今天我们要学习的词语跟“火”有关。

　　它就是on fire。

　　On fire这个短语的确有“着火”的意思。例如

　　The house was on fire for nearly an hour before the fire department finally arrived.

　　房子着火将近一个小时，消防队才赶来。

　　但是，在某些特定的场景中，on fire就不是它原本的意思了。尤其是表示某人的时候。

　　通常情况下，这种用法一般都用于文艺/体育活动中，表示“表现好”、“状态好”。

　　The team has been on fire lately, winning 11 of its last 12 games.

　　这支队伍最近状态非常好，赢下了12场比赛中的11场。

　　Having an intense burning sensation.

　　例如：

　　My legs are on fire after that workout!

　　运动之后，我的腿有一种灼烧感。
