大多数的考生们想法是
1
常犯错误1：不一致
除了常说的主谓不一致，还有数的不一致、时态不一致及代词不一致等。
例子： The relationship between Ashiley and Suzan remaintense.
分析：本句主语是relationship 是单数第三人称，因而本句的remain应改为remains。本句是典型的主谓不一致。
改：The relationship between Ashiley and Suzan remainstense.

常犯错误2：词性误用
这类错误是考生最常犯的。 最经常能够看到的状况就是名词作动词用，形容词副词动词混用，介词当动词用。
例： None can negative the importance of money.
分析： negative 为形容词，不能当做动词使用。
改： None can deny the importance of money.

常犯错误3： 悬垂修饰语
悬垂修饰语指的是句首短语与后面句子的逻辑关系混乱不清。
例如：Hearing a number of entertaining stories, our visitwas enjoyable.
分析：在该句中，句首的“hearing a number of entertaining stories”与句子的逻辑关系混乱不清。这样的放置使得主语不明确，如果与后句公用主语“our visit”，则语义不通。
改：Hearing a number of entertaining stories，we enjoyed our visit.
来看另一个例子： when only several years old, my mother took meto a dance class.
分析： 同样“when only several years old”也是悬垂修饰语
改：When I was only several years old, my mother took meto a dance class.

常犯错误4：句子不完整
在日常口语交流中，身体语言与语气都可以帮助交际双方理解彼此想表达的含义，尽管句子不完整，但仍可以被理解与接受。可是写作中，句子结构不完整，往往会模糊语义，不能清晰的向读者呈现真实意思。
例子：There are many ways to know a man. For example byhis temper, his hobbies and so on.
分析：一个完整的句子包含明确的主谓宾。而本句后半部分“For example by his temper,his hobbies and so on.”是典型的不完整句子。对于这个句子可以附加在一个句子后面，用逗号隔开。
改：There are many ways to know a man, for example by histemper, his hobbies and so on.

常犯错误5： 指代不清
Mary was friendly to my sister because she wanted her to become her bridesmaid.
分析：整句话，指代不清，读完后，完全无法判断两位姑娘谁是伴娘。指示代词不恰当的使用会造成语义模糊。
改： Mary was friendly to my sister because she wanted mysister to become her bridesmaid.
