Most reptiles do not have necks. Many reptiles have four legs with toes. Turtles and tortoises have hard shells which protect their bodies. Snakes are different from the other reptiles because their bodies are very long and they have no legs. They move by gliding along the ground. Some snakes can also swim. Birds are animals with feathers on their bodies. They have many different types of feathers. Some are small and fluffy and others are long and flat. Feathers come in many different colours. Birds have no front legs but instead they have a pair of wings. They use their wings to fly. But some birds have wings, such as penguins and emus are small and stubby. These birds cannot fly. The body of a bird is made up of a head, a neck, a trunk and a tail. The mouth of a bird is in the form of a hard bill or beak. The shape of the bill depends on the type of food the bird eats. Some birds such as ducks, have flat bills for sieving small bits of food from the mud. Other birds such as eagles have sharp, pointed bills for catching small animals and tearing fish.
很多爬虫动物没有脖子，它们有四条有脚趾头的腿，龟有坚硬的龟壳来保护它们的身体。蛇和其他的爬虫动物不同因为它们的身体很长而且没有腿。它们沿着地面来滑动前行。有些蛇还会游泳。 鸟是有羽毛在身上的动物。它们有不同种类的羽毛。有一些很小很蓬松，而有一些却很长很平坦。羽毛有不同的颜色，鸟没有前脚，取之代替的是一对翅膀。它们用翅膀来飞翔。但有些鸟没有翅膀，像企鹅和鸸鹋，小小的粗而短的身躯。这些小鸟不能飞。鸟的身体由头，脖子，躯干和尾巴组成。鸟喙是鸟的嘴巴。鸟喙的形状取决于鸟以哪种食物为食。有些鸟像鸭子，它们有扁平的鸟喙来从泥土中筛选食物。其余的鸟像鹰，有硬和尖尖的鸟喙来抓住小动物和撕鱼。 ——By lsy34
