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

Answer 1

A

句意：大学估计，国际学生的生活费用是＄8，450左右一年，对一部分同学来说是一个负担。本题考查是主谓一致，第一空的主语是前面的living expenses是一个复数名词，故用are；第二空中，作主语是前面的which，which引导的定语从句补充说明前面的living expense for international students are around ＄8，4508 a year这一件事，故用单数。 【考点定位】考查主谓一致。
