It can weigh up to 200 tons and live for nearly 90 years. It lives in all oceans except the Arctic. It eats tiny sea animals every day. When it dies, it feeds lots of sea creatures. Blue whales are very important to the ocean ecosystem. We must protect them. 提升版 The blue whale is the largest and heaviest living animal on our planet. It can weigh as much as 200 tons and live up to ninety years old. It travels across most oceans except the Arctic Ocean and feeds on tiny sea creatures. It eats around four tons of small sea life every single day. When a blue whale dies in the sea, its body becomes food for thousands of marine animals for over a year. It helps build a healthy ocean ecosystem. Blue whales are amazing creatures. We should stop polluting the sea and protect them forever. 范文 2 Bamboo 竹子 基础版 Bamboo is one of the most useful plants in China. It grows very fast, almost one metre a day. People build houses and make tools with it. Pandas love bamboo, and we eat bamboo shoots too. It stands for goodness in Chinese paintings. Bamboo is special and valuable to us. 提升版 Bamboo is one of the fastest-growing and most useful plants all over the world. It can grow nearly one metre within one single day. People use bamboo to build houses, make musical instruments and daily tools. Besides, bamboo shoots are delicious food for humans, and bamboo leaves and stems are the main food for pandas. What’s more, bamboo is a symbol of goodness in traditional Chinese culture, so it often appears in paintings. Bamboo brings us so many benefits, and it carries our beautiful culture as well. 范文 3 Bees — Important Insects 蜜蜂 基础版 Bees are the most important insects on Earth. Their main job is pollination. They carry pollen between flowers, so plants can grow fruit. They make honeycombs to store honey. But now there are fewer bees. We need to protect bees, or we will lose lots of fruits and vegetables. 提升版 Many scientists say bees are the most important animals on our planet. Their greatest task is pollination. When bees fly from flower to flower, they take pollen along with them, which helps almost eighty percent of plants grow fruit. Bees are also clever: they dance to tell partners where to find food and build neat honeycombs to store honey. However, the number of bees is dropping these days. If bees disappear, we will have almost no fruit or vegetables. We must try our best to protect bees to keep the balance of nature. 范文 4 We Can’t Live Without Plants and Animals 基础版 Humans can’t live without plants and animals. Plants give us fresh air and food. Animals keep nature balanced, like bees and blue whales. Many wild animals are in danger now. We should protect all living things, because we are connected. 提升版 Every person should understand that human beings cannot live alone without plants and animals. All living things are closely connected on the same planet. Green plants clean air and offer us fruit and vegetables. Small insects such as bees help crops grow, while large sea animals keep ocean ecosystems healthy. But lots of wildlife is losing homes and their numbers are becoming smaller. Protecting plants and animals means protecting ourselves. We should respect every living creature and take good care of nature. 学科网(北京)股份有限公司 $
