英语语法：非谓语动词的三种形式和用法

‍

前几期介绍了英语语法：助动词和情态动词、助动词be, have, do的用法、助动词shall, will的用法、助动词should, would的用法、情态动词may, might的用法、情态动词can, could, dare的用法、情态动词must, need, ought to, had better的用法。这一期学习英语语法：非谓语动词的三种形式和用法。

在谓语以外的句子成分中使用的动词一定要变词形（不能用动词原形），把动词原形变成不定式、-ing式或者过去分词，所以我们把这三种动词形式称为非谓语动词。

非谓语动词在保留动词特征（能带宾语、状语等）的同时，又兼有其他几种词类的特征，比如：

1.作主语、宾语时-兼有名词性质,相当于一个概念名词、意群（名词词组）或者名词性从句。

相当于一个名词：

Reading is great fun.

阅读很有趣。

相当于一个意群：

Reading extensively is very necessary.

广泛阅读是很必要的。

相当于名词从句：

For him to be dishonest is not easy.

让他变得不诚实可不容易。

2.作定语时-兼有形容语性质，相当于一个形容语、形容词词组或者定语从句（形容词性从句）。

相当于一个形容词：

We love moving movies.

我们喜欢动人的电影。

There are some fallen leaves on the ground now.

现在地上有些落叶了。

相当于一个形容词词组：

China will be a highly developed country in dozens of years.

再过几十年中国将成为一个高度发达的国家。

相当于一个形容词从句：

She saw a small bird wounded in one wing.

她看见一只有个翅膀受伤的小鸟。

作状语时-兼有副词性质，相当于一个副词、副词词组或者副词从句（状语从句）。

相当于一个副词：

She was happy to come.

她很高兴地来了。

相当于一个副词词组：

To be frank (frankly),I disagree with you.

坦率地说，我不同意你的话。

相当于一个副词从句：

Being late for class (=Because he was late for class), Tom was afraid to enter the classroom.

由于迟到，汤姆不敢进教室。

总要领：切记谓语以外用动词一定要变词形！

二、分析句子的英语语法结构，并翻译成中文

Thousands of Catholics have welcomed Pope Francis to Yangon, where has begun a three-day visit to Myanmar.  The trip – fraught with sensitivity and trepidation over how he will deal with the plight of the Muslim Rohingya – could be the trickiest yet of his papacy.  After touching down in the early afternoon, the pope was greeted by a large crowd at the airport, many waving yellow and white Vatican flags and dressed in T-shirts bearing the slogan of the trip, “Love and Peace”.  As he drove past, they screamed and chanted “we love Papa”.  The head of the Catholic church faces a difficult diplomatic balancing act on his first papal visit to Myanmar. 【英语外刊The Guardian】
