From the beginning rivers have played an important part in the life of man. Man of the ear

liest times used the rivers as a means of traveling. Today rivers still serve as a great waterway for the transport and people.

In ancient times, man settled near rivers or on river banks and built up large empires.

Water is the Nature's most precious gift to man. Man needs water to irrigate his crops, to cook and to wash. In nations all over the world rivers mean life and wealth. They feed and clothe the nations around them.

Water is also a source of energy and power. Man constructs huge dams across the river to control the water for irrigation and get the energy needed to drive generators. The electrical power is then directed to homes, cities, factories and television stations.

Man uses water each day. His main source of water comes from reservoirs, which in turn get their water from the rivers.

Rivers also bring down soil and minerals from the mountains and deposit them on the plains building up rich river deltas for raising plants and crops. Fresh water life in rivers or in lakes fed by them provide man with food.

In a small way rivers help to keep man in good health and provide for his amusements. Various forms of water sports keep man strong and healthy.

Rivers have run on this earth long before man. Man's future ability to live is uncertain, but rivers will flow on forever.

Rivers have been important to man______.

A.since the last century

B.for a very long time

C.since a few hundred years ago

D.since a few years ago

For some employers, the policy of lifelong employment is particularly important because it
means that they can put money and effort into their staff(职员)training and make them loyal to the company. What they do is to select young people who have potential(潜能)and who can be trained, They then give the young people the kinds of skills that will make them suitable employees for the company. In other words, they adjust their training to their particular needs.

One recently employed graduate says that she is receiving a great deal of valuable training from the company. "This means that I will be a loyal employee,"she says, "And it also means that the company will want to keep me. I am an important investment for them. So the policy is a good one because it benefits both the employer and the employee. "

Recently, however, attitudes towards lifelong employment are beginning to change. Employees are slowly beginning to accept the idea that lifelong employment is not always in their best interest and that changing firms can have career advantages.

The purpose of lifelong employment is to______

A.adjust the needs of the company to its employees

B.make employees loyal to their company

C.select the best skilled young employees

D.keep the skilled staff satisfied

Few Americans remain in one position or one place for a lifetime. We moving from town to c
ity to suburb, from high school to college in a different state, from a job in one region to a better job elsewhere, from the home where we raise our children to the home where we plan to live in retirement. With each moving we are forever making new friends, who become part of our new life at that time.

For many of us summer is a special time for forming new friendships. Today millions of Americans vacation abroad, and they go not only to see new sights but also with the hope of meeting new people. No one really expects a vacation trip to produce a close friend, but the beginning of a friendship is possible.

The word "friend" can be applied to a wide range of relationships—to someone one has known for a few weeks in a new place, to a fellow worker, to a childhood playmate, to a man or woman, to a trusted confidant (知己) .

The reasons why many Americans move from place to place are as follows except______.

A.saving money

B.getting a better job

C.going to college

D.finding a place to spend the rest of the life

For years, studies have found that first-generation college students-those who do not have
a parent with a college degree-lag other students on a range of education achievement factors. Their grades are lower and their dropout rates are higher. But since such students are most likely to advance economically if they succeed in higher education, colleges and universities have pushed for decades to recruit more of them. This has created "a paradox" in that recruiting first-generation students, but then watching many of them fail, means that higher education has "continued to reproduce and widen, rather than close" achievement gap based on social class, according to the depressing beginning of a paper forthcoming in the journal Psychological Sciense.

But the article is actually quite optimistic, as it outlines a potential solution to this problem, suggesting that an approach(which involves a one-hour, next-to-no-cost program) can close 63 percent of the achievement gap(measured by such factors as grades)between first-generation and other students.

The authors of the paper are from different universities, and their findins are based on a study involving 147 students(who completed the project)at an unnamed private unive rsity.First generation was defined as not having a parent with a four-year college degree Most of the first-generation students(1 percent) were recipients of Pell Grants,a federal g rant for undergraduates with financial need,while this was true only for 8.6 percent of the students wit at least one parent with a four-year degree Their thesis-that a relatively modest inte rvention could have a big impact-was based on the view that first-gene ration students may be most lacking not in potential but in practical knowledge about how to deal with the issues that face most college students They cite past resea rch by several authors to show that this is the gap that must be na rrowed to close the achievement gap.

Many first-gene ration students"struggle to navigate the middle-class culture of higher education,learn the&39;rules of the game,&39;and take advantage of college resou rces," they write And this becomes more of a problem when collages don&39;t talk about the class advantage and disadvantages of different groups of students Because US colleges and universities seldom acknowledge how social class can affect students&39; educational expe rience,many first-gene ration students lack sight about why they a re struggling and do not unde rstand how students&39; like them can improve .

26. Recruiting more first-generation students has__________________

A.reduced their dropout rates

B.narrowed the achievement gao

C.missed its original purpose

D.depressed college students

The author of the research article are optimistic because__________________A.the problem is solvable

B.their approach is costless

C.the recruiting rate has increased

D.their finding appeal to students

The author of the paper believe that first-generation students__________________A.a re actually indifferent to the achievement gap

B.can have a potential influence on othe r students

C.may lack opportunities to apply for resea rch projects

D.are inexperienced in handling their issues at college

The study suggests that most first-gene ration students__________________A.study at private universities

B.are from single-pa rent families

C.are in need of financial support

D.have failed their collage

We mayinfer from the last paragraph that--A.universities often rect the culture of the middle-class

B.students are usually to blame for their lack of resources

C.social class g reatly helps en rich educational experiences

D.colleges are partly responsible for the problem in question

Since the early 1980s, scientists have revealed some 40 human genes involved in cancer. Th
ese genes are essential for normal growth, but can be subverted to cause a tumor.

Dr. Jorge Yunis of the University of Minnesota Medical School in Minneapolis has found that 70 percent of oncogenes, or cancer-causing genes, are located near inherited weak points on chromosomes(染色体). Varying from individual to individual, vulnerable to chemical carcinogens(致癌剂), X rays and other cancer-inducing agents.

"If a chromosome snaps apart in the immediate vicinity of an oncogene," says Yunis, "normal genetic control mechanisms could break down and the stage would be set for the formation of cancer." Younis has shown that such a sequence occurs at the beginning of numerous leukemias (白血病), lymphomas(淋巴瘤) and some tumors of the lung, colon(结肠) and breast.

Yunis and other investigators have found that petroleum-based products--notably pesticides and insecticides-damage specific sites on at least two of the 23 pairs of human chromosomes that carry genetic information. Similarly, tobacco smoke tends to attack a part of another chromosome.

From paragraph 1, we know that some 40 genes involving in cancer are ______. ()

A.harmful to the human body

B.necessary to the human body

C.the elements that form. cancer

D.useless to the human body

The student who wants a newspaper career has much hard work ahead of him before he can bec
ome even a cub, or beginning reporter. He may begin by working on his high school newspaper or yearbook.

Then the aspiring (有志的) reporter may break into newspaper work as a copyboy, running errands and helping sta. ff reporters. He may even be given a chance to write small stories. Sometimes students who are interested in news reporting can get jobs as campus reporters for local newspapers.

Jobs such as these serve to acquaint the beginner with the atmosphere of newsgathering. They give him a chance to sharpen his eye for details and teach him to be sure that his facts are accurate, that he reports them correctly, and that he writes his articles clearly. This work may lead to a job as a cub reporter on a newspaper, the important first step toward a career in news reporting.

The best title for this passage is ______.

A.The Work of a Newspaper Reporter

B.Reporting News from the Campus

C.Getting Started as a Reporter

D.What a Copyboy Does

第11题
Although each baby has an individual schedule of development, general patterns of growth h
ave been observed. Three periods of development have been identified (确定) , including early infancy (幼儿期) , which extends from the first to the sixth month; middle infancy, from the sixth to the ninth month; and late infancy, from the ninth to the fifteenth month. Whereas the newborn is concerned with his or her inner world and reacts primarily to hunger and pain in early infancy, the baby is already aware of the surrounding world. During the second month, many infants are awake more and can raise their heads to look at things. They also begin to smile at people. By four months, the baby is searching for things but not yet grasping them with its hands. It is also beginning to be wary(谨慎的) of strangers and may scream when a visiting relative tries to pick it up. By five months, the baby is grabbing objects and putting them into its mouth. Some babies are trying to feed themselves with their hands.

In middle infancy, the baby concentrates on practicing a great many speech sounds. It loves to imitate actions and examine interesting objects. At about seven months, it begins to crawl, a skill that it masters at the end of middle infancy.

In late infancy, the baby takes an interest in games, songs, and even books. Progress toward walking moves through standing, balancing, bouncing in place, and walking with others. As soon as the baby walks well alone, it has passed from infancy into the active toddler (蹒跚学步) stage.

What is the main subject of this reading passage?

A.Growth in early infancy.

B.The active toddler.

C.How a baby learns to walk.

D.The developmental stages of infancy.
