Reading 10A.

The Big Thor.

The Chacaltea ski area sits upon a small mountain glacier in Bolivia.

Although the area is less than a kilometer long, it once hosted international ski competitions.

In the past ten years, however, the snow has melted very quickly.

As the Chacaltea glacier melts, dark rocks are uncovered.

These rocks absorb more heat.

causing temperatures to increase so the remaining snow melts faster.

The cycle seems unstoppable.

Today the snow is almost gone, and so are Shakalteya's days as a popular ski resort.

A global problem.

In recent years, scientists all around the world have come to a terrifying conclusion.

Global warming is a real problem, and one largely caused by human activity.

But as experts debate how to solve the problem, ice near the North and South Poles is melting even faster than environmentalists once feared.

Ten years ago, scientists warned that the Arctic Ocean could lose all its ice in about a hundred years.

Now, they think it could happen much sooner.

As climate scientist

Mark Serres says, reality is exceeding expectations.

Glacier Run The ice sheet of Greenland is also melting more quickly than scientists predicted.

One of its largest glaciers, Jakobshavn Ispra, is moving towards the sea faster than expected.

In fact, the glacier is moving twice as fast as it was in 1995.

Rising air and sea temperatures are two well -known causes.

Researchers have also discovered other unexpected processes that cause glaciers to melt faster.

For instance, water from melting ice runs down cracks in the surface and gets between the ice and rock below.

This makes it easier for the glacier to slide into the warmer seawater.

Some researchers believe that the melting of Greenland's ice, if it continues, could add at least a metre to global sea levels by 2100.

If the ice sheet of Antarctica continues to melt at its current rate,

the next few centuries could see at least a 2 meter rise in sea levels, forcing tens of millions of people out of their homes.

Drying out While the melting of glaciers may flood some areas of the Earth, in other places, global warming is making water disappear.

Many scientists think the glaciers of the Himalayas and the Andes could disappear in this century.

As a result, millions of people in India,

Bangladesh, Bolivia, and Peru, who depend on water from mountain glaciers like Shakateya, could find themselves in a critical situation.

An increasing number of heat waves and droughts worldwide also suggest global warming is having an impact on humans right now now,

and that it could change the face of the world in the future.

How can we avoid these terrible consequences?

We all have a role to play in saving our planet, says Oscar -winning actor Leonardo DiCaprio, a producer of the documentary movie

Before the Flood, which helped to raise awareness of the problem.

DiCaprio believes that an immediate shift in people's attitude to climate change is needed.

We need to vote for leaders who understand the serious issues impacting our climate, he says.

There is no issue this important because the future of the planet is at stake.

如何用这段视频练习

先完整听一遍视频，不要开口，记下不认识的单词。
用正常速度逐句跟读，每句重复到你的节奏与说话人一致为止。
录下自己的声音并与原声对比，特别注意 melt, glacier, scientist 这类单词。

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。
