首先，我们要背下这几种句子类型。因为无论你写什么作文 都会用到以下这几种句子。

　　1. 结果类

　　exert A on B

　　A-a great impact/ a positive influence/ a negative impact

　　Eg: Family education may exert a great impact on children’s behavior.

　　对于结果类的句子大家都习惯用“have a great impact/a positive influence on”很少用“exert a great impact/ a positive influence/ a negative impact on”，如果大家以后关于结果类的句型都用“exert”这个单词，是不是给自己的作文加分了呢?

　　2. 见证类

　　The past several years have witnessed .......

　　Eg: The past several years have witnessed an exponential increase in the number of cars.

　　在写作文的时候我们经常会用到一些背景句，我们在写这一类句子的时候往往会用人作主语，而更为地道的英语，往往都是用时间作主语，我们也会在经济学人期刊经常看到类似的表达: The past several years have witnessed an exponential increase in the number of parents who wish to send their kids to art classes.

　　3. 重要类

　　Nothing is more important than...

　　Sth plays quite an important role in...

　　Eg: Nothing is more important than to protect the environment.

　　Math,to some extent, plays quite an important role in students’ examination.

　　4.引出类

　　There is much controversy over the issue of...

　　Sth has given rise to a heated discussion.

　　Sth has caused quite a stir among the general public.

　　As regards sth, there has been a heated discussion among the general public.

　　Opinions vary greatly when it comes to sth.

　　其次，英语作文要注意衔接词的添加，弄清两个句子之间存在的逻辑关系。中国人写文章比较含蓄，注重意境与内隐，如：“我没去上学，我感冒了。”

　　而外国人注重简明易懂。如：“I did not go to school because I got the cold.”所以，我们受母语影响，会忘记衔接词的使用。在这里老师给大家总结一下链接词的使用方法：

　　1. 一般情况下，两个句子之间，只要不存在转折关系，没事就使用“and”。

　　Eg: I have two kids, and both of them are very clever and cute .

　　2. 表示原因的句子，要用“because/ because of/ in that/due to/ for/ since等。

　　Eg: I did not go to school because I got the cold.

　　3. 表示递进的句子，要用“furthermore/ what’s more/ moreover等。

　　Eg: To begin with, it goes without saying that science and technology has exerted a positive impact on the progress of civilization in the courses of our history. Furthermore/What’s more/Moreover, science and technology allows us to broaden one’s horizon....

　　4. 表示转折的句子，要用“but/however/yet/nevertheless/ by contrast/while等。

　　Eg: Some people maintain that praise should be given to the wealth because they contribute to charity business. While others take it for granted that......

　　然后，单词的多样性，难度。

　　1. 单词的多样性。

　　在作文中要多用同义转换，这样会让阅卷老师觉得你的词汇量很大很丰富。

　　Eg：people in growing numbers take it granted that taking exercise everyday is beneficial to our body, nevertheless, others maintain that work out, to some extent, might exert a negative influence on ours.

　　这里的 “taking exercise” 和“work out”为同义转换都是锻炼的意思。

　　2. 短语替代单词

　　Make a decision 替代decide

　　3. 单词的难度

　　同样是表达做某事很重要，有低级的表达也有高级的表达，所以大家要用些高级词汇替代低级词汇。

　　低级版：it is important that....

　　高级版：it is vital/ of great importance/ significant that...

　　最后，句子的多样性和长度。

　　1. 句子的长度，定语从句，名词性从句，状语从句，并列词拉长句子。

　　低级版：some people believe that the wealth have become rich can not leave the others in the society. They should contribute to the society.

　　高级版：Those people who hold the first opinion believe the wealth can not get rich without others in the society and they should feedback the society.

　　这里用一个定语从句修饰people，用并列连词不仅拉长了句子而且丰富了句子的多样性，contribute to 和 feedback 为单词的同义转换。

　　2. 功能句的应用和主动变被动

　　低级版: About these two ideas, I agree the latter one. For one thing, the wealth get their money because they work honestly and legally.

　　高级版：weighing up these two arguments, I am inclined to the latter one.For one thing,the wealth’s money is gotten by their honest and legal business.

　　背景为绿色的为功能句的使用，红色阴影的为主动变被动。

　　3. 虚拟语气倒装句的使用等。

　　It is high time that we are supposed to...

　　Only in this way can we ....

　　综上所述，要想写好作文，首先，多积累句子的类型，其次注意连接词的使用，然后单词的使用，包括同义转换，高级词汇替代低级词汇，最后句子的长度和多样性。
