星期一的早上,当我走进那个昏暗的房间后,屋子的主人们立时骚动起来。在屋子的正中央及四周的墙边排列着三层偌大的隔板。每层隔板上全都摆放着用金属制成的笼子。实验用的老鼠们就生活在这些方形笼中。它们就是这间屋子的主人。 On the morning of Monday, when I walked into the dark room, the room’s owners immediately stir up. In the middle of the house and around the wall are arranged three layers of large partitions. Cages are made of metal on each partition. Experimental mice live in these square cages. They are the masters of this room.
