新視野大學(xué)英語(yǔ)視聽(tīng)說(shuō)教程第一冊(cè) Unit 4 Task 2: Mental Energy and Season

　　You may not believe that our mental energy varies from season to season. But some people think that it does. Research has shown that climate and temperature have a definite effect on our mental abilities. Scientists have discovered that cool weather is much more favorable for creative thinking than is summer heat. Spring spears to be the best period of the year for thinking. People seem to be a lot sharper in spring than they are in any other season. One reason may be that in spring people’s mental abilities are affected by the same factors that bring about great changes in nature. Fall is the next-best season, then sinter. Summer seems to be the best time to take a long vacation from thinking. This does not mean that all people are less intelligent in summer than they are during the rest of the year. It does mean, however, that the mental abilities of most people tend to be lowest in summer. Be aware of these facts, and you will bring your talent into full play.
