雅思阅读同义词转换：词组

　　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 theterritorys 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。
