今天一天改了一些学生的作文,丛冢发现了一些大家都犯的共性的错误,这里把它罗列出来,希望对大家以后写作有所帮助.
1.词性的错误使用，一般来说是名词和动词,形容词和名词词性区分不是很明确
We can analysis that high income group eats mire fast foods than the other two groups.
Children have a special curious.
2.句子中缺少动词，一般来说造成的原因有很多，
（1）句子过于复杂，主从句距离比较远，

Pizza’s consumption rising regularly from 40 grams to about 250 grams from 1970 to 1990.
3.Run-on sentences 在学生的作文中出现比较频繁
主要集中在there be 句型中

4.可数名词单复数的问题 （可数名词是不可以担负放置在句中）

5.academic writing中缩写问题（academic writing 中是不可以出现缩写形式的）
But we can’t ignore that the severity of violence on screen affections.
6.实际句子之间很少用连接词而直接把连个或者更多句子用逗号连接起来

7.句意表达不明确
The society increases crazy at present.
8.the的使用情况
government need take vigorous actions to tackle this problem.
在一些词语前面必须要加the，譬如government, environment, ecosystem etc.同时在一些情况下没有必要使用the 的时候也不需要乱用。
8.句子不完整，缺少成分 incomplete sentences

9.缩写形式的使用，在学术类写作中是不可以出现abbreviation的

10.使用从句时，注意句中主谓是否一致

11.被动与台的使用错误/ 动词的连续使用

13.文章中句式过于单一，尤其表现在图表作文中。
14.在首段表达不同的观点时，不需要使用过去时态，一般现在时就可以
