考研英語是很多考生的弱項，考生們在復習的時候一定要注意語法。下面是小編為大家整理收集的2017考研英語語法賓語從句和表語從句，僅供大家參考。
賓語從句
在謂語動詞、介詞、動詞不定式、分詞、動名詞之后都可以帶有賓語從句。某些形容詞如sure, happy, glad, certain, pleased 等之后也可以帶有賓語從句。
1.that 引導的賓語從句: that 沒有意義，在口語或非正式文體中常省略：如：
I really feel she’s making a mistake. 我的確感到她正犯錯誤。
James said (that) he was feeling better. 詹姆斯說他感到好些了。
Hearing that his son was badly wounded, he hurried to the hospital to see him. 聽說兒子受了重傷，他急忙趕到醫(yī)院去看望他。
I suggested that we should go home. 我建議我們回家去。虛擬語氣，that 一般不能省略。
2.whether/if (是否)引導的賓語從句：如果要突出“究竟是…還是不…”，常在whether 后面加or not; if 一般不與or not連用。如：
He asked me if/whether I knew John. 他問我是否認識約翰。
Let me know whether you can come or not. 你能來還是不能來，告訴我一聲。
3.在think, believe, suppose, expect 等動詞的賓語從句中，否定不用在從句中，而是將think 等詞變?yōu)榉穸ㄐ问健?/p>
For example:
I don’t think the film is interesting. 我覺得這部電影沒什么意思。
I don’t suppose we are going outing tomorrow. 我認為我們明天不會出去郊游。
4.如果從句作賓語而后面還有補語，為了保持句子的平衡，用it 作形式賓語，而將賓語從句放在句尾。常跟這樣的復合賓語的動詞有：make, find, see, hear, feel, think, consider, regard, take….for granted等。如：
George made it clear that he opposed this project. 喬治已明確表示他反對這個項目。it 代表that 引導的句子，作賓語，clear 是賓語補足語。

3.引導讓步狀語從句，等于“不管什么…”。注意狀語從句的語序。如：
