托福閱讀否定事實(shí)信息題之虛假信息套路
一、自相矛盾
第一種情況是選項(xiàng)信息與原文相矛盾，錯(cuò)誤表述文中的信息或觀點(diǎn)。例如下題：
According to paragraph 6, all of the following statements aretrue of plants in the alpine zone EXCEPT：
○ Because they are low, they are less exposed to strong winds.
○ Because they are low, the winter snow cover gives them moreprotection from the extreme cold.
○ In the equatorial mountains, they tend to be lower than inmountains elsewhere.
○ Their low growth form keeps them closer to the ground, where thereis more heat than further up.
這道題的選項(xiàng)1改寫原文“… avoid theworst rigors of high winds…”；選項(xiàng)2對(duì)應(yīng)原文“…take advantage of the insulation provided by a winter snow cover”；選項(xiàng)4對(duì)應(yīng)原文“…make use of the higher temperaturesimmediately adjacent to the ground surface”；選項(xiàng)3中的“l(fā)ower”與原文之中“the low growth form is lessprevalent”相矛盾，因此該選項(xiàng)為虛假信息，選作本題的答案。
二、無中生有
第二種情況是選項(xiàng)信息在原文中沒有被提及。同學(xué)們可以比較容易地辨別出在原文中完全沒有提到的選項(xiàng)，但大家務(wù)必注意此類出題方式經(jīng)常會(huì)使點(diǎn)小心機(jī)，也就是選項(xiàng)的部分信息是對(duì)原文信息的重復(fù)，但是另一部分卻出現(xiàn)了新概念或腦補(bǔ)了新信息。例如：
PASSAGE EXCERPT： “The causes of this population rebound are consequences of otherhuman actions. First, the major predators of deer---wolves, cougar, andlynx--have been greatly reduced in numbers. Second, conservation has beeninsured by limiting times for and types of hunting. But the most profoundreason for the restoration of high population numbers has been the gate of theforests. Great tracts of lowland country deforested by logging, fire, or bothhave become ideal feeding grounds of deer. ”(TPO4： Deer Populations ofthe Puget Sound)
Which of the following is NOT mentioned in paragraph 5 as a factor that has increased deerpopulations？
○ A reduction in thenumber of predators
○ Restrictions on hunting
○ The effects of loggingand fire
○ Laws that protectedfeeding grounds of deer
選項(xiàng)1與原文“First, the majorpredators of deer---wolves, cougar, and lynx--have been greatly reduced innumbers”相對(duì)應(yīng)；選項(xiàng)2對(duì)應(yīng)原文“Second, conservationhas been insured by limiting times for and types of hunting”；選項(xiàng)3對(duì)應(yīng)原文“Great tracts of lowland countrydeforested by logging, fire”；選項(xiàng)4中的后半部分信息“feeding grounds of deer”是對(duì)原文 “… or both havebecome ideal feeding grounds of deer”中的原詞重復(fù)，但是選項(xiàng)前半部分新添加了原文沒有的信息“l(fā)aws that protected”，這仍然屬于無中生有的虛假信息，因此這道題應(yīng)該選擇后一個(gè)選項(xiàng)。
三、答非所問
后一種情況是需要大家特別注意的，即答非所問。選項(xiàng)可能重復(fù)文章中的信息，且沒有添加原文不存在的信息，然而它卻并沒有回答問題，因此仍然屬于虛假信息的范疇。例如：
PASSAGE EXCERPT：“Thesame thing happens to this day, though on a smaller scale, wherever asediment-laden river or stream emerges from a mountain valley ontorelatively flat land, dropping its load as the current slows： the waterusually spreads out fanwise, depositing the sediment in the form of a smooth,fan-shaped slope. Sediments are also dropped where a river slows on entering alake or the sea, the deposited sediments are on a lake floor or the seafloorat first……”(TPO1： GROUNDWATER)
All of the following are mentioned in paragraph 3 as places thatsediment-laden rivers can deposit their sediments EXCEPT
○ A mountain valley
○ Flat land
○ A lake floor
○ The seafloor
在做這道題的時(shí)候我們很焦灼地發(fā)現(xiàn)每一個(gè)選項(xiàng)都在原文中出現(xiàn)了(下劃線部分)，而且都沒有添加任何原文不存在的新信息。此時(shí)一定要冷靜，將選項(xiàng)與題干進(jìn)行核對(duì)。題目中問的是河流所攜帶的砂石會(huì)在什么地方沉淀，而原文“wherever a sediment-laden river or stream emerges from a mountainvalley onto relatively flat land, dropping its load as the currentslows ”表明水流從mountain valley 流出，流至相對(duì)平坦的地面時(shí)水流速度減慢從而逐漸沉淀砂石。當(dāng)我們理解這句話就會(huì)知道m(xù)ountain valley是水流出的地方而不是sediments沉淀的地方，也就是說選項(xiàng)1并不是針對(duì)題目的正確信息，因此它是被“EXCEPT”的對(duì)象，答案為選項(xiàng)1。
總結(jié)一下，選項(xiàng)中的虛假信息可能以自相矛盾、無中生有、答非所問的方式出現(xiàn)。這類虛假信息正是否定事實(shí)信息類題目的正確答案，而那些能夠在原文中找到對(duì)應(yīng)的選項(xiàng)統(tǒng)統(tǒng)都不選。
