某学生为了探究影响化学反应速率的外界因素，进行以下实验。 （1） 向100mL稀硫酸中加入过量的锌粉，标准状况下测得数据累计值如下： 时间/min 1 2 3 4 5 氢气体积/mL 50 120 232 290 310 ①在0~1、1~2、 2~3、3-4、4~-5min各时间段中：反应速率最大的时间段是 min，主要的原因可能是。反应速率最小的时间段是 min，主要的原因可能是。②为了减缓反应速率但不减少产生氢气的量，可以在稀硫酸中加入（填序号Some people believe that dreams can tell them what will happen in the future. Nobody knows why this is so, but there are many stories about people. The people make their dreams 1 . One of these people was a man called John Chapman, who lived in Swaffham in England many years ago. John Chapman dreamt that he stood on London Bridge and a man told him how to become rich.
