Scientists are closely concerned with the structure of buildings and with the quality of building materials． The World health Organization （WHO) observes that the introduction of air conditioning and energy conservation （保护) measures have been accompanied by growing problems of indoor air quality． Some pollutants arise from insulation （隔音) products, some from moving cars, and others from modern housing materials． As many Europeans spend up to 90% of their lives in buildings, the health effects of the indoor climate are very important．
Some construction materials, including fiberboard, insulation foams and certain glues for man-made wood floor boards, for example, give out organic products such as formaldehyde （甲醛)． Heat and humidity increase the release of formaldehyde and the gas seriously harms the eyes． Paint, lacquer, etc． can also release dangerous gas into indoor air．
Construction materials can cause serious damage, especially when they contain asbestos（石棉）． Asbestos is naturally present in rock formations worldwide． It belongs to a family of mineral substances made up of solid, non-combustible（非易燃品） fiber． These properties make asbestos a highly sought-after construction material． As early as 1931, however, public health officers in t
he United Kingdom revealed the connection between breathing in asbestos dust and such diseases as lung cancer．
The land on which a building is sited may also contribute to pollution． Some kinds of granite or similar rocks contain traces of radium． As it breaks down, this naturally radioactive element produces some kind of radioactive gas that goes through tiny cracks in walls, floors and building materials, and makes its way into the building and the rooms． The better the homes are insulated, the more is the dangerous gas in indoor air． The main effect of this dangerous gas on health is to increase the risk of lung cancer．What is the main idea of the passage?
| A．Some building materials pollute indoor air． |
| B．Some factors cause indoor air pollution． |
| C．Asbestos can cause lung cancer． |
| D．The land on which houses are built contributes to indoor pollution． |
Why are Europeans particularly concerned with building materials?
| A．Lots of building materials there are radioactive． |
| B．They stay home up to 90% of their lives． |
| C．They have a high rate of lung cancer． |
| D．They spend most of their time indoors． |
Why is asbestos a sought-after building material?
| A．It is a kind of insulation foam． |
| B．Asbestos will not give out dangerous gas． |
| C．This material is not easy to catch fire． |
| D．It is rarely present in rock formations． |
Why should we be careful about the land on which a building is to be sited?
| A．To determine whether the land is firm enough for a building to be sited on． |
| B．To make sure that the land contains no radioactive material． |
| C．To make certain that the land releases no formaldehyde or other gases． |
| D．To check whether it contains any combustible materials． |
Thirty years ago not many people would have dreamed of doing the repairs and decorations in their own homes. In those days labor was fairly cheap and most people would have thought it worthwhile to employ a professional painter and decorator, unless of course they were either very hand up or were in the trade themselves. Today, however, it is quite a different story. Men and women in all walks of life turn their hands to all sorts of jobs round the house including painting, papering, putting up shelves and wall units, and tiling walls and floors. Some people with no professional training of any kind have even successfully built their own houses. These jobs have been made easier today by the introduction of prepared materials, which require the minimum amount of skill to use. In every high street throughout Britain nowadays there is at least one “Do-it-Yourself” shop containing a vast range of timber, tiles, paints, wallpapers and floor coverings besides tools of every description including power drills and many accessories. “Do-it-Yourself” is a booming business; all these shops do a roaring trade and look like continuing to do so. Probably the main reason for the craze is the high cost of present-day labor and the shortage of building firms willing to do small jobs. Why did people employ professional workers to decorate homes thirty years ago?
| A．Because they could not do it themselves. |
| B．Because professional workers were very cheap. |
| C．Because they had no time. |
| D．Because professional workers could do much better. |
Thirty years later what changes took place?
| A．People could do everything themselves. |
| B．Few people chose to be a professional worker |
| C．People with no professional training successfully built their own houses. |
| D．New expensive materials required no skills at all. |
What caused the DIY craze?
| A．Young people liked to follow the fashion. |
| B．“Do-it-Yourself” is a booming business. |
| C．There were fewer building companies. |
| D．High cost of professional workers. |
What is the speaker telling us?
| A．How DIY comes into being. |
| B．Changes in building. |
| C．Changes in housing. |
| D．Great changes in these thirty years. |
Internet dating has become one of the biggest and most successful business ventures on the Internet. Basically, Internet dating is a way to meet people for either friendship or dating without actually having to meet them in person first.
The first thing to do if you decide to try Internet dating is to build your profile(简介) which can include your hobbies, hopes for the future, and so on. A photograph is optional, but many sites claim that a photograph increase the number of people who look at your profile. Many Internet dating sites will charge a one-time registration(注册) fee to use their services.
Internet dating makes it possible to meet people from all over the world. You can even narrow the search down to your area by zip code. Another advantage is that you can communicate by email before you meet in person. Thousands of people have met, fallen in love, and married through Internet dating. It is an excellent way for shy people to meet. It is also a way for people with busy lives to connect with others, and an easy way to meet people who share your interests.
Just as in conventional(传统的) dating and love, there are some pitfalls to be aware of in Internet dating. The person you have been talking to on the net may not be who they say they are.

Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food, get enough sleep, and exercise regularly.
Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”. Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白质), like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (维他命) and minerals. However, don't overeat. It is not helpful to be overweight.
Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality (人的个性).Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.
Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.

From the beginning of human history, wild animals provided food, clothing and sometimes medicine. We may not depend as much on wild animals now. But we hear about them every day. Americans use the names of animals in many ways. Automobile manufacturers(制造商) and gasoline companies especially like to use big cats to sell their products. They like lions, tigers and wildcats. When Americans say wildcat, they usually mean a lynx, an ocelot or a bobcat. All these cats attack quickly and fiercely. So wildcats represent something fast and fierce.
An early American use of the word wildcat was quite different. It was used to describe members of Congress(国会) who declared war on Britain in 1812. A magazine of that year said the wildcat congressmen went home. It said they were unable to face the responsibility of having involved their country in an unnecessary war.
Wildcat also has been used as a name for money in the 1800s. At that time, some states permitted banks to make their own money. One bank in the state of Michigan offered paper money with a picture of a wildcat on it. Some banks, however, did not have enough gold to support all the paper money they offered. So the money had little or no value. It was called a wildcat bill or a wildcat bank note. The banks who offered this money were called wildcat banks. A newspaper of the time said those were the days of wildcat money. It said a man might be rich in the morning and poor by night.
Wildcat then was also used for an oil well or gold mine that had almost no oil or gold in it. Dishonest developers would buy such property. Then they would sell it and leave town with the money. The buyers were left with worthless holes in the ground. Today, wildcat oil wells are in areas that are not known to have oil. What is the main idea of the passage?
| A．Wildcats and their stories. |
| B．Wildcats and their characters |
| C．Varieties of animal species. |
| D．Relationship between animal and humans. |
From the passage we can know that______.
| A．wildcats represent the state of Michigan |
| B．the use of wildcat was not always the same |
| C．wildcats are the best friend of human beings |
| D．honest developers never buy wildcat oil wells |
