【正文】 he passage is closest in meaning to6. objective客觀的，目標，想到object物品，物體，所以A的unbiased沒有偏見的正確。原文說這兩個人對調查有興趣，調查是關于reflection在某些情況下怎么樣的。看下兩者的內容，之前說老師們benefit from reflection，后面說reflective practice幫助了老師，所以兩者的意思應該相同，也就是justify是正向詞，B定性C刺激D建議表明都是中性，所以都不對○supported○shaped○stimulated○suggested2. According to paragraph 1, it was believed that reflection could help teachers2. 以help teachers做關鍵詞定位至最后一句，幫助老師們智力上更多參與教學，所以答案是B。s hypothesis received additional support from the fact that the greatest diversity in Native American languages occurs along the west coast of the Americans, suggesting that this region has been settled the longest. More recent geologic studies documented deglaciation and the existence of icefree areas throughout major coastal areas of British Columbia, Canada, by 13,000 years ago. Research now indicates that sizable areas of southeastern Alaska along the inner continental shelf were not covered by ice toward the end of the last Ice Age. One study suggests that except for a 250mile coastal area between southwestern British Columbia and Washington State, the Northwest Coast of North America was largely free of ice by approximately 16,000 years ago. Vast areas along the coast may have been deglaciated beginning around 16,000 years ago, possibly providing a coastal corridor for the movement of plants, animals, and humans sometime between 13,000 and 14,000 years ago.The coastal hypothesis has gained increasing support in recent years because the remains of large land animals, such as caribou and brown bears, have been found in southeastern Alaska dating between 10,000 and 12,500 years ago. This is the time period in which most scientists formerly believed the area to be inhospitable for humans. It has been suggested that if the environment were capable of supporting breeding populations of bears, there would have been enough food resources to support humans. Fladmark and others believe that the first human colonization of America occurred by boat along the Northwest Coast during the very late Ice Age, possibly as early as 14,000 years ago. The coastal hypothesis suggests an economy based on marine mammal hunting, saltwater fishing gathering, and the use of watercraft. Because of the barrier of ice to the east, the Pacific Ocean to the west, and populated areas to the north, there may have been a greater impetus for people to move in a southerly direction.It has long been accepted that the Americas were colonized by a migration of peoples from Asia, slowly traveling across a land bridge called Beringia (now the Bering Strait between northeastern Asia and Alaska) during the last Ice Age. ■The first water craft theory about the migration was that around 11,00012,000 years ago there was an icefree corridor stretching from eastern Beringia to the areas of North America south of the great northern glaciers. It was the midcontinental corridor between two massive ice sheetsthe Laurentide to the westthat enabled the southward migration. ■But belief in this icefree corridor began to crumble when paleoecologist Glen MacDonald demonstrated that some of the most important radiocarbon dates used to support the existence of an icefree corridor were incorrect. ■He persuasively argued that such an icefree corridor did not exist until much later, when the continental ice began its final retreat. ■Paragraph 1: 1. The word justified in the passage is closest in meaning to 1. justify意思是證明……正當，支持，想到just有正義之意，所以A的support正確。C之后的he與前文過渡緊密；B的 but與之前過渡緊密Moreover, other evidence suggests that even if an icefree corridor did exist, it would have lacked the resources needed for human colonization.Where could the sentence best fit?14.

Evidence that an icefree corridor between two ice sheets developed when the continental ice first began to melt came primarily from radiocarbon dating.2. There is growing support for the theory that migration took place much earlier, by sea, following a coastal route along Alaska and down the northwest coast.3. Recent geologic evidence indicates that contrary to what had been believed, substantial areas along the coast were free of ice as early as 16,000 years ago.4. Research now indicates that the parts of the inner continental shelf that remained covered with ice were colonized by a variety of early human groups well adapted to living in extremely cold environments.5. There is evidence suggesting that areas along the coast may have contained enough food resources between 13,000 and 14,000 years ago to have made human colonization possible.6. Even though the northern part of the continent allowed for a more varied economy, several early human groups quickly moved south.Colonizing the Americas via the Northwest CoastIt has long been accepted that the Americas were colonized by a migration of peoples from Asia, slowly traveling across a land bridge called Beringia (now the Bering Strait between northeastern Asia and Alaska) during the last Ice Age. ■The first water craft theory about the migration was that around 11,00012,000 years ago there was an icefree corridor stretching from eastern Beringia to the areas of North America south of the great northern glaciers.
