She says (that) she wont take part in the sports meetingnext Sunday. Jim thought (that) the train was like a big moving party. He said (that) he would like to see the headmaster.,在主句为动词be加某些形容词（如sorry, sure, afraid, glad等）作表语时，后面所跟的省略that的从句也可算是宾语从句,Im sorry (that) I dont know . Were sure (that) our team will win . Im afraid (that) he wont pass the exam .,2. 当宾语从句是一般疑问句时，由连词whether或if引导（口语中常用if），因为if/whether翻译成：“是否”，具有一定的意义，所以不能省略,Lily wanted to know if /whether her grandmaliked the handbag .

I know he lived here ten years ago . I have heard that he will come tomorrow .,2.如果主句是过去的时态（包括一般过去时，过去进行时），那么从句的时态一定要用相对应的过去的某种时态（包括一般过去时，过去进行时，过去将来时， 过去完成时）,I knew who lived here.

He said that he had seen it .,3.当从句是客观真理，定义，公理，定理时用一般现在时。,The teacher said that the sun travelsaround the earth .,三、语序 宾语从句的语序用陈述语序： 连接词+主语+谓语+其他成分,1. When will he go to the library?
