The Pacific Ocean (太平洋) is the largest of the world’s four oceans. The Coral Sea is in the PacificOcean and is home to “one of nature’s greatest wonders”, the Great Barrier Reef. And the reef is now in danger.
It is the world’s largest coral reef system (系统). That is made up of about 3,000 different coral reefs. The reef is home to 400 kinds of coral animals and over 2,000 kinds of fish. Much of the life in the ocean calls the reef home.
However, global warming is causing a worse condition in the Great Barrier Reef. Rising ocean temperatures cause coral to give out the algae (海藻). The algae not only live in it, but also are the main food for the coral. Without it, the coral is still alive but is slowly becoming dead.
As even humans depend on coral reef systems for food, the death of the world’s largest coral reef system would be bad for the planet. Scientists hope they can help stop the global warming and protect nature’s wonders like coral reefs.

C．It has the most kinds of algae in the PacificOcean.
D．It is the only place where humans can get food from the ocean.
28．Why is global warming killing the GreatBarrier Reef
A．Because the algae are growing out of control with high temperatures.
B．Because the algae are becoming fewer with rising temperatures.
C．Because the algae have no place to live with rising temperatures.
D．Because the coral can only live in cool and comfortable environments.
29．What do the coral reef systems provide to human
A．Food. B．Medicine.
