如何提高雅思阅读效率 雅思备考

　　考生们在做阅读时经常会有某句话翻译不通从而造成理解障碍的问题。实际上阅读中的很多词汇用法并非是我们比较熟悉或者想当然的那个含义。比如“mine”这个单词，在学术文章中经常表示“矿物”而并非‘我的’。
　　因此为了提高大家的阅读理解质量，考生们要学会掌握某些常见单词的其他“学术”含义。
　　1. in turn
　　大多数同学会理解为 “反过来”，认为前后语义是对立的，但实际上阅读中也可能表示顺接关系，翻译为“接着会…(发生)…”
　　The conventional theory is that people yawn when bored or sleepy because yawning raises blood oxygen levels, which in turn raises alertness.
　　2. account for
　　大家背四级单词时更多的理解为 “(比例上)占…”的含义，实际上account for还有“解释，说明……”这个意思。
　　Heavy rain accounts for most of the water that enters into lakes.
　　Scientists will not be able to account for climate changeover the past century until they learn more about the urban heat island.
　　3. precipitation
　　这是个话题词汇，大多数文章中翻译为 “沉淀”，不过也有“降水”的意思。
　　Ordinary meteoric water is water that has soaked into the ground from the surface, from precipitation (rain and snow) and from lakes and streams.
　　4. game
　　不是游戏哦，在学术文章中经常用来表达“野生猎物”这个意思。下次课别再困惑了。
　　They had experienced great difficulty finding game west of the Rockies and not until the second of December did they kill their first elk.
　　5. solution
　　除了“解决方案”，还要知道另一个常见含义“溶液”。这个词在小作文流程图写作中也是一个得分高级词汇。
　　Mineral deficiencies in many plants can be cured by misting their roots with a nutrient solution or by transferring the plants to a soilless nutrientsolution.
　　6. current
　　又一个学科背景词汇。常见的是形容词表“当下的”，实际还有“洋流、电流、气流”等含义。
　　The same thing happens to this day, though on a smaller scale, wherever a sediment-laden river or stream emerges from a mountain valley onto relatively flat land, dropping its load as the current slows: the water usuallyspreads out fanwise,depositing the sediment in the form of a smooth, fan-shaped slope.
　　7. browse
　　家熟知的是“浏览”的含义，而实际上托福阅读中更常表达得是“觅食”这个意思。
　　Where the forest inhibits the growth of grass and other meadow plants, the black-tailed deer browses on huckleberry, salal, dogwood, and almost any other shrub or herb. But this is fair-weather feeding.
　　8. impact
　　除了“影响”，还衍生出“冲击、撞击”的意思。这里提醒大家impact指代的影响也常常是负面含义的影响，大家在写作中要注意。
　　In view of these facts, scientists hypothesized that a single large asteroid, about 10 to 15 kilometers across, collided with Earth, and the resulting fallout created the boundary clay. Their calculations show that the impact kicked up a dust cloud that cut off sunlight for several months, inhibiting photosynthesis in plants; decreased surface temperatures on continents to below freezing…
　　9. complex
　　作为名词的时候可以表达“建筑群”的含义。
　　It had over 2,000 apartment complexes, a great market, a large number of industrial workshops, an administrative center, a number of massive religious edifices…
　　10. readily
　　别因为长得像“ready”就是准备好的意思，这个词其实是“容易地”意思。
　　The release of heat energy is retarded by the tallverticalcity walls that do not allow infrared radiation to escape as readily asdoes the relatively level surface of the surrounding countryside.
　　11.evident
　　又一个大家习惯想当然的词。都说成“证据”就不对了，还要知道“明显的”。
　　Wind velocity also increases with altitude and may cause serious stress for trees, as is made evident by the deformed shapes at high altitudes.
　　12. collectively
　　不能望文生义为“收集地”，还有“共同地”这个释义较为常见。
　　Eventually, six round forms of handwriting, composed of three pairs of big and little scripts known collectively as the Six Pens, became the standard repertory of every calligrapher.
　　13. evenly
　　别以为“even”加个“-ly”就是甚至的副词形式，别忘了 “even”本来就是个副词。这个词是“均匀地”。
　　Petroleum forms best when organic matter is evenly distributed over …
　　其他常被误解的单词
　　sweet water 淡水 (不是“糖水”)
　　confidence man (不是“信得过的人”)
　　criminal lawyer 刑事律师(不是“犯罪的律师”)
　　service station 加油站
　　rest room 厕所(不是“休息室”)
　　sporting house 妓院或赌场(不是“体育室”)
　　horse sense 常识(不是“感觉”)
　　capital idea 好主意(不是“资本思想”)
