Question

【題目】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.

【2】C

【3】A

【解析】試題分析：這篇短文講述的是人類對火星的探索。人們覺得在火星上可能存在生命，于是開始去火星做太空旅行。但是去火星的天空旅行是很危險的，有很多失敗的例子。但是現(xiàn)在有兩個美國的機器人成功地在火星著陸了。他們可以幫助人類研究火星上是否有水或生命的跡象。

【1】細節(jié)理解題。根據(jù)短文第一段的最后一句話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。故選B。

【2】細節(jié)理解題。根據(jù)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，有兩個美國的機器人在火星上著陸了，這是去火星的最早的兩個機器人。他們可以幫助我們在火星上尋找水源或其它生命的跡象。故選C。

【3】細節(jié)理解題。根據(jù)短文最后一段的內容可知，這一段作者告訴我們火星被叫做死亡之星，意思是去火星做太空旅行是很難的，也是很危險的。作者還舉了一些例子說明這一點。故應選A。B和D只是這一段的一部分內容；C不是最后一段的意思。
