The FBI is a US police body that works for the national government, not for one city or state. The letters stand for Federal Bureau of Investigation.

Their work is crimes that break national law or cross state lines: some kinds of fraud, kidnapping across states, terrorism inside the country, and spying. A city police department handles a street fight; the FBI steps in when the crime is “federal.” Films show dark suits and a badge, and that picture is only half true — a lot of the work is slow: interviews, records, and waiting.

Their work他們的工作 is是 that break national law違反國家法律 or cross state lines或跨越州界的 crimes罪案： some kinds of fraud某幾種詐欺、 kidnapping across states跨州綁架、 terrorism inside the country境內恐怖活動 and spying和間諜活動。 A city police department市警局 handles處理 a street fight街頭鬥毆； when the crime is "federal"當案件屬於「聯邦」的時候， the FBI就輪到 FBI steps in出場。 Films電影 show演的是 dark suits深色西裝 and a badge和一枚警徽， and that picture而那個畫面 is only half true只有一半是真的 — a lot of the work很多工作 is slow很慢： interviews訪談、 records查紀錄 and waiting和等待。

People outside the US, including in Taiwan, sometimes say “FBI” as if it meant all American police. That is loose talk. Local police, state police, and the FBI are different offices.

outside the US美國以外的 People人， including in Taiwan包括在台灣， sometimes有時候 say "FBI"說「FBI」， as if it meant彷彿它是指 all American police所有的美國警察。 That那 is loose talk是講得鬆了。 Local police地方警察、 state police州警 and the FBI和 FBI are different offices是不同的機關。

The CIA is different again: that one is more about intelligence, much of it overseas, not ordinary crime on a US street. Though actually the edges have blurred a little in the last twenty years, the school picture still helps: FBI = federal crime, mostly inside the country.

The CIA又 is different again是另一回事： that one那一個 is more about比較是在做 intelligence情報， much of it overseas其中很多在海外， not不是 on a US street美國街頭的 ordinary crime普通犯罪。 Though actually不過其實 in the last twenty years過去二十年 the edges邊界 have blurred a little已經糊了一點， the school picture學校教的那張圖 still helps仍然有用： FBI = federal crime FBI＝聯邦罪案， mostly inside the country大多在國內。
