erbynotbrushingourteethunderarunningtap.设计思路：在本节课重点部分，我利用多媒体课件，先从图像、声音引出单词，让学生自己读出单词及词组，培养学生自主学习的能力。再通过看图说出图意操练相应词组，接着用多媒体播放旱灾影像，使学生在真实的生活中，感受水的重要性，

知道要节约用水。后面通过浪费水和节约用水的图片及做aquiz的形式学习本课的重点句型Howcanwesavewater?Wecansavewaterby___ing…Wecansavewaterbynot___ing…让学生选择不同的图片谈论怎么节约用水，可以考察学生刚刚学习的

结果，体验到学习英语的成就感。Practice:PeopleinGardenCitymakesomerulesaboutsavingwater.Helpthemfinishtheirwaysofsavingwater.Goodjobs.Conclusion:T:Nowwhatha

ter,startsfromme!设计思路：随着观看节水图片，及时对学生进行思品教育，使其无论在何时都要节约用水，并要养成良好的行为习惯。Today’shomework:1.Workbook6B,page61.*2.Writedownthedifferentwaysofsavin
