英语方面的问题：wear、put on \be in \dress的区别

wear和dress表状态,wear接衣服等,可用进行时,dress接人,be dressed in, put on表动作 It's cold outside. Put on your warm clothes.
to put on (穿,戴)特别指穿衣服、穿鞋、戴帽、戴眼镜也用这个成语.英文中还有wear和dress二字也是穿的意思.可是wear是继续的动作,表示穿着的状态,而put on是一时的动作.下面两个句子都是错的：
I shall wear my overcoat before I go out (应用put on). In such cold weather I put on my overcoat all day （应用wear）.dress的意思是
①put clothes on后面的受词一定是人,如dress a child, dress oneself, be dressed in white,
②put on clothes, vk Get up and dress quickly. （快点起来穿好衣服.）
【例：】
(1) Mary put on her hat and left the room.
玛丽戴上她的帽子就离开这屋子.
(2) Why is John putting on his hat and coat?
约翰为什么穿衣戴帽呢?
