We are living in what we call the second great change in the state of
man. The first is the change from pre-civilized to civilized societies. The
first five hundred thousand years or so of man’s existence on the earth were
relatively eventful. (1)______
Comparing with his present condition, he puttered along in an astonish- (2)______
ingly stationery state. There may have been changes in language and culture (3)______
which are not reflected in artifacts, but if there were, these changes are lost for us. (4)______
The evidence of the artifacts, therefore, is conclusive. Whatever chang- (5)______
es they were, they were almost unbelievably slow. About ten thousand
years ago, we begin to perceive an acceleration in the rate of changes.
This becomes very noticeable five thousand years ago as the develop- (6)______
ment of the first civilization. The details of this first great change are
probably past our recovery. However, we do know that it depended on two (7)______
phenomena: the development of agriculture and the development of exploita
tion. Agriculture, which is the domestication of crops and livestocks and the (8)______
plantation of crops in fields, gave man a secure surplus of food from the (9)______
food producer. In a hunting and fishing economy it seems to take the food
producer all his time to produce enough food for himself and his family. The
moment we have agriculture, with its superior production of this form of (10)______
employment of human resources, the food producer can produce more food
than he and his family can eat. [br] (5)
选项
答案
therefore — however
解析
“The evidence of the artifacts…”这句话和上句应该是转折关系: “尽管这些变化我们无从知晓,但这些人造制品却留下了确凿的证据。”因此应换therefore为however或意思相近的连词。
