问题     We don’t have beds in the spacecraft, but we do have sleeping bags. During the day, when we are working, we leave the bags tied to the wall, out of the ways. At bedtime we untie them and take them wherever we’ve chosen to sleep.
    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)the sun "rises" and shines through our windows for about fifty minutes, then it "sets" as the spacecraft takes 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. When it’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 just above a seat, right next to a window. Before I pull the mask down over my eyes, I relax for a while, listening to music and watching the Earth go by under me. [br] The best title for this passage is_____.

选项 A、Traveling in Space
B、Sleeping in the Spacecraft
C、Equipment Used by Astronauts
D、The Earth Seen from Outer Space

答案 B

解析 通读文章后我们可以看出,本文通篇都在探讨宇航员在飞船里的睡觉问题。如:第一段介绍了宇航员在飞船里是睡在睡袋的;第二段介绍了宇航员可以同一时间睡觉;第三段介绍了为了更好的入睡宇航员会戴上黑色的睡眠眼罩;第四段介绍了宇航员睡觉时不同的睡姿以及本文作者的睡眠习惯。因此,B项是最佳标题。
