5 阅读理解。 It was a hot Sunday afternoon and the two of us were heading for the capital city. Suddenly my son gave a shout of pain. He had somehow managed to tangle up (围绕) his small body in his seat belt. I immediately pulled off the road. I could have tried to stop a car, but they were driving by so fast. At that moment, I would have cut the belt if I had something to cut it with. Then I thought that I could retract (缩回) little further in order that it might work. But if that failed, my son"s little stomach would be squeezed even tighter. Just then a man appeared. He wore a white shirt and trousers that I"d seen on Costa Rican cowboys and his clothes so dirty that I thought he might be a beggar or worse. Yet when the stranger reached us, he asked me if I needed help. I pointed to my son and he took a look. He then bent down beside my son, tracing the path of the smooth seat belt with with his rough fingers. After a long moment, he asked my son to bend sideways and a little bit forward. He then put his hands on the belt, controlled it in a way that I still don"t understand now, and my son was free. I thanked him warmly. I also reached into my wallet and gave him a bill, although his calm face suggested that he didn"t care about a reward. He had found a new way to use his roping skills, particularly those he used when freeing animals. And I had experienced the kindness. 1. What happened to the author"s son? A. He was unable to move in his seat belt. B. He suddenly suffered from a stomachache. C. He fell off his seat and hurt his stomach. D. He saw something interesting on the journey. 2. From the passage, we know the cowboy __________. A. taught the author how to free her son B. was familiar with the author"s son C. refused to accept the money D. was good at roping. 3. What would be the best title for the passage? A. cowboy in Costa Rican. B. A kind and quick roadside help. C. A hard journey D. A story of a cowboy

8 汽车以15m/s的速度在平直的公路上行驶，司机突然发现正前方15m处有一辆自行车以5m/s的速度做同方向的运动，在反应0.4s后才实施制动，这个时间称为反应时间。若汽车刹车时能产生的最大加速度为5m/s 2，则：（1）从司机发现自行车开始，到汽车停止，汽车还能继续运动多大距离？（假设汽车运动过程中没撞上自行车）（2）按题述情况，试判断汽车是否会撞上自行车？并说明理由．
9 （16分）某校化学实验兴趣小组为了探究在实验室制备Cl 2的过程中有水蒸气和HCl挥发出来，同时证明氯气的某些性质，甲同学设计了如下图所示的实验装置（支撑用的铁架台省略），按要求回答问题。（B中装的是无水硫酸铜）（1）装置A的作用是制取氯气，其反应的化学方程式为：（2）若用含有0.2mol HCl的浓盐酸与足量的MnO 2反应制Cl 2，制得的Cl 2体积（标准状况下）总是小于1.12L的原因是（3）①装置B的作用是，现象是。 ②装置C和D出现的不同现象说明的问题是。 ③装置E的作用是。 ④写出装置F中发生反应的离子方程式。（4）乙同学认为甲同学的实验有缺陷，不能确保最终通入AgNO 3溶液中的气体只有一种。为了确保实验结论的可靠性，证明最终通入AgNO 3溶液的气体只有一种，乙同学提出在某两个装置之间再加一个装置。你认为该装置应加在与之间（填装置字母序号），装置中应放入试剂。
