7、 that is a real kings hat. 他说那是一个真的王冠。,2. that从句中含有主从复合句。如： Im afraid that if youve lost it, you must pay for it. 3. 主、从句之间有插入语时。如： It says here, on this card, that it was used in plays. 卡片上写着，它是古代演戏用的。,4. 若出现两个或两上以上的由that引导的宾语从句，且由并列连词连接时，只有第一个连词that可以省略。如： She said (that) she would come and that s

9、 if和whether引导宾语从句时，要注意宾语从句三要素，即连词、语序和时态。由于if和whether连接的是一般疑问句，因此要注意把从句语序改为陈述句语序。如： Does Mr Zhao live in Room 208? Could you tell me? Could you tell me if/whether Mr Zhao lives in Room 208?,其次要注意时态变化： 1. 若主句是一般现在时，从句用任何所需时态。如： He wants to know if / whether they had a good journey home. 他想知道他们回家旅途是否愉快

10、。,2. 若主句是一般过去时，从句则用跟过去相关的时态。即一般现在时变为一般过去时、现在进行时变为过去进行时、一般将来时为过去将来时、现在完成时态变为过去完成时。一般过去时变为过去完成时如： Did the train leave? She didnt know. She didnt know if / whether the train had left.,5. 宾语从句的谓语动词是否定形式时，只能用if，不能用whether。如： Tom wants to know if he wont come here tomorrow. 汤姆想知道他明天是否不来这儿。 6. if意为“假如，如果”时

11、，可以引导条件状语从句，而whether没有这个用法。如： If Simon comes here tomorrow, Ill call you. 假如西蒙明天来这儿，我将打电话告诉你。,主句使用现在时，从句可使用任何时态；主句使用一般过去时，从句除表示“真理”可使用现在时态外，一律使用过去相关的时态。,I think that you are right.,Lin Tao thought the TV play was very boring.,My brother told me that the earth is round.,宾语从句的时态取决于主句的时态,Write sentence
