A windsock is that orange or striped cloth tube on a pole that you see beside a runway. It is open at both ends, so wind blows straight through it and it swings round to point away from where the wind is coming from.

A windsock iswindsock是 that orange or striped cloth tube on a pole立在桿子上的那種橘色或有條紋的布筒 that you see beside a runway你會在跑道旁邊看到 It is open at both ends它兩端都是開口的 so wind blows straight through it所以風會直接穿過去 and it swings round to point away from where the wind is coming from然後轉過去，指向風吹來的相反方向

Pilots read it at a glance: the direction it points tells them which way the wind is going, and how full and how flat it stands tells them roughly how strong it is — hanging limp means still air, sticking straight out means a strong wind.

Pilots read it at a glance:飛行員看一眼就能讀懂它 the direction it points tells them which way the wind is going它指的方向告訴他們風往哪裡吹 and how full and how flat it stands tells them roughly how strong it is而它鼓起或垂下的程度，大概告訴他們風有多強 hanging limp means still air軟軟垂著就是沒有風 sticking straight out means a strong wind直直伸出去就是強風

You also see them at small airfields, at chemical plants (so people know which way a gas leak would drift), on bridges, and on highways in windy places. In English the word is sometimes used lightly for anything that flaps and fills with air the same way, and people joke about a thin person in a big coat looking like a windsock, but that is not fixed idiom, just play.
