词汇	scan
词根词缀	词源： scan (v.) late 14c., "mark off verse in metric feet," from L.L. scandere "to scan verse," originally, in classical L., "to climb" (the connecting notion is of the rising and falling rhythm of poetry), from PIE skand- "to spring, leap" (cf.* Skt. skandati "hastens, leaps, jumps;" Gk. skandalon "stumbling block;" M.Ir. sescaind "he sprang, jumped," sceinm "a bound, jump"). Missing -d in English is probably from confusion with suffix -ed (see lawn (1)). Sense of "look at closely, examine" first recorded 1540s. The (opposite) sense of "look over quickly, skim" is first attested 1926. The noun is recorded from 1706. Scanner as a type of mechanical device is recorded from 1927. 词根记忆： v. 细看,审视;浏览;扫描n.扫描Having canceled X-ray scan, the cancerous candidate on the canvas ate the idle candles in the candy can.取消X线扫描后,帆布上的癌症候选人吃了糖果罐里的闲置蜡烛.
