2.Grammar:主语从句
考点一:英语中的主语从句(The Subject Clause)在句中作主语,有以下两种结构:
1)主语从句位于句首。如:
What he wanted to see was an end to all the wars of the world.
他想要看到的是世界上所有战争的结束。
2)主语从句位于句尾,使用it作形式主语。如:
It was right that the temple was rebuilt.
庙被改建了,这很好。
在下列情况下,一般使用形式主语it,而将真正的主语从句放在后面:
①谓语部分含有seem,appear,be (im)possible,be a pity,be a wonder,be likely等。如:
It appeared to scientists on the earth that the stars had moved.
在地球上的科学家看来,这些星球已经移动了。
It's a wonder that you recognized me.
你能认出我来,真是奇怪。
②在It is known...;It is said...;It is hoped...;It is believed...等惯用的被动结构中。如:
It is believed that before writing was developed,people in China used to keep records by putting a number of stones together.
人们认为在文字发明之前,中国人靠把许多石头聚集在一起来作记录。
需要注意的是:当主语从句放在句尾而用形式主语时,形式主语只能用it,而不能使用this,that等代词。
考点二:主语从句的连接词可以分为以下三类:
1)that,whether
连接词that本身没有意义,不作句子成分,只表示从句的开始,位于句首时,that不能省略;whether含有"是否"的意思,whether可以加上"or not",其语意不变。如:
Whether we'll go camping tomorrow depends on the weather.
明天我们是否去野营取决于天气情况。
2)what,who,which,whose,when,where,why,how
这一类连接词,除了可以引导主语从句之外,在从句中又分别起代词、副词或形容词的作用,在从句中分别作主语、宾语、表语、状语和定语等。what,who,which,whose等又称为连接代词;when,where,why,how等又称为连接副词。试比较:
Who will do it doesn't matter.(连接代词who在从句中作主语)
