题目内容
14.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 10,000years ago.(16)EThe 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.(17)CSo 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.(18)D 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.(19)F 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.
(20)B 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.Modern people used to suffer from"diseases of civilization".
B.People today probably don't want to live like our ancestors.
C.These new sicknesses were not known in ancient times.
D.Ancient people also got lots of physical exercise.
E.In that case,they would live much healthier.
F.But today,we enjoy eating a lot of these.
G.Stone Age people lived a simple life.
分析 最近,美国科学家给工业社会的人提出一些建议,他们应该有类似于古代人一样的生活方式.
解答 ECDFB
16.E 上下文理解.根据前句They say people should eat more of the same kind of food eaten by humans living more than 10,000years ago,可知人们应该吃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.故答案为E.
17.C 上下文理解.根据前面提及的this had led to new kinds of sicknesses.以及后面的they are called"diseases of civilization".可知这会导致很多新疾病产生,并且被叫做文明病,但在古代这些病却没有,故答案为C.
18.D 上下文理解.根据前文enjoyed very little alcohol or tobacco,probably none.可知古代人不抽烟喝酒,接下来应该说古代人还经常锻炼.故答案为D.
19.F 上下文理解.根据前面的几句Stone Age people hunted wild animals for their meat,which had much less fat than domestic ones讲述的是古代人有很多好的习惯,那么后文应该提到现代人恰恰相反.故答案为F.
20.B 上下文理解.根据后半句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.可知现代人不想像古代人那样生活.故答案为B.
