A 737 is a medium-sized passenger plane made by Boeing, a big US company. Airlines use it for trips that are not the longest in the world — a few hours, many cities, many flights a day. If you have flown in East Asia, there is a fair chance you have sat in one; you just may not have read the number on the outside.

A 737 is a medium-sized passenger plane made by Boeing737是波音做的中型客機，a big US company波音是一家美國大公司。Airlines use it for trips that are not the longest in the world航空公司用它飛不是全世界最長程的航線——a few hours, many cities, many flights a day幾個小時、很多城市、一天很多班次。If you have flown in East Asia如果你在東亞搭過飛機，there is a fair chance you have sat in one你有不小的機率坐過這款；you just may not have read the number on the outside只是你可能沒注意看機身上的號碼。

There is not one single 737. Boeing has built many versions for fifty-plus years, with different engines, different lengths, and different computer systems. News about a 737 crash or a grounded fleet is usually about one version, not every 737 in the sky.

There is not one single 737737並不是只有單一一種。Boeing has built many versions for fifty-plus years波音五十多年來做了很多不同版本，with different engines, different lengths, and different computer systems引擎不同、長度不同、電腦系統也不同。News about a 737 crash or a grounded fleet新聞講737墜機或機隊停飛的時候 is usually about one version通常指的是某一個版本，not every 737 in the sky不是天上每一架737。

Still, in ordinary talk “a 737” just means that familiar narrow Boeing jet. People around planes often say “seven thirty-seven” or “seven three seven.” It is a model name, as ordinary as a car’s name, not posh and not slang.

Still不過，in ordinary talk在日常對話裡 "a 737" just means that familiar narrow Boeing jet「a 737」就是指那種熟悉的波音窄體客機。People around planes often say "seven thirty-seven" or "seven three seven."常接觸飛機的人常說「seven thirty-seven」或「seven three seven」。It is a model name這是個型號名稱，as ordinary as a car's name跟車子的名字一樣普通，not posh and not slang不高級也不是俚語。
