The uses of computers

　　Not very long, the computer was a strange machine. Not many people understood it. Not many people said yes to it. Today much of that is changing. The first computer system(系统)was introduced for use in business in the mid-1950s. Since then, the number of computer systems used in business, government offices, and institutions has grown rapidly. In 1975, about 250,000 systems were in use in the United States. This is growing by tens of thousands every year.

　　The electric computer is an important factor(因素)in our lives. Each year we use computer more and more to help us to collect data(数据)and to provide us with information. At one time people thought computers were only useful to banks, department stores, and governments. But today the rapidly increasing number of computers are used for many other purposes. Have you ever stopped to think how you are affected(影响)by a computer? The clothes you wear were probably made with the help of a computer. The newspaper you read could have been edited(编辑)and typed by a computer. Even radio programmes are often prepared by computers.

　　Computers today are playing important roles(作用)in education, transportation(交通)and medicine. They are used to predict(预报)the weather, to examine the ocean, and to develop defense systems. They are being used by businesses, governments, and institutions. There is no reason to think that their uses will become a greater part of our lives.

　　The influence(影响)of the computer is great. The list of its uses could go on and on. Computers now affect millions of people in countless(无数的)ways every day.

The humorous story may be told to great length, and may wander around as much as it pleases, and arrive nowhere in particular; but the comic(滑稽的) story and the witty(诙谐的)story must be brief and end with a point. The humorous story continues gently along, the other two brusts.

The humorous story is strictly a work of art-high and delicate(精美的) art-and only an artist can tell it; but no art is necessary in telling the comic and witty stories; anybody can do it. The art of telling a humorous story-I mean by word of mouth, no print-was created in America, and has remained at home.

The humorous story is told seriously; the teller does his best to hide the fact that he himself even suspects(怀疑)that there is anything funny about it; but the teller of the comic story tells you before hand that it is one of the funniest things he has ever heard, then tells it with eager delight, and is the first person to laugh when he gets through. And sometimes, if he has had good success, he is so glad and happy that he will repeat the point of it and glance around from face to face, collecting applause(喝彩), and then repeat it again.

1．Which story takes the longest to tell?

[　　]

A．The humorous story.

B．The witty story.

C．The comic story

D．All three take the same amount of time.

2．Which story has no particular point?

[　　]

A．The humorous story.

B．The witty story.

C．The comic story

D．All three.

3．Which of the following statements is true?

[　　]

A．The humorous story was created abroad.

B．The humorous story is basically American.

C．The humorous story is also loved in other countries.

D．The humorous story is the least popular in the U.S.

4．The teller of a humorous story ________.

[　　]

A．laughs at his own joke

B．repeats it several times

C．is very serious when he tells it

D．is concerned about the reaction of his listeners

5．The teller of a comic story ________.

B．tells the listener in advance that his story is funny

C．doesn't care whether his listeners enjoy it or not

D．is very serious when telling it

THE WORLD'S NEW FACES

It will come as no surprise that the earth is going to be a much more crowded place in the next century. From global population of about 5.4 billion today, the United Nations Fund for Population Activities says we'll see a rise to 8.2 billion people in 2025. The U. N. expects total population to stabilize (稳定) at 11.6 billion sometime later in the 2000s. More than ninety percent of the population growth will occur in developing countries. Eighteen of the world's twenty largest cities will be in these lands as the number of urban dwellers (居民) swells (膨胀) from roughly two billion to 5.1 billion. The United States and Europe, which accounted for twenty-two percent of the world's population, will be home to less than nine percent of its people in 2025. By contrast (对照), Africa's share of the total will climb from nine percent in 1950 to nearly twenty percent by 2015. Ethiopia should double in size to almost 100 million people. In about the same time period, India will overtake China as the world's most-populous country.

　　 For the United States, the big news won't be an abundance (丰富，充裕) of new faces; experts predict (预言) the country will grow from its present 250 million population and stabilize at about 350 million sometime before the middle of the next century. The important changes will be in American ethnic (种族的) make-up. Twenty years from now, the United States' white, non-Hispanic (西班牙的) majority will peak (到达最高点) at 195 million, and then may decline in numbers. Asian-Americans will become an increasingly important minority, while African-Americans whose population growth rate is slowing dramatically will become the second largest minority behind Hispanics, a half-million of whom are now thought to be emigrating to the United States legally and otherwise, each year.

1.This article is primarily about ________

A. population growth in developing countries

B. population growth in developed countries
