问题补充:
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。
