The saying that practice makes perfect mean that after you have plenty of practice in what you were doing，you will be perfect in it．If you want improve your study and work，remembering that the most important thing is how to put the knowledge you have learned into practice．For example，when learning a language，though you can make full use for your talent，practice is necessary．If you only learn grammar rules by the heart and don’t do enough exercise，it’s certain that you can’t understand the language perfectly．But if you real practise a lot，maybe you will understand them much better．In this way，you can apply that you have learned better．

【题目】B

American researchers found females are the more talkative sex because of a special “language protein(蛋白质)” in the brain.

The study, conducted by neuroscientists (神经学家)and psychologist from the University of Maryland, concluded that women talked more because they had more of the Foxp2 protein. The research, published in the Journal of Neuroscience, found that higher levels were found among humans that were women but in rats that were males. Their findings came after it was previously claimed that ladies speak about 20,000 words a day – over 13,000 more than men. “This study is one of the first to report a sex difference in the expression of a language-associated protein in humans or animals,” said Prof Margaret McCarthy, who led the study. In their study, the researchers attempted to determine what might make male rats more vocal than their female friends.

They separated four-day-old rats from their mothers and then counted the number of times they cried out in the “ultrasonic range”, the frequencies higher than humans can hear, over five minutes. While both sexes called out hundreds of cries, the males called out twice as often, they found. But when the pups were returned to their mother’s cage, she fussed over her sons first. Tests conducted on the parts of the brain known to be associated with vocalcalls showed the male pups have up to twice as much Foxp2 protein as the females. The researchers then increased the production in the brains of female pups and reduced it in males. This led to the female rats crying out more often and their mothers showing more interest to them. In contrast, males became less “talkative”.

The researchers then tested samples from ten children, aged between three and five, which showed that females had up to 30 per cent more of the Foxp2 protein than males, in a brain area key to language in humans.

“Based on our observations, we assume higher levels of Foxp2 in girls and higher levels of Foxp2 in male rats is an indication that Foxp2 protein levels are associated with the more communicative sex,” said Prof McCarthy. “Our results imply Foxp2 as a component of the neurobiological basis of sex differences in vocal communication in mammals. “
