Explain!! need it fast

I think the "work" in this context may mean 作品 or 藝術品. Therefore, the sentence should be translated to:

請識別與指出這作品所表達的情感.

The verb "communicate" can mean 通信 ,轉達 or 溝通. However, within this context, I think the chinese sentence is closer to the orignal meaning if we translate it to 表達.

我相信這句的意思－－－你的工作是需要識別情緒溝通

唔好意思－－－我希望ｈｅｌｐ　到你啦
