Yet his job can sometimes be just as exciting and dangerous as being an explorer.Mike works for MSF, an organization also known as Doctors Without Borders (无国界医生). MSF sends trained doctors all over the world to help people

2、after a war or a disaster. Mike is a doctor from France who has travelled to many plates to organize programs that help people.At the moment, there are 27,000 trained medical staff taking part in MSF tasks. The organization received the Nobel Peace Prize. All kinds of doctors can volunteer for MSF.

3、They need to be prepared to go almost anywhere in the world and of course doctors with experience in tropical (热带) diseases are especially useful because most of MSFs work is in Africa. When doctors completed a few tasks, they might be sent on an emergency task following a disaster such as an earthq

4、uake.But why would a doctor leave a comfortable life and a good salary to join MSF? According to Mike, the experience you gain is a great help in your career. Besides, just like the explorers of the past, you need to keep an open mind and learn to mix well with the people you meet. Most importantly,

5、 at the end of each task, you have made a real difference to peoples lives.体裁：记叙文Who, What his job The review(评价） of his jobWhat What WhatwhereWhy: 记叙文注意抓住时间(when)、地点(where)、人物(who)、事件(what)、原因及结果(why)，尤其是发生的事件。例（二）People who live in the countryside generally live longer than those who live in the c

6、ity. A number of reasons may help explain this point.To start with, farmers are in close contact with nature. They breathe fresh air. They make friends with trees and stones, cows and dogs. They listen to the songs of birds. They fight with strong winds. This contact with nature is good for the heal

7、th of both body and spirit.Next, hard physical work keeps farmers fit and healthy. It is widely believed that farmers suffer from far less diseases than people in the city. There are many diseases that are common in the city, but not in the countryside. For example, near-sightedness is almost unknow

8、n to farmers. Besides, being free from urban pressure does good to the health of farmers.Moreover, because there are less cars, motorcars and other kinds of vehicles in the countryside, one can walk more freely without being afraid of accidents.

10、eir land from damage by farming and the forces of nature. One important form of soil conservation is the use of windbreaks (防风林).Windbreaks are barriers formed by trees and other plants with many leaves. Farmers plant them in lines around their fields. Windbreaks stop the wind from blowing soil away

11、. They also keep the wind from destroying or damaging crops. They are very important for growing grains, such as wheat.There have been studies done on windbreaks in parts of West Africa. It is found that grain harvests can be 20% higher in fields protected by windbreaks compared to fields without su

12、ch protection.However, windbreaks seem to work best when they allow a little wind to pass through. If the wall of trees and plants stops wind completely, then violent air movements will take place close to the ground. These movements will lift soil into the air where it will be blown away. For this

13、reason, a windbreak is best if it has only 60% to 80% of the trees and plants needed to form a solid line.An easy role to remember is that windbreaks can protect areas up to ten times the height of the tallest trees in the windbreaks. There should be at least two lines in each windbreak. One line sh

14、ould be large trees. The second line, right next to it, can be shorter trees and other plants with leaves. Locally grown trees and plants are best for windbreaks.体裁：说明文说明对象：Windbreak1 目的、用途 2 构成3 功能，作用（2个）4 注意事项练习实战练习（一）One hot night last August, I tried everything I could think ofa warm bottle, son

15、gs, etc. to make him fall into sleep, but he just couldnt do it. Since I believed that a long night was waiting for me ahead, I had no choice but to bring a TV into his room to kill off the hours until dawn. I was surprised that the moment I turned on the TV, the baby became quiet right away and fix

16、ed his little eyes brightly on the screen. Not willing to waste an opportunity for sleep, I then tiptoed(用脚失走）out of the room, leaving him to watch the boring TV programs.I heard no more of the babys crying that night and the next morning when I went into his room, I found him still watching TV by h

17、imself. I found there was a metaphor (暗喻) in my babys behavior for the new generation. When I gave my boy some books to go over, he only spit upon them; when I read to him, he did not feel comfortable. So is it in the schools with my students. I find that our students dont read and they look down up

18、on reading and make light of those of us who teach it. All they want to do is to watch TV. After this experience with the baby, however, I have drawn a conclusion: “Let them watch it!” If television is much more attractive to children than books, why should we fight against it? Let them watch what t

Maybe thats why there are 1.4 billion bicycles and only 400 million cars on roads worldwide today.Bikes can take you almost anywhere, and there is no oil cost! Get on a bicycl

20、e and ride around your neighbourhood. You may discover something new all around you. Stopping and getting off a bike is easier than stopping and getting out of your car. You can bike to work and benefit from the enjoyable exercise without polluting the environment. You dont even have to ride all the

21、 way.Folding bikes work well for people who take the train. Just fold the bike and take it with you. You can do the same on an airplane. A folding bike can be packed in a suitcase. You can also take a common bike with you when you fly. But be sure to look for information by getting on airline websit

23、ike bicycling has been shown to make people feel better, more relaxed and self-confident. Bicycling is healthier than driving.实战练习（三）Understanding body language is important to success, whether in the business world or in our personal lives. However, some of our ideas about body language are wrong,

24、according to modern communication research.There is a belief that people with shifty(变化的) eyes are probably lying. As Paul Ekman says, “When we asked people how they could tell if someone was lying, too much blinking(眨眼) and shifty eyes were the answers.” Ekman goes on to argue against such a wrong

25、belief. Although this kind of body language is probably an expression of nervousness, it is not always because the person is lying. Shyness can, for example, make people shift their eyes. To understand what someones behavior means, you have to watch them carefully.There is also a belief that when me

26、eting someone, the more eye contact, the better. As a result people would like to make initial (开始的) contact in formal situations, like a job interview, by staring fixedly at the other human. Yet Ekman points out that most of us are comfortable with eye contact lasting a few seconds，but any eye cont

27、act that is longer than that cm make us nervous.In short, you must carefully consider the speaker and the speaking environment. Experts suggest that unless you know about someones basic communication style, you will have little hope in understanding their true feelings through body language. In othe

28、r words, body language carries important but not always true messages. 实战练习（四）Linda Evans was my best friendlike the sister I never had. We did everything together: having piano lessons, going to movies, swimming, and horseback riding.When I was 13, my family moved away. Linda and I kept in touch th

29、rough letters, and we saw each other on special timelike my wedding and Lindas. Soon we were busy with children and moving to new homes, and we wrote less often. One day a card that I sent came back, stamped “Address Unknown.” I had no idea how to find Linda.Over the years, I missed Linda very much.

30、 I wanted to share happiness of my children and then grandchildren. And I needed to share my sadness when my brother and then mother died. There was an empty place in my heart that only a friend like Linda could fill.One day I was reading a newspaper when I noticed a photo of a young woman who looke

31、d very much like Linda and whose last name was Wagman Lindas married name. “There must be thousands of Wagmans,” I thought, but I still wrote to her.She called as soon as she got my letter. “Mrs. Tobin! she said excitedly, “Linda Evans Wagman is my mother.Minutes later I heard a voice that I knew ve
