Step I 学习理解
活动一:识别定语从句(SB，P6，Part 1)

【设计意图】通过寻找定语从句的活动，先让学生找出先行词、关系代词和关系副词。然后进行讨论，在语境中总结出定语从句的用法。
活动二:使用定语从句改写句子(SB，P6，Part 2)
1.Rewrite the sentences using relative clauses.
EXAMPLE：
I have dwnladed that free app，but it desn’t wrk well. →The free app ( which/that) have dwnladed desn’t wrk well.
(1)He shwed me a pht in his rm. It was a pht f a famus cultural relic in Egypt. →The pht which he shwed me in his rm was a pht f a famus cultural relic in Egypt.
(2)The prject team helped prtect the natinal parks in the United Republic f Tanzania. It was frmed by members frm fifteen cuntries.→The prject team which was frmed by members frm fifteen cuntries helped prtect the natinal parks in the United Republic f Tanzania.

2.Discuss with a partner.
(1)Which relative prnuns can be deleted in yur sentences?
(2)When can yu g withut the relative prnuns like this?
句（1)、句(4)可以省略，即关系代词在定语从句中充当宾语的时候可以省略。
【设计意图】通过用定语从句改写句子，让学生在练习中感受并总结出定语从句的用法：如何选取关系代词、关系副词将主从句连接起来，以及什么时候可以省略关系代词。
Step I 应用实践
活动三:用定语从句下定义(SB，P6，Part 3)
Wrk in pairs and play a game f definitins. One asks the questins belw and the ther answers them with relative clauses. Wrk ut tw mre questins f yur wn.
EXAMPLE：

【设计意图】在对定语从句有了初步了解和认识之后，设计了用定语从句给名词下定义的活动，有助于学生加深理解定语从句，丰富句子使其表达更具体、生动，并提高学生在语境中使用语言的能力。
Step III 迁移创新
活动四：我说你猜
1.Ask students t describe a persn using attributive clause.
2.Ask students t speak ut their sentences and ask thers t guess wh they’re describing.
E.g.：
(1)He is a man wh first wn the Nbel Prize as a Chinese.
(2)She is a wman wh stayed in the habitats f chimps t study their behaviurs.
【设计意图】在学习和练习了定语从句的用法之后，让学生置入真实的情境中。通过学生用定语从句描述不同 的人物——可以是课本中学过的，可以是名人，也可以是自己身边熟悉的人，让其他同学猜这些人物，既和之前课时所学紧密联系，又在写与说的过程中加深了学生对定语从句的理解，提高了学习语法的兴趣。
