【導(dǎo)讀】IBT閱讀中的表格題是新題型，同時在IBT聽力部分也出現(xiàn)了。既包括了對全文重點內(nèi)容的發(fā)問又包括了對全文主題和結(jié)論發(fā)問。在IBT閱讀的3篇文章中有兩個此類問題，且通常是文章最后一。道題目，為2分。對照關(guān)系這三方面的因素決定的。一種是針對全文內(nèi)容出題，答案由全文的主題，細節(jié)和重點支持段落的概述三部分組成。我們來看一個例子，

Complete the summary by selecting the THREE answer choices that express the most important ideas in the passage. Some sentences do not belong 8 in the summary because they express ideas that are not presented in the passage or are minor ideas in the passage. This question is worth 2 points. An expedition to the Mediterranean answered some longstanding questions about the ocean’s history. ○ ○ ○ Answer choices 1. The Glomar Challenger expedition investigated changes in invertebrate fauna and some unusual geologic features. 2. Researchers collected fossils to determine which new species migrated from the Atlantic with older species. 3. Scientists aboard the Glomar Challenger were the first to discover the existence of domelike masses underneath the seafloor. 4. Samples recovered from the expedition revealed important differences in chemical position and fossil distribution among the sediment layers. 5. Evidence collected by the Glomar Challenger supports geologists39。 beliefs that the Mediterranean had evaporated and bee a desert, before it refilled with water. 6. Mediterranean salt domes formed after crustal movements opened the straits between the Mediterranean and the Atlantic, and the Mediterranean refilled with water. Ancient Rome and Greece There is a quality of cohesiveness about the Roman world that applied neither to Greece nor perhaps to any other civilization, ancient or modern. Like the stone of Roman wall, which were held together both by the regularity of the design and by that peculiarly powerful Roman cement, so the various parts of the Roman realm were bonded into a massive, monolithic entity by physical, anizational, and psychological controls. The physical bonds included the work of military ?garrisons 要塞 , which were stationed in every province, and the work of stonebuilt roads that linked the provinces with Rome. The anizational bonds were based on the mon principles of law and administration and on the universal army of officials who enforced mon standards of conduct. The psychological controls were built on fear and punishment—on the absolute certainty that anyone or anything that threatened the authority of Rome would be utterly destroyed. 古代羅馬和希臘 羅馬具有一種希臘和其他任何不論是古代還是現(xiàn)在文明都不具備的凝聚力。羅馬墻上的石塊 是靠設(shè)計的規(guī)整和特別有力的粘合劑而被固定在一起，與此相同羅馬帝國的各個部分也因物理的、組織的和精神的束縛而組成了一個堅若磐石的整體。物理的束縛包括駐扎在每個省的戍衛(wèi)軍組成的網(wǎng)絡(luò)和聯(lián)通每個省與羅馬的、用石頭鋪成的道路網(wǎng)絡(luò)。組織上的羈絆則基于法律和行政的一般原則，以及遍布各地、統(tǒng)一行動的軍政府。精神上的控制則建立在恐懼和懲罰上 ——毫無疑問的是任何人，或任何事，只要威脅到羅馬的權(quán)威，都終將被摧毀。 The source of Roman obsession with unity and cohesion may well have lain in the pattern of Rome‘s early development. Whereas Greece had grown from scores of scattered cities, Rome grew from one single anism. While the Greek world had expanded along the Mediterranean seas lanes, the Roman world was assembled by territorial conquest. Of course, the contrast is not quite so stark: in Alexander the Great the Greeks had found the greatest territorial conqueror of all time。 and the Romans, once they moved outside Italy, did not fail to learn the lessons of sea power. Yet the essential difference is undeniable. The Key to the Greek world lay in its highpowered ships。 the key to Roman power lay in its marching legions. The Greeks were wedded to the sea。 the Romans, to the land. The Greek was a sailor at heart。 the Roman, a landsman. 羅馬人對統(tǒng)一和團結(jié)的執(zhí)著可能源自于羅馬早期的發(fā)展模式。希臘是從二十幾個分散的城邦發(fā)展而來，然而羅馬則是從單個組織發(fā)展而來。希臘沿著地中海擴張，然而羅馬帝國則通過領(lǐng)土的占領(lǐng)而壯大。當然，他們的對比也不是那么的絕對：在亞歷山大大帝時期，希臘找到了他們整個歷史中最大的領(lǐng)地征服者；羅馬人雖曾一度遷 9 移到意大利之外，但他們卻沒有荒廢海洋的力量。然而，他們之間本質(zhì)的區(qū)別是不容否認的。希臘世界的關(guān)鍵是強大的船隊，而羅馬帝國的關(guān)鍵則是他們行進的部隊。希臘人死守著海洋，羅馬人則死守著土地。希臘人是天生的水手，羅馬人則是陸上強兵 。 Certainly, in trying to explain the Roman phenomenon, one would have to place great emphasis on this almost instinct for the territorial imperative. Roman priorities lay in the anization, exploitation, and defense of their territory. In all probability it was the fertile plain of Latium, where the Latins who founded Rome originated, that created the habits and skills of landed settlement, landed property, landed economy, landed administration, and a landbased society. From this arose the Roman genius for military anization and orderly government. In turn, a deep attachment to the land, and to the stability which rural life engenders 產(chǎn)生 , fostered the Roman virtues: gravitas, a sense of responsibility, peitas, a sense of devotion to family and country, and iustitia, a sense of the natural order. 毫無疑問的是，為了解釋羅馬現(xiàn)象，人們應(yīng)該極大的強調(diào)他們的幾乎是本能的領(lǐng)土觀念。羅馬人的天性就在于對領(lǐng)土的組織、擴張和防御。完全也可能是 Latium平原 ——拉丁人最初建立羅馬的地方，早就 了羅馬人陸地定居、陸地財產(chǎn)、陸地經(jīng)濟、陸地行政以及以陸地基礎(chǔ)社會的性格和技巧。在此基礎(chǔ)上也產(chǎn)生了羅馬人的軍事組織和政府管理的才能。反過來，對土地以及穩(wěn)定鄉(xiāng)村生活的深深的依戀孕育了羅馬人的品格： gravitas，一種責任
