Teens are more likely to behave badly if their parents expect them to，a new US study has found.
“Parents who believe they are simply being realistic might actually be having a bad effect on their children，” Christy Buchanan，a teacher at Wake Forest University and one of the authors of the study，said. “Bad expectations on the part of both parents and children predict more rebellious (叛逆的) behaviors later on.”
The finding came from a study of more than 250 sixth and seventhgraders and their mothers. They were examined at the start of the study and again one year later. If kids’ mothers expected them to take more risks and be more rebellious，higher chances of risky behavior were seen.This_was_also_true when kids had bad expectations of themselves.
“Sometimes parents expect more negative behavior from their children than they should based on the children’s history of behavior，” Buchanan said.Parents shouldn’t be naive (无知的) about the possibility of bad behavior，she said，but it’s also a mistake to think that children who are wellbehaved will naturally become rebellious at the age of 13.
“By thinking risktaking or rebelliousness is normal for teenagers and showing that to their children，parents might add to other messages from society that make teenagers feel that they are strange if they are not willing to take risks or break laws，” she said.“This can mean，for example，that when parents expect teens to drink before they turn 21 or to do other risky behaviors，kids are less likely to refuse to do so later in their lives.”
On the other hand，parents’ expectations that teens can exhibit good behaviors and refuse to behave badly or to take risks could help reduce the possibility of bad behavior，Buchanan said.“As a parent，you should put expectations on your children carefully.”The passage is centered around the topic of________.

As the pace of life continues to increase, we are fast losing the art of relaxation. Once you are in the habit of rushing through lift, being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.
Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing it is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stre
ss gets out of
control that it can lead to poor performance
and ill health.
The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make choice between "figh
t" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme, but however little the stress is, it involves the same response. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Such serious conditions as high blood pressure and heart disease have established links with stress. Since we cannot remove stress from our lives (it would be unwise to do so even if we could), we need to find ways to deal with it. People are finding less and less time for relaxing themselves because_____.
| A．they do not know how to enjoy themselves |
| B．they do not believe that relaxation is important for health |
| C．they are travelling fast all the time |
| D．they are becoming busier with their work |
According to
the writer, the most important character for a good manager is his ________.
| A．not fearing stress | B．knowing the art of relaxation |
| C．high sense of responsibility | D．h aving control over performance |
Which of the following statements is true?
| A．We can find some ways to avoid stress. |
| B．Stress is always harmful to people. |
| C．It is easy to change the habit of keeping oneself busy with work. |
| D．Different people can withstand different amounts of stress. |
In the last sentence of the passage, "do so " refers to ______.
| A．"expose ourselves to stress" |
| B．"find ways to deal with stress" |
| C．"remove stress from our lives" |
| D．"established links between diseases and stress" |
Nuclear radiation （核辐射）has a certain mystery, partly because it cannot be detected （探测）by human senses. It can’t be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can’t detect them or sense them without a radio receiver. Similarly, we can’t sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being at once by killing plenty of cells in important organs(器官). Even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and when they are killed at once. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in an unusual way. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the knowledge of the person at the time that damage has occurred. A person can be irradiated(放射治疗) and feel fine, then die of cancer five, ten, or twenty years later as a result. A child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents.According to the passage, the danger of nuclear power lies in .
| A．nuclear mystery | B．radiation detection |
| C．radiation level | D．nuclear radiation |
Radiation can lead to serious trouble even at the lowest level .
| A．when it kills a few cells |
| B．because the killed cells can’t be replaced |
| C．if it damages a few cells |
| D．unless the damaged cells can reproduce themselves |
What does the author want to tell us?
| A．Radiation can hurt us. | B．Radiation is a subject scientists work on. |
| C．Radiation is a mystery. | D．Radiation is the source of cancer. |
Most young people enjoy some form of physical activity. It may be walking, cycling, or swimming, or in winter, skating or skiing. It may be games of football, hockey, golf, or tennis. It may be mountaineering.
Those who have a passion for climbing high and difficult mountains are often looked upon with astonishment. Why are men and women willing to suffer cold and hardship, and to take risks on high mountains? This astonishment is caused probably by the difference between mountaineering and other forms of activity to which men give their relaxation.
Mountaineering is a sport and not a game. There are no man-made rules, as there are for such games as golf and football. There are, of course, rules of a different kind which it would be dangerous to ignore, but it is this freedom from man-made rules that makes mountaineering attractive to many people. Those who climb mountains are free to use their own methods.
If we compare mountaineering and other more familiar sports, we might think that one big difference is that mountaineering is not a “team game”. We should be mistaken in this. There are, it is true, no “matches” between “teams” of climbers, but when climbers are on a rock face linked by a rope on which their lives may depend, there is obviously teamwork.
The mountain climber knows that he may have to fight forces that are stronger and more powerful than man. He has to fight the forces of nature. His sport requires high mental and physical qualities.
A mountain climber continues to improve in skill year after year. A skier (滑雪者) is probably past his best by the age of thirty, and most international tennis champions are in their early twenties. But it is not unusual for a man of fifty or sixty to climb the highest mountains in Alps. They may take more time than younger men, but they probably climb with more skill and less waste of effort, and they certainly experience equal enjoyment. The main difference between a sport and a game lies in .
| A．activity | B．uniform | C．rules | D．skills |
Mountaineering can be called a team sport because .
| A．mountaineers depend on each other while climbing |
| B．teams compete against each other |
| C．it is an Olympic event |
| D．there are five climbers on each team |
Which of the following might be the best title?
| A．How to Climb High Mountains | B．Mountain Climbers |
| C．Challenging Sports Activities | D．Mountaineering |
A well-known manufacturer of weighing machines produced a new model.
The machine had a computer inside it, and this computer could do wonderful things: it could weigh people very accurately; it could tell them their weight in their own language; and it could tell them what they should eat to reduce their weight.
