Salvador Dali (1904-1989) was one of the most popular 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.

    School is more than a place where students learn subjects such as math, science and reading.{#blank#}1{#/blank#} While the focus of school is not to make a student socially popular, learning these skills is an important part of education. You may have personal issues when it comes to making friends in class, but with coaching you will be well on your way to climbing the social ladder. Here are some instructions.

    Partner with classmates. Use projects as a reason to partner with people you would like to become friends with in your class.{#blank#}2{#/blank#} Be reliable when partnering on a project so that you carry your own weight and put your best foot forward.

    {#blank#}3{#/blank#}There are many lulls (间歇) during class that will afford you an opportunity to engage a classmate. Giving a compliment to a person without overdoing it will help you come off friendly without looking desperate. Icebreakers can be as simple as saying hello or talking about the weather or class work.

    Get involved in activities. Offer to join a study group or get involved in other school activities to meet up with potential friends.{#blank#}4{#/blank#}

Share your knowledge with others. Helping others you wan! to befriend to understand a concept is a great way to avoid disrupting the class and to make contact.

    {#blank#}5{#/blank#}Send others positive signals such as smiling or waving so that you seem friendly.

A. Break the ice without disturbing the class.

B. Take an active approach to making friends.

C. Ask for help from students you want to befriend.

D. Join available school programs that you are interested in.

E. Assignments will give you an excuse to communicate if you are shy.

F. It is also an environment that teaches and tests social communication.

G. This can be pleasing as well as a great way to interact with parents.

Having Breakfast or Not

    Will it matter if you don't take your breakfast? A short time ago, a test (试验) was given in the United States. People of different ages, from 12 to 83, were asked to have a test. During the test, these people were given all kinds of breakfast, and sometimes they got no breakfast at all. Scientists (科学家) wanted to see how well their bodies worked when they had eaten different kinds of breakfast.

    The results show that if a person eats a right breakfast, he or she will work better than if he or she has no breakfast. If a student has fruit, eggs, bread and milk before going to school, he or she will learn more quickly and listen more carefully in class. The result is opposite to what some people think. Having no breakfast will not help you lose weight (减轻体重). This is because people become so hungry at noon that they eat too much for lunch. They will gain weight (增加体重) instead of losing it. You will lose more weight if you reduce your other meals.

    While the start of a new school year is always exciting, this year was even more so for some elementary school students in Auckland, New Zealand. They became the world's first kids to be "taught" by a digital teacher, Will. Before you start imagining a human-like robot walking around the classroom, Will is just an avatar(化身) that turns up on the students' desktop, tablet, or smartphone screen when called.

    Thanks to a digital camera and microphone, the avatar not only responds to questions the kids may have, but also picks up non-verbal signals. For example, if a student smiles at Will, he responds by smiling back. This two-way communication not only helps draw the students' attention, but also allows the program's developers to monitor their involvement(参与) and make changes if needed.

    Vector's Chief Digital Officer, Nikhil Ravishankar, believes that Will-like avatars could be a novel way to attract the attention of the next generation. He says, "Using a digital human is a very popular method to deliver new information to people, and I have a lot of hope in this technology as a means to deliver rich and educational experience in the future." Greg Cross, the Chief Business Officer for Soul Machines, states that kids who have grown up in this digital time adapt(适应) to new technology quickly, and he hopes to develop the idea of digital humans in the area of educate further.

    The program, in place since August 2018, has been a great success so far. However, no mater how popular it becomes, Will is unlikely to replace human educators any time soon. For one, the avatar's knowledge base is severely limited. But more importantly, even the smartest digital avatars could never predict and react to all the unexpected situations that educators have to deal with on a daily basis. However, it could come in handy as a "personal teacher", providing kids with one-on-one help on the subjects or even topics.

    Plants are living things. So can they feel pain? Plants don't feel pain the same way animals and people do, says Anke Steppuhn. She is a scientist at the Free University of Berlin in Germany. "What we define as pain usually has to do with a nervous system," Steppuhn explains. When you put your hand too close to a hot stove, nerve cells send a signal to your brain. Your brain decodes (解码) that signal as pain. This causes you to pull your hand away before any serious damage is done.

    Plants don't have nerves or brains, so they can't feel pain like we do. "But plants do recognize when something is hurting them," Steppuhn says. Because they are rooted to the ground, they can't escape a dangerous situation. So they need other ways of fighting back.

    The biggest threat to a plant's life is getting eaten. Some plants grow sharp little hairs. Other plants produce bad-tasting or even harmful chemicals. These force an attacker to abandon its meal. A plant called bittersweet nightshade does something even smarter, Steppuhn found. When a slug (蛞蝓) chews holes in a nightshade' s leaf, liquid begins dripping (滴) around the wound. It is almost as if the plant were bleeding. The liquid is sugary nectar (花蜜), and it happens to be a favorite food of ants. In their effort to collect the nectar, the ants swarm (蜂拥而至) all over the injured plant. They will attack anything that stands in their way. That includes the slug that damaged the plant in the first place. It's a very clever trick. Whenever a slug attacks a plant, the plant calls an army of ants to kill the slug.

    Nectar isn't the only way plants attract bodyguards. They also release certain chemicals into the air when they are being eaten. People usually can't detect these smells. But wasps (黄蜂) can. When a wasp detects this cry for help, it races to the scene of the crime. If it finds the right kind of insect chewing down on the plant, the wasp will interrupt the attacker's meal. It will do this by laying eggs inside the insect's body!

    who doesn't love sitting beside a cosy（舒适的）fire on a cold winter's night ? Who doesn't love to watch flames (火苗) curling up a chimney ? Fire is one of man's greatest friends, but also one of his greatest enemies. Many big fires are caused by carelessness. A lighted cigarette thrown out of a car or train window or a broken bottle lying on dry grass can start a fire. Sometimes, though, a fire can start on its own. Wet hay (草) can begin burning by itself. This is how it happens: the hay starts to rot (腐烂) and begins to give off heat which is trapped inside it. Finally, it bursts into flames. That's why farmers cut and store (贮存) their hay when it's dry .

    Fires have destroyed whole cities. In the 17th century, a small fire which began in a baker's shop burnt down nearly every building in London. Moscow was set on fire during the war against Napoleon. This fire continued burning for seven days . And, of course, in 64 A. D. a fire burnt Rome. Even today, in spite of modern fire - fighting methods, fire causes millions of pounds' worthy of damage each year both in our cities and in the countryside. It has been wisely said that fire is a good servant but a bad master.
