foolish除去表示动作愚蠢、荒谬外，能否直接表示人愚蠢？这两句话是不是有误？
He is foolish.
Its foolish to do like this.
请问这句话中的红色部分是什么成分？
I just stood there feeling foolish and watching him. 我只不过傻傻地站在那里看着他。
谢谢专家老师！
1. foolish 既能够指行为、话语等“愚蠢的，傻的”，也可以指人“愚笨的，傻瓜似的”。如：
To accept their offer would be foolish. 同意他们的帮忙是愚蠢的。
We must put an end to this foolish behavior. 大家需要终止这种愚蠢的行为。
He is a foolish young man. 他是个愚笨的小伙子。
You were foolish to believe what he said. 你相信他的话太傻了。
你的以下两句都是对的：
He is foolish.
Its foolish to do like this.
2. 下面句子中的目前分词短语 feeling foolish and watching him 为随着状语，即随着谓语动词 stood 同时发生：
I just stood there feeling foolish and watching him. 我只不过傻傻地站在那里看着他。
3. Its foolish of sb. to do sth. 句式习惯上用 of，不需要 for。又如：
It was foolish of me to forget. 我真蠢，居然忘记了。
It’s foolish of you to believe her. 你相信她真是太蠢了。
比较同义句：
It was foolish of her to say such a thing.
= She was foolish to say such a thing.
她说出那样的话来，真是太蠢了。
