A.have…interrupted
B.had…interrupted
C.are…interrupting
D.were…interrupting

在这题中强调一直打断,所以要用进行时。

28.More and more people realize we won’t have clean water to drink unless something _______ soon.
A.was done
B.will be done
C.to be done
D.is done
选D。unless引导的条件状语从句,主将从现,主句用将来时,从句用一般现在时,因为是被动,something是单数所以用is done

32.New York is truly an exciting place and we’ve decided to stay for _______ three weeks.
A.another
B.other
C.the other
D.other’s
选A。another three weeks意思是在多呆三周,也可以表达为three weeks more.
