english choice our civilization cannot be thought of as ()in a short period of time. a.to have been created b.to be creased c.having been created.d being created
D being created是对的, 补全了应该是as it is being created in a short period of time. 我们的文明不能被认为是短时间建立起来的. 后面应该是一个完整的句子,但是存在省略问题, 在省略的时候,形式主语it和be动词都要省掉,所以直接是being 其实还蛮简单的叻
