Question

—Lingling, do you know ________________?

—It’s reported that it will be finished in 2025.

A.how Subway Line 7 will be finished B.how will Subway Line 7 be finished

C.when Subway Line 7 will be finished D.when will Subway Line 7 be finished

Answer

C

【解析】

句意：——玲玲，你知道地铁7号线什么时候完工吗？——据报道，它将在2025年完成。

考查宾语从句。how Subway Line 7 will be finished陈述语序，地铁7号线将如何被完成；how will Subway Line 7 be finished疑问语序，地铁7号线将如何被完成；when Subway Line 7 will be finished陈述语序，地铁7号线将何时被完成；when will Subway Line 7 be finished疑问语序，地铁7号线将何时被完成。you是主语，know是谓语，句中缺少宾语，可以用宾语从句充当宾语，宾语从句要用陈述语序，排除B和D选项；根据答语“It’s reported that it will be finished in 2025.”可知，此处询问时间，用when引导宾语从句。故选C。
