28.请认真阅读下列材料，并按要求作答。请根据上述材料完成下

参考解析（1）首先，要注意控制音量和语调，不要一直用一种声调进行授课。在讲授重点知识时声音要适当放大，以使学生感知到这一部分知识是重点。从而集中注意力。其次，可以在学生疲倦的时候安排游戏环节。学生由于年龄小，对游戏都比较感兴趣，所以设置适当的游戏会吸引学生的注意力，调动学生参与课堂的积极性。最后，如果教师在课堂上发现某名同学注意力不集中，可以适当地让该名学生回答问题，学生起立回答完问题之后注意力也会有很大提升。总之，教师在教学的过程当中要时刻注意观察学生的注意力和课堂参与度，调动学生的积极性，引导他们认真学习知识。（2）Knowledge aim: Students can understand the meaning of the words: living room, bedroom, study, kitchen,bathroom.
