题目:

由于一种新的电池技术装置的出现,手机在几分钟内充满电很快就会变成现实。这种新装置是一种超级电容器,它储存电流的方式是通过让带电离子聚集到多孔材料表面,而非像传统电池那样通过化学反应储存这些离子。因此这种超级电容器能在几分钟内储满电。研究人员认为这种技术装置将会替代传统电池。  以下哪项如果为真,不能支持上述结论( )

A.超级电容器能够储存大量电能,保证长时间正常运行

B.超级电容器能循环使用数百万次,相比之下传统电池只能使用数千次

C.超级电容器可嵌入汽车底盘为汽车提供动力,可更方便地进行无线充电

D.超级电容器充电时所耗电能比传统电池少90%,但供电时间比后者长10倍

My friend Paul will never forget his chemical teacher.
He was a little man with thick glasses, and he had 
a strange way of making his classes live and interesting.
And his lessons were not easily forgotten.
Paul remembers one of his first lesson from his teacher.
After all the students were in a chemistry lab, the teacher brought 
out three bottles. One was full with petrol, one with castor oil and 
one with vinegar."Now watch carefully," said the teacher.
He filled a cup with some the petrol, some of the castor oil
and some of the vinegar. As the students watched him, he mixes the 
three together. After that, he held up one of his fingers and showed to the
class. He then dipped it into the cup and said" You must do everything as I do it."
