专八练习题：

Sporting activities are essentially modified forms of hunting behavior.

Viewing biologically, the modern footballer is revealed as a member of a disguised __1__

hunting pack. His killing weapon has turned into a harmless football

and his prey into a goal-mouth. If his aim is inaccurate and he scores a goal, __2__

enjoys the hunter’s triumph of killing his prey. __3__

To understand how this transformation has taken place we

must briefly look up at our ancient ancestors. They spent over a million __4__

year evolving as co-operative hunters. Their very survival depended on success __5__

in the hunting-field. Under this pressure their whole way of life, even if their __6__

bodies, became radically changed. They became chasers, runners, jumpers,

aimers, throwers and prey-killers. They co-operate as skillful male-group __7__

attackers.www.for68.com

Then, about ten thousand years ago, when this immensely long formative __8__

period of hunting for food, they became farmers. Their improved intelligence,

so vital to their old hunting life, were put to a new use—that of penning, __9__

controlling and domesticating their prey. The food was there on the farms,

参考答案及解析:

1. 将viewing改为viewed

非谓语动词view和句子的主语是逻辑动宾关系。

2 .将inaccurate改为accurate

如果真的目标不准确，也就不可能进球了（he scores a goal）。

3 .在enjoys前面加he

由于前面if his aim is accurate and he scores a goal 是条件状语从句，因此可见这里是主句，主句的主语he是不可以省略的。

4 .将look up at的up省略

5 .将year变为复数

6 .将if去掉

7 .将co-operate 改为co-operated

8 .将when改为after

9.将were改为was

该谓语动词的主语是Their improved intelligence，是单数。

10. 将farming改为hunting

纵观全文，在从事种植业后，“狩猎”而不是“农耕”的危险和不确定性对人们的生存已经不再那么重要了。
