With the development of high technology, more and more new things in the past years.

A. discovered

B. have discovered

C. had been discovered

D. have been discovered

答案：

A. discovered

B. have discovered

C. had been discovered

(答案→)D. have been discovered

解析：

试题分析:考查动词时态。固定短语in the past years“在过去的几年里”是现在完成时的标志，排除A、C选项，而由语境可以判断new things 和discover是被动关系，应该用被动语态，所以D选项正确。句意：随着高科技的发展，在过去几年里越来越多的新事物被发现了。
