这里应该是副词,作状语,修饰动词write.类似用法见如下例句：
I must have added it up wrong.
那我一定是加错了.
It looks like it's spelled wrong...x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05
看起来像是拼错了.
I can see exactly where he went wrong.x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05x05
我知道他究竟错在哪儿了
祝你开心如意!
