The Object Clause———— 宾语从句 一：基本定义在主句中用一个句子来代替宾语的位置，该从句叫宾语从句。二：宾语从句的引导词：1. That : 引导陈述句，无意义，可以省略。I know (that) he is a teacher.I hear (that) he will come back in a month.He told us (that) he was going to Beijing. 2.If / whether: 引导一般疑问句，表是否。I don’t know. Is he our new teacher? = I don’t know if/whether he is our new teacher.She wondered( 疑惑 ) if/whether it rained last night.I am not sure if / whether he will come tonight.3. 特殊疑问词：引导特殊疑问句。The teacher doesn’t know why he comes late.Let me show you how it works.He asked the policeman which is the way to the school.Can you tell me who is the headteacher? 三：宾语从句的语序：宾语从句用陈述语序：主句 + 连接词 + 主语 + 谓语。。。陈述句——基本不变疑问句——还原为正常语序1) 情态动词、 be 动词及助动词 have 放到从句主语之后2) 助动词 do ( does 、 did ) 应删去。 1 My father will be back soon.I know that 2 Who is Jim waiting for ?I know who 3 Can Lily carry the basket ?I know whether/if 4 What time will the train leave ?I know what timemy father will be back soon.Jim is waiting for.Lily can carry the basket.the train will leave. 四：宾语从句的时态：1 。当主句是一般现在时，宾语从句根据实际来判断。 he will ask Jim a questionHe says I am a good friend. he isn’t feeling well now. he came back last night.2 。当主句是一般过去时，宾语从句应用过去的某个时态（一般过去时，过去进行时，过去将来时）He told me he would leave Chongqing soon.He wanted to know what they were talking about.I believed that no one was right. 四：宾语从句的变化步骤：1. 确定引导词——根据原句的类型2. 调整语序3. 变化时态——看主句五：宾语从句的几个注意点。* If 和 whether 的区别。1 。 Whether 后能跟 or not, if 不行。I’d like to know whether he will come or not.2. Whether 后能加 to do, if 不行。He doesn’t know whether to work or play.3. 在介词后只能用 whether 不能用 if.He is trying to find out whether the medicine works * 如果宾语从句表示的是客观真理，那么不管主句是什么时态，宾语从句都用一般现在时。The teacher told us yesterday that the moon travels round the earth once every day.I was sure that light travels at a speed of 300,000 kilometers per second.
