Question

---Peter hasn’t been abroad before.He knows little about foreign culture.
---________.
A.So have I.B.So do I.C.Neither have I.D.Neither do I.
所给答案是C,为什么不是D呢?还是两者都行呢?到底否定的是哪一句呢?

Answer 1

时态要一致,原句是现在完成时（has been),后一句也要是现在完成时.所以用了现在完成时的那个助动词have.
Neither have I 是Neither have I been abroad before的省略.
