托福閱讀看文章時(shí)哪些部分要詳讀?這6類(lèi)內(nèi)容請(qǐng)認(rèn)真看懂，今天小編給大家?guī)?lái)了托福閱讀看文章時(shí)哪些部分要詳讀，希望能夠幫助到大家，下面小編就和大家分享，來(lái)欣賞一下吧。
托福閱讀看文章時(shí)哪些部分要詳讀?這6類(lèi)內(nèi)容請(qǐng)認(rèn)真看懂
托福閱讀詳讀部分：重要的邏輯關(guān)系(relation)
很多考生在閱讀文章的時(shí)候只注意到了文章所闡述的重要內(nèi)容，但是忽略了信息之間的邏輯關(guān)系，因而對(duì)信息關(guān)聯(lián)理解不準(zhǔn)確(incorrect)，這也是一種嚴(yán)重的錯(cuò)誤(mistake)。因此，在閱讀過(guò)程中記錄下信息之間所產(chǎn)生的邏輯關(guān)系可以避免(avoid)考生丟失信息之間的關(guān)聯(lián)信息。
托福閱讀詳讀部分：主題段和主題句的關(guān)鍵詞(key words)
托福閱讀文章中的主題段和主題句都是參與搭建文章結(jié)構(gòu)的，因此記錄它們中的幾個(gè)關(guān)鍵詞對(duì)于把握全文的結(jié)構(gòu)非常重要。同時(shí)，文章中有很多的重要信息(information)也會(huì)包含在這部分內(nèi)容中。
托福閱讀詳讀部分：舉例主體
有的時(shí)候?yàn)榱苏f(shuō)明某些理論和觀點(diǎn)，文章中會(huì)出現(xiàn)大段的舉例文字。實(shí)際上(in fact)，TOEFL考試中考查這些例子具體內(nèi)容(specific content)的時(shí)候非常少，而更多的是考查作者使用這些例子的原因(reason)或它們所證明的觀點(diǎn)。因此，考生在快速筆記中只需要記錄下例子是什么就可以了，至于例子中所闡述的具體信息，可以適當(dāng)忽略(omit)。
托福閱讀詳讀部分：時(shí)間和數(shù)字(number)
一般來(lái)說(shuō)，出現(xiàn)時(shí)間概念的文章(essay)或段落通常和時(shí)間順序(order)有關(guān)，作者會(huì)用不同的時(shí)間點(diǎn)串出一條時(shí)間線索(clue)。而個(gè)別數(shù)字的出現(xiàn)則意味著這個(gè)數(shù)字所闡述概念的重要性是不容忽視的(ignored)，因此，除非文章中出現(xiàn)了數(shù)據(jù)堆積的現(xiàn)象(phenomenon)，考生都需要把數(shù)字記錄(record)下來(lái)。在記錄時(shí)間和數(shù)字時(shí)需要注意兩個(gè)問(wèn)題(question)，一是在記錄時(shí)間的同時(shí)要同步記錄下該時(shí)間點(diǎn)所發(fā)生事件的關(guān)鍵詞，二是無(wú)論文章中的時(shí)間和數(shù)字是什么形式(form)，考生在記錄的時(shí)候都一律記錄成阿拉伯?dāng)?shù)字，以便于之后做托福閱讀題時(shí)的查詢(xún)。
托福閱讀詳讀部分：人名、地名和專(zhuān)有名詞(proper noun)
這些概念在文章中出現(xiàn)的時(shí)候，一般都會(huì)出現(xiàn)大寫(xiě)字母或引號(hào)等標(biāo)記(sign)，非常有利于信息索引和定位。此外，當(dāng)提到這幾個(gè)具體的概念時(shí) (concept)，文章通常是在用這些概念說(shuō)明某個(gè)理論或者觀點(diǎn)(opinion)，因此記錄下這些概念對(duì)于理解相關(guān)理論和觀點(diǎn)可以起到一定的輔助作用。
托福閱讀詳讀部分：新概念和局部核心概念
所謂“新概念”是指當(dāng)考生讀到文章某個(gè)位置時(shí)，之前沒(méi)有出現(xiàn)過(guò)的概念。這種新概念的出現(xiàn)(appearance)，意味著已有的概念已經(jīng)不能說(shuō)明這里要闡述的問(wèn)題，所以，新概念的出現(xiàn)必然也意味著一個(gè)重要信息的出現(xiàn)。而“局部核心概念”是指在連續(xù)的幾個(gè)段落中集中闡述的主題概念，對(duì)于這種概念來(lái)說(shuō)，無(wú)論是作為觀點(diǎn)還是舉例大家都應(yīng)該注意(pay attention to)，因?yàn)樗@然是作為重點(diǎn)在文章中被強(qiáng)調(diào)的(emphasized)，也很可能是托福閱讀試題的關(guān)鍵。
托福閱讀備考之長(zhǎng)難句分析：二戰(zhàn)之后的加拿大
托福閱讀長(zhǎng)難句：二戰(zhàn)之后的加拿大
Basic to any understanding of Canada in the 20 years after the Second World War is the country's impressive population growth.
(倒裝結(jié)構(gòu)Basic to any understanding…is…)
要理解二戰(zhàn)之后20年中的加拿大，就必須了解該國(guó)驚人的人口增長(zhǎng)。
分句1：Basic to any understanding of Canada in the 20 years after the Second World War
分句2：is
分句3：the country's impressive population growth
分句1，2，3共同構(gòu)成倒裝句，正常的語(yǔ)序應(yīng)該是3，2，1，即：該句的正常語(yǔ)序是The country's impressive population growth is basic to any understanding of Canada in the 20 years after the Second World War.
本句是一個(gè)簡(jiǎn)單句，只不過(guò)使用了倒裝，謂語(yǔ)動(dòng)詞是is.
托福閱讀備考之事實(shí)信息題解析
1、提問(wèn)方式
Accordingto paragraph… which of the following statements is true of / concerned with /related to X?
例：According toparagraph 1, what was true of the Sahara region around 6,000 B.C.? (TPO 28 Early Saharan Pastoralists)
Accordingto paragraph… why / how / what….?
例：According to paragraph 1, why is playdifficult to define? (TPO30 Role of Play in Development)
分析：通過(guò)以上兩種不同提問(wèn)方式可以總結(jié)出該題型有以下幾個(gè)特點(diǎn)：
1). 該題型是就某段話(huà)當(dāng)中的某個(gè)細(xì)節(jié)信息(即提問(wèn)方式1中的X)進(jìn)行提問(wèn)。
2). 該題型可以圍繞該細(xì)節(jié)信息的不同方面進(jìn)行提問(wèn)，通過(guò)特殊疑問(wèn)詞which;what; why; how可以看出。
3). 由于題干中未出現(xiàn)infer;suggest; indicate等字樣，所以該題型旨在考察文本信息的字面含義，無(wú)需考生進(jìn)行文本的隱含意推理。
2、解題步驟
Step 1: 讀題干，找出定位詞
注意：如果是提問(wèn)方式1, 那么定位詞則是位于介詞of/with/ to后面的信息。
如果是提問(wèn)方式2, 那么定位詞一般是名詞，并且是非主題性的名詞(當(dāng)然定位詞不一定只能找一個(gè)，一般可以找2到3個(gè)，因?yàn)槎ㄎ辉~越多相對(duì)定位的位置也會(huì)越精確。)
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：通過(guò)提問(wèn)方式類(lèi)似于第1種提問(wèn)方式，其實(shí)題干可以改寫(xiě)成whichof the following statements is true of the challenge to researchers who… 因此，定位詞應(yīng)該是位于介詞of后面的challenge toresearchers。至于后面的playbehavior就不需要了，因?yàn)樗鼘儆谕ㄆ闹黝}詞。
Accordingto paragraph 4, how did the Catholic Church react to the introduction ofmechanical clocks? (TPO 30 The Inventionof Mechanical Clock)
分析：通過(guò)提問(wèn)方式屬于第2種提問(wèn)方式，因此考生們應(yīng)該在題干中找出名詞部分，考生們可以看到兩組名詞：CatholicChurch和MechanicalClocks, 并且這兩組詞都是我們所需要的定位詞。
Paragraph5 answers which of the following questions about mechanical clocks. (TPO 30 The Invention of Mechanical Clock)
分析：通過(guò)題干找出題干中唯一疑似的定位詞組Mechanical Clocks, 但是卻發(fā)現(xiàn)整篇文章都在討論MechanicalClocks。這種類(lèi)型的提問(wèn)方式是考生們最怕看到的，因?yàn)槎ㄎ辉~無(wú)效。此刻建議考生們可以反過(guò)來(lái)先讀選項(xiàng)，然后根據(jù)選項(xiàng)中的定位詞回讀段落尋找答案。
Step 2: 通過(guò)題干中定位詞回原文進(jìn)行定位。
注意：在定位的過(guò)程中考生們可能會(huì)遇到以下2個(gè)問(wèn)題：
問(wèn)題1：定位詞在原文中可能是非原文原詞(如果是專(zhuān)有名詞一般在原文中就是原文原詞，但如果是普通名詞則有可能是非原文原詞)。
例1：定位詞為原文原詞的情況
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. 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 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.This 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：此題干中的定位詞為allopatric speciation, 為專(zhuān)有名詞，在原文中為原文原詞，即最后一句話(huà)為定位句。
例2：定位詞為非原文原詞的情況
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 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 animal's adulthood. (TPO30 Role of Play in Development)
According toparagraph 2, which of the following 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 transition from youth to full adulthood.
O The lack of research on the play behavior ofanimals other than canids and primates.
分析：此題干中的定位詞為challenge & researchers, 在原文中考生們無(wú)法找到這兩個(gè)定位詞，但是可以找到challenge的同義替換形式difficult, 因此該句即是我們所需要的定位句。
問(wèn)題2：定位詞在原文中出現(xiàn)不止一次。
Paragraph 7: Occasionally, a sequence offossil-rich layers of 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 marine animal with a segmented body, offer a detailed glimpseinto three million years of evolution in one marine environment. In that study,each of eight different trilobite species was observed to undergo agradual change in the number of segments --- typically an increase of one ortwo segments over the whole time interval. No significant discontinuous wereobserved, leading Sheldon to conclude that environmental conditionswere quite stable during the period he examined. (TPO30 The Pace of Evolutionary Change)
According toparagraph 7, Peter Sheldon’s 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 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：通過(guò)題干找出定位詞Peter Sheldon & trilobites, 然后回讀原文進(jìn)行定位，考生們會(huì)發(fā)現(xiàn)這兩組定位詞在原文中分別出現(xiàn)2次。因此，考生們需要定位的范圍變大，難度由此也加大了。這種類(lèi)型的事實(shí)信息題是考生們?cè)诳紙?chǎng)上最不愿意看到的一種，但是很不幸的是由最新的幾套TPO中的例題顯示這種類(lèi)型的題目正在變多，所以朗閣海外考試研究中心的專(zhuān)家請(qǐng)各位考生平時(shí)在練習(xí)時(shí)加大這種類(lèi)型的考題的練習(xí)。
Step3: 比較定位句與選項(xiàng)的內(nèi)容，選出語(yǔ)義最接近的選項(xiàng)。
注意：
1). 考生們所看到的定位句可能是一個(gè)非常長(zhǎng)的句子，而選項(xiàng)相對(duì)比較簡(jiǎn)短，所以考生們一定要學(xué)會(huì)從長(zhǎng)難句中截取你所需要的能回答問(wèn)題的部分。簡(jiǎn)單點(diǎn)說(shuō)就是比如題干中問(wèn)你why….;那么，此時(shí)考生們?cè)诜治鲈亩ㄎ痪鋾r(shí)應(yīng)該重點(diǎn)看because這種能夠解釋的部分。
2). 考生們?cè)诒容^定位句與選項(xiàng)時(shí)切忌不能隨意推理，只需要把握文本的字面意思即可。
例1：
Paragraph 3: To what extent 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 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 law 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 occupy exactly the same niche. (TPO 29 Competition)
Paragraph 3 supports the idea that Gause’s 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 determines 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
解題步驟：
1). 讀題干，找出定位詞Gause’s experiments, 然后把握題目問(wèn)的內(nèi)容是有關(guān)于G的實(shí)驗(yàn)的importance。
2). 通過(guò)定位詞回到原文進(jìn)行定位，位于第三句話(huà)。但是第三句只提到了定位詞之一，接下來(lái)的第四句中提到了由此形成了一個(gè)law, 可以對(duì)應(yīng)題干中想問(wèn)的importance。
3). 第3句和第4句兩句定位句的大意為“當(dāng)只有一種食物來(lái)源被提供時(shí)，兩種物種中的一種會(huì)消亡。參照這些實(shí)驗(yàn)和觀察就形成了競(jìng)爭(zhēng)互斥規(guī)律----沒(méi)有哪兩種物種可以占據(jù)同樣的生態(tài)圈”，接下來(lái)瀏覽四個(gè)選項(xiàng)，發(fā)現(xiàn)C選項(xiàng)大意吻合----確定了競(jìng)爭(zhēng)將會(huì)移除其他所有的物種在任何一個(gè)生態(tài)圈里面。
例2：
As railroad linesfanned out from Chicago, 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 awesome 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 Deere 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 withdemand, 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.prairie 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.
解題步驟：
1).讀題干，找出定位詞settlers& open prairie land, 并且抓住題干問(wèn)的重點(diǎn)是because
2).根據(jù)定位詞定位到第一句和第三句這樣的語(yǔ)義群，這樣的語(yǔ)義群可以給我們提供一個(gè)大范圍定位，然后接下來(lái)考生們?cè)诘谒木淅锟吹搅薭ecause,所以第四句就是我們需要的精確定位點(diǎn)。
3).定位句的語(yǔ)義大約為“因?yàn)闁|部的耕種工具無(wú)法穿透這里的根部纏結(jié)在一起的草，因此，早期的定居者們將農(nóng)場(chǎng)建立在了遠(yuǎn)離草原的邊界地區(qū)?！苯酉聛?lái)瀏覽四個(gè)選項(xiàng)，只有A選項(xiàng)提到了因?yàn)楦鞴ぞ叩脑?，所以選擇A選項(xiàng)。
3、總結(jié)
1).此種題型必須要先閱讀題干，摸清題干所問(wèn)的具體內(nèi)容，然后再讀文章進(jìn)行定位
2).此種題型既可以只考察某一個(gè)特定的定位句理解;同時(shí)也可以考察2-3個(gè)定位句范圍的意群理解。但無(wú)論怎樣，考生絕對(duì)不是漫無(wú)目的地搜索，而是根據(jù)題干有目的性地尋找答案。
