賓語從句的用法及練習題
賓語從句是名詞性從句的一種。在主從複合句中充當賓語，位於及物動詞、介詞或複合謂語之後的從句稱為賓語從句。賓語從句分為三類：動詞的賓語從句，介詞的賓語從句和形容詞的賓語從句。那麼你知道賓語從句的用法嗎?下面跟著小編一起來學習一下，希望對大家的學習有所幫助!
一、賓語從句的用法
在複合句中作主句的賓語，引導詞有：
連詞：that that 常可省略,whether, if
代詞：who, whose, what ,which
副詞：when ,where, how, why 等。
一that引導的賓語從句在非正式場合that可以省略
可跟that從句做賓語的動詞有：
say, think, insist, wish, hope, demand, imagine, wonder, know, suppose, see, believe, agree, admit, deny, expect, explain, order, command, feel, dream, suggest, hear, mean, notice, prefer, request, require, propose, declare, report等。
例句：The boy believes that he will travel through space to other planets.
注意事項：當主句謂語動詞是 think, believe, suppose, expect 等詞，而賓語從句的意思是否定時，常把否定轉移至主句表示。
例句：I don’t think it is right for him to treat you like that.
在以下情況中that不能省略
當句中的動詞後接多於兩個由that引導的賓語從句時，第一個that可省，但後面的that不可省。
例句：He said that you were too young to understand the matter and that he was asked not to tell you.
當主句的謂語動詞與that賓語從句之間有插入語時，that一般不可省。
例句：Just then I noticed, for the first time, that our master was wearing his fine green coat and his black silk cap.
當that從句是雙賓語中的直接賓語時，that不可省。
例句：I can’t tell him that his mother died.
注意事項：許多帶複合賓語的句子，that引導的賓語從句經常移到句子後部，而用it作形式賓語。
例句：I find it necessary that we should do the homework on time.
二由whether,if 引導的賓語從句
由whetherif引導的賓語從句，實際上是一般疑問句演變而來的。意思是“是否”。賓語從句要用陳述句語序。一般說來，在賓語從句中whether與if可以互換使用，但在特殊情況下if與whether是不能互換的。
例句：I wonder whetherif they will come to our party.
只能用whether，不能用if引導的賓語從句
在帶to的不定式前
例句：We decided whether to walk there.
在介詞的後面
例句：I’m thinking of whether we should go to see the film.
在動詞後面的賓語從句時
例句：We discussed whether we had a sports meeting next week
直接與or not連用時
例句：I can’t say whether or not thet can come on time.
只能用if不能用whether引導的賓語從句
if引導條件狀語從句，意為“如果”
例句：The students will go on a picnic if it is sunny.
if引導否定概念的賓語從句時
例句：He asked if I didn’t come to school yesterday.
引導狀語從句even if即使和as if好象時
例句：He talks as if he has known all about it.
三連線代詞和連線副詞引導的賓語從句
這樣的賓語從句實際上是由特殊疑問句變化而來的，賓語從句要用陳述句語序。用於這種結構的動詞常常是：see, say, tell, ask, answer, know, decide, show, find out, imagine, suggest, doubt, wonder, discover, understand, inform, advise等。
英語中的連線代詞有：who,whom,whose,which,what,在句中擔任主語、賓語、定語或者表語。
例句：Can you tell me whom you are waiting for?
英語中的連線副詞有：when,where,why,how，在句中擔任狀語的成分。
例句：None of us knows where these new parts can be bought.
