Question

For a long time, humans have used technology (科技) to study the world around us, and Mars is the latest place we’re using machines to explore. Besides the earth, the “red planet” is seen, as the one place in our solar system most likely to have life.

Early last month, the first American robot, Spirit, landed on Mars without any problem. Opportunity, the second robot, landed on the planet more than a week ago. Scientists are very excited about these machines’ safe landing on Mars. It means that now we have an excellent chance to look for water and other signs of life. So far, the robots have found some stones that could show Mars was once a wet and warm planet.

But the trips made by Spirit and Opportunity were dangerous. Mars is often called the “death planet”, because in the past its environment has been unfriendly to the robot explorers. Before Spirit and Opportunity, nearly forty spaceships had been sent to Mars since the 1960s. Two-thirds of them failed. The first spaceship, Korabl, sent in 1962 by Russia was among them. It broke apart (分裂) near the earth.

【解析】

试题分析：这篇短文讲述的是人类对火星的探索。人们觉得在火星上可能存在生命，于是开始去火星做太空旅行。但是去火星的天空旅行是很危险的，有很多失败的例子。但是现在有两个美国的机器人成功地在火星着陆了。他们可以帮助人类研究火星上是否有水或生命的迹象。

1.细节理解题。根据短文第一段的最后一句话Besides the earth, the “red planet” is seen, as the one place in our solar system most likely to have life.可知，除了地球以外，火星上也可能存在生命。故选B。

2.细节理解题。根据短文第二段中Early last month, the first American robot, Spirit, landed on Mars without any problem. Opportunity, the second robot, landed on the planet more than a week ago.可知，有两个美国的机器人在火星上着陆了，这是去火星的最早的两个机器人。他们可以帮助我们在火星上寻找水源或其它生命的迹象。故选C。

3.细节理解题。根据短文最后一段的内容可知，这一段作者告诉我们火星被叫做死亡之星，意思是去火星做太空旅行是很难的，也是很危险的。作者还举了一些例子说明这一点。故应选A。B和D只是这一段的一部分内容；C不是最后一段的意思。
