Recently some American scientists have given a useful piece of advice to people in industrialized countries. They say people should eat more of the same kind of food eaten by humans living more than 10,000 years ago. 1
The scientists say that human life has changed greatly. Our bodies have not been able to deal with these changes in lifestyle and this has led to new kinds of sicknesses. 2 They are called “diseases of civilization”. Many cancers and diseases of the blood system arc examples of such diseases.
The scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none. 3 However, a change in food is one of the main differences between life in ancient times and that today.
Stone Age people hunted wild animals for their meat, which had much less fat than domestic(驯养的)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. 4 We eat six times more salt than our ancestors and we eat more sugar as well. We eat twice as much fat but only one third as much protein (蛋白质)and much less vitamin C.
5 But the scientists say that we would be much healthier if we eat much the same way the ancient people did, cutting the amount of fat, salty and sweet food.
A. Stone Age people lived a simple life without any meat.
B. But today, we enjoy eating a lot of these.
C. In that case, they would live a much healthier life.
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”.

In 1990 a report was published about what the earth might be like 20 years from then on. 71 According to the report,the picture of the earth in the year 2010 is not a pleasant one. 72 The population could be as large as 6300 million,almost 2150 million more than in 1985.More people would move into cities ,especially cities in developing countries.Cities like Cairo and Jakarta probably would each have 15 million by then.
73 Farmers will grow 90% more food than they did in 1985,but most of the increase would be in countries that already produce enough food for their people. 74 Poor farming ways are destroying large areas of crop land,changing farms into deserts.More farmland is lost as cities become larger and more houses are built.Air pollution will get worse as industrial countries burn more coal and oil.Many of the world's forests could disappear as more and more trees are cut down.Energy will continue to be a serious problem. 75 They only workde out the situation that exists today.By changing the situation,by settling the problems,the picture can be changed.There is still time for the nations of the world to work out a plan of action.But they warned that waiting too long to make de cisions would greatly reduce the chances of success.
