Up in arms?

Arms這裡係用解 武器,軍火

Up in arms 解 武裝起來, 非常憤怒

例句-1: "All us students are up in arms at the news the school is raising our tuition ten percent."
這句話的意思是：“當我們學生聽到學校要提高百分之十的學費時，我們都火冒三丈。”

下面我們要舉的例子是一個國會議員在和一個同事談論新的稅收提案:
例句-2: "No way am I going to vote for a bill to raise income tax again. The voters back home are already up in arms about how much the government takes out of their pay already and I have to run for re-election this fall."
這位議員說：“我絕不會投票支援再次增加所得稅的提案。我們州的選民對政府現在從他們工資裏扣除的稅的數量已經非常惱火了。而我今年還要競選連任。”
