10、语从句的语序陈述语序，即“连接词+主语+谓语+其它成分”特别强调：它的主语和谓语的语序是陈述语序，而不是疑问句的倒装结构。Can you tell me who do we have to see?（）Can you tell me who we have to see?（ ）The teacher asked the students what they were doing. （ ）陈述句变为宾语从句时,要注意人称和时态的变化,语序不变。eg.

11、a message on the desk.一般疑问句和特殊疑问句变为宾语从句时,也要注意人称和时态的变化,后面接陈述语序。Eg. “Where are the tickets?” I asked him. I asked him where the tickets are.三、时态呼应。如果主句谓语是一般现在时或将来时，从句谓语的时态不受限制；如果主句谓语的时态是一般过去时，从句一般要随着改为相应的过去时态（一般过去时、过去进行时、过去将来时、过去完成时）eg. I thought （that） you are free today. （）I thought （that） you would

14、他的微笑表明他面试得很好。3. 动词wish 后的宾语从句也要用虚拟语气，即从句谓语用过去式（针对现在情况而言）、过去完成时（针对过去情况而言）或用“would / should / could / might +动词原形”（针对将来情况而言）。I wish I were a bird. 我希望我是一只鸟。I wish we lived on the moon now. 我希望我们现在住在月亮上。五、注意宾语从句的否定问题当否定宾语从句时，一般直接对从句的谓语动词进行否定。I know that he wont tell a lie to us. 我知道他不会对我们说谎。He said he

15、hadnt been to america before. 他说他以前没有去过美国。但是，当主句的谓语动词为think, believe, suppose, imagine等，若时态为一般现在时，谓语动词前又没有副词修饰时，宾语从句的否定应该转移到主句的谓语动词上。如：I dont think that he will come to help us today. 我想他今天不会来帮我们的忙了。表三： 表语从句定义在一个复合句中其表语部分是一个句子，这个当表语的句子就是表语从句。表语从句位于连系动词之后。连系动词1.be 动词2. 感官动词look“看起来像是” smell“闻起来” soun
