雅思阅读同义词转换：词组.

　　词组的转换一般情况下是雅思阅读同义词转换的一个衍生。当一个词无法用另一个同义词到位地解释时，可能会出现用词组解释的情况。另外如果本身就是词组的形式，那么通常来讲还是会用词组的形式进行解释。

　　例如：

　　Example 1:

　　原文：Computers are gainingin popularity, despite their cost.

　　题目：Computers are morepopular than they used to be.

　　原文当中的gaining in popularity题目中用morepopular than they used to be作为替换。两者在意思上属于完全一致的同义转换，因此答案为TRUE。

　　Example 2:

　　原文：Biologically, aspecies becomes extinct when its last individual dies.

　　题目：In biological terms,a species is said to be extinct when only one individual exists.

　　原文当中的biologically用题目的inbiological terms作为替换。Become则由issaid to be作为替换。但是原文当中的die在题目中变成了exist, 直接相反的意思。介于最后这一处的转换与原文信息不符，可以判断出此题答案是FALSE。

　　Example 3:

　　There were severalreasons for the research into plastics in the nineteenth century, among themthe great advances that had been made in the field of _____and the search foralternatives to natural resources like ivory.

　　解析：根据nineteenth century定位到文中第二段......Theimpetus behind the development of these early plastics was generated by anumber of factors- immense technological progress in the domain ofchemistry,.......其中，in the field of意思等同于inthe domain of“在....领域”，因此答案为chemistry。

　　In recent years, manyof them have been obliged to give up their _____ lifestyle, but they continueto depend mainly on _____ for their food and clothes.

　　解析：根据上下文定位到文中Overthe past 40 years, most have abandoned their nomadic ways and settled in theterritory&aposs 18 isolated communities, but they still rely heavily on nature toprovide food and clothing. 因为大多数同学都认识abandon, 更知道giveup是“放弃”的意思，属于单词与词组的替换，因此第一个空填nomadic,lifestyle“生活方式”与ways替换，dependmainly on与rely heavily on属于词组与词组的替换，意为“依赖......”，答案为nature。

　　综上所述，同义词替换在雅思阅读中的重要作用显而易见。澳际小编提醒广大考生在平时一定要注意多积累，比如在背单词的时候，就不能只满足于记住单词本身，还应该多想想这个单词有什么同义、近义词，以及词组的代换，这样在雅思阅读中就能取得好的成绩。
