Question

【题目】—Your DIY work is so wonderful.

—I had worked for 10 hours _________I finished making.

A.whenB.afterC.sinceD.before

Answer 1

【答案】D

【解析】

句意：——你的手工作品太美了。——我做完它之前已经工作了10个小时。

考查连词。when当……时；after在……之后；since自从；before在……之前；根据句中I had worked for 10 hours.可知，我做完之前已经工作了10个小时，所以这里表达的是“在……之前”，故选D。
