例：

　　Very high waves are destructive when they strike the land. Fortuately, this seldom happens. One reason is that out at sea, waves moving in one direction almost always run into waves moving in a different direction. The two sets of waves tend to cancel each other out. Another reason is that water is shallower near the shore. As a wave gets closer to land, the shallow bottom helps reduce its strength.

　　But the power of waves striking the shore can still be very great. During a winter gale, waves sometimes strike the shore with the force of 6,000 pounds for each square foot. That means a wave, 25 feet high and 500 feet along its face, may strike the shore with a force of 75 million pounds.

　　Yet the waves, no matter how big or how violent, affect only the surface of the sea. During most raging storms, the water a hundred fathoms（600 feet） beneath the surface is just as calm as on a day without a breath of wind.

　　Question: From your reading of the paragraph, which of the following is true? A. At a depth of 1,200 feet the effects ofa violent surface storm are frightful.

　　B. A submarine commander navigating his vessel at a depth of 700 feet will not be affected by a raging surface storm.

　　C. A typhoon 500 miles out at sea can stir up the ocean bed.

　　D. If high waves can strike the shore with a horizontal force of 75 million pounds, the vertical force of such waves can have an even greater effect upon the ocean floor.

　　说明：本题答案为B项。此项为判断题。在本文报后一段，作者表述的意思为：不管海浪多高，多凶猛，它只影响到海面以下有限的深度。即使在最大的风暴中，600英尺以下尝试的水域也会像没有一丝风的白天那样风平浪静。选顼A意为“狂风巨浪会对1200英尺以下的水域造成可怕的影响”；B项意为“一名在水深700英尺以下驾驶潜艇行的指挥员有会受海面上的狂风巨浪的影响”；C项意为“风速每小时500英里的台风能海底的东西掀上来”；D项意为“如果巨浪袭击海岸的力量水平方向为75000000磅，那么它的垂直方向作用在海底的力量比水平方向作用力还要大”。根据最后一段内容，只有B项正确，因为潜艇是在700英尺以下水域航行。A项，C项与B项矛盾，可以排除，D项在短文中没有涉及。正是基于对这部分进行研读，考生才能够得出正确答案。

　　5． 整体阅读

　　一篇文章是一个整体。文章作者通过整篇文章的构思、布局、对事物的论证、说明、叙述和描写等方法向读者传授知识和信息。知识和信息是存在于整篇文章之中，而不是存在于孤立的词句之内。在阅读句、段、篇时都应从整体原则出发。这样才能既理解字面含义，又能洞察深层含义；既能看到上下文呼应的语言结构，又能体会到字里行间的潜在含义；既能了解文章的各局部的含义，又能抓住文章的中心思想，从而对整篇文章达到较高层次的理解。

　　整体阅读有两个层次：

　　（1） 篇章的阅读。在阅读一篇文章时，应从五个方面驾驭整篇文章，遵循如下的模式：文章的标题；作者；基本内容；事实；文章的特点、争议和批评意见。这样可以避免盲目性和疏忽遗漏。阅读时，可把主要精力放在有用信息上，大大减少处理无用作息的时间，并使信息条理化，以便理解和吸收。

　　（2） 句、段的阅读。句子是一个整体，段也是一个整体。阅读句子时，如果不太长，要一口气读完。这样不仅读速快，而且有助于理解。当然，英语句子一般比较长，不能一口气读完。这时应以较大的意群为单位进行阅读。所谓意群是指句子中可以分开来看的各个部分，每个部分都有其相对独立的意义。
