One of Australia's most famous natural gifts, the Great Barrier Reef is blessed with the breathtaking beauty of the world's largest coral reef. The reef contains a large variety of life and over 3,000 reef systems and hundreds of islands with some of the world's most beautiful beaches. Because of its natural beauty, the Great Barrier Reef has become one of the world's most sought-after tourist attractions.
However, for the past few years, the news about corals has been discouraging. Currently, the reef is threatened by climate change, tourism, water pollution, and overfishing. Agricultural fertilizer (肥料) run-off from Australian farms also has caused the widespread growth of sea-plants ,which absorb most of the nutrients (养分) and leave little remaining for the living coral reef and the animals that live in it. "What has changed is the increasing importance of climate change as a greater threat than the others," says David Wachenfeld, a scientist of the Great Barrier Reef Marine Park Authority. Coral reefs are extremely sensitive (敏感的) to warming ocean temperatures.
In a report on April 28, the Australian government said it set aside $ 500 million to help protect corals. The money will be spent on reducing water pollution from agriculture, reef monitoring and research on climate influence.
Though the Australian investment is welcome, it will at best only delay coral deaths. It's too little, too late, as a leading coral-scientist Terry Hughes of James Cook University put it. The only way to save corals over the long term is to slow down climate change. That process will require all countries to work together to find the most effective way of cutting emissions (排放) of greenhouse gases.
The most recent emissions figures, however, show that the world is failing at that task. The year 2019 has seen an increase in global emissions. This week in Bonn, Germany, countries are meeting to discuss how to keep their word in the Paris climate agreement. Let's hope they hear about the silent death of the world's corals.
We have studied in high school for several months. When I first (go) into the school and saw my new classroom and teachers, I thought I would have a new start. The school life is very busy and (excite). There are many activities in our school. We all take part in them (active). I have made many new friends and we often help and learn from each other in study. Our (teacher) have taught us a lot. They not only teach us how to study but also teach us how to be useful person in society. They also tell us is worth doing.
People often say, "There is no rule of learning." Now I feel it is true. The study now is far (different) than before. I often find there is something difficult (understand) at once. At this time, I must spend a lot of time (study) by myself, or I won't make progress.
Our school is clean and beautiful. There are many trees and flowers around . In order to make our school more and more beautiful, we should try our best.
, they would find a solution .
Process is important outcome. Please keep it in mind.
Instead, it's a virtue. You should the virtue.
is just try your best.
Every Saturday night Mama would count the money Papa had brought home. Among the money, the big silver pieces (be) for the rent, and the others were for the groceries. Mama always (tell) us that we needn't go to the Bank, and we were all so proud Mama's Bank Account.
Nels's going to high school would cost much money, and Mama took out a box was the "Little Bank" used for sudden (emergency). Although there was not enough money, Mama didn't want to go to Bank. Papa gave smoking, and Nels volunteered to work in Dillon's grocery after school. I promised to look the Elvington children every Friday night. So there was enough money and we needn't draw money out of Mama's Bank Account.
Twenty years later, I sold my first story. When the check came, I hurried over to Mama and asked her (put) it in her Bank Account. Mama looked at me and told me that there was no account at all. She just didn't want us to be afraid.
