賓語從句可以分為三類
（1）動詞的賓語從句
1.1 大多數(shù)位于動詞后面
? ? ?Eg：I hope you can join us in the game.
1.2 有些是“動詞+副詞”后
? ? ?Find out / point out / figure out / turn out/ figure out
? ? ?Eg：Can you figure out what the poet really means in this poem?
1.3 有些動詞短語后面
? ? ? Make sure / make up one’s mind / keep in mind
? ? ? Eg：we should keep in mind that sports can be a great boost to our health.
(2) it 作形式賓語代替賓語從句
第一類動詞： find/ feel/ think/ consider/ make / believe/ guess/ suppose /assume等后面有賓語不足語時，需要用it 作形式賓語而將that引導的真正的賓語從句后置。
? ? Eg：I think it necessary that we do some sporting.
第二類動詞： 帶賓語從句時需要在從句前面加it。這類詞：hate / like/ dislike/ appreciate/ depend on/ see to /
? ? Eg: I hate it when they talk without considering other’s feeling.
但是如果賓語從句是WH-類引導的，其后面有to be 短語作賓語補足語，不可以用it 代替。
? ? We all consider what you said to be unbelievable. (right)
? ? We all consider it to be unbelievable what you said .(wrong)
(3) 形容詞后的賓語從句
Adj: sure / certain/ glad/ pleased/ happy / afraid / sorry 等等。
Eg：I am not sure whether you will come or not.
3. 賓語從句的語序問題
（1）要把疑問語氣改為陳述語氣
? ? ?Eg：I could not understand why you refused this good opportunity.
(2) 賓語從句引導詞that 的省略問題
? ? That在一般情況下可以省略，但在一下情況下不可以省略。
?a. 一個動詞帶有兩個或多個并列的賓語從句，第一個that可以省略，第二個和以后的都不可以省略。
? ? ?Eg：Our parents tell us that we should be honest and that we need learn how to share our feelings with others and that we must know how to learn from others.
?b. 賓語從句是雙賓語中的直接引語
? ? ? Eg：lily told me that she would not come to school tomorrow.
?c. 有it 作形式賓語
? ? ? Eg：we all consider it important that children need enough sleep.
(3)賓語從句的否定轉移
? 條件：1 主語是第一人稱
? ? ? ? ? ?2 謂語動詞是think/ believe / suppose/ imagine/ guess / expect
? 意義：“主句否定形式，從句否定意義”
? ? Eg: I don’t believe that you are a good guy.
(4)賓語從句的時態(tài)
? ? 賓語從句的謂語動詞時態(tài)通常受到主句時態(tài)的影響
?1.（主現(xiàn)，從不變）主句為一般現(xiàn)在時態(tài)，賓語從句根據(jù)需要選擇時態(tài)。
? ? ?Eg：I know that you did not finish your homework yesterday.
?2.（主過，從過）主句為一般過去時態(tài)，賓語從句選擇與過去有關的時態(tài)。
? ? ?Eg：he told me that he had been to America .
3.(主過，從真理現(xiàn))主句為一般過去時態(tài)，賓語從句如果是客觀事實和永久不變的真理，用一般現(xiàn)在時態(tài)。
? ? ?Eg：My mother once told me that the sun rises in the east and sets in the west.
(5)運用虛擬語氣的情況
? ? 建議 suggest 、advise、propose；
? ? 要求demand 、desire、request；
? ? 決定 decide；
? ? 命令 order、command、require；
? ? 堅決主張 insist；
? ? 等動詞后跟賓語從句，用（should）+v.（虛擬語氣）
