Why would human beings waste a third of their lives sleeping when they could be doing more important things like looking after their families or working? Some scientists believe sleeping helps recharge the body, while others think it is important for strengthening newly-formed memories. Now, there is new evidence which suggests that the purpose of sleep may be to forget some of the millions of new things we learn each day.
The neurons in the human brain consist of fibers called dendrites(树突). These grow as we learn new things and connect the brain’s cells to each other at contact points called synapses(突触). The larger the dendrites become and the more cells they connect, the more information we store.
In 2018, Giulio Tononi and Chiara Cirelli, both biologists at the University of Wisconsin-Madison, suggested a new idea: The things our brains learn each day result in so many synapses that things start to get a little messy. Sleeping allows us to sort through(整理) the “noise” and dispense all the unnecessary information, leaving behind only the most important memories.
Recently, the university’s research has provided direct evidence to support the theory. The experiment involved analyzing 6,920 synapses in the brain shavings from two groups of mice over a four-year period; one group had been allowed to sleep, while the other had been kept awake and entertained with toys. The researchers discovered that the brain shavings of the sleeping mice had nearly 20 percent fewer synapses than those that had been kept awake and entertained.
It was also evident during the study that the brain does not shave every synapse. 20% of neurons remained unchanged; these were most likely well-established memories. Therefore, although we may be sleeping to forget some of what we’ve learned, the brain “forgets”in a smart way.
Most researchers believe clearing our brains is not the only purpose of sleep. Resting our minds and bodies has also been found to help with other biological functions like strengthening our immunity. Though scientists may never agree on a single reason, they are all sure of one thing－a good night’s rest is essential for our health. So try and spend at least a third of your day sleeping!

Americans have always been ambivalent in their attitudes toward education. On the one hand, free and universal public education was seen as necessary in a democracy, for how else would citizens learn how to govern themselves in a responsible way? On the other hand, America was always a country that offered financial opportunities for which education was not needed: on the road from rags to riches, schooling-beyond the basics of reading, writing, and arithmetic-was an unnecessary detour.
Even today, it is still possible for people to achieve financial success without much education, but the number of situations in which this is possible is decreasing. In today's more complex world, the opportunities for financial success is closely related to the need for education, especially higher education.
Our society is rapidly becoming one whose chief product is information, and dealing with this information requires more and more specialized education. In other words, we grow up learning more and more about fewer and fewer subjects.
In the future, this trend is likely to continue. Tomorrow's world will be even more complex than today's world, and, to manage this complexity, even more specialized education will be needed.
