An inherent problem in an experiment of this nature is finding volunteers who will agree to be brained with a beer bottle in the name of science. The scientists overcame this obstacle by dropping steel balls onto full and empty beer bottles. They found that the empties were stronger than their full brethren because the gas pressure from the liquid produces additional strain on the glass.
Needless to say, full or not, beer bottles can cause a whole lot of hurt, which is why the
A. How will the public take the experiment
B. Does it have great potential for application
C. Where can we find enough panda waste

[单项选择]In the dark night of the desert, a group of US Air Force scientists is testing a new device for a missile to target. Designed to seek out the heat of an enemy aircraft engine, it is now going through its paces by tracing the movement of a flashlight waving thirty feet away in the darkness. A hundred yards away, unseen by the man, a rattlesnake sliding between the stones senses a patch of warmth. Although the snake’s mechanism is small enough to be packed into a head the size of a nut, it can detect a change in temperature of one-thousandth of a degree. With a sound the snake closes in and strikes for the kill.
Whenever we look in the animal world we find the same story. Almost anything that man can do, nature has already done better. So, it is for the purpose of learning from nature that a new science called bionics has grown up. Its aim is to find out how animal’s instruments work so that man can copy them for his own purpose.
Imagine being able to know a friend several mile
A. show the deadliness of the missile.
B. demonstrate what bionics is.
C. show that man is wiser than nature.
D. demonstrate that a rattlesnake is dangerous.

Through the years, our view of what leadership is and who can exercise it has changed considerably. Leadership competencies have remained constant, but our understanding of what it is, how it works, and the ways in which people learn to apply it has shifted. We do have the beginnings of a general theory of leadership, from history and social research and above all from the thoughts of reflective practitioners such as Moses, Julius Caesar, and James Madison, and in our own time from such disparate sources of wisdom as Gandhi, Winston Churchill, Mao Tse-tung, and Henry Kissinger, who have very little in common except that they have not only been there but tried with some fairness to speculate on paper about it.
But tales and reflective observation are not enough except to convince us that leaders are physically strong and abnormally hard workers. Today we are a little closer to understanding how- and who people lead, but it wasn’t easy getting there. Decades of academ
