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(最初的) crossing were probably following the animals they used for food. Eventually, 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. _小题1:__

For the next few thousand years, the First Americans migrated（迁徙） 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. __小题2:__In the far north, above the Arctic Circle, the First Americans became hunters of the ocean.  __小题3:__ In the brief summer，they gathered berries and other plants.

They began by living in caves that already existed in the cliffs.__小题4:__ The dwellings(住处) they constructed in many ways resembled today's apartment buildings.__小题5:__ They built a system of dams and canals so they could store and use water almost any time of the year.
