Ladies and Gentlemen, please remainuntil the plane has come to a complete stop.

A. seated

B. seating

C. to seat

D. seat

答案：

A. seated

B. seating

C. to seat

D. seat

解析：本题考查非谓语动词。句意：女士们，先生们，请在飞机完全停下来之后，再离开座位。remain 仍然是；保持不变，在这里是一个连系动词。seat：vt.用法：seat oneself；seat people；be/remain seated：保持坐着的状态，seated是由过去分词变来的形容词，作remain的表语，表状态。
