问题 Communal nests have advantages and disadvantages for animals like voles and mice: they enable the animals to (i)______body heat, but leave them more (ii)______to discovery by predators.
选项
答案 A，E
解析 冒号说明前后同义重复。第一空设空处(i)——body heat体现好处，所以空格填入一个表示“加热”或者“保持”的词。maintain保持，squander浪费，stimulate激发。答案选A。第二空设空处more(ii)——to discovery by predators体现坏处，所以空格填入一个表示“容易”的词。immune不易受影响的，vulnerable易受攻击的，resistant抵抗的。答案选E。
