问题 Given our species’ increasing numbers and appetites which are reflected in and compounded by global climate change, even (i)________species are likely to become endangered within the foreseeable future. If we are to avoid a calamitous loss of biodiversity, according to Golbe, we cannot simply let nature take its course. Ongoing conservation management is (ii)________, as we have, in a sense, become nature, and the responsibilities that come with the role cannot be (iii)_________.
Blank (i)     Blank (ii)     Blank (iii)
A. exotic     D. ineffective G. jettisoned
B. vulnerable E. obligatory  H. assumed
C. now common F. promising   I. contrived

选项

答案C,E,G

解析 空格(i)填入形容词,修饰species,前面有even表让步,表示即使是怎样的物种也将濒临灭绝,所以空格(i)应该对become endangered取反,C项now common最为合适,表示即使是当前普遍的物种也可能遇到灭绝危险。空格(ii)表示对conservation management的态度,由于前句说我们不能对大自然袖手旁观(take its course的意思是任其自然发展),那么空格(ii)应该填一个表示“不任其自然发展”的词,E项obligatory(强制的)最为合适,表示必须人为干预。很多同学会错选F项promising(有远见的)。空格(ii)紧接着“不能对大自然袖手旁观”这句话,所以接下来应当提供一种解决方案而不是对于一件事情的评价,所以E选项更符合句意。空格(iii)表示对responsibility所采取的措施,由于有not,所以空格表达负向含义,与not连起来表示“责无旁贷”,G项jettisoned (放弃)最为符合。
