Summary 宾语从句 1. 定义：在句子中起宾语作用的从句叫做宾语从句。 引导宾语从句的常见关联词有that, if, whether, what, where, why, how等。 2. 三要素：①引导词(连接词): that, if, whether ②时态：当主句用一般过去时时态时，宾语从句 要用过去的某种时态。 ③语序：宾语从句用陈述句语序，即 “主语+谓语”。 e.g. He asked me where my school was. I didn’t know who she was 学习总结 学习目标 学习过程 Summary that,if和whether引导的宾语从句 1. 由that引导的宾语从句：当宾语从句具有陈述意义时，用 that引导。that 在句中无词汇意义，在从句中不充当成分，在口语当中往往省略。 e.g. I think (that) math is difficult. She said (that) she would leave a note on the desk. 【注意】连词that不能省略的几种情况： ①1. 从句的主语是that。 e.g. He says that that is a real king’s hat. ②that从句中含有主从复合句。 e.g.I’m afraid that if you’ve lost it, you must pay for it. ③主、从句之间有插入语时。 e.g.It says here, on this card, that it was used in plays. ④若出现两个或两上以上的由that引导的宾语从句，且由 并列连词连接时，只有第一个连词that可以省略。 She said (that) she would come and that she would also bring her son. 学习总结 学习目标 学习过程 Summary that,if和whether引导的宾语从句 2.由if / whether引导的宾语从句：当宾语从句具有疑问意义时，可用if或whether引导。它们在句子中的意思是是否, 不能省略。 ① if和whether引导宾语从句时，作“是否”讲，一般情况下，二者 没有区别，可以换用。但if常用于口语中，whether比较正式。 e.g. Millie asked if/whether he liked this sweater. ② 由于if和whether连接的是一般疑问句，因此要注意把从句语序 改为陈述句语序。 e.g.Does Mr Zhao live in Room 208? Could you tell me? →Could you tell me if/whether Mr Zhao lives in Room 208? ③ if和whether的区别（二者在下列几种情况下不能换用）： 1. 宾语从句置于句首表示强调时，应用whether，不用if。 e.g. Whether this is true or not, I can’t say. 2. 宾语从句与or not直接连用时，应用whether，不能用if。 e.g. I don’t know whether or not he will come tomorrow. 3. 与动词不定式连用时，只能用whether。 e.g. She can’t decide whether to go to America. 4. 从句作介词宾语时，只能用whether。 e.g. I worry about whether I hurt her feeling. 5. 宾语从句的谓语动词是否定形式时，只能用if，不能用whether。 e.g. Tom wants to know if she won’t come here tomorrow. 6. if意为“假如，如果”时，可以引导条件状语从句，而whether没有这个用法。 e.g. If Simon comes here tomorrow, I’ll call you. 学习总结 学习目标 学习过程 Summary 宾语从句的时态变化 宾语从句的时态一般受主句时态的影响。当主句是一般现在时或一般将来时，宾语从句可以根据具体情况用适当的时态；当主句是一般过去时，从句要用相应的过去时。 主句时态 从句时态 一般现在时、一般将来时、祈使句时 根据句意的需要用任意一种时态 一般过去时 与原句相对应的过去的时态 客观事实、真理、自然现象、名言警句、谚语等 一律用一般现在时 宾语从句歌： 学习宾从三注意，时态语序和连词。时态主从要呼应： 主句若为现在时，从句时态随句意；主句若为过去时，从句时态变过去； 宾从若是表真理，时态不变无质疑。语序要用陈述序，切莫照搬疑问句。 That 连接陈述句，省与不省要注意。从句若表“是否”时,if/whether要慎记。 特殊问句作宾语，仍用原来疑问词。三个问题需牢记，切莫丢东忘了西。 学习总结 学习目标 学习过程 Have a try! 用所给动词的正确形式填空。 I hope he _________ (come) back in a week.  Our teacher told us that light_______ (travel) much faster than sound.

How delicious the food is in Hong Kong! 感叹句 用来表达喜、怒、哀、乐等强烈感情的句子叫感叹句。感叹句一般用what或how引导，句末用感叹号。what修饰名词，how修饰形容词或副词。 Grammar what引导的感叹句 What an honest man (he is)! What beautiful flowers (these are)! What bad weather (it is)! how引导的感叹句 How good a book it is! How careless (you are)! How+ adj.+ a/an+ n.+主+谓+…! How+(adj./adv.)+主+谓+…! What+ a/an+(adj.)+n.(单数)+(主+谓)+…!

One is Mother’s Day on the second Sunday of May, and the other is Father’s Day on the third Sunday of June. On these two days, American children often give gifts to their parents or take them out for lunch or dinner. Common gifts are flowers and cards for mothers and shirts or ties for fathers. I heard that it is becoming more and more popular to celebrate Mother’s Day and Father’s Day in China. I wonder if children over there also give similar gifts to their parents. I believe that there are many ways to show our love. Actually, we don’t have to spend a lot of money. It is also a good idea to help parents to do something instead. June 1.
