Scientists believe that one of our most important means of knowing what is going on around us is the sense of sound. We are warned of danger by sounds. Sounds serve to please us in music. Sound has a waste product, too, in the form of noise. Noise has been called unwanted sound. Noise is growing and it may get much worse before it gets any better.
In order to know how noise affects people and animals, scientists have been studying for several years. They are surprised by what they have learned. Peace and quiet are becoming harder to find. Noise pollution is a threat that should be looked at carefully.
Sounds is measured in units called decibels (分贝). At a level of 140 decibels people feel pain in their ears.
Trucks , buses , motorcycles, airplanes, boats, factories---all these things make noise. They trouble not only our ears, but minds and bodies as well.
There is a saying that it is so noisy that you can’t hear yourself think. Doctors who study noise believe that we must sometimes hear ourselves think. If we don’t, we may have headaches, other aches and pains, or even worse mental problems.
Noise adds more tension (紧张) to a society that has already faced enough stress.
1.The sense of sound _________.
A. makes us feel excited

Rivers are one of our most important natural resources. Many of the world’s great cities are located on rivers, and almost every country has at least one river flowing through it that plays an important part in the lives of its people.
Since the beginning of history, people have used rivers for transportation. The longest one in the United States is the Mississippi. The lifeline of Egypt is the Nile. To the people of India , the Ganges is great, but it is also important for transportation; ships can travel along it for a thousand miles. Other great rivers are the Congo in Africa and the Mekong in southeast Asia, The greatest of all for navigation(航海), however, is the Amazon in Brail, It is so wide and so deep that large ships can go about two thousand miles upon it.
Besides transportation, rivers give food, water to drink, water for crops, and chances for fun and recreation for the people who live along their banks. In order to increase the supply of water for crops, engineers sometimes build a dam across a river and let a lake form behind the dam. Then people can use the water not only to irrigate their fields but also to make electricity for their homes and industries.
However, large cities and industries that are located upon rivers often make problems. As the cities grow in size and industries increase in number, the water in the rivers becomes polluted with chemicals and other materials. People are learning the importance, however, of doing more to keep their rivers clean if they want to enjoy the benefits of this natural resource.
1.The greatest river for navigation is .
A．the Amazon B．the Nile

People are overweight for many reasons, the most important one of which is that they eat the wrong foods, get the wrong types of calories per meal, and they also eat meals at the wrong time each day. Food is more powerful than any weight loss pill, because the food that you eat can either make you thin or fat. This is true because your body is like an engine, and it only needs certain foods at certain intervals(间隔) each day.
Low-calorie Diets Do Not Work
The reason people cannot lose weight by starving themselves is that their metabolism(新陈代谢) will detect any major drop in calories and it will then adjust itself by burning fewer calories each day. That is the reason why you can eat 1,000 calories per day and not lose any weight, while your friends can eat 2,500 calories per day and not gain any weight.
Low-fat Diets Do Not Work
Many people in today’s society are buying mostly low-fat or non-fat food at the grocery store. Everybody knows how much fat is inside the food they buy. However, people are getting fatter than ever before by doing this. They are not losing weight by changing to this low-fat lifestyle.
Losing weight has nothing to do with these things. One of the most important things you can do to control your weight is to eat the proper foods, such as fruit and vegetables, eat them at the right time, and exercise every day. If people make this a habit, they will lose weight.
1.What is the main reason why people are overweight?
A. They burn many calories every day.
B. They eat the wrong foods at the wrong time.
C. They eat food with lots of calories.
D. They don’t take weight loss pills.
2.The article is written in order to________.
A. tell readers not to buy low-fat or non-fat food.
B.tell readers about an important scientific discovery.
C.tell readers how to lose weight.
D. call on people to lose weight and stay healthy.
3.To realize the aim of your weight loss plan, you should_________.
a. do exercise every day b. eat meals at the right time
c. eat fruits and vegetables d. eat low-fat or sweet food
e. eat the proper foods at each meal
A. a, b, c, e B. a, b, d, e

All parents know that one of their most important tasks is to prepare their children for an independent life, but any parent can tell you that it’s hard to let go of your children. That balance between keeping your children safe and allowing them to learn from their own mistakes can be heartbreaking. Years of experience means that parents often do know best, but on the other hand the young, being less bound by tradition, are often more creative, more able to find new solutions to old problems. Revolutions are led by the young.
Good teachers make the growth of critical thinking (批判性思维) easier in their students, only to find that this lead to a questioning of the teachers’ basic beliefs. Schools encourage parents to become involved, but are often embarrassed when parents have doubts about some of the educational methods being used. Governments encourage unimportant groups to empower themselves in order to participate fully in the development process. And they are often surprised when the new leaders of these groups turn around and attack the policies or decisions of that same government. However, the rebellious (叛逆的) young and the newly unimportant groups are important in social development. They are not necessarily representatives of those they want to represent in their demands, but their voices must be heard.
Good parents know that just forbidding (禁止) particular behaviors does not prevent their children from finding ways to engage in these forbidden activities. Indeed, sometimes the forbidden fruit is more inviting, just because it is not accepted by authority. Parents must work with their children to educate them on the facts, know as much as possible about the lives of their children, provide a good example, encourage more wholesome activities but also support their children when they don’t follow what is expected of them. But the most important point is that they also need to learn how to let go.
1.By saying “Revolutions are led by the young.”, the author indicates that young people are more _______.
A．conventional B．realistic C．creative D．heartbreaking
2.From the second Paragraph we know ________.
A．teachers’ basic beliefs should be questioned by students
B．schools encourage parents to question their education methods
C．government is satisfied with the new leaders’ attack on the policies
D．the voice of the rebellious young should be heard by the government
3.In order to educate children well, parents should _______.
A．forbid particular behaviors in their daily life
B．know them well and set a good example to them
C．educate them with facts and expect much of them
D．know as much as possible about their children
4.From the passage we can learn that the author prefers _______.
A．free parenting B．traditional parenting
C．critical parenting D．smart parenting
5.What is the best title of the passage?
A．Letting Go – for Children’s Independent Life
B．Parents’ Task – in Children’s Development
C．Way of Growth – for the Young Groups
D．Teaching Methods – for Teachers and Schools

Researchers have found that most of our tiredness comes from our mental attitudes (心态). One of England’s doctors, J.A. Hadfield, says, “ 1. . In fact, tiredness of completely physical origin (缘由) is unusual.” So, remember -- the key to improved productivity is learning to relax. Here are some suggestions for you.
Relax form time to time
2. . It is said that if you want to master the art of relaxation, study the cat. Think about it. Have you ever seen a tired cat, or a cat with a nervous break-down? You will probably avoid this kind of feeling if you learn to relax as the cat does.
3.
Remember that tensions (紧张状态) on the body produce aching shoulders and nervous feelings. Variety and movement keep you physically and mentally alive. The most interesting task can get boring if done for long periods of time, and the most comfortable chair isn’t comfortable if the worker must sit in it for hours.
Think at the end of the day
4. . And if you are tired, is it because of the mental work you’ve done, or the way you have done it? Generally, if you feel extremely tired at the end of the day, it’s quite likely been an inefficient (效率低的) day.
5. Then you can work with a new attitude the next day.
A. Think of a cat
B. Work less hard
C. Work in a comfortable position
D. This will help you form the habit of relaxing.
E. Make notes of what changes you need to make.
F. Ask yourself how tired you are at the end of the day.
G. The greater part of tiredness comes from mental attitudes.
