The First Americans
There was a time long ago when a land bridge connected Asia and North America. The first settlers in North America crossed this land bridge from what is now Siberia to Alaska. The people who made this initial crossing were probably following the animals they used for food.
Finally, the oceans rose and the land bridge between the continents disappeared. The settlers, who I shall call the “First Americans”， could not return to their homeland.
For the next few thousand years, the First Americans moved south and east throughout North and South America. They made the journey all the way from Alaska to the southern tip of South America, a distance of more than 10,000 miles.
In the far north, above the Arctic Circle, the First Americans became hunters of the ocean.In the summer, they gathered berries and other plants. In the winter, they stayed in lodges much of the time preparing for the next summer. It was a hard life, but they learned to survive in these terrible conditions.
Farther south, in what is now Arizona, Utah, Colorado, and New Mexico, the First Americans became cliff dwellers. They began by living in caves that already existed in the cliffs.The dwellings they built in many ways resembled today's apartment buildings.
They built a system of dams and canals so they could store and use water almost any time of the year. They were so successful that they could raise fruits and vegetables that were not found naturally in the desert.
A．They also discovered foods like corn and potatoes.
B．Along the way, they established many different civilizations.
C．They discovered how to add to the caves by building structures of wood and stone.
D．People living near each other tended to share similar environments and customs.
E．They built boats of animal skins and hunted or fished for their food.
F．They would have to survive in the New World they had discovered.
G．The First Americans of the Southwest learned to water the desert.

Answer 1

【答案】F；B；E；C；G
【解析】本文是一篇記敘文，講述了最早的美洲人通過大陸橋到達了北美，然而當海平面上升后，大陸橋被淹沒，他們只好呆在美洲，再也回不到家鄉(xiāng)了，于是他們就慢慢地朝南朝東拓展遷徙，在此過程中，有些人學會了灌溉，有些人學會了狩獵，于是各種文明應運而生了。
（1）考查對上下文的理解和推理判斷能力。根據(jù)空前”The settlers, who I shall call the ‘First Americans’， could not return to their homeland.說明他們無法回去了，那么不得不在這個新的世界幸存下來，故F項符合上下文。
（2）考查對上下文的理解和推理判斷能力。根據(jù)空前“They made the journey all the way from Alaska to the southern tip of South America, a distance of more than 10,000 miles.”說明他們一直在遷移，在遷移的途中，建立了多種文明，故B項符合上下文。
（3）考查對上下文的理解和推理判斷能力。根據(jù)空前“In the far north, above the Arctic Circle, the First Americans became hunters of the ocean”說明他們求生的方法就是捕獵，故E項符合上下文。
（4）考查對上下文的理解和推理判斷能力。根據(jù)空前“They began by living in caves that already existed in the cliffs.”說明是指他們生活的方式也方式了變化，故C項符合上下文。
（5）考查對上下文的理解和推理判斷能力。根據(jù)空后“They built a system of dams and canals so they could store and use water almost any time of the year.”說明他們學會了如何管理水源，故G項符合上下文。
