小题1:C
小题2:B
小题3:B
小题1:选C。由于作者并未打开钱包，更没有从中取出什么，所以说Nothing in the wallet was missing。
小题2:选B。根据文章最后一段中的Thinking about it later, I began wondering whether I would have been honest if I had known what was in the wallet! I thought that if I had no way to find the owner and no one returned to get it, I might keep it可排除选项C和D。比较选项A和B，再结合文章大意，选B为佳
小题3:选B。此题可用排除法来做：根据第1段最后两句He took out a twenty-dollar bill and handed it to me and I was amazed at this. “A reward for your honesty,” he said and then turned and walked away可知选项A与文章内容相符；选项B的意思是“作者直到失主返回来才将钱包还给他”，这显然与文章内容相符；根据第2段最后一句话The good feeling it gave me was worth more than anything could buy可知，选项D也与文章内容相符。
