1、Section Using language Grammarit作形式主语一、语法图解二、语法突破1概念it作为形式主语，代替句子的逻辑主语，并无实际词义。这可以保持句子的结构平衡，避免主语太长，显得头重脚轻。2用法it作为形式主语主要分为几种情况：(1)It is/was形容词(for sb.)动词不定式强调动作特征的形容词(如easy，difficult，hard，important，possible，wise等)常用于此句型。为了强调不定式动作的执行者，常在不定式前加for sb.。It is necessary for us to master some basic living sk
2、ills.我们有必要掌握一些基本的生活技能。(2)It is/was形容词(of sb.)动词不定式表示心理品质或性格特征的形容词常用于此类句型，如kind，nice，stupid，clever，foolish，polite，impolite，silly，selfish，considerate等，动作的逻辑主语和这些形容词可以构成主系表结构，因此这样的句式也可转化为“sb.be形容词动词不定式”。It is foolish of you to trust a person like him.You are foolish to trust a person like him.你相信像他这样的人
3、是愚蠢的。(3)It is/was名词(短语)动词不定式It is our duty to help the weak and the poor.扶弱济贫是我们的责任。(4)It is/was名词/形容词动词ing形式常用的名词和形容词：no good，no use，a waste of time，useless。It is no use arguing about the matter with him.和他争论这件事是没有用的。(5)It is/was形容词主语从句It is uncertain whether the project will be completed this fall
4、.这个项目能否在今年秋天完成还不确定。(6)It is/was名词(短语)主语从句常用的名词：a fact，a pity，a shame，a surprise等。It is no surprise that he has been accepted by the company.他被这家公司录用了，这并不奇怪。(7)It is/was过去分词主语从句用于此类句型的过去分词有said，reported，thought，announced，believed，suggested，decided，hoped等。 It is believed that the boy will soon recover
5、 from the operation.人们相信这个男孩手术后不久就会康复。(8)Itseems/appears/happens主语从句It appears that people are more dependent on the Internet.人们似乎更依赖互联网了。(9)It及物动词宾语动词不定式It took the workers three years to complete the project.工人们花了三年时间完成这项工程。3形式主语it与强调句中it的差别形式主语itit是句子的形式主语，真正的主语是句尾that引导的主语从句，去除句中的it和that则句子失去完整性
6、。强调句中it强调句结构为“It is/was被强调成分that句子其余成分”，结构词it is/was和that都无实际意义，删掉it is/was及that后句子仍然意义完整。It is strange that he should say I am unfair.(it作形式主语)真奇怪，他竟然说我不公平。It was in the park that they fell in love with each other at the first sight.(强调句中it)他们是在这个公园里一见钟情的。1harmonious adj.和睦的，融洽的；协调的；悦耳的(教材P42)Rathe
