词汇分数在PTE大作文中不是比重最大的，但是适当的选词不但给Vocabulary贡献分数外，对General linguistic range也能增色不少。但有的题目中关键词似乎并没有那么好替换，硬套的synonym一些情况下并不适合语境，反而别扭又绕口。今天我们来看几个通用的同义替换方法。
同义词替换
同义词替换是最常见也最容易学习的方法，需要我们在日常复习注意积累，才能在考试中无往不利。同义词替换一般以名词和形容词为主，我们首先来给出一些最常见的例子作为参考。
positive→beneficial,favorable,advantageous,promising,pleasurable
good→excellent, outstanding, superior
Important→essential,crucial,vital,pivotal,indispensable
Thing→affair, business, matter
Think→believe, reckon, advocate, allege
Very→exceedingly, extremely, intensely
Improve→enhance, reinforce, strengthen, fortify
除了单纯的同义词，我们还可以将名词词组换成相近内容的词或词组。
all their working life→throughout their working life(修饰词同义替换)
solarenergy→solar power(同义名词替换)
arts subjects→art courses(同义名词替换)
wild habitat→ecosystem
university fees→money on tertiary study(同义名词替换)
chances of employment→job opportunities(同义名词替换)
to monitor people→to keep the public under surveillance（动词转名词词组同义替换）
换词性、换语序
这种方法要对同源词组有一定的了解，能够做到正确替换。
Is more popular→is of the universalpopularity.(形容词—名词)
Aglobalized world→globalization(形容词—名词)
Solar energy is becoming more and more popular as a source of household energy→Solar power as asource of domestic household energy is becoming more desirable.
换语法
3.1）主被动转换
这是相对最简单省力的做法，但一定要确保语法正确。
tomonitorpeople→the peopleare monitored…
security cameras are increasingly being used to monitor what people are saying and doing.→security cameras are recording the movements of ordinary citizens
3.2)其它语法形式转变
people are living longer→people have become used to the idea that they will probably live longer (时态转变)
an increasing numberof people are suffering from health problems as a result of eating too much fast food.→The growth of the fast food industry has, without doubt, impacted on the eating habits and the health(因果关系转变)
同意转换或拓展
work for the same organization→remainin the same company （同义转换）
over the past thirty years→in recent years （同义转换）
Nowadays→In recent years→In the 21st century （同义转换）
In some countries→of many societies around the world （同义转换）
