Unit1 How tall are you? Review  请快速说出图片中闪现的单词并拼写 Warm up Wu Yifan and his family are going on a trip to the countryside. Wu Yifan has a story to tell Robin. The story is about a duck and a tree. Let’s read the story together. Little duck is watching the sun go down. It is getting lower and lower, but his shadow is getting longer and longer. “Why is that?” little duck asks his old friend Old Tree. ”You are older and smarter than me. Tell me— why is my shadow longer when the sun gets lower?” Old tree says, “That’s easy, Little Duck. The sun goes down every day, and we grow older every day. Your shadow grows longer because you are growing taller. You are becoming a big bird!” Read and circle Read the dialogue again and finish the dialogue. 当太阳变得越来越低时，为什么我们的影子会越来越长？ 太阳刚刚升起，或即将落下时影子最长。 这时，太阳接近地平线，与地面的夹角（叫太阳的高度角）较小，形成的影子就最长。到中午时，太阳的高度角最大，形成的影子就最短。 * smaller taller heavier bigger longer shorter thinner older younger stronger √ √ 更清晰 更明亮 想到 变化 学习新知 Read and write Tips: go on a trip ——旅行，去旅行，进行一次旅行 countryside——乡村 学习新知 Read and write 学习新知 Read and write Tips: go down——下降 lower and lower——越来越低 shadow——影子 longer and longer——越来越长 比较级 + and + 比较级：越来越…… be动词+动词ing形式：表示正在做…… 学习新知 Read and write Tips: smater: smart的比较级，意思是”更聪明” 学习新知 Read and write Tips: easy:简单的 lower longer older taller 思考： Goodbye! *
