British royals William and Kate have launched their first official YouTube channel with a 25-second clip taken from official royal engagements.

The clip included Kate shooting an arrow, William working in a kitchen, Kate shearing a sheep during a visit to a farm, and William sitting with Sir David Attenborough promoting an environment prize, among other moments.

William and Kate already use Twitter and Instagram to promote their work.

Difficult words: royal (connected with the king or queen), engagement (an official meeting), shear (to cut the wool off a sheep or other animal like a sheep).
