词语用法
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)
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。
