托福閱讀定位時要避開這些“陷阱”!

相信上過托福課程或者參加過托福考試的同學都知道,托福閱讀考試時間有限,自2019年8月1日改革以來,3篇文章的答題時間是54分鐘,也就是平均18分鐘要完成一篇閱讀文章里的10道題。

相信上過托福課程或者參加過托福考試的同學都知道,托福閱讀考試時間有限,自2019年8月1日改革以來,3篇文章的答題時間是54分鐘,也就是平均18分鐘要完成一篇閱讀文章里的10道題。這對于大多數學生都是一個不小的挑戰。那么,我們如何在有限的時間內做對盡可能多的題目就成了取得高分的關鍵。

 面對一篇800詞左右的文章,我們如何快速地找到每道題的出題句呢?答案就是“定位”。定位詞我們一般都會選擇名詞,首字母大寫的人名,地名,數字,時間和標點,因為這些詞匯都比較“顯眼”,是能夠讓大家在掃讀段落時迅速鎖定的詞匯,那么這樣的定位詞選擇一定靠譜嗎?答案當然是否定的

接下來我們一起來看看閱讀定位時要避開的“陷阱”有哪些。

陷阱1:利用時間或者地名定位到段落某一句,可能整個段落描述的信息都是這個時間或者地點發生的,導致定位無效。

舉個栗子——

The vast grasslands of the High Plains in the central United States were settled by farmers and ranchers in the 1880s. This region has a semiarid climate, and for 50 years after its settlement, it supported a low-intensity agricultural economy of cattle ranching and wheat farming. In the early twentieth century, however, it was discovered that much of the High Plains was underlain by a huge aquifer (a rock layer containing large quantities of groundwater). This aquifer was named the Ogallala aquifer after the Ogallala Sioux Indians, who once inhabited the region. (TPO-3-Depletion of the Ogallala Aquifer-第1題)

According to paragraph 1, which of the following statements about the High Plains is true?

A. Until farmers and ranchers settled there in the 1880s, the High Plains had never been inhabited.

B. The climate of the High Plains is characterized by higher-than-average temperatures.

C. The large aquifer that lies underneath the High Plains was discovered by the Ogallala Sioux Indians.

D. Before the early 1900s there was only a small amount of farming and ranching in the High Plains.

 根據題干信息,首字母大寫的短語High Plains能幫助我們定位到段落第一句(The vast grasslands of the High Plains in the central United States were settled by farmers and ranchers in the 1880s.) 和第三句 (In the early twentieth century, however, it was discovered that much of the High Plains was underlain by a huge aquifer (a rock layer containing large quantities of groundwater).) 

讀完這兩句話后我們發現并無意思相對應的選項。其實,整段話描述的信息都是發生在High Plains地區的,所以如果看看原文句子的話,必須通讀全段,或者利用選項定位法。通讀全段后我們發現正確選項是D,對應的是段落的第二句話和第三句話。

建議:利用地名或時間定位時要小心,當定位句沒有對應的選項時要馬上看其余的句子。

陷阱2:找錯核心定位詞,導致定位出錯

 

舉個栗子——

In the face of the upcoming water supply crisis, a number of grandiose schemes have been developed to transport vast quantities of water by canal or pipeline from the Mississippi, the Missouri, or the Arkansas rivers. Unfortunately, the cost of water obtained through any of these schemes would increase pumping costs at least tenfold, making the cost of irrigated agricultural products from the region uncompetitive on the national and international markets.Somewhat more promising have been recent experiments for releasing capillary water (water in the soil) above the water table by injecting compressed air into the ground.Even if this process proves successful, however, it would almost triple water costs. Genetic engineering also may provide a partial solution, as new strains of drought-resistant crops continue to be developed. Whatever the final answer to the water crisis may be, it is evident that within the High Plains, irrigation water will never again be the abundant, inexpensive resource it was during the agricultural boom years of the mid-twentieth century.(TPO-3-Depletion of the Ogallala Aquifer-第12題)

According to paragraph 6, what is the main disadvantage of the proposed plans to transport river water to the High Plains?

A. The rivers cannot supply sufficient water for the farmer’s needs.

B. Increased irrigation costs would make the products too expensive.

C. The costs of using capillary water for irrigation will increase.

D. Farmers will be forced to switch to genetically engineered crops.

同上題一樣,很多同學看到這道題時會馬上選擇High Plains作為定位詞,定位到段落最后一句(Whatever the final answer to the water crisis may be, it is evident that within the High Plains, irrigation water will never again be the abundant, inexpensive resource it was during the agricultural boom years of the mid-twentieth century.),同樣的,讀完句子后發現沒有對應的選項,那么問題出在哪兒呢? 

提醒各位同學,選擇定位詞的時候一定要選的是核心定位詞,而不是看到大寫字母就用來定位。那么這一題的核心定位詞就是:disadvantage, plans, transport river water。那么我們就可以定位到段落的前兩句(In the face of the upcoming water supply crisis, a number of grandiose schemes have been developed to transport vast quantities of water by canal or pipeline from the Mississippi, the Missouri, or the Arkansas rivers. Unfortunately, the cost of water obtained through any of these schemes would increase pumping costs at least tenfold, making the cost of irrigated agricultural products from the region uncompetitive on the national and international markets.)。 很明顯,這兩句話對應的是B選項。 

建議:審題時一定要仔細,判斷出核心定位詞才能做出高效且正確的定位
