Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings. The noise that affects sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.
Decibels(分贝) measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibel level of one hundred and ninety-five would have the same effect.
Some scientists have suggested setting a noise limit of one hundred and twenty decibels in oceans. They have observed that noises at that level can frighten and confuse whales.
A team of American and Canadian scientists discovered that loud noises can seriously injure some animals. The research team 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. The explosions had caused their ears to bleed and become infected.
Many researchers whose work depends on ocean sounds object to 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 suspect that noise is a greater danger than they believed. They want to prevent noise from harming creatures in the ocean.
45.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

47. As to the influence of noises on whales, which of the following statements is TRUE?
A. They are deaf to noises. B. Noises at a certain level may hurt them.
C. They are easily confused by noises D. Noises will limit their ability to reproduce
48. According to the passage, what will scientists most probably do in the future?
A. They will try their best to decrease noise.
B. They will work hard to cut down noise pollution.
C. They will study the effect of different noises.
D. They will protect animals from harmful noises.

When I was about 12, I had an enemy, a girl who liked to point out my shortcomings. Week by week her list grew: I was very thin, I wasn’t a good student, I talked too much, I was too proud, and so on. I tried to bear all this as long as I could. At last, I became very angry. I ran to my father with tears in my eyes.
He listened to me quietly, and then asked. “Are the things she says true or not? Jane, didn’t you ever wonder what you’re really like? Well, you now have that girl’s opinion. Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said.”
I did as he told me. To my great surprise, I discovered that about half the things were true. Some of them I couldn’t change (like being very thin), but a good number I could – and suddenly I wanted to change. For the first time I got a fairly clear picture of myself.
I brought the list back to Daddy. He refused to take it. “That’s just for you,” he said. “You know better than anyone else the truth about yourself. But you have to learn to listen, not just close your ears in anger and feeling hurt. When something said about you is true, you’ll find it will be of help to you. Our world is full of people who think they know your duty. Don’t shut your ears. Listen to them all, but hear the truth and do what you know is the right thing to do.”
Daddy’s advice has returned to me at many important moments. In my life, I’ve never had a better piece of advice.
41.Which do you think would be the best title for this passage?
A. Not an Enemy, but the Best Friend B. The Best Advice I’ve Ever Had
C.My Father D. My Childhood
42.What does “Week by week her list grew” mean?
A. Week by week she discovered more shortcomings of mine and pointed them out to me.
B. She had made a list of my shortcomings and she kept on adding new ones to it so that it was growing longer and longer.
C. I was having more and more shortcomings as time went on.
D. Week by week, my shortcomings grew more serious.
43.Why did her father listen to her quietly?
A. Because he believed that what her daughter’s “enemy” said was mostly true.
B. Because he had been so angry with his daughter’s shortcomings that he wanted to show this by keeping silent for a while.
C. Because he knew that his daughter would not listen to him at that moment.
D. Because he wasn’t quite sure which girl was telling the truth.
44. What did the father do after he had heard his daughter’s complaint?
A. He told her not to pay any attention to what her “enemy” had said.
B. He criticized her and told her to overcome her shortcomings.
C. He told her to write down all that her “enemy” had said about her and pay attention only to the things that were true.
D. He refused to take the list and have a look at it.

At one time, computers were expected largely to remove the need for paper copies of documents because they could be stored electronically. But for all the texts that are written, stored and sent electronically, a lot of them are still ending up on paper.
It is difficult to measure the quantity of paper used as a result of use of internet-connected computers, although just about anyone who works in an office can tell you that when e-mail is introduced, the printers start working overtime. “I feel in my bones this revolution is causing more trees to be cut down,” says Ted Smith of the Earth Village Organization.
Perhaps the best sign of how computer and internet use pushes up demand for paper comes from the high-tech industry itself, which sees printing as one of its most promising new markets. Several internet companies have been set up to help small businesses print quality documents from a computer. Earlier this week Hewlett-Packard Co. announced a plan to develop new technologies that will enable people to print even more so they can get a hard copy of a business document, a medical record or just a one-line e-mail, even if they are nowhere near a computer. As the company sees it, the more use of the internet the greater demand for printer.
Does all this mean environmental concerns have been forgotten? Some activists suggest people have been led to believe that a lot of dangers to the environment have gone away. “I guess people believe that the problem is taken care of, because of recycling,” said Kelly Quirke, director of the Rainforest Action Network in San Francisco. Yet Quirke is hopeful the high-tech may also prove helpful. He says printers that print on both sides are growing in popularity. The action group has also found acceptable paper made from materials other than wood, such as agricultural waste.
57.The growing demand for paper in recent years is largely due to _______.
A.the rapid development of small businesses B. the opening up of new markets

D. to plant more fast-growing trees
59.Hewlett-Packard Co. has decided to develop new technologies because ________.
A. people are concerned about the environment
B. printers in many offices are working overtime
C. small companies need more hard copies
D. they see growing market for printers
60. What would be the best title for the text?
A. Computers and Printers B. E-mail and the Business World
C. Internet Revolution and Environment D. Modern Technology and New Markets

Illegal removal of coral(珊瑚) along Sri Lanka’s coastline increased the amount of destruction on the island by last December’s tsunami, say researchers.
Harindra Fernando, a fluid dynamicist (力学家) at Arizona State University in Tempe, made the connection after a visit to his native Sri Lanka earlier this year．While serving as a scientific expert and translator for a BBC-documentary team, he chatted with locals who said they saw the tsunami turn sideways when it hit coral—which would have made it less powerful than in coral-free areas．Fernando linked this to trucks he had seen last year carrying piles of coral away from the sea.
Using the eyewitness reports, estimates (估算) of wave heights, and a series of divers to check the presence or absence of corals, Fernando and his colleagues produced a map of coral gaps and wave flooding along Sri Lanka’s southwest coast.
The tsunami reached significantly farther inland through the gaps: in one instance, the water traveled 1.5 kilometres long and knocked a passenger train off its tracks, killing 1,700．But only a few kilometers away, where the coral was still undamaged, the wave travelled just 50 metres inland and caused no deaths.
There is a similar phenomenon．In Nicaragua in 1992, a tsunami poured through a break in the coral reef made to let boats through．“Within this passage, water went one kilometre inland,” says Fernando．“But nearby, where the coral was undamaged, there were still beach umbrellas standing.”
In Sri Lanka, coral is illegally mined to provide souvenirs for tourists, or to be used in house paint．Coral harvesters sometimes blow it up with dynamite (炸药) in order to collect fish at the same time．Often, the reefs in the best shape are those in front of hotels, as the hotel owners maintain them for the tourists．Fernando hopes that his findings will encourage the Sri Lankan government to enforce(实施) its laws against coral mining.

A．serving as a translator for a BBC-documentary team
B．helping the Sri Lankan government enforce its laws against coral mining

B．coral-free area is a danger to passenger trains
C．in general, water travels 30 times farther inland in a coral-free area
D．it is urgent to enforce laws against coral mining
59．Which of the following may NOT be the cause of coral gaps?

60．Which of the following would be the best title for the passage?
A．Harindra Fernando, a Great Environment Protector
B．Stop Using Coral as Souvenirs
C．Coral Cried “Help! Help!”
D．Coral Mining Enhanced (加剧) Tsunami Damage

Coal mine accidents are frequently headline makers in China, offering a plentiful supply of long lists of the dead．Before this, five major coal mine accidents since January have already claimed lives of 287 coal miners.
Once an accident happens, the safety measures are scrutinized, officials and owners responsible are punished or warned or fined．But the accidents keep happening time and again.
The background of this endless disaster is a country thirsty for energy to satisfy the appetite of its economic engine.
With the rich reserve（储存）of coal and relatively limited petroleum（石油）reserve, the former makes up 67.12 percent of energy consumption．By contrast, petroleum and natural gas take about 60 percent of the energy consumption in other countries.
Such a situation is unlikely to change within a foreseeable future because the country still counts heavily on coal for more and more energy．If no measures with great effects are taken to improve the safety in the mines, the accidents will remain a long-term headache for China.
Digging coal underground is, by its nature, a dangerous job．No equipment can guarantee 100 percent safety for the miners working underground because numerous uncertainties exist.
Most of China’s coal mines are far from being mechanized．The average output of coal for each Chinese coal miner every day is 1 ton, while the number in the US coal mines, where the production is highly mechanized, is 40 tons.
Mechanized production in coal mines can cut down the number of miners who have to work on the dangerous coal face．It can also enhance the capability of the mines to detect potential danger．In this way mine accidents will be decreased.
Admittedly, the mechanized production demands financial support.
But what is the price of a life, or a dozen, a score – a hundred? Compare these awful figures with the misery they bring, heavy investment is worthy.
53．The writer’s attitude towards dealing with coal mine accidents is ________．
A．critical B．positive C．unclear D．doubtful
54．The underlined word “scrutinized” most probably means ________．
A．made B．examined C．criticized D．discussed
55．According to the writer, the best way to stop coal mine accidents is to ________.
A．perfect safety measures B．use more natural gas
C．cut down the number of miners D．improve mechanized production
56．The writer implies in the article that ________.
A．by improving mechanized production, we can stop coal mine accidents
B．it’s improper to depend too much on coal for energy consumption
C．officials and coal mine owners didn’t take safety measures seriously
D．losing lives costs much more than improving mechanized production

A．private evening tutoring	B．selfstudy at home
C．longhour study	D．school study

A．the attitude	B．the schooling time
C．star pupils	D．new teaching approach
