在口语和非正式文体中that常被省略She said she missed us very much.她说她非常想念我们I think she is right.我认为她是对的（that被省略）2. what, who, whom, which 是一组连接代词，引导疑问意义的宾语从句Can you tell me what bread is made from?你能告诉我面包是由什么制造的吗？I can’t remember who has e to my office.我不记得谁来过我的办公室了Tom asked me whom/who they were talking about.汤姆问我他们在谈论谁I want to know which is better.我想知道哪一个更好些3. when, where, why, how 是一组连接副词，引导疑问意义的宾语从句I’ m not sure when he will be back.我不能肯定他何时回来I can’t tell you where he lives.我不能告诉你他住在哪儿We don’t know why he broke the window.我们不知道他为何打破窗户。
Would you please tell me how I can get to the nearest bus stop?4. whether, ifwhether与if引导选择意义的宾语从句，意思为“是否”I wonder whether/if she still lives here after so many years.不知道经过这么多年她是否还住在这里Have you found out whether/if he is in London?你弄清楚他是否在伦敦了吗？(三)宾语从句的时态要和主句相呼应1. 如果主句是现在时态，宾语从句可以是实际需要的任何时态I am wondering whether he has e or not.我不知道他是否已经来了现在完成时）Please tell me when we’ll have the meeting.请告诉我什么时候开会一般将来时）I don’t know who they are talking about.我不知道他们正在谈论谁现在进行时）I have heard the window was broken by John.我已经听说窗户是被约翰打破的。
2. 如果主句是过去的时态，宾语从句必须选用过去的某一时态He said he would kill her.他说他会杀了她过去将来时）She told us Lucy had returned home.她告诉我们露茜已经回家去了过去完成时）Mary was wondering who could answer the question.玛丽想知道谁能回答这一问题一般过去时）I didn’t tell them where you were having the meeting.我没有告诉他们你们正在哪儿开会过去进行时）3. 如果宾语从句表示的是科学真理、客观事实或格言警句等，从句一律用一般现在时Granny told me that the earth moves around the sun.奶奶告诉我地球围绕太阳转She said a friend in need is a friend indeed.她说患难朋友才是真正的朋友同步练习：一、每空填一词，改写下列句子，使句意不变1.
