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

Psychiatric tests show that a well-balanced person gets much angrier when offended than an
abnormal person does. At the New York State Psychiatric Institute, Dr. James Page and Professor of Psychology Carney Landis of Columbia University studied the reaction of 200 normal persons and 210 abnormal persons. They tested their reactions to annoying situations of every type and variety such as: being laughed at, being repeatedly disconnected on the telephone, accidentally hitting their thumb with a hammer, being worked on by a backseat driver, being told to "shut up" and mind their own business, discovering someone cheating in a friendly card game, etc. In almost every instance the anger reaction of the normal group was much more intense than that of the abnormal one.

"This," they reported, "is agreeing with other psychiatric findings. For one of the outstanding symptoms of mental unbalance is lack of emotion. So if you blow your top when you hit your head against a piece of furniture, or when your girlfriend goes out with another young man--don't worry about it. It is just a sign that you are normal."

The passage mainly deals with ______.

A．psychiatric studies of different types of anger reactions

B．the reactions of abnormal person to annoying situations

C．emotional reactions shown by normal and abnormal persons

D．the level of anger reactions shown by well-balanced persons

We use both words and gestures to express our feelings ,but the problem is that these word
s and gestures can be understood in different ways .

It is true that a smile means the same thing in any language . So does laughter or crying . There are also a number of striking similarities in the way different animals show the same feelings . Dogs , tigers and humans , for example , often show their teeth when they are angry . This is probably because they are born with those behavior. patterns .

Fear is another emotion that is shown in much the same way all over the world . In Chinese and English literature , a phrase like “he went pale and began to tremble”suggests that the man is either very afraid or deeply shocked . However , “he opened his eyes wide ” is used to suggest anger in Chinese whereas in English it means surprise . In Chinese surprise can be described in a phrase like “they stretched out their tongues ”. Sticking out your tongue in English is an insulting gesture or expresses strong dislike .

Even in the same culture , people differ in the ability to understand and express feelings Experiments in America have shown that women are usually better than men at recognizing fear ,anger love and happiness on people’s faces .

Does money buy happiness？ It's sometimes said that scientists have found no relationship b
etween 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

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.

Few people doubt the fundamental importance of mothers in child-rearing, but what do fathe
rs 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
