导语：定语从句，一个简单句跟在一名词或代词后（先行词）进行修饰限定，就叫做定语从句。在主句中充当定语成分。[1] 被修饰的词叫先行词。定语从句不同于单词作定语的情况，它通常只能放在被修饰的'词（即先行词）之后。希望大家喜欢!
作文中定语从句
When my first step into my university , I got astonished at the beautiful quiet fresh schoolyard which differed from my high school so much. And the big change came to the homework , then I seemed to be free of them at all instead of painfully wondering to choose A or B.
I had much more time for activities at university here. I like books , therefore I went to library frequently. Yet I enjoyed clubs as well, there I met lots of guys who shares the same interest. And sometimes I went to sports centres for exercise.
Life in university have appeared satisfactory so far , except for my English.
限定性定语从句
意义：
限定性定语从句对被修饰的先行词有限定制约作用，使该词的含义更具体，更明确。限制性定语从句不能被省略，否则句意就不完整，例如I met some one who said he knows you. 在引导限定性定语从句时，that有时相当于in which,at which,for which或on which
（1）Attitudes towards daydreaming are changing in much the same way that(in which) attitudes towards night dreaming have changed. 人们对白日做梦的态度正在改变，这与人们对夜间做梦的看法的变化有非常相似之处。
（2）I like the music for the very reason that(for which) he dislike it. 我出于某种原因喜欢这种音乐，而他恰恰与我相反。
（3）We arrived the day that(on which) they left. 刚好我们到的那天他们走了。
在限定性定语从句中，当关系代词在从句中担任动词宾语时，关系代词可省略。
（1）The book (that/ which) I am reading is very interesting. 我在读的书很有趣。
（2）Is there anything (that) you wanted? 想要什么东西吗?
