考生怎样快速定位雅思阅读中的主旨句

   　　考生在雅思阅读考试中怎样定位段落主题中的主旨句，特别是雅思阅读文章中更是要求考生要迅速抓准主题句，并且提取文章主干以及缩短雅思阅读考试的时间来答题，那么接下来西安新航道老师给的大家整理了有关考生怎样快速定位雅思阅读中的主旨句

   　　考生怎样快速定位雅思阅读中的主旨句

   　　雅思阅读考试中段落主旨句出现多的位置是在段首;英语文章中多的也就是演绎型的写法，由于西方人喜欢开门见山，因此考生们要常常会在雅思阅读中每一段的首句话就交代出这段话的主旨句;

   　　就比如：As a child grows up，he learns how to behave in ways that is appropriate tothe society into which he is born. That is to say，he acquires the patterns ofbehavior that are accepted as normal in his society. This process of sociallearning is generally referred to as socialization. By socialization，then，wemean the process whereby individuals learn the rules，values and practices of thesociety in which they live.

   　　上面首句就是整体段落中的介绍，第二句话也就是首句话的解释，第三句中代指前一句话中的学习成熟过程，在后一句话中也是对社会化的解释，因此考生们可以确定首句话就是段落的主题句;

   　　除了首句之外考生的主题句也可能会出现在阅读文章段首位置的第二句，就比如：

   　　What then makes people left-handed if it is not simply genetic?Otherfactors must be at work and researchers have turned to the brain for clues. Inthe 1860s the French surgeon and anthropologist，Dr Paul Broca，made theremarkable finding that patients who had lost their powers of speech as a resultof a stroke (a blood clot(凝结) in the brain) had paralysis(麻痹) of the right halfof their body. He noted that since the left hemisphere of the brain controls theright half of the body，and vice versa(反之亦然)，the brain damage must have been inthe brain's left hemisphere，Psychologists now believe that among right handedpeople，probably 95 percent have their language centre in the lefthemisphere，while 5 percent have right-sided language.

   　　上面这段可以看出主旨句是在第二句话，也即是其他因素起到了作用，研究者也将线索转向人类大脑方面;

   　　另外一个常出现段落主题句的位置则是段尾，这种现象也经常出现在归纳型的文章中，也就是归纳型先陈述现象然后总结规律;
