2、是以直线传播的。 It so happens that I know the man. 碰巧我认识那个。 Is it certain that they will win 他们一定会赢吗Bwhether和if 连词whether和if本身有意义（解释是否），在从句中不可省略。 1whether可以连接所有的名词性从句，而if只能引导宾语从句。 I didnt know whether he would attend the concert. 我并不知道他是否参加音乐会。（宾语从句，可用if代替whether） The question is whether it s worth trying.

4、是否支持我们。(不用if) Ryan was worrying about whether he had hurt her feelings. 瑞恩担心是否伤害了她的感情。 3if既可引导语从句，也可引导宾语从句。如果用if会引起歧义，应避免使用if，而用whether。 Please let me know if you want to join us. 请告诉我你是否想加入我们。（if引导的从句可被看成是宾语从句，if表示是否） Please let me know if you want to join us. 如果你想加入我们的话，请告诉我一声。（if引导的从句可被看成是条件状语从句，
5、if表示如果） Please let me know whether you want t join us. 请告诉我你是否想加入我们。（为避免引起歧义，可用whether表示是否）Cwho, whom, whose, what, which 连接代词who, whom, whose, what, which等在从句中既起连接作用，同时又担当主语、宾语、定语、表语等成分。 No one knows who he was waiting for. 没人知道他当时在等谁。 We are worrying about what we should do next. 我们正在为下一步该怎么办而烦恼。

8、ver 连接代词whoever = anyone who任何人, 无论谁；whatever =anything that凡是.，无论什么；whichever = anything that无论那一个, 任何一个；whomever = anyone whom （whoever的宾格形式）。 Whoever comes to the club is welcome. 不论谁来参加这个俱乐部都欢迎。 Whatever is worth doing at all is worth doing well.凡是值得做的就值得做好。 They ate whatever they could find o t

10、，因为whoever在宾语从句中作wants it的主语） You may offer the book to whomever you like.你可把这本书给任何你喜欢的人。（whomever在宾语从句中作you like的宾语）二、宾语从句在复合句中用作动词宾语或介词宾语的从句叫宾语从句。A. 作动词宾语 He told us（that）he felt ill. 他对我们说他感到不舒服。 Do you know whose dictionary it is 你知道这是谁的字典？ He has informed me when they are to discuss the work pl

15、not come yesterday. 我们认为小王昨天没来是奇怪的。 He has made it clear that he will not give n. 他已表明他不会屈服。 2由于that引导的宾语从句一般不可以直接作介词的宾语，因此当介词后面需要用that从句作宾语时，必须使用it作形式宾语。 You may depend on it that I shall always support you. 你可以放心我会永远支持你的。 Ill see to it that your problem will be dealt with immediately. 我保证你的问题会立即得到处理的。 3在take, hide, see to, insit on, depend on等动词以及一些表示爱好的动词（enjoy, hate, like, love, dont mind, resent 等）之后，形式宾语it可直接跟宾语从句。 I take it that hes not interested in the book. 我猜想他对这本书不感兴趣。 She hid it that she was married. 她隐瞒
