我來和你一起總結(jié)一下這類情況：
1.主句將來時(shí),從句用一般現(xiàn)在時(shí)替換將來,如if,when,after,the minute等引導(dǎo)的時(shí)間、條件等狀語從句中：
I'll tell her when she comes tomorrow.
I shall tell her the minute she gets here.
The next time you come,he will be a grown-up.
2.主句一般現(xiàn)在時(shí),從句現(xiàn)在完成時(shí),一般現(xiàn)在時(shí)強(qiáng)調(diào)現(xiàn)在的事實(shí)或結(jié)果
They tell me that you've agreed to it.
3.主句一般過去時(shí),從句現(xiàn)在完成時(shí),一般過去時(shí)強(qiáng)調(diào)未指明的過去時(shí)間
They told me that you've agreed to it.
4.定語從句中用一般現(xiàn)在時(shí)代替將來時(shí),主句用一般將來時(shí)
He will give you anything you ask for.
Anyone who does it will get a gift.
5.一般現(xiàn)在時(shí)與一般過去時(shí)連用,因?yàn)闀r(shí)間點(diǎn)選取不同,一般現(xiàn)在時(shí)代表一種客觀事實(shí),一般過去時(shí)代表過去某一次的行為
As the city does not have many entertaining places to go,we treated the foreign friends to some real Chinese food.
6.一些特別的句型中主句用一般現(xiàn)在時(shí)主句用一般完成時(shí)It/This is ...that..
This is the first time that I've heard her sing.
This is the best movie that I've ever seen.
7.主句用過去時(shí),從句用過去完成時(shí)
She said that she had never been there.
還有一些,由于時(shí)間選取的不同,會(huì)采取不同的時(shí)態(tài)來表達(dá),平時(shí)遇到時(shí)多分析,積累.
