改为：

　　there are many ways for us to learn about the outside world. 或：

　　there are many ways through which we can become acquainted with the outside

　　world

　　八. 措词毛病(troubles in diction)

　　diction 是指在特定的句子中如何适当地选用词语的问题，囿于教学时间紧迫，教师平时在这方面花的时间往往极其有限，影响了学生在写作中没有养成良好的推敲，斟酌的习惯。他们往往随心所欲，拿来就用。所以作文中用词不当的错误比比皆是。

　　例1. the increasing use of chemical obstacles in agriculture also makes pollution.

　　(农业方面化学物质使用的不断增加也造成了污染。)

　　剖析：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(redundancy)

　　言以简洁为贵。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。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.

　　例1. for the people who are diligent and kind, money is just the thing to be used to buy the thing they need.

　　剖析：整个句子可以大大简化。

　　改为：

　　diligent, caring people use money only to buy what they need.

　　十. 不连贯(incoherence)

　　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。

　　例1. the fresh water, it is the most important things of the earth.

　　剖析：the fresh water 与逗号后的it 不连贯。it 与things 在数方面不一致。

　　改为：

　　fresh water is the most important thing in the world.

　　十一. 综合性语言错误(comprehensive misusage)

　　所谓“综合性语言错误”，是指除了上述十种错误以外，还有诸如时态，语态，标点符号，大小写等方面的错误。

　　例1.today, money to everybody is very importance, our’s eat, cloth, live, go etc
