Question

The room, although_________ to be kept locked, was often left open.

A．supposing

B．supposed

C．to be supposed

D．having supposed

Answer 1

B

試題分析：考查狀語(yǔ)從句的省略：句意：這個(gè)房間雖然應(yīng)該一直鎖著，但總是開(kāi)著。完整的句子是：The room, although it is supposed to be kept locked, was often left open.當(dāng)主從句的主語(yǔ)一致的時(shí)候，可以省略從句的主語(yǔ)和be動(dòng)詞，選B。
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。
