1、必修4 Unit 1 A STUDENT OF AFRICAN WILDLIFE It is 5:45 am and the sun is just rising over Gombe National Park in East Africa. Following Jane's way of studying chimps, our group are all going to visit them in the forest. Jane has studied these families of chimps for many years and helped peopl

2、e understand how much they behave like humans. Watching a family of chimps wake up is our first activity of the day. This means going back to the place where we left the family sleeping in a tree the night before. Everybody sits and waits in the shade of the trees while the family begins to wake up

3、and move off. Then we follow as they wander into the forest. Most of the time, chimps either feed or clean each other as a way of showing love in their family. Jane warns us that our group is going to be very tired and dirty by the afternoon and she is right. However, the evening makes it all worthw

4、hile. We watch the mother chimp and her babies play in the tree. Then we see them go to sleep together in their nest for the night. We realize that the bond between members of a chimp family is as strong as in a human family. Nobody before Jane fully understood chimp behaviour. She spent yea

5、rs observing and recording their daily activities. Since her childhood she had wanted to work with animals in their own environment. However, this was not easy. When she first arrived in Gombe in 1960, it was unusual for a woman to live in the forest. Only after her mother came to help her for the f

6、irst few months was she allowed to begin her project. Her work changed the way people think about chimps. For example, one important thing she discovered was that chimps hunt and eat meat. Until then everyone had thought chimps ate only fruit and nuts. She actually observed chimps as a group hunting

7、 a monkey and then eating it. She also discovered how chimps communicate with each other, and her study of their body language helped her work out their social system. For forty years Jane Goodall has been outspoken about making the rest of the world understand and respect the life of these a

8、nimals. She has argued that wild animals should be left in the wild and not used for entertainment or advertisements. She has helped to set up special places where they can live safely. She is leading a busy life but she says: "Once I stop, it all comes crowding in and I remember the chimps in labor

9、atories. It's terrible. It affects me when I watch the wild chimps. I say to myself, 'Aren't they lucky?" And then I think about small chimps in cages though they have done nothing wrong. Once you have seen that you can never forget ..." She has achieved everything she wanted to do: working

10、with animals in their own environment, gaining a doctor's degree and showing that women can live in the forest as men can. She inspires those who want to cheer the achievements of women. WHY NOT CARRY ON HER GOOD WORK? I enjoyed English, biology, and chemistry at school, but which one sh

11、ould I choose to study at university? I did not know the answer until one evening when I sat down at the computer to do some research on great women of China. By chance I came across an article about a doctor called Lin Qiaozhi, a specialist in women's diseases. She lived from 1901 to 1983.

12、It seemed that she had been very busy in her chosen career, travelling abroad to study as well as writing books and articles. One of them caught my eye. It was a small book explaining how to cut the death rate from having and caring for babies. She gave some simple rules to follow for keeping babie

13、s clean, healthy and free from sickness. Why did she write that? Who were the women that Lin Qiaozhi thought needed this advice? I looked carefully at the text and realized that it was intended for women in the countryside. Perhaps if they had an emergency they could not reach a doctor. Sud

14、denly it hit me how difficult it was for a woman to get medical training at that time. That was a generation when girls' education was always placed second to boys'. Was she so much cleverer than anyone else? Further reading made me realize that it was hard work and determination as well as her gent

15、le nature that got her into medical school. What made her succeed later on was the kindness and consideration she showed to all her patients. There was story after story of how Lin Qiaozhi, tired after a day's work, went late at night to deliver a baby for a poor family who could not pay her.

16、 By now I could not wait to find out more about her. I discovered that Lin Qiaozhi had devoted her whole life to her patients and had chosen not to have a family of her own. Instead she made sure that about 50,000 babies were safely delivered. By this time I was very excited. Why not study at med

17、ical college like Lin Qiaozhi and carry on her good work? It was still not too late for me to improve my studies, prepare for the university entrance examinations, and…. 必修4 Unit 2 A PIONEER FOR ALL PEOPLE Although he is one of China's most famous scientists, Yuan Longping co

18、nsiders himself a farmer, for he works the land to do his research. Indeed, his sunburnt face and arms and his slim, strong body are just like those of millions of Chinese farmers, for whom he has struggled for the past five decades. Dr Yuan Longping grows what is called super hybrid rice. In 1974,

19、he became the first agricultural pioneer in the world to grow rice that has a high output. This special strain of rice makes it possible to produce one-third more of the crop in the same fields. Now more than 60% of the rice produced in China each year is from this hybrid strain. Born into

20、a poor farmer's family in 1930, Dr Yuan graduated from Southwest Agricultural College in 1953. Since then, finding ways to grow more rice has been his life goal. As a young man, he saw the great need for increasing the rice output. At that time, hunger was a disturbing problem in many parts of the c

21、ountryside. Dr Yuan searched for a way to increase rice harvests without expanding the area of the fields. In 1950, Chinese farmers could produce only fifty million tons of rice. In a recent harvest, however, nearly two hundred million tons of rice was produced. These increased harvests mean that 22

22、% of the world's people are fed from just 7% of the farmland in China. Dr Yuan is now circulating his knowledge in India, Vietnam and many other less developed countries to increase their rice harvests. Thanks to his research, the UN has more tools in the battle to rid the world of hunger. Using his

23、 hybrid rice, farmers are producing harvests twice as large as before. Dr Yuan is quite satisfied with his life. However, he doesn't care about being famous. He feels it gives him less freedom to do his research. He would much rather keep time for his hobbles. He enjoys listening to violin mu

24、sic, playing mah-jong, swimming and reading. Spending money on himself or leading a comfortable life also means very little to him. Indeed, he believes that a person with too much money has more rather than fewer troubles. He therefore gives millions of yuan to equip others for their research in agr

25、iculture. Just dreaming for things, however, costs nothing. Long ago Dr yuan had a dream about rice plants as tall as sorghum. Each ear of rice was as big as an ear of corn and each grain of rice was as huge as a peanut. Dr Yuan awoke from his dream with the hope of producing a kind of rice

26、that could feed more people. Now, many years later, Dr Yuan has another dream: to export his rice so that it can be grown around the globe. One dream is not always enough, especially for a person who loves and cares for his people. CHEMICAL OR ORGANIC FARMING? Over the past half cen

27、tury, using chemical fertilizers has become very common in farming. Many farmers welcomed them as a great way to stop crop disease and increase production. Recently, however, scientists have been finding that long-term use of these fertilizers can cause damage to the land and, even more dangerous, t

28、o people's health. What are some of the problems caused by chemical fertilizers? First, they damage the land by killing the helpful bacteria and pests as well as the harmful ones. Chemicals also stay in the ground and underground water for a long time. This affects crops and, therefore, ani

29、mals and humans, since chemicals get inside the crops and cannot just be washed off. These chemicals in the food supply build up in people's bodies over time. Many of these chemicals can lead to cancer or other illnesses. In addition, fruit, vegetables and other food grown with chemical fertilizers

30、usually grow too fast to be full of much nutrition. They may look beautiful, but inside there is usually more water than vitamins and minerals. With these discoveries, some farmers and many customers are beginning to turn to organic farming. Organic farming is simply farming without using an

31、y chemicals. They focus on keeping their soil rich and free of disease. A healthy soil reduces disease and helps crops grow strong and healthy. Organic farmers, therefore, often prefer using natural waste from animals as fertilizer. They feel that this makes the soil in their fields richer in minera

32、ls and so more fertile. This also keeps the air, soil, water and crops free from chemicals. Organic farmers also use many other methods to keep the soil fertile. They often change the kind of crop in each field every few years, for example, growing corn or wheat and then the next year peas o

33、r soybeans. Crops such as peas or soybeans put important minerals back into the soil, making it ready for crops such as wheat or corn that need rich and fertile soil. Organic farmers also plant crops to use different levels of soil, for example, planting peanuts that use the ground's surface followe

34、d by vegetables that put down deep roots. Some organic farmers prefer planting grass between crops to prevent wind or water from carrying away the soil, and then leaving it in the ground to become a natural fertilizer for the next year's crop. These many different organic farming methods have the sa

35、me goal: to grow good food and avoid damaging the environment or people's health. 必修4 Unit 3 A MASTER OF NONVERBAL HUMOUR As Victor Hugo once said, "Laughter is the sun that drives winter from the human face", and up to now nobody has been able to do this better than Charlie

36、 Chaplin. He brightened the lives of Americans and British through two world wars and the hard years in between. He made people laugh at a time when they felt depressed, so they could feel more content with their lives. Not that Charlie's own life was easy! He was born in a poor family in 1889

37、. His parents were both poor music hall performers. You may find it astonishing that Charlie was taught to sing as soon as he could speak and dance as soon as he could walk. Such training was common in acting families at this time, especially when the family income was often uncertain. Unfortunately

38、 his father died, leaving the family even worse off, so Charlie spent his childhood looking after his sick mother and his brother. By his teens, Charlie had, through his humour, become one of the most popular child actors in England. He could mime and act the fool doing ordinary everyday tasks. No o

39、ne was ever bored watching him -his subtle acting made everything entertaining. As time went by, he began making films. He grew more and more popular as his charming character, the little tramp, became known throughout the world. The tramp, a poor, homeless man with a moustache, wore large tro

40、users, worn-out shoes and a small round black hat. He walked around stilly carrying a walking stick. This character was a social failure but was loved for his optimism and determination to overcome all difficulties. He was the underdog who was kind even when others were unkind to him. How did

41、the little tramp make a sad situation entertaining? Here is an example from one of his most famous films, The Gold Rush. It is the mid-nineteenth century and gold has just been discovered in California. Like so many others, the little tramp and his friend have rushed there in search of gold, but wit

42、hout success. Instead they are hiding in a small hut on the edge of a mountain during a snowstorm with nothing to eat. They are so hungry that they try boiling a pair of leather shoes for their dinner. Charlie first picks out the laces and eats them as if they were spaghetti. Then he cuts off the le

43、ather top of the shoe as if it were the finest steak. Finally he tries cutting and chewing the bottom of the shoe. He eats each mouthful with great enjoyment. The acting is so convincing that it makes you believe that it is one of the best meals he has ever tasted! Charlie Chaplin wrote, direc

44、ted and produced the films he starred in. In 1972 he was given a special Oscar for his outstanding work in films. He lived in England and the USA but spent his last years in Switzerland, where he was buried in 1977. He is loved and remembered as a great actor who could inspire people with great conf

45、idence. ENGLISH JOKES 1 There are thousands of jokes which use "play on words" to amuse us. One person asks a question which expects a particular reply. Instead, what he gets is another kind of answer which makes the situation funny. Now read some of these customer and wa

46、iter jokes. Can you match the joke with the explanation?

47、 1 C: What's that fly doing in my soup? W: Swimming, I think! 2 C: What's that? W: It's bean soup. C: I don't want to know what it's been. I want to know what it is now. 3 C: Waiter, will the pancakes be long? W: No, sir. Round. 2

48、 Some jokes are longer and tell a short, funny story. The following is one of those jokes about the famous detective Sherlock Holmes and his friend Doctor Watson. Read it and decide which of these two kinds of jokes you like better. Give your reasons. Sherlock Holmes and Doctor Wats

49、on went camping in a mountainous area. They were lying in the open air under the stars. Sherlock Holmes looked up at the stars and whispered, "Watson, when you look at that beautiful sky, what do you think of?" Watson replied, "I think of how short life is and how long the universe has lasted." "No,

50、 no, Watson!" Holmes said. "What do you really think of?." Watson tried again. "I think of how small I am and how vast the sky is." "Try again, Watson!" said Holmes. Watson tried a third time. "I think of how cold the universe is and how warm people can be in their beds." Holmes said, "Watson, you f

51、ool! You should be thinking that someone has stolen our tent!" 必修4 Unit 4 COMMUNICATION: NO PROBLEM? Yesterday, another student and I, representing our university's student association, went to the Capital International Airport to meet this year's international students. They

52、 were coming to study at Beijing University. We would take them first to their dormitories and then to the student canteen. After half an hour of waiting for their flight to arrive, I saw several young people enter the waiting area looking around curiously. I stood for a minute watching them and the

53、n went to greet them. The first person to arrive was Tony Garcia from Colombia, closely followed by Julia Smith from Britain. After I met them and then introduced them to each other, I was very surprised. Tony approached Julia, touched her shoulder and kissed her on the cheek! She stepped ba

54、ck appearing surprised and put up her hands, as if in defence. I guessed that there was probably a major misunderstanding. Then Akira Nagata from Japan came in smiling, together with George Cook from Canada. As they were introduced, George reached his hand out to the Japanese student. Just at that m

55、oment, however, Akira bowed so his nose touched George's moving hand. They both apologized - another cultural mistake! Ahmed Aziz, another international student, was from Jordan. When we met yesterday, he moved very close to me as I introduced myself. I moved back a bit, but he came closer t

56、o ask a question and then shook my hand. When Darlene Coulon from France came dashing through the door, she recognized Tony Garcia's smiling face. They shook hands and then kissed each other twice on each cheek, since that is the French custom when adults meet people they know. Ahmed Aziz., on the c

57、ontrary, simply nodded at the girls. Men from Middle Eastern and other Muslim countries will often stand quite close to other men to talk but will usually not touch women. As I get to know more international friends, I learn more about this cultural "body language". Not all cultures greet eac

58、h other the same way, nor are they comfortable in the same way with touching or distance between people. In the same way that people communicate with spoken language, they also express their feelings using unspoken "language" through physical distance, actions or posture. English people, for example

59、, do not usually stand very close to others or touch strangers as soon as they meet. However, people from places like Spain, Italy or South American countries approach others closely and are more likely to touch them. Most people around the world now greet each other by shaking hands, but some cultu

60、res use other greetings as well, such as the Japanese, who prefer to bow. These actions are not good or bad, but are simply ways in which cultures have developed. I have seen, however, that cultural customs for body language are very general - not all members of a culture behave in the same w

61、ay. In general, though, studying international customs can certainly help avoid difficulties in today's world of cultural crossroads! SHOWING OUR FEELINGS Body language is one of the most powerful means of communication, often even more powerful than spoken language.

62、People around the world show all kinds of feelings, wishes and attitudes that they might never speak aloud. It is possible to "read" others around us, even if they do not intend for us to catch their unspoken communication. Of course, body language can be misread, but many gestures and actions are u

63、niversal. The most universal facial expression is, of course, the smile – its function is to show happiness and put people at ease. It does not always mean that we are truly happy, however. Smiles around the world can be false, hiding other feelings like anger, fear or worry. There are unhap

64、py smiles, such as when someone "loses face" and smiles to hide it. However, the general purpose of smiling is to show good feelings. From the time we are babies, we show unhappiness or anger by frowning. In most places around the world, frowning and turning one's back to someone shows anger

65、. Making a fist and shaking it almost always means that someone is angry and threatening another person. There are many ways around the world to show agreement, but nodding the head up and down is used for agreement, almost worldwide. Most people also understand that shaking the head from si

66、de to side means disagreement or refusal. How about showing that I am bored? Looking away from people or yawning will, in most cases, make me appear to be uninterested. However, if I turn toward and look at someone or something, people from almost every culture will think that I am interested. If I roll my eyes and turn my head away, I most likely do not believe what I am hearing or do not like it. Being respectful to people is subjective, based on each culture, but in general it
