A strong memory depends on the health and vitality （活力） of your brain. They say that you can't teach an old dog new tricks, but when it comes to the brain, scientists have discovered that this old saying simply isn't true. {#blank#}1{#/blank#}

      Give your brain a workout. Memory, like muscular strength, requires you to “use it or lose it”. The more you work out your brain, the better you'll be able to process and remember information.{#blank#}2{#/blank#}

        Don't skip the physical exercise. While mental exercise is important forbrain health, that doesn't mean you never need to break a sweat. Physical exercise helps your brainstay sharp. It increases oxygen to your brain and reduces the risk for disorders that lead to memory loss.

        Get enough sleep. There is a big difference between the amount of sleep you can get by on and the amount you need to function at your best.{#blank#}3{#/blank#}Keep stress in check. Stress is one of the brain's worst enemies. Over time, stress destroys braincells. Studies have also linked stress to memory loss.

        Have a laugh.{#blank#}4{#/blank#} That holds true for the brain and the memory, as well as the body. Unlike emotional responses, which are limited to specificareas of the brain, laughter engages multiple regions across the whole brain.

{#blank#}5{#/blank#}Just as the body needs fuel, so does the brain. You probably already know that a diet based on fruits, vegetables, whole grains, “healthy”fats and lean protein will provide lots of health benefits, but such a diet can also improve memory. For brain health, though, it's not just what you eat—it's also what you don't eat.

A. Eat a brain-boosting diet.

B. Play games with memory.

C. Laughter is the best medicine.

D. But oversleeping is not good for yourbrain.

E. Even skipping a few hours makes adifference!

F. You have to shake things up from timeto time!

G. The human brain has an astonishingability to adapt and change.

    Franz Boas was born in Minden, Germany, in 1858. After studying at the Universities of Heidelberg, Bonn, and Kiel, he received a doctor's degree in physics from the University of Kiel in 1881. His first fieldwork experience was among the Eskimo in Baffinland, Canada, in 1883-1884. In 1886, on his way back from a visit to the Kwakiutl Indians of British Columbia, Canada, he stopped in New York and decided to settle.

    Boas's first teaching position in America was at the newly founded Clark University in 1888. Eleven years later, he became professor of anthropology(人类学) at Columbia University. From 1896 to 1905 he was also curator(馆长) of anthropology at the American Museum of Natural History in NY. There he organized and took part in the Jesup North Pacific Expedition of 1902, which suggested the possibility of a strong relationship between northern Asian and northwestern Native American cultures. After guiding the Columbia Anthropology Department for 41 years, Boas became Professor Emeritus(荣誉退休教授) in 1937.

    Boas's anthropological studies have become classics in the field. He showed the necessity of studying a culture in all its aspects, including art, history, dance, language as well as the characteristics of the people. He pointed out that the differences in peoples were the results of historical, social and geographic conditions and all populations had complete and equally developed culture. He argued that no truly pure race exists, and that no race is superior to any other.

    In 1911 Boas published the Mind of Primitive Man, a series of lectures on culture and race. In the 1930s the Nazis in Germany burned the book. Boas revised the book in 1937 and put his anthropological ideas about racism into popular magazine articles. In 1942, Boas died, having founded anthropology as a recognized social science.

    Theater is one of the oldest and most important art forms in world culture, it is also one of the richest art forms. Many people work together to bring a play to life. There are playwrights, directors, set designers, costumers, lighting technicians, and, of course, actors. If the performance is a musical, the skills of a songwriter, a choreographer, and musicians are also required. The excitement of opening night can be felt by the people waiting to watch a performance and by the performers and workers backstage waiting for the curtain to go up. Live theater is thrilling because no one really knows how well the play will go until it is performed.

    The word theater comes from the Greek theatron, which means "a place for seeing." One concept from Greek theater that is still seen in some plays today is the "Greek Chorus". This consists of several actors or characters watching the action of the play(almost like the audience) and then commenting on what whey just saw with either reactions or dialogue.

Although most people think of the theater in terms of a play performed on the stage, theater has taken on a much broader meaning in the modern world. You may find yourself walking into a theater with no seats in the rows. Instead, you are seated among the set pieces, which makes you part of the setting. Sometimes theater may come to life on a street corner, or in a classroom. The excitement of theater is in its very nature—-it is an art form that changes as it is interpreted(诠释) in different ways by different people. That is probably why the works of the greatest playwright of all time, William Shakespeare, are still performed and enjoyed today, both in classic and new interpretations.

    What makes a building ugly? Everyone's got their own opinion, so it's hard to say. Now, let's take a look at some of the world's worst buildings.

    The Torre Velasca

    The Torre Velasca in Milan is in the centre of Milan(Italy). The tower, which went up in the 1950s, is about 100 metres tall. Its design is actually a modern representation(代表) of a traditional Lombard castle, where the lower parts were narrower than the upper parts.

    The Mirador Building

    The Mirador Building in Madrid(Spain)was created by Dutch studio MVRDV and the Spanish architect(建筑师)Blanca Lleó.The building, which is a block of flats, opened in 2005. There is a large rectangular(矩形的)hole in the upper part of it, which is used by the neighbourhood as a meeting area and playground.

    The Prague TV Tower

    The Prague TV Tower is in Prague(the capital of the Czech Republic). It stands 216 metres high and looks a bit like a tall, thin space ship. Prague is famous for its architectural beauty, so when the tower was put up in 1985 by architect Vaclav Aulicky and engineer Jiri Kozak, many felt it didn't fit in.

    The Longaberger Basket Company

    The Longaberger Basket Company building is in Newark, Ohio(USA). The office block was opened in 1997 and looks like a very large basket. It's got seven floors and two handles(把手)at the top. The handles weigh about 150 tons. It may not be the ugliest building in the world but it's certainly one of the most unusual.
