智 课 网 托 福 备 考 资 料 托福阅读词汇题的较难情形-智课教育旗下智课教育 本文是智课教育小编为考生带来的托福阅读词汇题的较难情形。不 管是单独从单词意思的角度还是单独从上下文猜词的角度，托福阅读词 汇题的解题都可能出现问题。 托福阅读词汇题是托福阅读中出现次数比较多的题型，在托福阅读 词汇题目解题时，考生能够提高答对率的最保险方式是根据已知的题干 词汇含义结合上下文猜测词义。这里提到了两点，首先，大家要了解这 个词;其次，大家通过语境来确认词义。 智课教育小编不得不提的是，大部分考生是不会这样答题的，因为 大家的做法往往有两种情况：第一种是，考生了解这个词，所以直接选 出选项，当然依靠的是这个词本来的含义;第二种是，考生不认识这个词 ，所以只能依靠文章的上下文理解去猜测词义。这两种方式的缺陷是很 明确的，第一种方法中，考生没有顾忌上下文，所以在词汇有多重含义 的时候有可能答错题目;第二种，考生本身对词汇没有什么认识，仅根据 自己的文章理解猜测，在理解出现偏差的时候答题也会出现偏差。 以上是对托福阅读词汇题答题方法的分析。接下来，小编为大家带 来一些托福阅读词汇题的较难情形，根据这些题目希望考生可以理解以 上的内容。 例1：词汇不认识，理解容易出错的情形 Paragraph 2: The source had long been known but not exploited. Early in the eighteenth century, a pump had come into use in which expanding steam raised a piston in a cylinder, and atmospheric pressure brought it down again when the steam condensed inside the cylinder to form a vacuum. This “atmospheric engine,” invented by Thomas Savery and vastly improved by his partner, Thomas Newcomen, embodied revolutionary principles, but it was so slow and wasteful of fuel that it could not be employed outside the coal mines for which it had been designed. In the 1760s, James Watt perfected a separate condenser for the steam, so that the cylinder did not have to be cooled at every stroke; then he devised a way to make the piston turn a wheel and thus convert reciprocating (back and forth) motion into rotary motion. He thereby transformed an inefficient pump of limited use into a steam engine of a thousand uses. The final step came when steam was introduced into the cylinder to drive the piston backward as well as forward, thereby increasing the speed of the engine and cutting its fuel consumption. 3. The word “exploited” in the passage is closest in meaning to ○utilized ○recognized ○examined ○fully understood 解析 ：答案是A。所在句 ：The source had long been known but not exploited. “这种动力来源长期为人们所知但却没被…“通过转 折关系可知B、D错误 ，之后讲的都是蒸汽机怎样改良 ，怎样利用。所
