In new research, scientists showed horses photographs of human faces, and they discovered that horses can distinguish between angry and happy faces and react accordingly.

The scientists fitted the horses with heart monitors which revealed that angry faces cause their heart rates to rise significantly.

Riders from a club in London also say that there is a special relationship between humans and horses. If you approach a horse and you are happy and relaxed, then the horse will be relaxed, too, and will help you. When you are not having a great day, the horse can make you feel much better.

The riders also said that the horses make people aware of their own emotions because they react to them.

Difficult words: distinguish (tell the difference), accordingly (appropriately), significantly (a lot), approach(come to).
