词语用法

词义讲解

常见错误

词源解说

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。

v.(动词)

prevent, block

这二者都可表示“阻止”,其区别是：

prevent表示某种障碍阻止某人做某事, block指有效地堵住了所有的通道,使人、物等无法通过。例如:

Bad weather prevented us from starting.恶劣的天气使我们不能动身。

Heavy snow blocked our road.大雪堵住了我们的去路。

v.(动词)

她企图阻止他去,但他还是去了。

误 She prevented him from going, but he still went.

正 She tried to prevent him from going, but he still went.

析 prevent表示“阻止”成功,如果阻止未成功则应该说try to prevent。

谁也不能阻止这个计划的实现。

误 No one can prevent the plan from carrying out.

正 No one can prevent the plan from being carried out.

析 在prevent...from...结构中,若介词from后的宾语有被动意义,则要用动名词的被动形式。

没有什么能阻止他独立作环球航行。

误 Nothing could prevent him to sail round the world single-handed.

正 Nothing could prevent him from sailing round the world single-handed.

正 Nothing could prevent him sailing round the world single-handed.

正 Nothing could prevent his sailing round the world single-handed.

析 表示“阻止某人做某事”,可以说prevent sb from v -ing, prevent sb v -ing或prevent sb's v -ing,但不能说prevent sb to- v sth。

☆ 15世纪初期进入英语，直接源自拉丁语的prventus，意为妨碍。
