【题目】Monarch butterflies from eastern Canada make the most amazing journey in the insect world. Each year, this butterfly travels about 3000miles to its winter home in central Mexico(墨西哥). How can it fly so far? And why does it make this long and dangerous trip? Scientists still dont have an answer.

For many years, people in Mexico wondered where the orange-and-black butterflies came from every winter. Then, in 1937, a scientist started to follow and study the butterflies. For the next 20 years, he discovered that one butterfly started its journey in Canada. Four months later, it arrived in Mexico.

The length of the butterflies find their way back to the same place? Another amazing thing is that the butterflies always return to the same area 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 is born in the south in late April. It slowly moves north, reproduces(繁衍), and then dies. On the trip north,two more generations are born, reproduce, and die. Each of these generations of butterflies is born. This generation has a much longer life. It lives for about eight months. This generation of butterflies makes the amazing journey back 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 offspring will be the first generation of the next circle of life.

Today, people are still studying the Monarch butterfly. But they are not clear about everything.

【题目】Foods that are well known to you may not be familiar to people from different places around the world. Tourists and travelers often get to try some unfamiliar food. That is part of the fun of traveling. Here are four peoples experiences with foreign food.

David King is a Chinese student in France. I never had cheese or even milk before I came to France. Cows are seldom seen in my part of China. So there is no milk or milk products. I drank some milk when I first arrived in France. I hated it! I tried cheese, too, but I didnt like it. I love ice cream, though thats made from milk.

Birgit is from Sweden. She traveled to Australia on vocation. I was in a restaurant that was special in fish. I heard some other people order flake, so I ordered some, too. It was delicious! Later, I learned that flakes is an Australian name for shark. Now, whenever I see a new food, I try it on purpose. You know why? I remember how much I enjoyed flake.

Chandra is a dentist in Texas. She is from India. Im afraid to try new foods because maybe there is beef in them. Im a Hindu(印度教信徒)and my religion(信仰) stops me from eating meat from the cow. Thats why I cant eat hamburgers or noodles with meatballs.

Nathan is from the United States. He taught for a year in China. My friend gave me some 100-year-old eggs to eat. I didnt like their appearance at all. The eggs were green inside, but my friends said the color was normal. Chinese people put something on fresh eggs. Then they put them in the earth for three months. So the eggs werent really very old.
