问题补充：

It is reported that many a new house at present in the disaster.

A. are being built

B. were being built

C. was being built

D. is being built

答案：

A. are being built

B. were being built

C. was being built

(答案→)D. is being built

解析：many a +名词的单数形式，谓语动词使用单数，故排除ＡＢ，又从时间状语 at present可得知与现在有关，故选择答案Ｄ。句意：据报道，目前许多新房子在灾难中正被盖起来。
