Coral reefs

For millions of years, coral reefs have provided homes and food for thousands of different living things. Fish and sea birds share the reef with other sea creatures. Now these beautiful places are in danger. 【1】 Scientists have found that people and pollution have ruined more than one-fourth of the earth’s coral reefs. Unless things change, all of the remaining reefs may die within your lifetime.

Some people think that coral is stone because of its rough, hard surface. But coral is an animal! Tiny polyps (水螅体) form the coral reefs. 2 These colours come from the algae (海藻) living inside the coral. Billions of coral polyps stick together. New ones grow on the dead corals. This happens year after year. Over time, the coral builds up a reef. The reef rises from the ocean floor until it almost reaches the sea’s surface. It takes coral 500,000 years to build a huge reef. 3

The coral reefs have been harmed in different ways. People have broken off pieces of coral. They wanted to sell or keep them. To catch more fish, people have dropped sticks of dynamite (炸药) into the water. 4 Water pollution has encouraged overgrowth of the sea plants that grow near coral reefs. They block out the sunlight that the algae need. 5 Warm water kills the algae. When the algae die, the coral loses both its food and its color. The coral turns white and dies. Scientists call this coral bleaching (珊瑚白化). The bleached part of the coral reef cannot recover.

A. They come in many colours.

B. This has blown up parts of the reefs.

C. So are all the sea plants and animals that depend on them.

D. The worst problem is the heating up of the world’s oceans.

E. Coral reefs are experiencing a rapid increase in most locations.

F. However, it has taken human beings less than 100 years to destroy the reefs.

G. They cover less than 1% of the ocean floor, but support about 25% of sea creatures.

【答案】

【1】C

【2】A

【3】F

【4】B

【5】D

【解析】

Here I am in the middle of a city, 350 miles far away from our farmhouse. Do you want to know why we move last week? Dad lost his job, and as Mom explained, He is lucky to find other one.

【题目】The Regional Director of the National Heritage Conservation Commission (国家遗产保护委员会) Kagosi Mwamulowe said the Barotse Plains is unique and it deserves to be on the list of the World Heritage Sites.

Mr. Mwamulowe said the Barotse Plains deserves to be included on the World Heritage List because it has a rich cultural heritage which includes the burial sites of former kings.

The Director said he hoped that the landscape would be declared as a heritage site next year in June. He also said it was important to protect Zambia’s unique culture for education and entertainment.

Chief Natural Heritage Officer Muyumbwa Ndiyoi said there will be a lot of benefits when the Barotse Landscape is declared a World Heritage Site because it will attract many tourists and business investments (投资) will increase.

Mr. Ndiyoi said the site will also benefit young people as knowledge will be passed down from generation to generation.

He was reacting to a question from Nalolo District Labour Officer Jason Ngoma who wanted to know how the people of Western Province will benefit once the Barotse Landscape is declared a World Heritage Site.

And University of Zambia Lecturer Charles Namate said there is a need for the site to be included on the World Heritage List because 50 years after its independence Zambia only has one heritage site, which is the Victoria Falls.

Lecturer Namate said the Barotse Landscape was facing a lot of environmental degradation (恶化), and that’s why there is a need to recognize the value of its landscape and the memories of dead kings.

A. the future of the Barotse Plains
