11、ule is far too demanding for long missions on the International Space Station (ISS). ISS crew members usually live in space for at least a quarter of a year.

14、gazines, photos and letters. And from early 2010, the Internet became available on the ISS, giving astronauts the chance to do some “web surfing (冲浪)” in their personal time.

18、earth from spaceDspend their free time in space答案与解析宇航员的生活往往是与众不同的，但是宇航员在国际空间站的生活可以跟他们在地球上的生活相似。他们可以与家人或者朋友联系，也可以进行一些日常活动。1B词义猜测题。由第一段中的“They work five days on and two days off.”可知，他们在尽量模仿在地球上的生活习惯，因此答案为B。2A推理判断题。由第二段可知在飞行前，这些宇航员的家人以及朋友为他们准备了照片、书籍等供他们消遣的东西，因此这些家人和朋友很体贴并且想法很周全。文章没有讲述宇航员的家人或者朋友对于这些宇航员
19、工作的担心与心烦，或者不耐心与心烦，或者兴奋与好奇，因此可以排除B、C、D。3D推理判断题。从最后一段可知，这些宇航员喜欢从窗口看宇宙和地球，并且地球在不同的时间呈现出不同的画面。4D主旨大意题。全文主要讲述了国际空间站的宇航员是如何度过闲暇时间的。B、C有一定的干扰性。文章提到了宇航员与地面上的家人和朋友联系，也提到了他们透过窗户看地球，但是这些都是细节，不是主题。.语法填空A young man, while traveling through a desert, came across a spring of clear water. _1_ water was sweet.
