5 阅读理解。 The whole morning we just checked our own things. We were looking for items to give away. We thought of blankets, food and clothing. Our aim was not to find things we no longer wanted, but things we use every day and would be useful to others. We made up boxes with the things and added some small toys. Inside the boxes a simple letter was placed, reading: "Please take these items and know that your life is important. Times are difficult but they will pass. We share what we have, believing it will matter. Use the blanket to stay warm. Be safe and know that the human spirit can overcome anything. Don"t hold your head down. Someday please do the same when you can. How you do it and when, your heart will tell you. This kind act was not because the phone rang or for any reason. It was simply because it was the right time to do. We have often seen homeless people at the park where we left the belongings. The city would say that it isn"t a problem but I see the lives walking to and from it. I noticed that my wife had put her favorite green coat into one of the boxes. I asked if she was sure about it and she simply replied that it had a hood (风帽). She liked the coat but knew the hood could shelter (遮挡)someone from the rain. We don"t know where these gifts of compassion (同情) will go. We never go back and see what happens. It"s unimportant. The right things will find the right people and that is all that counts. On the way my wife started to cry. When I asked why, she said because some things felt so right. 1. What can we learn from the first paragraph about the couple? A. They had deep feelings of their work B. They often threw the useless daily items away C. They liked helping others by sharing their things D. They often gave away the daily items they didn"t use 2. The couple placed the letter inside the box mainly to______. A. help the poor go through the difficulties B. let the poor know who gave away the things C. tell the poor how to use the items correctly D. tell the poor to pass on the spirit to others 3. The couple liked this kind act because _______. A. they thought it was the right thing to do B. they had a good habit of saving things C. they often received telephone calls for help D. they hated being troubled by homeless people 4. What"s the best title for this passage? A. Boxes filled with compassion B. Good behavior leading to happiness C. The most important thing in our life D. Happiness coming from sharing things
6 2008年9月25日，我国成功发射了神舟七号载人飞船，在飞船绕地球作匀速圆周运动的过程中。下列说法中正确的是 A．知道飞船的轨道半径和周期，再利用万有引力常量，就可算出飞船的质量 B．宇航员从船舱中慢慢走出并离开飞船，飞船因质量减小，受到地球的万有引力减小，则飞船的速率减小 C．飞船的返回舱在返回地球的椭圆轨道上运动，在进入大气层之前的过程中，返回舱的动能逐渐增大，势能逐渐减小 D．若有两艘这样的飞船在同一轨道上，相隔一段距离沿同一方向绕行，只要后一飞船向后喷出气体，则两飞船一定能实现对接
