Question

【題目】_______they were so tired，______they kept on working until midnight.

A.Although: butB.Although: /C./: so

Answer 1

【答案】B

【解析】

句意：盡管他們很累，他們還是一直工作到半夜。

考查連詞。Although盡管；but但是；so所以；Although和but不能連用；分析句子“_______they were so tired，______they kept on working until midnight” 他們很累，他們還是一直工作到半夜，所以此處是轉(zhuǎn)折，故選B。
