We humans spend about one-third of our lives asleep. This may sound like a lot of time, but it is not wasted. Sleep not only helps us stay healthy but it also helps our brains remember. Our brains need good sleep to remember what we do and learn during the other two thirds of our lives when we are awake.
Researchers at the University of Wisconsin-Madison have found that sleep helps improve brain performance by shrinking(收缩)synapses in the brain. A synapse is the area where cells pass messages to other cells.
Scientist Chiara Cirelli is a leader at the school 's Center for Sleep and Consciousness. She told the reporter that sleep is when the human brain mixes information it has learned while awake into its general collection of knowledge. Meanwhile, the brain forgets unimportant details. This forgetting is important. It makes space for new learning and new memories.
Cirelli said that the Centers research began with this hypothesis(假设): We sleep so that our brain can repair and refresh itself, She said the idea seems simple and reasonable. However, testing and discovering how it works has been extremely difficult.
Synapses are only about 20-40 nanometers wide. The team began their study by measuring(测量) the size of the synapses to look for changes in these already tiny spaces between nerve cells. Cirelli says the process(过程) is difficult because \have to be done by hand.” The team had to wait until improvements in laboratory technology made it possible to see these tiny changes. A University of Wisconsin press release called the research a \” Many research specialists worked for four years to photograph, rebuild and study certain areas of a mouse brain. The report also said the scientists measured 6,920 synapses. Cirelli says they found that our synapses shrink as our brains clean themselves during sleep. We wake up refreshed and ready to fill those synapses with new information. The research findings are the result of years of hard work at the University of Wisconsin Madison. The researchers published their findings in the journal Science.

Best friend for a lifetime
The Year of the Dog will begin on Feb 16, according to the Chinese lunar calendar, Decorations about dogs will hang on doors or windows.
Dogs are man's best friend. 36 It means that dogs are loyal(忠实的), and will stay with their owners through thick and thin.
Although dogs are seen as family members today, China and Western countries have different cultural beliefs about dogs. In Chinese, some words concerning dogs have negative meanings, such as \s mouth.\day\
38 Perhaps the most touching example is from the 8th century BC, in Greek poet Homer's The Odyssey. When Greek hero Odysseus finally returns home after 20 years away at war, only one person-sorry, animal- recognizes him; his dog, Argos, Argos is an old, sick dog, and is about to die; he is overjoyed to see his owner again after so many years.
39 For example, Dutch artist Breughel's painting The Hunters in the Snow(1565) first shows a detail of hunting dogs following closely behind hunters as they return from the hunt to their snow-covered farm.
Actually, people were close to dogs in a way that they weren't close to cows, pigs or even horses. Farmers worked closely with dogs. Even after science came to agriculture and dogs lost their traditional roles, the close relationship between man and dogs remained.
Nowadays in the West, a great many people keep dogs as family members. People feed them, and takes them on holidays, etc. 40 This loyalty is the beginning of the English saying, “A dog is man’ s best friend.”
A. In later centuries, the friendship between humans and dogs was a common subject for artists. B. Dogs are thought to be cute and lovely animals.
C. This shows the attitude toward dogs that many people around the world share. D. Therefore, a deep feeling has been developed day by day.
E. The dog-human relationship goes right back to the beginnings of Western civilization. F. In return, dogs are loyal in a way that friends sometimes aren't. G. But in English, the situation is different.
