3.An expert, together with some assistants, ____ to help in this
work.
A. was sent B. were sent C. is sending D. are sending

翻译

a.was sent.together with some assistants是插入语，主语还是an expert，所以选谓语是单数。由于专家是被“送”的，所以选a

选A,
填空处是对expert的补充说明,expert是单数,所以排除B,D.
expert是"被"请去的,所以要用被动语态.所以排除C.

选B，就近原则
一位专家和他的几个助手已经被派出帮助这项工作了。

a

一个专家和一些助手被带来帮助完成这项工作

一个专家和一些助手被派去王成这项工作

A. was sent
