今天将为大家重点介绍主语从句,先来回顾从句的体系吧。 从句由名词性从句,形容词性从句和副词性从句三大句型构成。 那么,名词从句中的四个分支句型,具体又是怎样应用的呢?现在就让我们一起走进主语从句吧! 主语从句(Subject Clause) 主语从句,就是从句做主语。主语从句主要分为三类: that引导的主语从句 “that”引导的主语从句可以放在句首,例如: (1)That the seas are being overfished has been known for years. 海洋被过度捕捞,许多年来已经是人尽皆知的事情了。 但更为常见的是:用it作形式主语放在句首,that主语从句放在句末。 常见的主语从句的句型有: a. It+be动词+过去分词+that从句 例如: (2)As a child — and as an adult as well— Bill Gates was untidy. It has been said that in order to counteract this, Mary drew up weekly clothing plans for him. 童年时期,以及即使长大后,比尔·盖茨也不修边幅。据说为了改掉他的这个毛病,玛丽为他制定了一周着装计划。 (3)It is commonly believed in United States that school is where people go to get an education. 在美国人们普遍认为,学校是人们接受教育的场所。 b.It+be动词+形容词+that从句 例如: (4)Fortunately, the White House is starting to pay attention. But it’s obvious that a majority of the president’s advisers still don’t take global warming seriously. 幸好白宫已经注意到全球变暖的问题。但是很显然,总统周围大多数顾问仍然没有认真对待该问题。 (5)It is necessary that we should master a foreign language. 我们很有必要掌握一门外语。 c. It +be动词+名词短语+that从句 例如: (6)It is an established fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or grey. 事实证明,如果把工厂的机器漆成橘黄色而不是黑色或灰色,工人就会干得更勤奋、更出色,事故也会更少。 (7)It is a truth universally acknowledged that a single man in possession of a good fortune must be in want of a wife. 一个众所周知的事实是,一个单身汉若是非常有钱,那么他一定想要找个妻子。 d. It+不及物动词+that从句 通篇浏览下来,你会发现“it作形式主语放在句首,that主语从句放在句末”这样的句式还是很丰富地,他们的用法你能区别开吗? 做个练习试试看吧! 1. _____ hard water does not mix well with soap. A. That is a well-known fact B.
