[单项选择]The healing power of maggots is not new. Human beings have discovered it several times. The Maya are said to have used maggots for therapeutic purposes a thousand years ago. As early as the sixteenth century, European doctors noticed that soldiers with maggot-infested wounds healed well. More recently, doctors have realized that maggots can be cheaper and more effective than drugs in some respects, and these squirming larvae have, at times, enjoyed a quiet medical renaissance.

[单项选择]All her life, my mother wanted busy children. It was very important that her house should remain at all times clean and tidy.
You could turn your back for a moment in my mother’s house, leave a half written letter on the dining table, a magazine open on the chair, and turn around to find that my mother had "put it back where it belonged," as she explained. My wife, on one of her first visits to my mother’s house, placed a packet of biscuits on an end table and went to the kitchen to fetch a drink. When she returned, she found the packet had been removed. Confused, she set down her drink and went back to the kitchen for more biscuits, only to return to find that her drink had disappeared. Up to then she had guessed that everyone in my family held onto their drinks so as not to make water rings on the end tables. Now she knows better.

How efficient is our system of criminal trial Does it really do the basic job we ask of it—convicting the guilty and acquitting the innocent It is often said that the British trail system is more like a game than a serious attempt to do justice. The lawyers on each side are so engrossed in playing hard to win, challenging each other and the judge on technical points, that the object of finding out the truth is almost forgotten. All the effort is concentrated on the big day, on the dramatic cross examination of the key witnesses in front of the jury. Critics like to compare our "adversarial" system (resembling two adversaries engaged in a con test) with the continental "inquisitorial" system, under which the judge plays a more important inquiring role.
In early times, in the Middle Ages, the systems of trial across Europe were similar. At that time trial by "ordeal" —especially a religious event—was the main way of testing gu
