Water habitats（栖息地） Most of Earth is covered with water. There are ponds, lakes, rivers, and oceans that are home to numerous（数量众多的） plants and animals. There are thousands of different animals that live in the ocean. Some of these animals are tuna, sharks, dolphins, and whales. Many other animals like oysters, crabs, starfish, and sea urchins live on the seashore（海岸） . Mammals（哺乳类） that live in the ocean breathe with their lungs. They can stay underwater for a long time, but they must eventually（最终） rise to the water’s surface for air. A whale is a mammal, and a shark is a fish. Whales breathe with their lungs. Sharks have gills instead of lungs to breathe with. In some place, oceans can be a very cold place to live. Some marine mammals are able to stay warm because they have thick skin or fur. Some of these mammals are the walrus, polar bear, whale, and seal. 翻译： 地球的大部分都被水所包围。 这儿的池塘， 湖泊， 河流， 还有海洋， 是地球上数量众多的植物和动物的家园。 这儿的海洋里居住着数以千计不同种类的动物。 他们中的一些是鲔鱼， 鲨鱼， 海豚和鲸鱼。 其中有一些住在海岸上， 比方说牡蛎， 螃蟹， 海星和海胆。 生活在海洋里的哺乳动物用他们的肺呼吸。 他们可以在水下呆很长时间， 但他们最终还是要浮上水面呼吸。 鲸鱼是哺乳动物， 可鲨鱼却是鱼类。 鲸鱼用他们的肺呼吸。 鲨鱼用作呼吸的是替代了肺的腮。 在某些地方， 海洋是一个非：涞木幼〉。 一些海洋哺乳动物只能够呆在温暖水域的原因是他们只拥有薄薄的皮肤或者是皮毛， 比方说海象， 鲸鱼， 北极熊还有海豹。 从句： （1） There are ponds, lakes, rivers, and oceans that are home to numerous（数量众多的）plants and animals.池塘， 湖泊， 河流， 还有海洋， 是地球上数量众多的植物和动物的家园。 （2） There are thousands of different animals that live in the ocean. 这儿的海洋里居住着数以千计不同种类的动物。 他们中的一些是鲔鱼， 鲨鱼， 海豚和鲸鱼。 （3） Mammals（哺乳类） that live in the ocean breathe with their lungs. 生活在海洋里的哺乳动物用他们的肺呼吸。 （4） They can stay underwater for a long time, but they must eventually （最终） rise to the water’s surface for air. 生活在海洋里的哺乳动物用他们的肺呼吸。 他们可以在水下呆很长时间， 但 他们最终还是要浮上水面呼吸。 (5) Some marine mammals are able to stay warm because they have thick skin or fur. 一些海洋哺乳动物只能够呆在温暖水域的原因是他们只拥有薄薄。 Most of Earth is c with （被覆盖） water.
