书面表达旨在考查学生的英语表达能力，即运用学过的英语知识和掌握的技能进行思想交流的能力。现在的书面表达，实质上是一种控制性(controlled writing)或指导性写作(guided writing)，它不得离开要求去自行立意、随意发挥;它类似于“翻译”，又比 “翻译”有较大的灵活性。它只是在指定范围内比较灵活的写作。它要求学生根据所给的情景和要求写出一篇文理通顺、语言准确、连贯流畅、地道得体的短文。所以学生只有掌握住一定的写作技巧，才能使写出的作文内容完整，语言准确、生动而富有变化，行文流畅，才能获取高分。那么如何才能写出一篇优秀的书面表达呢？方法有如下三种：
一．短话长说
 近几年全国高考的书面表达所提供的信息越来越简单，呈现半开放的命题方式，这既是对新课程理念的响应，也是30多年探索的必然选择，这样给同学们提供了更大的发挥空间，但也提出了更高的要求。如果仅仅简单地翻译提纲所给信息，文章就显得单调无味，连字数都达不到要求，当然拿不到高分。这时我们就可以采用“长话短说”的方法。所谓 “短话长说”，就是要对所给信息进行合理，有效地补述和追述，通过适当添加成分，使你的书面表达更加连贯，饱满。
1.添加与所给信息有关的前因后果及条件，目的，时间，地点等内容,
例如：1）咖啡屋(Bolton Coffee)见面取消
 拓展：因为我有一个重要活动要参加。 （原因状语）
Tracy called，saying that she couldn't meet you at Bolton Coffee tomorrow morning. as she would have something important to attend .
2）我们希望你能接受我们的邀请。
 拓展：如果你方便的话。（条件状语）
We hope that you will accept our invitation if it is convenient for you.
3）我想找一位英国笔友。
 拓展：以便提高我的英语水平.。（目的状语）
I want to have an English pen friend in order to improve my English.
2. 举例说明或适当添加细节。
例如：1）我们有许多共同爱好。
We have a lot of common interests, such as travelling, swimming, fishing.
2）我家住房宽敞。
 拓展：位于市中心/位于一个漂亮的小区。
We have a large and clean house, which lies in the centre of the city/a beautiful area of the city.
3.加谚语(Proverb) 添加的谚语要与所给信息有关.
We should focus our mind on our studies. As the saying goes, “No pains, no gains.”
4.为了突现文章的真实交际功能，适当表达自己真实情感
如开头用：I’m glad/sorry to say…
结尾用：
I would greatly appreciate it if…
I’m sure you will… 
It was quite an experience for us both, which I'll never forget for the rest of my life. … etc.
二．锤炼句子
 在书面表达中，能正确使用复杂句式，如，定语从句、名词性从句、状语从句、强调和倒装结构等，是语言驾驭能力的很好的体现，也是评卷老师判定高考英语书面表达档次的重要依据。因此，力求句子长短交错，合理穿插，结构多变，可以使句子更加漂亮，以增加文章的亮度。
1、改变句子的开头方式
句子不要一味都用主语开头，接着是谓语、宾语，最后再加一个状语。可以把状语置于句首，或用分词作状语等。
试比较：
The young man couldn’t help crying when he heard the bad news.
→Hearing the bad news, the young man couldn’t help crying.
2、在整篇文章中,避免只使用一两个句式。在一篇文章中,要灵活运用诸如强调句、主从复合句、分词短语、倒装句、省略句等。
The dog has saved my little sister bravely.    
→It is the dog that has saved my little sister bravely. （强调句）
We had to stand there to catch the offender.    
→What we had to do was to stand there，trying to catch the offender.
（主语从句、分词结构）
The driver escaped and didn’t stop，he left the old man lying on the road.    
→The driver escaped without stopping，leaving the old man lying on the road.
（介词短语、分词结构）
I went to bed at 11：30.    
→Not until 11：30 did I go to bed . （倒装句）
We had a short rest. Then we began to play happily. We sang and danced.
→After a short rest, we had great fun singing and dancing. （介词短语、分词结构）
三．巧用连词
 一篇好的书面表达，还应该行文连贯流畅，具有“逻辑美”。使用恰当连接词，能使文章上下衔接自然、紧凑，使文章更为地道，更具“英语味”。 有了这些词的连接，文章就会变得语句通顺，层次分明，有声有色，而不再是支离破碎的一个一个的单句。常用连接词如下：
1.表示并列或递进: and, as well, as well as, both…and, not only…but also, neither…nor;
2.表示选择: or, either…or;
3.表示转折: but, however, nevertheless, although, though, or else, otherwise, after all, by the way, incidentally;
4.表示因果: because, as, since, for, for this reason, so, as a result, thus, hence, therefore, accordingly;
5.表示条件: if so, unless, provided that, on condition that;
6.表示对比: while, whereas, instead, not…but, on the contrary, on the one hand…on the other hand;
7.表示解释: for example, for instance, such as, e.g., that is, that is to say, namely, viz, ie, in other words;
8.表示顺序:to begin with, for one thing, firstly, first (of all), second(ly), next, later, soon afterwards, since then, from then on, lastly, finally, in the end;
9.表示强调: also, besides, furthermore, moreover, what’s more, certainly, actually, in fact, as a matter of fact;
10.表示结论: to sum up, in all, altogether, in a word, in short, generally speaking, as is known to all.
 有了好的方法，再加上教师的耐心辅导，学生必然能打下扎实的英语基础。总之，全面提高书面表达的水平，离不开平时的点滴积累和不断磨练，这样才能达到理想的效果。
