Question

定语从句除了修饰一整个句子以外，是不是都能改写成非谓语动词做后置定语？

Answer 1

回答如下：
你说得对，定语从句可以改写成非谓语动词中的(现在或过去)分词短语或不定式短语，但要注意它们之间的区别：
1. 现在分词短语作定语表示正在进行的动作或者表示目前的状态。例如：
The man who is standing there is my uncle = The man standing there is my uncle.
The house which faces south is a clinic = The house facing south is a clinic.
The water which is being heated will turn into vapour = The water being heated will turn into vapour.
2. 过去分词短语作定语表示被动关系、完成的动作或表示目前的状态。例如：
The experiment which was done yesterday is successful = The experiment done yesterday is successful.
The man who is badly injured in the leg is a driver = The man badly injured in the leg is a driver.
3. 不定式作定语表示将要做的动作。例如：
The students who will take a trip to the Great Wall tomorrow come from Shanghai = The students to take a trip to the Great Wall tomorrow come from Shanghai.
The bridge which will be built next year will be 100 metres long = The bridge to be built next year will be 100 metres long.
