2012新GRE閱讀題型之細節(jié)題全攻略(6)
     羅馬數(shù)字題
    羅馬數(shù)字題是GRE閱讀中出現(xiàn)比較多的一種題型,通常情況,考試的題型中定會有一道或兩道這類題型。雖然,出題的數(shù)目不是很多,但是也要特別注意。羅馬數(shù)字題主要考查考生對文章的理解以及一些邏輯推理能力。在對文章的時候要對一些例子、解釋等特別關(guān)注,要在文中做好標(biāo)記,以便迅速地找到答案。
    羅馬數(shù)字題題的基本結(jié)構(gòu):
    The author provides following which of the following examples in the passage?
    1.Ⅰ only
    2.Ⅱ only
    3.Ⅲ only
    4.Ⅰ & Ⅱ
    5.Ⅱ & Ⅲ
    當(dāng)遇到羅馬數(shù)字題時,首先回原文找列舉,沒有列舉再繼續(xù)看題做答。做大多數(shù)羅馬數(shù)字題有捷徑可走的,考生應(yīng)該在看完選項后先看備選答案。比如,幾個備選答案都有Ⅰ,則Ⅰ肯定是正確的,就不必再判斷了。
    下面舉一個具體的例子:
    The recent, apparently successful, prediction by mathematical models of an appearance of El Nino—the warm ocean current that periodically develops along the Pacific coast of South America—has excited researchers……
    It has long been known that during an El Nino, two conditions exist: (1) unusually warm water extends along the eastern Pacific, principally along the coasts of Ecuador and Peru, and (2) winds blow from the west into the warmer air rising over the warm water in the east.These winds tend to create a feedback mechanism by driving the warmer surface water into a “pile” that blocks the normal upwelling of deeper, cold water in the east and further warms the eastern water, thus strengthening the wind still more.The contribution of the model is to show that the winds of an El Nino, which raise sea level in the east, simultaneously send a signal to the west lowering sea level.According to the model, that signal is generated as a negative Rossby wave, a wave of depressed, or negative, sea level, that moves westward parallel to the equator at 25 to 85 kilometers per day.Taking months to traverse the Pacific, Rossby waves march to the western boundary of the Pacific basin, which is modeled as a smooth wall but in reality consists of quite irregular island chains, such as the Philippines and Indonesia.考試用書

    無論做什么題,我們在對完文章后,都要清楚一個基本的問題,就是文章的結(jié)構(gòu)和行文思路。這篇文章屬于結(jié)論解釋型文章,作者在第一段的第一句話就提出了結(jié)論,后面所以內(nèi)容都是對這個結(jié)論的解釋說明。所以,文章的首句是全文的中心句(topic sentence)。
    It can be inferred from the passage that which of the following would result fairly immediately from the cessation of the winds of an El Nino?
    I.Negative Rossby waves would cease to be generated in the eastern Pacific.
    II. The sea level in the eastern Pacific would fall.
    III. The surface water in the eastern Pacific would again be cooled by being mixed with deep water.
    (A) I only
    (B) II only
    (C) I and II only
    (D) I and III only
    (E) I, II, and III
