问题补充：

All the apartments have been sold out while the building is still .

A. Constructed

B. constructing

C. under construction

D. in construction

答案：

A. Constructed

B. constructing

(答案→)C. under construction

D. in construction

解析：考查construct的相关短语和用法。under construction在建设中 A选项没有体现正在进行，只体现了被动；B项只体现了现在进行时，但没有被动含义，故错误。表示“正在建设”我们多用under construction.故选C.
