六. 指代不清（Ambiguous Reference of Pronouns）

       指代不清主要講的是代詞與被指代的人或物關系不清，或者先后所用的代詞不一致。試看下面這一句：

       Mary was friendly to my sister because she wanted her to be her bridesmaid.

       （瑪麗和我姐姐很要好，因為她要她做她的伴娘。）

       讀完上面這一句話，讀者無法明確地判斷兩位姑娘中誰將結婚，誰將當伴娘。如果我們把易于引起誤解的代詞的所指對象加以明確，意思就一目了然了。這個句子可改為：

       Mary was friendly to my sister because she wanted my sister to be her bridesmaid.

       例1. And we can also know the society by serving it yourself.

       剖析：句中人稱代詞we和反身代詞yourself指代不一致。

       改為：We can also know society by serving it ourselves.

       七. 不間斷句子（Run-on Sentences）

       什么叫run-on sentence？請看下面的例句：

       例1. There are many ways we get to know the outside world.

       剖析：這個句子包含了兩層完整的意思："There are many ways." 以及"We get to know the outside world."。簡單地把它們連在一起就不妥當了。

       改為：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. 措詞毛病（Troubles in Diction）

       Diction是指在特定的句子中如何適當地選用詞語的問題。囿于教學時間緊迫，教師平時在這方面花的時間往往極其有限，影響了學生在寫作中沒有養成良好的推敲、斟酌的習慣。他們往往隨心所欲，拿來就用，所以作文中用詞不當的錯誤比比皆是。

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

       （農業方面化學物質使用的不斷增加也造成了污染。）

       剖析：顯然，考生把obstacles“障礙”，“障礙物”誤作substance“物質”了。另外“the increasing use（不斷增加的使用）” 應改為“abusive use（濫用）”。

       改為：The abusive use of chemical substances in agriculture also causes/leads to pollution.

       九. 累贅（Redundancy）

       言以簡潔為貴。寫句子沒有一個多余的詞；寫段落沒有一個無必要的句子。能用單詞的不用詞組；能用詞組的不用從句或句子。如：

       In spite of the fact that he is lazy, I like him.

       本句的"the fact that he is lazy"系同謂語從句，我們按照上述“能用詞組的不用從句”可以改為：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：整個句子可以大大簡化。

       改為：Diligent, caring people use money only to buy what they need.

       十. 不連貫（Incoherence）

       不連貫是指一個句子前言不對后語，或是結構上不暢通，這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與逗號后的it不連貫；It 與things在數方面不一致。

       改為：Fresh water is the most important thing in the world.

       十一. 綜合性語言錯誤（Comprehensive Misusage）

       所謂“綜合性語言錯誤”，是指除了上述十種錯誤以外，還有諸如時態、語態、標點符號、大小寫等方面的錯誤。

       例1. Today, Money to everybody is very importance, our's eat, cloth, live, go etc.
