四、教学过程

Step 1：Warming up What job do you want to do after you graduate from high school？What do you need to study to get that job？What else do you need to do？Would you like to be a biologist？Dr.Chip Taylor who is a biologist will give us a lecture. 设计意图：所有的学生都有自己的梦想，当他们长大了，他们想干什么？为了实现梦想，必须在学习上付出努力，让学生明确学习目标。

Step 2：Presentation

1.就插图进行提问，教学新词butterfly。

2.阅读课文，画出未学的生词，理解本故事的中心大意。

3.读课文，找出并翻译下列词组。

(1)长大________

(2)引起某人的注意________ (3)多达……________

(4)动身去________ (5)砍倒________ Step 3：Reading Students read the text again，do Exercise 1 in “Let’s Do It！”

Keys：return，spend，lay，rest，kill，find Step 4：Work in groups Student A writes a person’s name in the first column，folds the paper and passes it to Student B. Student B writes a statement beginning with “who”，folds the paper and passes it to Student C. Student C must finish the sentence and read it out loud. Miss Zhang who is a teacher teaches us English. Li Ming who is a student studies in a university.

设计意图：仿照例子，熟悉定语从句的语法构成。

设计意图：通过训练，检查他们对本课单词的学习

Step 5：Grammar 在复合句中修饰主句中的某一名词或代词的从句叫作定语从句。被定语从句修饰的名词或代词叫作先行词，通常位于定语从句之前。引导定语从句的关系代词who(whose，whom)，which，that；关系副词有

when，where，why。关系代词和关系副词位于先行词和定语从句之问。定语从句的结构：先行词＋关系词＋定语从句。

Step 6：Homework

Do Exercise 2 in “Let’s Do It！”.
