下面我們以2013年考研英語真題中里出現(xiàn)的同義替換簡要跟大家來分享下，希望在以后的閱讀過程中注意此類選項和原文做對比, 以提高做題效率。
Text1 是一篇講述如何在對話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.
答題要點：既然是細節(jié)題,并且出現(xiàn)在第一道,那么應該正確答案理應出現(xiàn)在文章前面段落,并且很可能就是第一段.正確選項和原文之間并非出現(xiàn)詞匯的同義替換, 而是換了句型.
2：The joke about doctors implies that, in the eyes of nurses, they are________.
正確答案B：veryconscious of their godlike role
原文復現(xiàn)："Who is that?" the newarrival asked St. Peter. "Oh, that's God," came the reply, "butsometimes he thinks he's a doctor."
答題要點：這個題目難度較大, 但是解本題的時候, 除了找到此同義替換局外, 還有一點是關鍵的, 那就是這個例子出現(xiàn)的背景, 那就是護士對醫(yī)生有著一致的看法和觀點, 并且絕對不是一種好的評價, 所以才會拿來開玩笑. 所以再結合原文, 應該推斷, B為正確選項.說明醫(yī)生很在乎自己上帝般的角色God再次出現(xiàn)。
3： It can be inferred from the text that public services ________.
正確答案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.
答題要點：the Post Office or the telephonesystem與public services屬于上下義的關系，因此一定程度上屬于同義替換, 并且laughing stock與scapegoats如果仔細看這段文字的話, 也會發(fā)現(xiàn), 其實就是同義的表達而已.
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.
答題要點：先定位, 然后再來分析發(fā)現(xiàn)原文中nature, casual, off-the-cuff，relaxed,unforced全都是答案中casually的同義詞, 如此之多, 完全可以判定正確選項D
Text2
1: Human ingenuity was initially demonstrated in________.
正確答案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.
解題要點：本題的難度較小, 很容易辨析, 在原文與選項的對比之后發(fā)現(xiàn)tools 再次出現(xiàn)，difficult, dangerous是dangerous, boring,burdensome, or just plain nasty的同義替換, 也就是換個方式把原文的意思重新表達一次, 很明顯為正確選項.
2: The word "gizmos" (line 1, paragraph 2)most probably means ________.
正確答案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.
解題要點：從題型來看, 這屬于典型的詞匯題, 而詞匯題的做題關鍵則是在原文的上下文中找出相應的近義詞, 同義詞和反義詞之類, 也可以使同義表達.從后面定語從句來看，重點是remove human labor. 再從后面的幾個例子中，factory,banking, subway train幾個東西都是工具，得出答案。
3：題：According to the text, what is beyond man's ability now is to designa robot that can __
正確答案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."
答題要點：reliably interact with a dynamicworld是文章中的respond independently to a changing world同義轉化，并且題目中也有類似的同義替換, 如beyond man’s ability 等同于原文中的 can not yet give…
4：Besides reducing human labor, robots can also ________.
正確答案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…
答題要點：同義替換, with human intervention替換了文中with less human supervision.
比其他一些題目更難的地方在于, 這句話無論是原文還是正確選項都有個前提, 所以必須考慮進來, 如果不考慮前提,很有可能出現(xiàn)斷章取義, 導致錯選了A, make a fewdecision for themselves.
