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.
