T：Think again！In fact there are many accidents happening in people’s homes.Now let’s learn Lesson 16 to know about them.Are you ready? 设计意图：此环节通过师生间的对话导入本课的话题“在家是否安全”，预热本课的词汇和句型，为下面课文的学习做好铺垫。

二、展开过程，探究新知

T：Please read after me.(The Ss follow the teacher two times) (给学生几分钟的时间背诵) 设计意图：向学生呈现本课的生词，为下面学习课文做好充分的准备，学生互动，再次为下面的阅读做准备。

Step 3：While-reading

Task 1 Read the lesson and complete the table. 学生快速读课文，读完后，分小组到黑板写下问题的答案，每栏只限一个小组回答。

T：Boys and girls，it’s our reading time，in this procedure，we will read the lesson and complete the table of Exercise 1 on Page 41.Let’s see what it talked about.I will give you five minutes to read the lesson.When you finish it，please come to the front and write the answers.Each group can only write an answer to a question.Ready？Go! Task 2 Read the article aloud after the recorder.

教师播放对话视频，播放一句，暂停一次，学生观看视频并跟读对话。

T：Boys and girls，it’s our reading time，please read after the video，and you should pay more attention to your pronunciation and intonation，try your best to imitate it，clear?

设计意图：本活动设计在读课文之后，学生对课文内容已经有了一定的了解，跟着视频大声朗读课文可以加深对文章的理解，并且对于学生的准确发音以及培养他们的语感有重要的作用。

Task 3 Work in group of 8 to deal with the key words，phrases and sentences. 教师把学生分为8人一组，学生通过合作探究找出大屏幕上出现的重点句子，并学习。

the key words，phrases and sentences：

1.Can people prevent certain accidents？人们能阻止事故吗？

prevent动词，“防止；阻止”。常用句式：prevent sb. from doing sth.阻止某人做某事。

2.Many people hurt themselves by falling off chairs.很多人从椅子上掉下来而伤着自己。

themselves反身代词，“他们自己”，在句中作hurt的宾语。fall off...从……跌落。by＋doing sth.意为“通过……的方式”。

3.Don’t use water to put out kitchen fires.不要用水去扑灭厨房的火。

本句为祈使句的否定形式。其构成为：Don’t＋动词原形。意为“不要……”。use sth. to do sth.用某物做某事。to do不定式表目的。put out熄灭。

4.Use baking soda or salt instead.用小苏打或者盐代替。

本句为祈使句的肯定形式。其构成为：动词原形＋其他。salt名词，“盐”。其形容词为salty，“咸的”。

5.Be careful with your knives.小心你的刀。

be careful with...当心……。

6.Be sure to keep the bathroom floor dry after you have a shower or bath.

当你洗澡后确保浴室的地板是干的。

be sure to do sth.一定做某事。

(给学生一段时间背诵这些句子和知识点。) 设计意图：学生通过组内合作讨论，探究，找出对话中的重点句子和短语，把所学的知识转化为学习能力。

Task 4 Drill time. Do Exercise 2 and Exercise 3 on Page 41. Step 4：Group Work

教师把全班分为8组合作探究，讨论在家应该怎样保持安全。最后每个小组代表到前面利用投影仪边说边展示他们的成果，根据表演程度加星。这样掌握知识深刻，不易忘记，达到了教学的目的。
