Ⅰ．阅读理解
A new study suggests that dark markings n the planet Mars represent sand—nt water. The research in 2015 suggested that lines n sme Martian hills were evidence f water. Yet American scientists nw say these lines appear mre like dry，flws f sand. If water is present，it is likely t be a small amunt. Water in liquid frm wuld be necessary fr micrbial(微生物的) life.
NASA，the American space agency，said mre research is needed. Michael Meyer is the lead scientist fr NASA’s Mars explratin prgramme. He nted that the latest study des nt reject the presence f water. But he admitted，“It just may nt be as exciting as the idea f rivers ging dwn the sides f cliffs(悬崖)．”
The new findings cme frm a team led by Clin Dundas f the United States Gelgical Survey. His team measured 151 f these lines in 10 areas. Mst f the lines end with slpes between 28 degrees and 35 degrees. These measurements are similar t active sand dunes(沙丘) n bth Mars and Earth. A small cvering f dust that mves and smetimes becmes lighter might help explain the markings. They usually appear in the Martian summertime，and then disappear until the next year. If these lines are dry，this suggests that recent Mars has nt had large vlumes f liquid water. Dundas and his research team say that many questins remain.
“I still think that Mars has a great ptential fr having had life early n in its histry，” Meyer said. “As lng as that’s true，we als have a reasnable pssibility f life still being n Mars. It just happens t be cryptic r well hidden. ”
NASA currently has n rbtic vehicle—either n Mars r in develpment—with the ability t climb steep slpes. The lack f such equipment has engineers cming up with ideas like Martian helicpters r planes withut pilts.

文章大意：本文讲述了两个可以用来了解世界上最新的科学进展的网站，从而能让我们时刻追踪自己感兴趣的科学领域。
解析：
1．考查冠词。固定短语play a rle in 意为“在……方面起作用”，且very 为辅音音素开头的单词，因此用不定冠词 a。故填a。
2．考查定语从句。本句为定语从句修饰先行词 websites 意为“网站”，是一个具有地点意义的名词，从句中缺少状语，因此关系副词 where 在从句中作为地点状语。故填where。
3．考查非谓语动词。结合句意可知，这个网站报道科学新闻，并且涵盖范围广，有许多科目。cver在本句中用非谓语动词形式作定语，且与 science news 之间为主动关系，因此用 cver 的现在分词形式，对其进行进一步的解释说明。故填cvering。
4．考查介词。固定搭配be intended fr“专为……；打算为……所用”，故填fr。
5．考查连词。句意：这些文章是为年轻读者准备的，但是成年人也会发现这个网站适合他们。结合上下文语境可知为转折关系，故填but。
6．考查动词时态语态。句意：另外一个我每天浏览的网站叫做每日科学。网站名应该是被别人叫，因此应使用被动语态，文章时态是一般现在时，主语为Anther wnderful site谓语动词用第三人称单数形式。故填is called。
7．考查副词。空格后面为动词，副词修饰动词。故填cnstantly。
8．考查名词。根据空格后面的定语从句“that change hw we view the wrld”可知，that是引导词，change 是动词原形，说明前面的先行词为可数名词的复数形式。故填findings。
9．考查动词。根据空格所在句子“and als keep all the past articles they (psted) earlier”可知，过去的文章是过去的时间所发表的，因此动词应变形为过去式。故填psted。
10．考查主谓一致。根据空格所在的句子可知，that引导定语从句， 代替的先行词是 anything，因此谓语动词应为单数形式，且句子时态为一般现在时。故填is。
