lest conj.惟恐,以免 历年真题:We booked rooms at the hotel lest we should find no vacancies on our arrival. 译文:我们预订了旅馆的房间以防我们到达时找不到住的地方。 名师导学:lest所接的从句要用虚拟语气should+动词原形,should可以省略。另外要和as(与 一样;当 之时;因为);once(一旦):although(虽然,尽管):unless(如果不;除非);if(如果;即使)等相区别。 liable a.易于 的,可能的,有责任的,有义务的 典型例句:When supply exceeds demand for any product, prices are liable to fall. 译文:当任何产品的供给大于需求时,价格就会有下降的倾向。 名师导学:①熟记考点be liable to sth./do sth.可能的;易于 的;be liable for 有法律责任的。②词义辨析:liable ,apt和likely在如下不定式结构中经常可以互换,但是这三个词的意思是有区别的。一条公认的语法规则认为,只有当主语受不定式所表示的动作或结果的不利影响时,才使用liable。apt通常表示主语有增加某种结果的可能性的自然倾向,而且说话者对此结果多少有些忧虑。 likely比liable或apt更具概括性,它并不说明增加了一个结果的可能性的主语是否具有何特性。另外,它也没有关于说话者或主语是否喜欢某一结果的暗示。如果 位足球教练说We are not to win,他可能带有讽刺意味,但如果他说We are liable to win,他的意思是他认为他们可能会输;只有说We are likely to win,,才明确表示有希望获胜。 想一想:liability Key:n.责任,义务,倾向,债务,负债 liberal a.心胸宽大,惊溉的;自由的,自由主义的 典型例句:When the little girl wanted to travel alone in America, even her liberal parents hesitate. 译文:当小女孩儿想独自去美国旅行时,即使她开明的父母也犹豫了。 名师导学:该词的动词是liberate,表示 解放,释放,解除 。另外要注意liberal的 慷慨的 的词义。例如a liberal backer of the arts 一位对艺术的慷慨支持者 。它的同义词是generous。 librarian n.图书馆管理员 典型例句:He ever worked as a librarian. 译文:他曾经当过图书管理员。 名师导学:表示人的后缀除了-ian外,还有-ist,-ant,-er,-or.librarian源自名词library(图书馆)。library图书馆里的+ian工作人员即 图书管理员 。 想一想:library Key:n.图书馆 license n.许可(证),执照 vt.准许 历年真题:A graduated license requires that a teenager first prove himself capable of driving in the presence of an adult. 译文:要获得驾照,一个年轻人首先得证明他在有成人陪伴的情况下能够进行驾驶。 名师导学:词义辨析:表 许可 时,license较正式,具有一定的强制力;approval有不仅许可而且赞同的意味;permit和allow常可互换,前者稍正式。注意在美语中名词和动词均为license,而在英语中license是动词,而名词则为licence。 想一想:licensee Key:n.获得许可的人,领到执照的人,许可证持有者
