2. B.
   
3. C.
   
4. D.
   

Answer 1

B
分析：物體鏡子里的像，與物體成軸對(duì)稱，結(jié)合選項(xiàng)即可作出判斷．
解答：只有選項(xiàng)B的圖形與原圖形成軸對(duì)稱．
故選B．
點(diǎn)評(píng)：本題考查了鏡面對(duì)稱的知識(shí)，鏡面實(shí)質(zhì)上是無數(shù)對(duì)對(duì)應(yīng)點(diǎn)的對(duì)稱，連接對(duì)應(yīng)點(diǎn)的線段與鏡面垂直并且被鏡面平分，即鏡面上有每一對(duì)對(duì)應(yīng)點(diǎn)的對(duì)稱軸．
