第一节(共H小题;每小题2分，满分30分)

阅读下列短文，从每题所给的四个选项(A、B、C和D) 中，选出最佳选项。

We are sailing toward the San Bias Archipelago,a chain of more than 360 islands in the Caribbean Sea.

“There's a boat!” Our daughter Hayley shouts suddenly.

Three men,far out at sea,are in a canoe called a cayuco. We pull up near them and they offer to sell us a spiny lobster(龙虾) ，but they have not caught enough for each of us.

“Un momento,por favor [One moment,please]，” the man says.

He dives overboard,holding his breath,goes down 40 feet, and comes back up with another lobster in his bare hands!We buy the lobsters and visit with the men.

These fishermen are the Kuna Indians from the San Bias Islands. The Kuna Indians have made their homes famous because of their efforts to protect their rain forests,their independence,and their culture.

For more than 400 years,the Kuna Indians have fought to keep their traditional way of life. They,ve formed their own system of government and laws. They,ye kept the Kuna language,though many speak Spanish,too. And while visitors are welcome,non-Kuna people are not allowed to own land.

Once we are on the island,we visit the sahila,or chief. It is an important part of Kuna culture for a visitor to receive an invitation and pay a fee to the sahila before entering,his village. We walk around the village and look at the way the Kuna people live. Kuna villages vary in size. They can range from a few dwellings（住所） to large villages with.some modem conveniences.

Hayley and her brother Jackson are being homeschooled while we are traveling on our boat. Part of our homeschool day is spent learning about the countries and people we visit. Earlier today we read about Kuna foods and money. The Kuna eat a lot of fish,lobsters and coconuts （椰子) .The coconut is also used for money. Each coconut tree has a Kuna owner,so the coconuts cannot be taken or touched.

21. According to the text,the Kuna Indians have been trying their best to.

A. expand their land

D. learn more about the outside world

22. Why does the author's family visit the sahila?
