Researchers have identified 1. 4 million animal species so far—and millions remain to be discovered, named, and scientifically described. So how much would it actually cost to【S1】______every animal on Earth? A pair of Brazilian scientists has crunched (详细计算) the numbers and【S2】______up with an answer: $263 billion.
That’s way more than the $ 5 billion that famed Harvard University biologist Edward O. Wilson estimated back in 2000—and that was for every species on Earth, not just animals. But even $ 263 billion would be a【S3】______price to pay to understand the creatures that【S4】______such essentials as agriculture, fisheries, new drugs, and energy sources, says ornithologist (鸟类学家) Joel Cracraft of the American Museum of Natural History in New York City. "Literally, the world economy runs on biodiversity," he says. "People don’t understand really, deeply how much we depend on biodiversity."
Most biologists agree that with extinction rates【S5】______and climate change looming, the【S6】______to document the planet’s biodiversity—or biota (生物区)—is urgent,【S7】______considering the essential role these life forms play in crop pollination, clean air, and other aspects of human【S8】______"We are losing species by extinction faster than we are describing new species" according to some estimates, says biologist Antonio Marques, who【S9】______the new paper with Fernando Carbayo, both at the University of St. Paulo in Brazil. "We have to know the biota to preserve and conserve the biota," he says.
Besides the money, another huge【S10】______to a complete understanding of the animal kingdom is a global shortage of taxonomists (分类学家), experts say.
A) obstacle F) cheaper K) attempt
B) classify G) enable L) coauthored
C) especially H) come M) soaring
D) effort I) small N) well-being
E) identify J) exactly O) yet
【S2】
选项
答案
H
解析
固定搭配题。空格前为名词scientists作句子的主语,因此空格处应该填入动词,根据前面的并列结构has crunched可知,此处为动词的过去分词。空格后为介词up with,动词come与up with构成同定搭配,表示“想出,得出”。故选come。
