1.     主题句原则

书面表达一定有主题句，否则就会给人造成“群龙无首”的感觉！把主题句写在文章的开头（保险型），让别人一目了然。如：Now, I want totell you something about my life at Senoir High school.

In the past fewyears, great changes have taken place in the means of communication. In the past, weused to write letters….. 总说“改变”——分说 (先写“过去”，然后写“现在 ”进行对比)

2.     一二三原则

老师阅卷必然会通过关键性的“标志”，来看你的作文是否要点齐全，结构清楚，条理自然。要点齐全，一目了然，自然会增加“印象分”。方法很简单，选用以下其中一组，加在要点前。

（1）      first, second, third, last

（2）      firstly, secondly, thirdly, finnally

（3）      in the first place, in the second place, in the third place,lastly

（4）      to begin with, then, furthermore, finally

（5）      to start with, next, in addition, finally

（6）      on one hand, on the other hand

（7）      for one thing, for another thing

3.     短语优先，多实少虚原则

1) 写作时，使用短语有两个好处。其一，为文章增加亮点——又可以为作文加分！其二，字数明显增加。

I cannot bear it.  可以用短语表达为：  I cannot put up with it.

I want it.       可以用短语表达为：  I am looking forward to it.

2) 写作文应该写一些实际的东西，不要空话连篇。比如我们说一个人好的时候， 不应该只说good, nice这样空洞的词，应该使用形象一点，具体一点的词,诸如 generous,humorous, interesting, smart, gentle, warm-hearted, etc.

常用过渡短语：1）作比较： on the other hand,on the contrary, in/ by contrast, compared with,

2）做总结： to sum up, in conclusion, in brief,generally speaking

4. 句式多变原则

1) 并列（串联）

最保险的写长句的方法就是在任何句子之间加 and, 但最好是前后句子有先后关系&并列关系。比如：

I enjoy music and he is fondof paying guitar.

诸如此类的短语： not only …but also…, besides, furthermore

2)转折（拐弯抹角）

写作文的时候，只要在要点之前先来点废话，注意二者之间用转折就够了。但切记，废话不能长！

The coat was thin, but it waswarm.

诸如此类的短语：despite, still, however, in spite of, nevertheless

3) 因果（so）我们写作文讲故事，都应该讲究先后顺序。

The snow began tofall, so we went home.

诸如此类的短语：then, therefore, as a result, so that, consequently,thus

4）失衡句（头轻脚重&头重脚轻）

文章中如果出现这样的句子，就会让人觉得你英语功底深厚。失衡句实际上就是主语从句，表语从句，和宾语从句。比如：This is what Ican do.            Whether he cango with us or not is uncertain.

5．善用句型

1）S + is / was +adj.最高级+ 名词 + (that) +完成时     That/ This/ It + is/ was +序数词+ that 完成时

2）使用强调句.  It + be 被强调对象 + that / who + 剩余部分

3）The + 比较级 +S +V, the + 比较级 +S +V　（愈...愈...）The harder you work,the more progress you make.

4）Nothing is + adj.比较级+ than to + V（没有什么比...）Nothing is more important than to receive education.

5）It is time + S + 过去式（该是...的时候了）   It is time thegovernment took proper steps/ measures.

6）★   There is noneed/ good / use to do sth. 做某事没有必要/ 好处/ 用处  

Itis no no need/ good / use doing sth. 做某事没有必要/ 好处/ 用处

Thereis no point/ sense in doing sth.  做某事没有意义 
7）An advantage of ~~~ is that + 句子 （...的优点是...）

★ 词组联想：makethe most /best of, take davantage of, make full use of 充分利用…..

8）That is the reason why　~~~　（那就是...的原因）　 Summer is hot.That is the reason why I don't like it.

9） So + 形容词 + be + 主词 + that + 句子 （如此...以致于...）So precious is time that we can't afford to waste it.

10）As everyone knows,…./ As is known to all, ……(众所周知……)

★    词组联想：as far as I know/ am aware ，…… 据我所知，……

            as faras I am concerned/ in my opinion / as for me，…… 就我而言，……

11）  do goodto sb./sth.（对...有益）             do harmto sb./sth.（对...有害）　   
12）have a great influence/ effect on　~~~　（对...有很大的影响）　

13）感叹句：Whata + Adj + N + S + V!= How + Adj + a + N + V!（多么...！）　

注意事项：1）不能“漏点”2）紧扣每个要点，不能“废话连篇”3）禁忌把几个要点写在一个句子中。

4）打草稿时，多问自己 “① 这个句子是否有100%的把握不会错？② 能不能把句子换得更高级些？”
