【墨尔本PTE】PTE听力和口语一直是PTE口语考试中最重要的部分，今天墨尔本文波PTE培训学校给大家总结下PTE中的RL真题：
Dog growls
When this dog approaches some food, another dog’s playful snarls are played back. The dog seems curious, but the sound doesn’t stop it from taking the bone. Here a dog hears the growls of a dog being approached by a stranger, but these don’t deter it from grabbing the bone either. In another scenario, the sound of a dog protecting its food is played back. This time the dog backs off. These experiments suggest the dogs can distinguish between different types of growls.
