以下是引用tulongqishi在2006-3-9 22:59:00的发言:38. Animals have to cope with and control physical and chemical processes that do not necessarily act to benefit of the animal. A B C D
答案选d 我觉得c的 that 应该改成those. 15. A challenging new area in inorganic chemistry is ---- the role of transition metals in the biochemical catalysts called enzymes. (A) that of understanding (B) to have understanding (C) the understanding (D) understanding that 答案选A 不明白为什么,请各位大侠帮忙讲解一下。
1. 个人觉得B没错, that做定语. D,是act to do , 我觉得应改用act as
2. A是对的, that 指前面的area.其它几个意思不对. |
