabin. She touched a button in the wall and the door opened immediately. Varon was lying asleep on the
34、bunk. Miranda looked down at him. Youre a fool, she thought. How can you lie there sleeping? Anyone who trusts Garth is a fool. She shook Varon by the shoulder until he woke up. Whats wrong? he asked sleepily. Are we ready to leave? Not yet, replied Miranda. I have come to talk to you. I want you to
35、 help me. I am going to help you to get the Zeron crystals. What more help do you want? asked Varon. You know very little about me and Garth, began Miranda. I know enough, interrupted Varon. You are thieves. And you are murderers! I am not a murderer, said Miranda. I helped Garth on Earth. But I did
36、 not kill the owner of this spaceship. Task 6 A. 1) c 2) b 3) c B. Speakers Professor Ports Does she/he believe there is the monster Why or why not? in Loch Ness? No. If there are any monsters there, why hasnt any-one caught one yet? Why arent there any really clear photos of one? Macadam Dr. Hunt Y
37、es. He says he has seen it. He didnt believe in He believes there may be something unusual in Loch the idea, but now he Ness. is not so sure. He says, The underwater world is still full of mysteries. Potts: Now, Mr. Macadam, what makes you so sure that there is a monster in Loch Ness? Macadam: Ive s
38、een it, Professor Potts! Ive seen it with my own eyes, I tell you! I was there by Loch Ness very early one morning. I was standing by the edge of the lake. Suddenly I saw a pair of eyes in the water. They were looking at me. Then a head came up out of the water, and this thing began to swim towards
39、me. I was really frightened, you know! I was holding a bottle in my hand at the time. I threw it at the monster. Then the monster dived and swam away underwater. But I know you dont believe my story, do you, Professor Potts? Potts: Well, I believe that you saw something. But are you certain that it
40、was a monster? Could you see it clearly? Are you sure that it wasnt just some kind of animal or bird? You see, I dont believe in monsters. And I dont think theres anything strange or unusual in Loch Ness. If there are any monsters there, why hasnt anyone caught one yet? Why arent there any really cl
41、ear photos or films of one? Macadam: Ah, well let me explain. Loch Ness is very deep, you know more than 200 metres deep in some places. And the waters a dark brown colour. These monsters dont come to the surface of the lake very often. They live in deep water, near the bottom of the lake. You cant
42、see much down there. So its very hard to find these monsters. And its harder to catch one. Dr. Hunt knows a lot about Loch Ness. You believe theres a monster there, dont you, Doctor? Dr. Hunt: Well, actually, I used to think that the whole idea of Nessie was just a joke. But now Im not so sure. Nowa
43、days we know a lot about land animals, but the underwater world is still full of mysteries. I dont like the word monster, but I believe there may be something unusual in Loch Ness. It may be a big animal. It may be a fish that scientists dont know about. It could even be a kind of dinosaur that didn
44、t die 65 million years ago. Who knows? Its an exciting idea, but we cant be certain until we have some better pictures, or, best of all, until someone catches one of these things so that scientists can study it properly. Task 7 A. 1) F 2) T 3) F 4) F 5) T B. 1) Dispute over the genetically modified
45、crops. 2) Biotech foods come from material that has been genetically modified by scientists to resist in-sects or disease. 3) European consumers feared possible health risks of these new foods. 4) First the foods must be labeled clearly. Second, producers will have to trace GMOs at all stages of pro
46、duction. 5) Because the aid contained biotech grain, which Africans feared could be used as seed and thereby threaten future exports to the EU. The European Parliament on Wednesday passed two laws that could open the way for European Union nations to lift an unofficial ban on genetically modified cr
47、ops. This is a major trade issue with the United States, whose farmers claim the ban has cost almost $300 million a year in lost corn exports. The new laws, expected to be adopted by EU governments before the end of the year, would allow the distribution of genetically modified foods as long as they are clearly labeled. The rules would also force producers to trace genetically modified organisms, or GMOs, at all stages of production. The new laws require the 15 nations of the EU to establish their own measures to prevent seeds from farms growing genet
