Most people, when they travel to space, would like to stay in orbit for a few days of more. And this stands to reason, if you’re paying $20,000 for your trip to orbit! Strain order for tourism to reach its full potential there’s going to be a need for orbital accommodation---or space hotels. What would a space hotel actually be like to visit? Hotels in orbit will offer the services you expect from a hotel------private rooms, meals, bars. But they’ll also offer two unique experiences: impressive views----of Earth and space---and the endless entertainment of living in zero gravity---including sports and other activities that make use of this.
The hotels themselves will vary greatly----from being quite simple in the early days to huge luxury structure at a later date. It’s actually surprising that as later as 1997, very few designs for space hotels were published. This is mainly because those who might be expected to design them haven’t expected launch costs to come down far enough to make them possible.
Lots of people who’ve been to space have described vividly what it’s like to live in zero gravity. There are obviously all sort of possibilities for dancing, gymnastics, and zero-G sports. Luckily, you don’t need to sleep much living in zero gravity, so you’ll have plenty of time for relaxing by hanging out in a bar with a window looking down at the turning Earth below.
Of course all good things have come to an end. Unfortunately, And so after a few days you’ll find yourself heading back enough you’ll be much more expert at exercising in zero gravity than you were when you arrived. You’ll be thinking how soon you can save up enough to get back up again---or maybe you should change jobs to get to work in an orbiting hotel.

这是一篇科普说明文,主要介绍了在太空旅行中住宿的地方――太空宾馆(space hotels),独特的体验如欣赏太空美景,在失重的状态下的无穷乐趣。读来也许会令你心驰神往的。
72. A 推理判断题。从第一段第一二两句 Most people, when they travel to space, would like to stay in orbit for a few days of more. And this stands to reason, if you’re paying $20,000 for your trip to orbit!和文章最后一段最后一句可推断出太空旅行因为价格昂贵目前只是少数人才能实现,但是这一切都是值得的,没有理由来了一次不去住space hotels.
73. B 细节推断题。从第一段最后一句But they’ll also offer two unique experiences: impressive views----of Earth and space---and the endless entertainment of living in zero gravity可知。其中A项未提及,C 项在第二段最后一句提到过但并非独特体验,D 项则未提及。
74. A 推理判断题。只有A项从未提及,B项在第一段最后一句提到过,C项在第二段可以找到依据,D项则在第三段进行了详细的介绍。
75. D 主旨大意题。从全文不难得出文章主要介绍了太空旅馆的情况。A项范围太广,B项以偏概全,C项不恰当并非介绍两者之间的关系。
Farming was once the chief way of life in nearly every country. People cannot live without food, and nearly all their food comes from crops and animals raised on farms. Not many people farm for a living any more, but farming remains the most important work in the world.
Before the nineteenth century, the typical American family lived on a small farm. They raised pigs, cattle, sheep, chickens, and planted corn, fruits, garden vegetables, and wheat. Everyone worked long and hard, but the results were often poor. Families barely harvested enough food for themselves. This situation began to change during the last half of the 1800's and it changed remarkably(明显地) in the next century.
Scientific methods and labor-saving machinery have made farming increasingly productive. The development of improved plant varieties and fertilizers has helped double and even triple the production of some major crops. More scientific animal care and animal raising have helped increase the amount of meat and products that animals produce. At the same time, the use of tractors and other modern farm equipment has sharply reduced the need for farm labor.
As farming has become less important as a way of life in the United States, it has become more important as a source which offers materials to industry. Today's successful farmers are experts not just in agriculture but also in accounting, marketing, and finance. Farms that are not run in a similar way have great difficulty surviving.
