34. In the nineteenth century, Montreal grew into an important transportation and

A B

industrial center, aided by its many natural resources and an abundant of C D

hydroelectric power.

本人一看到B就选了，根本没看到D，比较才发现D确实错的绝对一些，请问大家做改错题的习惯，是不是全部看完选项才选？

B an important transportation and　industrial center　　

transportation and　industrial 做center的定语，应该按照平行原则词性相同呀

transportation 和industrial center是两个并列成分。transportation不做CENTER的定语

是的一定要看完。你可以看看BOBO关于做题目的方法。我有时也犯这么错误，希望我们吸取教训，共同进步！
