选项 _________(59)
A:when
B:since
C:so
D:whether
答案B
解析由本段第一句“… but the sudden sharp decline in three species of India ' s vultures...”可缸 此处是说秃鹰数量急剧下降。
由空后的"as”可知此处是考查固定搭配hte same as (和……相同的）。这里是说“和这些鸟住在同一地区的 人。
此处只能填across(在……各处，遍及），此处across the Indian sub-continent 表示"整个 印度次大陆"。above（在……上方）with (伴随，和……一起），through（穿越）用在此处均不合适。
第一段说秃鹰的急剧减少是一种警示而非值得庆贺的事，这给当地居民的生活带来了 很大的不便并造成了新的环境问题。这说明秃鹰在保护该区的环境上作用很大，所以秃鹰 不会是很少（rarely/seldom）起作用，或最近（recently)才起作用。只有选long（长期以来一直） 起作用才合乎上下文的意思。
下文说秃鹰以牛的尸体为食，秃鹰的急剧减少，导致同样以牛的尸体为实物的野狗大量繁殖，而狗是狂犬病毒的主要携带者，所以说秃鹰的存在对整个印度城乡环境的清洁起了很 大的作用。其他选项均不符合题意。smelly意为“难闻的，有臭味的”。
文章说，在印度，牛是一种神圣的动物，每年有成千上万头牛死亡后尸体暴露在野外。既然是这样，这些牛的尸体就不会是偶尔（occasionally)、立即（immediately）或几乎不（hardly) 暴露在野外。所以traditionally（历来，传统上）是正确答案。
本段第一句表达的是因果关系。"The disappearance of the vultures”是因，"an explosion in the numbers of wild dogs feeding on the remains of...”是果。lead to（导致）可以表达因果关 系，所以选A。
联系上文可知此处的“these…animals”指的是前边的死去的牛。这里是说，以牛的尸体 为食的秃鹰大量减少后，同样以此为食的野狗数量激增。
前边讲这种可怕的疾病最终可能会影响人类，空后说野狗是这种疾病病毒的主要携带 者，可见前后为因果关系，前边为果，后边是因。since可以表示“因为”，符合语境。
由后边的“an even greater problem”并联系前文即可确定答案为D。
从后面的“an emergency project has been launched（已启动了应急方案）”可以推断出要 选的形容词是urgent (紧迫的）。
科学家们是在寻找引起秃鹰死亡的疾病，如果可能的话找到治愈方法。identify表示 “找到，发现”，符合语境。prove（证明）,test (测试）,check(核实，检查）不合语境。
本段说秃鹰数量急剧减少，其中三种已被列为濒危物种。本题选deaths，正好与本段后 面一句“All three species are now listed as 'critically endangered'.”所表达的意思相照应。本句 的意思是，大规模的秃鹰死亡于19世纪80年代末在印度首次被注意到。
在四个选项中，along, on,in明显不合适。by有“到……的程度”的意思。"...the three species of vultures had declined by over 90 per cent”的意思是“……三种秃鹰的数量减少了 90％以上”。
“花费或用多少时间”英语的常用表达法是“……take＋时间＋其他”。故take是正确答 案。consume指“消耗”，虽也可指消耗时间，但用在这儿不如take合适。
