If Newton lived today,he would be surprise by what ___ in science and technIfNewton lived today,he would be surprise by what ____ in science andtechnology.A.had discovered B.had been discoveredC.has discovered D.has been discovered选哪个,用什么
选D,如果牛顿还活着,他会对现如今科学和技术上的发现感到惊讶.what指代的是science and technology,作主语是用单数,并且说的是现如今,所以选has,discover的主语是物是用被动,被发现,所以选D不选C,不懂了还可以问我,希望能帮到你
B。 科学技术是已经被发现,所以只能是B D 完成被动,尤其是宾语从句前面是过去时后面只能过去完成时,就是B
