[00:18.64]Model Test 3

[00:20.91]Part III Listening Comprehension

[00:24.79]Section A

[00:26.58]Directions: In this section,

[00:29.99]you will hear 8 short conversations and 2 long conversations.

[00:35.61]At the end of each conversation,

[00:37.90]one or more questions will be asked about what was said.

[00:42.19]Both the conversation and the questions will be spoken only once. [00:47.88]After each question there will be a pause.

[00:51.47]During the pause,

[00:52.85]you must read the four choices marked A), B), C) and D),

[00:58.73]and decide which is the best answer.

[01:02.00]Then mark the corresponding letter on Answer Sheet 2

[01:06.30]with a single line through the centre.

[01:09.09]Now let's begin with the 8 short conversations.

[01:14.58]11. W: Have you finished reading my research report?

[01:20.07]I put it on your desk last week.

[01:23.44]M: Yes, but you have to revise some parts of it, I'm afraid,

[01:28.77]if you want to get it published.

[01:32.29]Q: What does the man suggest the woman do?

[01:50.31]12. M: I'm afraid I'm a day or two late with my registration fees. [01:57.67]My paycheck didn't come on time this month.

[02:01.93]W: It's all right. We're allowing a grace period until Friday.

[02:07.32]Q: What does the woman mean?

[02:24.18]13. M: Mike got an A in Economics and only a C in Political Science. [02:33.99]W: But he still thinks that Political Science is less complicated than Economics.

[02:40.54]Q: What do we learn from the conversation?

[02:58.14]14. M: I just stopped by your office in the bank. They told me that you had quit.

[03:07.30]Where are you working now?

[03:10.35]W: I am working for a lawyer now.

[03:12.64]The pay is better and the work is much more interesting.

[03:17.44]Q: What do we learn from the conversation?

[03:35.21]15. W: They say you were quite successful in correcting the plan ahead of schedule.

[03:43.55]M: Well, I would be on my way doing the job

[03:47.11]if it had not been for your help last year.

[03:51.73]Q: What does the man mean?

[04:08.69]16. W: I expected to see you at Sam's birthday party yesterday but you were absent.

[04:17.61]M: I had a date with my girlfriend. I have been terribly busy these days. [04:23.89]You know, she is complaining.

[04:27.72]Q: What do we learn from the conversation?

[04:45.49]17. W: About that money I lent you, isn't today the day you said you'd return it?

[04:54.78]M: Oh, my finances have been really tight this month,

[04:59.25]but all I need is a few more days.

[05:03.22]Q: What does the man imply?

[05:20.43]18. W: I have tried my best to win a prize since I joined the music team, [05:27.81]but three years later I still haven't.

[05:31.47]M: It takes so much time from your homework.

[05:34.83]Perhaps you should forget about music for now.

[05:39.20]Q: What does the man suggest the woman do?

[05:57.30]Now you'll hear the two long conversations.

[06:01.83]Conversation One

[06:04.73]W: Hi, Jack. How was the camping last week?

[06:08.66]M: Oh, it was horrible. We nearly got killed.

[06:13.43]W: What happened?

[06:15.49]M: Well, when we were walking on the path along one of the hills [06:21.32]a bear suddenly jumped out of a bush and started to chase us.

[06:27.39]W: That's terrible. Did anybody get hurt?

[06:31.94]M: Fortunately, we ran away before the bear got closer.

[06:37.02]We all agreed that we had never run so fast in our whole lives.

[06:44.19]W: So why did the bear try to attack you? Was it hungry and looking for food?

[06:51.11]M: No, it was more horrible. We later found out that the bear was a mother. [06:58.49]And she was separated by us from her baby.

[07:02.79]She jumped out because she feared that her kid would get hurt.

[07:07.75]After the camping we learned not to get between an adult and any young bears. [07:15.96]W: But how could you make sure that you can see the bears?

[07:19.71]Supposed the mother and the children are hidden in a bush?

[07:24.07]M: Well, it's actually easy to avoid encounter with bears.

[07:29.67]They are shy animals and normally avoid human beings.

[07:35.20]In most of the cases they attack because they are shocked

[07:40.22]by the unexpected presence of human.

[07:43.99]What you have to do is to scare them away

[07:47.74]by making noises before you get too close.

[07:52.03]W: I see, so next time when I go camping I'll sing aloud when I'm walking. [07:58.56]M: That's a good idea.

[08:02.84]Questions 19 to 22 are based on the conversation you have just heard. [08:10.61]19. What happened during the man's camping?

[08:28.72]20. Why did the mother bear jump out?

[08:46.54]21. Why do bears attack people?

[09:04.68]22. How to scare bears away before getting too close?

[09:24.29]Conversation Two

[09:27.56]W: Good morning. I'd just like to ask you a few questions about your visa application.

[09:34.43]Can you just check that the information here is correct?

[09:38.84]M: Sure. ... yes, that's all correct.

[09:43.18]W: Thank you. For your student visa,

[09:46.34]we need evidence of your financial status for the last five years. [09:51.72]In your application, you only included it for four years.

[09:56.95]M: Really? Let me check if I have the document here...

[10:01.63]Yes, here is the document you need. I'm sorry.

[10:06.78]I must have forgotten to make a copy of it for you.

[10:11.43]W: Thank you. That's fine. The documents relating to your education are fine.

[10:17.96]The offer from the university is conditional on your

[10:21.24]English language proficiency test result. Do you have that yet?

[10:27.06]M: Not yet. I took the test last weekend.

[10:30.77]The results will not be available for another two or three weeks. [10:37.85]W: OK. Everything else is in order.

[10:41.23]I'll be happy to give you a student visa, valid for the duration of your course,

[10:46.90]when you bring me a certificate showing the result of your language test. [10:51.76]M: Thank you very much.

[10:53.80]You don't need any other document from me to process my application? [11:00.72]W: None. Make an application to see me when you receive your results. [11:06.35]When you bring the certificate to me, bring your passport too.

[11:10.60]Then I can give you the visa.

[11:13.13]M: Thank you very much.

[11:15.30]W: Glad to help.

[11:19.02]Questions 23 to 25 are based on the conversation you have just heard. [11:26.23]23. What did the man forget to do?

[11:44.66]24. What do we learn about the man's English language proficiency test? [12:05.60]25. What should the man bring with him to get the visa?

[12:25.03]Section B

[12:26.73]Directions: In this section,

[12:29.76]you will hear 3 short passages.

[12:32.44]At the end of each passage,

[12:34.67]you will hear some questions.

[12:36.78]Both the passage and the questions

[12:39.11]will be spoken only once.

[12:41.66]After you hear a question,

[12:43.59]you must choose the best answer from the four choices

[12:46.89]marked A), B), C) and D).

[12:51.22]Then mark the corresponding letter on Answer Sheet 2

[12:54.81]with a single line through the centre.

[12:57.86]Passage One

[12:59.83]America's national symbol, the bald eagle, almost went extinct 20 years ago.

[13:06.78]But it has made a comeback.

[13:09.00]In fact, the US Fish and Wildlife Service is considering

[13:14.07]the possibility of taking it off the endangered-species list.

[13:19.07]Once, more than 50,000 pairs of bald eagles nested across the country. [13:25.12]But by 1960, that number had fallen below 400.

[13:31.63]The chief killer was the widely used DDT. Fish soaked up DDT, died, [13:39.31]and were washed up on shores, where bald eagles ate them up.

[13:44.25]DDT caused eagle eggshells to weaken and crack.

[13:49.47]The shells became so thin that they cracked before the babies emerged from the eggs.

[13:55.99]The eagle had no defense against DDT.

[14:00.51]Fortunately, in 1972, a law was passed to ban DDT,

[14:07.30]which saved the bald eagle from dying out.

[14:10.54]And since then, wildlife biologists have reintroduced bald eagles [14:15.86]from Canada to America. The result was that last year

[14:21.11]U.S. birdwatchers counted 11,610 bald eagles in the country.

[14:28.06]If it were dropped from the endangered list,

[14:30.89]the bald eagle would still be a threatened species.

[14:35.48]That means the bird would continue to get the same protection-

[14:39.37]no hunting allowed, and no disturbing of nests.

[14:43.62]But bald eagles still face tough times.

[14:47.67]The destruction of their natural homes could be the next DDT,

[14:52.43]causing eagle numbers to drop quickly.

[14:58.13]Questions 26 to 29 are based on the passage you have just heard.

[15:05.23]26. What do we learn about the bald eagle?

[15:24.24]27. How did DDT affect the bald eagles?

[15:43.88]28. What has been done to prevent bald eagles from dying out?

[16:04.35]29. According to the passage, what will cause the number of bald eagles to decline?

[16:27.23]Passage Two

[16:29.69]More and more Americans have been leaving their cars at home

[16:35.11]and riding to work on bicycles. They are doing this because of gas prices, [16:42.72]a slowing economy and concerns about the environment.

[16:48.75]Andy Clark is the executive director of the League of American Bicyclists. [16:55.98]His group supports bicycling for fun, fitness and transportation. [17:03.10]Clark says this is good news for the environment.

[17:07.22]He says riding a bicycle to work

[17:09.95]does not burn fossil fuel or create dangerous pollutants.

[17:15.58]Experts say the effects are the most important on short trips.

[17:21.28]Shorter car trips release more pollution into the air for each kilometer driven.

[17:28.36]This is because the device in a car engine that reduces the harmfulness of emissions

[17:36.43]needs to warm up before it can work well.

[17:40.79]Last year, the Pacific Northwest city of Portland, Oregon,

[17:46.33]had the highest percentage of bicycle commuters in the United States. [17:53.05]Portland has been doing progressive city planning for many years [17:58.55]to create special paths for bike riders.

[18:02.93]Andrew Land is one of Portland's citizens who bikes to work every day. [18:09.79]Mr. Land is 33 years old and has never owned a car.

[18:16.09]He has biked to work for 12 years.

[18:19.61]Before moving to Portland 6 years ago, he lived in Washington, D.C. [18:25.92]But he was hit by a car twice while biking to work there.

[18:31.22]That has not happened in Portland where there are special roads for bicycles.

[18:40.05]Questions 30 to 32 are based on the passage you have just heard.

[18:47.20]30. Why do more and more Americans choose to ride to work?

[19:06.70]31. What's the purpose of the progressive city planning in Portland? [19:26.21]32. What do we learn about Andrew Land from the passage?

[19:45.99]Passage Three

[19:48.68]Scientists have long thought about the idea

[19:51.86]of replacing a diseased organ with a healthy one from a donor.

[19:56.83]The problem at first was that the human body

[19:59.81]is not particularly receptive to foreign tissue.

[20:04.29]When tissue from a donor is placed inside the body,

[20:07.98]the immune army sees it as a foreign invader and goes into battle mode. [20:14.09]White blood cells attack and destroy the unknown tissue

[20:17.64]in a process known as rejection.

[20:21.10]Eventually, scientists realized that the problem of rejection didn't occur [20:26.65]when the organ donor and recipient were identical twins.

[20:31.72]The genetic similarity appeared to prevent the immune response.

[20:36.61]Massachusetts surgeon Joseph E. Murray used this concept to his advantage in 1954,

[20:44.27]when he accomplished the first successful kidney transplant between identical twins.

[20:51.38]Dr. Murray's surgery was a major breakthrough, but it wasn't a solution.

[20:56.84]After all, very few people have an identical twin they can rely on for organ donation.

[21:04.26]In the late 1960s, doctors figured out a way

[21:08.06]to perform transplants between non-relatives

[21:11.86]by suppressing the recipient's immune response with drugs.

[21:16.48]But the trouble was that the drugs were highly poisonous.

[21:20.37]Between the risks of infection and the poisonous drugs,

[21:23.96]most transplant patients didn't live long after their operation.

[21:29.83]By the 1980s, anti-rejection drugs had improved to the point

[21:34.69]where transplantation surgery became pretty routine and far less risky. [21:40.66]Survival rates rose.

[21:43.19]Once surgeons became experienced in transplanting essential organs [21:47.69]such as heart, kidneys, liver and lungs,

[21:51.35]they turned their focus to "nonessential" parts of the body.

[21:58.15]Questions 33 to 35 are based on the passage you have just heard.

[22:04.67]33. What was the problem of organ transplant at the beginning?

[22:24.87]34. In what condition would rejection not occur?

[22:44.06]35. What did surgeons do after they got familiar

[22:50.12]with the transplant of essential organs?

[23:06.79]Section C

[23:08.66]Directions: In this section,

[23:11.38]you will hear a passage three times.

[23:14.47]When the passage is read for the first time,

[23:17.16]you should listen carefully for its general idea.

[23:20.59]When the passage is read for the second time,

[23:23.26]you are required to fill in the blanks numbered

[23:25.70]from 36 to 43 with the exact words you have just heard.

[23:31.34]For blanks numbered from 44 to 46

[23:34.64]you are required to fill in the missing information.

[23:38.26]For these blanks,

[23:39.47]you can either use the exact words you have just heard

[23:42.63]or write down the main points in your own words.

[23:46.08]Finally, when the passage is read for the third time,

[23:49.27]you should check what you have written.

[23:51.88]Now listen to the passage.

[23:55.12]It's well known that big animals, like polar bears,

[23:59.71]are sensitive to climate change.

[24:03.27]The Earth warms, polar ice melts, and the bears are out of luck. [24:09.26]The same goes for tigers, sea lions, elephants.

[24:14.57]As the globe heats up and natural environments change,

[24:20.00]all big creatures are potentially at risk. But what about insects? [24:26.99]Some may be able to survive just about anywhere.

[24:31.84]But most insects are just as sensitive to climate change

[24:36.44]as their larger, more beloved animal relatives.

[24:41.77]What's more, insects are arguably more important than large mammals, [24:47.75]environmentally speaking. While several thousand polar bears wander the arctic,

[24:54.52]untold billions of insects live in virtually everywhere on Earth. [25:01.06]And they're essential in every ecosystem.

[25:05.52]For example, many of the world's crops and other plants

[25:10.98]rely on insects for pollination (授粉).

[25:14.69]In forests, insects help break down dead trees and prepare the soil for new growth.

[25:23.09]And there are the animals, like birds, that feed on insects.

[25:29.47]So how exactly will global warming affect insects?

[25:34.77]We don't really know. Some may go extinct.

[25:39.10]Others could migrate to cooler regions and wipe out native insect species there.

[25:46.76]And this could have all sorts of important implications for crops and entire ecosystems.

[25:55.71]What we do know is that because insects can't regulate their body temperature

[26:02.39]to the same degree as mammals, they're particularly sensitive to climate change.

[26:10.02]It's hard to predict what will happen to insects as the Earth warms. [26:16.38]But it looks like we're about to find out.

[26:22.35]Now the passage will be read again.

[26:25.28]It's well known that big animals, like polar bears,

[26:29.89]are sensitive to climate change.

[26:33.38]The Earth warms, polar ice melts, and the bears are out of luck. [26:39.41]The same goes for tigers, sea lions, elephants.

[26:44.56]As the globe heats up and natural environments change,

[27:02.03]But most insects are just as sensitive to climate change

[27:06.69]as their larger, more beloved animal relatives.

[27:11.89]What's more, insects are arguably more important than large mammals, [27:17.90]environmentally speaking. While several thousand polar bears wander the arctic,

[27:24.74]untold billions of insects live in virtually everywhere on Earth. [27:31.22]And they're essential in every ecosystem.

[27:44.93]In forests, insects help break down dead trees and prepare the soil for new growth.

[29:03.47]And there are the animals, like birds, that feed on insects.

[29:09.75]So how exactly will global warming affect insects?

[29:15.01]We don't really know. Some may go extinct.

[29:19.37]Others could migrate to cooler regions and wipe out native insect species there.

[30:36.90]And this could have all sorts of important implications for crops and entire ecosystems.

[30:52.42]to the same degree as mammals,

[32:05.48]they're particularly sensitive to climate change.

[32:10.08]It's hard to predict what will happen to insects as the Earth warms. [32:15.62]But it looks like we're about to find out.

[32:21.91]Now the passage will be read for the third time.

[32:25.97]It's well known that big animals, like polar bears,

[32:30.52]are sensitive to climate change.

[32:34.12]The Earth warms, polar ice melts, and the bears are out of luck. [32:40.01]The same goes for tigers, sea lions, elephants.

[34:46.32]But it looks like we're about to find out.

[34:52.36]This is the end of Listening Comprehension. [34:54.82]

For questions 1-7, choose the best answer from the four choices marked [A], [B], [C] and [D]. For questions 8-10, complete the sentences with the information given in the passage. Halloween On October 31st, dozens of children dressed in costumes knock on their neighbo rs’ doors and yell “Trick or Treat” when the door opens. Pirates and princesses, ghosts and popular heroes of the day all hold bags open to catch the candy or other goodies that the neighbors drop in. As they give each child a treat the neighbors exclaim over the costumes and try to guess who is under the masks. Since the 800’s November l st is a religious holiday known as All Saints’ Day. The Mass that was said on this day was called AllHallowmas. The evening before became known as All Hakkiwe’en, or Halloween. Like some other American celebrations, its origins lie in both pre-Christian and Christian customs. October 31st was the eve of the Celtic new year. The Celts were the ancestors of the present-day Irish, Welsh and Scottish people. On this day ghosts walked and mingled with the living, or so the Celts thought. The townspeople baked food all that day and when night fell they dressed up and tried to resemble the souls of the dead. Hoping that the ghosts would leave peacefully before midnight of the new year. Much later, when Christianity spread throughout Ireland and October 31st was no longer the last day of the year, Halloween became a celebration mostly for children. “Ghosts” went from door to door asking for treats, or else a trick would be played on the owners of the house. When millions of Irish people immigrated to the United States in the 1840s the tradition came with them. Today school dances and neighborhood parties called “block parties” are popular among young and old alike. More and more adults celebrate Halloween. They dress up like historical or political figures and go to masquerade parties(化装舞会). In larger cities, costumed children and their parents gather at shopping malls early in the evening. Stores and businesses give parties with games and treats for the children. Teenagers enjoy costume dances at their schools and the more outrageous the costume the better! Certain pranks (恶作剧) such as soaping car windows and tipping over garbage cans are expected. But partying and pranks are not the only things that Halloweeners enjoy doing. Some collect money to buy food and medicine for needy children around the world. Symbols of Halloween Halloween originated as a celebration connected with evil spirits. Witches flying broomsticks with black cats, ghosts, goblins (小精灵) and skeletons have all evolved as symbols of Halloween. They are popular trick-or-treat costumes and decorations for greeting cards and windows. Black is one of the traditional Halloween colors, probably because Halloween festivals and traditions took place at night. In

Model Test 3----参考答案部分

第三套模拟练习题参考答案作文参考范文 Information Security The human beings are stepping into the information society. The information industry develops very rapidly, so do the hackers, trick-playing teens, exploring children, fraudsters, and serious white-collar criminals. Thus, information security becomes an impending important issue. In case of information breach, the victims-----government department, an organization or an institution, or a company will inevitably suffer great or small loss. Government may be threatened with national security. Companies may lose opportunities to develop new projects. And the public’s and users’ confidence will be damaged. Then how to deal with this issue? Technology is only a partial solution to information security. What’s more important is that organizations and companies should promote the awareness on information security to its staff. However, since no system can ever be 100 percent secure, a prevention-only approach to information security management is not enough. Companies and organizations should adopt a dual approach to information security management by combing prevention and detection techniques. 快速阅读参考答案 1.

Model Test 1

Model Test 1 The shooting occurred Thursday in a lecture hall at Northern Illinois University in DeKalb , Illinois , north of Chicago. The gunman entered the hall dressed in black and carrying a shotgun and three handguns and began firing as students sought cover under desks. One student who escaped unharmed told reporter his life had changed as a result of what he experienced. Police say the gunman was Steven Kazmierczak,27, a former graduate student in Sociology at the school. Police say he purchased the shotgun and two of the handguns on Saturday, indicating he may have planned the attack in advance, but authorities have not determined a motive for the shooting. Kazmierczak had no criminal record and no history of mental illness. Under Illinois state law he would not been able to purchase a weapon legally if there had been a record of arrests or mental problems. But police say he stopped taking an unspecified medication recently and his behavior became erratic.
