在雅思阅读考试中，篇幅比较长。很多考生因为篇幅太长，再加上自己的理解能力和阅读速度不够，有时候会答不完题，接下来小编为大家带来了雅思阅读核心词分析，大家可以积累一些词汇，帮助我们能理解文章。
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.

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.

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。

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 usually spreads 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
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.

9. complex
作为名词的时候可以表达“建筑群”的含义。

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”。

12. collectively

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”。
