託福閱讀推理題解析
推理題在託福閱讀中經常會出現，爲了幫助大家備考，提高託福閱讀分數，下面小編給大家帶來託福閱讀推理題解析，望喜歡!
託福閱讀推理題解析
推理題的標誌是在題幹中出現infer/imply/suggest/indicate/most likely 這樣的詞彙，它和細節題屬於同源題目，都需要定位並且根據文中信息來選擇答案。與細節題不同的是，推理題在找到原文中定位點之後考察的是學生對於文中信息的總結概括，或者反向推理的能力。
推理題的兩大分類：有共性的推理題和無共性的推理題。這裏所謂的有共性推理題就是說題幹中有和原文內容相同的關鍵詞(也叫線索)。根據關鍵詞回原文定位，然後進行推理。一般來說，大多數的推理題都屬於這類題目。對於無共性的推理題，也就是題幹中無線索，一般使用排除法，即根據各個選項的關鍵詞回原文定位，通過排除法得出正確答案。返回原文找信息點，採用排除法是解決這兩類題型解決的共同策略。
推理題大概有三個解題思路：一般對比推理、時間對比推理、集合概念推理。一般對比推理：根據兩個事情的對比特徵，問其中一個事物的特徵，只要將與之形成對比的另外一個事情的特徵否定掉就可以。時間對比推理：在這種推理中，一般有兩個形成對比的時間段，它們所具有的特徵一般相反。當題幹問一個時間段的特徵時，只要將與之相反的時間段的特徵否定掉就可以了。集合概念推理 ：一個大的集合的兩個方面形成對比，兩者之間存在着互補性關係，也就是一個的增加意味着另一個的減少。反之，相同。
在這裏我們先來看一個例子：
Passage：…The nineteenth century brought with it a burst of new discoveries and inventions that revolutionized the candle industry and made lighting available to all. In the early-to-mid-nineteenth century， a process was developed to refine tallow (fat from animals) with alkali and sulfuric acid. The result was a product called stearin. Stearin is harder and burns longer than unrefined tallow. This breakthrough meant that it was possible to make tallow candles that would not produce the usual smoke and rancid odor. Stearins were also derived from palm oils， so vegetable waxes as well as animal fats could be used to make candles…
Which of the following can be inferred from paragraph 1 about candles before the nineteenth century?
did not smoke when they were burned.
produced a pleasant odor as they burned.
were not available to all.
contained sulfuric acid.
正確答案是C.這一段的第一句就告訴我們：19世紀的一些新發明和發現也對蠟燭工業產生了一次巨大的革命，這次革命使得所有的人都使用上了照明。從這句話中我們可以得到兩層信息：19世紀蠟燭工業有了一次革命性的變化;在沒有這次變革之前，也就是在19世紀以前，照明並不是所有人都能使用的。因爲作者在談論的是蠟燭的變革，所以這裏所說的“lighting照明”一定是與蠟燭有關的照明，其實也就是告訴我們19世紀以前並不是所有人都能夠使用到蠟燭帶來的照明，這一推論出的信息正好與選項C吻合。文章第一句同時也是一個時間的分水嶺，告訴我們19世紀蠟燭工業的變革是怎麼樣的。“在19世紀早期到中期，蠟燭處理工藝使用alkali 和 sulfuric acid 來提煉 tallow，提煉後的產品就是 stearin，stearin 比未經提煉的tallow堅硬而且燃燒得更久。這一巨大的變化意味着製造出不產生煙和rancid味道的蠟燭是可能的。”在這裏的一個關鍵詞是 rancid，意思是(油脂食物，其味道、氣味)不新鮮的;腐臭的;正好與選項b的pleasant odor相反。19世紀前的蠟燭產生usualsmoke(經常有煙)，這與選項a相反。Sulfuric acid是19世紀用來處理fallow的材料，在19世紀以前是沒有使用的，這與選項d相反。
解答這裏題目時要注意這些關鍵信息點：日期和數字、關鍵詞： 表示多少的副詞: many , some, much of, several , a few ,most …;情態動詞：may, can , could…;表示過去的：used to be , was, were , at one time, previously ;表示不是唯一的： not only ,not exclusively等。
在此，我們在來看一道例題：
It should be obvious that cetaceans-whales , porpoises, and dolphins-are mammals. They breathe through lungs, not through gills, and give birth to live young. Their streamlined bodies, the absence of hind legs, and the presence of a fluke3 and blowhole4 cannot disguise their affinities with land-dwelling mammals. However, unlike the cases of sea otters and pinnipeds (seals, sea lions, and walruses, whose limbs are functional both on land and at sea), it is not easy to envision what the first whales looked like. Extinct but, already fully marine cetaceans are known from the fossil record. How was the gap between a walking mammal and a swimming whale bridged? Missing until recently were fossils clearly intermediate, or transitional, between land mammals and cetaceans.
Which of the following can be inferred from paragraph 1 about early sea otters?
a. It is not difficult to imagine what they looked like
e were great numbers of them.
c. They lived in the sea only.
did not leave many fossil remains.
首先我們來對題目的出題範圍進行定位，題乾的blowhole可以作爲定位詞彙，定位到原文的第四句話：“However, unlike the cases of sea otters and pinnipeds (seals, sea lions, and walruses, whose limbs are functional both on land and at sea), it is not easy to envision what the first whales looked like.” 在這句話裏交代了“unlike the casess of sea otters”，即與sea otters 不一樣的是，whales 的陳述是：it is not easy to envision what the first whales looked like. 即，不容易看出第一頭鯨長什麼樣子。而sea ottter 是和鯨魚相反，所以選擇A選項，即不難看出第一頭sea otter 長什麼樣子。所以實際上，這種題目雖然叫做推理題，但是並不需要同學們在做題的時候推的過遠，基本考察的還是對原文信息概括和總結的能力。
提高託福閱讀答對率有技巧
一、新託福閱讀的新題型重點考察句子間的關係
在託福閱讀中有那麼一個段落，其中有4 個框框，他代表你在題幹中的那句話可以拖入這個裏面來，做題的方法是：第一步一定要優先閱讀題幹中要被拖入到原文的那句話。第二步找要被代入原文那句話當中的關鍵字和要點。因爲我們知道，如果要把一句話代入到原文當中，這句話肯定和原文有很強的關聯性。
然後我們找的是要被代入原文那句話中的關聯詞，這有很多，比方說一旦看到"因爲"，前面講的就可能是原因，因爲這個結果後面有一個情況;再比如你看到THUS，通常表示結果，那麼正確選項在第一個空和第二個空的可能性不是很大，在第三個空和第四個空的可能性比較大，因爲它表示結果，基本都在比較靠後的位置;比如我們看到in contrast，跟前面正好是相反的，所以說這些關鍵詞特別重要，從一定意義上來講是我們做這種題型成敗的關鍵。
我們要找邏輯關係，你要代入這句話的話，跟前面或者後面的話肯定有一種邏輯關係在裏面，到底前後是轉折還是遞進還是表示結果還是什麼樣的關係，這是我們的情況。一般來說，多數中國同學做這個題還是比較容易的，我建議大家在備考的時候大量練習此類題目的做法。
二、多選題的關鍵在於題幹
iBT的聽力和閱讀的多選題應該如何把握?這也確實是中國同學比較容易錯的一個地方，新託福iBT中的多選題是這樣的，即一部分題型，每道題當中都有幾個選項是正確選項，也就是我們說的多選題。比如說，閱讀題最後一道題一般都是多選題，多選題分兩類，一類叫圖表題，給你一個圖表，讓你6選3或者 8選4。第二類叫文章內容小節題，文章內容概述題，什麼意思呢?先給你一句話，這句話就是這篇文章的中心思想，請問下面哪幾個選項中反映了這篇文章的中心思想。
這樣的話，這個題目是我們的第二個問法，這是閱讀中我們最常見的兩種多選題，這種題同學們不要有畏懼心理，因爲這類題目分值也比較高，一般是2 分或3分。我們即使答錯一個空，3分題還會拿到兩分，不會給你扣掉所有的分。
第二，這個問題是基於你之前問題的答案的基礎上，當你把之前其他的問題都答完了，你整個的這篇文章讀的也很好了，再做這個題的話，基本上問題不大了。只要別錯太多，這種題多少都會有分的。第三，這類題目的數量比較少。所以我們做這個題要特別的細心，做這個題的關鍵在於對這道題題幹中的那句話的理解，因爲這句話就是文章的概述，基本上下面的答案都是符合這句話的，或和這句話有關聯點的，跟這句話扯得太遠的一般就是錯誤選項，所以要求我們特別細心，越細心越好。
託福閱讀真題1
In 1972, a century after the first national park in the United States was established at Yellowstone, legislation was passed to create the National Marine Sanctuaries Program. The intent of this legislation was to provide protection to selected coastal habitats similar to that existing for land areas designated as national parks. The designation of an area's marine sanctuary indicates that it is a protected area, just as a national park is. People are permitted to visit and observe there, but living organisms and their environments may not be harmed or removed.
The National Marine Sanctuaries Program is administered by the National Oceanic and Atmospheric Administration, a branch of the United States Department of Commerce. Initially, 70 sites were proposed as candidates for sanctuary status. Two and a half decades later, only fifteen sanctuaries had been designated, with half of these established after 1978. They range in size from the very small (less than 1 square kilometer) Fagatele Bay National Marine Sanctuary in American Samoa to the Monterey Bay National Marine Sanctuary in California, extending over 15,744 square kilometers.
The National Marine Sanctuaries Program is a crucial part of new management practices in which whole communities of species, and not just individual species, are offered some degree of protection from habitat degradation and overexploitation. Only in this way can a reasonable degree of marine species diversity be maintained in a setting that also maintains the natural interrelationships that exist among these species.
Several other types of marine protected areas exist in the United States and other countries. The National Estuarine Research Reserve System, managed by the United States government, includes 23 designated and protected estuaries. Outside the United States, marine protected-area programs exist as marine parks, reserves, and preserves. Over 100 designated areas exist around the periphery of the Caribbean Sea. Others range from the well-known Australian Great Barrier Reef Marine Park to lesser-known parks in countries such as Thailand and Indonesia, where tourism is placing growing pressures on fragile coral reef systems. As state, national, and international agencies come to recognize the importance of conserving marine biodiversity, marine projected areas. whether as sanctuaries, parks, or estuarine reserves, will play an increasingly important role in preserving that diversity. ?

PASSAGE 51 BCADB DADD
託福閱讀真題2
In the early 1800's, over 80 percent of the United States labor force was engaged in agriculture. Sophisticated technology and machinery were virtually nonexistent. People who lived in the cities and were not directly involved in trade often participated in small cottage industries making handcrafted goods. Others cured meats, ran bakeries, or otherwise produced needed goods and commodities. Blacksmiths, silversmiths, candle makers, and other artisans worked in their homes or barns, relying on help of family members or apprentices.
Perhaps no single phenomenon brought more widespread and lasting change to the United States society than the rise of industrialization. Industrial growth hinged on several economic factors. First, industry requires an abundance of natural resources, especially coal, iron ore, water, petroleum, and timber — all readily available on the North American continent. Second, factories demand a large labor supply. Between the 1870's and the First World War (1914-1918), approximately 23 million immigrants streamed to the United States, settled in cities, and went to work in factories and mines. They also helped build the vast network of canals and railroads that crisscrossed the continent and linked important trade centers essential to industrial growth.
Factories also offered a reprieve from the backbreaking work and financial unpredictability associated with farming. Many adults, poor and disillusioned with farm life, were lured to the cities by promises of steady employment, regular paychecks, increased access to goods and services, and expanded social opportunities. Others were pushed there when new technologies made their labor cheap or expendable; inventions such as steel plows and mechanized harvesters allowed one farmhand to perform work that previously had required several, thus making farming capital-intensive rather than labor-intensive.
The United States economy underwent a massive transition and the nature of work was permanently altered. Whereas cottage industries relied on a few highly skilled craft workers who slowly and carefully converted raw materials into finished products from start to finish, factories relied on specialization. While factory work was less creative and more monotonous, it was also more efficient and allowed mass production of goods at less expense.

occurred in the United States before 1914?
(A) The availability of natural resources found only in the United States
(B) The decrease in number of farms resulting from technological advances
(C) The replacement of canals and railroads by other forms of transportation
(D) The availability of a large immigrant work force

(B) Mechanized farming required more capital and fewer laborers.
(C) The new inventions were not helpful for all farming activities.
