[00:00.00]和谐英语学习网 CHAPTER THREE
[00:-1.00]Reading page 39 to 40
[00:-2.00]Young and Green Magazine.
[00:-3.00]Continuing our series on endangered animals,
[00:-4.00]this month we talk to Professor Penny Sanders to...
[00:-5.00]GET THE FACTS ON WOLVES
[00:-6.00]1.Where do they live?
[00:-7.00]Wolves live in the northern half of the world,on three continents:
[00:-8.00]Europe,Asia and North America.
[00:-9.00]They are very adaptable:
[00:10.00]they can live in forests,on open plains,or in the snows of the Arctic
[00:11.00]2.What are they like?
[00:12.00]They resemble big dogs,with long legs, a wide head and thick fur.
[00:13.00]In fact,all of our domestic dogs probably came from wolves,many years ago
[00:14.00]They are about 1.5 to 2 metres long,
[00:15.00]and are about three-quarters of a metre in height.
[00:16.00]Provided that a wolf gets enough food,it will weigh about 40-50 kilograms
[00:17.00]3.What do they eat?
[00:18.00]Wolves usually eat small mammals such as mice,rabbits and deer.
[00:19.00]But they also hunt together to try to kill bigger animals
[00:20.00]such as moose and musk oxen.
[00:21.00]If they catch and kill a big animal,they eat as much as they can.
[00:22.00]Then they may not eat for up to two weeks.
[00:23.00]4,What is their family life like?
[00:24.00]There are about 6-8 wolves in a pack.
[00:25.00]Only one pair of wolves will produce cubs,
[00:26.00]but all the members of the pack will help to feed and look after the cubs
[00:27.00]If any danger threatens the cubs,the whole pack will protect the youngsters
[00:28.00]5.Are they dangerous to people?
[00:29.00]The wolf has a reputation as a fierce animal,
[00:30.00]and in many stories and films it attacks people.
[00:31.00]However,the truth is different.
[00:32.00]There is no proof that a wild wolf has ever harmed a human being.
[00:33.00]If you were in a forest and saw a wolf,it would run away from you.
[00:34.00]6.Are they in danger from people?
[00:35.00]Yes,very much so.
[00:36.00]Wherever people have spread in the world,they have killed wolves,
[00:37.00]usually to protect their own animals such as sheep and cattle.
[00:38.00]As a result,the numbers of wolves have been greatly reduced.
[00:39.00]They are extinct in many countries.
[00:40.00]In Britain, for example,wolves became extinct in about 1650.
[00:41.00]Similarly,there used to be many thousands of wolves in America.
[00:42.00]Now there are fewer than 2,000.
[00:43.00]If people had not come to America,
[00:44.00]wolves would not have disappeared.
[00:45.00]7.What is being done to help them?
[00:46.00]If we do not stop killing wolves,they will soon be extinct everywhere.
[00:47.00]People started to realize this 20 or 30 years ago,
[00:48.00]and slowly started programmes to protect wolves.
[00:49.00]In many European countries,the killing has now ceased,and wolves are protected by law
[00:50.00]In Germany, for instance,where there are now very few wolves,a campaign has started
[00:51.00]It has several objectives.
[00:52.00]One is to get better publicity for the wolf.
[00:53.00]If more people learn the truth about wolves,
[00:54.00]they won't hate wolves and won't want to kill them.
[00:55.00]Another aim is to preserve areas of the countryside in which wolves can live
[00:56.00]This would also be good for many other forms of wildlife.
[00:57.00]A third objective is to work out practical ways in which people
[00:58.00]and wolves can live together.
[00:59.00]Wolves cannot manage on their own.
[-1:00.00]Unless we help them in positive ways,they will disappear for ever.
