本次教学，围绕 as 展开，训练孩子的句法意识。练习之前，让孩子看下面的句子。

① Mike eats an ice cream. （迈克吃着冰激凌。）

② Mike walks his dog. （迈克在遛狗。）

妈妈告诉孩子：英语里，有一个连接词 as 表示“一边…一边…”的意思，我们可以用 as 把这两个句子连起来，表示“迈克一边吃着冰激凌，一边遛着狗。”

妈妈在纸上写道：

Mike eats an ice cream + as + Mike walks his dog

= Mike eats an ice cream as Mike walks his dog.

写完之后，妈妈问孩子：找找看，这句话里，哪两个词是重复的？

孩子说：Mike 是重复的。

妈妈说：英语不喜欢重复，所以咱们把这句话改写成：

Mike eats an ice cream as he walks his dog.

妈妈用荧光笔，把句子里的“Mike”，“as”和“he”涂上颜色。妈妈还要告诉孩子，句子后面的“he”，就是代替句子开头的“Mike”。

接下来，妈妈鼓励孩子说：今天，我们练习用“as（一边…一边…）”，把 2 个句子合并到一起。

开始练习喽！
