Question

my sister ,as well as one of her classmates who _

my sister ,as well as one of her classmates who ____late for class ,____criticized by Mr.Hunt. A.were ,was B.was,were C.was, was D.were, were 正解为A。求详解

Answer 1

第一空选择A是因为就近一致，即单复数取决于her classmates，所以选were。
第二空是主谓一致。一些主语后会出现介词短语as well as, as much as, no less than, along with, with, like, rather than, but, except, besides, including, in addition to等，表示复数意义，但谓语动词单复数只由主语中心语决定，即第二空的选择只看my sister，是单数，所以选was。

追问

为什么主语是my sister.而不是who前面的全部？？

追答

当as well as连接两个成分作主语时，其后谓语的单复数形式通常要与前面一个主语保持一致。如：
　　Tom as well as his parents is going to London．汤姆和他的父母要去伦敦。
　　The captain，as well as the other players，was tired．队长和其他队员都累了。

那为什么不选c

唉！我晕了！O:-)

追答

C与A的区别在第一空的选择，who were late for class是定语，修饰 classmates，而classmates是复数，所以用 were。
