Salvador Dali (1904-1989) was one of the most popular of modern artists. The Pompidou Centre in Paris is showing its respect and admiration for the artist and his powerful personality with an exhibition bringing together over 200 paintings, sculptures, drawings and more. Among the works and masterworks on exhibition the visitor will find the best pieces, most importantly The Persistence of Memory. There is also L'Enigme sans Fin from 1938, works on paper, objects, and projects for stage and screen and selected parts from television programmes reflecting the artist's showman qualities.

        The visitor will enter the World of Dali through an egg and is met with the beginning, the world of birth. The exhibition follows a path of time and subject with the visitor exiting through the brain.

        The exhibition shows how Dali draws the viewer between two infinities (无限). “From the infinity small to the infinity large, contraction and expansion coming in and out of focus: amazing Flemish accuracy and the showy Baroque of old painting that he used in his museum-theatre in Figueras,” explains the Pompidou Centre.

        The fine selection of the major works was done in close collaboration (合作)with the Museo Nacional Reina Sofia in Madrid, Spain, and with contributions from other institutions like the Salvador Dali Museum in St. Petersburg, Florida.

    People seem to have a natural need for friends and with good reason, friends increase your enjoyment of life and relieve feelings of loneliness. They even can help reduce stress and improve your health. Having good friends is especially helpful when you are going through any kind of hard time such as when you are experiencing anxiety, panic(恐慌) attacks, or depression.

    When you are with good friends, you feel good about yourself, and you are glad to be with them. A friends is someone who—

●you like, respect, and trust, and who likes, expects and trusts you, doesn't always understand you, but accepts and likes you as you are, even as you grow and change, allows you the space to change, grow, make decisions, and even make mistakes.

●listens to you and shares with you both the good times and the bad times.

●respects your need for secrets, so you can tell them anything.

●lets you freely express your feelings and emotions without judging, laughing at or criticizing you.

●accepts the limitations you have put on yourself and helps you to remove them.

    A person once said. "Friendship is a continuing source of bonding(连接),releasing, and creating in yourself and with the other person, there is an emotional bond between the two people."

    A good friend or supporter may or may not be the same age or the same sex as you, and may not have the same educational, cultural, or religious background, or share interests that are similar to yours. Friendships also have different depths(深度). Some are closer to the heart and some more superficial, but they're all useful and good.

    Studying abroad will shape you in various ways. You will learn things you never would have if you had stayed home. When you are young and unattached, you should travel. Besides, you just might save a large sum of money. College is expensive in the United States. It's cheap or free in other countries even for foreigners, so why not get out of here and come back smarter?

    More and more American students are currently studying at German colleges. That number has increased 20% over the last three years. Living costs are about $7,000 a year, which is even lower than in other European countries. Germany encourages international students. They create a multicultural landscape that benefits German students as well. According to a new report, Germany is home to six of the world's 100 best universities. These schools offer around 900 degrees completely in English and many German students speak the language.

    You could be part of Finland's excellent education system. The Finns charge no tuition and offer a number of courses purely in English. They would be happy for you to add flavor to their school scene. Cost of living there is high. Be prepared for frosty winters that far north, but you will get that sweet midnight sun in the summer.

    Many other European nations offer cheap or free college for foreign students, but if South America is more your thing, try Brazil. Most of the education will take place in Portuguese, so if that is in your plan you can study near beautiful beaches and jungles. The University of Sao Paulo and the State University of Campinas are both highly ranked internationally. Your money will go a long way there, too.

    Many of the lessons you will learn will be outside the classroom. Living on the economy in a foreign country will keep you on your toes. You will learn new customs, how to bargain, stay safe, budget and become more flexible with people. There is no better way to learn a language than by immersing yourself in it. At first, it will be the toughest thing you have ever done. Eventually, it will become second nature.

    Are you sometimes a little tired and sleepy in the early afternoon? Many people feel this way after lunch. They may think that eating lunch is the cause of the sleepiness. Or, in summer, they may think it is the heat. However, the real reason lies inside their bodies. At that time—about eight hours after you wake up—your body temperature goes down. This is what makes you slow down and feel sleepy. Scientists have tested sleep habits in experiments where there was no night or day. The people in these experiments almost always followed a similar sleeping pattern. They slept for one long period and then for one short period about eight hours later.

    In many parts of the world, people take naps (小睡) in the middle of the day. This is especially true in warmer climates, where the heat makes work difficult in the early afternoon. Researchers are now saying that naps are good for everyone in any climate. A daily nap gives one a more rested body and mind and therefore is good for health in general. In countries where naps are traditional, people often suffer less from problems such as heart disease. Many working people, unfortunately, have no time to take naps. Though doctors may advise taking naps, employers don't follow it! If you do have the chance, however, here are a few tips about making the most of your nap. Remember that the best time to take a nap is about eight hours after you get up. A short sleep too late in the day may only make you feel more tired and sleepy afterward. This can also happen if you sleep for too long. If you do not have enough time, try a short nap—even ten minutes of sleep can be helpful.

    Sweet potato plants don't have spines or poisons to defend themselves. But some have evolved a clever way to let hungry herbivores (食草动物) know they aren't an all-you-can-eat buffet, a new study finds. When one leaf injured, it produces a chemical that warms the rest of the plant and its neighbors to make themselves inedible (不宜食用的)to bugs. Sweet potato breeders could potentially engineer plants to produce the chemical as an all-natural pest defense.

    Plant ecologists led by Axel Mithofer of the Max Planck Institute for Chemical Ecology in Jena, Germany, started to look into sweet potato (Ipomoea batatas) defenses after they noticed something interesting about two varieties of the plant grown in Taiwan: The yellow-skinned, yellow-fleshed Tainong 57 is generally herbivore-resistant, but its darker orange cousin, Tainong 66, is plagued (造成麻烦) by insect pests.

    To find out why, the team offered up Tainong 57 and 66 plants to hungry African cotton leafworm caterpillars (毛虫).Both plants released at least 40 airborne compounds as the caterpillars snacked on their leaves. But Tainong 57 produced a lot more of a chemical called DMNT, which has a very distinct smell, the team details this month in Scientific Reports. ("The smell is not nice," Mithofer says. "You wouldn't want it as a perfume.")

    DMNT isn't a new compound; researchers have isolated (分离出) the smelly chemical from other plants such as corn and cabbage, and it is known to induce defense responses in some species.

    To determine whether this was happening in sweet potatoes, scientists set up two experiments. First, they put two plants next to each other and wounded one so it produced DMNT. Then, they exposed healthy Tainong 57 plants to DMNT they had synthesized (合成).In both cases, the DMNT caused the exposed plants to produce more of a protein called sporamin in their leaves. (Tainong 66 did not have the same reaction.) When the caterpillar's snack on sporamin, "they immediately stop eating because they don't feel well," Mithofer says.

    Sporamin is the main protein in sweet potato tubers (块茎),and is indigestible raw, which is why sweet potatoes must be cooked for humans to enjoy them. "If the caterpillars could cook it, they could eat it," Mithofer says. Theoretically, he says, sweet potato breeders could use genetic engineering to make different varieties of sweet potato produce as much DMNT as Tainong 57, and display the same defense responses.

    Still, the research isn't ready for prime time, cautions plant ecologist Martin Heil. DMNT might work in the lab, but in the field, airborne chemicals can be "blown away in seconds," says Heil, who studies plant-insect interactions at the National Polytechnic Institute in Irapuato, Mexico.

    Mithofer himself has no plans now to create genetically engineered sweet potato plants, because they would not be a viable (能活下去的) crop in Europe, where genetically modified crops are outlawed. So for now, Tainong 66 will have to put up with being a caterpillar salad bar.

Elizabeth Bishop is considered one of the best American poets of the 20th century. She was born in Worcester, Massachusetts in 1911. Her dad died when she was just a baby and her mom never recovered from the loss; she went to live with her grandparents in Nova Scotia, Canada when she was five. Eventually Bishop attended Vassar College, where she began to write poetry.

At Vassar she discovered Marianne Moore's poetry and met "Ms. Moore" and began their life-long friendship. She later met poet Robert Lowell. She wrote tons and tons of letters to both of them, which is good for us because we would otherwise know very little of her personal life. Bishop's poetry is sometimes considered objective and cold because it shows almost nothing about the poet or her life.

Bishop published her first book of poetry in 1946 and wrote until her death in 1979. She would spend years working on a single poem. Her poems are not the result of hasty scribbling (匆忙乱写) on paper while eating breakfast. Over a lifetime of writing, she only published about 275 pages of poetry, and about 40 of those are translations. She would look through drafts of poems again and again and improve them until they were as close to perfect as she could get them.

Reading Elizabeth Bishop is like being transported to the very place, the very moment she's writing about. She leads us to a microscope so we can see every smallest part of the scene. It seems she's always asking us to notice more, and more until the poem is so clear in our minds that it's almost painful — like a light that's too bright. It might take your eyes a while to get used to it, but once they do, you'll like what you see.
