单选题
With the evolution of wings, insects were able to______to the far ecological corners, across deserts and bodies of water, to reach new food sources and inhabit a wider variety of promising environmental niches.
【正确答案】
B
【答案解析】解析：本题考查动词辨析。根据空后的the far ecological coiners(远方的生态角落)和deserts (沙漠)，bodies of water(水域)，new food sources(新的食物源)判断，昆虫能够到达这些地方，只有disperse(分散，驱散)符合语义，故为答案。relate意为“有关联；认同”。transgress意为“违背，违反(社会规范或道德准则)”。revert意为“恢复，回复(到以前的状态、制度或行为)”。
