易错标点类型及例句
在英语写作中，正确使用标点符号极为重要。然而，很多人常常犯以下几种标点易错的类型，导致文章表达不清晰。接下来，我们将讨论这些易错类型以及提供一些例句帮助你更好地了解。
1. 逗号隔离从句
一个常见的错误形式是在从句之前或之后没有使用逗号，这导致从句的意思不清晰。请看下面两个例句：
Incorrect: Despite feeling tired I, finished my work.
Correct: Despite feeling tired, I finished my work.
Incorrect: She wanted to help her friend who was in trouble but couldn't find the right words to say.
Correct: She wanted to help her friend, who was in trouble, but couldn't find the right words to say.
2. 破折号表示强调
破折号是表示强调的一种标点符号。不幸的是，许多人误用破折号，而应该使用的是句中的逗号或分号。请看下面的例子：
Incorrect: I promised to do three things--to clean the bathroom, mow the lawn, and do the dishes.
Correct: I promised to do three things: clean the bathroom, mow the lawn, and do the dishes.
Incorrect: He was a great mentor--his advice was always helpful, and he was never too busy for his students.
Correct: He was a great mentor; his advice was always helpful, and he was never too busy for his students.
3. 句号和逗号的混淆
句号用于表示一个完整的句子结束，而逗号用于分隔句子中的成分。在某些情况下，这两者很容易混淆。请看下面的例子：
Incorrect: Walking to the store, I saw a dog that was playing with a ball.
Correct: Walking to the store, I saw a dog, which was playing with a ball.
Incorrect: I like cats, dogs, and birds. Especially birds.
Correct: I like cats, dogs, and birds, especially birds.
