Question

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

Answer 1

A

解析試題分析：考查狀語從句的省略式：句意：英語說得不好的工人在和外國顧客互動的時候，可能有劣勢，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. 當(dāng)主從句的主語一致的時候，可以省略主語和be動詞，選A。
考點：考查狀語從句的省略
點評：當(dāng)狀語從句的主語與主句的主語一致，且狀語從句中有系動詞be的時候，可以把狀語從句的主語和be動詞一起省略。如果狀語從句中有it is的時候，it is 也可以省略。
