  • 第1题：

    Which of the following statements about teachers' instructions is NOT true?

    A．Instructions should be simple and clear.
    B．Instructions can be long and complicated for students to follow.
    C．Teachers can use body language to assist students to understand.
    D．Instructions should be kept to a minimum during activities.

    答案：B
    解析：
    考查课堂教学中的教师指令语。教师的课堂指令语应简洁明了，这样学生才会明白；切忌长而复杂．这样不便于学生理解，也会影响教学的效率。教师在课堂上应尽量少用母语，必要时可以使用身体语言辅助学生理解。课堂指令语不应过多，教师应最大限度地发挥学生的主观能动性。故选B。
