大学英语四级阅读:选词填空技巧汇总 选词填空的考察形式 一篇280词左右的文章,文章中挖出10个空,并统一给出A-O 15个备选答案。选词填空区别于完形填空,有更大的解题难度,原因在于: 1. 完形填空每题都是四选一,选词填空第一题要十五选一,就算用到排除法,最后一题也要六选一,而且在十五个选项中还有五个根本不会用到,难度加大; 2. 完形填空每题的四个选项都是统一的词性,只需要辨析词义、搭配就基本可以作答,而选词填空的十五个选项有多个词性,解题时需要同时判断词性和词义,难度加大; 3. 完形填空每题的四个选项往往都是统一时态,统一形式,而在选词填空中会涉及选项的动词时态、第三人称单数形式、被动主动语态,名词的单复数等的辨析,难度加大。 针对选词填空的解题方法分为三步 1. 预览选项,了解词义并把选项分为四大类词性:名词n,动词v,形容词a,副词ad,在每个选项后作词性的简要标记; 2. 精读全文开头,把握文章主题,并以三个空或一个段落为一个单位,利用前后文判 断每空的词性; 3. 把对应词性的选项逐一带回原文,含义通顺,时态、主谓搭配一致的为正确选项。 四级考试的常用后缀在判断选项词性时可以有一定帮助作用。在根据前后文判断每空的词性时,一些经常考察的形式如下: 名词:通常来说,冠词(如a,an,the)、形容词、介词后面搭配名词,即"a/an/the/adj./prep. + n。", 举例说明:Education soon became a _____. 冠词a后面加可数名词的单数形式,正确答案是nightmare,这句话的意思是"教育很快成了一种噩梦。" As the trade winds lessen in _____, the ocean temperatures rise causing the Peru current flowing in from the east to warm up by as much as 5 degrees. (06-6) 介词in后面加名词,正确答案是strength,这句话的意思是"当信风强度减弱的时候,海洋温度上升,导致从东部流入的秘鲁洋流上升了5摄氏度之多。"较难的一个例子:Husbands and children now do some of these jobs, a ____ that has changed the target market for many products. (06-12) 这里可以用两种判断方法来判断横线处所填词的词性。第一种方法,用句子结构来判断,前面一句话,husbands and children now do some of these jobs,这是一个完整的句子,主语husbands and children,谓语动词do,宾语some of these jobs;后面的that 引导的是一个同位语从句,它所修饰的中心词就是a后面需要填的词,而定语从句的中心词是名词,所以横线处应填一个名词。第二种方法,根据刚才所说的"a + 名词"的语法规则来判断,横线处应该填一个名词,而且是一个可数名词的单数形式。正确答案是situation。这句话的意思是"丈夫和孩子现在也做一些这样的工作了,这种情况就改变了许多产品的目标市场。" 动词:动词的考点很多,我们来看其中三种: 1. 主语后缺谓语动词。举例说明:He ____ from his teachers, came home in tears and thought about dropping out. 在这句话里,主语是he,本来后面应该有一个动词作谓语,但是这里没有动词,而是在横线后面出现了一个介词短语from his teachers,这样这句话就缺少谓语动词,所以横线上应该填一个动词。正确答案是hid,这句话的意思是"他不愿见老师,

新视野大学英语4选词填空答案及翻译 一 Have you ever known anyone famous? If so, you may have found that the y are remarkably similar to the rest of us. You may have even heard them object to people saying there is anything different about them. “I’m really just a normal guy,”protests an actor who has recently rocketed into the spotlight. There is, of course, usually a brief period whe n they actually start to believe they are as great as their worshipping fans suggest. They start to wear fancy clothes and talk as if everyone should hear what they have to say. This period, however, does not often last long . They fall back to reality as fast as they had originally risen above it all. What will it feel like to soar to such altitude and look down like an eagl e from up high on everyone else? And what will it feel like to have flown so high only to wake from your dream and realize you are only human? Some only see the cruelty in losing something they had gained. They often make desperate attempts to regain what they lost. Often these efforts result in even greater pain. Some become bankrupt financially and emotionally. The only real winners are those who are happ y to be back on the ground with the rest of us. 你了解名人吗?如果是这样,你可能发现他们与我们身边其余的人非常地相似。甚至,你可能已经听到他们反对的人说有什么不同。“我真的只是一个普通人,”一个最近已经飙升到了聚光灯下的演员抗议说。
