白板70 x 50。本练习总共设计了以下三种类型的主题。1.？?猜一猜? ?:让学生用??钢丝刷? ?在吗? ?画刷? ?猜答案，读单词的发音。这个小话题极大地调动了学生们的读写热情。每个人都渴望起床，提高自己的读写能力。 Second, "discriminate and distinguish", this is a small exercise that students use the whiteboard pen to connect the group words to distinguish the near-words and select the words to fill in the corresponding sentences. The students recognize the new words in the process of identification and selection. Understand the meaning of the word. The third is to connect words into sentences. In the operation of dragging the word module, by the way, the partial and second characters appearing in this lesson are memorized. If these three small questions are copied on the blackboard in a traditional way, or demonstrated on a projection, the trouble of the process and the waste of time are conceivable. Because of the electronic whiteboard, the training process is intuitive and flexible, and a comprehensive training problem is easily accomplished with remarkable results.
