如图所示为甲、乙两质点的速度-时间图象，下列说法中正确的是（ ）
A．甲做直线运动，乙做曲线运动
B．甲做的是匀速运动，乙做的是加速度增大的加速运动
C．在0到t0时间内甲的位移等于乙的位移
D．在t0时刻甲、乙相遇，相遇前甲的速度大于乙的速度
A、甲乙两质点的速度-时间图象都在t轴上方，速度均为正值，都沿正方向，两个质点都做直线运动．故A错误．
B、甲的速度不随时间变化，做匀速直线运动．乙的速度增大，图线切线的斜率逐渐增大，加速度增大，所以乙做加速度增大的加速运动，故B正确．
C、根据“面积”大小表示位移，可知在0～t0内，甲的位移大于乙的位移．故C错误．
D、在t0时刻甲乙的速度相同，由于起点位置关系不清楚，无法判断两车是否相遇．故D错误．
故选：B

A man who reads lives many lives. A man who 50, walks the earth with blindfold. If I had to put all my 51 into a single word, it would be： browse（广泛阅读）.” Mr. Stone went on like that, 52 in a friendly and understanding tone. The 53of the class came 54 soon.
