语法精讲
一、主语从句的连接词
(1)从属连词:that,whether,if
(2)连接代词:who,whose,whom,which,what,whoever,whomever,whichever,whatever
(3)连接副词:when,where,why,how,whenever,however,wherever
二、主语从句的用法
1.that引导的主语从句
(1)that 只起连接作用,本身无意义,不充当任何成分,但不能省略。
That the factory will employ more new workers is true.
那家工厂将雇用更多的新工人是真的。
(2)that引导的主语从句作主语时,为避免头重脚轻,使句子平衡,常用it作形式主语,而将that引导的真正的主语从句后置,that不能省略。常见的此类句型有:
①It+be+形容词(important,necessary,clear,certain,natural,strange,obvious,likely,impossible,
possible...)+that从句。
It is necessary that we should learn English.
我们应学习英语是有必要的。
It is obvious that the accident was caused by drunk driving.
很明显,这起事故是由酒后驾车引起的。
②It+be+名词短语(no wonder,a pity,a shame,an honor...)+that从句。
It is a pity that you missed such a good chance.
真可惜你错过了一个这么好的机会。
③It+be+过去分词(said,believed,reported,thought,expected,decided,ordered,suggested...)+that从句。
It is known to all that Taiwan is part of China.
众所周知台湾是中国的一部分。
【名师点睛】
过去分词是suggested,advised,ordered,requested,required等表示建议、要求、命令等的词语时,从句要用虚拟语气,即从句的谓语用“should+动词原形”的形式,should可以省略。
④It+动词(短语)(seem,appear,happen,matter,turn out,prove,occur to...)+that从句。
It happened that he had to attend a meeting.
碰巧他得去参加一个会议。
2.whether/if引导的主语从句
whether/if尽管不充当句子成分,但是含有“是否”的意思,可以加上“or not”,其语意不变。若主语从句位于句首或和or not 连用时,则必须用连接词whether,而不用 if。
Whether they’ll set out at 7:00 tomorrow morning is unknown.
不知道明天早上他们是否要在7点出发。
【名师点睛】
引导主语从句时只有用it作形式主语时,whether和if都能引导主语从句。
It hasn’t been decided whether/if we shall attend the meeting.
我们是否去参加会议还没有决定。
3.连接代词引导的主语从句
连接代词what,who,whom,whose,which,whatever,whoever,whichever等在从句中作主语、宾语、表语、定语,不可以省略。
What we need now is more rest.
我们现在所需要的是更多的休息。
Every year,whoever makes the most beautiful kite will win a prize in the Kite Festival.
每年,谁做的风筝最漂亮,谁就能在风筝节上获奖。
Which football team will win the match is unknown.
哪一支足球队会赢得比赛还不清楚。
4.连接副词引导的主语从句
连接副词when,where,why,how,whenever,however,wherever等在从句中作状语。
Why the boy distracts frequently in class is what his teacher wants to know.
老师想知道为什么那个男孩经常在课堂上分心。
When the delayed flight will take off depends much on the weather.
延误的航班何时起飞在很大程度上取决于天气。
三、主语从句中应注意的问题
1.从句要用陈述语序
Where we will have a picnic should be discussed.
我们应该讨论一下将在哪里野餐。
2.主谓一致
(1)主语从句作主语,谓语动词一般用单数;但 what 引导的从句作主语,代表复数概念(常可从表语上看出)时,谓语动词则常用复数形式。
What he wants most is staying with his family.
他最想要的是和家人在一起。
What the boy wants are those red apples.
那个男孩想要的是那些红苹果。
(2)如果由and连接两个或两个以上的主语从句作主语时,谓语动词用复数;由两个或多个连接词引导一个主语从句时,谓语动词用单数。
When the task can be finished and whether he can have a rest are unknown.
什么时候能完成任务,他是否能休息一下都是未知的。
3.主语从句中的虚拟语气
在下列情形中,主语从句的谓语动词用“should+动词原形”。
(1)It is suggested/requested/proposed/desired/required that...,主语从句中的谓语动词要用虚拟语气。如:
It is suggested that we (should) take the bus.
有人建议我们乘公共汽车。
(2)在用it作形式主语的时候,如果作表语的形容词为necessary,important,impossible,strange,natural,advisable,desirable,urgent,essential等时,即“It+be+形容词+主语从句”,主语从句中的谓语动词要用虚拟语气,也就是“should+do”,should可以省略。如:
It is necessary that the problem (should) be discussed at once.
立刻讨论这个问题很有必要。
It is strange that he(should) have so many friends.
太奇怪了,他有那么多的朋友。
4.whoever,whatever,whichever引导主语从句
whoever=anyone who;whatever=anything that;whichever=anything which。
Whoever breaks the law should be punished.
无论是谁触犯了法律,都应受到惩罚。
Whatever was said here should be kept a secret.
这里说的话都应当保密。
【即学即练】单句填空
1. is so breathtaking about the experience is the out-of-this-world scene.
2.It happened the plant downtown needed eight kids for temporary help during our spring break.
3. will be in charge of the project is quite important.
4. Tom moved to Canada suddenly remains a puzzle.
