本单元课文注释与疑难解析1. It was predicted as early as the 1700s that English would one day be the global language and that has proved to be the case in the last few decades. 早在18世纪人们就预言总有一天英语将会是全球性语言，最近几十年已经证明情况正是如此。

It was predicted that.... 这是一个由形式主语it引导的句子，意思是“据预测……”，可改作：People predicated that... 此句型是本单元的重点句型和语法。

又如：It’s predicted that Stirling’s population will increase by 10.4% between 2002 and 2016, and employment will rise by 4.5% between 2001 and 2006. 据预测，从2002年到2016年，斯特灵的人口将增长10.4%；从2001年至2006年，就业也将增加4.5%。

相类似的句型还有：It is reported that there was a bad traffic accident in India last week.It is told that he will take a trip abroad.It is thought that the price of the clothes is high.It is believed that the girl will be fit for the office.It is hoped that China Football Team will win.It is suggested that the government do something against pollution.prove是个常用动词,也是一个多义动词.由于它的用法比较复杂,现归纳如下prove vt.证明;证实, 用法如下:1). prove+名词/代词He has proved his courage in the battle.他已在作战中证明了他的勇气。

选修7重点语法汇总Unit19一.名词性从句在复合句中起名词性作用的句子叫名词性从句。

名词性从句可分为主语从句、表语从句、宾语从句和同位语从句。

主语从句引导主语从句的连接词主要有三类：连接词that，whether，if；连接代词what，who，whose，whatever，whichever，whoever等；连接副词when，where，why，how等。

1.连接词that，whether，if引导①That the college will take in more new students this year is true.今年这所大学将招收更多新生是真的。

②It was doubtful whether/if the manager knew the details of the plan.经理是否知道计划的细节还不确定。

【注】(1)if引导的主语从句主语从句不可放在句首，只能放于it作形式主语的句子中。

Whether引导的语从句既可放在句首也可放在句尾，if和whether在句中都不充当成他，意为“是否”(2)形式主语it替代主语从句。

常见的it替代主语从句的句式主要有以下几种：A. It+系动词+形容词(possible,easy,necessary,polite)+that从句。

如：It is quite clear that the whole project is doomed to failure. 很清楚，整个计划注定要失败。

B. It+系动词+名词(no wander,a pity,an honor)+that从句。

如：It is no wander he was so sad.难怪他这么伤心呢。

C. It+be+v．ed(known,said,expected,thought,reported,etc.)形式+that从句。

如：It is announced that the plan has been successfully carried out. 据宣布计划已经顺利实施。

Period Five Grammar & Writing一、名词性从句定义：在复合句中起名词作用的从句叫名词性从句。

名词性从句的功能相当于名词，根据它在句中不同的语法功能，可分为主语从句、宾语从句、表语从句和同位语从句。

名词性从句使用陈述语序。

引导名词性从句的连接词分为三大类：1．连接代词：what，which，who，whoever，whatever，whichever等。

连接代词一般在从句中作主语、宾语、表语、定语等。

What we should do next remains unknown.我们下一步该干什么还不知道。

2．连接副词：when，where，why，how等。

连接副词一般在从句中作状语。

Where the party will be held has not yet been announced.还没有宣布晚会将在何处举行。

3．从属连词：that，whether，if。

从属连词that在句子中既不作成分也没有意义；whether/if在从句中不作成分，但表示疑问意义；主语从句位于句首表“是否”时只能用whether引导。

Whether the meeting will be held is still a problem.是否要开会仍然是个问题。

(一)主语从句主语从句在句子中充当主语，句子的谓语动词用第三人称单数。

[特别提示] that引导主语从句时，在句中不充当任何成分，无词义，只起连接作用。

不能省略that 引导的主语从句可用形式主语it代替，常见的句式有：1．It is/was＋形容词(necessary，likely，wrong，important，certain，strange等)＋that从句2．It is/was＋名词(a pity，a shame，a fact，an honour，no wonder等)＋that从句3．It is/was＋过去分词(known，expected，believed，thought，hoped，said，reported，proved等)＋that从句4．It＋特殊动词(seem，appear，happen，matter等)＋that从句That he will come to the conference has excited every one of us.他要来参加会议使我们每一个人都十分激动。
