这组词都可表示“符号,标志”。它们的区别是: 1.symbol指作为象征或表达某种深邃意义的特殊事物; sign指代表具有固定意义的一种简明的符号或标志; mark指在其他事物上留下的清晰可见的印痕或先天固有的标志; token指表示爱情、友谊等的纪念物或礼品等。例如: She had a silver peace symbol hanging on a chain around her neck.她有一个银制的和平标志挂在项链上。 She put her finger to her lips as a sign to be quiet.她将手指放在唇上表示应安静。 He gave his wife a ring as a token of his love.他给他爱人一枚戒指,作为爱情的象征。 2.sign与symbol相比较, sign的含义简单明了,容易体察,而symbol却含义深邃复杂。例如: I could not write my name, so I made the sign of the cross.我不会写我的名字,就画了一个十字。 3.token和sign的意思相同,但token比sign庄严文雅,通常用于严肃的场合,在一般情况下可以用sign代替。例如: Jenny's husband gave her a ring as a token of their first meeting.珍妮的丈夫送她一枚戒指纪念他们的初次见面。
