Which sentence contains a linking verb?

Ellen could have chased the hockey puck into the corner.

The children are playing hockey on the frozen pond.

The hockey players have been anxious about the match.

Coach Tony has broken his hockey stick on the ice.

Respuesta :

the answer is no C because "anxious" is a linking verb
The children are playing hockey in the frozen pond. 
"Are" here is the linking verb because it does not show an action, but rather tells something about the subject. In this sentence, it tells more about the children that they are playing hockey.
