1. 关于主被动。一个城市应该是“被改造”而不是城市自己改造自己。再啰嗦一下肯定是市民啊、领导啊神马地改造了这个城市，所以如果是LA做主语的话，肯定是用被动。LA was transformed. 毕竟LA又不是transformer~


2.关于时态的问题。在本题中。既没有since之类的完成时的明显标志词，也没有强调过去一个动作对于现在的影响。只是简单描述事实。所以没有理由用完成时。过去时就足够了。


3.关于对from 1973 to 1993的修饰。 ABC选项都是使用同位语，an era in which。。。DE显然都是想使用定语从句。但是这里就涉及一个在修饰时间时，到底是“介词+ which” 还是使用when的问题（类似的问题包括where and "介词+which"）。个人觉得，如果是明确的时间段，如1973-1993，或类似的纯时间表达，就用when。如果是period, era, festivals, vacations这类词都是“介词+when”的形式，如in which era, during which period.（耐心的筒子可以再去查查语法书）


所以，DE应该用when。A的when和had done都有问题。C的逻辑有问题，不是时代改造城市，而应该是人。


大概就是这样，一家之言咯~仅供参考哈~

应该是因为DE中的which无从指代吧？

选E没指代的吧，还是选B比较通。
