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

試題分析：考查狀語(yǔ)從句的省略式：句意：英語(yǔ)說得不好的工人在和外國(guó)顧客互動(dòng)的時(shí)候，可能有劣勢(shì)，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(yǔ)一致的時(shí)候，可以省略主語(yǔ)和be動(dòng)詞，選A。
點(diǎn)評(píng)：當(dāng)狀語(yǔ)從句的主語(yǔ)與主句的主語(yǔ)一致，且狀語(yǔ)從句中有系動(dòng)詞be的時(shí)候，可以把狀語(yǔ)從句的主語(yǔ)和be動(dòng)詞一起省略。如果狀語(yǔ)從句中有it is的時(shí)候，it is 也可以省略。
