在学习A-level经济学课程的过程中，最让同学们焦虑的部分应该就是essay部分了，尤其是在A2阶段，许多问题的方式是很多变的，很多学生不知道该怎么解答，今天我们以AQA考试局的往年真题为例，帮助同学们理理答题的思路和角度，想要拿高分的学生不要错过了哦~

AQA past paper:

Evaluate the potential impact on the economic growth of the UK economy if it were to adopt the single European currency.

一、拿到一个问题，先不要急着写，先分析一下问题的核心。我们看到问题的核心关键词包括：”evaluate”, “potential impact”,“economic growth”, “single European currency”等。

二、找到关键词接下来就要分析每个关键词所隐含的背后的意思：

evaluate：要求我们用动态思维来分析经济问题，在一定条件下理论上得出结论。但考虑到实际问题的特殊性，我们需要考虑当极限条件发生变化时，结论会发生怎样的变化。

potential impact：谈到影响，特别是经济学专业的学生，一定要用辩证的思维来看待问题。影响有好有坏，所以我们要分析事物的两面。优点是什么，伴随而来的缺点是什么，我们都需要讨论。

economic growth、single European currency：这两个词是文章的核心要点，是学生在写作前要记住可能会用到的要点。

三、通过对关键词的深入解读，就可以得出本文的总体框架。

1、讨论单一欧洲货币对英国经济增长的积极影响，结合英国的实际国情，分析每个利益点的效果程度。

2、运用同样的思想对其消极的影响进行深刻的分析。

3、综合前两部分的分析和讨论，对影响进行总结，明确是利大于弊还是弊大于利。

四、下面是针对此题，给出的参考例文：

The adoption of single European currency can benefit the economic growth of the UK economy.

Firstly, a single currency lowers transaction costs of trade, which promotes exports. The export is important to UK as it accounts for 60% of UK’s trade. Allowing for the existing low transaction cost between the UK and EU, a single currency will only have a relatively modest impact on increasing exports and its economic growth.

Then, a single currency helps stabilize the exchange rates. At the moment, UK exporters suffer from rapid appreciations in the exchange rate against the Euro.If UK joins the Euro,it will bring about greater stability, which encourages investment. However, many firms have already insure against exchange rate volatility. Therefore, the impact will not become very impressive.

Besides, a single currency might encourage foreign direct investment, which can boost both aggregate demand and aggregate supply.

The adoption of a single currency may also bring some side effects to the economic growth of UK.

The general interest rate set by ECB may not suit UK economy very well. For example, if the UK economy experiences a recession, but the rest of the Euro zone was still growing, interest rates are likely to be too high for UK, which means the economic growth of UK will suffer because higher interest rates would cause lower spending ad investment, worsening the recession.Also,many people have large variable mortgage in UK housing market, higher interest rates may have a big effect on reducing growth rates. On the other hand, if the UK economy is growing and inflation in Europe is low, interest rates may be kept low, which causes the UK economy to expand more quickly. Hence,problems like inflation and a housing boom may occur.

In conclusion,if the UK economy harmonies with the EU economic cycle,then UK economic growth would not be affected very much.

好了，今天就分享到这里，希望以上讲解能为同学们打开新的思路，essay的提高也是一个循序渐见的过程，需要大家不断地练习，最后希望大家都能拿到理想的分数~
