一、内容纲要
二、内容简述
（一）定义分类
用来充当另一个句子的宾语的句子，叫作宾语从句。
常用来连接宾语从句的连接词主要分为三大类：that；特殊疑问词；whether/if。
（二）that引导的宾语从句
此时，that不在宾语从句中充当任何成分，所以在口语中常被省略。
如：
She feels that he is sure to succeed in the race.
I knew that Jack had already finished his work.
I'm afraid that I cannot attend the party tomorrow.
（三）特殊疑问词引导的宾语从句
what、which、who、whom、whose、when、where、why、how等特殊疑问词都可以用来连接宾语从句。如：
I was at a loss as to what I should do next.
Jim didn't know which way she had taken.
They want to know when we will set out for Shanghai.
She has told me how she managed to arrive home last night.
（四）whether/if引导的宾语从句
whether/if表示“是否”，如：
They wondered if she had passed the driving test.
He asked her whether she would visit him the next week.
（五）间接引语
当把直接引语转为间接引语时，需要注意人称、时态和连接词的变化。如：
直接引语：She said to me, 'I am playing tennis in the gym now.'
间接引语：She told me (that) she was playing tennis in the gym then.
再比如：
直接引语：She said to me, 'Have you repaired my watch?'
间接引语：She asked me if/whether I had repaired her watch.
再比如：
直接引语：She said to me, 'When will you move to my city?'
间接引语：She asked me when I would move to her city.
【注意】
有关间接引语的用法，我们将在后续的文章里分享，敬请关注。
（六）特殊情况
1、形式宾语it
当“主谓宾补”结构中的宾语比补语长时，往往会为了避免句子头重脚轻，而被放到补语后面，此时其原有的位置就会通过形式宾语it来填补。如：
He made it clear that he would never attend the race.
上句话里的he would never attend the race原本应该放在made后面，但因为其篇幅比补语clear更长，所以被放到句末，而其原有的位置则采用it来填补。
2、当用if会引起歧义时，则须使用whether。如：
Please tell me if you like the job.
上面的句子有两种可能的含义，即：
1）If you like the job, please tell me.
2) Please tell me if you like the job or not.
所以，如果是要表达第2）的含义，为了避免歧义，就要采用whether，即：
Please tell me whether you like the job.
3、宾语从句否定的转移
当主句的谓语动词是think、believe、suppose、consider、expect、guess等，并且主句的主语是第一人称而且为一般现在时时，从句的否定词一般要转移到主句上来，其反义疑问句一般与宾语从句一致。如：
I don't think that it's a good idea to go for a picnic on such a windy day, is it?
我认为在这样一个多风的日子去野餐不是个好主意，是吗？
We didn't expect that he would come here so early in the morning, would he?
我们原以为他不会这么早就来这的，是吗？
4、宾语从句中虚拟语气的用法
这类用法一般是指当主句的谓语动词是表建议、要求、命令等的动词（如suggest/order/require/advise等）时，宾语从句的谓语动词要采用“should+do”的虚拟语气用法，should可以省略。如：
He suggested that we (should) start early tomorrow.
The officer ordered that the soldiers (should) never give in to the enemy.
