请教大家一道语法题

35. Dams are used to control flooding, provide water for irrigation, and generating
                

                      A                                  B              C

electricity for the surrounding area.

                                  D

答案选C。我选A，应该是be used to doing 才对呀！为什么呢？

C是错的.那个generation要用动词,和前面的provide 一致. be used to do应该是可以的.

cyf3732

be used to doing sth. 的意思是“过去习惯于做某事“，而这里的意思是“被用于做某事”。题设A是一个小小的陷阱。
