Abralda, one of the largest coral reefs in the world, is truly an amazing place for scientific research. 1.

However, when we arrived there, things didn’t go as smoothly as expected. It was raining so hard that we couldn’t dive into the sea for reseach. What’s worse, we didn’t know how long we had to wait. 2. We did hope it would stop raining soon.

Since we couldn’t dive, we stayed on our boat that was meant to keep track of us when we were diving. 3. We dived quickly down in depth into a warm and colourful place. Meanwhile, the boat was following us all the way.

There were various sea creatures swimming around us. Interestingly, I was joined by a turtle which stayed on ray mask for a while. And it followed me during the rest period of my dive. 4. I was amazed and even shocked! Beautiful living coral covered nearly 100 percent of the bottom! Besides the turtle, many more sea animals passed by me closely. It was so fun. All stress, noise and troubles of life were left at the surface of the sea.

5. I dived for as long as I could that day. This was how I felt about Abralda—I loved it and never wanted to leave. In fact, we are already planning another diving research in Abralda.

A. It made us disappointed and upset.

B. We were dissatisfied and decided to leave there.

C. However, we had to do research on wildlife there.

D. I looked around to explore the fantastic underwater world.

E. Exploring so well underwater, I was unwilling to leave the sea.

F. Luckily, the rain stopped on the fourth day，and we went diving.

G. Therefore, we went to study and record the wildlife there months ago.
