Once _____ in a theater wearing 3D glasses, you feel as though you are caught up in the story which is showing around you.

A．seated

B．be seated

C．to sit

D．have been sitting

答案

A

解析

试题分析：考查分词转换的形容词用法。动词seat使…就坐；能容纳；它的过去分词转换的形容词seated表示就坐的状态。可以修饰名词，对主语的情况进行说明。句意：一旦坐在剧院里，带上3D眼睛，你就会感觉到你身临一个发生在你身边的故事。故A正确。
点评：考查由分词转换的形容词的用法：这样的形容词经常在句中做表语或者定语修饰名词，也可以在句中构成形容词短语对主句的情况进行说明。过去分词转换的形容词常常用来修饰人或者与人有关的事物如look, appearance；现在分词转换的形容词常常用来修饰事物。
