单选题 It was one of those days when it looked at first something interesting could happen, but then later, when you didn't expect anything, almost everything happened.

【正确答案】 A
【答案解析】[解析] 根据上下文的语境，可推断出本句意为：就在那些日子里，开始看似不会有什么有趣的事发生，但后来当你并不期待任何事会发生时，却几乎每种事情都发生了。[因为前面需填之词应与后面所提的：not…anything语义一致]；因此答案为A。
