2.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; whetherB. focused; ifC. has focused; whetherD. 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.3.____ made me more unhappy was ___ the boy asked my friend to be his girlfriend and she agreed.A. What; thatB. That ; thatC. What; whetherD. It; that【答案】 A【解析】【分析】句意:让我更不高兴的是那个男孩要求我的朋友做他的女友,她同意了。
