A. when are the planes to take off B. that are the planes to take off C. where are the planes to take off D. when the planes are to take off 【答案】 D 【解析】【分析】句意: 飞机什么时候起飞已经宣布了吗？此处是when引导的主语从句，且要用陈述句语序，故选D。 【点评】考查名词性从句，it作形式主语，关系副词when引导的从句作真正的主语。 3．In the past decade, our education system too much on grades. However, grades have a direct connection with future success is still a question. A. focused; whether B. focused; if C. has focused; whether D. has focused; if 【答案】 C 【解析】【分析】考查时态和主语从句。根据In the past decade,在最近的几十年里，可知句子用现在完成时态，our education system是句子的主语，单数形式，所以第一空填has focused；第二空是主语从句做主语，if是否，不能引导主语从句，所以第二空填whether。故选C。 【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。 3）用连接副词when, where, why, how引导的名词性从句（其连接副词有含义,在句中作状语。）例如：Where we should leave it is a problem.
