Being the sun and not the earthD. That the sun and not the earth【答案】 D【解析】【分析】句意:太阳而不是地球是我们行星系统的中心,这在中世纪是一个很难理解的概念。
分析句子可知,整个句子为主系表结构,was为系动词,它之前的都为主语,且主语由句子来充当,句子结构以及句意完整,所以连词代词为that。
故选D。
【点评】考查名词性从句,本题涉及that引导的主语从句。
2._____ is known to us all is that China has launched Shenzhou VII spaceship, ____ made the country's first spacewalk successful.A. That; whatB. What; whichC. It; whichD. As; that【答案】 B【解析】【分析】句意:众所周知,中国已经发射了神州7号宇宙飞船,这是中国首次成功的太空行走。
第一空处为主语从句,从句缺少主语,需用what引导;第二空所在句子是个定语从句,先行词为整个主句的内容,从句中缺少主语,需用which引导。
故选B。
【点评】考查名词性从句和定语从句,本题涉及主语从句和非限制性定语从句的应用。
3.While some behaviors may seem strange to you, remember you consider normal probably seems just as unusual to others.A. it; thatB. what; thatC. that; whatD. which; that【答案】 C【解析】【分析】句意:虽然有些行为对你来说可能很奇怪,但请记住,你认为正常的行为对别人来说可能也不寻常。
第一空为宾语从句,从句结构完整用that起连接作用,第二空为主语从句,从句中consider缺少宾语,应该用what,故选C。
【点评】考查名词性从句,本题涉及that引导的宾语从句和what引导的主语从句。
4.___ surprised me most was ____the girl passed the driver test.A. That; thatB. What; howC. What; thatD. That; why【答案】 C【解析】【分析】句意:最让我吃惊的是那个女孩通过了驾驶考试。
___ surprised me most是一个主语从句,从句中缺少主语,故填what;____the girl passed the driver test 是一个表语从句,句中不缺少成分,故填that。
因此选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。
5.Some people believe _______ has happened before or is happening now will repeat itself in the future.A. whateverB. wheneverC. whereverD. no matter what【答案】 A【解析】【分析】句意:一些人认为之前发生的或现在正在发生的任何事情在将来都会重复发生。
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。
BC项都属于副词的性质,都不能做主语,通常只能做状语;no matter what只能用来引导状语从句,故选A。
【点评】考查名词性从句,本题涉及"特殊疑问词+ever"引导的主语从句。
6.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.7.____ he will offer us enough help doesn't matter a lot to our success.A. IfB. WhetherC. BeforeD. How【答案】 B【解析】【分析】句意:他是否提供帮助对于我们的成功没有什么关系。
If不可以引导主语从句,故选B。
【点评】考查名词性从句,本题涉及whether引导的主语从句的应用。
8.____ 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。
第一空填what,它一方面在句子中引导主语从句,另一方面又在主语从句中作主语;第二空用that引导表语从句且从句中不缺成分,表示对前面情况的说明。
故选A。
【点评】考查了名词性从句,本题涉及what引导的主语从句以及that引导的表语从句。
9.It is a rule in his family that _______ comes home first should cook the dinner.A. anybodyB. whoC. whoeverD. who that【答案】 C【解析】【分析】句意:在他的家里有个规定,就是先到家的人要先做饭。
whoever 有两个词义:1no matter who,在这种用法时引导一个让步状语从句;2anybody that,在这种用法时,它连接一个名词性从句,在本题中它连接的是主语从句。
这里就是第二个用法。
所以选C。
10.________ the weather will not clear up until next week is bad news for us.A. AsB. IfC. WhetherD. That【答案】 D【解析】【分析】考查主语从句。
句意:直到下周天气才放晴,这对我们来说是坏消息。
此处是that引导的主语从句,that无实义,只其引导作用,故答案为D。
【点评】主语从句属于名词性从句,在名词性从句中,that无实义,只起连接作用,不做句子成分;if/whether起连接作用,不做句子成分,有实义“是否”。
做题时注意看从句是否少成分。
11.______ amazed the NBA world is ______ Kobe Bryant scored 81 points just in one game.A. That, whatB. What, thatC. That, thatD. What, what【答案】 B【解析】【分析】句意:使NBA世界惊讶的是Kobe Bryant在一场比赛中得了81分。
根据句意可知,句子主语是一个主语从句,引导词即起引导作用又要做从句的一个成分,所以第一空填What;第二空是that引导的表语从句,只起引导作用,故选B。
【点评】考查名词性从句,本题涉及关系代词what引导的主语从句和表语从句的应用。
12.________ we may find interesting is that it usually takes more to be polite.A. ThatB. WhatC. WhichD. /【答案】 B【解析】【分析】句意:我们可能会发现有趣的是通常需要更多的礼貌。
