现在分词作定语的例句

问题描述:

现在分词作定语的例句
请比较一下,然后告诉我这两句话(作定语的现在分词短语在意义上相当于一个定语从句)的不同之处及原理是什么.
The man standing by the door is my English teacher.
The man who is standing by the door is my English teacher.
Did you see the homeless man sleeping under the bridge?
Did you see the homeless man who was sleeping under the bridge?

The man standing by the door is my English teacher.
standing作为形容词修饰这个男人,限制翻译,只可以译为,站着的男人.
The man who is standing by the door is my English teacher.
who作为引导词引导定从,[某个男人,站着的男人]你就这么理解吧.
以上两句意思是一样的.也么撒区别,看个人喜好爱用哪个用哪个.
下两句同理
