【正文】
① As long as you do your best, we’ll be happy. 只要你盡力,我們就很開心了。 ② As long as you need me, I’ll stay. 只要你需要我,我就留下。 當由 as long as引導的條件狀語從句中的謂語為 be動詞,且從句的主語和主句的主語相同時,則從句的主語和 be動詞可以省略。如: I’m sure we are safe as long as ( we are) in his care. 我深信只要在他的保護下,我們就會平安無事。 【 延伸 】 as long as還有以下用法: ( 1)意為“與 …… 一樣長”。如: ① This river is as long as that one. 這條河與那條河一樣長。 ② He lived abroad as long as five years. 他曾經(jīng)住在國外長達五年之久。 ( 2)意為“既然”,相當于 since。如: As long as you are going, I’ll go too. 既然你要去,那么我也去。
