语法宾语从句
一、基本讲解
1 概念:在句中担当宾语的从句叫宾语从句，宾语从句可作谓语动词的宾语，也可做介词的宾语。

eg, 1.He said he was good at drawing. 2.He asks him how long Mike has been down .
2.连接词
(1) .陈述句转化成宾语从句时，引导词用that,口语中常常省略。

eg, She told me (that) she would like to go with us.
(2)以 whether 或 if 引导的宾语从句, 主要用来引导一般疑问句意思或选择疑问句意思的宾语从句，从句同样是陈述语序eg, I wonder if /whether you have told the new to Li Lei .
(3).特殊疑问句转化成宾语从句时，引导词用特殊疑问词；引导词后要用陈述句语序。

E.g. Could you tell me what's the matter\wrong with you?
特殊情况：：当do you think后接特殊疑问句转化成宾语从句时，句式结构应为引导词＋do you think＋陈述句语序。

3.宾语从句时态
a.当主句是一般现在时，一般将来时或祈使句时，从句不受主句的限制，根据自身的需要选用相应的时态。

例如：Do you know（if/whether he has seen the film）?
b.当主句是一般过去时，从句要用过去时的相应时态。

例如：
I didn't know （if/whether he had seen the film.）
注意：当主句是一般过去时，而从句表示的是客观真理，自然现象，科学原理，格言等，从句仍然要用一般现在时。

例如：
He said （that the earth moves round the sun.）
The teacher told us （that light travels much faster than sound.）
4.、人称的变化和标点的使用
a.从句的主语如果是第一人称，变为宾语从句则与主句的主语一致；如果是第二人称，则与主句的宾语一致；如果是第三人称，不用变化。

如：
“May I use your knife？”He asked me. →He asked me if he might use my knife.
b.宾语从句的标点均由主句决定。

主句是陈述句，用句号；主句是疑问句，用问号。

如：
Do you know？Where does he live? →Do you know where he lives?
二、宾语从句的转化
1.当主句谓语动词是hope，wish，decide，forget，plan，agree等，且主句主语与从句主语相同时，从句可简化为不定式结构。

如：
She agreed that she could help me with my maths. →She agr eed to help me with my maths.
2.当主句的谓语动词是know, learn, forget, remember, decide等后面带特殊疑问句转化的宾语时，主从句的主语也须一致这时从句可以简化成“疑问词＋不定式结构”。

例如：
I don't know which sweaterI shouldbuy.→I don't know which sweater to buy.
3.当主句的谓语动词是ask，tell, show, teach等后面带双宾语时，从句的主语和间接宾语一致，且从句是由特殊疑问句转化来时，从句可以转化成“疑问词＋不定式结构”,或者在连接代词/副词引导的宾语从句中，当从句主语与主句主语或间接宾语一致时，宾语从句
可简化为“连接代词/副词＋不定式”结构。

如：→Could you tell me how to get to the park?
4. 当主句谓语动词是find，see，watch，hear等感官动词时，从句常简化为“宾语＋宾补”结构，宾补为不带to的不定式或V-ing形式。

如：She found that the wallet lay/was lying on the ground.→She found the wallet lie/lying on the ground.
