状语从句,as long as 怎么引导条件状语从句,怎么用,举一例引导原因状语从句since怎么用,举一例as怎么用,
as long as引导条件状语从句,可以加含can、be able to的句子、完成时(过去完成时、现在完成时)、现在时,但一般不接将来时.
例1:As long as you've offered,I accept.既然你已给我,我就接受.
例2:I will cooperate as long as I am notified on time.只要及时告诉我,我就会合作.
注意:一般不说I will go there as long as I will get permission.或I'm sure that I will come as long as I will finish the work.一般说:I will go there as long as I get permission.
since引导原因状语从句,相当于because与as much as,后面相当自由,什么时态都可以接,但是注意:since与so不能同时在句中出现,一次只能用一个!
例1:Since you're not interested,I won't tell you about it.既然你不感兴趣,那我就不告诉你了.
注意:不能说Since I can speak English fluently,so I will try this position again.要么把since去了,要么把so去了!
as与since的用法完全相同,而且也不能与so等在一个句子中共存.
例1:As I have been warned not to bring this knife onto the plane,I'd better still leave it to you.
as引导方式状语从句:
例1:Think as I think.像我这样去想.
例2:The hotel is quite comfortable as such establishments go.The sun is hot,as everyone knows.就设备而言,这个旅馆相当舒适.太阳非常热,这一点众所周知.
as if引导方式状语从句:
例1:It looked as if she were made of ice.她看起来似乎是冰做的.
例2:She spoke to me as if she knew me.她和我说话的神情,好像她早就认识我似的.(=as though)
as though引导方式状语从句(用法等同于as if):
例1:looked as though they had been quarreling.看起来他们刚才好象在吵架.
例2:The animal was walking as though it had hurt its leg.这动物走路的样子好像伤了腿似的.
