巧解高中英语作文中“逗号”和“句号”的使用
教学目标：
1. 认知“逗号误用”现象并学习修改方法。 2. 学习使用“连句”发改进“句号过多”的现象。 教学重点：
“逗号误用”的修改，“连句”的方法 教学步骤： 一．逗号问题
1. “逗号误用”现象举例
中文与英文的最大区别，在于中文句子是“意合”的，而英文句子是“形合”的，英语中，独立的两句话不能用逗号连接，句子之间必须有连词相连，构成并列句或者复合句。
e.g. It rained all night,the ceiling began to leak.( F ) 应改为： It rained all night,and the ceiling began to leak.
He worked harder,finally he failed again.( F ) 应改为： He worked harder,but finally failed again. 2. 针对“逗号使用”的修改方法
可以通过四种方法修改“逗号误用”的问题：即： 逗号变句号 逗号变分号 句子之间加连词 变成非谓语动词
e.g. The exam was postponed,the class was canceled. 考试推迟了，上课取消了。（F )
1
可以修改为：
The exam was postponed . The class was canceled . The exam was postponed ; the class was canceled . The exam was postponed , so the class was canceled . The exam was postponed , the class canceled . 3.Exercises:
1) I didn’t give up,I still kept writing. ( F ) 可以修改为: a:______________________________________________ b:______________________________________________ c:______________________________________________ d:______________________________________________
2) We were invited to Mr Smith’s last night,we enjoyed ourselves. ( F ) 可以修改为:
a:______________________________________________ b:______________________________________________ c:______________________________________________ d:______________________________________________ 二．句号问题。
有时两个或更多的句子，如果思想内容上关系很密，我们可以把它们连成一个句子，通过“连句”的方法，是文章意义更加连贯，结构更加紧凑，语言更加生动。
“连句”的方法： 1. 介词短语法
He didn’t write the letter himself.
2
He asked his friend to do it. 可以改写为:
Instead of writing the letter himself,he asked his friends to do it. 2. 并列连词法
1). He has given up smoking.
Now he is living a healthy life. 可以改写为： He has given up smoking and now living a healthy life. 2). I had failed many times.
I was confident that I would succeed in the end. 可以改写为 I had failed many times, but I was confident that I would succeed in the end. 3. 从属连词法
1). Some people are homeless.
We should do what we can to help them. 可以改写为： We should do what we can to help those who are homeless. ( 运用定语从句） 2). He suddenly fell ill last week.
This made us surprised. 可以改写为：
That he suddenly fell ill last week made us surprised. ( 运用名词性从句）
3
3). He was so sad.
He didn’t know what to say or what to do. 可以改写为： He was so sad that he didn’t know what to say or what to do. ( 运用状语从句） 4. 非谓语动词法
1). Most of them laughed at me .
They told me it was out of my reach . 可以改写为： Most of them laughed at me, telling me it was out of reach. 2). On national day he got up very early.
He wanted to watch raising national flag on Tiananmen Square. 可以改写为：
On national day he got up to watch raising national flag on Tiananmen Square.
3). Tom was addicted to playing computer games. He lost interest in study. 可以改写为：
Addicted to playing computer games , Tom lost interest in study. 5 同位语短语法 I am Li Ming.
I am a student from Shangshiqiao Senior High School.
4
可以改写为：
I am Li Ming , a student fromShangshiqiao Senior High School. 6. 独立主格法
Their children watched the buses passing through the village . Their eyes were bright and eager . 可以改写为：
Their children watched the buses passing through the village , their eyes being bright and eager . Exercises (改写句子）
