Monarch butterflies(帝王蝶) from the eastern part of North America make the most amazing journey in the insect world. Each year, this tiny creature(生物) travels up to 3,000 miles(4,800 kilometers) to its winter home in central Mexico(墨西哥). How can it fly so far? And what is the purpose of its long and dangerous trip? Scientists still don’t have an explanation.

The length of the butterflies’ trip is only one part of the mystery. The other amazing thing is that the butterflies always return to the same place in central Mexico. How do the butterflies find their way back to the same place? This is an interesting question because only every fourth generation(代) makes the trip south. In other words, the butterfly that travels to Mexico this year is the great-great-grandchild of the butterfly that traveled there last year.

Each year, four generations of a Monarch butterfly family are born. Each generation of the family has a very different life. The first generation of Monarchs is born in the south in late April. It slowly moves north, reproduces, and then dies. On the trip north, two more generations are born, reproduce, and die. Each of these generations of butterflies lives for only two to five weeks. In the fall, the fourth generation of butterflies is born. Compared to its parents, this generation has a long life. It lives for about eight months. This generation of butterflies makes the amazing journey to the winter home of its great-great-grandparents. The butterflies spend the winter there, and in the spring they reproduce and then die. Their children will be the first generation of the next circle. How amazing it is!

Dear Isabel.

I have a mother, a father and a little brother. My dad p_______ houses for people. Sometimes he works at his office, and sometimes he works at home. Mum takes care of us. She also paints things, like flower pots and little signs for people's gardens and sells them. My little brother plays with trucks. That's pretty much all he does.

The nearest thing we did this summer was going to the beach. It was my first t________to the ocean. We drove all day from West Virginia to South Carolina(南卡罗莱纳州)and stayed in a hotel not too far from the beach. I loved the sand! We w________all along the seaside and found pretty stones and little sea animals that I had not seen before. I'll not forget the. sound of the waves as they rolled and rolled into the beach.

Do you think it's possible that you and I have touched the same water? My teacher says that waves in the ocean keep m________ all the time. Maybe the water on the beach in South Carolina comes from Canada.

Your pen friend,

Lucy
