如何用比較邏輯解決托福閱讀題學(xué)習(xí)一下

中國教育在線小編為大家收集整理了如何用比較邏輯解決托福閱讀題？學(xué)習(xí)一下！，那么接下來就跟著小編一起來看看，相信你通過以下的文章內(nèi)容就會有更深入的了解。

首先，注意原文/題目/選項中出現(xiàn)的比較邏輯詞：

表相同

1.same、similar、equal、alike、identical（可靠identical twins同卵雙胞胎來背誦這個單詞）

2.as...as、just as

3.前綴homo-

表不同

1.比較級-er...than、最高級the most/-est

2.rather than(而不是)

3.whereas、while、although/but、unlike、not asas

其次，定位好后將原句與選項進(jìn)行同義轉(zhuǎn)換

表相同的情況：

TPO 48 R2 Determining Dinosaur Diet

Animals such as house cats and dogs have large,stabbing canine teeth at the front of the mouth and smaller,equally sharp teeth farther back in their jaws.Many of these animals are also armed with sharp claws.The advantage of teeth and claws as predatory tools is obvious.Now consider animals like cows,horses,rabbits,and mice.These animals have flat teeth at the back of the jaw that are analogous to and have the same function as grindstones.Unlike the meat-slicing and stabbing teeth of carnivores,the teeth of these animals grind and shred plant material before digestion.

2.According to paragraph 2,which of the following is true of the teeth of carnivores?

A.Carnivoresteeth for grinding and shredding are located in the front of their jaws

B.Carnivore teeth are designed to break down food thoroughly before digestion

C.Carnivores have teeth at the back of their jaws that are as sharp as their front teeth

D.Carnivores have both sharp teeth for slicing meat and flat teeth for grinding meat

分析：原文說某些動物嘴里前面大的牙齒和后面小的牙齒一樣鋒利（equally sharp），同義替換C選項backas sharp asfront。

TPO 41 R3 Trade And Early State Formation

In the 1970s,a number of archaeologists gave trade a primary role in the rise of ancient states.British archaeologist Colin Renfrew attributed the dramatic flowering of the Minoan civilization on Crete and through the Aegean to intensified trading contacts and to the impact of olive and vine cultivation on local communities.As agricultural economies became more diversified and local food supplies could be purchased both locally and over longer distances,a far-reaching economic interdependence resulted.Eventually,this led to redistribution systems for luxuries and basic commodities,systems that were organized and controlled by Minoan rulers from their palaces.As time went on,the self-sufficiency of communities was replaced by mutual dependence.Interest in longshy;-distance trade brought about some cultural homogeneity from trade and gift exchange,and perhaps even led to piracy.Thus,intensified trade and interaction,and the flowering of specialist crafts,in a complex process of positive feedback,led to much more complex societies based on palaces,which were the economic hubs of a new Minoan civilization.

5.According to paragraph 2,Renfrew believed that one effect of long-distance trade in the Aegean was

A.a greater effort to control piracy

B.greater cultural similarity throughout the region

C.a decline in local olive production

D.a decline in the use of luxuries for gift exchanges

分析：用effect of long-distance trade定位到原句后，cultural homo-同義轉(zhuǎn)換成選項B里的cultural similarity（都表文化相同）。

表不同的情況：

TPO 44 R3 Seagrasses

Seagrass beds under the influence of strong currents tend to have many of the lighter particles,including seagrass debris,moved out,whereas beds in weak current areas accumulate lighter detrital material.

Question:Which of the sentences below best expresses the essential information in the highlighted sentence in the passage?Incorrect choices change the meaning in important ways or leave out essential information

A.Light particles and debris collect in some seagrass beds,but are washed out of those affected by strong currents.

B.Seagrass beds under the influence of strong currents tend to accumulate many of the lighter particles from other beds.

C.The strength of the currents determines how quickly accumulated seagrass debris is moved out of the beds.

D.Seagrass debris and other light particles are often moved from areas of strong currents to areas of weak currents.

分析：對于部分詞匯不夠完善的同學(xué)來說，這個原句有一定難度；但原句出現(xiàn)whereas，同學(xué)們要理解成拿strong currents和weak currents進(jìn)行比較。只有選項A用雖然。。。但是。。。來表達(dá)出比較的意思，所以即使在原句沒有完全讀懂的基礎(chǔ)上，也應(yīng)該選A。

長難句：Immediately adjacent to the timberline,the tundra consists of a fairly complete cover of low-lying shrubs,herbs,and grasses,while higher up the number and diversity of species decrease until there is much bare ground with occasional mosses and lichens and some prostrate cushion plants.

分析：這個句子難點在于和植物相關(guān)的專業(yè)詞匯非常多，逐字逐句翻譯非常困難而且浪費時間。此句出現(xiàn)while，而且后接在更高的地方（higher up），物種的數(shù)量和多樣性會下降，所以應(yīng)該根據(jù)對比邏輯合理猜測：在海拔低的地方，植物的多樣性和數(shù)量都會上升。特別是在題目沒有對此句進(jìn)行提問的情況下，靠邏輯讀句更能加快讀句速度。
