在我家附近的大道上，有一块低洼的地面，每当大雨过后，人们很难通过。一天，大雨刚停，我和几个调皮的小孩聚集在低洼地周围，观察行人是如何通过的。这时，走来一个老人，他无法通过那块低洼地，又不知该怎么做。我们却站在一边看笑话，没有人想去帮助他。过了一会儿，有两个少先队员走过来，把老大爷搀扶过了水坑。看见这一幕，我们都羞红了脸。

There is a piece of low-lying land in the street near my home。 It is hard to pass after a heavy rain。 One day just after a rain， several naughty kids and I gathered around and watched how people passed by。 Then there came an old man。 He couldn"t pass and neither did he know what to do。 We just stood there laughing。 After a while， two members of the Young Pioneer came over and gave the old man a hand。 On seeing that， we all blushed with shame。
