　　解题思路

　　1.[N]空格位于副词increasingly和名词短语photo-sharing market之间，据此推断此处应填入形容词。本句提到Facebook, Google和Yahoo都加入到相片分享市场，可见这个市场的竞争很激烈，因此选用competi-tive最合适。

　　2.[K]此处应填入动词原形或现在分词与has构成has sb. do/doing的结构。共享相册是一个创新(innovation)，再结合后面出现的几家公司，可推知他们争相占领这个市场。题库中striving符合语义。

　　3.[H]空格所在的定语从句主谓宾齐全，由此判断in...在从句中作状语。本句指出，Facebook用户可创建共享相册，每个相册上传人数限定50人，每个人可以上传200张照片。in可与名词turn构成固定搭配，in turn “依次，轮流”符合语义。

　　4.[A]空格在定冠词和名词之间，可为形容词、动词分词或名词作定语。结合定语从句的描述：只有向上传人、上传人的好友或面向公众开放，可知此处说的是关于隐私的设定，privacy符合语义。

　　5.[J]句子主谓宾齐全，判断空格处应为副词，修饰动词expands。词库中副词automatically“自动地”放人句中，句意通顺，指出照片上的人一旦被加上标注，相册会“自动”向其朋友开放。

　　6.[F]空格位于be动词之后，可以为名词、形容词或为分词。本句说的是有新照片加入共享相册的时候，相册的所有上传人(each contributor)会怎样。此处最适当的是notified，表示“得以告知”。

　　7.[G]空格所在句主谓宾结构完整，据此推断空格应为副词，表明保存照片的方式或地点。词库中只有副词somewhere符合语境。

　　8.[B] or提示空格需填人动词与前面的upload并列作句子的谓语，而且该动词可以与into搭配。后面的intothe shared one提示，此处说的是将现有相册放进共享相册，merge符合语义。

　　9.[E]空格需要一个与is kicked out并列的动词，本句提到照片的上传者要去活动日志删除照片的两种情况，一种是他们被赶出去(is kicked out),另一种应该是“自动退出”，因此用leaves最适合。

　　10.[M]空格前的定冠词the提示这里应填入名词。后面提到，Facebook要做出努力(shows the effortFacebook must go through)以推出面向很多人的社交网络，由此推知，只有“推出”共享相册一段时间后，才能发现 产品的缺陷,从而进一步完善产品，release符合语境。

　　When you think about the growth of human population over the last century or so, it is all tooeasy to imagine it merely as an increase in the number of humans. But as we _1_, so do all thethings associated with us, including our livestock. At present, there are about 1.5 billion _2_and domestic buffalo and about 1.7 billion sheep and goats. With pigs and poultry, they form a_3_ part of our enormous biological footprint upon this planet.

　　Just how enormous was not really _4_ until the publication of a new report, called “Livestock’sLong Shadow,” by the Food and Agriculture Organization of the United Nations.

　　Consider these numbers. Global livestock grazing and feed production use “30 percent of theland surface of the planet.” Livestock—which consume more food than they _5_—alsocompete directly with humans for water. And the drive to expand grazing land destroys morebiologically sensitive land, rain forests _6_, than anything else.

　　But what is even more striking, and _7_, is that livestock are responsible for about 18 percentof the global warming effect, more than transportation’s _8_. Greenhouse gases, such asmethane and nitrogen，are resulted from their digestion. Grazing land, which destroys forests,adds to the effect.

　　There are no easy trade-offs when it comes to global warming—such as cutting back onlivestock to make room for care. The human _9_ for meat is certainly not about to end anytimesoon. As “Livestock’s Long Shadow” makes clear, our health and the health of the planetdepend on pushing livestock production in more _10_ directions.

　　A)yield B)contribution C)stain D)ideally

　　E)apparent F)multiply G)cattle H)passion

　　I)scrape J)critical K)liable L)sustainable

　　M)deposit N)alarming O)especially

　　解题思路

　　1.[F] as从句缺少谓语，此处应填人动词。空格前面说到人口的增长,后面提到牲畜的数目，由此推断填人空格处的动词应与前面出现的increase意思相近，因此选multiply。

　　2.[G] and提示此处应是与buffalo并列的名词。结合上文和空格后罗列的动物可知，空格处的名词属于某种livestock(牲畜)，名词词库中的cattle最填合。

　　3.[J]空格处应为名词、形容词或分词作part的定语。本句表明牲畜是地球物种的组成部分，critical “关键的”符合句意。

　　4.[E]空格前的really提示此处应填入形容词或分词。根据后面的“直到新报告发布”可知，在报告发布前牲畜的数量庞大到何种程度还是未知的，因此选apparent。

　　5.[A] more... than...表示的比较关系提示空格处应为动词，且意思应与consume相对，因此yield为本题答案。

　　6.[0]此处应为副词。rain forests将biologically sensitive land “生态敏感地区”的范围进一步缩小，更加具体指出热带雨林受到的影响“尤其”严重，especially符合句意。

　　7.[N] more和and提示此处应填入与striking并列的形容词，而且语义应比striking更进一步。本段讲的是畜牧业造成了全球变暖，在形容词词库中，alarming最符合句意。

　　8.[B]空格前的所有格提示此处应填入名词。根据本句内容:畜牧业对全球变暖造成的影响高过运输业。词库中的contribution “作用，影响”符合句意。

　　9.[H]此处应为名词，且可与介词for搭配。词库中可与介词for搭配的名词为passion,passion for meat意为“对肉类的爱好”,正好说明本段的观点:想解决全球变暖的问题，不能简单地靠少养牲畜或少吃肉。

　　10.[L]此处应填入定语成分修饰directions。这里是讲解决全球变暖，应该将畜牧业推向什么方向发展。可见，空格处应填入含有积极含义的词,sustainable符合句意,sustainable directions意为“可持续发展的方向”。
