Unit 1



Women of achievement


Reading



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 people 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 beings to


wake up 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 worthwhile.



We watch the mother chimp and her babies


play in the tree.



Them 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 long as in a human family.





Nobody before Jane fully understood chimp behaviour.



She spent years 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 first 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 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.


Four forty years Jane Goodall has been outspoken about making the rest of the world


understand and respect the life of these animals.



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 li


ve safely.



She is leading a busy life but she says: “


Once I


stop, it all comes crowding in and I remember the chimps in laboratories.



It’s terrible.



It


affects me when I watch the wild chimps.



I say to myself, ‘Aren’t they luck?’



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 with animals in their own


environment, gaining a doctor’s degree and showing that women can l


ive in the forest as men


can.



She inspires those who want to cheer the achievement of women.





Using language



WHY NOT CARRY ON HER GOOD WORD?



I enjoyed English, biology, and chemistry at school, but which one should 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.



It


seemed that she had been very busy in


her chosen career, traveling abroad to study as well as writing books and articles.



One of


them caught my eye.



I 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 babies 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.


Suddenly it hit me how difficult it was for a woman to get medical training at that time.



That was a generation when girl’s 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 gentle 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.


By now I could not wait to find out more about her.



I discovered that Lin Qiaozhi had


devoted her whold 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 medical 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…




Unit 2



Working the land


A PILNEER FOR ALL PEOPLE


Although he is one of China’s most famous scientists, Yuan Longping considers h


imself 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, he became the first agricultural pioneer in the world to grow rich 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 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 countryside.



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% fo 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 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 hobbies.



He enjoys listening to violin music, 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 agriculture.




Just dreaming for things, however, costs nothing.



Long ago Dr Yuan had a dream about


rice plants as tall as a peanut.



Dr Yuan awoke from his dream with the hope of producing a


kind of rice 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 century, 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, to 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 ling time.



This affects crops and, therefore,


animals 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 t


ime.



Many of these


chemicals can lead to cancer or other illnesses.



In addition, fruit, vegetables and other food


grown with chemical fertilizers 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 any 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 minerals and


so more fertile.



This also keeps the air, 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 or 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 followed 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 same goal: to grown


good food and avoid damaging the environment or people’s health.





Unit 3



A state of English humour


Reading


A MSTER 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 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.



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, 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 English.



He could


mime and act the fool doing ordinary everyday tasks.



No one 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 trousers, worn- out shoes and a small round black


hat.



He walked around stiffly 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 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 without 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 leather top of the shoe as if it were


the finest steak.



Finally he tries cutting and chewing the bottom of the shoe. I 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, directed and produced the films he starred in.



In 1972 he was


given a special Oscar for his outstanding work in films.



He lived in English 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 confidence.





Using language


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 waiter jokes.



Can


you match the joke with the explanation?


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 d


on’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.



Explanation


A



The first person is asking for information about time.



The second person treats it as a


question about shape.
