Question

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

Answer 1

D

    
試題分析:考查動詞時態(tài)。固定短語in the past years“在過去的幾年里”是現(xiàn)在完成時的標志，排除A、C選項，而由語境可以判斷new things 和discover是被動關系，應該用被動語態(tài)，所以D選項正確。句意：隨著高科技的發(fā)展，在過去幾年里越來越多的新事物被發(fā)現(xiàn)了。
