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。
例句:Just then I noticed, for the first time, that our master was wearing his fine green coat and his black silk cap.
当that从句是双宾语中的直接宾语时,that不可省。
例句:I can’t tell him that his mother died.
注意事项: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。
例句:I find it necessary that we should do the homework on time.
(二)由whether,if 引导的宾语从句
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。
例句:I wonder whether(if) they will e to our party.
只能用whether,不能用if引导的宾语从句
在带to的不定式前
例句:We decided whether to walk there.
在介词的后面
例句:I’m thinking of whether we should go to see the film.
在动词后面的宾语从句时
例句:We discussed whether we had a sports meeting next week
直接与or not连用时
例句:I can’t say whether or not thet can e on time.
只能用if不能用whether引导的宾语从句
if引导条件状语从句,意为“如果”
例句:The students will go on a piic if it is sunny. if引导否定概念的宾语从句时
例句:He asked if I didn’t e to school yesterday.
引导状语从句even if(即使)和as if(好象)时
例句:He talks as if he has known all about it.
(三)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常常是: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。
例句: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。
例句:None of us knows where these new parts can be bought.
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。
例句如下:
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?
主句是一般现在时,从句根据实际情况使用任何时态。
例句:The headmaster hopes everything goes well.
主句是过去时态,从句须用过去时态的某种形式。
例句:She was sorry that she hadn’t finished her work on time.
当宾语从句表示的是一个客观真理或者事实时,即使主句是过去时,从句也用一般现在时态。
例句:The teacher told his class that light travels faster than sound.
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.
