▲英语中，有一类“使令性动词”，表示人的心理或情绪变化。由此变化而来的现在分词和过去分词属于同一个词源：现在分词表示事物本身的性质以及给他人的感受，意为“令人怎样”；过去分词表示人的心理和情绪受到的变化，是被动的感觉，意为“感到怎样”。一般认为，也正如你所说的那样，以-ed结尾的形容词多用于修饰人，以-ing结尾的形容词多用于修饰事物。但这只是一种表象，不是问题的实质。请看：

You always look frightenIng when you wake up.你醒来时总露出令人恐惧的样子。

You always look frightened when you wake up.你醒来时总露出感到恐惧的样子。

The little boy is very interesting. 这个小男孩很有趣。

The little boy is very interested in the toy. 这个小男孩对着玩具感兴趣。

▲为何出现上述两种情况？问题的关键在哪里呢？

我认为，问题的关键在于分词形容词的性质：“现在分词（的形容词）表主动，过去分词（的形容词）表被动”。-ing修饰人完全可以，-ed也可以修饰物（限于表情之类）。同一个人或事物，可以有两种结果：

You look frightening.

Since you look frightening, you have a frightening look.

You look frightened.

Since you look frightened, you have a frightened look.

▲问题的关键，不是告诉你多少类似an interested look的词组，而是你要明白里面的道理和区别。再给分析一下：

a satisfied smile（感到）满意的微笑 （这种微笑是在人感到满意后表现出来的微笑）

比较：a satisfying smile令人满意的微笑（这种微笑是让人满意的微笑。意味着笑得真诚自然，不做作。）

an astonished expression（感到）惊讶的表情 （这种表情是在人感到吃惊后显现出来的表情）

比较：an astonishing expression令人惊讶的表情（这种表情是让人吃惊的表情。意味着这个表情有些可怕，使人惊讶。）
