答
选A Why don't you 后加动词原形，为何不。。。？表建议
Let's 后加动词原形 让我们 祈使句 表建议
What about 后加动词ing形式 。。。怎么样？表建议
Would you mind 后加动词ing形式，你介 意。。吗？表征询。据题意可知选项A更恰当
答
A Why don't you
答
选择A，Why don't you buy a ring for her ？为什么不给她买个戒指？
疑问句很显然不用Let's ，What about 中因为about是介词，所以后面要接—ing ，Would you mind 也应该接—ing 才对。
答
选A.Why don't you
答
A
表建议：why don't you do sth.
而：Let's do sth.后面用句号,what about / would you mind + doing
