简谐运动的振动图线可用下述方法画出：如图(1)所示，在弹簧振子的小球上安装一枝绘图笔P，让一条纸带在与小球振动方向垂直的方向上匀速运动，笔P在纸带上画出的就是小球的振动图象．取振子水平向右的方向为振子离开平衡位置的位移正方向，纸带运动的距离代表时间，得到的振动图线如图(2)所示．

①刚开始计时时，振子处在     位置（填左边最大位移处或右边最大位移处），t＝17 s时振子相对平衡位置的位移是      cm，此时速度为        （填正或负）向最大。

②若纸带运动的速度为2 cm/s，振动图线上1、3两点间的距离是       cm。

     This is a true story about something that happened between a customer of General Motors and its Customer-
Care Executive (客服主管). The following complaint was received by General Motors "...It may sound crazy,
but it's a fact that every time I buy a   1   ice cream, and come back from the store, my car won't start. If I get
any other kind of ice cream, the car starts   2   fine. Why?" The executive was   3   about the letter, but sent an
engineer to check it out anyway.
     The   4   made three visits to the store with the customer. The first time, he got chocolate ice cream. The car
started. The second time, he ordered strawberry. The car started. The third time he got vanilla. The car failed to
start. The engineer   5   to believe that the man's car was allergic (过敏的) to vanilla ice cream. He   6   his visits,
and noted all sorts of data: the types of gas used and the time it took to drive back and forth.
     Soon he came a clue: it took the man less   7   to buy vanilla than any other flavor (味道). Why? The answer
was in the layout (布局) of the store. Vanilla, as the most   8   flavor, was in the front of the store for quick
pickup. All the other flavors were kept further back, where it took longer to buy them.
     Time was now the   9   not the vanilla ice cream! The engineer quickly put forward an answer:"engine
trouble." The extra time taken to get any other flavor 10  the engine to cool down longer. When the man got
vanilla, the engine was still too hot to start.
     Even crazy-looking problems can be real. What really  11  is your attitude to the problem.
     Don't just say something is "IMPOSSIBLE" without putting a sincere effort into  12  it out. If you look closer,
you may discover that it's possible after all.
