必修1英语Unit1课时跟踪练和高考满分作文：大树的求学之旅（46）课时跟踪练(一) Warm up & Lesson 1 Pre reading.阅读理解AMost of us lead unhealthy lives; we spend far too much sitting down. If in addition we are careless about our diets, our bodies soon become loose and fatty and our systems slow moving.There are some aspects (方面) of our unhealthy lives that we cannot avoid. I am thinking of such features of modern city life as pollution, noise, rushed meals and stress. But keeping fit is a way to reduce the effects of these evils. The usual suggestion to a person who is looking for a way to keep fit is to take up some sport or other. While it is true that every weekend you will find people playing football and hockey in the local park, they are outnumbered a hundred to one by the people who are simply watching them.For those who do not particularly enjoy competitive sports and it is especially difficult to do so if you are not good at them there are such separate activities as cycling, walking, jogging and swimming. What often happens though is that you do them in such a leisurely way, so slowly, that it is doubtful if you are doing yourself much good, except for the fact that you have at least managed to get up out of your armchair.Even after you have found a way for keeping in shape，through sport or gymnastics, you are still only half way to good health, because, according to the experts, you must also master the art of complete mental and physical relaxation (放松)It has to do with deep breathing, emptying your mind of all thoughts, meditation, and so on. Yoga, as practiced in the West, is the most widely known and popular of the systems for achieving the necessary state of relaxation. It seems ironical(讽刺性的), though, that as our lives have improved in a material sense we have found it increasingly necessary to go back to forms of activity physical effort on the one hand and relaxation on the other which were the natural way of life of our forefathers.语篇解读：健康的生活不仅包括适当的生理锻炼，还包括心理保健。1Pollution, noise and stress are examples of_.Acauses of unfitnessBbad features of living in townsCthe things we can completely do away withDunavoidable things in a town解析：选B细节理解题。根据第一段中的“There are some aspects (方面) of our unhealthy lives that we cannot avoid.

Since then, it has become a familiar term for a person who spends a lot of time sitting, and little time exercising. Although there does not seem to be any particular reason why the term “couch potato” is used rather than “couch tomato”， a person may become a “couch potato” because living this way is said to make you round like a potato. The term is also said to have something to do with the connection of potatoes with highcalorie (卡路里) food like potato chips.People now would say “couch potato” whenever they talk about overweight and obesity (肥胖). Indeed, “couch potatoes” are believed to risk heart disease, which can be avoided by regular exercise.It is true that technology and modern life in general make us sick, fat, lazy and physically/mentally soft. The more time people spend using technology, particularly televisions and computers, the less time they will spend being physically active.“Couch potato” kids are a particular concern. Media reports repeatedly claim that children today are fatter than their elder generations, but less athletically skilled, less interested in physical activity and more addicted (上瘾的) to “junk food” and technology such as televisions and computers. The message is clear：todays children are fat because they are lazy and eat too much.Moreover, because technology is becoming more sophisticated (复杂的), children are less able to resist (抵抗，忍得住) technologys attraction, and are more likely to spend more time using technology, less time doing physical activity and, therefore, more likely to be fat.语篇解读
