He with his mother _____at home.

问题描述:

He with his mother _____at home.

He with his mother _stays/is/was___at home
他和他妈妈在家。在家短语为be at home /stay at home
至于谓语动词是用单数,是因为with不是连词,如果是用复数应用and连接
with his mother 只能算是伴随状语

is / was/stays...
总之用单数形式啦
因为这里真正的主语其实是he ,虽然这里看上去是两个人应该用复数了,但是with 后的名词是连带的,如果两者是由and连接,那是并列,就应该用复数了

is/stays

填、
stays.
