Whatever has happened before or is happening now是一个主语从句,whatever既引导起这个主语从句,也在句中做主语。

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。

高一名词性从句练习20题含答案解析
高一英语名词性从句练习题20题含答案解析1._____ is known to all, the earth moves around the sun.A.WhatB.AsC.WhichD.That答案解析:B。
本题考查定语从句与主语从句的辨析。
“As is known to all”是固定用法,意为“众所周知”,as 在句中引导非限制性定语从句,指代后面整个句子“the earth moves around the sun”。
A 选项“What is known to all”没有这样的用法;C 选项“Which”引导定语从句时,前面一般有先行词,此处没有;D 选项“That”引导主语从句时,不在句首这种位置,一般放在句中。
2._____ he will come or not is still a question.A.WhetherB.IfC.ThatD.What答案解析:A。
“Whether...or not”是固定搭配,表示“是否”。
B 选项“If”也有“是否”的意思,但不能与“or not”连用;C 选项“That”引导主语从句时无“是否”之意;D 选项“What”引导主语从句时意思不对。
3.I don't know _____ he will come tomorrow.A.thatB.ifC.whenD.what答案解析:B。
A 选项“that”在宾语从句中无实际意义,此处不符合;C 选项“when”表示时间,题干中没有时间提示;D 选项“what”在宾语从句中要充当成分,此处不需要。
B 选项“if”表示“是否”,符合题意。

13.--- made her ashamed of herself?--- the lowest mark in her class.A. What; Because she gotB. Was it what; GettingC. What was it that; That she gotD. What was it that; Get【答案】 C【解析】【分析】句意:——是什么让她对她自己感到羞愧?——是她获得了她班上的最低分让她惭愧。
A中的what是句子的主语,但是because引导的从句不作主语,是原因状语从句,故排除;B的第一空是错误形式,故排除;C、D两项的第一个选项是一样的,说明第一个题干是一个强调句型,特殊疑问句下的强调句型,有what引导;第二个空是对what的回答,因为what是上一句的主语,That she got the lowest mark in her class是从句,可以作主语;而D项的get是动词原形,不能作主语,故答案为C。
【点评】考查强调句型的使用和对特殊疑问句的回答,注意问什么回答什么,也就是说疑问词what是句子的主语,回答的内容也需要在句子中能作主语。
14.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。
