　　Step 4. Consolidation

　　[课件展示]教师总结这一节课的语言点。(共有两页，教师点击按钮可进入下一页的consolidation)

　　1. Walking is good for health. 走路对健康有益。

　　Walk是动词，不能做主语。若要用walk做主语，就需在Walk后加—ing，即用walking做主语。动名词是动词的另一种非限定形式。它在句中起名词的作用，可单独使用或引起短语，做句子的主语、表语、宾语或介词的宾语。如：

　　Reading in bed is bad for you eyes.主语

　　2.Be good for 意为“对….有益”，与be bad for（对……有害） 相对。如：

　　Doing morning exercises is good for health.

　　Eating too much is bad for health.

　　3．Take the bus

　　take在句中是“乘，搭”的意思，表示一种行为。而“by+ 交通工具名词”则表示一种方式。如：

　　You can take the No.5 bus.

　　My mother often comes back home by bike.
