10.Recently some American scientists have given a useful piece of advice to people in industrialized(工業(yè)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(家養(yǎng)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(那樣的話),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".

分析 本文屬于說(shuō)明文閱讀,作者通過(guò)這篇文章主要向我們描述了研究發(fā)現(xiàn)古代人比現(xiàn)代人更加健康,主要是由于飲食的問(wèn)題.

解答 66.C.推理判斷題.根據(jù)前文They say people should eat more of the same kind of food eaten by humans living more than 10,000years ago人們應(yīng)該吃1萬(wàn)年前人們吃的東西,在那種情況下,人們將活得更為健康;故選C.
67.E.推理判斷題.根據(jù)前面提及的this had led to new kinds of sicknesses.以及后面的they are called"diseases of civilization".可知古代不了解這些新的疾。还蔬xE.
68.B.推理判斷題.根據(jù)前文enjoyed very little alcohol or tobacco,probably none.可知古代人不抽煙喝酒,接下來(lái)應(yīng)該說(shuō)古代人還經(jīng)常鍛煉;故選B.
69.D.推理判斷題.根據(jù)前面三句話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可知古代人有很多好的習(xí)慣,而現(xiàn)代人恰恰相反;故選D.
70.F.推理判斷題.根據(jù)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.可知現(xiàn)代人不想像古代人那樣生活;故選F.

點(diǎn)評(píng) 七選五閱讀是完成性閱讀,和完形填空很類似,不同的是一個(gè)選詞,一個(gè)選句子.解題時(shí),要注意上下文語(yǔ)境,充分考慮信息詞(選項(xiàng)中和空格前后句子中相同或相近的詞),選出最符合語(yǔ)境的句子.
