Question

Not I but he________the same mistake again and again．

1. A.
   have made
2. B.
   has made
3. C.
   had made
4. D.
   make

Answer 1

B
分析：本题的主语是not I but he(不是我而是他)，用not A but B作为主语时，主谓语一致关系要看B的人称和数。(不能用had made，因为没有“过去的过去”概念)本题如果说成not he but I，句子就要改为Not he but I have made the same mistake again and again．(延伸)用A or B形式作为主语时，也是看后面的B．
