教学过程

一、创设情境，切入主题

Step 1：Warming up

T：Boys and girls，please answer my questions.What place makes you feel the most comfortable? Ss：My home. T：Yes.Do you think your home is a safe place? Ss：Yes. 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

Step 2：Pre-reading

T：OK，we have talked about some accidents.Now we will learn the following new words：prevent，themselves，slip，baking，soda，salt，knife.And this will help you to learn the lesson.Are you ready? Ss：Yes! 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 questions. 学生快速读课文，读完后，回答以下三个问题。

T：Boys and girls，it’s our reading time，in this procedure，we will read the lesson and complete the following questions.I will give you five minutes to read the lesson.When you finish it，please discuss with your partners in your group.Ready？Go! Task 2 Work in group of 8 to deal with the key words，phrases and sentences, after that, doing exercises to consolidate those main words and phrases.

教师把学生分为若干个组，学生通过合作探究找出大屏幕上出现的重点句子，并学习，及时做练习巩固。

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.Be careful with your knives.小心你的刀。

be careful with...当心……。

5.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。

6.It’s easy to slip and fall on a wet floor. It is adj to do sth.意为“做某事是怎么样的”。

7.Never leave small children alone in a bathtub.

leave sb./sth. alone.意为“让某人/某物独自留下”。

【辨析】alone,lonely (1)alone作副词,用于陈述客观事实,强调独自一人,没有别的同伴。

(2)lonely作形容词,意为“孤独的,寂寞的”,具有感情色彩。

(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 3 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 4 Consolidation time 巩固本节课所学重点单词、短语及句型。

Step 4：Group Work

教师把全班分为若干组合作探究，讨论在学校、回家及上学的路上应该怎样保持安全。最后每个小组代表到前面展示他们的成果，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。

T：Boys and girls! In today’s lesson we talk about how to keep safe at home.Several minutes later，I will ask your group leaders to come to the front to show your answers.Are you clear? Ss：Yes!

Make a poster.What should you do to stay safe at school? Give more tips for school safety.

Example：

Be careful with hot water.

Don’t climb trees or high walls.

设计意图：此环节通过小组合作形式，操练、运用本节课所学的句型，说明在家怎样保持安全。为学生创建了成果展示的平台，并将本课所学知识点升华为贴近实际生活的语言交际。在教学的过程中极大地激发了学生的兴趣。

三、布置作业
