问题描述：
Can you please____(not clean) the blackboard
填好请说明原因,我只知道Can you please do sth.
答
not clean
你反过来看You cannot clean the blackboard
或者 Please do not clean the blackboard
答
是don't clear
因为加上please就变成祈使句了，加上do是为了加强语气，用clear是因为can情态动词，动词用原型！
答
not clean
答
NOT CLEAN
CAN YOU PLEASE NOT DO Sth.
答
not please,因为此句型的否定形式就是please not do sth.
答
Can you please do sth的否定，换个not ，填 not clean 就是了。。。。
