the press would have a field day...怎么翻译呢

have a field day 英文释义：
to have an opportunity to do a lot of something you want to do and enjoy a great deal,especially to criticize someone.（有机会做想做/喜欢的事,特别是指责别人.）
例句：The newspapers would have a field day if their affair ever became public knowledge.
（如果他们的恋情被公开,报纸又将大作文章了.）
这里的翻译只能意会,根据语境才能具体翻译,本句可以翻译成：媒体对...事件大作文章.

没有语境啊 可以理解为：媒体们又要忙活一整天了
或是：他们对此很很满意

媒体忙活了一整天啊.
have a field day---忙了一天,痛快地玩了一阵子

have a field day 是固定词组，表示非常愉快。
the press would have a field day
新闻界（对此）很满意。
