1
With its impressive tusks, wrinkly skin and majestic whiskers, the walrus is one of the Arctic's most iconic species.
2
Here are 10 facts everyone should know about these fascinating creatures.
3
Fact 1.
4
They're very big.
5
Male Pacific walrus can reach 3.6 metres long and weigh up to 1.8 tonnes.
6
The thick layer of fat under their skin, known as blubber, helps them to stay warm in the harsh conditions of their arctic home.
7
Fact 2.
8
Walrus are extremely sociable animals.
9
When on land or on ice, they gather together in tightly packed groups, which can include hundreds or even thousands of individuals.
10
Fact 3.
11
They can sing.
12
During the breeding season, from December to March, male walrus erupt into song.
13
They produce a variety of wonderful vocalisations.
14
These can include barks, clicks, grunts and bellows.
15
A bout of continuous singing can even last up to two and a half days.
16
Fact 4.
17
Both male and female walrus have large tusks.
18
Walrus use their impressive tusks to keep open breathing holes in the ice, to fight with other walrus and to defend themselves against predators.
19
They're also used to help haul themselves out of the sea and onto the ice.
20
Walrus tusks are actually modified canines which never stop growing and can reach up to 1 metre in length.
21
Fact 5.
22
Walrus have very sensitive whiskers.
23
Another distinguishing feature of the walrus is the many whiskers they have covering their snouts.
24
These whiskers are very sensitive and help them to snuffle around on the sea floor finding food such as mollusks.
25
Fact 6.
26
They depend on sea ice.
27
Walrus generally prefer to haul out on snow covered ice floes rather than on land.
28
They use the sea ice as a platform for resting, for breeding, for giving birth and nursing their young, as well as for shelter from rough seas and from predators.
29
Fact 7.
30
Their skin can change colour.
31
A walrus skin which can be around four centimeters thick around their head and their neck is generally a cinnamon brown colour.
32
However on a very warm day their skin can change to a rosy pink colour in the sun
33
and after a long swim in the icy cold water their skin can go to a cool white.
34
Fact 8.
35
Mothers are very protective.
36
The bond between a walrus mother and its calf is one of the strongest bonds in all mammals.
37
The pair can stay together for up to three years.
38
Walrus mothers are extremely protective and will pick them up with their flippers
39
and dive into the water when they come under threat.
40
Fact 9.
41
They're affected by noise and disturbances.
42
During their mass gatherings, walruses can be easily spooked, such as when they hear noise from human activities.
43
This can lead to stampedes as startled walruses head for the water.
44
This can be deadly, especially for young calves.
45
As shipping, tourism, industry and noise increases in the Arctic walruses are at greater risk of disturbance and also stampedes.
46
Fact 10.
47
Climate change is their greatest threat.
48
With sea ice melting due to climate change more walrus are being forced to rest on land.
49
This is bringing them further from their feeding grounds and leading to more life threatening stampedes.
50
We need to learn more about walrus to secure their future in the wild but accessing remote locations is challenging and costly.
51
We are working on a citizen science project that will use images from satellites to monitor walrus populations across the arctic.
52
For the first time ever we're aiming to do it at a global scale for the whole walrus population.
53
This will help scientists to better understand how walrus are responding to declining sea ice and how best to protect them.
54
We hope you enjoyed this video about walrus.

为什么用这个视频练习英语口语？

想要提升英语口语，选对素材很重要！这个关于海象的视频内容有趣、语速适中，涵盖了动物习性、环境问题等实用话题，非常适合用来做“shadowspeak”练习。一边了解海象的冷知识，一边模仿母语者的发音和语调，既能积累词汇，又能锻炼口语流畅度。比如视频里介绍海象“皮肤变色”“母子 bond 紧密”等内容，都是日常交流中可能用到的表达场景，练习时能轻松代入，让口语学习不再枯燥。

语境中的语法与表达

视频里有不少值得学习的实用表达，一起来看看：

  • “can reach... and weigh up to...”：用来描述事物的尺寸或重量，比如“雄性太平洋海象体长可达3.6米，体重高达1.8吨”。模仿这个结构，你可以说“这棵树能长到10米高，树干直径可达2米”。
  • “used to... as well as...”：表示“被用来做……，还能……”。视频中提到海象的獠牙“用来凿冰洞，还能自卫”，可以扩展为“这部手机用来通讯，还能当相机用”。
  • “With... more... are being forced to...”：描述因果关系，比如“随着海冰融化，更多海象被迫上岸”。这个句式在讨论环境问题时很常用，比如“随着城市扩张，更多动物被迫离开栖息地”。

发音易错点解析

视频里有些单词的发音容易出错，快来避开这些“陷阱”：

  • walrus：注意发音是/ˈwɔːlrəs/，不是“沃拉斯”，中间的“r”要轻轻卷舌。
  • blubber：意为“鲸脂”，发音是/ˈblʌbə(r)/，不要读成“布拉伯”，尾音要轻。
  • mollusks：指“软体动物”，发音是/ˈmɒləsks/，注意“s”的发音要清。

通过“看YouTube学英语”，结合“shadowspeaks”练习，多听多模仿，这些发音难题就能轻松解决。想要提高英语发音，不妨从这个视频开始，边学边练，让口语更地道！

什么是跟读法？

跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
