有一句话这么说的:

This group of member is listening to the teacher carefully.

这句话是否有错误？

回答如下：

(1)a group of +复数名词，作主语，当作整体看待，谓语用单数

There is a group of monkeys in the innermost depths of the forest.
密林深处有群猴子。

(2)a group of +复数名词，作主语，当作个体看待，谓语用复数

A group of actors are rehearsing a play about Joan of Arc.  

一群演员正在排演一出关于圣女贞德的戏。

龙老师：

我觉得句子有误，其中的 member 应改为复数。又如：

This group of trainees is still under instruction. 这组实习生还在受训。

This group of chemicals is known to be harmful to the environment. 这类化学药品被认为对环境有害。
