单选题
It happened in a flash, although ______ everything seemed to occur in slow motion, as though I were watching from another planet.
【正确答案】
D
【答案解析】[解析] 句子的大意为:当时事情很快发生了,不过现在回想起来一切好像发生得都很慢,如同我是在外星看一样。A项in return“作为回报,作为报答”;B项in practice“实际上,在实践中”;C项in reality“实际上,事实上”;D项in retrospect“回顾,一想起”。所以D项符合题意。
