We find that some birds (__) twice a year between hot and cold countries.
A. transfer
B. commute
C. migrate
D. emigrate
参考答案与解析
答案:C
解析:考查动词形近词辨析。句意:我们发现一些鸟每年都会在炎热和寒冷的国家之间迁徙两次。transfer转移,转让;调动;转车,换乘;commute乘公交车上下班,经常乘车(船)往返于两地;migrate(鸟、鱼等)(顺应季节定期地)移栖,迁徙;移居(尤指移居国外),与句意相符;emigrate(从本国往他国或外地)移居。结合语境,故正确答案为C。
