请问:"The authorization letter was ready and has sent it to your office before.
我想表达的是:委托函已经准备好并且寄过去给你了.
请问:"The authorization letter was ready and has sent it to your office before.我想表达的是:委托函已经准备好并且寄过去给你了.
用了and,后面没有主语表示和and前一句话公用一个主语,所以and后面主语是letter,那么就不要用sent了,可以写成and has already been sent to your office.before用在过去完成时.
不对。
后半句应该用被动语态，has been sent to your office.befor可以直接去掉，因为has已经包含了送去动作完成的意思，另外，可以把前半句想表达的意思告诉我吗？
可以了。
