Step1 Revision

T: Today we’ll still learn “Unit6...” 

1. Grammar time

T: (老师出示词组，同学们快速读一读，跳出小老虎图片就拍一次手) In the game there are some phrases . Let’s review them.

2. Practice time

Fill in the blanks

3. Act time

T: I’d like someone to act as the story time.

a. 先出示文中有图片的单词如：clean , dirty , air , factory , smoke , rubbish

clean 干净的  a clean chair , a clean room , clean windows

dirty 脏的    dirty hands , a dirty street ,dirty shoes

air 空气      clean air , dirty air , by air

factory 工厂  clothes factory , food factory , many factories , in the factories

smoke 烟     black smoke    Don’t smoke. (作动词用)

rubbish 垃圾   rubbish bin

Step 2 Grammar time

T: Now, boys and girls, turn to page 60, look at the questions.

T:出示Grammar time 的完整图片。

2. 语法要点归纳：

1) What 作为疑问词看作是单数，所以动词make使用了第三人称单数形式。

2) Smoke 和rubbish都是不可数名词。一般现在时的肯定句中，主语是不可数名词，谓语动词也用第三人称单数形式。

3) Make和keep的不同用法：

Make 的意思有很多，做，制作，制造，整理，获得等，在本单元中的意思是“使……变得”，make+sth/ sb+形容词 。如：

Smoke from cars makes the air dirty. 汽车排出来的烟使空气变得肮脏。

Rubbish makes the steeets messy and dirty. 垃圾使街道杂乱无章。

Keep的意思是保持，经营，饲养，遵守等，本单元中的意思是“保持”。

例如：We can put rubbish in the bin to keep our city clean. 我们把垃圾放进垃圾桶能让我们的城市保持干净。

Trees help keep the air clean. 树木有助于空气保持清新。

3. Make some sentences.

Can you make some sentences : What makes … dirty? What makes … messy and dirty ?

Step 3 Play a game (Magic eyes)

教师出示图片，同学们说出相应短语，好的行为就拍手，不好的行为就双手交叉置于胸前。

T: The city is dirty. So what can we do to keep our city clean? Talk to your partners.

Step 4 Fun time

T: Boys and girls . How do you think of our school ? Is it beautiful ?

T: Is it clean ?

T: Do you want our school to be cleaner and more beautiful ? What can we do to keep our school clean? 

Here is a passage about it . Can you read it ?

Our school is big and beautiful. It is often clean . But sometimes there is some rubbish in the corner or on the grass. In the classroom there is some rubbish on the floor. I hope it can be cleaner and more beautiful. What can we do to keep our school clean ?We can… We can… We can… We can…

板书设计： Unit6 Keep our city clean

教学反思：

本课是在学习的过程中要求教师以多种形式练习句型“What makes the air dirty? What can we do to keep our city clean?”找出城市问题形成的原因，并寻求解决办法。可以采取问卷调查的形式。学生做一个问卷，去学校或是小区里，或是大街上进行随机调查，根据回答最后进行汇总，做出一个表格，明确地看出存在的问题及解决方法。让学生和老师分享各自的调查内容。

调查时可以广泛咨询意见，挑出最好的建议，可以将建议分发给学校的老师和同学，或者自己的邻居，让大家形成保护环境的意识，防止随处倒垃圾等不文明行为的发生，以共同保护我们这赖以生存的家园。
