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.
很多爬蟲動物沒有脖子，它們有四條有腳趾頭的腿，龜有堅硬的龜殼來保護它們的身體。蛇和其他的爬蟲動物不同因為它們的身體很長而且沒有腿。它們沿著地面來滑動前行。有些蛇還會游泳。 鳥是有羽毛在身上的動物。它們有不同種類的羽毛。有一些很小很蓬松，而有一些卻很長很平坦。羽毛有不同的顏色，鳥沒有前腳，取之代替的是一對翅膀。它們用翅膀來飛翔。但有些鳥沒有翅膀，像企鵝和鴯鹋，小小的粗而短的身軀。這些小鳥不能飛。鳥的身體由頭，脖子，軀干和尾巴組成。鳥喙是鳥的嘴巴。鳥喙的形狀取決于鳥以哪種食物為食。有些鳥像鴨子，它們有扁平的鳥喙來從泥土中篩選食物。其余的鳥像鷹，有硬和尖尖的鳥喙來抓住小動物和撕魚。 ——By lsy34
