游戏说明：教师准备若干本单元句型条，每次同时呈现两个句型条在黑板上。请两个同学上台做游戏，一个面朝黑板，另一个背朝黑板。面朝黑板的学生用手指两个句子中的任一个，背朝黑板的学生随意说出其中一个句子，如果说的句子和指的句子一致，其他学生跟读该句子，猜出者加分。

(2) look and say

教师准备一个盒子，里面放着C部分图片。请学生在盒子里抽出一张图片，并根据图片内容说一句话。

S1：we should plant more trees

S2：I will water the young trees everyday

学生说完后可以将图片放回盒子里，重复使用，降低难度，鼓励更多的学生上台尝试。
