第1题

Not all trips are holidays. For example, when people travel on business, they don't have t

he time or the peace of mind to enjoy themselves. But when people take a vacation, do they always have fun？

The fact is some people who travel for pleasure get no pleasure from it at all. Others, who travel because they must travel, have a lot of fun doing it. What makes one trip more enjoyable than another？

Any trip can be enjoyable if it is well planned. Every minute that you spend planning your trip may save ten minutes of trouble during your trip. It may also add an hour of pleasure!

Many resorts and cities around the world are popular during some months of the year and less popular during other months. Find out if the places you are visiting have an "in" season and an "off" season. This may help you decide when you want to go.

There are some very good reasons to travel during the off-season. Usually everything is much cheaper. It is also less crowded, of course. If you don't have a lot of money or if you don't like crowds of tourists go in the off-season.

Some places are not as exciting during the off-season. The weather may be too cold or too hot. The beaches may be closed. Hotels and restaurants may be shut. Be sure to find out before you go.

There was a time when a person could decide to leave the country on Monday and get on a boat on Tuesday. Now everyone must give a passport to go abroad. It is not hard to get a passport, but you should ask for one a few months before you begin your journey. To get one, you must have your birth certificate or another legal document to prove that you are a citizen. You will probably also need to bring a few photographs of yourself and some money. For more information call or write the passport office.

Sometimes you need a visa to visit a country. If a visa is necessary you can ask for one at the country's embassy. Sometimes getting a visa takes many months, so it is very important to plan early. The same is true of health certificates. For this information it is a good idea to call or write the embassies. You may also get a lot of other useful information from them.

What can we learn from the first two paragraphs？

A．When people travel on business, they are also on holiday.

B．When people take a vacation, they always have fun.

C．Not all people on holiday get pleasure from it.

D．All trips are holidays.

Over 60 million persons in the United States own a credit card. For these millions of Americans a credit card is "coined freedom". It has had effect of increasing consumption possibilities for households by allowing them to purchase thousands of dollars of merchandise. ranging from autos. clothing, to electrical appliances. The widespread use of creditcard nowadays staggers the imagination to the point where one wonders whether the total amount of consumption spending each year would be the same if this "plastic money" were not around, Credit cards have also been of significant importance to the national economy.Businessmen have been encournged to expand plant and equipment and hire additionat personnel to meet the heavy demand for their products, The tendency of employment and income would rise significantly. Unfortunately the ease with which buyers can increase their purchase with credit cards have caused them to overlook the additional costs.Purchase on credit cards are postponed payments. Buy-now pay later encourages buyers to use credit cards ,extencively.Since the buyer is in effect borrowing money for a special purposer he must expect to pay an interest charge.

One of the arguments against the use of credit cards has been that those who do pay cash at the time if purchase finance the use of a credit card by another person.This is so, the argument runs, because the price of a product will include the cost of another persons use of a credit card.

A new report of the United Nations shows that, if the present growth rate of 2 percent per

year continues, today's world population of 5.1 will hit 6.4 billion by the year 2000.

What's more, the great part of the growth—9 of every 10—added to the earth's population—will be in the poor and undeveloped countries. These are the nations where providing enough food for billions of people already is proving to be a headaching problem.

By the year 2000, today's "have not" nations will have a total population of 5 billion people, nearly four-fifths of the world's population.

Food isn't the only problem that such a population explosion presents. The more people there are and the worse their living conditions, the greater grow the possibility of all kinds of social problems.

In 1830, world population reached 1 billion. It took only 100 more years to add another billion to world population, just 30 more to add a third billion. And it took just 15 more years to reach the 4 billion mark in 1975.

Actually, the world's birth rate is falling. But so is death rate, as medical advances have made it possible for man to live longer than before. Such advances have also reduced baby death rate. Unless population growth is reduced, the world population may reach 12 billion in a century. Is the earth capable of providing a good life for so large a population？

A population explosion will lead to______.

A．a lot of social problems

B．medical advances

C．a decrease in food production

D．a worse life in every country

根据以下资料，回答10~13题。 We first think of the traditional or nuclear family．This is a

two-generation family, the father and the mother and their own children．Most couples wanted to have four children, two boys, two girls. Some nuclear families, however, may add one or more grandparents to come to live with them, that is three generations．This kind of family with grandparents, parents, and grandchildren is called an extended family．This family type was not very common during the later half of the twentieth century, but it's becoming more common now as an elderly grandparent moves in to live with a son or daughter．This is more possible now that American homes have become larger．What is interesting, however, is that after the grandchildren move out of the home and start their own families, this extended family shrinks back to a nuclear family, with just two generations again living together, a grandparent and parents, with the grandchildren coming only for occasional visits． Now, the fatherless or motherless family is one kind of what we call a single-parent family．In the fatherless family it's just the mother and her children．As I said, this can be the result of the husband's death, of an unmarried mother, of a separation or divorce．There are also a growing number of motherless families--where the father raises the children, for any of the same reasons．A motherless family may also be fatherless, but still a family with one adult．This is becoming more common in the big cities where a grandmother will raise her daughter's children while the daughter goes elsewhere to work. One other new kind of family is becoming increasingly more common．A single parent with one or more children will marry again．Perhaps the other parent is also a single parent．Together they will start what is called a blended family, which blends together or combines the children from two other families. Who usually looks after the children in a both motherless and fatherless family in America？ A．The children's aunt. B．The children's nursery or school． C．The children's grandmother. D．The children's neighbour.

听力原文： What do we mean by a satisfactory standard of living？ Obviously, it must include

the basic necessities of life such as food, clothing and shelter.

To obtain these necessities on a regular basis, a person must have a reliable income. But we have other needs which we would probably also describe as basic, for example, health and education facilities and security.

All of these we may define as our needs. But most of us would be far from satisfied if we had nothing more than these provided for us. We all enjoy having extra income to spend on things such as books, sports, or hobbies. Sometimes we save some of this extra income to provide for future expenditure of this type on holidays, for example. So in addition to our basic needs, we must add our wants. Our standard of living is the degree to which these needs and wants are satisfied.

Why are we far from satisfied with our basic needs？

A．Because we should save extra money for future expenditure.

B．Because we have other wants in addition to our basic needs.

C．Because we all enjoy reading books.

D．Because man is never satisfied even if he has everything he wants.

A.Volcanic clay call be found in very few countries．

B.Non-volcanic clay can be dried more quickly．

C.Non-volcanic clay makes better containers．
