    My family was gathered for a barbecue when the discussion arose about a celebrity who earned a large amount of money. The major criteria for receiving millions of dollars seem to be determined by how much the audience will pay to watch the performer achieve.

    The discussion led to a sudden self-questioning. Why did I choose teaching for a career? I half-listened to their conversation as I pondered the answer.

    I remembered my three children watching me spend nights planning for my class. I remembered how they intently listened to my frustrations concerning materials, procedures and the amount of responsibility that seemed to endlessly be thrust into the laps of classroom teachers. I remembered when it came time for each of my own children to choose a profession. How I waited to hear if any had plans to follow Mom into teaching. Long considerations held no mention of anyone becoming a teacher.

    Dessert was being served, and everyone was still involved in the discussion of the enormous salary of one individual, when the phone rang. My husband handed the phone to me.

    “Hello, this is Bonnie Block,” I said.

    “Is this the Bonnie Block who used to teach kindergarten?”

    A nervous sensation swelled in me, and my mind raced with memories of those days long ago.

    “Yes!” I exclaimed with a lump in my throat. It seemed like forever as I waited anxiously to hear what the caller would say next.

    “I am Danielle—Danielle Russ. I was in your kindergarten class.”

    Tears of surprise and joy rolled down my flushed cheeks.

    “Yes,” I uttered softly as I remembered that darling, wonderful child.

    “Well, I am graduating from high school this year, and I have been trying to find you. I wanted you to know what a difference you made in my life.”

    She proceeded to give details. My influence on her wasn’t limited to kindergarten but remained a strong motivating force when she needed a coach to help her meet a challenge. “I pictured you praising and encouraging me all the way.”

    Why choose teaching?

    The pay is great!

小明同学在探究“动物的绕道取食”时做了这样的实验:他把章鱼(软体动物)放到大鱼缸中,中间放一块玻璃板,将鱼缸隔成两部分,玻璃板高度低于玻璃缸的高度,使章鱼能从玻璃缸的一侧越过玻璃板游向另一侧,同时将食物(小虾)放入玻璃板的另一端,当章鱼看见食物时,只是扑向玻璃板,在玻璃板上乱撞,不会绕过玻璃板去捕捉。多次碰撞之后,才能学会绕道;而另一组同学在用小狗做实验时,只用一次小狗就学会了绕道捕获食物。请分析回答下列问题:
  1. (1) 在上述实验中,章鱼、小狗越过障碍物而获得食物,都属于行为。这是动物在成长过程中,通过学习和逐渐建立起来的行为活动。
  2. (2) 上述实验证明,某些低等动物也可以形成行为;动物越高等,学习能力越,能利用经验来解决生活中的问题,这大大增强了的能力.
