读着读着，一女同学突然举手问道：Is tomato a fruit or a vegetable? 老师想了一下，答 ：那大家来举手表决一下！

      结果二十个学生一半对一半! 最后老师投蔬菜一边! 帯一学生提出可不可以用smart board 上网查？

      老师输入问题：what the difference between fruits and vegetables?

        大屏幕上答案显示出来： Seeds make the difference. Any fleshy part of a plant that grows from flower is called its " fruit. " If this part contains seeds, like an orange, an apple, a peach, or a tomato, it's considered a fruit. If it has no seeds, like broccoli or lettuce or carrots, it's a vegetable. 

       学生看完答案后，大叫Ms. B, you were wrong!

       那女教大笑，道：Ha, fifty percent kids did wrong with me!
