Dear John,
I hope you are doing well. I am writing to share with you an unforgettable experience of voluntary work.
Last month, an international concert was held in Shenzhen. I took part in it as a volunteer. Before the concert, a foreign musician lost his way when he came out of the bathroom. He could not speak Chinese, so I used English to talk with him and finally guided him to his seat.
This experience made me realize how meaningful it is to do voluntary work. When I offer to help, I can feel the joy of supporting others. Besides, it also develops my skills of solving problems and communicating with others.
Do you have any interesting volunteering experiences Looking forward to your reply.
Yours,
Li Hua

D.24s
正确答案： A
答案解析： 物体位移与时间的关系是x=24t-6t2，与x = v t 1+ 20 at 2 对比，可知物体的初速度为
24m/s，加速度为-12m/s2，则它的速度为零的时刻是2s，故A正确。
2. 一物体以一定的初速度在水平面上匀减速滑动。若已知物体在第1s内的位移为8.0m，
在第3s内位移为0.5m，则下列说法正确的是( ) （10分）
A.物体的加速度大小一定为3.75m/s2
