英语翻译
Millions of years ago there were many types of dinosaurs on earth.Most dinosaurs were plant?eaters.The Apatosaurus,for example,had a long thin neck so that it could eat leaves from trees.Other dinosaurs were meat?eaters.The Tyrannosaurus Rex killed smaller dinosaurs for food.
Dinosaurs were real animals that once lived on the earth,but they died out about 65 million years ago.The disappearance of the dinosaurs is in some way a great mystery (谜).① Some scientists think that the climate (气候) changed suddenly.Fossils (化石) of trees tell us that the temperature dropped a lot and that the level of the sea dropped as well.② This means that it got suddenly much colder.Perhaps the dinosaurs were too slow to change with the climate.
A new idea is that a meteor (流星) crashed into the earth.Scientists discovered a place in Mexico where they think the meteor crashed.They think that there was a lot of dust from the meteor.The dust landed on the plants.Also the dust blocked (阻挡) the sun's light for as long as five years.Many animals,including dinosaurs,were plant?eaters,and perhaps the dust killed them.This means there was nothing left for meat?eating dinosaurs to eat,and so they died out.But,as many animals from that time didn?t die,we are not 100% sure what really happened.
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 because they were in the way.Thousands of kinds of animals have disappeared from the world forever.Hundreds more are on the danger list today.About 170 kinds in the United States alone are considered in danger.①
Why should people care?Because we need animals.And because once they are gone,there will never be any more.
Animals are more than just beautiful and interesting.② They are more than just a source of food.Every animal has its place in the balance of nature (生态平衡).Destroying one kind of animal can create many problems.
For example,when farmers killed large numbers of hawks (老鹰),the farmers?stores of corn and grain were destroyed by rats and mice.Why?Because hawks eat rats and mice.With no hawks to keep down their numbers,the rats and mice multiplied(繁殖)quickly.
Luckily,some people are working to help save the animals.Some groups raise 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 passed laws.These laws forbid (禁止) the killing of any animals or plants on the danger list.Slowly,the number of some animals in danger is growing.

数百万年前有许多种类的恐龙在地球上.大多数恐龙是植物?食用者.这个迷惑龙,举例来说,有一个又长又细的脖子,可以吃树上的叶子.其他恐龙?肉.小恐龙霸王龙死亡的食品.
真正的动物,一旦恐龙生活在地球上,但是他们消失在6500万年前.恐龙的消失在某种程度上是一个谜(谜).①一些科学家认为,气候的变化(气候).树木的化石(化石)告诉我们,温度下降了很多,海平面下降.②,这意味着它突然冷多了.也许这个恐龙是太慢的气候变化.
一个新想法是一颗流星(流星坠落到地上.)科学家发现了一处位于墨西哥他们认为流星坠落.他们认为有很多灰尘从陨石.灰尘落在植物上.阻挡灰尘堵塞(也),太阳的光线长达五年之久.许多动物,包括恐龙,是植物?,也许这是灰尘食杀死他们.这意味着,什么都没有留下吃肉类?恐龙吃,所以就消失了.但是,随着越来越多的动物从那时候,根本?没有死亡,我们不是100%确定到底发生了什么事.
动物是自然资源,人们已经浪费了整个历史.
动物被杀,它们的皮毛,适用于食品、运动,因为他们在路上.成千上万种动物失踪的世界,直到永远.成千上百的濒危动物名单上.约170种仅在美国被视为危险.①
为什么人们关心吗?因为我们需要的动物.因为一旦他们消失了,不会有任何更多.
动物不仅仅是美丽而又有趣.②它们不仅仅是一种食物来源.所有的动物都在自然界的平衡(生态平衡).一种动物能破坏产生很多问题.
例如,当农民杀死了大量的鹰派(老鹰),农民们?商店里的玉米和谷物被老鼠.为什么?由于鹰吃老鼠.没有鹰来保存下来,他们的数字,老鼠繁殖增多(快速).
幸运的是,有些人正在努力拯救动物.有些组织筹钱来让人们了解这一问题.他们设法使政府通过法律保护濒危动物.
很多国家已经通过了法律.这些法律禁止(禁止)任何动物或植物的濒危动物名单.慢慢地,某些濒危动物的数目还在不断增加.
