一、初中英语名词性从句

A. What; what B. That; that C. What; that D. That; what 【答案】 C
【解析】【分析】句意：让我感到担忧的是，今天的歌星是以青少年为中心的。分析句子可知，主语从句中的谓语动词makes 缺少主语，主语从句中缺少宾语一般用what，因此选择 what 来引导主语从句；系动词 is 后面的表语从句句意完整，不缺少成分，因此选择 that 引导表语从句。分析选项可知C项符合题意，故选C。
【点评】考查名词性从句，本题涉及 what引导的主语从句和that引导的表语从句的应用。

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。
