I. 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。 　　

This further proved the strength of our economy.这进一步证明了我们的经济实力.。　　

2). prove+直接宾语(sth.)+to+间接宾语(sb.)

The difficulty was how he could prove his ideas to other scientists.困难在于他怎样向其他科学家证实他的想法.。
