Scientists have proved that sleeping and learning go hand in hand. Even a short nap can boost our memory and sharpen our thinking. But the relationship goes deeper than that. "The brain is not passive while you sleep," scientist Anat Arzi said. "It's quite active. You can do many things while you are asleep." Arzi and her coworkers didn't try to teach the sleeping volunteers any complex information, like new words or facts. Instead, the scientists taught volunteers to make new connections between smells and sounds. When we smell something good, like a flower, we take deep breaths. When we smell something bad, we take short breaths. Arzi and her co-workers based their experiment on these reactions. Once the volunteers fell asleep in the lab, the scientists went to work. They gave them a whiff of something pleasant and meanwhile played a particular musical note. They didn't wake up, but they heard--and sniffed deeply. Then the scientists gave the volunteers a whiff of something terrible and played a different musical note. Again, the volunteers heard and smelled--a short snort this time--but didn't wake up. The researchers repeated the experiment. After just four repetitions, volunteers made a connection between the musical notes and their paired smells. When the scientists played the musical tone that went with good smells, the sleepers breathed deeply. And when the scientists played the musical tone that went with bad smells, the sleepers breathed briefly--despite there being no bad smell. The next day, the volunteers woke up with the sound-smell connection. They breathed deeply when hearing one tone and cut their breaths short when hearing the other, which must have been unusual for them. Imagine walking down the street and taking a deep breath upon hearing a particular sound! The passage mainly tell us _ A) special smells and sounds can improve our memory. B) our brain can actually learn something new during the sleep. C) the volunteers will always hear similar sounds in the street. D) our brain can tell the difference between smells during the sleep.

The history of modern art begins with Impressionism, a movement started in Paris in the mid-1800's. At that time many artists painted in a very traditional way that involved spending hours in a studio,painstakingly creating paintings that were extremely detailed. These paintings were sometimes of people or landscapes or historical events. In 1863, Edouard Manet exhibited his painting "Dejeuner sur l'erbe" at the Salon des Refuses. The painting caused acommotion , thus starting the Impressionist movement. Although Edouard Manet is the declared leader and founder of the group, he was not present at the first group exhibition or any of the other eight collective Impressionist shows. The movement gained more attention in the April of 1874 when Claude Monet, Auguste Renoir, Alfred Sisley, and Jean-Frederic Bazille formed Society of Artists, Painters, Sculptors, Engravers and began exhibiting outside of the official salon. The same year, the term Impressionism was invented by criticizing journalist Louis Leroy to describe their paintings, who worked for the magazineLe Charivari. The Impressionists often paint out of doors and want to show how light and shadow fall on objects at particular times of the day. Their works are sometimes described as "captured moments" and are characterized by short quickbrushstrokes of colour which, when viewed up close looks quite messy and unreal. If we step back from the Impressionist paintings, the colours are blended together by our eyes and we are able to see the painters' subjects which often show colourful landscapes, sunlight on water as well as people busy with outdoor activities. The works of the Impressionists are best viewed _ . A) with imagination B) at a distance C) outdoors D) in a studio
