託福閱讀邏輯考點，你知多少？
首先，在閱讀中會出現的邏輯除了常見的因果、並列、轉折和比較以外，考生們還需要清楚的是舉例、指代、否定和順序也是閱讀裏面常見的邏輯。每一個邏輯對於解題和把握段落結構都是非常重要的。
以我們常見的比較邏輯爲例。比較邏輯出現的時候需要關注四個要素：比較對象、比較方面、比較大小和比較的限制範圍。舉箇中文例子：在冬天，南方比北方更冷。在這個句子中我們看到的比較對象即南方vs北方，比較方面即氣溫（冷），比較大小即南方>北方（南方更冷），比較的限制範圍即在冬天。出現比較邏輯的時候題目的考點便落在這四要素上了，只要選項中對象錯或者方面錯或者大小反了或者限制範圍被更改，便可以判斷該選項爲錯誤項。在解題的時候完全可以根據相應的考點來區分正誤。
比如：
It is also possible that the costs of job changing by employees vary internationally. Data suggest that workers in the United States may well be more likely to change employers than workers elsewhere may be. Indeed, data confirm that, on average, American workers have been with their current employers fewer years than workers in most other developed countries, particularly workers in Europe and Japan, have been with theirs. It is not known why Americans are more mobile than most others are, but one possibility relates to the lower levels of company training received by American workers. Another possibility, however, is that the costs of mobility are lower in the United States (despite the fact that Japan and Europe are more densely populated and hence more urban). What would create these lower costs?
5. According to paragraph 3, what is one possible explanation for why American workers change jobs more frequently than workers elsewhere do?
A.The relatively small percentage of American workers who live in urban areas
B.The tendency of American employers to provide less training for workers
C.The recent decrease in mobility costs in the United States
D.The lower average population density in the United States
在這道細節題中，我們可以根據題幹關鍵詞 why American、more frequently than從上往下讀到but one possibility relates to the lower levels of company training received by American workers. Another possibility, however, is that the costs of mobility are lower in the United States這部分內容判斷爲該題答案，答案句可看到出現了兩對比較邏輯，AD均未涉及原答案句中的比較四要素。原句中爲同一時間點下，比較對象爲USA與其他國家，比較方面分別爲training和costs，比較大小都是USA< 其他國家，那麼在選項中的C選項是儘管出現了costs這個比較方面，但是可以發現這個選項中的比較對象並非USA與其他國家，而是同一對象在不同時間點的比較，由此可以判斷比較對象發生了變化，從而辨認出該選項是錯誤項；B選項中則保留了less training這個比較，且比較大小與原句一致，是USA與的國家做對比而非同一對象USA不同時間前後的對比，因此可以判斷B爲正確選項。
所以，瞭解相應的邏輯考點可以很快幫助考生識別出選項正誤，從而避開錯誤項選出正確項。
