68. The Mississippi riverboat, which evolved fromsimpler steamship of the early 1800's, became

       the dominant form of passenger transport on the Mississippi River.

      

       我选A个人认为riverboat evolved应为被动 riverboat was evolved.

35. The outstanding feature of copper and the other

   metals of Group IB in the Periodic Table is _________

   chemical attack.

                 resists  

                 to resisting  

                 their resistance to  

                 by resistance  

是不是be动词后只能跟noun and adjective?偶选B。觉得也说得通。

答案是Ａ吗，偶认为这里不用被动要好点，也是能说的过去呀，evolve是指他的发展，主动也可以的，到是Ｄ的单复数有些疑惑．
