Question

9．In the winters of 2012 and 2013，National Geographic grantee （被批准人） Anders Angerbjorn and his Ph．D．student，Rasmus Erlandsson，studied an extremely threatened species，the Scandinavian arctic fox，The current population numbers are fewer than 150 individuals in mainland Europe so many of the young foxes are having difficulty finding a non-related partner．Other threats to the species include competition from the red fox for the rare small rodents （啮齿目动物） they both depend upon for food．Angerbjorn and Erlandsson monitored the arctic fox population in Vasterbotten and Norrbotten，Sweden，to identify the best areas for further conservation actions．This included tagging （贴标签于） the baby foxes，which proved to be a challenge．
"When catching arctic foxes it is easy to believe that the smaller ones are the easiest to handle．In some aspects it is true．Their teeth are smaller and the jaws less powerful．However，just as human children have a hard time keeping still，the really small cubs （幼兽） do too．"
"We handle the foxes in a bag while tagging，and the trick is to keep the animal still between your legs while kneeling．And here comes the tricky part．How do you keep a small，wild fox still？You cannot apply too much force．You really do not want to hurt it．Just as with small children the best tool is patience，but at the same time you want the handling to be as short as possible．"
"One particular cub had a technique I had never experienced before as it continuously tried to turn onto its back，for no obvious reason．I had to reach the ears，so I quickly turned the cub upright．The cub stayed still for a few seconds，and then began to roll onto its back again．The same thing happened over and over again!Finally，I got the tags in place，and after making measurements and taking some samples，I finally let it go．"

A．brave                  
B．patient

Answer 1

分析 本文讲述了为了更好地了解一些动物的数量，科学家需要给动物贴上标签，这是一个需要耐性的活．

解答 DBCB
25．D 考查细节理解．根据"Other threats to the species include competition from the red fox for the rare small rodents （啮齿目动物） they both depend upon for food"可知，红狐与北极狐争夺食物．故选D．
26．B 考查细节理解．根据"Angerbjorn and Erlandsson monitored the arctic fox population in Vasterbotten and Norrbotten"可知，"this"指的是检查北极狐的数量．故选B．
27．C 考查细节理解．根据"However，just as human children have a hard time keeping still，the really small cubs （幼兽） do too"可知，第二段是为了举例说明很难给好动的小狐狸标上标签．故选C．
28．B 考查细节理解．根据"The same thing happened over and over again!"可知，为了给小狼崽贴上标签，需要很大的耐性．故选B．
