Every animal sleeps, but the reason for this has remained foggy. When lab rats are not allowed to sleep, they die within a month. 1.
One idea is that sleep helps us strengthen new memories. 2. We know that, while awake, fresh memories are recorded by reinforcing (加强) connections between brain cells, but the memory processes that take place while we sleep have been unclear.
Support is growing for a theory that sleep evolved so that connections between neurons(神经元) in the brain can be weakened overnight, making room for fresh memories to form the next day. 3.
Now we have the most direct evidence yet that he is right. 4.The synapses in the mice taken at the end of a period of sleep were 18 per cent smaller than those taken before sleep, showing that the connections between neurons weaken while sleeping.
If Tononi’s theory is right, it would explain why, when we miss a night’s, we find it harder the next day to concentrate and learn new information — our brains may have smaller room for new experiences.
Their research also suggests how we may build lasting memories over time even though the synapses become thinner. The team discovered that some synapses seem to be protected and stayed the same size. 5. “You keep what matters,” Tononi says.
A. We should also try to sleep well the night before.
B. It’s as if the brain is preserving its most important memories.
C. Similarly, when people go for a few days without sleeping, they get sick.
D. The processes take place to stop our brains becoming loaded with memories.
E. That’s why students do better in tests if they get a chance to sleep after learning.
F. “Sleep is the price we pay for learning,” says Giulio Tononi, who developed the idea.
G. Tononi’s team measured the size of these connections, or synapses, in the brains of 12 mice.

All around the world, people drink tea. But tea does not mean the same thing to everyone. In different countries people have very different ideas about drinking tea.
In China, for example, tea is always served when people get together. The Chinese drink it at any time of the day at homes or in teahouses. They prefer their tea plain with nothing else in it. Tea is also important in Japan. The Japanese have a special way of serving tea called a tea ceremony. It is very old and full of meaning. Everything must be done in a special way in the ceremony. There is even a special room for it in Japanese homes.
Another tea drinking country is England. In England, the late afternoon is “teatime”. Almost everyone has a cup of tea then. The English usually make tea in teapot and drink it with cream and sugar. They also eat cakes, cookies and little sandwiches at teatime.
In the United States people drink tea mostly for breakfast or after meals. Americans usually use tea bags to make their tea. Tea bags are faster and easier than making tea in teapots. In summer, many Americans drink cold tea --- “iced tea”. Sometimes they drink iced tea from cans, like soda.
