设计意图：观看交通违规的图片，并导出if引导的条件状语从句“If you obey the traffic rules, you will get a fine.”“You will be in danger if you cross a busy road. ”同时达到情感教育的目的，教育学生要遵守交通规则。

Step 2: Compare the two sentence

设计意图：比较两个句子，引导学生自己发现if的含义及引出下面的讲解

Step 3: 讲解if引导的条件状语从句

一、位置（可前可后，从句在前用逗号与主句隔开）

结构与时态

1、if从句是一般现在时，主句是一般将来时

if从句是一般现在时，主句有情态动词

3、if从句是一般现在时，主句是祈使句

Step 4: 重难点突破

主语为you的条件状语从句与“祈使句+and/or+简单句”相互转换

Step 5: Practice

运用改错和单选题进行操练，加深对知识点的理解，复习中考题型
