主语从句表语从句学案和专项练习

Subject Clause and Predicative ClauseⅠ. 主语从句(Subject Clause)一定义:__________________________________________________.1. He is right .2. What he said is right .二.主语从句引导词1.主语从句的引导词与宾语从句一样。

〔但不用if 〔是否〕,只能用whether(是否)〕1) that 2) whether3) what , which ,who, whom, whose, whatever , whichever.....4) where , when , why, how, wherever, whenever .....5) how many , what color, how far等。

2. 引导主语从句的关联词除起连接句子的作用,绝大多数关联词在主从中要充当一定的句子成分。

3. 主语从句的语序是:关联词+S+V三. 主语从句引导词的用法:1. that 的用法:that 引导句意完整, 意义明确不缺成分的述句;无词义,在主从中不充当句子成分,不能省略。

高中英语主语从句练习及答案

高中英语主语从句练习及答案

英语练习: 主语从句Ⅰ. 用适当的连接词填空1.They lost their way in the forest and ______made matters worse was ______nightbegan to fall.what, that and连接两个分句,and后面的分句中含有一个主语从句和一个表语从句;主语从句中缺主语,what made matters worse “使事情更糟糕的是…”,后面的night began to fall意义完整,作表语,不需要有意义的引导词,所以填that。

2. There is no doubt, in my opinion, that _________matters is not the quantity, but the quality of the products.There is no doubt that…. “毫无疑问…”,in my opinion 是插入语,that引导的是一个同位语从句。

that同位语从句中又含有一个主语从句:_____matters, matter 是谓语动词,指“有关系,要紧,重要”,其前无主语,所以填what。

3. It doesn’t interest me _______you succeed or not.It是形式主语,替代后面的主语从句。

由or not可知该空填whether。

4. _______the astronaut ate his food in space is _______we want to know.How, what(如果你懂得来龙去脉,可以不看下面的文字)一定要懂得句子作一个成分如主语或宾语时,一定有一个引导词+陈述句,而这个引导词的选择取决于意义和句子成分。

还有一点关键的,不少同学不会断句,根本不知道哪里是从句。

如果一眼看不出来,先找动词,动词要不前面有名词或代词,要不后面有名词或代词,如果是不及物动词,后面就没有宾语。

主语从句1. was needed at that time, she told me, was some good luck.A. ThatB. AsC. ItD. What【答案解析】 D【详解】考查主语从句。

句意:她告知我,在那时她所须要的东西是一些好运。

在这句话中she told me做插入语不影响句子结构,所以在其次个was之前是主语从句作句子主语。

在主语从句中缺“什么”作句子主语,所以我们用what引导主语从句。

故此题选D。

2. Anyone who wants to can call any timepiece a clock, but technically speaking, only _________ ones ring out the time actually deserve the name.A. whateverB. wheneverC. whicheverD. wherever【答案解析】 C【详解】考查名词性从句。

句意:任何人都可以把任何时钟叫做钟,但是技术上来说,只有那些报时的钟才配得上这个名字。

分析句子结构可知,空白处与其后的ones ring out the time一起作主语,须要一个连接词,其中考虑空白处作定语修饰主语ones,要用whichever 表示“无论哪个”。

在意义上大致相当于 the person or the thing that。

故选C项。

3. It is _______ he said _______ is very important to me.A. what; thatB. that; thatC. all that; whatD. which; that【答案解析】 A【详解】考查主语从句和强调句型。

句意:他说的话对我很重要。

该句是一个强调句型“It is/was +强调部分+that+其他”,被强调的部分是一个主语从句,主语从句的连接词既起引导作用又做主语从句谓语动词的宾语,由what充当。

Whether we will hold a party in the open air tomorrow depends on the weather.Whether she is coming or not doesn ’t matter too much.(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,担当必然成分.比方: What you need is more practice.Whatever we do is to serve the people.注: whatever / whoever 的功用whatever, whoever 在主语从句中不含疑问意义。
