记忆方法
1、single 的根表"一"（sim-/sem-），same（同一个）、similar（相似）、simple（简单）都是这一家，只是 m 变成了 n——lamp 和 lantern（灯、灯笼）正好是同一对换法，拿它俩对照就不容易写错。
2、义项全从"一个"散开：single room 单人间、a single ticket 单程票、single parent 单亲、网球 singles 单打；动词 single out 是把人单独挑出来。
3、singlet（背心、汗衫）就是 single 加指小尾巴 -et，它是照着 doublet（double 双层的紧身衣）仿出来的：那件是双层，这件是单层布料。
