China sent up Shenzhou V manned spacship into space successfully,which shows science and technology___ rapidly in China.A.have been developing B.develops C.is developing D.has developed为什么不选A
A 改成has been developing就可以
science and technology 看成整体, 用单数谓语动词

这题的答案就应该选A啊
直接看science and technology是两个名词做主语,所以谓语动词要用复数形式啊
所以就直接排除了BCD啊,直接就选A啊
而A里的have been developing的时态也是正确的,表示一直到现在都在快速发展的
希望可以帮到你
