These are two important questions that many people are asking today. Some people think that man might be able to solve both problems at the same time. They suggest using garbage as an energy source, and at the same time it can save the land to hold garbage.

For a long time, people buried garbage or dumped(倾倒it on empty land. Now, empty land is scarce. But more and more garbage is produced each year. However, garbage can be a good fuel to use. The things in garbage do not look like coal, petroleum, or natural gas; but they are chemically similar to these fossil(化石fuels. As we use up our fossil fuel supplies, we might be able to use garbage as an energy source.

Burning garbage is not a new idea. Some cities in Europe and the United States have been burning garbage for years. The heat that is produced by burning garbage is used to boil water. The steam that is produced is used to make electricity or to heat nearby buildings. In Paris, France, some power plants burn almost 2 million metric tons of the cities garbage each year. The amount of energy produced is about the same as would be produced by burning almost a half mil- lion barrels of oil.

Our fossil fuel supplies are limited. Burning garbage might be one kind of energy source that we can use to help meet our energy needs. This method could also reduce the amount of gar-bage piling up on the earth.

What two problems can man solve by burning garbage?

A.The shortage of energy and air pollution.

B.The shortage of energy and the land to hold garbage.

C.Air pollution and the shortage of fossil fuel.

D.Air pollution and the shortage of land to hold garbage.

Which of the following is not the result of burning garbage?A.The garbage burned is turned into fossil fuels.

B.The heat produced is used to boil water.

C.The steam produced is used to make electricity.

D.The steam produced is used to heat buildings.

According to the passage which of the following is NOT true?A.About 2 million metric tons of garbage is burned in some power plants in Pads, France each year.

B.In a modem society, more and more garbage is produced each year.

C.Using garbage is a good way to solve the problem of energy shortage.

D.It will be too expensive to use garbage as an energy source.

What is the author's attitude?A.Delighted.

B.Sad.

C.Agreeing.

D.Disagreeing.

The best title for the passage may beA.Garbage and the Earth

B.Fossil Fuel and Garbage

C.Land and Garbage

D.Garbage--Energy Source

more than that? For example, suppose a friend wants to borrow some money from you, you say: I wish I could help you but I&39;m short of money myself. In fact, you are not short of money, but your friend is in the habit of not paying his debts and you don&39;t want to hurt his feelings by reminding him of this. Is this really a lie?

A scientific study of lying shows women are better liars than men, particularly when telling a "white lie" such as when a woman at a party tells another woman that she likes her dress when she really thinks it looks terrible. However, this is only one side of the story. Other researches show that men are more likely to tell more serious lies, such as making a promise which they have no intention of fulfilling. This is the kind of lie politicians and businessmen are supposed to be particularly skilled at: the lie from which the liar hopes to profit or gain in some way.

Research has also been done into the way people&39;s behavior. changes in a number of small, apparently unimportant ways when they lie. It has been found that if they are sitting down at the same time, they tend to move about in their chairs more than usual. To the trained observer they are saying I wish I were somewhere else now.

ot live up to the manufacturer&39;s claim for it, the first step is to present the warranty(保单, or any other records which might help, at the store of purchase. In most cases, this action will produce results. However, if it does not, there are various means the consumer may use to gain satisfaction.

A simple and common method used by many consumers is to complain directly to the store manager. In general, the "higher up" the consumer takes his or her complaint, the faster he or she can expect it to be settled. In such a case, it is usually settled in the consumer&39;s favour, assuming he or she has a just claim.

Consumers shoud complain in person whenever possible, but if they cannot get to the place of purchase, it is acceptable to phone or write the complaint in a letter.

Complaining is usually most effective when it is done politely but firmly, and especially when the consumer can demonstrate what is wrong with the item in question. If this cannot be done, the consumer will succeed best by presenting specific information as to what is wrong, rather than by making general statements. For example, "The left speaker does not work at all and the sound coming out of the right one is unclear" is better than "This stereo(立体声音响does not work."

The store manager may advise the consumer to write to the manufacturer. If so, the consumer should do this, stating the complaint as politely and as firmly as possible. But if a polite complaint does not achieve the desired result, the consumer can go a step further. She or he can threaten to take the seller to court or report the seller to a private or public organization responsible for protecting consumers,rights.

A.complain personally to the manager

C.write a firm letter of complaint to the store of purchase

Tthe passage tells us _____.A.how to settle a consumer's complaint about a faulty item

t they now pollute soil, water, and food, that they have the power to make our streams fishless and our gardens and woodlands silent and birdless. Man, however much he may like to pretend the contrary, is part of nature. Can he escape a pollution that is now so thoroughly distributed throughout our world?

We know that even single exposures to these chemicals, if the amount is large enough, can cause extremely severe poisoning. But this is not the major problem. The sudden illness or death of farmers, farm workers, and others exposed to sufficient quantities of pesticides is very sad and should not occur. For the population as a whole, we must be more concerned with the delayed effects of absorbing small amounts of the pesticides that invisibly pollute our world.

Responsible public health officials have pointed out that the biological effects of chemicals are cumulative over long periods of time, and that the danger to the individual may depend on the sum of the exposures received throughout his lifetime. For these very reasons the danger is easily ignored. It is human nature to shake off what may seem to us a threat of future disaster. "Men are naturally most impressed by diseases which have obvious signs," says a wise physician, Dr.Rene Dubos, "yet some of their worst enemies slowly approach them unnoticed."

Which of the following is closest in meaning to the sentence "Man, ... is part of nature."(Line 3,Para.1)?

A.Man appears indifferent to what happens in nature.

B.Man acts as if he does not belong to nature.

C.Man can avoid the effects of environmental pollution.

D.Man can escape his responsibilities for environmental protection.

What is the author's attitude towards the environmental effects of pesticides?A.Pessimistic.

B.Indifferent.

C.Defensive.

D.Concerned.

In the author's view, the sudden death caused by exposure to large amounts of pesticides _____.A.is not the worst of the negative consequences resulting from the use of pesticides

B.now occurs most frequently among all accidental deaths

C.has sharply increased so as to become the center of public attention

D.is unavoidable because people can't do without pesticides in farming

People tend to ignore the delayed effects of exposure to chemicals because _____.A.limited exposure to them does little harm to people's health

B.the present is more important for them than the future

C.the danger does not become apparent immediately

D.humans are capable of withstanding small amounts of poisoning

It can be concluded from Dr.Dubos'remarks that _____.A.people find invisible diseases difficult to deal with

B.attacks by hidden enemies tend to be fatal

C.diseases with obvious signs are easy to cure

D.people tend to overlook hidden dangers caused by pesticides
