听力原文: Nothing can buy a better night's sleep. Although it sounds silly, it was the fir
st thing that crossed my mind when I awoke. I truly appreciated my happy rest. It was like a gift from heaven. Interesting to think that Bill Gates, or any rich men you can mention, really couldn't have had a more satisfying and grateful night of sleety--the best that money can't buy.

That started me thinking of other pleasures that cost nothing or very little and that are often taken for granted, like a drink of cold water on a hot day when you're really thirsty, or a warm relaxing bath when you're extremely tired or mentally exhausted.

Remember your first real kiss--can you put a price tag on that? Or the companionship of a faithful and loving pet or the clean, fresh smell of mountain air? There's an old song, "the Best Things in Life Are Free."

Did you ever eat a meal that not only filled your stomach and satisfied all your tastes, but refreshed your soul? Ever spend a winter's evening in the company of good friends?

What could be better than listening to your favorite music or watching a good movie? Or sharing the beauty of a sunset with a loved one? These are quite delightful and delicate pleasures. I hope this doesn't sound too ridiculous in today's rough, loud world. I hope the new generation can appreciate some of these things.

(33)

A.The writer enjoys sleeping very much.

B.Bill Gates does not know how to enjoy himself.

C.The writer doesn't like money at all.

D.Mental well-being is the most important thing.

听力原文:M: Are you looking forward to your trip to Canada, Susan?

W: I can't wait to see Canada, Jason, but I'm scared stiff of the journey. My husband insists on flying, but I want to sail. Planes make me nervous.

M: There's nothing to be frightened of. How many planes fly across the Atlantic every day?

W: I've no idea. Hundreds, I suppose.

M: And how often do you hear of a crash? Once or twice a year?

W: Yes, but aero-planes fly so high and fast that once is enough.

M: There are more road accidents per day than air deaths per year. Air transport is really safe compared with road transport.

W: I still prefer to go by sea. Ships may not travel fast but as least you can relax. I'd love a trip on a luxury liner like the Queen Elizabeth II.

M: It's fine if you're a good sailor, but have you ever traveled far in a rough sea?

W: No. I've only been in a boat once. I sailed down the River Thames on a sightseeing tour, but in any case I'd rather be sea-sick than dead.

What is the woman afraid of when she takes her trips?

A.Taking a voyage.

B.Taking a train.

C.Taking a flight.

A close analogy to a study design is the rough sketch made by an artist before he commits
his vision to canvas(画布). The broad outlines are drawn, the proper perspective achieved, and the total impact of the picture-to-be can be partially appreciated in advance. So it is with the design of research: it specifies in advance the kinds of statements that can be made on the basis of its findings and fixes the perspectives against which these findings are to be evaluated.

One major purpose of this study was to demonstrate whether or not the newer social re search techniques could help in broadening and deepening knowledge concerning juvenile delinquency(少年犯罪). Construction of the design was guided by this goal of exploring new methods ill the analysis of juvenile delinquency. However, research technique developed in one content area can not be mechanically transferred to another. A new application of them requires substantial changes and it is these innovative modifications which this study offers as its contribution.

Juvenile delinquency has been the subject of many previous studies using a variety of re search techniques. This study makes an additional contribution by using a design specially planned to permit a comparison of several approaches.

The drawing-up of the study design profited greatly from an extensive survey of previous researches on crime, undertaken during the earliest stage of the project. It was found that most studies could be classified as belonging to one or more of three broadly conceived types: social background study, family background study and personal motivation study.

Each type has its characteristic design and mode of interpretation and each has produced information of considerable importance. Yet no attempt was made in any of the studies to integrate one or more of these three design types. It became apparent that one of the major contributions a pilot study could make to both method and substantive findings would be to bring all three study types together in one design for the purpose of correlating(使相互关联) their find rugs and evaluating their relative importance in producing data of use to the practitioner.

In the first paragraph, the author draws an analogy between ______.

A.doing research and drawing a picture

B.research finding and picture perspective

C.designing a research and making a quick drawing

D.a researcher and a painter

听力原文:In one way of thinking, failure is a part of life. In another way, failure may be

听力原文: In one way of thinking, failure is a part of life. In another way, failure may be a way towards success. The "spiderstory" is often told. Robert Bruce, leader of the Scots in the 13th century, was hiding in a cave from the English. He watched a spider spinning a web. The spider tried to reach across a rough place in the rock. He tried six times to span the gap. On the seventh time, he made it and went on to spin his web. Bruce is said to have taken heart and to have gone on to defeat the English.

Edison, the inventor of the light bulb, made hundreds of models that failed before he found the right way to make one. Once he was asked why he kept on trying to make a new type of battery when he had failed so often. He replied,

"Failure? 1 have no failures. Now, I know 50,000 ways that it won' t work."

So what? First, always think about your failure. What caused it? Were conditions right? Were you in top form. yourself? What can you change so that things may go right next time?

Second, is the goal you're trying to reach the right one? Try to do some titivating about what your real goals may be. Think about this question, "If I do succeed in this, where will it gel me?" This may help you prevent failure in things you shouldn' t be doing anyway.

The third thing to bear in mind about failure is that it's a part of life. Learn to live with yourself even though you may have failed. Remember, you can't win them all .

(33)

A.Failure and success.

B.The "spider-story".

C.Two sides of failure.

D.The invention of the light bulb.
