Dear Liu Xiang:
How are you?I’m sorry to have heard that you got seriously injured before the 30th London Olympic Games,and unwillingly withdrew from the competition.It was a pity for you to lose the chance to compete in the race,but never mind.We all understand your situation and we will support you forever.
Having been your fan for several years,I was more than delighted to learn you’re recovering fast.I do hope you’ll return to the running track soon.Under no circumstances will a real hero be beaten down whether by frustration or by a temporary poor state of health.I believe,with the best medical treatment and your own stamina,you will get well in no time.I heartily wish you an early recovery and I’m expecting you to achieve more in athletics.
Yours sincerely,
XXX

中国女排历经挫折，再现辉煌，体现了矛盾双方在一定条件下相互转化和事物发展道路的曲折性，故②③入选。20年的奋斗历程体现了量变引起质变的道理，①入选。④说法太绝对。故选A。

解题思路：（1）物体间力的作用是相互的；
（2）相对于参照物位置不变的物体是静止的，位置不断变化的物体是运动的；
（3）物体由于惯性要保持原来的运动状态继续前进．

（1）刘翔起跑时用力蹬地的同时，地对刘翔也有力的作用，这是利用了力的作用是相互的；
（2）刘翔起跑后，跑道相对于刘翔位置不断变化，以刘翔为参照物，跑道是运动的；
（3）由于惯性，刘翔到达终点后不能立即停下来．
故答案为：物体间力的作用是相互的；运动；具有惯性．

点评：
本题考点： 运动和静止的相对性；惯性．

考点点评： 本题考查了物体间力的作用是相互的以及惯性知识；惯性是物体本身固有的一种性质，任何物体在任何情况下都具有惯性．

解题思路：AD、力的作用效果：可以改变物体的形状；还可以改变物体的运动状态；
B、根据力的作用是相互的进行分析；
C、物体能够保持原来运动状态不变的性质叫做惯性．

A、球与球拍撞击时，球拍发生形变是因为受到力的作用，A说法正确；
B、球撞击球拍，球拍给球一个反作用力，球撞击球拍的力和球拍对球的弹力是相互作用力的关系，故B说法错误；
C、球离开球拍后能继续飞行是由于球具有惯性，C说法正确；
D、飞行的球最终落向地面是因为受到竖直向下重力的作用，D说法正确．
故选B．

点评：
本题考点： 力的作用效果；惯性；平衡力的辨别；重力．

考点点评： 此题主要考查了力的作用效果及力和运动的关系，掌握基本概念，并能够用所学知识解释有关现象是关键．

sports career:in total,132 championship titles,including four Olympic champions

Won 14 times world champion,4 times an Olympic champion.

解题思路：平均速度等于总位移除以总时间，跟初末位置的速度无关，根据公式即可解题．

由题意知，运动位移为100m，跑完全程用时9.69s；
则平均速度v=[x/t]=[100/9.69]m/s=10.32m/s；
故选B．

点评：
本题考点： 平均速度．

考点点评： 本题考查对平均速度的掌握，注意排除干扰，抓住主要因素：位移与时间．

The characteristics of winners at the Olympics:

- attribute their success to a lack of thought (在成功之前,没有想太多,处之泰然）；
- relish the ride （享受过程）；
- care and don’t care about outcomes at the exact same time （几乎在同的时间在意和不在意结果）；
- understand that competition is the ultimate form of cooperation（清楚明白团队的重要性）；
- presume that they know little about their sport；
- feel pressure and think negative thoughts；
- use stillpower — not willpower；
- know that their perceptions are created from the inside out, their state of mind in the moment will determine their experience
