7．MOOC，a massive open online course，（61）aims（aim）at providing large-scale interactive participation and open access via the web．MOOCs first made waves in the fall of 2011，when Professor Sebastian Thrun from Stanford University opened his graduate-level artificial（62）intelligence（intelligent）course up to any student anywhere，and 160，000students in more than 190countries（63）signed（sign）up．This new kind（64）ofonline classes is shaking up the higher education worid in many ways．Since the courses can be taken by hundreds of thousands of students at the same time．（65）The number of universities might decrease dramatically．Perhaps the most striking thing about MOOCs，many of （66）which are being taught by professors at famous universities，is that they're free．This is（67）certainly（certain）good news for cash-strapped students．There is a lot of excitement and fear surrounding MOOCs．While some say free online courses are a great way（68）to increase/of increasing（increase）the enrollment of minority students，others have said they will leave many students behind．Some critics have said that MOOts promote an unrealistic one-size-fits-all model of higher education（69）andthat there is no replacement for true dialogues between professors and their students．After all，a brain is not a computer．We are not blank hard drives（70）waiting （wait）to be filled with data．People learn from people they love and remember the things that arouse emotion．
分析 MOOC 是一种大规模的开放性在线课程，通过网络提供大规模的互动活动，深受人们的欢迎．关于它的利与弊，人们众说纷纭．
解答 61．aims 考查谓语动词．分析句子结构可知空缺处是该句的谓语，要填动词，再根据文中的时态可知该句应为一般现在时，主语MOOC是第三人称单数，要用第三人称单数形式的谓语动词aims，故填aims．
62．intelligence 考查名词．分析句子结构可知空缺处被形容词artificial修饰，要填名词，intelligent的名词形式是intelligence，故填intelligence．
63．signed 考查谓语动词和时态．根据上文可知该句讲述的是过去的情况，要用一般过去时，空缺处要填sign的过去式signed，故填signed．
64．of 考查介词．此处为固定短语a kind of+名词，意为"一种…"，故填of．
65．The 考查冠词．根据上下文可知高校的数量可能会戏剧性地下降，the number of …的数量/数字，故填The．
66．which 考查非限制性定语从句．根据语境和句子结构可知该处是非限制性定语从句，修饰先行词MOOCs，用关系代词which引导定语从句，故填which．
67．certainly 考查副词．空缺处修饰后面的形容词good，要用副词，certain的副词形式是certainly，故填certainly．
68．to increase/of increasing 考查固定搭配．"做…的方法"译为a way to do sth．/of doing sth..，故填to increase/of increasing．
69．and 考查连词．根据语境和句子结构可知动词said后跟两个并列的宾语从句，用连词and连接，故填and．
70．waiting 考查现在分词．根据语境"我们不是空白的硬盘驱动器，等着被填满数据"可知空缺处作后置定语，修饰名词drives，drives和wait之间是主谓关系，要用现在分词，故填waiting．
点评 考察学生的推理判断能力和联系上下文的能力，在做推理判断题不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．此类的填空题一定要联系上下文，根据上下文的内容加上自己的理解，再作出正确的判断．

16．
More recent research has shown that many kinds of amphibians（两栖动物） are declining or have become extinct．Amphibians are animals，such as frogs，that live partly in water and partly on land．And they have been around for over 350million years．They have （41）survived three mass extinctions，including the extinction of the dinosaurs．Why are they dying out now？
The most serious aspect of amphibian loss，however，goes beyond the amphibians themselves．Scientists are beginning to think about what amphibian （42）decline means for the planet as a whole．If the earth is becoming unlivable for amphibians，is it also becoming unlivable for other kinds of animals and human beings as well？
Scientists now believe that amphibian decline is due to several environmental factors．One of these factors is the （43）destruction of habitat，the natural area where an animal lives．Amphibians are very （44）sensitive to changes in their habitat．If they cannot find the right conditions，they will not lay their eggs．These days，as wild areas are covered with houses，roads，farms，or factories，many kinds of amphibians are no longer laying eggs．
There are a number of other factors in amphibian decline．Pollution is one of them．In many industrial areas，air pollution has （45）poisoned the rain，which then falls on ponds and kills the frogs that live there．In farming areas，the heavy use of （46）chemicals on crops has also killed off amphibians．Another factor is that air pollution has led to （47）increased levels of ultraviolet （UV） light．This endangers amphibians，which seem to be （48）especially sensitive to UV light．
All these reasons for the disappearance of amphibians are also good reasons for more general （49）concern．These factors affect human beings，too．
