词语用法

词义讲解

常见错误

prep.(介词)

before可用于表示时间。首先，可以表示“先于，在…以前”，其后可以跟表示具体日期、时间等的名词或数词，也可以跟表示时间或动作的名词。其次，可以表示“在做…之前”，后接 v -ing。再次，可以表示“紧接在…之前”。before用于否定句还可表示“直到…为止”。注意before之后只能接表示时间点的名词，而不能接表示时间段的名词。

before可用于表示动态或静态的位置，意思是“在…之前”，与behind相对。

before可用于表示顺序或排列上的“在…之前”或“居于…之前”，与after相对。引申可用于表示比较，即在等级、价值、重要性、能力等方面的“在先”“优于”“重于”。再引申则可用于表示对某事物的优先选择，即“宁可”或“与其…宁可”。

before还可表示“面对，在…眼前，在…面前”“有待于去完成”“在审理中，由…考虑”“在…压力下”等。

conj.(连词)

before主要引导时间状语从句，意为“先于”“…之后才”“(不多久)就…”。当主句是将来时时，从句谓语动词须用现在时；当主句是一般过去时或过去完成时时，从句常用过去时。before引导的时间状语从句不能用于否定式。

before还可用于barely〔scarcely〕...before结构，意为“刚…就…”。

before还可引导让步状语从句，意思是“宁愿…也不…”。

before引导的从句常用省略句型。

adv.(副词)

before用作副词时,意思是“以前,在前面”,表示从较近的过去至较远的过去。用作时间状语泛指以前、不与具体时间连用时，谓语动词可以用一般过去时,也可用现在完成时,前者只表示“过去发生过”,后者则强调“对现在有影响”。

before与具体时间连用时,一般置于其后，谓语动词通常用过去完成时。

before也可表示空间或位置的“在前，在前面”，还可表示运动“到前面”。

prep.(介词)

before, by

这两个词都可表示“在…之前”。before所表示的时间不包括其宾语所指时间在内,与之连用的动词可以是延续性动词,也可以是瞬间动词; by所表示的时间包括宾语所指的时间在内,因而常译成“不迟于…”。

conj.(连词)

before, for

这两个词都可表示时间，但before可用于肯定句和否定句，表示将来的一个时间点；而for只用于否定句，表示将来的一个时间段。例如：

The sun will not rise before six o'clock.

太阳在六点钟前不会升起。

The sun will not rise for an hour.

太阳在一个小时之内不会升起。

adv.(副词)

before, in front of

这两个词(组)都可表示“在…前面”，在表示位置或“当…的面”时两者常可替换。其区别是：

1.表示具体事物如建筑物之前时用before较正式，而用in front of更普通。

2.在表示人的名词前和较抽象化或比喻用法时通常用before。

3.before还有引申义，例如：

A tree stands in front of the home.

房子前面有棵树。

A tree stands before the door of the house.

房子前面有棵树。

第二个句子使用before暗示这棵树可“给房子遮阴”或“给人出行造成困难”等意。

conj.(连词)

铃还没响，同学们就走出去了。

误 The students went out before the bell didn't ring.

正 The students went out before the bell rang.

before引导的时间状语从句不能用于否定句。
