1. pay attention to the difference between "be able to" and "can/could"

be able to 的后面比较少用被动语态。be able to 是表示有能力作什么。其被动语态表示有能力被如何如何，不合理。排除A.

2.C/D: as. conj. 连词，后面接完整句子，所以 as people can.

C: computers can be programmed to think as people can (be programmed to think).

D: computers could be programmed to think like people.

把句子补完整后，再比较一下，C的句意就错了吧。
