最難題之
推斷題
TPO7 The Geologic History Of The Mediterranean
Paragraph 3: With question such as these clearly before them, the scientists aboard the Glomar Challenger processed to the Mediterranean to search for the answers. On August 23, 1970, they recovered asample. The sample consisted of pebbles of hardened sediment that had once been soft, deep-seamud, as well as granules of gypsum and fragments of volcanic rock. Not a single pebble was found that might have indicated that the pebbles came from thenearbycontinent. In the days following,samples of solid gypsum were repeatedly brought ondeckas drillingoperationspenetrated the seafloor. Furthermore, the gypsum was found to possess peculiarities of composition and structure that suggested it had formed on desert flats. Sediment above and below the gypsum layer contained tinymarinefossils, indicating open-ocean conditions. As they drilled into the central and deepest part of the Mediterraneanbasin, the scientists took solid, shiny, crystalline salt from the core barrel. Interbedded with the salt were thinlayersof what appeared to be windblown silt.
Which of the following can be inferred from paragraph 3 about the solid gypsum layer?
○It did not contain anymarinefossil.
○It had formed in open-ocean conditions.
○It had once been soft, deep-seamud.
○It contained sediment fromnearbydeserts.
開始做這道題僵控，我們可以首先按照傳統(tǒng)的思路回原文定位關(guān)于含有g(shù)ypsum layer這個關(guān)鍵詞的信息（原文高亮處）香到，也就是用于推理的那句話，然后就可以研讀這句話了。這句話的意思是“石膏層上下的沉積物中包含了微小的海洋生物化石悠就，說明了這是開放性的海洋環(huán)境千绪。”進行到這里梗脾，有的同學(xué)可能就沒有思路了荸型，根據(jù)這句話能推斷出什么結(jié)論呢？再觀察一下四個選項炸茧，更是跟原文相關(guān)度不太大瑞妇，于是便回原文繼續(xù)尋找可靠信息，懷疑自己是否是定位定錯了梭冠。
其實辕狰，這道題屬于一個特殊類——“取非”類推理】啬“取非”的意思是說從事物的相反面去思考并推斷事物本身有什么樣的特征柳琢。比如，“19世紀為蠟燭產(chǎn)業(yè)帶來一系列新發(fā)明润脸，從而使蠟燭的供給范圍覆蓋所有人∷ィ”那么毙驯，從這句話你能推斷出什么來呢？不言而喻吧灾测，自然是“19世紀以前蠟燭的供給是不能覆蓋所有人的”爆价。我們剛剛講的是涉及時間的“取非”推理，那么媳搪，涉及地點的“取非”推理大家是否能夠理解呢铭段？比如“這個地區(qū)以外的其他地方都有自來水”，你能否推斷出這個結(jié)論——這個區(qū)沒有自來水秦爆。如果可以序愚，那么恭喜你，你已經(jīng)理解了“取非類推理”等限。
現(xiàn)在我們回到上面這道推斷題爸吮，原文是“石膏層上下的沉積物中包含了微小的海洋生物化石，說明了這是開放性的海洋環(huán)境”望门。如果我們采用取非類推理方法形娇，很明顯，這句話涉及的是地點類的取非推理筹误。很簡單桐早，根據(jù)“石膏層的上下沉積物有海洋生物化石”，經(jīng)過反向思考，可以得出結(jié)論——石膏層本身沒有海洋生物化石哄酝。也就是選擇A項友存。
通過這道題，大家清楚了什么是取非類推理了嗎炫七？涉及時間的取非類推理和涉及地點的取非類推理大家都理解了嗎爬立？這類考題在真正的托福考試中也是頻頻出現(xiàn)万哪，希望各位小親足夠重視哦侠驯！
