Ⅱ.阅读理解

People have been acting like people—in other words， they've been making tools，

creating ceremonies， and sharing food—for a long time. That's the conclusion of

a recent study from South Africa's southern coast.

There， in a cave lying above the sea， researchers from Arizona State University

have found evidence that humans were behaving in surprisingly complex ways as early

as 164,000 years ago. Our species， Homo sapiens， appeared an estimated 200,000

years ago.

The cave held three important clues about the behavior of these Stone Age people.

First， the researchers found the remains of all kinds of shellfish. The people

who lived in the cave probably collected these creatures from rocky shores and tide

pools and brought them to the cave to eat.

The researchers propose the early Africans moved to the South African coast

between 195,000 and 130,000 years ago. Around that time， the climate inland turned

relatively cold and dry. Therefore， there were fewer plants and animals to eat away

from the coast.

When these ancient people moved to the coast， they probably experienced a major

cultural shift， the researchers suspect. That's because observations of modern

hunter－gatherer societies suggest that men are more likely to hunt for big animals

when people live inland. On the coast， women play a more important role in providing

food by gathering plants and shellfish. As for the second clue， the researchers unearthed 57 pieces of reddish

pigment(颜料). The researchers think that the cave habitants used the paint for

coloring their bodies or for other ceremonies. Symbolic behavior is a clearly human

feature.

Finally， the search discovered over 1,800 stone tools， including well－crafted

blades(刀片). These blades came in various sizes. The smallest were just less than

a half－inch wide. Ancient people may have attached these blades to the end of a

stick to make spears or other tools.

16．What is the passage mainly about？

A．Ancient cave behavior.

B．New evidence of ancient life.

C．The history of human beings.

D．Human behavior's development.

17．The early Africans moved to the South African coast with the main purpose

of ________.

A．avoiding badly cold and dry weather

B．seeking the cultural development

C．seeking enough food to live on

D．living a newer and better life

18．According to the passage， the cave habitants________.

A．knew how to use colors for decoration

B．made a living largely by hunting animals

C．only could made tools with rough blades

D．could hunt for fish in the sea with ships

19．After the early Africans moved to the coast， what probably happened to their
