Chinese space lover Wang Yuan has been chosen as one of the volunteers for the Mars-500 test project. 【小题1】 Another five volunteers are all space. They are three Russians, an
Italy-Colombian and a Frenchman. They will feel what it's like to travel to Mars without leaving the earth. During the whole process (过程), they are locked up for one and a half years under the condition which is similar to the red planet. So the experiment is called Mare-500.

The main task is to study Man and Environment. It will care about the astronauts' physical
effects and the experience of staying there. 【小题4】 So they will have to make decisions by themselves and then report to the earth, and the earth will tell them whether they do the right thing or not.

(答案→)D 解析：短文大意:这篇短文主要介绍了火星—500计划。其主要内容就是志愿者将在一座与外面隔绝的大楼里面独自工作和生活十八个月，并将这些数据返回给地球，为人类登陆火星的计划提供研究数据。【小题1】联系前一句，中国的太空爱好者王元被选为火星——500载人航天飞行计划的志愿者之一。可知选D，他非常高兴当选，并愿意接受这个挑战。【小题2】联系下一句，尽管这些志愿者不会离开这座大楼，他们也会感觉好像他们真正的去火星旅行了。可知选C，这个火星—500测试会在莫斯科的一个特殊的大楼里面。【小题3】联系前文，最困难的事情是他们会与外面的人分离，及下文那会很困难。可知选B，他们会有十八个月看不到日出和日落。【小题4】联系下文，因此他们将不得不靠自己做决定，然后报告给地球……，可知选A，每个人都将在那儿独自工作和生活。【小题5】根据短文描述，可知这些志愿者在十八个月内独自工作和生活，可知他们会遇到很多困难，故选C。
