　Make a card about the size of a postcard and write two English letters L and R on it, L on the left and R on the right. First, hold the card about 80 cm away and you see both the letters. Then close your right eye and look at the letter R only with your left eye. And now, as you move the card slowly towards you, you'll find the letter L disappearing. But if you move the card nearer to your face, the letter will be seen again. Now do the same experiment with your left eye closed, you'll find the letter R disappearing.

Like most people, your intelligence（智力）changes from season to season. You are probably a lot sharper in spring than you are at any time of the year. A well known scientist, Ellsworth Huntington concluded（得出结论）from other men's work and his own that climate and temperature have a clear effect on people's intelligence.

He found that cool weather is much better for creative thinking than warm weather, but this doesn't mean that all people are not so quick at learning in summer as they are during the rest of the year. It doesn't mean, however, that the intelligence of a large number of people seems to the lowest in summer.

Spring season appears to be the best period of the year for thinking. One reason may be that in spring man's intelligence is affected（影响）by the same factors（因素）that bring about great changes in all nature.

Autumn is the next-best season, then follows winter. As for summer, it seems to be a good time to take long holidays from thinking.
