3 （本题12分）要求摩托车由静止开始在尽量短的时间内走完一段直道，然后驶入一段半圆形的弯道但在弯道上行驶时车速不能太快，以免因离心作用而偏出车道。求摩托车在直道上行驶所用的最短时间。有关数据见表格。某同学是这样解的：要使摩托车所用时间最短，应先由静止加速到最大速度 v 1＝40 m/s，然后再减速到v 2＝20 m/s， t 1 = = …； t 2 = = …； t = t 1 + t 2 你认为这位同学的解法是否合理？若合理，请完成计算；若不合理，请说明理由，并用你自己的方法算出正确结果。

6 完形填空。 What I noticed first about my new parrot, Chico, was that he couldn"t fly. His wings had been cut short and he was stuck on the 1 just like us humans. When the weather turned nice, I took Chico outside. I sat him on a branch of a tree, hoping to make him 2 . At first he seemed 3 . He walked back and forth on the branch looking anxious or nervous. He didn"t even flap his wings in an attempt to fly. Somehow he knew he was 4 . One day Chico got especially excited . He paced back and forth and made an incredible amount of 5 . Then all of a sudden he stopped and let out an even louder scream. He started 6 flapping his wings for the first time ever－then he lifted off the 7 like a space shuttle! I was amazed and 8 . Little did I know his feathers had been growing back, and Chico had been 9 until the moment was ripe for escape! Two days later Chico 10 .

From that day on, whenever the weather was good I would let him out early and he would fly around and be back before dark. The 14 lasted for two months before suddenly Chico became 15 . The vet said that he had been infected with a disease from the pigeons in the neighborhood. Within a few days he died. I was very sad. The 16 crossed my mind that if I had not set him free to fly, he would be still alive. But what 17 is there in being a bird if you can"t fly?
