利用图片、图标、模型、幻灯片、电影电视等手段进行教学的直观类型是（）。

A．实物直观

B．模像直观

C．语言直观

D．抽象直观

答案

参考答案：B

解析：

实物直观指在感知实际事物的基础上提供感性材料的直观教学方式。例如，观察标本、演示实验等。模像直观指观察与教材相关的模型与图像(如图片、图表、幻灯、电影、录像、电视等)，形成感知表象。言语直观指在生动形象的言语作用下唤起学生头脑中的表象，以提供感性材料的直观方式。抽象直观是个迷惑选项。因此，本题描述的直观教学的基本形式是模像直观。

I was tired and hungry after a long day of work. When I walked into the living-room, my 12-year-old son looked up at me and said, “I 41 you.” I did not 42 what to say, and I just stood there, looking 43 at him. My first 44

  was that he    45  need help with his homework. Then I asked, “What was that all     46  ?”
“Nothing,” he said, “My teacher said we should tell our parents we love them and   47  what they say.”
The next day I called his teacher to    48   more about what my son said and how the other parents had reacted（反应） . “Most of the fathers had the    49   response as you did,” the teacher said, ”When I first         50    that we try this, I asked the children   51   they thought their parents    52   say. Some of them thought their parents would have heart trouble.”
Then the teacher   53  , “ I want my students to know that feeling love is an important part of    54  . I’m trying to tell them it’s too bad that we don’t express our feelings. A boy   55   tell his father or mother he loves him.” The teacher understands that sometimes it is   56   for some of us to say something that is good for us to say.
That evening when my son   57   to me, I took him in my arms and held on for an    58    moment, saying, “Hey, I love you,    59  .” I don’t know if saying that made    60   of us healthier, but it did feel pretty good.
