问题描述：
Mr Smith,together with his wife and children,____in Shanghai 10 days ago .
A.is
B.are
C.was
D.were
(并说明原因）
答
A
with his wife and children是伴随状语，主要修饰Mr Smith
答
选A。因为Mr.smith后面加了个逗号，后面的together with…是用来补充他的。
答
选C，选A的人都没有注意10 days ago，要用过去时态。
答
is，together with在句中，谓语单复数与主语保持一致
答
C
这种复合主语取决于第一个主语,就是mr smith,根据时间状语 10 days ago,显然是过去式,所以选C was
