Unit 2 I think that mooncakes are delicious！语法精讲 （一）宾语从句宾语从句是英语复合句中的其中非常重要的从句之一。在复合句中做宾语成分的句子叫做宾语从句。(一)  宾语从句的语序宾语从句中，无论主句是陈述句还是疑问句，宾语从句都要用陈述句语序，即“主语在前，谓语在后”的顺序。(连接词 + 主语 + 谓语 + 其他)Do you know where he lives? (√)Do you know where does he live? (×)He asked me whether she was a teacher. (√)He asked me whether was she a teacher. (×) (二)  宾语从句的时态宾语从句的时态受主句的限制。主句的谓语动词是一般现在时或一般将来时，其宾语从句可以为任何适当的时态。I don’t know that Tom has been here for two days.I will take back what I said.I’m sorry that I will trouble you.主句的谓语动词是一般过去时，其宾语从句用相应的过去时态(过去完成时、一般过去时、过去进行时、过去将来时)。Tom told me that Peter had gone to the airport.I heard that he would give us a talk.I was pleased that my father helped these people.如果宾语从句说的是客观真理、自然现象或事实时，这时无论主句是什么时态，宾语从句要用一般现在时。Our teacher said that January is the first month of the year.The teacher said that the earth goes round the sun.He told me that Japan is an island country.Our teacher told us that light travels faster than sound.(三)  宾语从句的连接词 类别用法说明示例连词thatThat引导的宾语从句是由陈述句转化而来，主句的谓语动词多是think/believe/guess/know/say/hope等，在口语中常可以省略。He said that he wanted to stay at home.I told him that he was wrong.I believe that you have done your best.I am sure that he will succeed.连接词if, whetherwhether, if在宾语从句中不做句子的成分，两者含义没有区别，都译为“是否”。一般情况下，whether和if 可以替换。I don’t know if/whether he will come tomorrow.The teacher asked if/whether we had finished the experiment.只能用whether不能用if宾语从句中有or not时I don’t know whether the movie star will come or not.在介词后面的宾语从句Everything depends on whether we have enough money.We are talking about whether we will go there tomorrow.和不定式连用作宾语时They asked me whether to go skating. We haven’t decided whether to visit there tomorrow.宾语从句置于居首时Whether they will attend the meeting, I don’t care.连接代词连接代词who, whom, whose, what, which引导宾语从句时，这些词本身具有实际意义，并且在从句中作一定的句子成分(主语、宾语、定语等)。Do you know whom they are playing with?He asked me whose English was the best in our class.He asked who could do it by himself.Do you know what they are doing here.Do you know which film they are talking about?连接副词连接副词when, where, why, how引导宾语从句，这些词本身具有实际意义，并且在从句中作状语。(when-时间状语/where-地点状语/how-方式状语/why-原因状语)Can you tell me where the nearest supermarket is?Do you know when the train leaves?I wonder how he can learn English so well.Could you please explain why you were late for school. (四)  宾语从句的否定转移用法说明示例当主句的谓语动词是think, believe, suppose, expect, guess, imagine等表示“认为，猜想”的词时，一般要把宾语从句中的否定式转移到主句中。I believe he will come here on time.(改为否定句) I don’t believe he will come here on time.(√)I believe he won’t come here on time.(×)  练习：I think that you are the owner of the house.(改为否定句)____________________________________.答案：I don’t think you are the owner of the house.(五)  宾语从句的简化 用法说明示例当宾语从句的主语和主句相同，且主句的谓语动词为agree, decide, hope, wish 等时，从句可以简化成不定式。We have decided that we will go there by air.=We have decided to go there by air.I hope that I will hear from you soon.=I hope to hear from you soon.当宾语从句的主语和主句的主语相同时，且主句的谓语动词为forget, know, learn, remember等时，从句可以简化为“疑问词＋不定式”。I forget which bus I should take.=I forget which bus to take.   (乐山中考)——Hello, this is Dick.
