I____a novel written by O.Henry,a well-known American short story writer last night,and I'll finish it another night.
A.read,B.have read,C.had read.D.was reading.
答案:A
read也是过去式

时间状语last night 说明只能用过去式，read 选a

I____a novel written by O.Henry,a well-known American short story writer last night,and I'll finish it another night.
A.read,B.have read,C.had read.D.was reading.
自己知道BC不能选.请详细解答选择的理由.
答D.
简化：I was reading a novel last night and I'll finish it another night.
分析：BC你说了不能选,省得我讲如何排除了.A表示已经完成,D.只表示昨天晚上在看书,不表法完成.从后句看,选D最佳.
评题:O.Henry是名作家,不需要这么长一个同位语.不能为了增加干扰而将这个重要的时间状语last night脱离它应站的岗位!即使象我这样简化,除了容易排除BC外,选A的人还是会有不少的.因为last night是过去时间嘛,用一般过去时,很常见,很正常啊!（看楼上四个答案可知）
但楼上不知道出题者考什么.
考一般过去时和过去进行时的区别：
区别一：过去进行时强调动作在过去某时刻正在进行或持续,而一般过去时表示动作的完成.如：
He was writing his composition last night.他昨晚在写作文.(不一定写完)
He wrote his composition last night.他昨晚写了一篇作文.(已经写完)

bc都是完成时，不能用
选择a 是过去时
