fficeffice" />    

这ground 为何不用过去氏呢?

    

Even a police car is not allowed to speed (despite) in case of emergency, or else the driver is to be equally fined.

    

除了改成Except 还可以换成 despite of ?

Difficult 改成difficulty…

但请问 in communication 是各名词词组 不是应该以 difficult 去形容吗?

还是因为in communication属于定语呢?
