I feel very lucky to have an English teacher like Jane. Though she is strict in us, we all like her. Not only does she teach us a lot of knowledges about English, but she has very good sense of humor. One day, she tells us that day's homework was optional, that meant we were free to choose whether to do it or not. On the next day, she asked whomever had done the homework to raise hands. Seen a few hands were up, she said, “all right, let's to turn to the page and see what your homework is.” When we turned to that page, some faces turned red immediate. That was a blank sheet of paper. What a smart way to test my honesty.
