生物多样性英语作文 篇1咳嗽喝蜂蜜水有用吗
Animals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sport, and simply becau they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.
Why should people care? Becau we need animals, and becau once they are gone, there will never be any more. Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks, the farmers' stores of corn and grain were destroyed by rats and mice. Why? Becau hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly.
Luckily, some people are working to help save the animals. Some groups rai money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger. Quite a few countries have pasd laws. The laws forbid the killing of any animal or plant on the danger list. Slowly, the number of some animals in danger is growing.
动物是自然资源，在整个历史过程中，人类一直在糟蹋着这种资源。人们杀死动物，获得它们的皮毛，把它们当作食物或运动方式，或者只是因为它们碍事。成千上万种动物已经从这个地球上永远地消失了。现在另外上百种动物也上了濒危动物名单。仅荚国大概就有170种被认为处于危险当中。
悠闲乡村生活为什么人们应该感到担忧呢？因为我们需要动物，因为它们一旦消失，就永远不会再出现。动物不仅仅是漂亮或有趣。它们不仅仅是人类的食物来源。在维持自然平衡中，每种动物都有其作用。毁灭某种动物会导致许多问题。比如，农民们如果杀死为数众多的鹰，他们谷物和粮食的仓库就会受到老鼠和田鼠的破坏。为什么？因为鹰吃鼠类，没有鹰控制它们的数量，鼠类就会迅速繁殖。湘西苗族服饰
幸运的是，有些人正在努力帮助拯救这些动物。有些组织筹钱以便人们了解这一问题。他们也努力使政府通过保护濒危动物的法律。很多国家已经通过了法律。这些法律禁止杀害濒危名单上的动植物。某些濒危动物的数目正在慢慢地不断上升。

Living things react
You and all organisms live in an environment. An environment is made up of
白起传everything that surrounds an organism. It can include air, the water, the soil, and even
other organisms. An organism responds to changes in its environment. When an organism responds to a change, it reacts in certain ways. All living things respond in some way. Have you ever noticed how plants and incts respond to light? Plants bed toward light. Incts fly toward light. Living things also respond in other way. The leaves on some trees respond to a change in ason. In autumn, they change colors and then fall off the branches.
Animals also respond to a change in ason. Squirrels save nuts for the winter. Bears sleep
through the winter in a cave. You respond to your environment in many ways, too. You
may shiver if you are cold. What other ways do you respond to changes in your
environment?
你和所有的生物生活在同一环境中。环境是由身边的一切组成的有机体。可以包括空气，水，土壤，甚至其他生物。生物体以某种特定的方式，对其环境所发生的变化做出反应。你有没有注意到，植物和昆虫对光有反应？植物向光生长，昆虫迎光飞舞。生物也会对其他东西产生反应。就像有的树叶会依据季节不同而呈现不同状态。在秋天，它们颜色变黄且脱落。动物也不例外。松鼠为过冬储存坚果。熊冬天睡在洞穴中。人对环境的反应是多形式的，就像冷的时候会颤抖。那么你对环境的变化会有怎样的回应呢？
