賓語從句時態(tài)及語序:
時態(tài):
1、主句是一般現(xiàn)在時,從句根據(jù)實際情況使用任何時態(tài)。
例句:The headmaster hopes everything goes well.
2、主句是一般過去時,從句須用過去時態(tài)的某種形式。
例句:She was sorry that she hadn’t finished her work on time.
3、當(dāng)賓語從句表示的是一個客觀真理或者事實真理時,即使主句是過去時,從句也用一般現(xiàn)在時態(tài)。
例句:The teacher told his class that light travels faster than sound.
語序:
賓語從句的.語序是陳述句語序即:連接代詞/副詞+主語+謂語+其他成分。即:連接代詞/副詞+陳述句語序。例句如下:
1、I don’t know what they are looking for.
2、Could you tell me when the train will leave?
3、Can you imagine what kind of man he is?
賓語從句用什么時態(tài):
一般情況下賓語從句的時態(tài)必須和主句的時態(tài)保持一致:
一、如果主句的謂語動詞是一般現(xiàn)在時或一般將來時,賓語從句中的謂語動詞可根據(jù)意義的需要,使用任何一種時態(tài)。如:
1)Could you tell me when you will come again?你能告訴我你什么時候再來嗎?
2)I don't know if he arrived yesterday.我不知道他是否昨天到了。
3)Could you tell me what you were doing at eight last night?你能告訴我你昨晚八點在干什么?
