有时作者运用对比的手法来表现事物之间的差异.在进行对比的过程中,作者必然会用一些互为对应、互为反义的词语,使不同事物的特点更为突出.通过上下文的逻辑关系,从对两种事物或现象进行对比的描述中,读者可以根据其中一个熟悉的词推断出另一个生词的词义来.

[例]Inthepasttheworldseemedtoruninanorderlyway.Now,however,everythingseemstobeinastateofturmoil.
此句中,以信号词however为线索,可以看出作者把现在的事情与过去相比.过去是"inanorderlyway",而现在是"inastateofturmoil",过去是秩序井然,那么现在则是相反,那就是一片混乱.
