限制性定语从句与非限制性定语从句

• 限制性定语从句跟先行词的关系十分密切。最大的特点是先行词与从句紧密相连。
• 非限制性定语从句会有逗号把从句和主句分开。
• 当先行词被only等强调词,只能用that,不能用who
eg：I am the only person in our class that was praised by the teacher at the meeting.
• 非限制性定语从句不仅能修饰词,还能修饰句子
  eg：I have been relaxing in Dubai for almost half a month,which has been really nice.
