答案D,第2空为拜访她妈妈家
拜访 call on sb
call at some place
题目是拜访her mother's,是指她妈妈家,为地方,用call at
如果是题目是her mother,则用call on

call on 拜访，探望

yesterday the meeting____,because she had to____her mother's.
d.was called off,call at
call on +sb
call at + some place
都解释为拜访，但是后面所接的不一样

d.was called off,call at
called off取消
call at 拜访，后加一个地点
her mother's指的是“她母亲的家”
