英语词源系列复习素材知识点精析精练yardstick/yen yardstick n.码尺；尺度 起源 这是一个复合词，由yard和stick组合而成，yard源自古英语单词geard(院子)或gerd(棍子)。在人类未发现测量工具之前，人们便用有固定长度的棍子作为衡量长短的标准。因此，原来只是一根普通棍子的yard变成了一个长度单位。而yardstick成为“码尺”，以后又由此引申出“衡量标准”“评价标准”等意。 例句 1.By any yardstick, that's a large amount of money. 用任何标准衡量，那都是巨大的金额。 2.This is a yardstick for measuring whether a person is really progressive. 这是衡量一个人是否真正进步的标准。 谷雨刷题王 单词快速记忆法 人教版初中英语单词 yen n.渴望，热望；日元vi.渴望 起源 晚清时期，广大中国人深受鸦片的毒害，导致许多家庭妻离子散、家破人亡。很多中国人吸食鸦片成瘾，十九世纪中期进入美国的华工中也不乏有烟瘾的人。美国人目睹了犯烟瘾者渴望吸食鸦片的模样，明白yenyin(烟瘾)对人的危害之大，由此也学会用这个名词来表达“渴望”“嗜好”。 也有人说yen是yenyin中“瘾”(yin)的讹用，美国人很可能原想以“烟瘾”喻指“渴望”“嗜好”，但却取错了字，把中国人的“瘾头”变成了英语中的“烟头”。 例句 1.I've always had a yen to travel around the world. 我一直非常渴望周游世界。 2.The pound remained frm against the dollar but fell against yen. 英镑对美元仍然坚挺，但对日元下跌。 (21) Peter ______ be really difficult at times even  though he's a nice person in general。 A. shall            B.  should       C. can             D.  must (22)  Liza ___  well not want to go on the trip --- she hates traveling。 A. will            B. can             C. must             D.  may (23) —What sort of house do you want to have？ Something  big？ —Well， it  _________ be big--that's not important。 A. mustn't         B.  needn't          C. can't           D. won't (24) Although this ____ sound like a simple task， great care  is needed。 A. must           B.  may              C.  shall            D.  should (25) You ______ be hungry already — you had lunch only  two hours ago！ A. wouldn't         B.  can't             C.  mustn't         D.  needn't (26) Some people who don’t like to talk much are not  necessarily shy；they         just be quiet people.      A.  must             B. may                 C. should           D. would (27) One of the few things you ____ say about English  people with certainty is that they talk a lot about the weather.
