The plane was moving unsteadily through the air, and although the passengers had fastened their seat belts, they were suddenly【C4】______forward. At that moment, the air-hostess appeared.

After a moment【C8】______ , a man got up and followed the hostess into the pilot’s cabin.

【C19】
选项 A、as
B、unless
C、while
D、so
答案A
解析 语法知识。本句意指当飞机接触到地面的时候，颠簸得很厉害。as意为“当……的时候”，符合句意。unless意为“除非”，引导条件状语从句，相当于if not的用法，用一般现在时代替将来时，如：My baby sister never cries unless she is hungry。while意为“当……时”，so意为“因此”，表结果，均不符合句意。
