Have you ever thought, “ I wish I could take a year off and just travel around the world?”Well, three lucky American teenagers were able to do just that. The teens –two males and one female—got an all-expenses-paid, yearlong hike to five continents（五大洲）.

This trip didn’t include any five-star hotels or shopping funs. Eighteen-year-old Jamie Fiel from Keller, Texas, 17-year-old Arsen Ewing from Canyon, California, and 16-year-old Tyler Robinson from Lincoln, Massachusetts, didn’t expect fancy treatment. They signed up the experience of a lifetime, which included hard work, often uncomfortable accommodations, and encountered with some of nature’s most dangerous animals and environments.

  Jamie, Arsen and Tyler were among hundreds of high school kids nominated by their science teachers to take this trip. Earthwatch Institute sponsored(赞助) this adventure. Each year, Earthwatch employs thousands of volunteers worldwide to help with scientific research projects.

The group went all around the world to get a close look at the most pressing environmental issues of time.Their assignments(工作) were as varied as their locations, and included measuring and attending pink flamingos (火烈鸟) in Kenya’s Great Rift Valley, and tracking giant sea turtles in Costa Rica.

As they worked with the Earthwatch scientists, Jamine, Arsen, and Tyler began to understand that we are at a critical moment in the life of our planet. Time for change is running out. As the teens went from country to country and witnessed different environmental dangers and challenges, they understood that solutions to important environmental issues start with the power of one person’s actions. They realized that each of them can make a difference.

63. By whom were these three teenagers nominated to take this trip?

阅读下面短文，根据短文内容从每题所给的(A)、(B)、(C)、(D)四个选项中选出最佳答案。

　　Along with the Great Pyramid(金字塔) of Giza in Egypt, the Great Sphinx is one of the greatest and most studied monuments(纪念碑) of human history.

　　Carved(雕刻) from a single piece of stone of hundreds of tons, the Sphinx is the head of a man resting on the body of a lion.

　　The nose, eyes and ears have all been carved in the terrific proportions(比例). That's not easy for an object 180 metres long, 64 metres high and 35 metres wide.

　　No one knows what tools were used to carve the stone, when this was done, or by whom. The Egyptians wrote very little about the building of the Sphinx.

　　There are basically two schools of thought about how it was built.

　　No one knows what the Sphinx looked like when it was first finished because both natural erosion(侵蚀) and damage(破坏) done by man have changed its shape.

　　Many earlier pictures of the Sphinx show it with wings(翅膀), the body of a lion and ox(公牛), and the face of a man. Today only the man and the lion can be seen.

　　To this day, people can't agree with each other on the true role(作用) of the Sphinx.
