第1题

Recently some American scientists have given a useful sincere piece of advice to peopl

e in industrialized nations that they would be much healthier if they ate more of the same kind of food eaten by humans living more than 10,000 years ago.

The scientists say that the human body has changed very little since human first appeared on the earth, but the way we live has changed greatly.Our body has not been able to deal with these changes in life style. (方式) and this has led to new kinds of sicknesses.These new sicknesses were not known in ancient times (古代).So they are called “diseases of civilization”.Many cancers and diseases of the blood system (系统),including heart attacks and stroke (中风) are examples of such diseases.

Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol (酒精) or tobacco (烟草),probably none.Ancient people also got a great deal of physical exercise, but 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 or tame ones (家畜).They also 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.But today, we eat a large amount of these.We eat six times more salt than our remote ancestors.We eat more sugar.We eat twice as much fat but only one third as much protein (蛋白质) and much less vitamin.(维生素) C.

People today probably do not want to live the way people thousands of years ago did, but scientists say that we would be much healthier if we ate much the same way our remote ancestors did ,cutting the amount of fatty, salty and sweet food.

第5题

Mobile phones are the items that a lot of people are having today. However，do we really

need to have a mobile phone by our side？

We could start with the advantages of mobile phones. There are many things that we could do with mobile phones. With the advancement of technology，more and more features are being added to the mobile phones which make them more useful. In addition to making calls，mobile phones also support a wide variety of other services such as text messaging，email，Internet access，business applications，gaming and photography. We can bring them everywhere，and can be reached by others anytime. They make the world smaller，bringing people together no matter where they are.

But we could have some risks when using our mobile phones. We may have accidents when we use them while driving. Some studies show that mobile phones can do harm to our bodies;and materials in mobile phones could damage our environment.

Since there are so many risks，why do we still have mobile phones？This is because these risks or disadvantages can be overcome. For example，while we are driving we can easily pull up our car if we really need to use the phone. Mobile phone manufacturers are reducing the radiation of mobile phones to avoid health risks.

Though there are both pros and cons of using mobile phones，we could easily see that there are more advantages than disadvantages. Moreover，mobile phones are becoming cheaper，which might be another reason why mobile phones are increasingly used today.

B. Camera.

C. GPS.

2. What risks might mobile phones cause？

A. Traffic accidents and health problems.

3. What are mobile phone manufacturers doing to prevent mobile phone users from health risks？

A. They are reducing the radiation of mobile phones.

B. They are trying to persuade people to use mobile phones less.

C. They are developing new models of mobile phones.

4. Why do people still use mobile phones despite their disadvantages？

A. Because people don’t believe that mobile phones have any disadvantages.

B. Because the disadvantages of mobile phones can be avoided.

C. Because people cannot live without mobile phones.

5. According to the last paragraph，why are mobile phones increasingly being used today？

A. They are safer.
