Question

Katy,with her sister Sandy,        visit her Aunt Peggy.

A. are going to    B. is going to    C. are going

Answer

B

【解析】

句意：凯蒂和她的妹妹桑迪要去看望佩吉姨妈。考查主谓一致。A. are going to：将要做某事，主语是复数时；B. is going to：将要做某事，主语是单数时；C. are going，将要做某事是be going to do sth.，排除C。本句主语Katy，with和，介词，with her sister Sandy是伴随状语；主语Katy是单数，故谓语用单数，选B。
