资源描述
Early in the 19th century, about 60 million bison lived on the Great Plains in North America. They were central to the existence of the Plains people. Then from 1830 to 1889 they neared extinction, with less than 1,000 still roaming. Today, they are a protected animal and there are well over 200,000 living in protected areas and ranches. I live in North America, however, I have some close relatives in Europe. I live in plains regions. I am able to survive cold winters. I roam out in the open on the Great Plains of North America, mostly in protected areas and private ranches. I have a massive head, a hump over my front shoulders and sharply pointed horns. I have a thick coat of dark brown and black hair. I am about 6.5 feet (2 meters) tall and about 9-12 feet (2.7-3.7 meters) long. Im quite heavy. I can weigh 1800-2400 pounds (850-1100 kg). I eat lots leaves and lots of grass. I have help getting protection now, because I was near extinction. But I do have horns and I usually hang out in a group with my friends. I first came to North American in prehistoric times when I crossed the Bering Strait land bridge from Eurasia. 译文野牛地图上涂绿色的地方是我的家有趣的常识:早在十九世纪, 约六千万野牛生活在北美大草原上。它们曾是草原人民的生活中心。然而从 1830 年到 1889 年,它们濒临灭绝,只有1000 只野牛尚存。今天,它们是保护动物,并且超过20 万只野牛很好地生活在保护区和农场。 我生活在北美,然而,我有一些近亲在欧洲。 我生活在草原地区,我能在寒冷的冬天生存。精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 1 页,共 8 页 我在北美大草原上露天闲逛,大部分是在保护区中和私人牧场。 我有一个大大的头,前肩上面有个隆起和一个尖锐突出的角。 我有着黑棕色的厚粗外衣和黑色的头发。 我大约 6.5 英尺 2 米高,约 9-12 英尺2.7-3.7米长。 我非常重,我能重达1800-2400 磅850-1100 千克。 我吃大量的树叶和草。 现在我受到了保护,因为我正濒临灭绝。但是我有角,我通常和朋友结伴出行。 在史前时期, 我从欧亚大陆穿越白令海峡、走过陆地、 桥第一次来到了北美。Red-crowned Cranes 丹顶鹤I am named for the cap on top of my head. 在中国我是和平与吉祥的象征。我们栖息在开阔的平原、沼泽、湖泊及近水滩涂。集中生活在中国的黑龙江、吉林、辽宁、长江中下游、台湾等地。俄罗斯、日本、朝鲜也是我们喜欢的聚居地。精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 2 页,共 8 页I am an excellent flyer and I can fly long distances.

They are often huge. They are meat eaters or plant eaters. But they do not exist any more. What killed the dinosaurs? Evidence(证据) shows that a huge meteor( 陨石) hit the earth about 65 million years ago. It raised millions of tons of dust into the sky, caused volcanoes to erupt(火山爆发), acid rain(酸雨) and even tsunamis( 海啸). Scientists think that all the dinosaurs died because of these changes to the environment. 精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 3 页,共 8 页What does the word dinosaur mean and how are dinosaurs named? Sir Richard Owen coined(造字) the word dinosaur, meaning fearfully(极) great lizard, in 1842. In Greek, deinos means fearfully great and sauros means lizard. There are many different ways to choose a dinosaur name. Sometimes the dinosaur is given a name that describes something unusual about its body, head or feet. Some are named after the location( 位置) where they are found. Others are named for their behaviour(行为) or size, and some are named to honour(尊敬) a person. The name has to be approved( 批准) by the International Commission on Zoological Nomenclature(国际动物学命名委员会 ). Pterosaur ( 翼龙) Diet: Meat eater It ate fish and squid(鱿鱼).

You can tell them apart pretty easily by their size. The African elephant has a larger body and big, floppy ears, while the Indian elephant is a little smaller and has small, stubby ears. I live on the continent of Africa and in the country of India. I live on plains and deserts and in tropical rain forests and river valleys. Im too big to have a house. I rarely lie down and usually sleep standing up. I have a large body with wrinkled skin and tusks made out of ivory. I also have a very long nose that I use to smell, make trumpet calls, rip leaves off trees and spray water on myself. I am gray, tan or light brown with yellowish-white tusks. I am very tall usually between 10 and 15 feet (between 3 and 4.5 meters)! Im huge! I can weigh between 11,000 and 15,000 pounds (between 5,000 and 7,000 kilograms)! I eat as much as 500 pounds (about 225 kilograms) of food each day! And 50 gallons (almost 90 liters) of water! My meals include leaves, grasses and other plants. My only real enemies are human hunters who value my ivory tusks. Even though I cant walk very fast, I have few enemies that are wild animals. I dont see very well, but my ears and nose make up for it! My famous nose allows me to smell food (or danger!) and lets me talk to my friends. 译文大象地图上涂蓝色的地方是我的家有趣的常识:精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 6 页,共 8 页象分为两大类非洲象和印度象。根据它们的大小,你能很容易将它们区分开。非洲象身躯比较大,耳朵大且松软下垂,而印度象要小一些,耳朵小且粗厚。 我住在非洲大陆和印度。 我生活在草原、沙漠、热带雨林和河谷。 我太大了以至于不能有个房子。我很少躺下,一般站着睡觉。 我有一个满是褶皱皮肤的庞大身躯和尖尖的象牙。我还有个非常长的鼻子,我用它闻味儿,当喇叭叫,从树上剥叶子,给自己洒水。 我是灰色、茶褐色或浅棕色的,象牙黄白色。 我非常高通常在10-15 英尺之间 ( 约 3-4.5 米之间 )! 我是巨大的!我的体重在 11,000-15,000磅之间 ( 约 5,000-7,000千克之间 ) ! 我每天吃 500 磅的食物!喝 50 加仑(将近 90 公升) 的水!我的饭包括叶子、草和其它植物。 我唯一真正的敌人是人类捕猎者,他们认为我的象牙很值钱。虽然我不能走得很快,但是我却没有什么野生动物为敌。 我的视力不是很好,但是我的耳朵和鼻子却弥补了这个缺点!我著名的鼻子使得我能闻食物 (或嗅到危险! ) ,并且让我和朋友交谈。Scientists agree that the dolphin is a very smart animal.
