八、措词毛病
学生在写作中没有养成良好的推敲，斟酌句子中所选用词的习惯。大部分考生随心所欲，拿来就用，所以作文中用词不当的错误随处可见。比如：The increasing use of chemical obstacles in agriculture also makes pollution.
分析：显然，考生把obstacles“障碍”，“障碍物”误作substance“物质”了。另外“the increasing use(不断增加的使用)”应改为“abusive use(滥用)”。
改为：The abusive use of chemical substances in agriculture also causes/leads to pollution.
九、累赘
写句子没有一个多余的词;写段落没有一个无必要的句子。能用单词的不用词组;能用词组的不用从句或句子。比如：In spite of the fact that he is lazy, I like him.
本句的“the fact that he is lazy”系同谓语从句，我们按照上述“能用词组的不用从句”可以改为：In spite of his laziness, I like him.
比如：For the people who are diligent and kind, money is just the thing to be used to buy the thing they need.
整个句子可以大大简化为：Diligent people use money only to buy what they need.
十、不连贯
不连贯是指一个句子前言不对后语，或是结构上不畅通，这也是考生常犯的毛病。比如：The fresh water, it is the most important things of the earth.
分析：the fresh water与逗号后的it不连贯，it与things在数方面不一致。
