 　　托福阅览中的揣度题一直是考生心思的暗影和惊骇，尤其是“揣度”两个字，瞬间会让咱们联想到柯南, 福尔摩斯之类带有悬疑颜色的东西。据对所带的学生进行的调查，说到哪种阅览题型最难做，将近50%的学生把票投给了揣度题。

　　毋庸置疑，揣度题必定有必定的难度地点，这点咱们从托福考试官方攻略(og)的改变上就可发现一些端倪。第三版og上，揣度题的考察数量为0-2题，第四版og现已增加到1-3题，ets的用(yin)意(mou)地点可见一斑。

　　那么，咱们改怎么应对揣度题呢?揣度题真的像咱们幻想的这么难么?

　　今日辛达代报和咱们一起来从考察方式上来解刨一下揣度题。

　　题干特征：揣度题的题干经常会呈现infer,suggest,imply, indicate这类单词

　　考察方式首要分为两大类：比照揣度和细节揣度，而后者呈现的几率更大。

　　考察方式一：比照揣度

　　A时刻比照：一般有两个构成比照的时刻点，它们所具有的特征一般相反。如：原文会呈现before1990的信息，而标题会问after 1990的信息?

　　解决方案：搜集问题对应的时刻点的信息，然后取反。

　　注意原文中呈现的表明时刻节点的词 before, after, not…until…

　　例题

　　The story of the westward movement of population in the United States is, in the main,the story of the expansion of American agriculture-of the development of new areas for theraising of livestock and the cultivation of wheat, corn, tobacco, and cotton. After 1815improved transportation enabled more and more western farmers to escape a self-sufficientway of life and enter a national market economy during periods when commodity prices werehigh, the rate of westward migration increased spectacularly. “Old America seemed to bebreaking up and moving westward,” observed an English visitor in 1817, during the first greatwave of migration. Emigration to the west reached a peak in the 1830’s, whereas in 1810 onlya seventy of the American people lived west of the Appalachian mountains, by 1840 more thana third lived there.

　　What can be inferred from paragraph 1 about western farmers prior to 1815?

　　○They had limited their crop production to wheat, corn, tobacco, and cotton.

　　○They were able to sell their produce at high prices.

　　○They had not been successful in raising cattle.

　　○They did not operate in a national market economy.

　　答案D

　　对应要害句：After 1815 improved transportation enabled more and more western farmersto escape a self-sufficient way of life and enter a national market economy during periodswhen commodity prices were high, the rate of westward migration increased spectacularly.

　　B直接比照：两个或多个事物的特征——如原文会呈现A的特色，然后会有B和A相比较的信息，然后标题问B的特色?

　　解决方案：搜集题干所问的揣度目标(about后边的信息一般为揣度目标)的悉数信息(一般为上述的B)，然后在原文所描绘的与之相关的信息(一般为上述的A)的基础之上取反。

　　注意原文中呈现的表明比照的关系词：by contrast, unlike, while, whereas,on the contrary, incomparison to, distinct from, different from等词。

　　例题

　　Paragraph 1: It should be obvious that cetaceans-whales, porpoises, and dolphins-aremammals. They breathe through lungs, not through gills, and give birth to live young. Theirstreamlined bodies, the absence of hind legs, and the presence of a fluke and blowholecannot disguise their affinities with land-dwelling mammals. However, unlike the cases of seaotters and pinnipeds (seals, sea lions, and walruses, whose limbs are functional both on landand at sea), it is not easy to envision what the first whales looked like. Extinct but, alreadyfully marine cetaceans are known from the fossil record. How was the gap between a walkingmammal and a swimming whale bridged? Missing until recently were fossils clearlyintermediate, or transitional, between land mammals and cetaceans.

　　Which of the following can be inferred from paragraph 1 about early sea otters?

　　○It is not difficult to imagine what they looked like

　　○There were great numbers of them.

　　○They lived in the sea only.

　　○They did not leave many fossil remains.

　　答案A

　　对应要害句：However, unlike the cases of sea otters and pinnipeds (seals, sea lions, andwalruses, whose limbs are functional both on land and at sea), it is not easy to envision whatthe first whales looked like.

　　考察方式二：细节揣度

　　考察细节判别，事物的特色，特点等。

　　解决方案：搜集题干所发问的揣度目标(about后边的信息一般为揣度目标)的一切信息。假如揣度目标所触及的信息比较多，难以抓到要点，则逐一选项进行定位挑选。

　　例题

　　Paragraph 1: Groundwater is the word used to describe water that saturates the ground,filling all the available spaces. By far the most abundant type of groundwater is meteoricwater; this is the groundwater that circulates as part of the water cycle. Ordinary meteoricwater is water that has soaked into the ground from the surface, from precipitation (rain andsnow) and from lakes and streams. There it remains, sometimes for long periods, beforeemerging at the surface again. At first thought it seems incredible that there can be enoughspace in the “solid” ground underfoot to hold all this water.

　　Which of the following can be inferred from paragraph 1 about the ground that we walkon?

　　○It cannot hold rainwater for long periods of time.

　　○It prevents most groundwater from circulating.

　　○It has the capacity to store large amounts of water.

　　○It absorbs most of the water it contains from rivers.

　　答案C

　　AThere it remains, sometimes for long periods, before emerging at the surface again.

　　BBy far the most abundant type of groundwater is meteoric water; this is thegroundwater that circulates as part of the water cycle.

　　C At first thought it seems incredible that there can be enough space in the “solid” groundunderfoot to hold all this water.

　　DOrdinary meteoric water is water that has soaked into the ground from the surface, fromprecipitation (rain and snow) and from lakes and streams.

　　综上所述，揣度题并没有咱们幻想的那么不流畅。它仍然是重视细节层面的标题，首要考察考生搜集和标题相关的信息和梳理这些信息的才能。咱们需求做到：

　　1把题干发问的揣度目标的信息搜集彻底，并了解到位。

　　2记居处看即所得，不要过火揣度，不要脑补。

　　3任何文章中呈现的信息都有可能考察揣度，所以不要忽略任何一个细节。
