英语选择题Itwasnotuntilthetwentiethce

英语选择题Itwasnotuntilthetwentiethce: It was not until the twentieth century that modern poetry__________. A was been relly eloping B was really developed c has relly developed 请解释一下题目的意思和各个选项的意思,为什么C的对的?; 楼上的有一个知识点没有弄清楚，物体develop可以被动也可以主动的。比如中国正在发展，China is developing，你难道不觉得说China is being developed很别扭吗？这个词我也问过老师，老师就是这么回答的。所以C是正确的，如果说has been really developed也是对的。
