The perfect copy
Scientists have announced that they have cloned the first human embryo. This has caused much debate round the world. On the one hand, some scientists point out that if you clone an embryo, you can produce(value) human tissues—such as bone or lung tissue—that could be used to save human lives. On the other hand, many people, (include) some scientists, disagree and are afraid that, if mankind toys with nature in this way, we may be on our way to( produce) a real-life Frankenstein’s monster.
Cloning is producing an exact copy of a plant or an animal( use) its cells. The first mammal to be cloned( successful) from an adult cell was Dolly the sheep. She was born in 1996 and died in early 2003, a much younger age than normal. When she was born, many people were (worry) that cloning would lead to more (disease) in the animal world. However, in general the scientists were (praise) for their wonderful scientific advance.
Ian Wilmut, the Scottish scientist who created Dolly, is shocked that some scientists are now considering(clone) human beings. Although he researches cloning, his( intend) has never been to create copies of human. Instead, he thinks research (effort) should concentrate creating new tissues and organs that can be used (cure) diseases like cancer. However, some people believe that cloning human embryos with the intention of destroying them shows no respect for human life.
Even though human cloning is causing a lot of (anxious), it is good news for Faye Wilson, a 41-year-old saleswoman cannot have a bab y. ‘I am anxious to have a child of my own,’ she says. ‘I don’t want to adopt someone else’s child—If I had the chance, I would have a cloned baby right now.
While cloning human embryos is not legal in many countries, some scientists are already pushing ahead with research in order to produce a cloned human baby. SeverinoAntinori, an Italian physician, has declared that he wants to be the first to clone a human being.In China, scientists have focused their efforts on cloning animals, as well as cloned tissues to be used in medical treatment. China has succeeded producing clones of cows and goats, and continues to research ways in which cloning can benefit mankind.
(Letter 1) Dear Editor
I believe that human cloning is wrong. If we toy with nature , we will have to deal with the consequences. Who knows what could happen? Human life would just become a crop to be harvested or a product for sale.
The human race is using up the Earth’s natural wealth. We should be having fewer babies in order to reduce the Earth’s population, not cloning more.
I feel sorry for the lady who cannot have a baby, but I would like to point out that there are many children in the world with no parents who would be delighted to have a mother.

(Letter 2) Dear Editor
I would like to comment on y our article, ‘The perfect copy’. I think the scientific advances mentioned in your article are fantastic! I am in complete agreement with human cloning. After all, scientists have been challenging moral ideas for centuries. Why should we stop them now?
On a personal note, cloning would totally transform my life. Seven years ago, my 10-year-old daughter died of heart failure. She was beautiful, cheerful and bright. I miss her every single day. If I had the chance, I would clone her immediately so I that I could be with her again.

39. M5U3. Project (1)— Man and Nature
For a long time, our environment has been damaged because humans have been careless. People have harmed nature through agriculture, fishing, hunting and tourism. We further damage the Earth by building new channels in the sea and factories on the land, and by creating pollution with chemical waste. We will some day destroy the planet we live on if we continue in this way.
However, if we focus only on conservation, then people may suffer. Not everything that is best for nature is good for people. Would anyone say that development should be stopped in favor of nature.From the point of view of some people, we are only doing what humans have always done, using nature to meet our own needs.Other people argue that such thinking may cause a catastrophe, unless we start to look around and understand how a clean environment benefits us all.
改错，10个错误点
After decade of destroying nature and using up natural resources, many developed nations are now concerned in saving nature rather than developing or destroy it. However, many poorer nations must focus on meeting the everyday needs of our people. In doing so, they are using up natural resources at a fast pace. They have not yet seen the effects of the careless use of the environment like many wealthy nations have. Often they do not realize that the choices they make is bad for the environment. Should they be blamed for destroying hundred of thousands of acres of rainforest if it means a better income for their people? The developed and developing countries of the world need to work together to make sure that people enjoy healthily and happy lives, without the environment around them suffering.
It should not be question of humans winning and nature losing. Humans can only really win by protecting nature. After all, food has to be produced in a healthy, natural system, and we all need clean air to breathe and pure water drink. It is mankind’s responsibility to find an swers that are good at everyone, and everything.
40. M5U3. Project (2)—
GM food: hope or danger?
1 With this progress doors have been opened up to technologies that never existed before. While many people are excited about these new technologies, these same technologies frighten others. Nowhere is this truer than with genetically modified (GM) food.
2 . First, new material can be inserted into its DNA to give the plant or animal qualities which it would never have in nature. Second, material can be taken from the DNA of a plant or an animal in order to remove qualities which are not desired.
One aim of GM research is to produce food which will make us healthier.
3 . Supporters of GM food argue that GM plants are healthier and have larger harvests. While there has been research in GM animals such as pigs, no GM meat is being sold at present.
4 . No one really knows whether it is safe for animals or humans to eat. Scientists admit that more tests should be done on GM food. Research has been limited to increasing production profits, rather than making sure that GM foods are safe. GM food could therefore be dangerous to eat.
5 Since GM crops are planted outside, they are part of the food chain—insects and other animals eat them or use their products, and these insects and animals will be eaten by yet other animals. No one knows what effects the GM material might have on the food chain.
Since no one really knows whether GM food is safe, many countries have hesitated to give permission for the production of GM foods, as they would rather be cautious with this new technology.
A.So far, this technology has been used to produce plants which are better able to defend themselves against pests and disease.
B.There are two ways in which a plant or an animal can be genetically modified.
C. There is also a question as to whether GM plants are safe for the environment.
D. Many questions have been raised about GM food.
E. In recent years, there has been great progress in the study of genetics.
F. Have you ever heard genetically modified food before?
G. Someone may like GM food.。
