中考英语书面表达对比类写作
对比类写作已成为英语书面表达中一个非常重要的形式。不管在工作学习中还是在日常生活中，对比是人们分析问题和解决问题的重要方法和手段，这就不难理解为什么对比类写作中考写作中的一个重要形式。
对比类写作一般有两种方式：一是集中比较或对比（集中说明一个对象的诸种特征）；二是逐点比较或对比（一条一条地说明两者的异同）。
对比类写作可以大致分为以下几种：
一、今昔对比
在作今昔对比时，要注意时态的变化。谈到过去的情况要用过去时态（主要是一般过去时），谈到现在的情况要用现在时态（主要是一般现在时）。
今昔对比的写作格式是：开头（提出什么事情发生了变化）→对具体事例作对比→结论。写作方式既可采用集中比较，也可采用逐点比较。在写作时可用以下句型来组织完成整篇文章：
1. 开头常用句型
(1) Great changes have taken place. 发生了巨大变化。
Great changes have taken place in my hometown in the last five year.
Quite a few changes have taken place in my school since you l eft China.
Over the past twenty years or so, great changes have taken place in our life.
(2) Things have begun to improve since… 自从……以来，事情有了好转/改善。
Things have begun to improve since schools were call ed on to reduce learning load.
2. 对比常用句型
(1) …used to…, but now… 过去常……，但是现在……
(2) …in the past, but now… 在过去……，但是现在……
(3) O nce…, but now… 曾经…….，但是现在……
(4) Things are different now. 情况已大不同了。
(5) But now, everything has changed. 但是现在全变了。
I used to have to work even at weekends d oing endl ess homework and attending classes as well, but now I have more free time.
在作对比时，为避免句型重复，可适当变换一些句式，比如：
(1) Another change is… 再有一个变化是……
Another big change is in the housing conditions.
(2) What’s more, … 还有……
What's more, I can go to bed earlier than in the past.
3. 结尾常用句型
In short, changes in our life in the past twenty years have brought us comfort and convenience. 例题：假设你是李华，在一所中学读书。最近收到美国朋友Smith先生的来信。他三年前参观过你校，听说现在变化很大，希望了解有关情况。参照下图，给他写一封信，介绍你校的变化。
注意：1.回信须包括图画的主要内容，可以适当增减细节，使内容连贯；
2.词数100左右。
范文:
Dear Mr Smith,
I was so pleased to hear from you and am writing to tell you something about my school. You are right. Quite a few changes have taken place. On one side of the road there is a new classroom building. On the other side, where the playground used to be, now stands another building --- our library. In it there are all kinds of books, newspapers and magazines. The playground is now in front of the school. We have also planted a lot of trees in and around the school. I hope you come and see for yourself some day,
Best wishes,
Yours,
Li Hua
二、正反观点对比
对同一件事情，人们常有不同的看法，即正反两种观点。在写作时，常使用一般现在时。写作格式一般是：提出问题→两种不同观点→对两种不同观点的论据（理由）逐项作对比。有时题目会要求说出自己的观点，可在结尾段加上自己的观点并简要说明理由，最好不要重复前面的已谈到的理由。写作方式一般采用集中比较。在写作时可用以下句型来组织完成整篇文章：正反观点对比常用句型
