改错since then we have been good friends and now write English letters to each other.
问题描述：
改错since then we have been good friends and now write English letters to each other.
请问本句话有错误吗?since then引导现在完成时没错,但是后面直接now write,那不是变成了,since then we now write了吗?时态不对啊,觉的now 后应该加we
答
改错since then we have been good friends and now write English letters to each other.
可以改为：Since then we have been good friends and now we write English letters to each other.
Since then 我们可能不懂英语,但是,现在我们懂英语了,now we write English letters to each other.
