Question

【題目】—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。——我做完它之前已經工作了10個小時。

考查連詞。when當……時；after在……之后；since自從；before在……之前；根據句中I had worked for 10 hours.可知，我做完之前已經工作了10個小時，所以這里表達的是“在……之前”，故選D。
