阅读理解。

     Diving around Halaveli Island was a really unforgettable experience. I participated (参加) in a day

diving trip that had lunch on the boat. We went to Maalhoss Thila first. The current (水流) can be very

strong here but we were lucky and had a mild one. We enjoyed all the different colors of coral and fish.

The maximum (最大) depth of this dive was 30m, and we stayed for about 40 minutes. The water was

reasonably warm, so I was not cold only wearing a short-sleeved (袖子) wetsuit.

     I was a bit worried about having lunch on the boat, as sometimes my stomach feels bad, but it was

perfectly fine this time -perhaps because the boat had not stopped and was moving toward the other

dive place, or because the size of the boat was reasonably large.

     Our next diving place was called Manta. And as expected, the huge Manta was soon around us. It

is one of the most exciting moments I have had in my life. We only dove to 14m this time, which allowed

us to stay a bit longer -almost 50 minutes.

     On the way back all the women took strategic position (好位置) on the deck, sunbathing and

relaxing, while the men were getting bored and ate the leftovers from lunch. No matter how different we

were, we all enjoyed our trip.

     Another dive I would like to recommend (推荐) is called Maaya Thila, and it is the best night dive I

have ever had. We saw a huge turtle (海龟) sleeping in a cave, and sharks (鲨鱼) playfully chasing (追

赶) each other. They did not look friendly at all, but fortunately they did not decided to have us for

dinner. But anyway what happened that night under water will remain a fond memory to be retold on

special occasions by all the participants (参加者). It will be told with a smile on our faces.
