创设情境
目标领航 Ⅰ. Lead in
Play a guessing game: Play some strange sounds, such as the sound of wind, rain, train or a cat… and then ask students:
Who is the noise maker
What might it be happening
Guide students to guess and tell the reason.
(环节说明：读前播放各种各样的声音，既可以让学生练习一下用情态动词进行推测，又可以让学生有一种神秘感，从而激发学生学习本课的兴趣，为下一步的阅读做好准备。)
自学展示
Ⅱ. Work on 3a－3c
Ask students to read 3a quickly and then answer this question: What’s happening in the town
(环节说明：从Step 1的各种怪声引入3a，让学生回答问题是为下一步学生选择本文标题做好准备。)
1. Ask students to read the article quickly and choose the best title from A, B and C.
2. Check the answer and ask students to tell the reason.
Work on 3b
Read the article again and find words to match the meanings.
Work on 3c
1. Read the article carefully. Fill in the chart.
2. Work in groups to discuss the answers in 3c.
Retell the article
Ask students to retell the story according to 3c. Use their own words as much as possible.
(环节说明：训练学生获取有效阅读信息、归纳主题的能力，然后由浅入深，层层推进。通过3c表格让学生把握文章的具体细节；根据表格复述课文既是检验对课文的掌握程度，也是一种语言的输出。)
Make a conversation
Work in groups of seven. One acts as a reporter, and the other six act as different residents in the neighborhood. Role-play the text. Try to use their own imagination and make their new conversation.
(环节说明：七人一组，每组以记者采访报道的方式重现文本内容，既可以将输入转换为输出，又可以让小组成员发挥自己的想象，补充相关内容。)
合作探究
反馈交流
Grammar Focus
1.读Grammar Focus中的句子填空：
这是谁的排球？________ ________is this
一定是卡洛的，她喜欢打排球。It _____ ____Carla’s. She loves volleyball.
这是谁的发带？Whose _____ ______is this
可能是May的。或者可能是属于Linda的。他们都留长发。
It _____ ____Mei’s hair band. Or it ______ ____Linda. They both have long hair.
那天晚上你看见了什么？What did you see______ _______
我不太确定，但肯定不是一只狗。它比较大。我想可能是一只熊或者狼。
I’m____ ______, but it ______ _____a dog. It was bigger. I think it _________ a bear or a wolf.
2.观察总结语法知识点：
情态动词 must, might, could, can’t 后接动词原形, 可以表示对现在的情况的 .
可能性: must> can/could > may/ might 否定：
1.must：意为“一定；准是”。表示说话人对事物的推测的把握性非常大。
They are wearing school uniforms, they must be students.
“must have +过去分词”意为“一定……”，表示对过去情况的肯定的推测。
2. can: can表示推测时，常用于否定句、疑问句中，can’t意为“不可能；应该不是”。常用句型为：“can/can’t be +表语”意为“（不）可能……”，表示对现在情况的否定推测。eg: That can’t be Maria, because she’s in hospital.
3. could/might/may:如果表示对所推测事情没有很大的把握，用could或might或may。它们常用于肯定句或疑问句中，意为“也许；可能”。
迁移应用

小结提升
Summary :
一、学生先自主学习，再以四人一组的方式展开讨论：
1.除了上节课学习的用情态动词表示推测的句子，本节课出现了哪几句新的用情态动词表示推测的句子？
2.本课围绕什么主题展开讨论？关于此主题有哪几个方面的猜测？
3.关于此主题，你的推测是什么？
二、教师总结
本课围绕“小镇怪声”这个主题展开讨论，小镇居民各抒己见。文中共有六人发表了自己的看法，但这些推测并没有得到证实，小镇怪声仍然是一个未解之谜。本文主要句型仍然是用情态动词表示推测的句子。但本文新出现了两个对正在进行的动作进行推测的句子：It must be teenagers having fun. There must be something visiting the homes in our neighborhood.
