1.
两个完全相同的条形磁铁，放在平板AB上，磁铁的N、S极如图所示，开始时平板及磁铁皆处于水平位置，且静止不动．
⑴现将AB突然竖直向上平移（平板与磁铁之间始终接触），并使之停在A″B″处，结果发现两个条形磁铁吸在了一起．
⑵如果将AB从原来位置突然竖直向下平移（平板与磁铁之间始终接触），并使之停在位置A′B′处，结果发现两条形磁铁也吸在了一起，
则下列说法正确的是（ ）
2.如图，已知菱形ABCD的顶点A（﹣ {#mathml#}{#/mathml#} ，0），∠DAB=60°，若动点P从点A出发，沿A→B→C→D→A→B→…的路径，在菱形的边上以每秒0.5个单位长度的速度移动，则第2017秒时，点P的坐标为（ ）
3.如图，点A在双曲线y= {#mathml#}{#/mathml#} 上，点B在双曲线y= {#mathml#}{#/mathml#} （k≠0）上，AB∥x轴，分别过点A、B向x轴作垂线，垂足分别为D、C，若矩形ABCD的面积是9，则k的值为（ ）
8.如图，在圆心角为90°的扇形AOB中，半径OA=3，OC=AC，OD= {#mathml#}{#/mathml#} BD，F是弧AB的中点．将△OCD沿CD折叠，点O落在点E处，则图中阴影部分的面积为{#blank#}1{#/blank#}．
