On most spacecraft flights everyone sleeps at the same time.No one has to stay awake to watch over the spacecraft; the craft's computers call us on the radio.On the spacecraft, sleep-time doesn't mean nighttime. During each ninety-minute orbit (轨道) thesunises and shines through our windows for about fifty minutes, then it sets as the spacecrafttakes us around the dark side of the Earth. To keep the sun out of our eyes, we wear black sleep masks. It is surprisingly easy to get comfortable and fall asleep in space. Every astronaut (宇航员) sleeps differently: some sleep upside down, some sideways, and some right side up. Whenit's time to sleep, I take my bag, my sleep mask and my tape player with earphones and float (漂浮) up to the flight deck (驾驶舱). Then I get into the bag, and float in a sitting position justabove a seat, right next to a window. Before I pull the mask down over my eyes, I relax for awhile, listening to music and watching the Earth go by under me.（分数：10.00）(1).When the astronauts are working, sleeping bags are fastened ______.（分数：2.00）A.on the wall √B.to their seatsC.onto the flight deckD.anywhere they like解析：解析：根据题目中的sleeping bags定位到第一段。

3.Task 2Directions：This task is the same as Task 1．The 5 questions or unfinished statementsare numbered 41 through 45．__________________________________________________________________________________________解析：Do you know how to use a mobile phone without being rude to the people around you? Talking duringa performance irritates (激怒) people. If you are expecting an emergency call, sit near the exitdoors and set your phone to vibrate (振动). When your mobile phone vibrates, you can leave quietlyand let the others enjoy the performance. Think twice before using mobile phones in elevators, museums, churches or other indoor public places—especially enclosed spaces. Would you want tolisten to someone's conversation in these places? Worse yet, how would you feel if a mobile phonerang suddenly during a funeral! It happens more often than you think. Avoid these embarrassing situations by making sure your mobile phone is switched off. When eating at a restaurant withfriends, don't place your mobile phone on the table. This conveys the message that your phonecalls are more important than those around you. Mobile phones have sensitive microphones thatallow you to speak at the volume you would on a regular phone. This enables you to speak quietlyso that others won't hear the details of your conversations. If you are calling from a noisy area,use your hand to direct your voice into the microphone. Many people believe that they can't live without their mobile phone. Owning a mobile phone definitely makes life more convenient, but limityour conversations to urgent ones and save the personal calls until you are at home.（分数：10.00）(1).What should you do when you need to answer a phone call during a performance?（分数：2.00）A.Call back after the performance.B.Answer it near the exit door.C.Talk outside the exit door. √D.Speak in a low voice.解析：解析：根据题目中的during a performance定位到第二段。
