     Chocolate lovers know that eating chocolate can give them a feeling of happiness. Now it is known too

that eating chocolate may also make people cleverer.

     Dr. Bryan Raudenbush recently made a study to see if eating chocolate can make people cleverer. The

U. S. scientist knew that chocolate had several stimulants (兴奋剂). But he was not sure how these stimulants

did their job and thus made people clever.

     To find out, Dr. Raudenbush gave the first group of people 85g of milk chocolate to eat and the second

group ate no chocolate at all. After 15 minutes, he tested their memory, and he also tried to see if they were

able to deal with problems right.

     The first group had higher scores. They were able to remember more words and pictures than the second

group, and they could solve (解决) problems much faster. Dr. Raudenbush then decided that the stimulants

in chocolate could make people do things faster and better. And he suggested that if people wanted to do a

better job, eating chocolate from time to time may be of help.

     Of course eating chocolate can't make sure that you can study well without hard work. You'll still need

to study hard to get good results.
