网友回答
(答案→)accident / chance
解析：
【小题1】accident / chance 固定搭配by accident偶然，偶尔；
【小题2】 Wandering 本句中的动词wander与句子主语he之间构成主动关系，所以使用现在分词doing在句中作伴随状语。
【小题3】unbelievable 本句中的形容词unbelievable修饰前面的不定代词something，指一些令人难以相信的事情。
【小题4】when 本句中的连词when引导时间状语从句，修饰整个句子。
【小题5】contrary 固定搭配on the contrary恰恰相反。
【小题6】which / that 本句是一个定语从句，which/that指代先行词在句中作为动词open的宾语。
【小题7】 because 上下文串联。因为他衣着褴褛，使服务员对他很不礼貌。上下文之间是因果关系，故使用because.
【小题8】 whether / if 本句是一个宾语从句，因为前面有动词doubt说明怀疑的是不确定的事情。
