如题所述

cover如果没有做谓语动词的话后面也没有接介词那这个词应该用动词形式。
宾语从句

1

概述

置于动词、介词等词性后面起宾语作用的从句叫宾语从句。宾语从句的语序必须是陈述语序。谓语动词、介词、动词不定式,v.-ing形式后面都能带宾语从句。有些形容词(afraid,sure,glad等)之后也可以带宾语从句。

2

宾语从句的特点
宾语从句可以作及物动词、介词及形容词的宾语。
宾语从句的语序一律用陈述句语序。
连接词that 引导宾语从句在句中无词义,不充当句子成份,多数情况下可以省略。
whether和if都可引导宾语从句,但whether 后可紧跟or not;whether从句可作介词的宾语。
如果从句太长,可以用形式宾语it.

3

宾语从句中引导词的用法

在复合句中作主句的宾语,引导词有:

连词:that(that 常可省略),whether,if

代词:who,whose,what,which

副词:when,where,how,why等。
that 引导的宾语从句(在非正式场合that 可以省略)

①可跟that从句做宾语的动词有: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。

如:The boy believes that he will travel through space to other planets.

注意:当主句谓语动词是think,believe,suppose,expect 等词,而宾语从句的意思是否定时,常把否定转移至主句表示。

如:I don't think it is right for him to treat you like that.

② 在以下情况中that不能省略

⑴ 当句中的动词后接多于两个由that引导的宾语从句时,第一个that可省,但后面的that不可省。

如:He said(that)you were too young to understand the matter and that

he was asked not to tell you.

⑵ 当主句的谓语动词与 that 宾语从句之间有插入语时,that一般不可省。

如:Just then I noticed for the first time,that our master was wearing

his fine green coat and his black silk cap.

⑶ 当that 从句是双宾语中的直接宾语时,that不可省。

如:I can't tell him that his mother died.

注意:许多带复合宾语的句子,that引导的宾语从句经常移到句子后部,而用it作形式宾语。

如:I find it necessary that we should do the homework on time.
由whether,if引导的宾语从句

① 由whether(if)引导的宾语从句,实际上是一般疑问句演变而来的。意思是“是否”。宾语从句要用陈述句语序。一般说来,在宾语从句中whether与if可以互换使用,但在特殊情况下if与whether是不能互换的。

如:I wonder whether(if)they will come to our party.

② 只能用whether,不能用if引导的宾语从句

⑴ 在带to的不定式前

如:We decided whether to walk there.

⑵ 在介词的后面

如:I'm thinking of whether we should go to see the film.

⑶ 在动词后面的宾语从句时

如:We discussed whether we had a sports meeting next week.

⑷ 直接与or not连用时

如:I can't say whether or not thet can come on time.

③ 只能用if不能用whether引导的宾语从句

⑴ if引导条件状语从句,意为“如果”

如:The students will go on a picnic if it is sunny.

⑵ if引导否定概念的宾语从句时

如:He asked if I didn't come to school yesterday.

⑶ 引导状语从句even if(即使)和as if(好像)时

如:He talks as if he has known all about it.
连接代词和连接副词引导的宾语从句

这样的宾语从句实际上是由特殊疑问句变化而来的,宾语从句要用陈述句语序。

用于这种结构的动词有:

see, say, tell, ask, answer, know, decide, show, find out, imagine, suggest, doubt, wonder, discover, understand, inform, advise等。

英语中的连接代词有:who,whom,whose,which,what,在句中担任主语、宾语、定语或者表语。

如:Can you tell me whom you are waiting for?

英语中的连接副词有:when,where,why,how,在句中担任状语的成分。

如:None of us knows where these new parts can be bought.

4

宾语从句的语序

宾语从句的语序是陈述句语序即:连接代词/副词+主语+谓语+其他成分。

如:I don't know what they are looking for.

Could you tell me when the train will leave?

Can you imagine what kind of man he is

cover如果没有做谓语动词的话后面也没有接介词那这个词应该用什么形式?为了说明这个问题,我想简要说明一什么是谓语?一个完整的英语句子,至少有两部分组成(祈使句除外,因为祈使句也是省略主语或其他成分的句子)主语就是句子叙述的主体,表明这句话描述说明什么,谓语就是帮助主语描述或说明的成分。谓语由动词构成。
注意:有单个的动词或动词短语构成的叫简单谓语;
有情态动词或助动词+动词构成叫复合谓语。另外,系动词+表语的结构归纳为复合谓语,因为表语的作用就是表面和描述主语的性质特征的成分,系动词起到联系主语和表语纽带。比如:他是个教师。主语是he ,a teacher 就是表语,但这样不是句子啊,只好用is这个系动词来把他们两个系在一起。况且,系动词也不能单独作谓语。比如:he is ,you are ,I am 就不是句子。
简单说,有系动词必须有表语,有表语必须有系动词,谁也离不开谁。
必须举例说明了:I like English.简单动词

He is looking for his watch.动词短语

He can swim. (情态动词+动词)

He must finish his homework before 6 o’clock. (情态动词+动词)
