三、教学步骤
Step One Lead-in
1. Brainstorm: If you have a million dollars, what will you do?
Let the students express their opinions freely, the teacher writes their ideas on the Bb.
Bb: If I have a million dollars, I will buy a big hou for my parents.
If I have a million dollars, I will give much money to the poor.
If I have a million dollars, I will donate some to the Hope Project.
If I have a million dollars, I will travel all over the world .
……
（设计意图:用Brainstorm的形式导入，这话题是学生常常谈论的，引起学生的兴趣，导入主题条件状语从句。）
Step Two Language in u
条件状语从句
1. 概念：由连接词if，as/so long as ,unless等引导的状语从句叫做条件状语从句。
e.g.：If it doesn't rain tomorrow, we will go to the zoo.
If you open the door，I will come in.
2. 构成：
Show five ntences on the screen, have the students pay attention to the part of verb and try to find the structure of conditional adverbial claus.
If it doesn’t rain tomorrow, we’会考题ll go to the park.
You’ll fall behind the others unless you study hard.
Mobile phones can help students relax as long as they 思念故乡的诗u it in their spare time.变生肘腋
You will succeed in the end unless you give up halfway.
If you ask him, he will help you.
总结：（注意条件状语从句的主句、从句时态的变换） 主句用一般将来时，if或unless等引导的条件状语从句用一般现在时。另外，主句是祈使句或含有情态动词，从句也用一般现在时。
Practice: Underline the correct answer.
1. If he (will have/have/has) money, he (will build/build/builds) a science lab.
2. Don’t wait for me if I (am/ will be) late.
3. They (won’t/don’t) go to the beach if it (will rain/rain /rains).
4. I (will call/ call) you if he (will stay/stay /stays) at home.
5. (Will /Do/ Does) he visit the muum if he (won’t / don’t/ doesn’t) get tired?
（设计意图:展示5个句子，帮助学生发现条件状语从句的构成, 并及时检测学生的掌握情况。）
3. 基本用法
1) if引导的条件状语从句,“如果’’，“假设”
e.g.: If it rains tomorrow, we won’t go on a picnic.
You will be late if get up late.
Plea call me if he comes next Sunday.
Can you call the policeman if you are in trouble?
2)unless 引导的条件状语从句,“如果不’’，“假设不”
unless = if...not.
e.g. Let's go out for a walk unless you are too tired.
=If you are not too tired, let's go out for a walk.
Unless you work hard, you will fall behind others.
=If you don’t work hard, you will fall behind others.
3) so/as long as引导的条件状语从句, “只要”
e.g. As long as he likes the bike, he can buy it.
You may borrow my book as long as you keep it clean.
在任何情况下，条件状语从句本身都不使用将来时态。
（设计意图: 掌握条件状语从句的引导词的区别及基本用法。）
4.条件状语从句if与宾语从句中的if的区别。
宾语从句中的if意思是“是否”，相当于whether，引导宾语从句，时态需根据语境确定。如果主句用一般现在时，从句可以根据具体情况选用时态，如果主句用一般过去时，从句必须用过去式的某种形式。条件状语从句中if 意思是“如果”， “假设”,遵循主将从现原则。
Show some ntences on the screen and have the students tell whether they are objective claus or conditional adverbial claus.
I don't know if it will rain tomorrow.（if 宾语从句）
If he comes, plea let me know. （if条件状语从句）
I’m not sure if he will come next Sunday.（if 宾语从句）
（设计意图: 掌握条件状语从句if与宾语从句中的if的区别。）
5. Complete Activity 12 Have the students finish Activity 12,and then have a check with the students as a whole.
（设计意图: 归纳总结条件状语从句的构成和基本用法。）
6. Complete Activity 13
（设计意图: 通过创设情景，把语法的练习融入对话情景中。）
7. Do Activity 14 Have the students complete Activity 14, then ask some students to read their compositions to the whole class and judge who did the best.
（设计意图: 通过创设贴近生活的情景，用所学语法知识简单描述智能手机的利弊，达到学以致用的目的；通过朗读自己的作文，训练学生听力及语言组织能力,并及时评价。）
