t live up to the manufacturer'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's favor, assuming he or she has a just claim.

Consumers should 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.

When a consumer finds that his purchase has a fault in it, the first thing he should do is to ______.

A．complain personally to the manager

B．threaten to take the matter to court

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

D．show some written proof of the purchase to the store

听力原文： The most prestigious exchange in the world is the New York Stock Exchange (NYSE). The NYSE is the first type of exchange, where much of the trading is done face-to-face on a trading floor. This is also referred to as a "listed" exchange. Orders come in through brokerage firms that are members of the exchange and flow down to floor brokers who go to a specific spot on the floor where the stock trades. At this location, known as the trading post, there is a specific person known as the "specialist" whose job is to match buyers and sellers. Prices are determined by using an auction method: the current price is the highest amount any buyer is willing to pay and the lowest price at which someone is willing to sell.

Passage Three

Questions 31 to 35 are based on the following passage.

The physicist investigating the relationship between time and space, the chemist exploring the properties of a new substance, the biologist probing the mysteries of the continuity of life. and the anthropologist(人类学家)searching for human origins share a common trait(特征), curiosity. Not that nonscientist are not curious；most people possess this characteristic. The scientist, however, uses a specific method to make researches into these enigmatic(难以理解的)problems-the scientific method.

Unfortunately, science and its method are misunderstood, the multiplication of our knowledge in medicine and technology has led to the idea that science can cure all and explain all and that only enough time, money and intelligence are needed. In truth. science cannot provide all answers. In fact, many phenomena are not even subject to scientific explanations.

On the other side of the coin, science has been attacked as a cause of most contemporary problems. It is said to be responsible for the depersonalization(使失去个性)of the individual, for stripping(夺去)creativity from human behavior, and for creating massive threats to the species through the development of nuclear power, insecticides, and polluting machinery. If we analyze the situation, we can see that it was not the original intent of the people who developed computers to debase humankind, nor was mass production proposed as a method to crush creativity. It is what society, policymakers especially, does with scientific achievements that makes them social or antisocial. There is nothing inherently good or bad about science.

Which of the following is the main topic of the passage？

A. Scientists and their curiosity.

B. Science and scientific method.

C. Understandings of science.

D. Misunderstandings of science.

A.For

B.Even if

C.Though

D.Since

A man who knows a bit about carpentry (木工术) will make his table more quickly than the man who does not. If the instructions are not very clear, or the shape of a piece is puzzling his experience helps him to conclude that it must fit there, or that its function must be that. In the same way, the reader's sense and experience helps him to predict what the writer is likely to ,say next; that he must be going to say this rather than that. A reader who can think along with the writer in this way will find the text.

This skill is so useful that you may wish to make your students aware of it so that they can use it to tackle difficult texts. It does seem to be the case that as we read we make hypotheses (假设) about what the writer intends to say; these are immediately modified by what he actually does say, and are replaced by new hypotheses about what will follow. We have all had the experience of believing we were understanding a text until suddenly brought to a halt by some word or phrase that would not fit into the pattern and forced us to reread and readjust our thoughts. Such occurrences lend support to the notion of reading as a constant making and remaking of hypotheses.

If you are interested in finding out how far this idea accords with (符合) practice, you may like to try out the text and questions. To do so, take a piece of card and use it to mask the text. Move it down the page, revealing only one

t a time. Answer the question before you go on to look at the next section. Check your prediction against what the text actually says, and use the new knowledge to improve your next prediction. You will need to look back to earlier parts of the text if you are to make accurate prediction, for you must keep in mind the general organization of the argument as well as the detail within each sentence. If you have tried this out, you have probably been interested to find how much you can predict, though naturally we should not expect to be right every time -- otherwise there would be no need for us to read.

Conscious use of this technique can be helpful when we are faced with a part of the text that we find difficult: if we can see the overall pattern of the text, and the way the argument is organized, we can make a reasoned guess at the next step. Having an idea of what something might mean can be a great help in interpreting it.

The author uses the examples of carpentry and reading to show______.

A．the importance of making prediction

B．the similarity in using one's senses

C．the necessity of making use of one's knowledge

D．the most effective method in doing anything

f, especially to your own children. But how you say it can be quite tricky.

If you say to your children "I'm sorry I got angry with you, but...", what follows that "but" can render the apology ineffective: "I had a bad day" or "your noise was giving me a headache" leaves the person who has been injured feeling that he should be apologizing for his bad behavior. in expecting an apology.

Another method by which people appear to apologize without actually doing so is to say "I'm sorry you're upset"; this suggests that you are somehow at fault for allowing yourself to get upset by what the other person has done.

Then there is the general, all covering apology, which avoids the necessity of identifying a specific act that was particularly hurtful or insulting, and which the person who is apologizing should promise never to do again. Saying "I'm useless as a parent" does not commit a person lo any specific improvement.

These pseudo-apologies are used by people who believe saying sorry shows weakness. Parents who wish to teach their children to apologize should see it as a sign of strength, and therefore not resort to these pseudo-apologies.

But even when presented with examples of genuine contrition, children still need help to become aware of the complexities of saying sorry. A three-year-old might need help in understanding that other children feel pain just as he does, and that hitting a playmate over the head with a heavy toy requires an apology. A six-year-old might need reminding that spoiling other children's expectations can require an apology. A twelve-year-old might need to be shown that raiding the biscuit tin without asking permission is acceptable, but that borrowing a parent's clothes without permission is not.

If a mother adds "but" to an apology, ______.

A．she doesn't feel that she should have apologized

B．she does not realize that the child has been hurt

C．the child may find the apology easier to accept

D．the child may feel that he owes her an apology
