 (2010年海南五校联考)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：选A。考查时态和倒装。分析but之后的分句，seldom，no，never等具有否定意义的词置于句首时，句子要进行部分倒装，再结合前一分句的时态可知，答案为A。
