条件状语从句 连词有:if, unless, as long as (1) if引导的条件状语从句 翻译为:"如果", 时态遵循主将从现,可以与祈使句进行转换,如: If he said that,he can't be telling the truth. 如果他说了那样的话,他不可能是说实话。 You ____________ (pass) the exam if you _________ (study) hard. = _______________________________________________________________. Hurry up, or you'll be late. = _____________________________________________________. (2) unless"除非"或"如果......不"引导的条件状语从句 unless引导的是否定条件状语从句,在意义上相当于if...not,而且语气较强,一般不用于虚拟语气。如: You'll be late unless you hurry. = _____________________________________________________. 你会迟到的,如果不赶快的话。 (3) as long as意为"只要;如果"。如: __________________________________, we can play. 只要不下雨我们就能玩。 (责任编辑:admin) |
