a．are being built　　　
b．were being built
c．was being built　　　
d．is being built
解析：　句意为：据报道，目前在这个受灾地区正在建很多新房子。本题考查的是主谓一致和时态。many a：a large number of 许多。many a 单数名词 单数动词。如：many a strong man has weakened before such a challenge.很多坚强的人面对这种挑战都动摇了。many a famous pop star has been ruined by drugs.很多著名的流行音乐歌星都因毒品而被毁了。根据谓语动词应该用单数，排除a和b两项。根据at present，时态应该是现在时态，所以d选项是正确的。

答案：　c
4．(XX•4月济南模拟)—flight mu257________.i must be off now.
—have a nice trip.
a．is being announced　　　 b．has announced
c．was announcing　　　  d．had been announced
解析：　考查动词的时态和语态。从语境知“mu257航班正在通知(登机中)”，此处强调“现在这个时刻正在进行”的动作，所以用现在进行时，同时announce与flight mu257又是动宾关系，故用“现在进行时的被动语态”。
答案：　a

—oh，i forgot to tell you.the new machines in the nearby plant________.
a．were tested　　　 b．will be tested

答案：　c
