什么叫非限定性定语从句？

Question

如题所述

Answer 1

简单的说，就是限定性前面没有逗号，而非限定性定语从句有逗号隔开的
在全句子中，限定性对原句的影响大些，去掉的话可能影响理解；而非限定性定语从句只是起到补充和解释的作用，影响不大，例如：Do you remember the teacher who taught us English in the middle school?（去掉影响原句的理解）2. Water consists of hydrogen and oxygen, as is known to all.（非限定性定语从句，可以去掉）3. One of my colleagues who/whom you are familiar with will come today..（不可以去掉）4. The general’s daughter, whose name is Jane, gave me a sweet smile..（可以去掉）5. We are all proud of the Great Wall, which is one of the man-made wonders of the world..（可以去掉）6. My father, who is an English teacher, often encourages me to work hard.（可以去掉）
