    With the development of high technology, more and more new things ______ in the past years.
    A．discoveredB．have discovered
    C．had been discoveredD．have been discovered
    D
        
    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。
