The oldest domestic dogs in the Americas were thought to be around 9500 years old. Angela Perri of Durham University, UK, and her colleagues have carried out fresh radiocarbon dating on the two dog skeletons that gave this date, discovered in the prehistoric Koster site in Illinois, and found they were even older: around 10,100 years old.t been butchered for food. They had also been carefully buried, evidence they were valued by their owners. The Stilwell II dog, which probably resembled a small English settler, was under what seemed to be the floor of a living area. It is unclear why it took so long for tame dogs to arrive in the Americas, given that they were domesticated at least 14,000 years ago in Eurasia. By this time, people were already moving into North America from Siberia。t know if dogs were part of the first waves of immigration to the Americas says Luc Janssens of Ghent University in Belgium. It could be so, but no archaeological bones have yet been found. It is overwhelmingly probable that some of the early settlers did bring dogs to the Americas, but they may not have had the time or the spiritual pulsion to bury them, says Pat Shipman of Pennsylvania State University.（1）How old is the oldest known domestic dog in the Americas7 A.About 10,100 years.C.18,500 years.（2）The underlined word butchered in the fourth paragraph could be replaced by.

They had also been carefully buried, evidence they were valued by their owners. ”研究小組得出的結(jié)論是，這三種狗都是被馴化的，因為它們的骨骼是完整的，沒有皮膚的，所以沒有被宰殺作為食物。關(guān)鍵詞buried，可知劃線詞的意思是“殺死”，故選A。根據(jù)第二段中的“It is unclear why it took so long for tame dogs to arrive in the Americas, given that they were domesticated at least 14,000 years ago in Eurasia.”可知，對到達美洲的馴服的狗態(tài)度是不確定。（4）考查主旨大意。故選A。2．閱讀理解 Plants make a number of different structures that are specific for ant use.
