问题补充:
A new museum is being built in our city and it’ll be accessible to the citizens when next year.
A. completing
B. is completed
C. to be completed
D. completed
答案:
A. completing
B. is completed
C. to be completed
(答案→)D. completed
解析:考查非谓语动词。it指代的是the new museum,也是complete的逻辑主语,且是被动关系,故应用过去分词表被动。When completed=When it is completed.
