一那一年我15岁,虽然时间已经过了很久,但那个夏天的一件事至今让我无法忘记。那是一天下午放学后的时间,教室里只有我一个人在做值日。别人做值日总是两个人或者三个人,而我却总是一个人,这样的情况已经持续很久了。虽然一个人打扫卫生很辛苦也很孤独,但我却很喜欢这种情况。 I was 15 years old that year. Although the time was long past, one thing that summer has so far I cannot forget. That was the time after school one afternoon, and I was alone in the classroom. There are always two or three people on the day, and I am always alone. This situation has been going on for a long time. Although one person is very hard and lonely when cleaning, I like it very much.
