Though the facts that too many people on earth and a too rapid increase in the number added each year are not in argument, we always begin the discussion of "population as global issue" with what most persons mean like this. It was quite right to compare demographic growth to "a long, thin powder fuse(导火线)that bums steadily and hesitatingly until it finally reaches the charge and explodes".
To understand the current situation, which is characterized by rapid increases in population, it is necessary to understand the history of population trends. Rapid growth is a comparatively recent phenomenon. Looking back at the 8,000 years of demographic history, we find that populations have been virtually stable or growing very slightly for most of human history. For most of our ancestors, life was hard, often nasty, and very short. There was high fertility(生育)in most places, but this was usually balanced by high mortality. For most of human history, it was seldom the case that one in ten persons would live past forty, while infancy and childhood were especially risky periods. Often, societies were in clear danger of extinction because death rates could exceed their birthrates. Thus, the population problem throughout most of history was how to prevent extinction of the human race.
This pattern is important to notice. Not only does it put the current problems of demographic growth into a historical perspective, but it suggests that the cause of rapid increase in population in recent years is not a sudden
enthusiasm for more children, but an improvement in the conditions that traditionally have caused high mortality.
Demographic history can be divided into two major periods: a time of long, slow growth which extended from about 8000 B.C. till approximately 1650 A.D. In the first period of some 9,600 years, the population increased from some 8 million to 500 million in 1650. Between 1650 and 1975, the population has increased from 500 million to more than 4 billion. And the population reached 6.2 billion throughout the world by the year 2000, One way to appreciate this dramatic difference in such abstract numbers is to reduce the time frame to something that is more manageable. Between 8000 B.C. and 1650, an average of only 50,000 persons was being added annually to the world's population, At present, this number is added every six hours. The increase is about 800000,000 persons annually.

Sub-Saharan Africa has the world’s highest hunger rate. But according to a new report, African farmers also have ideas that could help the world fight hunger and poverty. Danielle Nierenberg from the Worldwatch Institute in Washington spent a year visiting twenty-five countries south of the Sahara. In Nairobi, Kenya, for example, Ms Nierenberg found women farmers growing vegetables just outside their doorsteps in the Kibera settlement. She says they are finding ways to make their lives better. The women feed their families and sell their surplus. They use the money to send their children to school.
Last year, about 925,000,000 people worldwide did not get enough to eat. Half of all people in the world now live in and around cities. Researchers like Ms Nierenberg are looking increasingly at creative ideas to feed those who don’t have enough good food to eat. She says there are a lot of lessons that people in the Western world can learn from Africa. And what they are doing can certainly be done in other developing countries.
Farmers in the developing world lose between twenty and forty percent of their harvest before it ever reaches market. There are many reasons why food gets wasted. Farmers are without electricity and cold storage. They lack good seeds and fertilizer. They lack good roads. Conditions like these keep small farmers in poverty. Ms Nierenberg says more attention needs to be paid to protecting harvests. She says, “Given all that we invest in producing food in the first place, we need to devote the same amount of attention to making sure that it is not wasted.”
In Nigeria, village processing centers are helping farmers reduce their losses and earn more money. They centers process cassava, a root vegetable, into basic food products. In Uganda, the Worldwatch report says some schools are teaching children how to grow local kinds of crops. And in South Africa and Kenya the report praises the breeding(培育) of local kinds of livestock. These animals may produce less milk or meat than other breeds, but they can survive heat and drought conditions.We could learn from the new report in Para.1 that .
| A．sub-Saharan Africa has the world’s highest hunger rate |
| B．African farmers have ideas to help fighting hunger and poverty |
| C．women farmers grow vegetables in the Kibera settlement |
| D．women farmers grow vegetables to send their children to school. |
The underlined word “surplus” in Para.1 is closest in meaning to .

I never thought I would have a life-changing experience at Wal-Mart.
Although my thoughts were only on speed, the checkout line I was standing in wasn't moving as quickly as I wanted, and I glanced toward the cashier.
There stood a man in his seventies, wearing glasses and a nice smile. I thought, well, he's an old guy!
For the next few minutes I watched him. He greeted every customer before scanning the items. Sure, his words were the usual, "How's it going?" But he did something different--he actually listened to people. Then he would respond to what they had said and engage them in brief conversation.
I thought it was odd. I has grown accustomed to people asking me how I was doing simply out of robotic conversational habit. After a while, you don't give any thought to the question and just mumble something back. I could say, "I just found out I have six months to live," and someone would reply, "Have a great day!"
But that wasn't the end.
He gave them the change, walked around the counter, and extended his right hand in an act of friendship. He looked the customers in the eyes. "I sure want to thank you for shopping here today," he told them. "You have a great day. Bye-bye."
The looks on the faces of the customers were priceless. There were smiles and some sheepish grins. All had been touched by his simple gesture--and in a place they never expected. They would gather their things and walk out, smiling.
Of course, he did the same to me and I got to know his name--Marty.

| B．He might have died while working in the market. |

Hospital emergency rooms treat injured fingers all the time. Without treatment, a bad cut can lead to permanent damage. But how should a person know when a bleeding cut is serious enough to require medical attention? We asked Dr Martin Brown, chairman of the department of emergency medicine at Inova Alexandria Hospital in Virginia.
First, the medical term for a cut or tear in the skin is a laceration(严重划破，撕裂伤). Dr Brown says the length is usually not as important as the depth. He says a long cut on a finger can likely be treated without a visit to a doctor if the wound is not very deep. “If you have a short but deep laceration where there’s been a structure underneath that’s been damaged － a tendon, a nerve, a blood vessel,” says Martin, “it may, in fact, need professional attention.”
Some injuries － like a fingertip that gets cut off － might even require surgery to repair. That requires a specialist to either file(锉平) down the bone or reattach the fingertip. More often, filing down the bone is what is done because reattaching a fingertip is often not successful.
How a wound bleeds can be a sign of how serious it is. Minor cuts usually produce what is known as venous (静脉) bleeding. This means the blood flows steadily from the injury. The bleeding will often stop when pressure is put on the wound. Dr Brown says in most cases holding direct pressure with clean gauze or a cloth for four to five minutes should stop the bleeding. With a cut finger, holding the hand above the heart can reduce the loss of blood. But if a cut appears to be pumping blood out with some force, this may be a sign of arterial(动脉) bleeding. This kind of injury should be treated by a medical professional as soon as possible.
Even a cut that does not require medical attention must be kept clean to prevent infection. Small cuts should be cleaned gently with clean water. Use a washcloth to clean the area if the wound is dirty. Dr Brown says cuts should be covered with a clean, dry bandage.What does the writer want to tell the readers in the first paragraph?
| A．Hospital emergency rooms always treat injured fingers. |
| B．A bleeding cut is serious enough to require medical attention |
| C．Dr Martin Brown is in charge of Inova Alexandria Hospital. |
| D．It is important for us to be able to tell how serious a finger cut is. |

The way people hold to the belief that a fun-filled, pain free life equals happiness actually reduces their chances of ever attaining real happiness. If fun and pleasure are equal to happiness then pain must be equal to unhappiness. But in fact, the opposite is true: more often than not things that lead to happiness involve some pain.
As a result, many people avoid the very attempts that are the source of true happiness. They fear the pain inevitably brought by such things as marriage, raising children, professional achievement, religious commitment, self-improvement.
Ask a bachelor why he resists marriage even though he finds dating to be less and less satisfying. If he is honest he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure , excitement. Marriage has such moments, but they are not its most distinguishing features.
Couples with infant children are lucky to get a whole night’s sleep or a three-day vacation. I don’t know any parent who would choose the word fun to describe raising children. But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild.
Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations. It liberates time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those who are always having so much fun actually may not be happy at all.Raising children, in the author’s opinion, is .
| A．a moral duty | B．a thankless job |
| C．a rewarding task | D．a source of inevitable pain |

To understand what true happiness is, one must .
A have as much fun as possible during one’s lifetime
B. make every effort to liberate oneself from pain
C. put up with pain under all circumstances
D .be able to distinguish happiness from funFrom the last paragraph, we learn that envy sometimes results from .
| A．hatred | B．misunderstanding |
| C．prejudice | D．ignorance |

| A．How to get happiness |
| B．Happiness often goes hand in hand with pain |

New technology links the world as never before. Our planet has shrunk. It’s now a “global village” where countries are only seconds away by fax or phone or satellite link. And, of course, our ability to benefit from this high-tech communications equipment is greatly increased by foreign language skills.
Deeply involved with this new technology is a kind of modern businesspeople who have a growing respect for the economic value of doing business abroad. In modern markets, success overseas often helps support domestic business efforts.
Overseas assignments (指派) are becoming increasingly important to advancement within executive (行政) ranks. The executive stationed in another country no longer need fear being “out of sight and out of mind.” He or she can be sure that the overseas effort is central to the company’s plan for success, and that promotions often follow or accompany an assignment abroad. If an employee can succeed in a difficult assignment overseas, superiors will have greater confidence in his or her ability to manage back in the United States where cross-cultural considerations and foreign language issues are becoming more and more common.
Thanks to a variety of relatively inexpensive communications devices (装置) with business applications, even small businesses in the United States are able to get into international markets.
English is still the international language of business. But there is an ever-growing need for people who can speak another language. A second language isn’t generally required to get a job in business, but having language skills gives a candidate the edge when other qualifications appear to be equal.
The employee posted abroad who speaks the country’s language has an opportunity to fast-forward certain negotiations, and can have the cultural insight (洞察力) to know when it is better to move more slowly. The employee at the home office who can communicate well with foreign customers over the telephone or by fax machine is an obvious asset (有价值的人或物) to the firm. With the increased use of high-tech communications equipment, businesspeople ________.
| A．are eager to work overseas |
| B．have to get familiar with modern technology |
| C．are gaining more economic benefits from domestic operations |
| D．are attaching more importance to their overseas business |
In this passage, “out of sight and out of mind” (Line 3, Para. 3) probably means ________.
| A．leaving all care and worry behind |
| B．being unable to think properly for lack of insight |
| C．being totally out of touch with business at home |
| D．missing opportunities for promotion when abroad |
According to the passage, what is an important consideration of international corporations in employing people today?
| A．Ability to speak the customer’s language. |
| B．Connections with businesses overseas. |
| C．Technical know-how. |
| D．Business experience. |
The advantage of employees having foreign language skills is that they can ________.
| A．fast-forward their proposals to headquarters |
| B．better control the whole negotiation process |
| C．easily make friends with businesspeople abroad |
| D．easily find new approaches to meet market needs |
