[语法剖析]

语法点一动词-ing形式作表语

作表语的动词-ing形式包括现在分词和动名词。

1．现在分词作表语，往往具有形容词的性质，说明主语的性质、特征等。

The result of the game was disappointing．

比赛结果令人失望。

His life story sounds very moving．

他的人生故事听起来很感人。

[点津]作表语的现在分词，许多是由能够表示人们某种感情或情绪的动词变化而来的。常见的有：moving, interesting, encouraging, exciting, inspiring, boring, surprising, puzzling, amusing, astonishing ．．．这类分词有“令人……的”的含义，常修饰物。

2．动名词作表语多表示抽象性的或习惯性的动作，一般说明主语的内容。

What I am tired of is waiting here alone．

我厌烦独自在这里等。

语法点二动词-ing形式作定语

动名词和现在分词都可以作定语，但有所区别。

1．动名词作定语表示被修饰词的某种性能或用途，相当于for引导的介词短语。

我们学校有一个游泳池。

2．现在分词作定语时，它和被修饰词之间有逻辑上的主动关系，表示所修饰词进行的动作，相当于一个定语从句。

The boy playing football on the playground is my younger brother．

＝The boy that/who is playing football on the playground is my younger brother．

在操场上踢足球的那个男孩是我的弟弟。

[点津]现在分词、过去分词和不定式作定语的一般区别：现在分词表示正在进行或习惯性的动作；过去分词表示被动或完成意义；不定式表示动作尚未发生。

You should adapt to the changing situation．

你应该适应不断变化的形势。
