复合形容词 用法
下列句子：
There are time-sensitive matters with this case.
这个案子在时间上有些棘手.
其中“time-sensitive"是复合形容词,请问是否可以这样用呢：
It is time-sensitive to go back home. ?从语法上怎样解释?
2,He know if we miss our filing deadline, we don't stand a chance to compete against them for the bid.
他知道如果我们错过了诉讼的最后期限,我们将没有机会和他们竞标了.
其中“filing"是什么意思?从语法上怎样理解?
3,Everything that came in off the fax machine last night is all on your desk.
请从语法角度分析句子成分.
It is time-sensitive to go back home.
我想知道的是，是否能够这样用。因为本人没有见过复合形容词接 to 的情况。
