1. A.
   are being developed
2. B.
   have developed
3. C.
   developed
4. D.
   will develop

Answer 1

A
试题分析：考查主谓一致和时态，时间是now，computers和develop是被动关系，用现在进行时的被动，主语是The new generation of computers, with artificial intelligence,中心词是computers，所以谓语是复数，句意：有着人工智能的新一代电脑正在被开发完善。选A。
考点：考查主谓一致和时态
点评：主谓一致的题目先要找到关键的主语，当主语比较多的时候要找到中心词，看主语是单数还是复数，时态填要注意关键的时间状语。
