Our bodies have not been able to deal with these changes in lifestyle and this had led to new kinds of sicknesses._72_ So they are called “diseases of civilization”Many cancers and diseases of the blood system are examples of such diseases.AStone Age people lived a simple life.BBut today, we enjoy eating a lot of these.CIn that case, they would live much healthier.DAncient people also got lots of physical exercise.2. 代词线索法英语表达中代词出现的频率极高，代词的作用无非是指代前面提及的名词或形容词概念，巧妙利用这样的指代关系和根据代词的单复数差异可以准确而快速地解题。 it可指代单数名词或整个句子；they或them指代复数名词；one指代单数可数名词；that指代不可数名词或句子；this指代单数名词或句子；these 或those指代前句的复数名词。【例2】_73_ They say the first step is to admit that you are angry and to recognize the real cause of the anger，.ADoctors say the solution is learning how to deal with anger. BHe said that laughter is much healthier than anger. CAnger is a normal emotion that we all feel from time to time. 3逻辑关系衔接法 过渡性句子可以从细节逻辑上判断可分为：.并列关系：First(ly)，Second(ly)，.；First, then/ next，.；In the first place, in the second place.；for one thing, for another thing，.；then /next, finally/last 等。.递进关系：too, also, besides, further, furthermore, moreover, whats more, in addition, as well, to make matters worse, not.but., not only.but also等。因果关系： so /therefore, thus, consequently(结果), as a result (of), so/such.that.，so that.等。转折对比关系：but, however, yet, while /though, or /otherwise, on the contrary, instead, nevertheless(然而), still, yet, on the contrary, in contrast/comparison 等。概括归纳关系：in short, in brief, in summary, generally speaking, in general, to conclude, in conclusion, in a word, on the whole, to sum up 等。【例3】_ Second, your notes are excellent materials to refer to when you are studying for a test.AYou must write your notes on separate paper. BThere are three practical note taking methods. CFirst, the simple act of writing something down makes it easier for you to understand and remember it. 4. 问答法【例4】One may ask why there are so many people smoking?_ .
