Studies show that the world in 2010 will be more crowded，more polluted and less stable ecologically(在生态方面)than the world we live in now.Visible ahead is serious stress involving population，resources and environment.Despite greater food output，people in the world will be poorer in many ways than they are today.For hundreds of millions of the extremely poor，the outlook for food and other necessities of life will be no better.For many it will be worse.While the economies of the developing countries are expected to grow at a faster rate than those of the industrialized nations，the total national product per head in most less developed countries remains low.The existing gap between the rich and poor nations will further widen.World food production is estimated to increase by 90 percent from 1970 to 2010.Most of that increase goes to the countries that already have relatively higher per-head food consumption(消费).Meanwhile，per-head consumption of food in the developing countries will scarcely improve or will actually fall far below the present inadequate level.What is worse is prices for food are expected to double.As a result，many less developed countries will have increasing difficulties meeting energy needs.For the one quarter of mankind that depends primarily on wood for fuel，the outlook is not hopeful.Regional water shortage will become more severe.In the 1970-2010 period population growth will require twice as much water as it does today in nearly half the world.Still greater increases would be needed to improve standards of living.Development of new water supplies will become more costly.
1. According to the passage，in 2010 while output of food will be greater，___.
A. people will have sufficient food supplies
B. the world resources will become more than enough
C. in most developing countries people will have less food than they have today

A. to 90 percent
B. to developing countries
C. to any country in the world that needs it
D. to those countries that already have high per head consumption
4. How does the author predict the development of new water supplies in the future_
A. Water shortage will occur in some regions only.
B. Development of new water supplies will be more expensive.

Smoking
Since 1939, numerous studies have been conducted to determine whether smoking is a health hazard. The trend of the evidence has been consistent and indicates that there is a serious health risk. Research teams have conducted studies that show beyond all reasonable doubt that tobacco smoking is associated with a shortened life expectancy.
Cigarette smoking is believed by most research workers in this field to be an important factor in the development of cancer of the lungs and cancer of the throat and is believed to be related to cancer of some other organs of the body. Male cigarette smokers have a higher death rate from heart disease than non-smoking males. Female smokers are thought to be less affected because they do not breathe in the smoke so deeply.
Apart from statistics, it might be helpful to look at what tobacco does to the human body. Smoke is a mixture of gases, vaporized chemicals, minute particles of ash and other solids. There is also nicotine, which is powerful poison, and black tar. As smoke is breathed in, all those components from deposits on the membranes of the lungs. One point of concentration is where the air tube and bronchus divides. Most lung cancer begins at this point.
Filters and low tar tobacco are claimed to make smoking to some extent safer, but they can only slightly reduce, not eliminate the hazards.
It is easy to determine whether smoking is hazardous.
A．Right
B．Wrong
C．Not mentioned

Will it matter if you don' t take your breakfast？ Recently a test was given in the United States. Those tests included people of different ages, from 12 to 83. During the experiment, these people were given all kinds of breakfasts, and sometimes they got no breakfast at all. Special tests were set up to see how well their bodies worked when they had eaten a certain kind of breakfast. The results show that if a person eats a proper breakfast, he or she will work with better effect than if he or she has no breakfast. This fact appears to be especially true if a person works with his brains. If a student eats fruit, eggs, bread and milk before going to school, he will learn more quickly and listen with more attention in class. Contrary to what many people believe, if you don't eat breakfast, you will not lose weight. This is because people become so hungry at noon that they eat too much for lunch, and end up gaining weight instead of losing. You will probably lose more weight if you reduce your other meals.
The results of the test show that______.
A．breakfast has great effect on work and studies
B．breakfast has much to do with people's health
C．a person will work better if he has simple breakfast
D．breakfast only affects those who work with their brains

In the United States 84 colleges now accept just women. Most of them were established in the 19th century; they were designed to offer women the education they could not receive anywhere else. At that time major univ ersities and colleges accepted only men. In the past 20 years many young women have chosen to study at colleges that accept both men and women. As a result, some women’s colleges decided to accept men students too.

Others, however, refused to change. Now these schools are popular again.

e president of Smith College in Massachusetts says a women’s college permits women to choose classes and activities freely. For example, she says that in a women’s college, a higher percentage of students study mathemat ics than in a college with men and women.

Educational experts say men students in the United States usually speak in class more than women students do. In a women’s college, women feel freer to say what they think. Women’s schools also bring out leadership ca pabilities in many women. Women are represented everywhere. For example, at a women’s college every governing office is held by a woman. Recent studies reportedly show that this leadership continues after college. The studies show American women who went to women’s colleges are more likely to hold successful jobs later in life.

41、Women’s colleges were established to（）.

A.give women the same right to education that men enjoy

B.make changes to traditional educational system

C.defy men’s privilege in the society

D.train women in particular fields

42、Studying at the same school with men does not mean that（）.

A.women can do the same thing as men

B.women are given the same chance as men

C.women are allowed more freedom to develop themselves

D.the present educational system does not allow other choices

43、According to the passage, in women’s schools（）.

A.women are much freer than if they study at the same school with men

B.women could do anything they want

C.they teach things peculiar to women

D.men are hated widely

44、Which of the following is NOT true about women’s college?（）

A.Women feel freer to say what they think.

B.More women can participate in the management of the college.

C.Women who attend a women’s college are more likely to be successful in their later careers.

D.A very high percentage of women will become leaders later.

　　In the United States, 30 percent of the adult population has a weight problem. To

　　many people, the cause is obvious: they eat too much. But scientific evidence does little to

　　support the idea.

　　Going back to the America of the 1910s, we find that people were thinner than today,

　　yet they ate more food. In those days people worked harder physically, walked more, used

　　machines much less and didn’t watch television.

　　Several modern studies, moreover, have shown that fatter people do not eat more on

　　average than thinner people. In fact, some investigations, such as the 1979 study of 3,545

　　London office workers, report that, on balance, fat people eat less than slimmer people.

　　Studies show that slim people are more active than fat people. A study by a research

　　group at Stanford University School of Medicine found the following interesting facts:

　　The more the men run, the more body fat they lost. The more they ran, the greater amount

　　of food they ate. Thus, those who run the most ate the most, yet lost the greatest amount of

　　body fat.

　　11. The physical problem that many adult Americans have is that ________.

　　A. they are too slim B. they work too hard

　　C. they are too fat D. they lose too much body fat

　　12. According to the article, given 500 adult Americans, ________ will have a weight

　　problem.

　　A. 30 B. 50 C. 100 D. 150

　　13. Is there any scientific evidence to support that eating too much is the cause of a weight

　　problem？

　　A. Yes, there is plenty of evidence.

　　B. Of course, there is some evidence to show this is true.

　　C. There is hardly any scientific evidence to support that.

　　D. We don’t know because the information is not given.

　　14. In comparison with the adult American population today, the Americans of the 1910s

　　_______.

　　A. ate more food and had more physical activities.

　　B. ate less food but had more activities

　　C. ate less food and had less physical exercise

　　D. had more weight problems

　　15. Modern scientific researchers have reported to us that ________.

　　A. fat people eat less food and are less active

　　B. fat people eat more food than slim people and are more active

Human's Hands Archaeological records--paintings, drawings, and carvings of humans engaged
Human's Hands
Archaeological records--paintings, drawings, and carvings of humans engaged in activities involving the use of hands--indicate that humans have been predominantly right - handed for more than 5,000 years. In ancient Egyptian artwork, for example, the fight-hand is depicted as the dominant one in about 90 per cent of the examples. Fracture or wear patterns on tools also indicate that a majority of ancient people were fight - handed.
Cro-Magnon cave paintings some 27,000 years old commonly show outlines of human hands made by placing one hand against the cave wall and applying paint with the other. Children today make similar out lines of their hands with crayons on paper. With few exceptions, left hands of Cro-Manganese are displayed on cave walls, indicating thai the paintings were usually done by right-handers.
Anthropological evidence pushes the record of handedness nearly human ancestors back to at least 1.4 million years ago. One important line of evidence comes from flaking patterns of stone cores used in tool making: implements flaked with a clockwise motion (indicating a right- handed toolmaker) can be distinguished frp, those flakea wan a counter- clockwise rotation (indicating a left -handed toolmaker).
Even scratches found on fossil human teeth offer clues. Ancient humans are thought to have cut meat into strips by holding it between their teeth and slicing it with stone knives, as do the present -day Inuit. Occasionally the knives slip and leave scratches on the users' teeth. Scratches made with a left - to - right stroke direction (by right-handers) are more common than scratches in the opposite direction (made by left-handers).
Still other evidence comes from cranial morphology: scientists think that physical differences between the right and left sides of the interior of the skull indicate subtle physical differences between the two sides of the brain. The variation between the hemispheres corresponds to which side of the body is used to perform. specific activities. Such studies, as well as studies of tool use, indicate that right - or left – sided dominance is not exclusive to modem Homo sapiens. Populations of Neanderthals, such as Homo erects and Ho mo habilis, seem to have been predominantly right -handed, as we are.
What is the main idea of the passage？
A．Human ancestors became predominantly right- handed when they began to use tools.
B．It is difficult to interpret the significance of anthropological evidence concerning tool use,
C．Human and their ancestors have been predominantly right -handed for over a million years.
D．Human ancestors were more skilled at using both hands than modem humans.

Does money buy happiness？ It's sometimes said that scientists have found no relationship between money and happiness, but that's myth, says University of Illinois psychologist Ed Diener.
The connection is complex. In fact, very rich people rate substantially higher in satisfaction with life than very poor people do, even within wealthy nations, he says. "There is overwhelming evidence that money buys happiness," said economist Andrew Oswald of University of Warwick in England. The main debate, he said, is how strong the effect is.
Oswald recently reported a study of Britons who won between ＄ 2,000 and ＄ 250,000 in a lottery (彩票拍奖). As a group, they showed a boost in happiness averaging a bit more than one point on a 36-point scale when surveyed two years after their win, compared to their levels two years before they won.
Daniel Kahnman, a Nobel-Prize winner and Princeton economist, and colleagues, recently declared that the notion that making a lot of money will produce good overall mood is "mostly illusory". They noted that in one study, members of the high-income group were almost twice as likely to call themselves "very happy" as people from households with incomes below ＄ 20,000. But other studies, rather than asking for a summary estimate of happiness, follow people through the day and repeatedly record their feeling. These studies show less effect of income on happiness. Kahneman and colleagues said.
There is still another twist to the money-happiness story. Even though people who make＄150,000 are considerably happier than those who make ＄ 40,000, It's not clear why, says psychologist Richard E. Lucas of Michigan State University.
Researchers conclude that any effect of money on happiness is smaller than most daydreamers assume. "People exaggerate how much happiness is bought by an extra few thousand," Oswald said. "The quality of relationships has a far bigger effect than quite large rises in salary. It's much better advice, if you're looking for happiness in life, try to find the right husband or wife than to try to double your salary."
The main purpose of this passage is to discuss ______
A．the contributions of household incomes to happiness
B．the complex relationship between money and happiness
C．the positive relationship between money and happiness
D．the negative relations of money to happiness

第7题

Few people doubt the fundamental importance of mothers in child-rearing, but what do fathers do？ Much of what they contribute is simply the result of being a second adult in the home. Bringing up children is demanding, stressful and exhausting. Two adults can support and make up for each other's deficiencies and build on each other's strengths.
Fathers also bring an array of unique qualities. Some are familiar: protector and role model. Teenage boys without fathers are notoriously prone to trouble. The pathway to adulthood for daughters is somewhat easier, but they must still learn from their fathers, in ways they cannot from their mothers, how to relate to men. They learn from their fathers about heterosexual trust, intimacy and difference. They learn to appreciate their own femininity from the one male who is most special in their lives. Most important, through loving and being loved by their fathers, they learn that they are love-worthy.
Current research gives much deeper and more surprising insight into the father's role in child-rearing. One significantly overlooked dimension of fathering is play. From their children's birth through adolescence, fathers tend to emphasize play more than caretaking. The father's style. of play is likely to be both physically stimulating and exciting. With older children it involves more teamwork, requiring competitive testing of physical and mental skills. It frequently resembles a teaching relationship: come on, let me show you how. Mothers play more at the child's level. They seem willing to let the child directly play.
Kids, at least in the early years, seem to prefer to play with daddy. In one study .of 2.5-year-olds who were given a choice, more than two-thirds chose to play with their fathers.
The way fathers play has effects on everything from the management of emotions to intelligence and academic achievement.It is particularly important in promoting self-control. According to one expert, "children who roughhouse with their fathers quickly learn that biting, kicking and other forms of physical violence are not acceptable." They learn when to "shut it down."
At play and in other realms, fathers tend to stress competition, challenge, initiative, risktaking and independence.Mothers, as caretakers, stress emotional security and personal safety. On the playground fathers often try to get the children to swing ever higher, while mothers are cautious, worrying about an accident.
We know, too, that fathers' involvement seems to be linked to improved verbal and problem solving skills and higher academic achievement. Several studies found that along with paternal strictness, the amount of time fathers spent reading with them was a strong predictor of their daughters' verbal ability.
For sons the results have been equally striking. Studies uncovered a strong relationship between fathers' involvement and the mathematical abilities of their sons. Other studies found a relationship between paternal nurturing and boys' verbal intelligence.
The first paragraph points out that one of the advantages of a family with both parents is ______.
A．husband and wife can share housework
B．two adults are always better than one
C．the fundamental importance of mothers can be fully recognized
D．husband and wife can compensate for each other's shortcomings

根据下列文章，回答21～25题。 While still catching-up to men in some spheres of modern life
根据下列文章，回答21～25题。
While still catching-up to men in some spheres of modern life, women appear to be way ahead in at least one undesirable category. Women are particularly susceptible to developing depression and anxiety disorders in response to stress compared to men, according to Dr. Yehuda, chief psychiatrist at New York''s Veteran''s Administration Hospital.
Studies of both animals and humans have shown that sex hormones somehow affects the stress response, causing females under stress to produce more of the trigger chemicals than do males under the same conditions. In several of the studies, when stressed-out female rats had their ovaries （the female reproductive organs） removed, their chemical responses became equal to those of the males.
Adding to a woman''s increased dose of stress chemicals, are her increased opportunities for stress. It''s not necessarily that women don''t cope as well. It''s just that they have so much more to cope with, says Dr. Yehuda. Their capacity for tolerating stress may even be greater than men''s, she observes, It''s just that they''re dealing with so many more things that they become worn out from it more visibly and sooner.
Dr. Yehuda notes another difference between the sexes. I think that the kinds of things that women are exposed to tend to be in more of a chronic or repeated nature. Men go to war and are exposed to combat stress. Men are exposed to more acts of random physical violence. The kinds of interpersonal violence that women are exposed to tend to be in domestic situations, by, unfortunately, parents or other family numbers, and they tend not to be one-shot deals. The wear-and-tear that comes from these longer relationships can be quite devastating.
Adeline Alvarez married at 18 and gave birth to a son, but wad determined to finish college. I struggled a lot to get the college degree. I was living in so much frustration that that was my escape, to go to school, and get ahead and do better. Later her marriage ended and she became a single mother. It''s the hardest thing to take care of a teenager, have a job, pay the rent, pay the car payment, and pay the debt. I lived from paycheck to paycheck.
Not everyone experiences the kinds of severe chronic stresses Alvarez describes. But most women today are coping with a lot of obligations, with few breaks, and feeling the strain. Alvarez''s experience demonstrates the importance of finding ways to diffuse stress before it threatens your health and your ability to function.
第 21 题 Which of the following is true according to the first two paragraphs？
A．Women are biologically more vulnerable to stress.
B．Women are still suffering much stress caused by men.
C．Women are more experienced than men in coping with stress.
D．Men and women show different inclinations when faced with stress.

The teenage years should be the best years of your life!Young people often hear adults
The teenage years should be the best years of your life!
Young people often hear adults say this, but many teenagers disagree. They simply don’t feel like they’re in the midst of their best years. The pressures of school exams and concerns about relationships with family and friends create a great deal of stress for the average teenager. Many find ways to cope with the stress. But for a large number of teens, their problems seem impossible to deal with. When this happens, the young person may fall into depression.
In mainland China, a survey found that 16 percent of college students suffered from fear, anxiety, or depression. Increasing mental health problems have prompted the government to look for possible solutions.
This growing trend extends beyond Asia, too. Studies in the U.S. and the UK show that teenage depression is on the rise. A 2004 report stated that emotional problems among Britain’s youth have increased by 70 percent over the past 25 years.
Faced with these startling numbers, mental health professionals are hoping to raise awareness. Depression can range from mild unhappiness to thoughts of suicide. For this reason, adults should take the illness seriously. Parents can do this by learning about the causes and symptoms of teen depression.
Some factors that may lead to teenage depression are:
●Overwhelming expectations by parents and other adults
●Parental separation or divorce
●Death of a loved one
●Moving to a new location
●Physical illness
Most of the time when teens are depressed, there’something wrong in their lives, says UCLA psychology professor Constance Hammen. Kids often get depressed because bad things happen to them that they don’t have the coping skills to deal with.
If you are experiencing any symptoms of depression, you need to talk with someone. There’s no shame in being depressed. Most people suffer from it at one time or another.Unfortunately , feelings of depression may cause you to feel hopeless about your life and your future. But another person can help you put things in perspective.
(1)In paragraphs 3 and 4, a survey in mainland China and a 2004 report are mentioned to ______________.
A、indicate the contrast between mainland China and UK
B、show teenage depression is a serious problem in mainland China
C、show teenage depression is a growing problem in UK
D、indicate teenage depression is a growing problem in many countries.
(2)Why do kids often get depressed according to Constance Hammen？
A、Because bad things often happen to them.
B、Because there’s something wrong in their life.
C、Because they can’t deal with the problems.
D、Because they are weak.
(3)All of the following can fall into the category of depression EXCEPT __________.
A、stress
B、mild unhappiness
C、some mental or emotional problems
D、thoughts of suicide
(4)If you feel depressed, you should __________.
A、be ashamed
B、feel hopeless
C、talk to someone
D、enjoy your best years

词汇理解：Physical activity does the body good, and there's growing evidence that it helps the brain too.

Part III Reading Comprehension (40 minutes)2016年6月大学英语四级卷1真题及答案

Section A

Directions: In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.

Questions 26 to 35 are based on the passage you have just heard.

Physical activity does the body good, and there's growing evidence that it helps the brain too. Researchers in the Netherlands report that children who get more exercise, whether at school or on their own, 26 to have higher GPAs and better scores on standardized tests. In a 27 of 14 studies that looked at physical activity and academic 28 , investigators found that the more children moved, the better their grades were in school, 29 in the basic subjects of math, English and reading.

The data will certainly fuel the ongoing debate over whether physical education classes should be cut as schools struggle to 30 on smaller budgets. The arguments against physical education have included concerns that gym time may be taking away from study time. With standardized test scores in the U.S. 31 in recent years, some administrators believe students need to spend more time in the classroom instead of on the playground. But as these findings show, exercise and academics may not be 32 exclusive. Physical activity can improve blood 33 to the brain, fueling memory, attention and creativity, which are 34 to learning. And exercise releases hormones that can improve 35 and relieve stress, which can also help learning. So while it may seem as if kids are just exercising their bodies when they're running around, they may actually be exercising their brains as well.

A)attendance

B)consequently

C)current

D)depressing

E)dropping

F)essential

G)feasible

H)flow

I)mood

J)mutually

K)particularly

L)performance
