Jack was a strong boy and could complete any task in physics class. One day I asked the kids to integrate art and physics into a 1 using pulleys(滑轮). They should solve a problem of their own design, drawing it on paper, yet with absolutely physical 2. "Mr. Lampert," Jack said, "I can't 3." I was very 4 with his reaction but assured him he could do the 5.
The day the assignment was due, Jack invited me to his barn(谷仓). As we 6, I saw a whiteboard with Jack's simple drawings of pulleys, ropes and various mathematical calculations. We walked further and I was 7 to see what Jack had been working on. 8 from a high girder(大梁) was a strong rope winding through several pulleys; at the end was a platform 9 with at least four hundred pounds of hay(干草) and old tractor parts. Jack said to me, "Mr. Lampert, jump on!" He explained to me how he had 10 the exact lifting force needed and then Jack smiled as he pulled the entire weight and me up and down 11. "What do you say? Is that an A?" he asked. "Jack, that's an A-plus!" I said 12 as he let me down.
While I had 13 whether Jack would solve his shortcomings, Jack had clearly stepped up to the challenge. He created a masterpiece and 14 that students can and will solve pretty much anything you present them. Jack was strong physically, but more importantly, he was 15.
