Workers who cannot speak good English may be at disadvantage ____ with foreign
customers.

A．when interacting	B．when interacted
C．when to interact	D．when being interacted

答案

A

解析

试题分析：考查状语从句的省略式：句意：英语说得不好的工人在和外国顾客互动的时候，可能有劣势，是省略句，完整的句子是：Workers who cannot speak good English may be at disadvantage they are interacting  with foreign customers. 当主从句的主语一致的时候，可以省略主语和be动词，选A。
点评：当状语从句的主语与主句的主语一致，且状语从句中有系动词be的时候，可以把状语从句的主语和be动词一起省略。如果状语从句中有it is的时候，it is 也可以省略。
