串句是指错误地将两个独立的分句串在一起，不用连词或标点符号连接。最常见的问题在于直接用逗号“,”连接两个意思完整的句子。如果将逗号用于完整的独立句之间，便会产生串句。例:
Mike decided to stop smoking, he didn’t want to die of lung cancer.
这个句子怎么修改，这里建议五种修改方法：
1. Mike decided to stop smoking, for he didn’t want to die of lung cancer.
2. Mike decided to stop smoking because he didn’t want to die of lung cancer.
3. Mike decided to stop smoking, not wanting to die of lung cancer.
4. Mike decided to stop smoking; he didn’t want to die of lung cancer.
5. Mike decided to stop smoking. He didn’t want to die of lung cancer.
