5 阅读理解。 Robert and Peter study in the same university. They do everything together and help each other. But they often play jokes on each other. The school year was over last month and they decided to travel through the country in America. They drove a car and could stop wherever they were interested in and started whenever they wanted. Of course they enjoyed themselves. It was very hot one day and they were both hungry and thirsty. They stopped in front of a restaurant by the road. They came in, sat down at a table and ordered some dishes. Robert looked around and found there was a small bowl on the table. He thought there was some ice cream in it and took a spoonful of it and put it into his mouth. Immediately he knew it was mustard (芥末), but it was too late. Tears ran down his face, but he pretended nothing had happened. The other young man, seeing his friend crying, asked,"What are you crying about, Robert?" "I"m thinking of my father who was hanged twenty years ago," was a reply. After a while Peter made the same mistake. Tears ran down his cheeks, too. And his friend asked him why. "I wonder why your father hadn"t been hanged before he got married!" 1.

8 2013年12月2日，“嫦娥三号”探测器成功发射。与“嫦娥一号”的探月轨道不同，“嫦娥三号”卫星不采取多次变轨的方式，而是直接飞往月球，然后再进行近月制动和实施变轨控制，进入近月椭圆轨道。现假定地球、月球都静止不动，用火箭从地球沿地月连线向月球发射一探测器，探测器在地球表面附近脱离火箭。已知地球中心与月球中心之间的距离约为r =3．8×l0 5km，月球半径R=l．7×l0 3 km，地球的质量约为月球质量的81倍。在探测器飞往月球的过程中 A．探测器到达月球表面时动能最小 B．探测器距月球中心距离为3．8×l04 km时动能最小 C．探测器距月球中心距离为3．42×l05km时动能最小 D．探测器距月球中心距离为1．9×l05 km时动能最小
