用法辨析
- 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。
- prevent指“阻止成功”,如果阻止了,但是没有成功,不可用prevent。如果说她阻止他去,实际上他的确没有去,可以说She prevented him from going.但是他不听劝,还是去的话,要说She tried to prevent him from going, but he still went;
- prevent加宾语时,宾语后不可接不定式。She prevented him to go. 该句是错误的表达。
v. (动词)
