| Body and Food Your body, which has close relations with the food you eat, is the most important thing you own, so it needs proper treatment and proper nourishment (营养).The old saying "An apple a day keeps the doctor away"is not as silly as some people think. The body needs fruit and vegetables because they contain vitamin C. Many people take extra vitamins in pill form, believing that these will make them healthy.

| In a world with limited land, water and other natural resources (资源), the harm from the traditional business model is on the rise. Actually, the past decades has seen more and more forests disappearing and globe becoming increasingly warm. People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable (可持续的) ways. That means growth with low carbon or development of sustainable products. In other words, we should keep the earth healthy while using its supply of natural resources. Today, sustainable development is a proper trend in many countries. According to a recent study, the global market for low-carbon energy will become three times bigger over the next decades. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy revolution. It is now trying hard to make full use of wind and solar energy, and is spending a huge amount of money making electric cars and high-speed trains. In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil (棕榈油), which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown by more than 50%. Governments can fully develop the potential of these new markets. First, they can set high targets for reducing carbon emissions (排放) and targets for saving and reusing energy. Besides, stronger arrangement of public resources like forests can also help to speed up the development. Finally, governments can avoid the huge expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate the change from traditional model to a sustainable one. The major challenge of this century is to find ways to meet the needs of growing population within the limits if this single planet. That is no small task, but it offers abundant new chances for sustainable product industries. | |
| 1. The traditional business model is harmful because of all the following EXCEPT that ______. | |
| A. It makes the world warmer B. it consumes natural resources C. it brings severe damage to forests D. it makes growth hard to continue | |
| 2. What can we infer from Paragraph 2? | |
| A. China lacks wind and solar energy. B. China is the leader of the low-carbon market. C. High-speed trains are a low-carbon development. D. Palm oil is made at the cost of valuable forests. | |
| 3. To full develop the low-carbon markets, government can ______. | |
| A. cut public expenses B. forbid carbon emission C. develop public resources D. encourage energy conservation | |
| 4. We can learn from the last paragraph that businesses have many chances to ______. | |
| A. develop sustainable products B. explore new natural resources C. make full use of natural resources D. deal with the major challenge | |
| 5. What is the main purpose of the passage? | |
| A. To introduce a new business model. B. To compare two business models. C. To predict a change of the global market. D. To advocate sustainable development. | |

| Green-space facilities are contributing to an important extent to the quality of the urban environment. Fortunately it is no longer necessary that every lecture or every book about this subject has to start with the proof of this idea. At present it is generally accepted, although more as a self-evident statement than on the base of a closely-reasoned scientific proof. The recognition of the importance of green-spaces in the urban environment is a first step on the right way; this does not mean, however, that enough details are known about the functions of green spaces in towns and about the way in which the inhabitants are using these spaces. The theoretical separation of living, working, traffic and recreation which for many years has been used in town-and-country planning, has in my opinion resulted in disproportionate (不成比例的) attention for forms of recreation far from home, whereas there was relatively little attention for improvement of recreative possibilities in the direct neighborhood of the home. We have come to the conclusion that this is not right, because an important part of the time which we do not pass in sleeping or working, is used for activities at and around home. So it is obvious that recreation in the open air has to begin at the street door of the house. The urban environment has to offer as many recreation activities as possible, and the design of these has to be such that more obligatory (强制性的) activities can also have a recreative aspect. The very best standard of living is nothing if it is not possible to take a pleasant walk in the district, if the children cannot be allowed to play in the streets, because the risks of traffic are too great, if during shopping you can nowhere find a spot of enjoying for a moment the nice weather, in short, if you only feel yourself at home after the street door of your house is closed after you. | |
| 1. According to the author, the importance of green spaces in the urban environment _______. | |
| A. is still unknown B. is being closely studied C. is usually neglected D. has been fully recognized | |
| 2.The theoretical separation of living, working, traffic and recreation has led to _______. | |
| A. the disproportion of recreation facilities in the neighborhood B. all of the recreation facilities far from home C. relatively little attention for recreative possibilities D. the improvement of recreative possibilities in the neighborhood | |
| 3.The author suggests that the recreative possibilities of green spaces should be provided _______. | |
| A. in special areas B. in the suburbs C. in the neighbourhood of the house D. in gardens and parks | |
| 4. The author says "more obligatory activities can also have a recreative aspect" to _______. | |
| A. suggest that obligatory activities don"t need to serious B. show that recreation activities are very important C. show how recreation activities have spread wildly D. suggest how to offer recreation activities around home | |
| 5. Why would someone only feel himself at home according to the last paragraph? | |
| A. One lives the very best standard of living. B. There are too many distractions outside his home. C. There are few recreations around his house. D. One needs the street door of his house to be opened always. | |

| The common cold is the world"s most widespread illness, which is probably why there are more myths (神话,想象) about it than any of the other illnesses. The most widespread mistake of all is that colds are caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated Arctic regions explorers have reported being free from colds until coming into contact again with infected (感染的) people from the outside world by way of packages and mail dropped from airplanes.? At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be doused (浸入) with cold water, and then stood about dripping (滴干) wet in drafty (通风的) rooms. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.? If cold and wet have nothing to do with catching colds, why are they more frequent in the winter? In spite of the most painstaking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.? No one has yet found a cure for the cold. There are drugs and pain suppressors such as aspirin, but all they do is to relieve the symptoms.? | |
