     Because of my curiosity (好奇心), I had a really exciting weekend. I took a trip to Gloucester to see

some of the world's most beautiful animals-whales in the North Atlantic Ocean. After a long trip by train

and bus, we got on the ship called the "Privateer". On our way to see the whales on that beautiful sunny

day, I grew more and more excited.

     After a while we stopped, and everyone on the ship started to shout because we'd seen whales. It was

wonderful! 

     While we were watching the whales, a guide was giving us information about them. She told us we

were seeing only two kinds of whales-50-foot whales (singing whales) and 70-foot whales (the second

largest whales on the earth). She also said we could easily tell the different kinds of whales by their tales

(尾巴), since every whale has a different tail, just as people have different fingerprints (指纹).

     They all have names as well. On this trip, we saw "Salt" and "Pepper", two whales named by a scientist

and a fisherman. They swam together all the time. Sometimes whales came so close to the ship that we

thought we could touch them.

      I took twenty-seven photos, which was a really hard job because they moved so quickly, and stayed

on the surface of the ocean for such a short time. Having seen the whales was one of the chances few

people ever got. I was lucky enough to have that chance.
