帮忙看一下这句话语法哪里错误了
Further,they will be bored to death and don't know what to do when they leave their phones or their phone batteries run down because they are no longer able to adapt to the life without phone.

优质解答

语法方面的问题：
1.they will be bored to death and don't know - don't 应改为won't 这里and连接并列结构,时态应该一致
2.or their phone batteries - 有歧义.不明确是their phone batteries和phones并列还是前后两个从句并列,建议改为or when their phone batteries run down
