一項(xiàng)研究發(fā)現(xiàn)，自 1995 年以來，由于氣候變化導(dǎo)致海水變暖，澳大利亞大堡礁珊瑚數(shù)量下降了一半以上。

There is no time to lose. That’s the stark warning from Australian researchers about the health of the world’s largest reef system.

情況緊迫，時不我待。這是澳大利亞研究人員對世界上最大的珊瑚礁系統(tǒng)健康狀況發(fā)出的嚴(yán)厲警告。

They say its coral has been under a sustained attack by warmer seas driven by climate change. This causes bleaching.

研究人員們說，由于氣候變化導(dǎo)致的海水升溫，大堡礁的珊瑚受到了持續(xù)攻擊。這會導(dǎo)致珊瑚白化。

Under stress, the corals expel symbiotic algae which lives in their tissues and gives them their colour and energy.

面對環(huán)境壓力，珊瑚會排出生活在其細(xì)胞組織中，并為其提供顏色和能量的共生藻。

The study asserts that this is compromising the Great Barrier Reef’s ability to recover.

這項(xiàng)研究堅(jiān)稱，這損害了大堡礁的恢復(fù)能力。

1. True or false? Climate change has played a role in the loss of the corals.

2. What did the Australian researchers warn of?

3. What happens to the corals when they are under stress?

4. Where in the corals does symbiotic algae live?

答案

1. True or false? Climate change has played a role in the loss of the corals.
True. The warmer seas driven by climate change attacked the corals continuously, which causes bleaching.

2. What did the Australian researchers warn of?
The Australian researchers warned of the health of the world’s largest reef system – the Great Barrier Reef.

3. What happens to the corals when they are under stress?
When the corals are under stress, they expel symbiotic algae.

4. Where in the corals does symbiotic algae live?
It lives in the corals’ tissues.
