( fortunately),2形容词的前面。,1动词的附近（指前面或后面）。,二、 选词填空解题步骤和技巧,(1)根据固定搭配 collocation,2 运用逻辑和语言知识储备解题,固定搭配：在选词填空中，约定俗成的固定搭配不是很多，诸如，我们所说的idioms等。但是，对固定搭配的另外一种理解是这种搭配很常见，比如：汉语说“学知识”，而英语不说“learn knowledge”, 而是“acquire knowledge”; 还有，要描述 rain 很大，我们用heavy修饰；当我们说heavy traffic是表示交通拥堵。此外，非常重要的一点是注意to, in , on , at ,from等等和其词的搭配使用,因为在某种程度上，它们能给我们关于选择项的提示。如：my _ for her moved her . (attitude ; love),二、 选词填空解题步骤和技巧,(2)理清复杂句式或上下文的逻辑结构，进行解题,大家需要关注形式上的逻辑关系和意义上逻辑关系。所谓形式上的逻辑关系就是我们通常讲的因果，让步，递进等；而意义上的逻辑关系就是以语篇表达的意思为线索，前后文中，意义上存在那些关系。比如说，描述一个人的心情的变化，心情好时，应该使用的是积极词汇，而心情不好时则使用消极词汇。当然，形式和意思之间存在紧密联系，不能割裂开来。,二、 选词填空解题步骤和技巧,三、 真题演练,A) appealingB) averageC) contributingD) dramaticE) frequently.F) impactG) line,H) maintainI) meltedJ) persistK) rangingL) recentlyM) resolvedN) sensibleO) shock,2014年6月份真题选词填空,A) appealingv.B) average adj. n.C) contributingv.D) dramaticadj.E) frequently adv.F) impactv. n.G) line n. v.,H) maintain v.I) melted v.J) persist v.K) ranging v.L) recently adv.M) resolved v.N) sensible adj.O) shock v. n.,2014年6月份真题选词填空,标注词性,Global warming is a trend toward warmer conditions around the world.
