12.ACD【解析】不妨设切点为(xo,(xo一1)e。),因为(x)=xe,所以切线方程为y一入=xoe(x-1),所以(x一1)e。一入=xoe（x0一1)，整理得入=-e(x6-2xo十1)，所以令g(x)=-e(x2-2x+1),则g'(x)=-e(x2-1),所以令g(x)=0,得x=±1，所以当x<-1或x>1时，g'(x)<0,g(x)<0,当一1 0,因为当x趋近于一∞时，8)趋近于0，g(-1)=-4,g(0)=-1,g1)=0,当x趋近于十∞时，g(x)趋近于一∞，所以函数g(x)的图像大致如图，-1gx)=-e'(x2-2x+1)4e所以当n=2时入=g(一1)=一4，故B项错误，此时+n<3成立：当m=3时，A∈(-是0），所以+n<3,-12<<0,-12<-4,故m可能等于一4，故C项正确：当n=1时，A∈(-0，-)U{0),显然X计”<3,故D项正确；综上，λ十<3，故A项正确.故选ACD项.

On a afternoon my friend Daming and I was playing basketball one on one.The game was fierce.anwereWhen jumping up A catch the ball,I saw an arm above his face.Daming's arm came down hard,righttomyinto my left cye as he got the ball.It hurts terribly.He kept apologizing while I found myself laughinghurtthrough the pain.I spent the next few days walked around with a black eye.For months afterwards I gotwalkinga laugh whatever I told the story and gentle joked with Daming about that incident.I think when anwhenevergentlyunhappy thing happens to us in life,and it is best to handle it with laughters and forgiveness.laughter
