常见的语法错误包括逗号错误、撇号错误、句子碎片、连缀句和错位修饰语。所有这些错误都会导致写法不清晰和语法错误。

逗号:
 
  逗号拼接是最为常见的，将语句进行连接。

   I have to run to the store, then I am going to the gym to workout.

  若要修复此错误，作者必须添加连接词、半冒号或添加句点，并单独创建一个句子：

   I have to run to the store, and then I am going to the gym to workout.

   I have to run to the store; then I am going to the gym to workout.

   I have to run to the store. Then, I am going to the gym to workout.

  当发布生日信息时，正确的格式是：

   Happy Birthday, Ralph!

  一个逗号应该放在人的名字和信息之间，因为是直接称呼那个人。

撇号:

  撇号错误也是常见的。撇号用来表示所有格，表示某些词是复数，并表示字母丢失。

  撇号表示拥有:

   Jim's coat (singular possession)

   The children's clothes (possession for plural noun that does not end in s)
 
   The dogs' toys (possession for plural nouns that end in s)

  Jim and Ted's apartment (possession shown on the last noun)

  撇号也用在缩写中以显示缺少的字母和数字：

   Can't (cannot)

   I'm (I am)

   Who's (Who is)

   ‘70 (1970)

句子:

  句子片段是另一种常见的语法错误：

   Fragment: Because I wanted the ball.

   Sentence: Because I wanted the ball, I ran down the hill.

   Sentence: I ran down the hill because I wanted the ball. (Notice that no comma comes before because when the phrase is within the sentence).

   Fragment: Or take the car.
   Sentence: Take the train or take the car.

  在大学写作课上，接续句是一个严重的问题：

   Run-on: I went to the park to run Sarah was there so I talked with her for a little while and we went to have some lunch.

   Correction: I went to the park to run. Sarah was there, so I talked with her for a little while, and we went to have some lunch.

所有权

  放错位置的修饰语也是很常见的语法错误：

   Incorrect: The girl smiled at the camera holding the basket of fruit. (The camera was holding the basket of fruit?)

   Correct: Holding the basket of fruit, the girl smiled at the camera.

  选择正确的单词形式

   Their: a possession

   They're: They are

   Whose: related to a possession

   Who's: who is
