what about the sick old man in that cart②? is he well now? every time i think of what happened to me a year ago, i feel i was to blame③.

　　it was a saturday evening, the third evening after my arrival at zheng ding middle school. i was a new comer and knew little about the town. after supper, i went out for a walk alone. it was getting dark and few people were in the street. suddenly a cart stopped and the man who pulled the cart came to ask me if i knew the way to the no. 1 hospital.　i had heard of the hospital and i seemed to have been told that it was in the north of the town, but i was not quite sure. i looked at the sick old man lying in the cart and moaning④. without hesitation, i told him the way to the hospital. then he turned the cart round and soon it was out of sight. when i came back to the dormitory, i told my roommates what had happened. they told me that the no. 1 hospital was in the southeast of the town. only then did i realize that i had told the man the wrong way. i at once thought of the sick old man and felt upset⑤.

　　what would they do if they couldn't find the hospital? would the sick old man survive⑥the journey? i couldn't think any more. i was too upset.

　　a year has passed. i am still worrying about the old man. maybe i will never have a chance to make it up, but from then on i have never said a word that i am not sure of.
