1.由that指导，因为that没有任何意义，也不充任任何句子成份。是以that在非正式体裁中可以省略。这种宾语从句凡是表达一种报告意义。
e.g.He told me (that) he would go to Wuhan.
Tom says (that) he must study hard.
She told me (that) she was a student.
(1)若是由and毗连两个并列的宾语从句时，第二个that则不克不及省略。
e.g.She said she liked English very much and that she didn’t like math at all.
(2)常接that指导的宾语从句的谓语动词有：believe, expect, explain, feel, hear, hope, imagine, prefer, promise, report, say, see, tell, think, understand, warn, wish等。
2.由毗连代词或毗连副词who, whose, what, which, when, where, how, why指导，含有“谁、甚么、哪一个、何时、甚么处所、怎么、为甚么”等特别疑难意义。
e.g.Do you know who they’re talking about?
Can you tell me what they’re looking for?
I don’t know where she has gone.
I wonder how she can find us.
She didn’t tell me where her hometown was.
3.由隶属连词whether和if指导，含有“是不是，可否，对否，有否”等一般疑难意义。
e.g.She asked me if I could help her.
Jim wanted to know whether I had taken his English book.
Please tell me whether you can come or not.
在这种
宾语从句中要注重两点：
(1)if指导宾语从句和状语从句的区分
if指导宾语从句时意为“是不是”，从句中该用甚么时态就利用甚么时态。
if指导前提状语从句时意为“假设”，从句中利用一般如今时取代一般未来时。
e.g.She wanted to know if you were a teacher.
I don’t know if the letter is yours.
They’ll go boating if it is fine tomorrow.
I’ll give it to her if she comes next week.
(2)if指导宾语从句时大都环境下可以与whether交换，但若要凸起“到底是……仍是不……”这层意思时，通经常使用whether，并在后面的加之“or not”，即一般要选择whether组成whether…or not的布局。
e.g.Please find out whether the money is his or not.
Let me know whether you can come or not.
I want to know whether you can help me or not.
