太感谢楼主了。但是我十分不才,外加大脑有点混乱。。。有地方看不懂 1、第二段那里: “one may trace this trend/problem back to but it doesn’t answer the question of/why…解决这些问题的方法…” trace bake to 什么?but之前应该写什么呢? 2、this alone does not provide sufficient support to convince us, it is too weak to strengthen the point that 反对面 is of greater benefits for us. So I firmly convinced that… 是反对面吗?还是应该是我支持的观点那一面啊?
