问题 Large herds of grazing mammals are most likely to be found in a______.

选项 A、grassland
B、terrace
C、desert
D、forest

答案A

解析    (1)句子结构。
   本句的句子结构为主动补(SVC):主语为large herds of grazing mammals,are为系动词,most likely to be found…为主语补语(即表语)。
   (2)选项词义。
   A.grassland n.草原,牧草地
   B.terrace n.平台;梯田;阳台
   C.desert n.沙漠;荒原;应得的赏罚
   D.forest n.森林
   本句大意为“在草原上最有可能发现大群食草类哺乳动物”。根据句意,grazing mammals必定生活在grassland上,因此只有选项A符合题意。
