宾语从句讲解以及while的用法.docVIP

宾语从句讲解在复合句中用作宾语的从句叫宾语从句。’t take part in the sport meeting next Sunday. 补充 在主句为动词be加某些形容词（如sorry，sure，afraid，glad等）作表语时，后面所跟的省略that的从句也是宾语从句 I’m sorry（that）I don’t know. We’re sure （that） our team will win. I’m afraid （that）he won’t pass the exam. 2.当宾语从句是一般疑问句时，由连词whether或if 引导,表示“是否”，具有一定的含义，所以不能省略。 Let’s see if/whether we can find out some information about that city. She asked me if/whether she could borrow these books. Lily wanted to know if/whether her grandma liked the handbag. 3.当宾语是特殊疑问句时，由连接代词（what，who，whom， which， whose）或连接副词（when，where， how，why）引导，在从句中担任一定句子的成分，具有一定的意义，所以不可以省略。 Do you know what he said just now? I don’t remember when we arrived. I asked him where I could get so much money. Please tell me who(whom) we have to see. Do you know what time the plane leaves? 补充 带how的词组也都可以引导宾语从句 How much；how often；how long；how far；how many；how old；how soon 练习 1.The young man asked ___________ it’s summer or winter.
