He is sitting at the desk.他坐在桌旁。
All the guests were seated in the sitting-room.所有的客人都坐在起居室里。
<辨析>这两个词都含“坐”的意思。sit 通常用作不及物动词，不需要宾语。如：
Come and sit here.来坐这儿。
In the bus we sat together.在公共汽车里我们坐在一起。
seat 通常用作及物动词，与反身代词连用或用 be seated 这一形式（这种用法不如sit普通）；seat还可作“能坐人”解，主语往往是地方。如：
I seated myself on the grass.我在草地上坐下。
Be seated,everybody!大家请坐吧！
That cinema can seat 2000 people.那家电影院能坐二千人。
