Question

【题目】The pilot asked all the passengers on board to remain ____ as the plane was making a landing.

A. to be seatedB. seating

C. to be seatingD. seated

Answer 1

【答案】D

【解析】

考查非谓语动词。句意：飞行员让飞机上所有乘客在飞机降落时保持坐好。be seated 表示“坐着”，强调一种状态，这里的 remain 是系动词，remain seated 就相当于be seated，故用过去分词形式。故正确答案为D。
