Ⅲ.阅读理解
I don't think I can recall a time when I wasn't aware of the beauty of the ocean.Growing up in Australia，I had the good fortune of having the sea at my side.The first time I went to Halfmoon Bay, I suddenly had the feeling of not being able to feel the ground with my feet anymore. For my 10th birthday，my sisters and I were taken out to the Great Barrier Reef.There were fish in different colors，caves and layers of coral.They made such an impression on me.When I learned that only 1 percent of Australia's Coral Sea was protected，I was shocked.Australian marine (海洋的) life is particularly important because the reefs have more marine species than any other country on earth.But sadly，only 45% of the world's reefs are considered healthy.
This statistic is depressing，so it's important for us to do everything to protect them.The hope that the Coral Sea remains a complete ecosystem has led me to take action.I've become involved with the Protect Our Coral Sea activity，which aims to create the largest marine park in the world.It would serve as a place where the ocean's species will all have a safe place forever.
Together，Angus and I created a little video and we hope it will inspire people to be part of the movement.Angus also shares many beautiful childhood memories of the ocean as a young boy，who grew up sailing，admiring the beauty of the ocean，and trying to find the secrets of ocean species.
