1、托福阅读备考之事实信息题讲解 回顾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 /related to X? 例:Ac
2、cording 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: 1). 该题型是就某段话当中的某个细微
3、环节信息(即提问方式1中的X)进行提问。 2). 该题型可以围绕该细微环节信息的不同方面进行提问,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,无需考生进行文本的隐含意推理。 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, 那么定位词则是位于介词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,因为定位词越多相对定位的位置也会越。)
4、 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,定位词应当是位于介词of后面的challen
5、ge toresearchers。至于后面的playbehavior就不须要了,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出名词部分,考生们可以看到两组名词:CatholicChurch和MechanicalClocks, 并且这两组词都是我们所须要的定位词。 Para
6、graph5 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探讨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找寻答案。 Step 2: 通过题干中定位词回原文进行定位。 留意:在定位的过程中考生们可能会遇到以下2个问题:
7、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,但假如是一般名词则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 subpopulations. Phy
8、sical 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 between the subpo
9、pulations, 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.This route to spec
10、iationis 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。 例2:定位词为非原文原词的
11、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 literature, and the r
12、easons 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 animal's adulthood. (TPO30 Role of Play in Development) According toparagraph 2, which of the following pr
13、esents 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 transition from y
14、outh 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的同义替换形式difficult, 因此该句即是我们所须要的定位句。 问题2:定位词在原文中出现不止一次。 Paragraph 7: Occasionally, a sequence offossil-rich layers of
15、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
16、 of 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 du
17、ring 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 histor
18、y O 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, 然后回读原文进行定位,考生们会发觉这两组定位词在原文中分别出现2次。因此,考生们须要定位的范围变大,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
19、的是由新的几套TPO中的例题显示这种类型的题目正在变多,所以朗阁海外考试探讨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: 比较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,而选项相对比较简短,所以考生们肯定要学会从长难句中截取你所须要的能回答问题的部分。简洁点说就是比如题干中问你why.;那么,此时考生们在分析原文定位句时应当重点看because这种能够说明的部分。 2). 考生们在比较定位句与选项时切忌不能随意推理,只须要把握文本的字面意思即可。 例1: Paragraph 3: To what extent
20、competition 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
21、 or disappearance 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 l
22、aw of competitive 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 oc
23、cupy exactly 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 de
