9分)某同学利用打点计时器探究小车速度随时间变化的关系,所用交流电的频率为50Hz,如图为某次实验中得到的一条纸带的一部分,0、1、2、3、4、5为计数点,相邻两计数点间还有1个打点未画出.若从纸带上测出x1=5.20cm、x2=5.60cm、x3=6.00cm、x4=6.40cm.则打点计时器打计数点“2”时小车的速度v2=    m/s,小车的加速度a=___   m/s2,依据本实验原理推断第4计数点和第5计数点之间的距离x5=   m.(结果保留三位有效数字)

阅读下列短文,从每题所给的A、B、C、D四个选项中,选出最佳选项。

I found the imagination of becoming a grandmother somewhat discouraging. I was younger than I thought a grandmother should be when I got the news that I was going to become one myself. I admit, it was not a role that I was emotionally ready to accept. I had been a young mother, and had certainly hoped my daughter would not face that same challenge. I remarried when she was a teenager, and then had two more children. On getting the news that she was expecting(怀孕), I remember thinking “What do I know about being a grandmother? —I haven’t even finished raising my own kids yet!” I don’t like to be unprepared, so I read a few books about grandparenting. That gave me a little help, but I was still uncertain. I thought about other grandmothers I knew, and got a few ideas I liked and a few more that I didn’t. But I couldn’t quite figure out what kind of grandmother I wanted to be. Then I thought about my own grandmother, Granny, as she’s known by most people, and I knew I had the answer.

I didn’t realize it until that moment, but my own grandmother was the example for the kind of grandmother I wanted to be. I am fortunate that I got to spend a lot of time with my grandparents when I was a little kid. Here is what I learned from my Granny:

Grandmothers always have a cookie jar. For my whole life, Granny always had a cookie jar full of cookies. When I was a little tiny girl, just at eye level with the counter, Granny would get the cookie jar down for me. When I was a little older I learned how to pull the chair over so I could reach. As I got taller, if I really stretched, I could reach the cookie jar with my finger tips and move it close enough to get it down off the counter to find out what kind of treat was inside. Always the first thing I did when I went to Granny’s house was check the cookie jar, and there were always cookies in it. Many years later, I’ll drive my own children to Granny’s house and the first thing to do is get us all a cookie.

So grandmothers must have a cookie jar, and on my granddaughter’ s first Christmas,my daughter bought me my own cookie jar. She said when they came to see me,her daughter would find the treat the way she did and I did.
