在选择引导定语从句的关系代词时，有如下要点： 1 由于关系代词在主句与从句间既起到联系作用，又在从句中充当一个成分，因此， 要正确判断关系代词在从句中的功能，如作主语还是宾语等。 2 当先行词指人时，关系代词可用who（做主语，宾语），that（做主语，宾语），whom（作宾语），whose（作定语） 3 当先行词指物时，关系代词可用that（做主语，宾语），which（做主语，宾语） 4 在非限制性定语从句中，指人时，只用who，指物时，只用which。 定语从句中的关系副词 定语从句的关系副词有：where, when, why 关系副词where: 当先行词在定语从句中做地点状语时， 关系词选择 where或prep+which。 He took me into a room where some old books were stored. Some old books were stored in the room. He took me into a room in which some old books were stored. He took me into a room which/ that/ \ some old books were stored in. The city lies at the spot where the two railways join. The two railways join at the spot. The city lies at the spot at which the two railways join. The city lies at the spot which the two railways join at. 注意：先行词的意义不能决定关系词的选择， 而是先行词在定语从句中所做的成分。如果先行词在定语从句中做的是名词性成分， 即主语，宾语， 表语， 则选择关系代词 ；先行词在定语从句中做的是副词性成分， 即状语， 则选择关系副词 。 The day that I can hardly forget is the day when I first met him. I can hardly forget the day. I first met him on the day. 非限定性定语从句 非限定性定语从句是制定语从句的先行词和关系词由逗号分开的情况。 在这种情况下，不论先行词在定语从句中做什么成分，关系词都不能省略。另外， that不能引导非限定性定语从句。 The family, who live upstairs, are fond of music. His mother, whom he loved deeply, died in 1875. The meeting, which was held in the park, was a success. He decided to find a place, where he could hide himself if enemy came. 限制性定语从句和非限制性定语从句： My sister, who is twenty, works in a bank. The man who came here yesterday has come again. 限制性定语从句是先行词在意义上不可缺少的定语， 如果去掉，主句的意思就不完整或失去意义。这种从 句和主句关系十分密切， 写时不用逗号分开。 非限制性定语从句和主句关系不很密切，只是对先 行词作些附加说明， 如果去掉，主句的意思仍然清楚。 这种从句， 写时往往逗号分开。 在非限制性定语从句中，指人时，只用who，指物时，只用which。 She looked at Jeff, who was waving his arms. Football, which is a very interesting game, is loved by most people in the world. * 一、重点单词： （1）v.更喜欢 （2）n.歌词 （3）n.心，内心 （4）adj.最近的（5）v. n. 展览 （6）v. 使…感兴趣 （7）pron. 无论什么 prefer lyric heart latest display interest whatever （8）v. 显示，暗示（9）adj. 诚实的 （10）v. 适合 （11）v. 期待，预料 （12）v. 增加，增大 （13）n.危险，风险 （14）adj. 味道好的 suggest honest suit expec
