She doesnt know (that) she is seriously ill. I am sure (that) he will succeed. 2. 由连接代词 who, whom, whose, what, which 和连接副词 when, where, why, how 引导的宾语从句。这些连接代词和连接副词在宾语从句中充当某个成分。例如： Do you know who (whom) they are waiting foe? He asked whose handwriting was the best. Can you tell me where the No.3 bus stop is? I dont know why the train is late. 3. 由 if 或 whether 引导的宾语从句。If 和 whether 在句中的意思是"是否'。例如： I want to know if (whether) he lives there. He asked me whether (if) I could help him. 二. 宾语从句的语序 宾语从句的语序应为陈述句的语序。例如： I hear (that) physics isnt easy. I think (that) you will like this school soon. Can you tell me how I can get to zoo? Please tell me when well have the meeting. 三. 宾语从句的时态 1. 假设主句的时态是一般如今时，宾语从句该用什麽时态就用什麽时态。 如： I dont think (that) you are right. Please tell us where he is. Can you tell me how I can get to the railway station? 2. 假设主句的时态是一般过去时，宾语从句只能用相应的过去时态〔一般过去时，过去进展时，过去将来时，过去完成时〕。例如： He asked what time it was. He told me that he was preparing for the sports meet. He asked if you had written to Peter. He said that he would go back to the U.S. soon. 第 8 页精品文档---下载后可任意编辑 3. 假设宾...
