He knows nothing besides study. When I see him, he will be holding a book in his hand and he is not interested in any activity, so I don't think it is a good idea to elect him monitor in our class. In my opinion, a leader in class should be an all-round one." After hearing this, I stood up and said to that guy, "my dear fellow, don't tell tales out of school. This is Andy here and I have heard what you said." 一次吃早餐的时候，Andy偶然听见有人在背后谈论他，说他是个书呆子，He is a nerd. 说什么也不会选他当班长。接下来他们又提出一个理由就是班长应该是一个全面的、综合素质比较强的学生干部。其实这些说法都是对的。可是在Andy看来可是很难容忍的，竟然在背后说我的坏话，于是Andy站起来警告他们不要背后论人是非！Don't tell tales out of school！ 1） He is a nerd！他是个书呆子！
2） Don't tell tales out of school. 不要背后论人是非长短！ 「请你猜猜看」挑战自我，情景抢答也刺激！ Here are three situations: S1. Mr. Smith has a lot of books in his family and he will be reading them as long as he is at home. Besides, he also likes listening to the music, dancing, having sports. Do you think Mr. Smith is a nerd? S2. When you hear someone talk about your bad habits and shortcomings, you, of course, will be angry! Do you think you will be brave enough to critize them? If so, what would you say to them? S3. Can you give me a definition of the word "Nerd"?
