Let's break down this phrase step by step. The sentence describes a hare, which is a type of rabbit. When it says 'the hare is pricking up its ears', this means the hare is listening carefully. Hares have big ears that they use to hear noises around them, especially sounds that might signal danger.
The next part, 'A rustle', refers to the sound of something moving through the grass or leaves. This could be another animal or the wind stirring up leaves. The word 'rustle' describes that soft, quick sound that catches the hare's attention.
Finally, when it says 'away it hops!', it means that as soon as the hare hears that rustling noise, it quickly jumps away to escape from whatever might be causing the sound. Hares are prey animals, so they need to be alert to stay safe from predators.
Overall, this phrase illustrates an important moment in nature where the hare is being cautious and reacting quickly to a potential threat. It’s a great example of how animals use their senses to survive!
