宾语从句的引导词that
八种不能省略的情况
that在引导宾语从句时也并不是任何情况下都可以省略。在以下八种情况,that不能省略。
1.宾语从句前有插入语
Just then I noticed, for the first time, that our minister was wearing his fine green coat and his black silk cap.
We hope, on the contrary, that he will stay at home with us. 恰恰相反,我们希望他和我们呆在家里。
2.宾语从句紧接在间接宾语后时,that不能省略。
The teacher advised us that we should pay enough attention to reading and writing.
I tell you that learning English with your ears is the most effective way the native speakers usually use.
He told me that he was leaving for Japan.
Everybody could see what happened and that Tom was frightened.
He said (that) the exhibition was excellent and that he wanted to visit it once more.
如果第二个that省略了,那么就不能确定he wanted to visit it once more 是从句还是he said的并列句
We realize that hiking can be hard work and believe that hikers need all our help.
3. that在与之并列的另一个宾语从句之后。
He said (that) the book was very interesting and that(不省略) all the children like to read it.他说那本书很有趣,所有小孩都喜欢读。
4.在“it(形式宾语)+补语”之后和有形式宾语it时。如:
I think it necessary that he should stay here. 我们认为他有必要留在这里。
I thought it strange that he failed to call me.
I think it necessary that you should study English well.
I think it necessary that he should stay here.
You may depend on it that I shall always help you.
5. that从句单独回答问题时。如:
—What did he hear? 他听说了什么事?
—That Kate had passed the exam. (他听说)凯特考试及格了。
6. 在except,but,in等介词后。如:
I know nothing about him except that he is from the south.
His article is very good except that there are only a few unfit sentences.
I know nothing about my new neighbour except that he works in a laundry.
7. 位于句首时。如:
That our team will win, I believe. 我相信我们队会赢。
That he ever said such a thing I simply don’t believe.
8. 在较为正式或不常用的动词(如reply, object)后。如:
He replied that he disagreed. 他回答说他不同意。
9.在宾语从句中,that 之后紧跟代词作主语或定语的that或this时,that不能省略。
上句中,如果省略了第一个that ,那么第二个that就会产生歧义,因为在主谓都在的情况下,后面的句子肯定是宾语从句,但that在名词性从句中是不能做句子成分的。
动词doubt的宾语从句引导词:
doubt在肯定句中,其宾语从句的引导词可用if/whether。
I doubt whether/if he is at home.
I doubt whether/if he can speak English.(肯定句)
Doubt在否定句/疑问句中,其宾语从句的引导词只能用that。
I don’t doubt that our team will win.
I do not doubt that he can speak English.(否定句)
Do you doubt that he can speak English?(疑问句)
