10.Recently some American scientists have given a useful piece of advice to people in industrialized(工业化) nations.They say people should eat more of the same kind of food eaten by humans living more than 10,000years ago.(66)C
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.(67)E So they are called"diseases of civilization(文明)".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.(68)BHowever,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(家养的) 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.(69)D 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.
(70)FBut 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(那样的话),they would live much healthier.
D.Ancient people also got lots of physical exercise.
E.These new sicknesses were not known in ancient times.

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

解答 66.C.推理判断题.根据前文They say people should eat more of the same kind of food eaten by humans living more than 10,000years ago人们应该吃1万年前人们吃的东西,在那种情况下,人们将活得更为健康;故选C.
