问题描述：
His mother _______ his father is busy with work.怎么填?
答
with
原因是原句为His mother is busy with work with his father
答
on / under / in front of
答
填 with
解析：有“is”主语就不能是复数，不是“and”，“with sb.”后固定加“is”，同样译为“他的妈妈和他的爸爸”，后半句“is busy with work”是固定用法“be busy with sth.”
翻译：他的妈妈和他的爸爸（都）忙于工作
答
as well as
这里考察的是主谓一致
因为谓语动词是is 就不能填and等并列连词
主语就是his mother
as well as his father插入
意思是他妈妈和他爸爸一样都忙于工作
答
His mother _______ his father is busy with work.
句中有is,即为单数,两个人之间填一个介词后,谓语用单数形式,可以考虑or,with
其中or,句意别扭,而with则句意通顺,填with最好
