你可能已经有句子片段的错误。一个句子片段即是不完整的句子。它不表达一个完整的思绪，纵使它以大写字母开头和用一个标点符号结尾。它可能缺少一个主词或动词或两者兼缺乏。
这里有两个例子：
片段: Where there were mice and cockroaches.
片段: A movie that inspires deep emotions.
片段: Analyzing the characters' motives.
这两组字词不能单独作为完整的句子。有两种修改的方式。一种方式是附加片段至一个完整的句子：
修改后的句子: Peter left the apartment where there were mice and cockroaches.
修改后的句子: I went to see "The Silver Star," a movie that inspires deep emotions.
修改后的句子: Analyzing the characters' motives is central to understanding a novel.
另一种修改的方式是添加一个完整的主题，完整的动词，或其它的字以表达一个完整的思绪:
修改后的句子: This is where there were mice and cockroaches.
修改后的句子: A movie that inspires deep emotions is rare.
修改后的句子: Analyzing the characters' motives is important.
总结:句子片段即是不完整的句子。有时候读者可以藉由重读前一个或后一个句子来猜测句子片段的意思。可是，修改句子片段使它成为完整的句子可以增进思考逻辑间的关连。您可与您的指导教师请教，以查看您是否需要协助修改句子片段。
注意: 有时候，一个完整的句子可能看似一个子句，因为它在开头的文字群组之后遗漏一个逗号。当您用一个从属子句开始一个句子时，请记得在该从属子句之后打个逗号。
以下是一个因为错误的标点符号而看似子句的完整句子之例子：
错误: If we have enough time this weekend we'll go to see the cherry trees in bloom.
在此句子中， "...we'll go to see the cherry trees in bloom"是一个可以独立存在的独立子句。"If we have enough time this weekend"是一個不可独立存在的从属子句。使用一个逗号來分开开头的从属子句及独立子句：
正确: If we have enough time this weekend, we'll go to see the cherry trees in bloom.
连写句
您可能有连写句。连写句指的是两个主句之间不用连接词或错用标点的句子。连写句可能使人非常困惑。例如: My sister loves to dance she is very good at it。
修改连写句有些不同方式:
1. 把连写句分成两个独立的句子。
连写句: My sister loves to dance she is very good at it.
修改后的句子: My sister loves to dance. She is very good at it.
连写句: Jim showed us his ticket someone gave it to him.
修改后的句子: Jim showed us his ticket. Someone gave it to him.
2. 使用对等连接词或标点来连接连写句中的不同部分。以下是常用的对等连接词: and, but, for, nor, or, so, yet。
连写句: My sister loves to dance she is very good at it.
修改后的句子: My sister loves to dance, and she is very good at it.
连写句: She agreed to chair the meeting she didn't come.
修改后的句子: She agreed to chair the meeting, but she didn't come.
3. 使用从属连词来连接连写句中的不同部分。
以下是常用的从属连词: after, although, as, because, before, if, since, unless, until, when, whereas, while。
连写句: My sister loves to dance she is very good at it.
修改后的句子: My sister loves to dance because she is very good at it.
连写句: Maria and John like skiing Karen does not.
修改后的句子: Although Maria and John like skiing, Karen does not.
4. 使用分号来连接连写句中的不同部分。
连写句: Gordon laughed at Sandy's joke it was funny.
修改后的句子: Gordon laughed at Sandy's joke; it was funny.
连写句: I thought he was here I was wrong.
修改后的句子: I thought he was here; I was wrong.
连写句: My sister loves to dance she is very good at it.
