托福阅读备考之事实信息题讲解

1、资料来源：来自本人网络整理！祝您工作顺利！托福阅读备考之事实信息题讲解 回忆托福阅读的全部题型，其中有2种题型占据的比例-“词汇题和“事实信息题，前者每一场考试大约考察10-12题左右，而后者大约也会考察12题左右。因此，从每一场考试的39-42题总量上来看，这两种题型就占据了半壁江山。从难度系数上来看事实信息题的难度明显高于词汇题。那么，今日笔者准备简洁谈一谈该题型的解决方法。 托福阅读备考之事实信息题讲解 1. 提问方式： accordingto paragraph which of the following statements is true of / concerned with

2、/related to x? 例：according toparagraph 1, what was true of the sahara region around 6,000 b.c.? (tpo 28 earlysaharan pastoralists) accordingto paragraph why / how / what.? 例：according to paragraph 1, why is playdifficult to define? (tpo 30 role of playin development) 分析：通过以上两种不同提问方式可以总结出该题型有以下几个特点：

3、1). 该题型是就某段话当中的某个详情信息(即提问方式1中的x)进展提问。 2). 该题型可以围绕该详情信息的不同方面进展提问，通过特别疑问词which;what; why; how可以看出。 3). 由于题干中未出现infer;suggest; indicate等字样，所以该题型旨在考察文本信息的字面含义，无需考生进展文本的隐含意推理。 2. 解题步骤： step 1: 读题干，找出定位词 留意：假如是提问方式1, 那么定位词那么是位于介词of/with/ to后面的信息。 假如是提问方式2, 那么定位词一般是名词，并且是非主题性的名词(当然定位词不肯定只能找一个，一般可以找2到3个，因为定

4、位词越多相对定位的位置也会越。) 例： accordingto paragraph 2, which of the following presents a particular challenge toresearchers who study play behavior in animals?(tpo30 role of play in development) 分析：通过提问方式类似于第1种提问方式，其实题干可以改写成whichof the following statements is true of the challenge to researchers who 因此，定位词应当是

5、位于介词of后面的challenge toresearchers。至于后面的playbehavior就不需要了，因为它属于通篇的主题词。 accordingto paragraph 4, how did the catholic church react to the introduction ofmechanical clocks? (tpo 30 the inventionof mechanical clock) 分析：通过提问方式属于第2种提问方式，因此考生们应当在题干中找知名词局部，考生们可以看到两组名词：catholicchurch和mechanicalclocks, 并且这两组词都

6、是我们所需要的定位词。 paragraph5 answers which of the following questions about mechanical clocks. (tpo 30 the invention of mechanical clock) 分析：通过题干找出题干中一疑似的定位词组mechanical clocks, 但是却发觉整篇文章都在争论mechanicalclocks。这种类型的提问方式是考生们怕看到的，因为定位词无效。此刻建议考生们可以反过来先读选项，然后依据选项中的定位词回读段落查找答案。 step 2: 通过题干中定位词回原文进展定位。 留意：在定位的过程中

7、考生们可能会遇到以下2个问题： 问题1：定位词在原文中可能是非原文原词(假如是专出名词一般在原文中就是原文原词，但假如是一般名词那么有可能是非原文原词)。 例1：定位词为原文原词的状况 paragraph 1: evolutionary biologists believe thatspeciation, the formation of a new species, often begins when some kind ofphysical barrier arises and divides a population of a single species intoseparate su

8、bpopulations. physical separation between subpopulations promotesthe formation of new species because once the members of one subpopulation canno longer mate with members of another subpopulation, they cannot exchangevariant genes that arise in one of the subpopulations. in the absences of geneflow

9、between the subpopulations, genetic differences between the groups beginto accumulate. eventually the subpopulations become so genetically distinctthat they cannot interbreed even if the physical barriers between them wereremoved. at this point the subpopulations have evolved into distinct species.t

10、his route to speciationis known as allopatry(“alio- means “different，and “patria means “homeland).(tpo31 speciationin geographically isolated populations) q: according to paragraph 1, allopatric speciation involveswhich of the following? 分析：此题干中的定位词为allopatric speciation, 为专出名词，在原文中为原文原词，即后一句话为定位句。

11、例2：定位词为非原文原词的状况 paragraph 2: playappears to be a developmental characteristic of animals with fairlysophisticated nervous systems, mainly birds and mammals. play has been studiedmost extensively in primates and canids (dogs). exactly why animals play isstill a matter debated in the research literatu

12、re, and the reasons may not bethe same for every species that plays. determining the functions of play is difficultbecause the functions may be long-term, with beneficial effects not showing upuntil the animals adulthood. (tpo30 role of play in development) according toparagraph 2, which of the foll

13、owing presents a particular challenge toresearchers who study play behavior in animals? o the delay between activities and the benefitsthe animal derives from them. o the difficulty in determining which animalspecies play and which do not. o the fact that for most animals, there is noclear transitio

14、n from youth to full adulthood. o the lack of research on the play behavior ofanimals other than canids and primates. 分析：此题干中的定位词为challenge researchers, 在原文中考生们无法找到这两个定位词，但是可以找到challenge的同义交换形式difficult, 因此该句即是我们所需要的定位句。 问题2：定位词在原文中出现不止一次。 paragraph 7: occasionally, a sequence offossil-rich layers o

15、f rock permits a comprehensive look at one type of organismover a long period of time. for example, peter sheldon s studies of trilobites, a now extinct marineanimal with a segmented body, offer a detailed glimpse into three million yearsof evolution in one marine environment. in that study, each of

16、 eight different trilobitespecies was observed to undergo a gradual change in the number of segments -typically an increase of one or two segments over the whole time interval. nosignificant discontinuous were observed, leading sheldon to conclude thatenvironmental conditions were quite stable durin

17、g the period he examined. (tpo30 the pace of evolutionary change) according toparagraph 7, peter sheldons studies demonstrated which of the following abouttrilobites? o they underwent gradual change over a longtime period o they experienced a number of discontinuoustransitions during their history o

18、 they remained unchanged during a long periodof environmental stability o they evolved in ways that cannot be countedfor by either of the two competing theories. 分析：通过题干找出定位词peter sheldon trilobites, 然后回读原文进展定位，考生们会发觉这两组定位词在原文中分别出现2次。因此，考生们需要定位的范围变大，难度由此也加大了。这种类型的事实信息题是考生们在考场上不情愿看到的一种，但是很不幸的是由新的几套tp

19、o中的例题显示这种类型的题目正在变多，所以朗阁海外考试讨论中心的专家请各位考生平常在练习时加大这种类型的考题的练习。 step3: 比拟定位句与选项的内容，选出语义接近的选项。 留意：1). 考生们所看到的定位句可能是一个特别长的句子，而选项相比照较简短，所以考生们肯定要学会从长难句中截取你所需要的能回答下列问题的局部。简洁点说就是比方题干中问你why.;那么，此时考生们在分析原文定位句时应当重点看because这种可以说明的局部。 2). 考生们在比拟定位句与选项时切忌不能随便推理，只需要把握文本的字面意思即可。 例1： paragraph 3: to what extent competi

20、tion determines the composition of acommunity and the density of particular species has been the source ofconsiderable controversy. the problem is that competition ordinarily cannot beobserved directly but must be inferred from the spread or increase of onespecies and the concurrent reduction or dis

21、appearance of another species. therussian biologist g. f. gause performed numerous two-species experimentsin the laboratory, in which one of the species became extinct when only asingle kind of resource was available. on the basis of these experiments and offield observations, the so-called law of c

22、ompetitive exclusion was formulated,according to which no two species can occupy the same niche. numerousseeming exceptions to this law have since been found, but they can usually beexplained as cases in which the two species, even though competing for a majorjoint resource, did not really occupy ex

23、actly the same niche. (tpo 29 competition) paragraph 3 supports the idea that gauses experiments were importantbecause they o provided a situation in whichcompetition could be removed from the interaction between two species o showed that previous ideasabout the extent to which competition determine

24、s the composition of a communitywere completely mistaken o helped establish thatcompetition will remove all but one species from any given ecological niche o offered evidence thatcompetition between species is minimal when there is an overabundance of asingle food source 解题步骤： 1). 读题干，找出定位词gauses ex

25、periments, 然后把握题目问的内容是有关于g的试验的importance。 2). 通过定位词回到原文进展定位，位于第三句话。但是第三句只提到了定位词之一，接下来的第四句中提到了由此形成了一个law, 可以对应题干中想问的importance。 3). 第3句和第4句两句定位句的大意为“当只有一种食物来源被供应时，两种物种中的一种会消亡。参照这些试验和观看就形成了竞争互斥规律-没有哪两种物种可以占据同样的生态圈，接下来扫瞄四个选项，发觉c选项大意吻合-确定了竞争将会移除其他全部的物种在任何一个生态圈里面。 例2： as railroad linesfanned out from chi

26、cago, farmers began to acquire open prairie land in illinois andthen iowa, putting the fertile, deep black soil into production. commercialagriculture transformed this remarkable treeless environment. to settlersaccustomed to eastern woodlands, the thousands of square miles of tall grasswere an awes

27、ome sight. indian grass, canada wild rye, and native big bluestemall grew higher than a person. because eastern plows could not penetrate thedensely tangled roots of prairie grass, the earliest settlers erected farmsalong the boundary separating the forest from the prairie. in 1837, however,john dee

28、re patented a sharp-cutting steel plow that sliced through the sodwithout soil sticking to the blade. cyrus mccormick refined a mechanical reaperthat harvested fourteen times more wheat with the same amount of labor. by the1850s mccormick was selling 1,000 reapers a year and could not keep up withde

29、mand, while deere turned out 10,000 plows annually. (tpo 33 railroads andcommercial agriculture in nineteenth-century united states) accordingto paragraph 5, the firstsettlersgenerally did not farm open prairie land because a.they could not plow it effectively with the tools that were available. b.p

30、rairie land was usually very expensive to buy. c.the soil along boundaries between the forest and the prairie was more fertile thanthe soil of the open prairie. d.the railroad lines had not yet reached the open prairie when the first settlersarrived. 解题步骤： 1).读题干，找出定位词settlers open prairie land, 并且抓

31、住题干问的重点是because 2).依据定位词定位到句和第三句这样的语义群，这样的语义群可以给我们供应一个大范围定位，然后接下来考生们在第四句里看到了because,所以第四句就是我们需要的定位点。 3).定位句的语义大约为“因为东部的耕种工具无法穿透这里的根部缠结在一起的草，因此，早期的定居者们将农场建立在了远离草原的边界地区。接下来扫瞄四个选项，只有a选项提到了因为耕作工具的缘由，所以选择a选项。 3. 总结： 1).此种题型必需要先阅读题干，摸清题干所问的详细内容，然后再读文章进展定位 2).此种题型既可以只考察某一个特定的定位句理解;同时也可以考察2-3个定位句范围的意群理解。但无论

32、怎样，考生不是漫无目的地搜寻，而是依据题干有目的性地查找答案。 托福阅读材料：如何延长友谊的“保质期 1.make time for friendships. nothing makes closeness fade away more than never talking to or seeing each other. while some bonds of friendship may be strong enough to span long silences, most arent. if you cherish a persons friendship, make time for
