我们今天要学的习惯用语都有这个单词:edge。它最常用的意思是“边缘”,但是在今天要学的第一个习惯用语里edge这个词的意思却是刀剑的刀刃。
今天要学的第一个习惯用语是:on the cutting edge。 Cutting是指:切或者是砍。 Cutting edge原来指锋利的刀刃,但是大约在上个世纪五十年代时人们开始用on the cutting edge来表示在科学,研究和文学等方面比其他人都走在前面,处于最先进的地位。
我们听个例子。这段话说的是著名科学家爱因斯坦。爱因斯坦是犹太人,他逃出了希特勒德国的魔掌,在科学方面创造了历史。
:Albert Einstein was on the cutting edge of physics. His ideas revolutionized modern thought on space and time. And his work formed the theoretical base for the exploitation of atomic energy and brought us into the atomic age.
他说:艾伯特.爱因斯坦当时是物理学的先锋。他的思想革新了现代有关空间和时间的想法。他的研究工作成为利用原子能的理论基础,并且把我们引入了原子时代。
这里的习惯用语on the cutting edge意思是“最先进,或尖端。”
今天要学的第二个习惯用语是: have an edge on。 我们也可以把have an edge on这个习惯用语里的edge理解为利刃。大约在十九世纪九十年代,have an edge on成了习惯用语,用来表示在某种竞争中占上风。你也可以说have the edge over,或者have an edge over,它们和have an edge on的意思是一样的。
这个习惯用语常用在商界、政界或者体育报道中。比方说,要是某企业的产品比竞争对手的更好而占优势,我们说:The business has an edge on its rivals because of the better product. 要是政界一位候选人由于口才好而比政敌略胜一筹,我们就说:The candidate has an edge on his opponent because of his better speeches. 要是一个足球队由于球员身材高大,动作敏捷而胜过另一队,我们说:The team has an edge over another because its players are bigger and faster. 再听个有关政界的例子吧。这段话在说竞选参议员的Pete Smith。
:I think Pete Smith has the edge on his rivals in the race for the US Senate from our state. He's got the experience: he's been a Congressman for ten years, and he has a good record to run on. He's almost sure to win next November!
他说:我认为Pete Smith在本州竞选美国参议员的候选人中占有优势。他有经验,因为他已经当了十年众议员了,而且有良好的政绩作为参选的基础,他在十一月的竞选中几乎必操胜券。
这里的习惯用语have the edge on意思就是占有优势。
在今天要学的第三个习惯用语里edge这个单词回到了它的基本意义:边缘。这个习惯用语是:on the ragged edge。 Ragged可以解释为“撕裂的,破烂的”,也可以指凹凸不平的悬崖边缘。
想象一下你在漆黑的夜晚站在怪石嶙峋的悬崖边上,脚下的是松动的沙土石块,稍一闪失你就有粉身碎骨的危险。这正是on the ragged edge这个习惯用语的写照。我们再听个例子来体会on the ragged edge这个习惯用语的意义吧。
这位先生正在跟业务伙伴Mary商讨本企业岌岌可危的财务景况。
:Mary, I'm getting scared about our money situation in the firm. O our costs are way up. Unless we can get a quick loan somewhere, I'm afraid we'll be right on the ragged edge of going bankrupt.
他说:Mary,我对公司的财务景况感到很害怕。我们的销售在下降;然而开支却大大增加。 除非我们能从哪儿很快借到贷款,否则我们就会有破产的危险。
显然这里的习惯用语on the ragged edge意思是“处境危险的,在失败和绝境的边缘。”

中国学术期刊(光盘版)电子杂志社cutting edge 是什么意思_百度知道  Cutting Edge 3的大纲课时为48小时,共计12单元,平均每个单元4小时,在4小时内可以充分为学生讲解大纲规定的语法点、生词、课文分析、精听练习和话题讨论。但对于一对一的学生,前期课程通常只有20小时左右,要在20小时内讲完CE3全部内容,课上只能将教学中心放在雅思考试中高频的语法点上,Cutting Edge 3书中很多同样有价值的内容就需要学生课后自行吸收消化。因此在这里环球教育(原环球雅思)赵阳老师简单分享一些如何利用好Cutting Edge 3这本教材的内容,为雅思课打好先期基础。  Cutting Edge 3语法:每个单元大纲中都会列出两个语法点,这两个语法点也是每节课开篇要讲的内容。但大纲中规定的语法点难度适中,中等以上基础的学生都可以很快掌握,所以这一部分内容不会占用太多时间,课上辅助以相关的练习题,15至20分钟内解决这部分内容。授课重点集中在每个单元的课文中,用75-90分钟时间,通过课文讲解六大从句、伴随状语、虚拟语气、倒装强调等语法重点,每个单元辅以相应的句子翻译练习,建议学生按时按量完成布置的课后作业,才能保证课上的讲解有效、高效。  Cutting Edge 3听力:重点的语法内容过后,留给听力和口语的时间就只有20分钟左右。每节课会挑选接近雅思考试的听力内容带学生进行练习,让学生大致了解雅思听力的答题模式和语速。CE3收录的听力音频难度适中,非常适宜学生做精听和复述练习。建议学生课后每天拿出半小时时间,听一段本单元的听力录音,自行对照文本进行精听练习,在写和说的过程中,扫清不会的生词,培养语感,熟悉听力考试的语音语速。  Cutting Edge 3口语:每个单元的课文、听力和生词都是围绕一个主题展开的,口语讨论的部分,建议学生课后先完全掌握书后的词汇表,运用相关词汇,自行构思如何对本单元涉及的话题进行阐述,可以通过写作文的方式,一举两得。基础较好的学生也可以选择在头脑中构思,在下一次上课时对上一个单元涉及的话题进行阐述,目的一是检验是否能够灵活运用上节课中学到的语法和词汇,目的二是提前适应用大篇幅的英语阐述自己的观点。  综上所述,如果能够每天拿出定量的时间梳理Cutting Edge 3单词,语法,课文,听力和口语,在基础阶段,学生可以为雅思的学习打下良好的基础。
