Some scientists say that animals in the oceans 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(分貝)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 proposed 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 louder 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 noises from harming creatures in the ocean.
小題1: 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 the ice-breaking.
小題2: Which of the following is discussed in the third paragraph?
A.Different places with different types of noises.
B.The very human ears sensitive to all types of noises.
C.The ocean animals' reaction to noises.
D.The same noise measured differently on land and in the ocean.
小題3:We can know from the passage that many researchers think that the noise limit of one hundred twenty decibels would _____.
A.prevent them from doing their research work
B.benefit them a lot in their research work
C.do good to their health
D.increase the industrial output
小題4: 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.

Animals are natural resources that people have wasted all through our history.
Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the world forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.
Why should people care? Because we need animals. And because once they are gone, there will never be any more.
Animals are more than just beautiful and interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems.
For example, when farmers killed large numbers of hawks(老鷹), the farmers stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep down their numbers, the rats and mice multiplied(繁殖) quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger.

When coal is burned in a boiler, two kinds of ash by-products are produced: a heavy bottom ash and a fine-as-powder fly ash. About 10 to 15 percent of the coal by-product is bottom ash which is used like sand on streets and highways covered with ice, and also on highways as paving material.
It is the fly ash, however, that is receiving much attention. Once considered a waste, fly ash is now regarded as a natural resource in the United States. It can be placed in some lower places, where it is compacted and covered with soil, for the seeds of various grasses and plants to be placed in the soil to make the land productive.
Fly ash may be added to concrete to build roads and other kinds of buildings, taking the place of the cement up to 20 percent. As a by-product of burned coal, fly ash requires no extra energy to be produced, while cement production requires great amounts of energy.
Besides, the technology is able to take out some useful minerals from the fly ash, which is still a very expensive process today. But the time may come when it is cheaper to take out these products from ash than to mine new supplies.
小題1: The bottom ash can be put on icy streets________.
A.in order to rebuild themB. in order to make them colourful
C.so that people can walk on themD.so that cars can run faster
小題2:The fly ash_______ bottom ash.

C.has more uses thanD.is much cheaper than
小題3:The fly ash can be used to________.
A.grow various plantsB. take the place of soil
C.cover productive landD.make more productive land

A.To produce fly ash, some extra coal is to be burned.
B. Fly ash is made while producing cement.
C.It takes less energy to produce fly ash than cement.
D.Fly ash is a costless by-product.
小題5:The word “mine” in the last sentence of the passage means_______.

Raymond Schneider politely elbowed his way through crowds of customers as he made for the candy bins at Dylan’s Candy Bar in Manhattan. Since he was laid off in December, Mr. Schneider, a 33-year-old designer, says he has become a “gummy junkie,” buying a lot of sweets every time he shops for groceries.
“Sugar is comforting,” he said. “There’s nothing more stressful than growing financial insecurity everywhere.”
The recession (經(jīng)濟衰退) seems to have a sweet tooth. As unemployment has risen, Americans, particularly adults, have been consuming growing amounts of candy, say candy makers, store owners and industry experts.
Theories vary on exactly why. For many, sugar lifts spirits dragged low by the economy. For others, candy also provides a reminder of better times. And not insignificantly, it is relatively cheap.
At Candyality, a store in the Lakeview neighborhood of Chicago, business has jumped by nearly 80 percent compared with this time last year, and the owner, Terese McDonald, said she was struggling to keep up with the demand for Bit-O-Honeys, Swedish Fish and Sour Balls.
“They put candy in their actual budget,” she said.
Many big candy makers are also reporting rising sales and surprising profits.
“Candy companies are relatively recession-proof,” said Peter Liebhold, chairman of the Smithsonian Institution’s work and industry division. “During the Great Depression, candy companies stayed in business.”
小題1:Raymond Schneider was set as an example to show ________.
A.many Americans were laid off in the recession
B.lots of Americans like candies
C.many Americans in the recession like sweets which are comforting
D.Americans are suffering much in the recession.
小題2: What does the underlined sentence “The recession seems to have a sweet tooth” mean?
A.Candy consuming rises while people are suffering bad effects of the recession.
B.The recession doesn’t have any bad effect on Americans.
C.Americans are optimistic even though they are out of employment.
D.Candy companies stayed in business during the Great Depression.
小題3:Which is NOT the reason why people in the recession like sugar?
A.It is relatively cheap.
B.It is comforting and can make a lot of profits.
C.It raises people’s spirits up.
D.It calls up people’s good memories.
小題4: The best title of the passage is ________.
A.Sugar Is Comforting
B.Candy Companies Stay In Business
