The river,you see,was never really safe at that time of the year-early autumn,I mean,when there is heavy rainfall.So when I heard the children had gone swimming as they used to all spring and summer,I knew there might be an awful accident.And when they came home late without litte Katie, I guessed what had happened.

你知道,这条河在每年的这个时候从来没有真正的安全过,我是说初秋,这时候雨量很大。所以，当我听说孩子们又象春天和夏天一样去游泳的时候，我想可能会发生事故。当他们很晚了才回家而且没带着Katie，我就猜到发生什么事了。
这是口语书里的吧？
