Question

The teacher as well as her students-----skating in the gym every winter vacation.

a,goes,b,go,cwent,d,are going ,

Answer 1

先解释一下：
主语后跟有as well as, as much as, no less than, along with, like, rather than, together with, besides, including, in addition to等引导的词组时，其谓语动词的单、复数按主语的单、复数而定，也就是说，谓语动词的数不受这些词组的影响。
The teacher as well as the students was reading in the library. 这位老师和学生们一起在图书馆阅读。
The students as well as the teacher were reading in the library. 学生们和这位老师一起在图书馆阅读。
这里选A，首先as well as句子主语为the teacher，后面为单数；故排除B，D；
其次，因为句子里面说的是every，就是经常发生的动作；用一般现在时；故排除C；只能选A；

回答完毕，你看可以不，可以的话，请选为满意答案。希望对你有所帮助，如有疑问，请指出!

希望你学习进步，天天开心！

Answer 2

选择A ,这是对as well as的考察，连接两个主语是，按照“承前”原则，就是以前面那个为准。所以这句的主语就是The teacher，动词go当然就用goes（后面的every winter vacation表明是一般现在时）。

Answer 3

A as well as B 侧重A，故应该用单数，排除b、d.根据后文每个寒假，则表示经常性动作，应该用一般现在时选a
