那天,本来我是要继续上正课的,可是前一天晚上看到我班一位女同学的日记,我改变了主意。学校的小卖部离我们班的教室不是太远,平时同学们利用下课的两三分钟时间就可以买来饮料或零食,又飞快赶回教室里,还不耽误上课。今天上午,生物课马老师因做实验多用了几分钟,没能准时下课, On that day, I originally wanted to continue attending class. But the night before I saw the diary of a female classmate in my class, I changed my mind. The school’s canteen is not too far away from the classroom in our class. Usually, students can use the two or three minutes of the class to buy drinks or snacks, but also rush back to the classroom without delay. This morning, biology teacher Ma took more than a few minutes to do experiments and failed to leave classes on time.
