聽力測試題有很多對(duì)話常通過某種否定形式來表示肯定含義,或是利用肯定形式表示否定意義。其目的是考查學(xué)生的快速反應(yīng)能力和對(duì)基礎(chǔ)知識(shí)掌握的程度。
常見的以否定形式表示肯定意義的結(jié)構(gòu)有:
cannot wait+不定式或can hardly wait+不定式(急于……,迫切希望……);cannot與much(或too,enough,sufficiently,over構(gòu)成的合成詞)連用(無論怎么也不為過);cannot help doing(禁不住做……);cannot but do(不得不,必然);cannot help but do(不得不);have no choice/alternative but to do(除非……外別無選擇,非做……不可);nothing but(只有,只不過)。另外,還可以通過各種比較結(jié)構(gòu)來表示肯定含義,最常用的有:nothing less than(和……一模一樣,完全是);more A than B(與其說是B,不如說是A或是A而不是B);less A than B(與其說是A,不如說是B或是B而不是A);not so much A as B(是B而不是A);A not so... as B(A比B……),表達(dá)的正好是原結(jié)構(gòu)中形容詞或副詞的反義。
常見的以肯定表示否定的意義的有:
anything but(根本不);used to(過去常常,是對(duì)現(xiàn)在的情況的否定,說明現(xiàn)在已不這樣做);too... to...(太……以致不……,這一結(jié)構(gòu)的不定式表示否定意義);prefer... to...(該短語否定的是介詞短語部分,表示“不喜歡或不會(huì)做”等);would rather... than(寧愿……而不,這一結(jié)構(gòu)否定的是than后的動(dòng)詞,would... rather than與其用法相同)。
