To overreact is to answer something with too much feeling, or by doing something the problem did not need. A small delay, a short message, a tiny mistake — and someone shouts, panics, or makes a huge new rule. Parents, bosses, and friends all get accused of this.

To overreact overreact（反應過度） is是 to answer something with too much feeling用太強烈的情緒去回應一件事, or by doing something the problem did not need或做出這個問題根本不需要的事。 A small delay一個小小的延誤, a short message一則短短的訊息, a tiny mistake一個小小的錯誤 — and someone shouts, panics, or makes a huge new rule然後有人就大吼、驚慌，或訂出一條全新的大規定。 Parents, bosses, and friends父母、老闆和朋友 all get accused of this都會被說犯了這個毛病。

It is everyday English, a little critical, not very formal. The “too much” is in the size of the feeling or the size of the action. The first problem can still be real.

It is everyday English這是日常英文, a little critical帶點批評意味, not very formal不太正式。 The “too much” is in the size of the feeling or the size of the action「太過」指的是情緒的大小，或行動的大小。 The first problem can still be real原本那個問題還是可能是真的。

Though actually, what counts as too much depends on who is speaking. The person who overreacts often feels they are only being careful; the other person feels the storm is too big for the rain. You will also hear it about groups and governments, not only about one angry moment.

Though actually不過實際上, what counts as too much depends on who is speaking什麼算「太過」，要看是誰在說話。 The person who overreacts often feels they are only being careful被說反應過度的人常常覺得自己只是小心; the other person feels the storm is too big for the rain另一個人卻覺得這場風暴比那場雨大太多了。 You will also hear it about groups and governments你也會聽到它用在團體和政府身上, not only about one angry moment不只是講一個生氣的瞬間。
