思路：with on 改成 without,语气发生变化：干掉 D,E; there be 是一个有效性的错误； 干掉 C； A和B中,A 的estimate 是动词词性,B的是接在所有格后面,故推断为名词词性；干掉.选A.可是错了.为什么?

50题,我认为estimate不能用A这种结构, 即estimate sth to do, 应该是estimate that .结构,其中that可以省略. 所以只有C符合.(PS: C选项你确定你没有打字错误?)
52题,选B的原因不是因为would就一定表示“虚拟”或“过去时", 我感觉这里的语气不是很强,所以用would control,而A则太肯定了.
