It's afternoon so Helen has no class today.She got up early to go see her aunt and she is walking there now.As she was walking she came to a river.There was a board over the river,so Helen started to walk across.Suddenly,she fell into the river."Help!Help!"Helen cried.But nothing happened to her in the river,and she stood up.To her surprise,the water was not very deep.It only came up to her knees.
今天下午海伦没有课。她早早地起来去看望她的姑姑，她走着走着，走到了一条小河边，河面上架着一块木板。于是海伦开始过河，突然她不小心掉进河里，“救命啊！救命啊！”海伦哭着大叫，但谁也没有听到。于是她站了起来，令她惊讶的是，河水非常浅，仅仅到她的膝盖。
