prevent搭配
v.(动词)
prevent的基本意思是“止”,可表示“阻止”(某计划或意图)、“防止”(已有兆头的险事、恶事)、“制止”(某人做某事)等,强调做好预先的防备或准备,含有“阻止成功”的意味。
prevent主要用作及物动词,可接名词、代词或动名词作宾语,不接不定式作宾语。用作prevent宾语的动名词前常有物主代词或者名词,人称代词宾格表示其逻辑主体。prevent可用于被动结构。prevent偶尔也可用作不及物动词。
表示“阻止做某事”,可用prevent sb/sb's v -ing,也可用prevent sb from v -ing,这几种用法在意义上没有明显的区别。
用作动词(v.)
