A parent might place his daughter's drawing on the fridge out of a love for his child rather than for the wonderful image, but for many people, that children art is actually quite amazing. In fact, adult artists were often inspired by children's drawing. For the museum-goers out there who tend to point to a piece of modern art and say, “My kid could have made that !”It's worth remembering that often, that's actually just what the artist had in mind.

    For many kids, drawing is exciting not because of the final product it leads to, but because they can live completely in the world of their drawing for a few minutes. Even children are scribbling(涂鸦), they're representing through action, not through pictures. Liane Alves, a prekindergarten teacher, recalled a student who presented her with a drawing featuring a single straight line across the page. Alves assumed the child hadn't given too much thought to the drawing until he explained that the line was one of the stems (茎) from The Princess and the Pea, one of the fairy tales they read in class.

    Maureen Ingram, who's a preschool teacher at the same school,said her students often tell different stories about a given piece of art depending on the day, perhaps because they weren't sure what they intended to draw when they started the picture. “We as adults will often say, 'I'm going to draw a horse, 'and we set out. . . and get frustrated when we can't do it, ”Ingram said. “Children seem to take a different approach, where they just draw, and then they realize, 'it is a horse. '”

    And what about those odd or scary-looking drawings? Does that mean kids are telling themselves stories that are odd or scary? It's hard to say, but it's rarely a good idea to over-interpret it. Ellen Winner, a psychology professor, pointed to parents who worry when their kid draws a child bigger than the adults. What's most important to remember is that“children's art has its own logic,” Winner said. “Children are not being crazy. ”

    There's no doubt that water is vital to any life. About 60 percent of the average adult human body is made of water. This includes most of your brain, heart, lungs, muscles and skin, and even about 30 percent of your bones. Yet there's little scientific agreement about the exact amount of the stuff an individual should consume each day. So how much water do you actually need to drink to be healthy?

    You may have heard that you should drink eight 8-ounce glasses of water a day. Yet, the downside of this rule, researchers say, is that drinking water by the glass is not the only way that humans take in it. The “8 X 8” rule essentially overlooks two big sources of daily water consumption. One such source is food. Everything you eat contains some water. Watermelons, for example, are more than 90 percent water by weight. Different diets naturally contain different amounts of waters, and the counts. The other key water sources are other beverages. Non-alcoholic drinks such as coffee, and tea, contain mostly water and all contribute to your hydration（水量）.

    So, between all the food, water and other fluids you consume in a day, how much water should you aim to take in?

    The National Academics of Sciences suggests that woman consume a total of approximately 2.7 liters (91 ounces) of warm from all beverages and foods each day and men 3.7 liters (125 ounces). But these are just general guidelines.

    The truth is, there is no magic standard for hydration—everyone's need vary depending on their age, weight, level of physical activity, general health and even the climate they live in. The more water you lose, the more water you'll need to replace with food and drink. If you are looking for concrete advice, though, the best place to look is within. Drink up when you're thirsty.

    Eve was waiting in the corridor outside her class. She was feeling sick. She had two exams that day and physics was first. She really hated physics. It was her worst subject. Lisa looked back at her, and then looked away quickly. Eve thought she looked guilty. She didn't have a problem with physics. She didn't have a problem with anything... Miss Perfect!

    "Hi, Eve! So what's wrong with you and Lisa?" asked Tina, "I thought you were friends." "Yes, so did I," said Eve. "But she hasn't spoken to me for two weeks now. She promised to help me review for the physics exam too, but then she's ignored all my calls and texts."

    While in the exam, Eve found Lisa was holding her phone on her knee under the table and reading from it. Eve couldn't believe it! Is that how Lisa always got such good grades? She thought about telling the teacher, but she hesitated. The next exam was history. That was Eve's favorite subject but she couldn't concentrate. She didn't know what to do about Lisa. Just then, Mr. Reed, their teacher, walked past. "Mr. Reed…"

    Lisa was called to the teachers' office and there waited Mr. Reed…

    The history test was over. Eve was walking towards the school gate when she heard footsteps behind her. It was Lisa. Eve could see that she had been crying. "Listen," said Lisa. "I'm really sorry I haven't answered your calls, but my dad had a heart attack two weeks ago and he's in hospital. He had a big heart operation today and I was very worried about him. So I was reading texts from my mum, but Mr. Reed caught me. He thought I was cheating. He believes me now, but I have to take the exam again. I'm sorry I didn't tell you what was happening. Will you forgive me?"

    Have you ever run into a careless cell phone user on the street? Perhaps they were busy talking, texting or checking updates on WeChat without looking at what was going on around them. As the number of this new “species” of human has kept rising, they have been given a new name — phubbers（低头族）.

    Recently, a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities bury themselves in their phones. A doctor plays with his cell phone while letting his patient die, a pretty woman takes selfie（自拍照）in front of a car accident site, and a father loses his child without knowing about it while using his mobile phone. A chain of similar events eventually leads to the destruction of the world.

    Although the ending sounds overstated, the damage phubbing can bring is real. Your health is the first to bear the effect and result of it. “Constantly bending your head to check your cell phone could damage your neck,” Guangming Daily quoted doctors as saying. “the neck is like a rope that breaks after long-term stretching.” Also, staring at cell phones for long periods of time will damage your eyesight gradually, according to the report.

    But that's not all. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions with family or friends, many people tend to stick to their cell phones while others are chatting happily with each other and this creates a strange atmosphere, Qilu Evening News reported.

    It can also cost you your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their cell phones in broad daylight.

    Born in Detroit, Michigan, on January 10^th, 1928. Philip Levine was formally educated in the Detroit public school system. After graduation from university, Levine worked a number of industrial jobs, including the night work in factories, reading and writing poems in his off hours. In 1953, he studied at the University of Iowa. There, Levine met Robert Lowell and John Berryman, whom Levine called his “one great guide”.

    About writing poems, Levine wrote: “I believed even then that if I could change my experience into poems I would give it the value and honor that it did not begin to have on its own. I thought too that if I could write about it, I could come to understand it: I believed that if I could understand my life——or at least the part my work played in it——I could write it with some degree of joy, something obviously missing from my life.”

    Levine published (出版) his first collection of poems. On the Edge in 1961, followed by Not This Pig in 1968. Throughout his life Levine published many books of poems, winning many prizes. A review said: “Levine writes poems about the bravery of men, physical labor, simple pleasures and strong feelings, often set in working-class Detroit or in central California, where he worked or lived.”

    He taught for many years at California State University, Fresno and served as Distinguished Poet in Residence for the Creative Writing Program at New York University. After retiring from teaching, Levine divided his time between Brooklyn, New York, and Fresno, California, until his death on February 14^th, 2015. His final poem collection, The Last Shift, as well as a collection of essays (短文) and other writings, My Lost Poets: A Life in Poetry, were published in 2016.

    Have you ever pressed the pedestrian button at a crosswalk and wondered if it really worked? They're called “placebo(安慰剂）buttons” 一buttons that mechanically sound and can be pushed，but provide no functionality.

In New York City, only about 100 of the 1, 000 crosswalk buttons actually function. Crosswalk signals were generally installed before traffic jam had reached today's levels.

    But while their function was taken over by more advanced systems—such as automated lights or traffic sensors — the physical buttons were often kept, rather than being replaced at further expense. Other cities，such as Boston， Dallas and Seattle， have gone through a similar process, leaving them with their own placebo pedestrian buttons. In London, which has 6, 000 traffic signals， pressing the pedestrian button results in a reliable “Wait” light. But that doesn't necessarily mean that the “green man”— or “pedestrian stage” in traffic signal design profession — will appear any sooner.

    “We do have some crossings where the green light comes on automatically, but we still ask people to press the button because that enables accessible features,'' said Glynn Barton, director of network management at Transport for London.

    These features, such as blind tracks and hearable traffic signals, help people with visual disorder cross the road and only function when the button is pressed. As for the lights, a growing number of them are now combined and become a part of an electronic system that detects traffic and adjusts time frequency accordingly (giving priority to buses if they're running late, for example), which means that pressing the button has no effect.

    According to Langer, a Harvard psychologist, placebo buttons give us the illusion (错觉)of control — and something to do in situations where the alternative would be doing nothing. In the case of pedestrian crossings, they may even make us safer by forcing us to pay attention to our surroundings. “They serve a psychological purpose at the very least,” she added.
