Ever order a drink, and feel cheated on the pour? Before you trouble the waiter, take a closer look at the size of your glass. “People will generally think there being less in larger containers, than in smaller ones.” Says Theresa Marteau, a behavioral scientist at the University of Cambridge, in England.

    She and her workmates had analyzed（分析）how larger amounts—and larger plates—trick us into eating more food. And they wondered: could the same be true for alcohol?

    So the researchers convinced the employees at a local bar to run an experiment: every two weeks, for four months, they'd change the bars wine glasses from the standard 300 milliliter size, to either slightly larger—370 milliliters, or slightly smaller—250 milliliters. They saw how the size of the glass affected customers' drinking habits, even though the pour, the amount of alcoholic drinks, was unchanged.

    It turned out that serving wine in smaller glasses had no measurable effect. But the large glasses increased wine sales 10 percent-even after controlling for day of the week, temperature, holidays and so on. The reason? “When the wine, the same amount, is being served in a larger glass, people are probably thinking they've got less in there.” Which, she says, means they might drink more, believing they haven't hit their nightly limit. Or, they might just feel less satisfied with the pour, and buy another round. The study appears in the journal BMC Public Health.

    Marteau says that, if later studies confirm this effect, public health officials might consider directing a certain average glass size. “Stating clearly the largest size in which wine can be sold could be a measure to reduce the overconsumption（过度消耗）of alcohol that seems to be shown by the glass size.” Until that happens, the bar in the study now always serves its wine in the larger glasses.

    In 1943, when I was 4, my parents moved from Coeur d'Alene, Idaho, to Fairbanks, Alaska, where adventure was never very far away.

    We arrived in the summer, just in time to enjoy the midnight sun. All that sunlight was fantastic for Mom's vegetable garden. Working in the garden at midnight tended to throw her timing off, so she didn't care much about my bedtime.

    Dad was a Railway Express agent and Mom was his clerk. That left me in a mess. I usually managed to find some trouble to get into. Once I had a little fire going in the dirt basement of a hotel. I had tried to light a barrel(桶) of paint but couldn't really get a good fire going. The smoke got pretty bad, though, and when 1 made my exit, a crowd and the police were there to greet me. The policemen took my matches and drove me home.

    Mom and Dad were occupied in the garden and Dad told the police to keep me, and they did! I had a tour of the prison before Mom rescued me. I hadn't turned 5 yet.

    As I entered kindergarten, the serious cold began to set in. Would it surprise you to know that I soon left part of my tongue on a metal handrail at school?

    As for Leonhard Seppala, famous as a dog sledder, I think I knew him well because I was taken for a ride with his white dog team one Sunday. At the time I didn't realize what a superstar he was, but I do remember the ride well. I was wrapped (包裹) heavily and well sheltered from the freezing and blowing weather.

    In 1950, we moved back to Coeur d'Alene, but we got one more Alaskan adventure when Leonhard invited us eight years later by paying a visit to Idaho to attend a gathering of former neighbors of Alaska.

    Literature is an important part of a total language arts program at all grade levels because of the many benefits it offers.

    Literature provides pleasure to listeners and readers. It is a relaxing escape from daily problems, and it fills leisure moments. Making time for recreational reading and using high-quality literature help to develop enthusiastic readers and improve achievement. Developing a love of literature as a recreational activity is possibly the most important outcome of a literature program.

    Literature builds experience. Through reading, children expand their horizons through vicarious(引起共鸣的)experiences. They visit new places, gain new experiences, and meet new people. They learn about the past as well as the present and learn about a variety of cultures, including their own. They discover the common goals and similar emotions found in people of all times and places. Nory Ryan's Song by Patricia Reilly, Giff, a hard survival story, is set in Ireland during the potato hunger of I845,and Patricia Polacco's The Butterfly, deals with Nazis, resistance, and Jewish persecution(迫害)during World War II.

    Literature provides a language model for those who hear and read it. Good literature exposes children to correct sentence patterns, standard story structures, and varied word usage. Children for whom English is a second language can improve their English with the interesting context, and all children benefit from new vocabulary that is woven into the stories.

    Literature develops thinking skills. Discussions of literature bring out reasoning related to sequence; cause and effect; character motivation; predictions; visualization of actions, characters, and settings; critical analysis of the story; and creative responses.

    Literature helps children deal with their problems. By finding out about the problems of others through books, children receive insights into dealing with their own problems, a process called bibliotherapy. Children might identify with Gilly, living angrily in a foster home in Katherine Paterson's The Great Gilly Hopkins, or with Mary Alice, a city girl forced to live with her grandma in a "hick town" in Richard Peck's A Year Down Yonder.

    People have different ways of dealing with a common cold. Some take over-the- counter(非处方的) medicines such as aspirin while others try popular home remedies(治疗)like herbal tea or chicken soup. Yet here is the tough truth about the common cold: nothing really cures it.

    So why do people sometimes believe that their remedies work? According to James Taylor, professor at the University of Washington, colds usually go away on their own in about a week, improving a little each day after symptoms peak, so it's easy to believe it's medicine rather than time that deserves the credit, USA Today reported.

    It still seems hard to believe that we can deal with more serious diseases yet are powerless against something so common as a cold. Recently, scientists came closer to figuring out why. To understand it, you first need to know how antiviral(抗病毒的) drugs work. They attack the virus by attaching to and changing the surface structures of the virus. To do that, the drug must fit and lock into the virus like the right piece of a jigsaw(拼图), which means scientists have to identify the virus and build a 3-D model to study its surface before they can design an antiviral drug that is effective enough.

    The two cold viruses that scientists had long known about were rhinovirus(鼻病毒) A and B. But they didn't find out about the existence of a third virus, rhinovirus C, until 2006. All three of them contribute to the common cold, but drugs that work well against rhinovirus A and B have little effect when used against C.

    "This explains most of the previous failures of drug trials against rhinovirus," study leader Professor Ann Palmenberg at University of Wisconsin-Madison, US, told Science Daily.

    Now, more than 10 years after the discovery of rhinovirus C, scientists have finally built a highly-detailed 3-D model of the virus, showing that the surface of the virus is, as expected, different from that of other cold viruses.

    With the model in hand, hopefully a real cure for a common cold is on its way. Soon, we may no longer have to waste our money on medicines that don't really work.

    We've heard of robots and AI (Artificial Intelligence) taking human jobs, but I bet mayors（市长）don't really think their jobs can be threatened any time soon. They were wrong, and the AI running for the mayor of a Tokyo district was clear proof of that.

    AI can't legally run for high-ranking public management positions yet, but one mayoral candidate from Tama City, Tokyo, intended to maximize the use of artificial intelligence in running city affairs. He was running his campaign (竞选运动) as "AI Mayor". Basically, he was suggesting replacing human public officials with AI and having them collect city data and create fair and balanced policies that will benefit everyone.

    "For the first time in the world, AI will run in an election," human candidate Michihito Matsuda announced on Twitter. "Artificial Intelligence will change Toma City. With the birth of an AI Mayor, we will conduct balanced politics."

    The AI Mayor was campaigning very much like its human competitors. Posters were shown all over Tama City and campaign trucks were blaring out(大声鸣响)promises of an AI utopia (乌托邦)and asking for support.

    Some people called Michihito Matsuda's campaign a stunt (噱头), as a human would still be the one legally in charge. However, others said that they were excited about the future of AI running things in the background, adding that it had to be a better choice.

I was standing in the checkout line behind a woman who looked to be in her 60s. When it was her turn to pay, the cashier greeted her by name and asked her how she was doing.

The woman looked down, shook her head and said: "Not so good. My husband just lost his job. The truth is, I don't know how I'm going to get through these days." Then she gave the cashier food stamps (食品券).

My heart ached. I wanted to help but didn't know how. Should I offer to pay for her groceries, or ask for her husband's resume (简历)?

Walking into the parking lot, I spotted the woman returning her shopping cart. I remembered something in my purse that I thought could help her. It wasn't a handful of cash or an offer of a job for her husband, but maybe it would make her life better.

"Excuse me," I said, my voice trembling a bit. "I couldn't help overhearing what you said to the cashier. It sounds like you're going through a really hard time right now. I'm so sorry. I'd like to give you something."

I handed her the small card from my purse. When the woman read the two words "You Matter" on the card, she began to cry. And through her tears, she said: "You have no idea how much this means to me."

I was a little startled by her reply. Having never done anything like this before, I didn't know what kind of reaction I might receive. All I could think to say was: "Would it be OK to give you a hug?"

A few days earlier, one of my workmates gave a similar card to me as encouragement for a project I was working on. When I read the card, I felt a warm glow spread inside of me. Deeply touched, I ordered my own box of "You Matter" cards and started sharing them.
