1
The bright colors of coral reefs can be seen in warm seas all around the planet.
2
But they are not just beautiful, they are also hugely important to our oceans.
3
1. Corals are actually animals.
4
Though they may look like colorful plants, coral are in fact made up of tiny animals called polyps.
5
Polyps can range from the size of a pinhead to a bit larger than a basketball.
6
2. Corals are mega builders.
7
Each polyp builds itself a skeleton out of limestone.
8
These skeletons join together to form large colonies of hard corals.
9
As polyp colonies grow over hundreds and thousands of years.
10
They join with other colonies and become reefs that can stretch over hundreds of kilometers.
11
The largest coral reef is Australia's Great Barrier Reef.
12
It began growing about 20,000 years ago.
13
Three, coral reefs are some of the most diverse ecosystems on Earth.
14
Though they cover less than 1% of the ocean floor, coral reefs are home to 25% of all sea creatures.
15
Up to 2 million species live in coral reefs around the world.
16
4. Coral provide a window to the past.
17
As coral grow over thousands or millions of years, their limestone skeletons form layers.
18
These are similar to tree rings.
19
They vary in thickness based on ocean conditions at the time.
20
Scientists can study these layers to learn what the Earth's climate may have been like in the distant past.
21
But what about the future?
22
Unfortunately, climate change is dangerous for Earth's coral reefs, the animals that live there,
23
and the 500 million people around the world who depend on reef fish for food.
24
Unless we can slow down climate change, scientists warn that our oceans could lose many of their colorful reefs by the end of the 21st century.

什麼是跟讀法？
跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
