雅思阅读同义词转换的词组

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mpetus 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。
