同意替换
很多同学会有疑惑，为什么我已经背了模版，整理了文章思路，作文分数还是不高？最近来7plus分析成绩单的同学，发现写作分数不高通常伴随着Vocabulary分数很低。词汇分数在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）
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.
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。
to monitor people →the people are 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)
work for the same organization→remain in 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）
have more opportunity to study abroad→have many more options regarding how and where to acquire knowledge. （同义转换）
practical degree courses→science, engineering or media (意义具体化拓展)
philosophy and history→arts subjects文科 (意义概括化拓展)
好，下面我们结合具体题目, 来看一看在Introduction中如何综合运用以上方法吧。其他段落做法一致。
1.Some people workfor the same organization all their working life. Others think that it is better to work for different organizations.
改写后：
For most people, when they get their first job they have little idea whether or not they will remain in the same organization throughout their working life. If they decide to change, they need to consider how this will impact on their career overall.
2. One of the consequences of improved medical care is that people are living longer, and life expectancy is increasing. Do you think the advantages of this development outweigh the disadvantages？
改写后：
Over the past 50 years, people have become used to the idea that they will probably live longer than their grandparents did. However, a longer life is only desirable if you can look after yourself and be independent, otherwise there can be disadvantages for everyone.
3. Car ownership has increased so rapidly over the past thirty years that many cities in the world are now “one big traffic jam”.
改写后：
Most people would agree that car ownership has increased in recent years and is causing a range of problems, particularly in built-up areas.
4. In some countries, an increasing number of people are suffering from health problems as a result of eating too much fast food. It is therefore necessary for governments to impose a higher tax on this kind of food.
改写后：
The growth of the fast food industry has, without doubt, impacted on the eating habits and the health of many societies around the world. Diabetes, high cholesterol, heart and respiratory problems are allon the rise due to fatty and sugar-rich food. However, the question is whether higher tax would improve this situation or not.
5. In the past, when students did a university degree, they tended to study in their own country. Nowadays, they have more opportunity to study abroad.
改写后：
The pursuit of knowledge is a concept that is valuedby most cultures. In the 21st century, we now have many more options regarding how and where to find that knowledge.
