The university estimates that living expenses for international students ______ around $8,450 a year, which ____ a burden for some of them.
A are；are               B. is；are                 C. is；is          D. are；is    

答案

D

解析

试题分析：考查主谓一致，建议：这个大学估计国际生的生活费用是每年8,450美元，这对他们一些人来说是沉重的负担。第一空前面的主语是living expenses，所以谓语是复数，第二空的先行词是$8,450 a year,表示金钱，时间长度等，谓语是单数，选D。
