Whether可以引导表语从句和同位语从句，if不可以。4).用在动词不定式之前时用whether不用if。► I don’t know whether to go there at once. 我不知道是不是该立刻去那里。3.由连接代词 who, whom, whose, which, what 和连接副词 where, how, why, when引导的宾语从句►Do you know whose book it is ?►Please tell me when we’ll have a meeting .►Could you tell me why the train is late?►He asked who could answer the question.宾语从句的语序无论主句是陈述句还是疑问句，宾语从句都是运用陈述句的语序，即是“主语在前，谓语在后”的顺序。►Danny says that he will learn English. ►Do you know where he came from? ►Please tell me how I can get to the bus station .What 和 How引导的感叹句所谓感叹句，就是用来表达喜怒哀乐等强烈情感的句子。近年来，感叹句的构成及转换是中考常考的考点之一。感叹句一般由“what”和“how”来开头的句子 “what”修饰名词，“how”修饰形容词和副词。What 引导的感叹句“what”意为“多么”用作定语，修饰名词（被强调部分），名词前可有其它定语成份（即：形容词或冠词）。单数可数名词前要加不定冠词a/an，复数可数名词或不可数名词前不用冠词。一般有三种形式，此时what为形容词，作定语，用来修饰它后面的名词或词组。1. what+a/an+形容词+可数名词单数+主语+谓语！►What an interesting story it is! 多么有趣的故事呀！►What a good girl she is! 她是个多么好的一个女孩啊！2. what+形容词+不可数名词+主语+谓语！►What heavy snow it is! 多么大的雪呀！►What bad weather it is! 多么糟糕的天气！3. what+形容词+可数名词复数+主语+谓语!►What beautiful flowers they are! 多么漂亮的花啊！►What good students they are! 他们是多么好的学生啊！How 引导的感叹句“how”意为“多么”，用作状语，修饰形容词或副词（被强调部分）。如果修饰形容词，则句中的谓语动词用系动词；如果how修饰副词，则句中的谓语动词用行为动词。... ... ...关键词：I think that mooncakes are delicious!
