     14-year-old Jason Morgan talks about an exciting science project.

     Last month I got the chance to take part in an underwater research project in an area of the Gulf of

Mexico called the Flower Gardens. A team of professional researchers' led by the scientist Dr Matt Phillips,

was trying to learn more about the fish and different creatures that live in this part of the sea. The Flower

Gardens are a long way from the shore (海岸) and we spent three days on a boat.

     The team used a piece of underwater equipment called ROV to collect information. The ROV was great fun. It was controlled by a computer on the boat, and I was allowed to operate it a few times. 

     However, the thing I enjoyed most was diving (潜水) into the water. At first, I was quite scared---mainly

because I couldn' t see land in any direction. But as soon as I jumped into the water, I wasn't afraid anymore.

It was amazing to see the colorful fish swimming around and I could see all the ways to the Flower Gardens,

which are almost 30 meters down. I will never forget the Flower Gardens. The trip was like a holiday but I also

learnt new things about science and research projects. It was a great opportunity and it has made me think

about my goals (目标) in life. The experience will help me work harder to become a scientist.
