第33题:[单选题]The residents, ___________had been damaged by the flood, were given help by the Red Cross. A.all their homes B.all whose homes C.all of whose homes D.all of their homes 参考答案:C 考查非限制性定语从句。句意为“那些房屋全部被洪水毁坏的居民得到了红十字会的救济”。两个逗号之间显然是一个非限制性定语从句,所以用关系代词whose指代the residents。因为whose后面接的是一个从句.所以要用代词all of而不用形容词all。正确答案为C。
