假设今天是2006年11月20日，星期一。在你上学的途中，突然不远处传来呼救声。你跑过去，发现一个小男孩在水中挣扎。你放下书包，衣服来不及脱就跳进河里去救他。河水发冷，你冷得发抖，但仍然继续往前游，最后把他拉上岸。这时孩子的母亲赶到了，她非常感激你，说：“要不是你及时赶到，我儿子也许已经淹死了。”并问你叫什么名字，你笑了笑说：“我是共青团员。”
根据以上提示，用英语写一篇日记。
内容提示：
1)背景描述：上学途中
2)故事发生：看见小男孩在水中挣扎
3)故事高潮：救人过程
4)故事结局：小孩被救，母亲感谢
写作指导
1)注意日记的格式。在第一行写清日期和星期及天气情况。
2)按照时间顺序来写。
3)使用恰当的连接词。
疑难注释：
1)struggle in the river：在河里挣扎
2)“Without you my son might have drowned”：如果没有你我儿子可能淹死了。该句用了虚拟语气，表明与事实相反的假设。
as if和as though引导的从句所叙述的情况与事实相反时，从句的谓语动词多用虚拟语气。在虚拟语气结构中，用________时态来表示现在的情形；用________时来表示过去的动作或状态；用________时表示正在进行的动作；用________时表示将要发生的动作。
当as if和as though从句的主语和主句主语一致，且从句中含有系动词be的某种形式时该主语和系动词可以省略。
例如：John paused as if(he was)expecting Mary to speak．
