下面我们以2013年考研英语真题中里出现的同义替换简要跟大家来分享下，希望在以后的阅读过程中注意此类选项和原文做对比, 以提高做题效率。
    
    Text1 是一篇讲述如何在对话中有效使用幽默的文章
    
    1：To make your humor work, you should ________.
    
    答案C：addressdifferent problems to different people
    
    定位原文：Depending on whom you areaddressing, the problems will be different.
    
    答题要点：既然是细节题,并且出现在第一道,那么应该正确答案理应出现在文章前面段落,并且很可能就是第一段.正确选项和原文之间并非出现词汇的同义替换, 而是换了句型.
    
    2：The joke about doctors implies that, in the eyes of nurses, they are________.
    
    正确答案B：veryconscious of their godlike role
    
    原文复现："Who is that?" the newarrival asked St. Peter. "Oh, that's God," came the reply, "butsometimes he thinks he's a doctor."
    
    答题要点：这个题目难度较大, 但是解本题的时候, 除了找到此同义替换局外, 还有一点是关键的, 那就是这个例子出现的背景, 那就是护士对医生有着一致的看法和观点, 并且绝对不是一种好的评价, 所以才会拿来开玩笑. 所以再结合原文, 应该推断, B为正确选项.说明医生很在乎自己上帝般的角色God再次出现。
    
    3： It can be inferred from the text that public services ________.
    
    正确答案D：haveoften been the laughing stock
    
    原文定位：You will be on safer ground ifyou stick to scapegoats like the Post Office or the telephone system.
    
    答题要点：the Post Office or the telephonesystem与public services属于上下义的关系，因此一定程度上属于同义替换, 并且laughing stock与scapegoats如果仔细看这段文字的话, 也会发现, 其实就是同义的表达而已.
    
    4：To achieve the desired result, humorous stories should be delivered________.
    
    答案D：ascasually as possible
    
    原文定位：If you feel awkward beinghumorous, you must practice so that it becomes more natural. Include a fewcasual and apparently off-the-cuff remarks which you can deliver in a relaxedand unforced manner.
    
    答题要点：先定位, 然后再来分析发现原文中nature, casual, off-the-cuff，relaxed,unforced全都是答案中casually的同义词, 如此之多, 完全可以判定正确选项D
    
    Text2
    
    1: Human ingenuity was initially demonstrated in________.
    
    正确答案C：theinvention of tools for difficult and dangerous work
    
    原文定位：Since the dawn of humaningenuity, people have devised ever more cunning tools to cope with work thatis dangerous, boring, burdensome, or just plain nasty.
    
    解题要点：本题的难度较小, 很容易辨析, 在原文与选项的对比之后发现tools 再次出现，difficult, dangerous是dangerous, boring,burdensome, or just plain nasty的同义替换, 也就是换个方式把原文的意思重新表达一次, 很明显为正确选项.
    
    2: The word "gizmos" (line 1, paragraph 2)most probably means ________.
    
    正确答案C：devices
    
    原文定位：As a result, the modern world isincreasingly populated by intelligent gizmos whose presence we barely noticebut whose universal existence has removed much human labor.
    
    解题要点：从题型来看, 这属于典型的词汇题, 而词汇题的做题关键则是在原文的上下文中找出相应的近义词, 同义词和反义词之类, 也可以使同义表达.从后面定语从句来看，重点是remove human labor. 再从后面的几个例子中，factory,banking, subway train几个东西都是工具，得出答案。
    
    3：题：According to the text, what is beyond man's ability now is to designa robot that can __
    
    正确答案D：respondindependently to a changing world
    
    原文定位："While we know how to tella robot to handle a specific error," says Dave Lavery, manager of arobotics program at NASA, "we can't yet give a robot enough 'common sense'to reliably interact with a dynamic world."
    
    答题要点：reliably interact with a dynamicworld是文章中的respond independently to a changing world同义转化，并且题目中也有类似的同义替换, 如beyond man’s ability 等同于原文中的 can not yet give…
    
    4：Besides reducing human labor, robots can also ________.
    
    正确答案B：dealwith some errors with human intervention
    
    原文定位：But if robots are to reach thenext stage of laborsaving utility, they will have to operate with less humansupervision and be able to make at least a few decisions for themselves — goalsthat pose a real challenge….while we know how to tell a robot to handle aspecific error…
    
    答题要点：同义替换, with human intervention替换了文中with less human supervision.
    
    比其他一些题目更难的地方在于, 这句话无论是原文还是正确选项都有个前提, 所以必须考虑进来, 如果不考虑前提,很有可能出现断章取义, 导致错选了A, make a fewdecision for themselves.
