　　Mobile users can upload photos to a shared album. However, a shared album can’t be createdfrom a mobile device yet. Facebook programmers started designing the feature and put aworking version together in a matter of hours. But the _10_ of the feature more than eightmonths later shows the effort Facebook must now go through to deliver a version of somethingthat works for all of the 1.1 billion people on the social network.

　　解題思路

　　1.[N]空格位于副詞increasingly和名詞短語photo-sharing market之間，據此推斷此處應填入形容詞。本句提到Facebook, Google和Yahoo都加入到相片分享市場，可見這個市場的競爭很激烈，因此選用competi-tive最合適。

　　2.[K]此處應填入動詞原形或現在分詞與has構成has sb. do/doing的結構。共享相冊是一個創新(innovation)，再結合后面出現的幾家公司，可推知他們爭相占領這個市場。題庫中striving符合語義。

　　3.[H]空格所在的定語從句主謂賓齊全，由此判斷in...在從句中作狀語。本句指出，Facebook用戶可創建共享相冊，每個相冊上傳人數限定50人，每個人可以上傳200張照片。in可與名詞turn構成固定搭配，in turn “依次，輪流”符合語義。

　　4.[A]空格在定冠詞和名詞之間，可為形容詞、動詞分詞或名詞作定語。結合定語從句的描述：只有向上傳人、上傳人的好友或面向公眾開放，可知此處說的是關于隱私的設定，privacy符合語義。

　　5.[J]句子主謂賓齊全，判斷空格處應為副詞，修飾動詞expands。詞庫中副詞automatically“自動地”放人句中，句意通順，指出照片上的人一旦被加上標注，相冊會“自動”向其朋友開放。

　　6.[F]空格位于be動詞之后，可以為名詞、形容詞或為分詞。本句說的是有新照片加入共享相冊的時候，相冊的所有上傳人(each contributor)會怎樣。此處最適當的是notified，表示“得以告知”。

　　7.[G]空格所在句主謂賓結構完整，據此推斷空格應為副詞，表明保存照片的方式或地點。詞庫中只有副詞somewhere符合語境。

　　8.[B] or提示空格需填人動詞與前面的upload并列作句子的謂語，而且該動詞可以與into搭配。后面的intothe shared one提示，此處說的是將現有相冊放進共享相冊，merge符合語義。

　　9.[E]空格需要一個與is kicked out并列的動詞，本句提到照片的上傳者要去活動日志刪除照片的兩種情況，一種是他們被趕出去(is kicked out),另一種應該是“自動退出”，因此用leaves最適合。

　　10.[M]空格前的定冠詞the提示這里應填入名詞。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網絡，由此推知，只有“推出”共享相冊一段時間后，才能發現 產品的缺陷,從而進一步完善產品，release符合語境。

　　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.

　　解題思路

　　1.[F] as從句缺少謂語，此處應填人動詞?？崭袂懊嬲f到人口的增長,后面提到牲畜的數目，由此推斷填人空格處的動詞應與前面出現的increase意思相近，因此選multiply。

　　2.[G] and提示此處應是與buffalo并列的名詞。結合上文和空格后羅列的動物可知，空格處的名詞屬于某種livestock(牲畜)，名詞詞庫中的cattle最填合。

　　3.[J]空格處應為名詞、形容詞或分詞作part的定語。本句表明牲畜是地球物種的組成部分，critical “關鍵的”符合句意。

　　4.[E]空格前的really提示此處應填入形容詞或分詞。根據后面的“直到新報告發布”可知，在報告發布前牲畜的數量龐大到何種程度還是未知的，因此選apparent。

　　5.[A] more... than...表示的比較關系提示空格處應為動詞，且意思應與consume相對，因此yield為本題答案。

　　6.[0]此處應為副詞。rain forests將biologically sensitive land “生態敏感地區”的范圍進一步縮小，更加具體指出熱帶雨林受到的影響“尤其”嚴重，especially符合句意。

　　7.[N] more和and提示此處應填入與striking并列的形容詞，而且語義應比striking更進一步。本段講的是畜牧業造成了全球變暖，在形容詞詞庫中，alarming最符合句意。

　　8.[B]空格前的所有格提示此處應填入名詞。根據本句內容:畜牧業對全球變暖造成的影響高過運輸業。詞庫中的contribution “作用，影響”符合句意。

　　9.[H]此處應為名詞，且可與介詞for搭配。詞庫中可與介詞for搭配的名詞為passion,passion for meat意為“對肉類的愛好”,正好說明本段的觀點:想解決全球變暖的問題，不能簡單地靠少養牲畜或少吃肉。

　　10.[L]此處應填入定語成分修飾directions。這里是講解決全球變暖，應該將畜牧業推向什么方向發展?？梢姡崭裉帒钊牒蟹e極含義的詞,sustainable符合句意,sustainable directions意為“可持續發展的方向”。
