Recently some American scientists have given a useful piece of advice to people in industrialized nations．They say people should eat more of the same kind of food eaten by humans living more than 10,000 years ago．   

       The scientists say that the human life has changed greatly．Our bodies have not been able to deal with these changes in lifestyle and this had led to new kinds of sicknesses．      So they are called "diseases of civilization"．Many cancers and diseases of the blood system are examples of such diseases.

       Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none．     However, a change in food is one of the main differences between life in ancient times and that of today.

       Stone Age people hunted wild animals for their meat, which had much less fat than domestic ones．They ate a lot of fresh wild vegetables and fruits．They did not have milk or any other dairy products, and they made very little use of grains．     We eat six times more salt than our ancestors．We eat more sugar．We eat twice as much fat but only one third as much protein and much less vitamin C.

           But scientists say that we would be much healthier if we eat much the same way the ancient people did, cutting the amount of fatty, salty and sweet food.

       A．Stone Age people lived a simple life.

       B．But today, we enjoy eating a lot of these.

       C．In that case, they would live much healthier.

       D．Ancient people also got lots of physical exercise.

       E．These new sicknesses were not known in ancient times.

       F．People today probably don't want to live like our ancestors.

       G．Modern people used to suffer from "diseases of civilization".

 

Humans are naturally drawn to other life forms and the worlds outside of our own. We take delight in the existence of creatures and even whole societies beyond our everyday lives.

This sense of wonder is universal. Look at the efforts that scientists have made to find out whether life of some kind exists on Mars, and the popularity of fantasy(幻想) literature or movies like The Lord of the Rings. This sense of wonder draws us to each other, to the world around us, and to the world of make-believe. But have we gone so far in creating worlds of fantasy that we are missing the pleasure of other worlds that already exist all around us?

Human beings, as biologists have suggested, possess an inborn desire to connect with and understand other life forms. However, people, especially in big cities, often lead rather isolated lives. In a study of British schoolchildren, it was found that children by age eight were much more familiar with characters from television shows and video games than with common wildlife. Without modern technology, a small pond could be an amazing world filled with strange and beautiful plants, insects, birds, and animals. When we lack meaningful interaction(交互) with the world around us, and sometimes even with our families and friends, we seek to understand and communicate with things that exist only in our imaginations or on a computer screen.

The world of make-believe is not necessarily bad. But when the world of fantasy becomes the only outlet(出路) for our sense of wonder, then we are really missing something. We are missing a connection with the living world. Other wonderful worlds exist all around us. But even more interesting is that if we look closely enough, we can see that these worlds, in a broad sense, are really part of our own.

1.The popularity of The Lord of the Rings proves       

A. the close connection between man and the fantasy world

B. the wonderful achievements of fantasy literature

C. the fine taste of moviegoers around the world

D. the general existence of the sense of curiosity

2.What can we infer from the underlined sentence in Paragraph 3?

A. People are far less familiar with the world of fantasy.

B. The world around us could serve as a source of wonder.

C. The world of fantasy can be mirrored by a small and lively pond.

D. Modern technology prevents us from developing our sense of wonder.

3.If our sense of wonder relies totally on the world of make-believe, we will       

A. fail to appreciate the joy in our lives

B. be confused by the world of make-believe

C. miss the chance to recognize the fantasy world

D. be trapped by other worlds existing all around us

4.What is the main purpose of the passage?

A. To show us the hidden beauty in our world.

B. To warn us not to get lost in the fantasy world.

C. To argue against the misuse of the sense of wonder.

D. To discuss the influence of the world of make-believe.

 

Gene technology to benefit people

Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.

The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span(寿命) can be prolonged.

Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial family being a good example, have hereditary(遗传的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist just need to find the wrong gene and correct it, and a healthy child will be born.

Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep, therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.    

What does "these two killers" in the second paragraph refer to? 

A. gene technology and another treatment of the two diseases.

B. The two murderers who killed the cloned baby

C. The two diseases of cancer and heart disease

D. Hereditary diseases and cancer

What's the main idea of the third paragraph?

A. How gene technology can be applied in the field of treating hereditary diseases.

B. Gene technology can be used to clone human babies.

C. Gene technology can help people to give birth of a baby.

D. Gene technology can help the English imperial family out

In what way gene technology can help to treat hereditary diseases?

A. Using gene technology, people with hereditary diseases can have more living days.

B. Using gene technology, scientist finds the wrong gene and corrects it.

C. Using gene technology, human babies can be cloned.

D. Doctors can cure cancer and heart disease with the help of gene technology.

What is the main purpose of writing this passage?

A. Expressing the writer's idea that gene technology will benefit people

B. Telling people the advantages of gene technology

C. Telling the readers that gene technology will not benefit people

D. Explaining that gene technology will also do harm to the humanity

We have all experienced days when everything goes wrong. A day may begin well enough, but suddenly everything seems to get out of control. It seems as if a single unimportant event may cause a number of things to happen. Let us suppose that you are preparing a meal and keeping an eye on the baby at the same time. The telephone rings and this means your troubles are beginning. While you are on the phone, the baby pulls the table-cloth off the table, destroying your prepared meal. You hang up hurriedly and attend to your baby. Meanwhile, the meal gets burnt. As if these were not enough to bring you to tears, your husband arrives unexpectedly bringing three guests to dinner.

Things can go wrong on-a number of people on the road. During the rush hour one evening, two cars hit each other and both drivers began to argue. The woman driver behind the two cars happened to be a learner. She suddenly went into a panic and stopped her car. This made the driver following her stop suddenly. His wife was sitting beside him holding a large cake. As she was thrown forward, the cake went right through the window and landed on the road’. Seeing a cake-flying through the air, a truck driver had to stop his truck all of a sudden. The truck was carrying empty beer bottles and hundreds of them slid off the back of the truck and fell onto the road. This led to yet another angry argument. Meanwhile, the traffic piled up behind. It took the police nearly an hour to get the traffic to move again. In the meanwhile, the truck driver had to sweep up hundreds of broken bottles. Only two dogs were enjoying themselves from the accident; for they were happily having what was left of the cake. It was just one of those days.
