why not talk about ( ) about universe.A anything interesting B something interesting

问题描述:

why not talk about ( ) about universe.A anything interesting B something interesting

B.something interesting
一般情况下否定或者疑问句用anything,但是why not 属于很礼貌地提问,是一种建议的语气,而不是语气强烈的质疑,所以用something.
例如:why not drink some water .喝点水怎么样?
