雅思閲讀同義詞轉換的詞組

Example 1：

原文：Computers are gainingin popularity， despite their cost.

題目：Computers are morepopular than they used to be.

原文當中的gaining in popularity題目中用morepopular than they used to be作為替換。兩者在意思上屬於完全一致的'同義轉換，因此答案為TRUE。

Example 2：

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

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

原文當中的biologically用題目的inbiological terms作為替換。Become則由issaid to be作為替換。但是原文當中的die在題目中變成了exist， 直接相反的意思。介於最後這一處的轉換與原文信息不符，可以判斷出此題答案是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：根據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意思等同於inthe domain of在....領域，因此答案為chemistry。
