sit的现在分词：在不同语境中的运用与理解

原文“他们压着我的申请不办有一个月了。”中“压着我的申请不办”语义不明，存在错误，不符合语法规范，应改为“他们已经把我的申请压了一个月了。”

因此，原文句子应改为：

They have been sitting on my application for a month now.

“压着我的申请不办”语义不明，存在错误，不符合语法规范，应改为“They have been dragging their feet on my application for a month now. ”

改写后的句子为：

"They have been dragging their feet on my application for a month now, delaying its processing."
