The main reason we explore Mars is to determine if life ever existed on the planet. We have tried for centuries, starting with 【B1】______and lately with satellites, landers and rovers. We have 【B2】______ for it directly and indirectly. No luck so far. Some think life has never been there. Others think it was there in the past but is now gone. Many think why bother, but that’s a whole different story. I think we are 【B3】______in the wrong places. Here is why.
The surface of Mars is 【B4】______cold and dry. Cosmic and solar 【B5】______reach the surface by the thin atmosphere, and the soil contains strong oxidants (氧化剂) that destroy organic 【B6】______. Fat chance for life. But it wasn’t always so.
Early in its history Mars was warmer and 【B7】______enough for the development of rivers, lakes and perhaps oceans. The atmosphere was thicker and the protective magnetic (磁的) field was switched on. Mars might be 【B8】______today, but life would have been possible in the past. 【B9】______
But first we need to find a promising location, and that means reconstructing Martian history. 【B10】______, what type of minerals formed and if the geochemical conditions were compatible with life. Once promising sites are identified, we need to find out if there are 【B11】______ [br] 【B7】
选项
答案
wetter
解析
并列关系题。空格前是warmer,而and又连接两个词性和形式一致的词汇,因此空格处单词也应该是形容词的比较级。根据下文句意可知,原来火星上有河流、湖泊和海洋,可以推断出原来的火星很湿润,空格处单词应该具有“潮湿,湿润”之意。结合录音可知,答案为wetter。
