(答案→)suddenly
解析：短文属于说明文。短文分析了“害怕被嘲笑”的恐怕心理，到底是因为普通的羞涩还是真的害怕被嘲笑，研究人员在做调查研究。
【小题1】意思是：在说话时，突然开始大笑。此处需要一个副词。
【小题2】“可笑的事”，形容词后置，修饰不定代词something。
【小题3】用于a 和名词之间，使用形容词；mon“普通的，平常的”。
【小题4】the same“一样的”，与后句的“differs from…”相对应。
【小题5】feel sure of oneself “有自信”，这里使用了sure的否定形式；主语是Shy people，因此使用they的反身代词themselves。
【小题6】根据“they had been laughed at”可知用了过去完成时，是比说话时更早的事情，用before泛指以前。
【小题7】情态动词can后，使用动词原形。
【小题8】根据上下文可知这里指研究人员，用复数形式。
【小题9】通过上一句“the difference between normal shyness and true fear of being laughed at.”可知，目的就是为了做比较。此处用动词不定式短语做表语。
【小题10】这里指调查、研究的结果，用复数形式。
