1. T: Look, I have two blackbirds. They are sitting on the hill. Let’s enjoy. (展示小鸟手势表演，演示朗读歌词)

Two little blackbirds sitting on the hill, one named Jack and one named Jill. Fly away, Jack. Fly away, Jill. Come back, Jack and come back, Jill. Two little blackbirds sitting on the hill. One named Jack and one named Jill.

4. T: Let’s act and sing.

T: Let’s make a song and sing. For example:

Two little blackbirds sitting in the tree, one named Jack and one named Jill.

Too many cars, too much smoke.

Fly away, Jack. Fly away, Jill.   

Two little blackbirds sitting in the tree, one named Jack and one named Jill.

No more cars, no more smoke.

Come back, Jack. Come back, Jill.   

Let’s change to sing in pairs. (请同学一起试着换掉歌词的一部分再唱)

Two … sitting …, one named … and one named ...

...,...

...,...

Two little ... sitting ..., one named ... and one named ...

..., ...

…, …

Step 3 Sound time

1. T: In our city, we can’t see many birds, because the city is not clean. It’s not good for the birds to live. So can we throw rubbish on the floor?

S: No.

T: Do you throw rubbish on the floor?

S: No, I don’t. I put my rubbish in the bin.

T: Can we keep our city clean?

S: Yes, we can. We can put our rubbish in the bin.

T: That’s true. Now let’s listen to a rhyme. Pay attention to rising and falling intonation. (展示小韵文)

Boys and girls, do you know the rising and falling intonation? Now look at the rhyme. Can you find the rising and falling intonation?

S: Sentence 1: Do you throw rubbish on the floor? (闪烁升降调标记)

T: Yes. What else?

S: Sentence 4: Can we put our rubbish in the bin?

T: Yes. We should use the rising intonation when we read the first sentence and the fourth sentence. We should use the falling intonation when we read the other sentences.

2. T: When can we use the rising intonation? When can we use the falling intonation?

Here’s the table for you. (展示板书)

英语朗读时语调来自于音调的变化，以降调和升调为两种基本语调。

Are you clear?

3. T: Now we know how to use the rising and falling intonation. Let’s try to read these sentences. (展示句子)

1) Be careful, Tim! (祈使句)

2) Can you see the sign? (一般疑问句)

3) What does it mean? (特殊疑问句)

4) It means the floor is wet. (陈述句)

Well done. For Sentences 1, 3 and 4, we should use the falling intonation. And for Sentence 2, we should use the rising intonation. Try to read again.

4. T: 其实在英文的朗读中除了一般疑问句、反意疑问句和选择疑问句中要读升调，还有一些地方要注意读升调，比如长句子中间停顿读升调，结束读降调。如：We can take the bus and the metro to school. 还有A, B, C and D 一句中 A, B, C用升调，D用降调，如one, two, three, four and five，and之前的都需要读升调，five则要读降调。同学们，在今后的学习中，我们自己要慢慢体会并掌握哦。

说课

本节课的新授内容比较轻松、简单。在Song time环节中，教师呈现了一首简单有趣的歌曲，歌词讲述了一对鸟儿原本栖息在小山上，后来因为环境污染，双双飞走了，它们都很迫切地希望能重返家园。教师通过做手势的方式拍摄了一小段手影戏，增加了趣味性，也帮助学生理解和学习歌曲。随后要求学生在原来歌词的基础上创编歌曲，培养学生的能力同时也了激发学生的学习兴趣。

在Sound time环节中，教师呈现了陈述句的降调读法和一般疑问句句末升降调的读法。教师除了鼓励学生反复朗读，在听、读、模仿中感受英语的语调以外，还通过表格的对比、例子的引导等帮助学生感知并理解升调和降调。但教师要注意的是英美人在现实的日常交流中，一般疑问句的句末升调并不明显，甚至弱化到平调。因此，在平时的教学中不必追求刻意的升调，语调自然即可。本课的教学中，让学生掌握一般规则即可。

由于本节课的内容不多，难度不深，教师在本课的结尾处，还设计了一个巩固操练的环节。教师通过PPT课件呈现给学生一组环保画，学生通过欣赏和讨论，感受人类的破坏活动给地球带来的危害，让学生明白保护环境的重要性。学生在讨论中复习了本单元的一些主要句型，教师在语言上适当加以拓展，在训练学生的语言表达能力的同时也引出了下个单元的话题：保护地球。
