【重難點分析】
1. why don’t you do sth.?
這是給別人提建議，建議某人做什么事情的句型。
如：
why don't we come more often? 咱們為什么不經常來這里呢?'
why don't you do it this way? 為什么不用這種方法做呢?
why don't you have another try? 為什么不再試一次呢?
why don’t you buy a book for your father? 給你爸爸買本書怎么樣？
這個句子還可以寫成why not do…?
如：
why not get her a camera? 為什么不給她買個相機呢？
這個句型還有發出禮貌地邀請的用法。
如：
why don’t you have a drink of tea? 請喝茶。= why not have a drink of tea?
2. how/what about…? 表示“……怎么樣/好嗎？”
這個句型是詢問聽話這一方對某事物的看法或者意見。about是個介詞，它后面要接名詞或者doing。
如：
how about his playing football? 他足球踢得怎么樣？
what about swimming with us? 和我們一起游泳怎么樣？
how about her english? 她的英語怎樣？
