My hamster is running.

His brothers are playing golf.

Our friends are singing.

Her dogs are barking.

The mice are eating cheese.

Those women are dancing.

Explicación:

Con los pronombres you, we y they utiliza el to be en su forma are.

Con los pronombres he, she, it el to be se usa en su forma is. En el caso de las oraciones le presentan el sujeto a través de sustantivos, los cuales al ser reemplazados por pronombres es mas facil identificar la forma del verbo to be que les corresponde. Así "my sister" (ella) viene siendo she, "Tim and Tom" (ellos) viene siendo they. Así sucesivamente.
