【点评】主语从句主要有三类：
1）（1）由连词that引导的主语从句:引导词that无含义,在句中不做成分,不可以省。例如：That you will win the medal seems unlikely.你想获得奖牌看起来是不可能的。（2）用连词 whether 引导的主语从句:whether有含义（是否）,在句中不做成分,不可以省。例如：Whether she is coming or not doesn't matter too much.她来不来都无关紧要。注意：if不能引导主语从句。
2）用连接代词引导的主语从句（在由连接代词who, whose, whom, which, what, whoever, whomever, whichever, whatever引导的名词性从句中，其连接代词在句中起名词性作用，担当一定成分）.例如：What you need is more practice.你所需要的是更多的训练。
