1、学生需理解定语从句的定义。定语从句在句中作定语，修饰一个名词或代词。被修饰的名词或代词即先行词。定语从句通常出现在先行词之后，由（关系代词或关系副词）引出。如： Do you remember everything that I told you ? 你记住我告诉你的每一件事了吗？在这句话中，everything 是先行词，that 为关系代词，在定语从句中充当宾语。
2、学生掌握定语从句的关系词。关系词放在先行词和定语从句之间，起连接先行词和定语从句的作用，同时在定语从句中充当一个成分。
3、定语从句中需注意的情况；（1）关系代词只能用that—缇吾怩舭—先行词是all,anything,somethin爿讥旌护g,nothing,everything,none等不定代词时，如：That's all that I could do at that time. 我当时只能做那么多了。——先行词被形容词最高级，序数词，以及last,any,only,few,much,no,very等词修饰时，如：This is the best hotel that I know. 这是我所知道的最好的旅馆。——先行词既指人又指物时，如：Lily took photos of the things and people that she was interested in. 莉莉把它感兴趣的人和物都拍下来了。（2）关系代词在句中作主语时不能省略。如：The tall man who is playing basketball is my father. 那个打篮球的高个子男人是我父亲。（3）关系代词whom和which， 在介词后，作宾语时，不能省略。如：The beautiful Lady to whom you just talked is Miss Wang. 刚才和你谈话的那位漂亮女士是王老师。（4）关系副词相当于“介词+which”结构。如：This is the house where Deng Xiaoping once lived. =This is the house in whichDeng Xiaoping once lived. 这是邓小平住过的房子。
