托福閱讀如何才能更準(zhǔn)確的定位答案

　　發(fā)現(xiàn)不少這樣的同學(xué)，自認(rèn)閱讀不錯(cuò)，實(shí)際考出來(lái)的分?jǐn)?shù)只有22分左右，甚至?xí)汀TS對(duì)閱讀高水平(High level)的評(píng)定標(biāo)準(zhǔn)是22—30分。而事實(shí)上，閱讀如果達(dá)不到25分以上，總分想要過(guò)百會(huì)比較困難，因?yàn)檫@相當(dāng)于把掙分的壓力轉(zhuǎn)移到了大部分人比較弱的聽(tīng)力、口語(yǔ)、寫(xiě)作上面。由此可見(jiàn)，閱讀取得高分對(duì)于獲得百分以上的托福成績(jī)是一種保證!

　　“絆馬索”：細(xì)節(jié)題考查精確定位。

　　托福閱讀中的細(xì)節(jié)題其實(shí)不難，但前提是定位的點(diǎn)要對(duì)，比如下面這個(gè)例題：

　　Two species of deer have been prevalent in the Puget Sound area of Washington State in the Pacific Northwest of the United States. The black-tailed deer， a lowland， west-side cousin of the mule deer of eastern Washington， is now the most common. The other species， the Columbian white-tailed deer， in earlier times was common in the open prairie country， it is now restricted to the low， marshy islands and flood plains along the lower Columbia River.

　　According to paragraph 1， which of the following is true of the white-tailed deer of Puget Sound-

　　A. It is native to lowlands and marshes.

　　B. It is more closely related to the mule deer of eastern Washington than to other types of deer.

　　C. It has replaced the black-tailed deer in the open prairie.

　　D. It no longer lives in a particular type of habitat that it once occupied.

　　這是一個(gè)典型的細(xì)節(jié)題，在該題題干中，有的考生會(huì)選擇Puget Sound作為關(guān)鍵詞回原文定位，因?yàn)樗菍Ｓ忻~，在文中會(huì)比較顯眼。但是如果一旦選擇了這個(gè)地名，勢(shì)必會(huì)定位在該段的第一句話，托福細(xì)節(jié)題往往是定位在哪句就在哪句找答案，這樣的話考生是選不出正確答案的，因?yàn)槎ㄎ徊痪_。其實(shí)正確的關(guān)鍵詞應(yīng)該是white-tailed deer，這個(gè)用連字符連接的詞在文章中也是比較醒目的，按該詞定位應(yīng)是該段最后一句話。所以根據(jù)它的意思應(yīng)該選D項(xiàng)。其中A項(xiàng)與原句意思不符，B和C都與定位句信息無(wú)關(guān)。我們?cè)賮?lái)看另外一個(gè)否定事實(shí)細(xì)節(jié)題的例子：

　　Plant communities assemble themselves flexibly， and their structure depends on the particular history of the area. Ecologists use the term “succession” to refer to the changes that happen in plant communities and ecosystems over time. The first community in a succession is called a pioneer community， while the long-lived community at the end of succession is called a climax community. Pioneer and successional plant communities are said to change over periods from 1 to 500 years. These changes—in plant numbers and the mix of species—are cumulative. Climax communities themselves change but over periods of time greater than about 500 years.

　　According to paragraph 1， which of the following is NOT true of climax communities-

　　A. They occur at the end of a succession.

　　B. They last longer than any other type of community.

　　C. The numbers of plants in them and the mix of species do not change

　　D. They remain stable for at least 500 years at a time.

　　這個(gè)題大家都會(huì)選擇用climax communities去定位，但在定位過(guò)程中會(huì)出現(xiàn)很多問(wèn)題。首先考生要學(xué)會(huì)跳躍式定位，即根據(jù)文章中特殊的標(biāo)點(diǎn)符號(hào)以及最醒目的詞來(lái)搜索我們真正需要的關(guān)鍵詞。文中的particular是加了陰影的，succession是在引號(hào)里面的，都非常醒目，通過(guò)看這兩個(gè)詞我們會(huì)發(fā)現(xiàn)它們附近沒(méi)有我們需要的東西;再比較突出的就是數(shù)字及破折號(hào)，在500的上方有a climax community，但它是單數(shù)，與題干關(guān)鍵詞不完全匹配，細(xì)節(jié)題講究的是精確定位，所以我們應(yīng)該選擇500斜下方的Climax communities，即該段的最后一句話。否定事實(shí)細(xì)節(jié)題的出題思路有兩種：一是無(wú)中生有，即根據(jù)定位點(diǎn)的內(nèi)容，四個(gè)選項(xiàng)只有一個(gè)沒(méi)有提到，這種思路多適用于選項(xiàng)比較簡(jiǎn)短的題目;二是張冠李戴，即根據(jù)定位點(diǎn)的內(nèi)容表述，只有一個(gè)選項(xiàng)與之矛盾，這種思路多適應(yīng)于選項(xiàng)比較長(zhǎng)的題目。就這個(gè)例題而言，根據(jù)定位的最后一句話，從表述上來(lái)說(shuō)跟它相關(guān)的只有C和D兩個(gè)選項(xiàng)，D項(xiàng)的意思與原句相符，而C項(xiàng)與原句矛盾，所以正確答案是C。綜上所述，做新托福閱讀的細(xì)節(jié)題，最重要的一點(diǎn)就是要盡量地去精確定位。
