2, Do a free talk with Ss.

T: What’s your favorite subject? What do you like to do in your free time?

设计意图：该环节是让学生通过交谈，倾听同伴的讲解等方式，吸引学生注意力，使其回归课堂，以便进行本堂课的学习。

Stage II. Lead-in（4min）

Play the video Earth song and ask students what they have seen in the pictures. Then we can lead in the title Saving the earth .

StageIII: Pre-listening（8min）

Step1: Present the picture of example in 2,let the Ss observe the pictures and study the example in 2 .

T: What can you see in the left picture?

Ss: Flowers and grass.

Ss: There were lots of flowers and grass when I visited the village last year.

T: Can you see flowers and grass in the right picture?

Ss: No, we can’t.

T: Yes. Now there are not flowers and grass. So we can say…

Ss: Now the flowers and grass have gone. (板书)

(Show the old picture of the West Hill to the Ss)

T: Look at this beautiful picture. Kangkang and his friends had a picnic there two years ago. Can you guess where it is?

Ss: Yes, it’s the West Hill.

T: What can you see in the picture?

S1: Some flowers, a clean river and a big tree…

T: Right. The West Hill is a beautiful place. Can you see the bees and butterflies dancing there

(Point to the bees and butterflies, and then write down the words and phrases on the Bb)

T: So do you want to go there for a picnic?

Ss: Yes…

T: I’d like to. But now it has changed a lot. Look at this picture. Do you like it?

Ss: No.

(Teacher presents the new words and difficult sentences through the description of the pictures.)

VIII.教学反思

爱因斯坦曾说过：“兴趣是最好的老师。”本节课，我充分利用与安排的一些让学生成为课堂的主人，老师只是他们的导演与帮助者，激发学生学习兴趣，让他们在课堂上主动思考，主动探究，主动学习。课堂上多次组织孩子们质疑问难、合作学习、讨论交流，使他们在轻松愉快的学习活动中学会参与、学会求知、学会合作、学会创新，使不同层次的孩子在学习中获得成功的体验。使学生处于自信、放松的良好学习状态下突破难点、掌握重点。当然，英语作为一门语言，在英语课堂上我自己以及要求让学生尽可能的多说英语，创造英语思维，培养学生的英语口语交际能力。另外，多媒体辅助教学是现代教师必须要掌握的一门技术，在多媒体教学过程中教材的呈现则是多通道，多元化的。它集合声音，图像，动画和文字为一体。这样，抽象或枯燥的内容具有生动活泼的表现形式，可以调动学生参与活动，调动学生积极性，发挥学生潜力，从而达到最佳学习效果。

以上是我对这节课的理解与构思，当然还有很多不足与不完善之处，敬请各位专家老师批评指正。
