完型填空It seems quite clearly unjust to pay two people different amounts of money for doing the same work. But it is not as easy as it appeals at first __1__ to introduce equal pay for equal work. Two people may be working side by side in a factory and doing the same work, but one may be doing it twice as fast as the __2__; or one may be making no mistakes, while the other is making a lot. In some kinds of work, one can solve the problem of speed if one pays by the amount of work to be done and not by the hour: work paid for in this __3__ is called piece-work. But it is not always possible to do this, so it is sometimes useful to pay workers at different rates, which take differences in skill into __4__. This usually means that the younger and therefore less experienced worker gets less than the __5__ and more experienced one, which seems reasonable enough.

听力原文： In the field of marketing, consumer goods are classed according to the way in which they are purchased. The two main categories are convenience goods and shopping goods. Two lesser types are specialty goods and unsought goods.
People do not spend much time shopping for convenience items such as groceries, newspapers, toothpaste, razor blades, aspirin, and candy. The buying of convenience goods may be done routinely, as some families buy groceries once a week. Such regularly purchased items are called staples. Sometimes convenience products are bought on impulse, for example, someone has a sudden desire for an ice cream sundae on a hot day. Or they may be purchased as emergency items.
Shopping goods are items for which customers search. They compare prices, quality, and styles, and may visit a number of stores before making decisions. Buying an automobile is often done this way.
Shopping goods fall into two classes: those that are perceived as basically the same and those that are regarded as different. Items that are looked upon as basically the same include such things as home appliances, television sets, and automobiles. Having decided on the model desired, the customer is primarily interested in getting the item at the most favorable price. Items regarded as inherently different include clothing, furniture, and dishes. Quality, style. and fashion will either take precedence over price, or they will not matter at all.
Specialty goods have characteristics that impel customers to make special efforts to find them. Price may be no consideration at all. Specialty goods can include almost any kind of product. Normally, specialty goods have a brand name or other distinguishing characteristics.
Unsought goods are items a consumer does not necessarily want or need or may not even know about. Promotion or advertising brings such goods to the consumer's attention. The product could be something new on the market or it may be a fairly standard service, such as life insurance, for which most people will usually not bother shopping.
According to the speaker, what are convenience goods？
A．Commodities that people are in constant need of.
B．Goods that are convenient to use or purchase.
C．Items that people tend to buy under impulse.
D．Items that have to be bought once a week.

A scientist who wants to predict the way in which consumers (消费者) will spend their money must study consumer behavior. He must obtain data both on the resources of consumers and on the motives that tend to encourage or discourage money spending.
If an economist were asked which of three groups borrow most — people with rising incomes, stable incomes, or decreasing incomes—he would probably answer, those with decreasing incomes. Actually in the years 1947 ~ 1950, the answer was: people with rising incomes. People with decreasing incomes were next and people with stable incomes borrowed the least. This shows us that traditional assumptions (假设) about earning and spending are not always reliable. Another traditional assumption is that if people who have money expect prices to go up they will hasten to buy. If they expect prices to go down, they will postpone buying. But research surveys have shown that this is not always true.
The expectations of price increases may not stimulate buying. One typical attitude was expressed by the wife of a mechanic in an interview at a time of rising prices. "In a few months, "she said, "we' 11 have pay more for meat and milk; we' 11 have less to spend on other things. "Her family had been planning to buy a new car but they postponed this purchase. Furthermore, the rise in prices that has already taken place may be disliked and buyer's resistance may be produced. This is shown by the following typical comment; "I just don't pay these prices; they are too high. " The investigations mentioned above were carried out in America; The condition most helpful to spending appears to be price stability. If prices have been stable and people consider that they are reasonable, they are likely to buy. Thus, it appears that the common business policy of maintaining stable prices is based on a correct understanding of consumer psychology (心理学) .
According to the passage, if one wants to predict the way spend their money, he should
A．rely on traditional assumptions about earning and spending
B．try to encourage or discourage consumers to spend money
C．carry out investigations on consumer behavior. and get data on consumers incomes and money spending motives
D．do researches in consumer psychology in a laboratory

A friend of mine had this problem and handled it in the most tactful (得体的) way I've ever seen. Instead of telling her admirer directly, she devoted herself to introducing him to every girl she knew. Whenever she had a date with him, she arranged to drop in at the home of one of her girl friends. At last he clicked (一见如故) with one of these girls, and then everyone was happy. My friend was rid of a problem and she still had the young man as a friend, which was just what she wanted him to be.
Of course this solution may not work for you. You may have your own way of dealing with the problem. But whatever you decide to do, keep one thing in mind—the boy in question has feelings every bit as sensitive as your own. So try to find a way of discouraging him without hurting him.
The best title for this passage would be______.
A．How to Make a Friend
B．Problems of Dating
C．Good Advice for Girls
D．How to Free Yourself from an Admirer

听力原文： Most of us have an image of such a normal or standard English in pronunciation, and very commonly in Great Britain this is "Received Pronunciation", which is often associated with the public schools, Oxford, and the BBD. At the same time, it must be remembered that so far as the English-speaking countries are concerned, this "Received Pronunciation" approached the status of a "standard" almost only in England. Educated Scots, Irishmen, Americans, Australians, and others have their own different images of a standard form. of English.
Even in England it is difficult to speak of a standard in pronunciation. Pronunciation is infinitely variable, so that even given the will to adopt a single pronunciation, it would be difficult to achieve. There is no sure way of any two people saying the same word with precisely the same sound. In this respect pronunciation much more closely resembles handwriting than spelling. In spelling, there are absolute distinctions which can be learnt and imitated with complete precision: One can know at once whether a wont is spelt in a standard way or not. But two person' s handwritings and ciations may both be perfectly intelligible，yet have obvious differences without out being able to say which is“better”or more“standard”．

A．English pronunciation, spelling and handwriting.
B．The status of Received Pronunciation in the English-speaking countries.
C．The difficulty of achieving a standard in English pronunciation.
D．The importance of achieving a standard in English pronunciation.

Crocodiles(鳄鱼)lay their eggs and leave them under leaves or sand. Baby crocodiles have special sharp teeth with which to break their way out of the shells. Crocodiles only live where it is hot. They are found in India, Australia, Africa and America. They spend most of their time lying around in the mud or the rivers. The crocodiles long powerful tail is used when the animal is swimming. It is also an excellent weapon, because it can be swung with great speed and force. One blow will knock down a man or even a big animal at once. The crocodile is very well protected against its enemies by the hard bony plates which cover most of its body, but because of the way its neck is formed, it cannot turn its head from side to side and so it can only see in front of itself. The crocodile has its teeth cleaned by the crocodile bird. For its food this bird takes the bits left in the crocodiles mouth. This helps the crocodile, which cannot clean its own teeth, for it cannot move its tongue up and down. With its rows of terrible pointed teeth it seizes its food, which may be a fish, an animal, or even a careless human being, and then holds it below the water until it is drown to death. The long-nosed crocodile is shy and timid and because of this, the people of West Africa where it lives, sometimes catch it for food. Many, many centuries ago there were crocodiles in England. We know this because we have found their bones buried far down in the earth on which London is built. But the Britain of today is too cold for them to live in. Crocodiles may grow to over thirty feet in length. When they lie floating in the water, they look like floating tree-trunks and it is often impossible to tell that they are there.
The female crocodile______.
A．buries her eggs
B．sits on her eggs
C．carries her eggs
D．eats her eggs

But I do not agree with the opinion that women have to show their beauty through their looks. The richness of their mind proves to be more beautiful and attractive than their looks. A woman who has experienced many troubles and may be called "aunt" or "granny" can still maintain her beauty if she has such excellent qualities as knowledge, ability, a kind heart and concern for others.
In addition, old and young, beautiful and ugly are relative concepts. People who keep a young mind will never feel old. Curious about new things and eager to learn more, they keep up with the tide. Plainly dressed women may have a type of beauty, which is pure and real.
Reading and learning is the best way to keep one youthful. Good books are fertile soil which can feed the flower of one's heart and looks.
Why does the author say that beauty and women are twins？
A．Women are born to be beauties.
B．Women like to show off their beauties
C．Women are proud of their beauty
D．Women try to maintain their beauty by dressing up

Good music expresses feelings in a way that is suitable to those feelings. There may be joy, sorrow, fear, love, anger, or whatever. Bad music, on the other hand, may confuse unrelated feelings. It may not express any important feeling at all, or it may exaggerate some feelings and make them vulgar, that is, cheap and ugly.
Good music will stand the test of time. It will not go out of fashion but will continue to be enjoyed and respected long after it is first introduced. It will gain a kind of permanent status while bad music will disappear and be forgotten quickly. In pop music, where the general rule seems to be" the newer, the better" , the test of time is the hardest test of all to pass.
A piece of original music ______.
A．has a personal style
B．sounds very familiar to our ears
C．is one whose style. you cannot recognize
D．can not be recognized as belonging to any composer
