阅读下面材料,回答问题。
我就英语《Cock&Clock》这篇材料进行了认真备课。对上好这节课充满了信心。当我给学生板书单词cock(公鸡)时,一个意想不到的事情发生了。班上一个男孩子突然站了起来,恶作剧似的怪声怪气问我道:“老师,没有母鸡呀?”全班立刻哄堂大笑……我当时窘迫极了。作为一个新老师,我从来遇到这种情况,真想找个地缝儿钻进去。生气归生气,但我并未表现出来,经过短暂思考,我有了主意。我沉静地看着这个学生,继续对全班学生清晰地说:“同学们,在英语里,有cock(公鸡),也有hen(母鸡),chicken(小鸡)。”说着,将母鸡、小鸡的单词板书下来。这种做法,学生们感到意外,但他们很安静。我接着说道:“这位提问的同学能发现问题,并敢于提出来,值得表扬,但同时还要批评你,一是发言不举手,二是说话怪声怪气。同学们,你们知道说话的语气对表达语义的作用吗?”我又给学生们举出了几个因语气不同可能表达不同词义的词语实例。接下来的讲课非常顺利,学生们屏神静气地听讲,连那顽皮的男孩子也安静地坐着,不好意思地看着我仿佛是在向我道歉……
问题:材料中的“我”贯彻了哪些教学原则?试加以分析。

语言素材:
Who invented tea?
Did you know that tea, the most popular drink in the world(after water), was invented by accident? Although tea wasn't brought to the western world until 1610, this beverage was discovered over three thousand years before that. According to an ancient Chinese legend, the emperor Shen Nong discovered tea when he was boiling drinking water over an open fire. Some leaves from a nearby bush fell into the water and remained there for some time. The emperor noticed that the leaves in the water produced a pleasant smell. Later he decided to taste the hot mixture. It was quite delicious. And in this way, one of the world's favorite drinks was invented.
