A
Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines.
Some scientists have proposed setting a noise limit of one hundred and twenty decibels (分贝) in oceans. They have observed that noises at the level can frighten and confuse (使困惑) whales.
A team of American and Canadian scientists discovered that loud noises could seriously injure some animals. They found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales’ ability to exchange information and find their way. Some of the whales even died.
Some researchers whose work depends on ocean sounds object to (反对) a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research. Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists agree that noise is a greater danger than they believed. They want to prevent noises from harming creatures (生物) in the ocean.
56. According to the passage, which of the following is increasingly dangerous to sea creatures?
A. The man-made noises.
B. The noises made by themselves.
C. The sound of earthquakes.
D. The sound of ice-breaking.
57. Concerning the effect of noises on whales, which of the following is TRUE?
A. They are deaf to noises.
B. Noises at a certain level may hurt them.
C. Noises could kill them.
D. Noises will cause them to lose their eyesight.
58. Some scientists think that the noise limit of one hundred and twenty decibels would _________.
A. prevent them doing their research work
B. benefit them a lot in their research work
C. do good to their health
D. increase the industrial output
59. According to the last paragraph, what will scientists most probably do in the future?
A. They will study the effect of different noises in the sea.
B. They will work hard to make no noise.
C. They will never do any scientific research in the sea.
D. They will protect sea animals from harmful noises.

A
Too often we accuse others of not listening, pretending that we ourselves are faultless, yet in our hearts we know that many of the mistakes we make come about because we haven’t listened carefully enough. We get things wrong because we haven’t listened carefully enough. We get things wrong because we haven’t quite understood what someone meant when they were talking to us. Anyone who has ever taken the minutes of a long meeting will know how hard it is to remember-- despite the benefit of notes-- exactly what everyone said. But success depends on getting things right--and that means listening.
Listening is not the same thing as hearing; it is not an effort actively. It demands attention and concentration. It may mean quizzing the speaker for additional information or for clarification------ it is always better to ask than to continue regardless and get things wrong. However, if you allow your mind to wander onto something else, even for a few minutes, you’ll miss what the speaker is saying------ probably at the very moment when he or she is saying something critical. And not having heard, you won’t know you’ve missed anything until it’s too late.
The most common bad habit we have is to start thinking of what we are going to say about the subject long before the other speaker has finished. We then stop listening. Even worse, this often adds rudeness to inattentiveness, as once you have decided what to say there is a fair chance you will interrupt to say it. Good listeners don’t interrupt. In fact it is often worth explaining the main idea of what you have just been told before going on to make your own points. Nobody is offended by this and it shows that you have listened well.
Above all be patient and accept that many people are not very good communicators. It’s helpful to remember that the ways people move and position themselves while they are speaking can reveal a great deal about what they are saying. Equally important you should put yourself in the other person’s place, both intellectually and emotionally; it will help you to understand what they are getting at and form a response. But don’t be too clever. Faced with a know-all, many people keep quiet because they see no point in continuing.
56. Which is the best title for this passage?
A. Don’t be too clever B. Be a good listener.
C. Don’t miss anything critical D. Think of the speaker
57. In the last paragraph, “…… what they are getting at ……” means________ .
A. what they imply B. what they like
C. what they attack D. what they achieve
58. What is the writer’s opinion?
A. If you want to be a good listener, you should be very clever and emotional.
B. Speakers won’t continue talking when their listeners explain what they’ve heard.
C. If you don’t want to get things wrong, it’s important to be a good listener,
D. It’s hard to be a good listener because listening tests you on your intelligence.
59. What is the lesson we can learn from this passage?
A. Don’t accuse others of not listening while talking with them.
B. Don’t get anything wrong if you miss what the speaker is saying.
C. Listening inattentively may cost you the loss of your success.
D. Think carefully of what you’re going to say before the speaker finishes.
C
A long-awaited final report from the Food and Drug Administration (FDA) concludes that foods from healthy cloned animals and their offspring(后代) are as safe as those from ordinary animals, effectively removing the last US regulatory(监管的) barrier to the marketing of meat and milk from cloned cattle, pigs and goats.
The 968-page final report, not yet released but obtained by The Washington Post, finds no evidence to support people’s concerns that food from clones may have hidden risks.
But, recognizing that a majority of consumers are wary of food from clones—and that cloning could damage the good image of American milk and meat—the report includes hundreds of pages of raw(原始的) data so that others can see how it came to its conclusions.
The report also admits that human health concerns are not the only subject raised by the coming-out of cloned farm animals.
“Moral, religious and ethical concerns have been raised,” the agency notes in a document accompanying the report. But the report is “exactly a science-based evaluation.” It reports, because the agency is not authorized by law to consider those subjects.
In practice, it will be years before foods from clones make their way to store shelves in large quantities, in part because the clones themselves are too valuable to kill for meat or milk. Instead, the expensive animals—replicas(复制品) of some of the finest farm animals ever born—will be used firstly as breeding stock to create what supporters say will be a new generation of superior farm animals.
When food from those animals hits the market, the public may yet have its say. FDA officials have said they do not expect to require food from clones to be labeled as such, but they may allow foods from ordinary animals to be labeled as not from clones.
64. What can we infer from the first paragraph?
A. FDA has waited for a long time to get this final report.
B. Products from cloned animals have been put into the market before.
C. People are having the products from cloned animals safely.
D. There have been once opposite opinions against cloned products.
65. What does the underlined word “wary” mean?
A. Disappointed. B. Careful. C. Fond. D. Proud.
66. It will be a few years before foods from clones come into the market, partly because _____.
A. people have little knowledge of the cloned animals
B. supporters can’t give powerful evidence to support that
C. the few cloned animals will first be used to create superior animals
D. they are a new generation for the customers and are too valuable for the customers
67. What can we conclude from the passage?
A. FDA officials encourage people to eat more food from clones.
B. FDA officials think the food from clones will sell better than ordinary food.
C. People only worry about the health problems when it comes to foods from the clones.
D. All the foods will not have detailed labels on them.
The world is at a crossroads. The internet and new information technologies are so powerful that no matter what we do, society will change. But the direction has not been decided.
The internet it still in its infancy, but already we see fantastic things appearing as if by magic. Take Linux, the free computer operating system, or Wikipedia, the free encyclopedia. But where technology opens up new possibilities, our intellectual property laws do their best to restrict them. Linux is held back by patents, the rest of the examples by copyright. The public increasingly recognizes the need for reform.
Our manifesto(声明) is to reform copyright laws and gradually abolish(废除) the patent system. We oppose mass surveillance (监视)and censorship(审查制度) on the net, as in the rest of society. We intend to devote all our time and energy to protecting the basal civil liberties on the net and elsewhere.
Political decisions taken over the next five years are likely to set the course we take into the information society, and will affect the lives of millions for many years into the future. The information revolution is happening here and now. It is up to us to decide what future we want.
41. Which of the following statements is NOT true according to the passage?
A. Over the past decade, the volume of file-sharing has increased doubly.
B. Over the past decade, other peer-to-peer(对等网络) services have been beaten down.
C. Copyright laws should be reformed.
D. File-sharing occurs unless a file is sent on the Internet.
42. In the opinion of the writer, the government ________.
A. has to make a choice
B. should stop people sharing the copyrighted files
C. shouldn"t stop people sharing the copyrighted files
D. should monitor all the mail and all encrypted (加密) networks
43. The author"s main purpose in writing the passage is____________.
A. to have the basal citizen"s freedom on the net and elsewhere
B. to establish the patent system
C. to abolish copyright laws
D. to reform computer operating system
44. The underlined word “restrict” in Paragraph 3 most probably means__________.
A. remove B. limit C. close D. reform
45. We can infer from the passage_______________.
A. A new information revolution will be coming.
B. People won"t share copyrighted material on the net
C. People can share the free encyclopedia
D. The future of the Internet will rely on the government
Because a GPS has to receive a signal from space, physical impediments(遮挡) like skyscrapers, cliff faces, and even trees can stump(阻断) it. Reception is less of an issue with the ultrasensitive(超灵敏) chipsets in newer models, but if the walls are closing in on you, take a tip from a time when navigation systems weren"t the streamlined panels they are today: Hooking up an antenna(天线) will make use of even the most tenuous celestial connection. There"s a port on the back of most GPS devices for jacking in.
You"ll also want to remember that a GPS is not a compass: It runs on software. Like your PC, it needs to communicate with the mother ship periodically. Vendors(供应商) refresh firmware and maps on a regular basis, sometimes even daily. These updates deliver new bits of data that significantly affect your gadget"s accuracy. But if you live in the boonies(郊区) on a road named after your sister-wife, don"t expect NavTeq to come a-knocking with its survey equipment. Fortunately, most companies make it easy to update your own maps. Usually it"s as simple as plugging into your home computer, dropping a couple of pins in Google Maps, and clicking Save.
If you own a new Tom Tom, it"s even easier. You can edit maps on the unit itself, though you might not have to: Some of the company"s navigation updates themselves. Tom Tom"s IQ Routes software takes data from every person who uses the company" gadgets and readjusts its assumptions about which roads you should use and how long a given route will take. It will even change its own maps.
See, it"s not that hard: Your GPS may use NASA technology, but getting the most out of it isn"t rocket science.
46. The writer thinks the useful electronic partner is __
____besides a cell phone when driving outdoors.
A. a GPS B. Tom Tom"s IQ Routes C. a PC D. NASA
47. Which statement is NOT true about a GPS according to the passage?
A. It receives a signal from space.
B. It is not a compass.
C. It needs to refresh its information.
D. It has no port to connect other equipment.
48. You may learn from the passage that Tom Tom (Para 4) is _______.
A. a GPS receiver
B. a device that can be used to edit maps
C. a device that can be used to update software
D. a person who readjusts GPS assumptions
49. The main idea of the last paragraph is _______.
A. that we should make the most of GPS in rocket science
B. that getting the most out of GPS is too difficult
C. getting the most out of GPS is very easy
D. GPS owns NASA technology
50. Which is not mentioned about a GPS according to the passage?
A. Its usage. B. Its price and shape. C. Its technology. D. Its benefit.
B
A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increases the risk.
Research from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma (黑素瘤). They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma.
Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (发生率) faster than any other cancer in the United States.
But questions have been raised about sunscreen and whether it may have the opposite effect by allowing people to remain exposed to the sun longer without burning.
The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer---are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often.
The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.
60．The underlined word “flaws” in the 2nd paragraph most probably means _________.
A．evidences B．facts C．faults D．failures
61．People with fair skin and freckles ________.
A．seldom use sunscreen B．are more in danger of skin cancer
C．can be free from the harm of the sun D．often expose themselves to the sun
62．We can learn from the passage that _________.
A．sunscreen users get skin cancer more often
B．the volunteers have proved the effect of the sunscreen
C．the new study has based on the experiences of volunteers
D．the number of skin cancer patients is increasing in America
63．Which of the following is the best title of the passage?
A．Sunscreen to Prevent Skin Cancer B．Sunscreen to Increase Skin Cancer
C．Skin Cancer Caused by Sunscreen D．Skin Cancer Caused by Freckles
