Question

Mr．Smith，together with his children，________come．Let's go now．

Answer 1

答案C
分析：主语部分是Mr．Smith，together
with
his
children，从意义上来说是“Mr．Smith和他的孩子一起”是复数的概念，但这里的together
with
his
children是个介词短语，主语的核心部分是Mr．Smith，是单数形式，整个主语要看成是单数。句意是“已经来了”，要用现在完成时，所以选C项has．(延伸)本句如果改为用and连接的话，就要看成是复数：Mr．Smith
and
his
children
have
come．(延伸)主语是“物”，带有with短语时，也同样要看这真正的主语“物”，不过此时的with要解释为“带有”的意思，如：The
flat
with
two
rooms
has
been
rented．(那套二室户已经出租掉了)
