雅思对于一词多义，同义替换的考察是重中之重，相信这已经是大家的共识。但是一词多义究竟怎么用，怎么才能在日常联系中了解和掌握一词多义？这就要让环球君来告诉大家啦！
通过上下文理解这种情况在雅思阅读中时有发生。本来可能是一个很简单的词语，但是由于出现在了长难句中，导致其“摇身一变”就变成了你看不懂的样子。这个时候抓句子主干+联系上下文就是尤其重要的了。
为大家举几个例子，我们一起来看下：
例题：剑4 Test 1 Passage 1
In other words， they gave no indication of an appreciation of either the range of ways in which rainforests are important or the complex social， economic and political factors which drive the activities which are destroying the rainforests.
长难句！部分烤鸭看见就昏头了……但是我们现在抓出句子主干，找到
ways in which
factors which
activities which
这三个定语从句抓出时候，有么有感到豁然开朗？我们再来找到drive，发现句子主干应该是factors drive …… 如果将drive翻译成【驾驶】，那么就是【真相驾驶……】显然是不合理的，所drive在这里的意思是【导致】,相当于factors lead to……
适当缩句，就可以帮助自己更好的抓住重点。
例题：剑5 Test1 Passage 1
单选题 Q20 The teacher-subjects were told that they were testing whether
A a 450-volt shock was dangerous.
B punishment helps learning.
C the pupils were honest.
D they were suited to teaching.
文章原段落如下：
Specifically， Milgram told each volunteer 'teacher-subject' that the experiment was in the noble cause of education， and was designed to test whether or not punishing pupils for their mistakes would have a positive effect on the pupils' ability to learn.
我们发现这里的teacher-subject打了引号，也就是提醒烤鸭们，不认识不要紧，直接将其当做一个特殊字符就可以了。
但是我们要掌握一点，就是在雅思阅读的学术类或实验类文章中，subject是绝对的高频，且会被用作【实验对象】这个意思，volunteer或participant可作为其替换对象。
还有一些常见单词，但是有我们不知道的用法，环球君也已经整理好啦~
其实雅思中的一词多义情况还有很多，想完全掌握，最好的方法之一当然是大量做题，或者你可以点击我们的【阅读原文】来参加我们的真题模考，通过模拟考试来真实检测自己的雅思水平与理解能力，发现不足，尽早提分！
