Question

 (2010年海南五校聯(lián)考)I have been living in Haikou for 10 years，but seldom________so lonely as now.

A．have I felt                                   B．I have felt

C．had I felt                                    D．I had felt

Answer 1

解析：選A�？疾闀r態(tài)和倒裝。分析but之后的分句，seldom，no，never等具有否定意義的詞置于句首時，句子要進(jìn)行部分倒裝，再結(jié)合前一分句的時態(tài)可知，答案為A。
