12. as long as 只要(引导条件状语从句) as long as(=so long as)用作连词,意思 是“只要,如果”,等于on condition that,provided(that),providing(that),if, only if。 as long as有时表示“像……那么久”。 only if用于句首,后接从句主谓倒装。 if only表示“要是……该多好”,句子用 虚拟语气。

完成句子 As long as you are happy (1)_______________________________ (只要你高兴),it doesn’t matter what you do. (2)I don’t mind Guy coming with us, provided he pays for his own meal __________________________________ (只要他自付餐费).
