It's generally believed that people act the way they do because of their personalities and attitudes. They recycle their garbage because they care about the environment. They pay $5 for a caramel brulee latte because they like expensive coffee drinks.

    It's undeniable that behavior comes from our inner dispositions(性情), but in many instances we also draw inferences about who we are, as suggested by the social psychologist Daryl Bern, by observing our own behavior. We can be strangers to ourselves. If we knew our own minds, why should we need to guess what our preferences are from our behavior? If our minds were an open book, we would know exactly how much we care about the environment or like lattes. Actually, we often need to look to our behavior to figure out who we are.

    Moreover, we don't just use our behavior to learn about our particular types of character — we infer characters that weren't there before. Our behavior is often shaped by little pressures around us, which we fail to recognize. Maybe we recycle because our wives and neighbors would disapprove if we didn't. Maybe we buy lattes in order to impress the people around us. We should not mistakenly believe that we always behave as a result of some inner disposition.

    Whatever pressures there can be or inferences one can make, people become what they do, though it may not be in compliance(符合) with their true desires. Therefore, we should all bear in mind Kurt Vonnegut's advice: “We are what we pretend to be, so we must be careful about what we pretend to be.”

    A 60-year-old homeless woman named Smokie has been sleeping outside in the dirt a few doors down from a man named Elvis Summers.

    Most mornings, she stops by Elvis's Los Angeles apartment and asks if he has any recyclable materials for her. Through these conversations, they struck up a friendship.

    One morning, Elvis saw a news article about man in Oakland who has been making tiny houses out of deserted materials. He was inspired to put off paying a few bills so he could buy the wood and hardware to make Smokie a brand new shelter. It took him five days to build it, and now, for the first time in ten years, Smokie has a place to hang the sign “Home Sweet Home”.

    “I had nowhere to really build it, so I just built it in the street outside of my apartment,” Elvis told Good News Network. “The local LAPD police have been super cool, and have told me they support it—as long as we move it to a different spot every 72 hours.”

    He made this pretty time-lapse(延时的) video showing how he did it. The materials, including two locks on the front door and strong wheels for moving it around, cost him about $500.

    “I've met so many homeless people, good people,” Elvis said in an email, “Since I built Smokie's , I've had several people asking me to make them a tiny home and it's turned into much more than just the one house I wanted to build.”

Although he runs an online retail store that sells EDM clothes, he has decided to launch an ambitious project to fund more shelters. He plants to get lighter and cheaper materials—without sacrificing the strength of the house—for the next round. Rick Sassen, a branch manager, kindly donated the roof shingles and cedar supporting Smokie's house, final items Elvis couldn't afford on his own. Sassen has promised to work out a deal on future building materials for the same cause.

    Tyler Skiuzacek's father，Patrick，could not sleep through the night．It was 2007，and Patrick had just returned from a year in Iraq，where he served in the U．S．Army．Patrick Skluzacek was energetic and happy when he left for Iraq，Tyler says．But when he returned，he was unhappy and drinking alcohol too much．It turned out Patrick was suffering from sleep panic attacks．Patrick would wake up every night．His heart would beat too fast．He would sweat．The nighttime panic attacks prevented Patrick from feeling good the next day，because he was so tired．

    Almost 10 years later，Tyler was in a position to help his father．He thought he could make a computer program that might help his father．So he entered a competition in Washington，D．C，trying to solve the problem Tyler's father and other U．S．war veterans(老兵)，were having．People called them “night terrors.”The students had 36 hours to come up with a program．They called it myBivy．That name comes from bivouac，a military term for a safe place to sleep．

    The application uses a smart watch and a smart phone together．The watch tracks the wearer's heartbeat．It sends the data to the program on the smart phone．Research shows that a person's heart rate will increase right before a night terror．So if the wearer's heartbeat started to rise，my B ivy would respond．The smart watch would vibrate(振动)and gently wake up the sleeping person．That was enough to prevent a night terror from happening．

    Patrick wore the watch for two weeks to get used to it．Then，Tyler turned on the application．On the first night，the vibrations from the watch prevented 10 nightmares．Patrick said he had not slept that well in many years．Tyler and his team won the contest in Washington，D．C．The prize was $1，500．Then the group tried to raise more money from investors，and they were surprised when they took in over$25，000．By the spring of 2016，Tyler and his team were testing the app with volunteers，and hoped to make it availab1e to the public soon．

    Students in many countries are learning English. Some of these students are little children. Others are teenagers. Many are adults. Some learn at school, others learn by themselves. A few learn English over the radio, on TV, or in films. One must work hard to learn another language.

    Why do all these people want to learn English? It's difficult to answer this question. Many boys and girls learn English at school because it is one of their subjects for study. They study their own language, math, English, and so on. Some people learn it because it is useful for their work. Many people learn English for their work and higher studies, because at colleges or universities some of their books are in English. Other people learn English because they want to read newspapers or magazines in English.

    It's 11 p.m., and I'm still sitting here writing this article for the school magazine! I've had two weeks to write it, and my teacher, Julia, wants it tomorrow. She's always complaining (抱怨) that I leave things till the last minute. Maybe she's right.

    A month ago I made a decision to be more efficient (有效率的) this year. Well, I've clearly failed. I've also been trying to get fitter for four weeks now. I've started going to the health club. I've even been going to bed earlier. But I'm not feeling any fitter, just a little unhappier. I miss my bad habits. Why is leading a better life so hard?

    I've just read an article on a website, and I've discovered that it isn't my fault (过错)! In fact, it isn't anyone's fault. It's our brain's. It's programmed to make it difficult to break bad habits. There's nothing we can do. Scientists have done experiments that show we use one part of our brain when we think about ourselves and another when we think about other people. However, when we think about ourselves in the future, we use the same part of the brain that we usually use to think about other people. In other words, the brain sees the “future you” as a different person than your “present you.” That's why we don't always find it easy to make good decisions for ourselves in the future.

    But that's not all. Scientists have also discovered that it takes around ten weeks to form a good habit. That's the amount (数量) of time the brain needs to accept new behavioral patterns (形式). The good news is that once you make it to ten weeks, everything becomes a lot easier. The bad news is that ten weeks is a really long time, so it's easy to give up what you want to do before then.

    So even when we want to change our ways and become better people, our brains won't let us. Or is this just an excuse? Look — I've finished my article on time! Anything is possible!
