Question

【题目】_______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：尽管他们很累，他们还是一直工作到半夜。

考查连词。Although尽管；but但是；so所以；Although和but不能连用；分析句子“_______they were so tired，______they kept on working until midnight” 他们很累，他们还是一直工作到半夜，所以此处是转折，故选B。
