【宾语从句的连接词】

 1. 当宾语从句是陈述句时,用that引导。
如:Even the teacher agreed that Martin was wasting his time.
甚至老师也认同马丁在浪费时间。
注意:引导词that用于下列情况时不可省略
(1) 当宾语从句的主语是that时。
如:He says that that is a useful book.
他说那是一本有用的书。
(2) 当从句前有插入语时。
如:It says, on the card, that it is made in China.
卡片上写着那是中国制造。
(3) 当宾语从句中含有主从复合句时。
如:Our teachers believe that if we did that, we would concentrate more on our clothes than our studies.
我们的老师认为如果我们那样做的话,我们会把更多的精力放在衣服上而不是学习上。
(4) 当两个或多个宾语从句由并列连词连接时,除第一个从句中的that可以省略外,其余从句中的that都不可以省略。
如:He said (that) the film was very interesting and that he enjoyed seeing it very much.
他说这部电影非常有趣,并且他非常喜欢看。
 2. 含疑问语气的句子构成宾语从句时用whether或if连接,句尾的标点符号取决于主句。
如:“Do you like watching TV?” He asked me.
=He asked me if/whether I liked watching TV.
他问我是否喜欢看电视。
I don't mind if it's something I don't need.
我不介意它是否是我不需要的东西。
注意:if多用于口语中,whether多用于书面语或一些较正式的场合,一般情况下二者可以互换。但是在下列情况下只用whether而不用if引导宾语从句:
① 从句后面有“or not”时。如:
I wonder whether I'll catch the first bus or not.
我不知道能否赶上第一班公交车。
② 后面跟动词不定式时。如:
I can't decide whether to stay.
我不能决定是否留下。
③ 引导的从句作介词宾语时。如:
Everything depends on whether we have enough time.
一切都取决于我们是否有足够的时间。
④ 用在discuss后面的宾语从句中。如:
We discussed whether he could come on time.
我们讨论他是否能按时来。
(3) 当宾语从句是特殊疑问句时,引导词用原句中的特殊疑问句。此时引导词都有本身的词义,并且在句中作一定的成分,因此不能省略。如:
I don't know what they are going to do.
我不知道他们打算干什么。
Do you know how they found the place?
你知道他们是怎么找到这个地方的吗?
 3. 连接代词what, who, whom, whose, which引导宾语从句时,连接代词在从句中作主语、宾语、表语、定语等,不能省略。如:
We now know what was happening in Bell Tower neighborhood.
现在我们知道钟楼小区发生什么事情了。
She knew what was happening because she learnt about underwater earthquakes at school only a few weeks earlier.
她知道发生了什么,因为仅几周前她在学校学习了水下地震方面的知识。
 4. 连接副词when, where, how, why等引导宾语从句时,连接副词在从句中作状语,不能省略。如:
Do you know when basketball was invented?
你知道篮球是何时发明的吗?
