    My parents were in a huge argument, and I was really upset about it. I didn't know who I should talk with about how I was feeling. So I asked Mom to allow me to stay the night at my best friend's house. Though I knew I wouldn't tell her about my parents' situation, I was looking forward to getting out of the house. I was in the middle of packing up my things when suddenly the power went out in the neighborhood. Mom came to tell me that I should stay with my grandpa until the power came back on.

    I was really disappointed because I felt that we did not have much to talk about. But I knew he would be frightened alone in the dark. I went to his room and told him that I'd stay with him until the power was restored. He was quite happy and said, “Great opportunity.”

    “What is it?” I asked.

    “To talk, you and I” he said. “To hold a private little meeting about what we're going to do with your mom and dad, and what we're going to do with ourselves now that we're in the situation we are in.”

    “But we can't do anything about it. Grandpa,” I said, surprised that here was someone with whom I could share my feelings and someone who was in the same “boat” as I was.

    And that's how the most unbelievable friendship between my grandfather and me started. Sitting in the dark, we talked about our feelings and fears of life — from how fast things change to how they sometimes don't change fast enough. That night, because the power went out, I found a new friend, with whom I could safely talk about all my fears and pains, whatever they may be. Suddenly, the lights all came back on. “Well,” he said, “I guess that means you'll want to go now. I really like our talk. I hope the power will go out every few nights!”

    Do you know how it is when you see someone yawn and you start yawning too? Or how hard it is to be among people laughing and not laugh yourself? Well, apparently it's because we have mirror neurons (神经元) in our brains.

    Put simply, the existence of mirror neurons suggests that every time we see someone else do something, our brains imitate it, whether or not we actually perform the same action. This explains a great deal about how we learn to smile, talk, walk, dance or play sports. But the idea goes further: mirror neurons not only appear to explain physical actions, they also tell us that there is a biological basis for the way we understand other people.

    Mirror neurons can undoubtedly be found all over our brains, but especially in the area which relate to our ability to use languages, and to understand how other people feel. Researchers have found that mirror neurons relate strongly to language. A group of researchers discovered that if they gave people sentences to listen to (for example: “The hand took hold of the ball”), the same mirror neurons were triggered as when the action was actually performed (in this example, actually taking hold of a ball).

    Any problems with mirror neurons may well result in problems with behavior. Much research suggests that people with social and behavioral problems have mirror neurons which are not fully functioning. However, it is not yet known exactly how these discoveries might help find treatments for social disorders.

    Research into mirror neurons seems to provide us with ever more information concerning how humans behave and interact. Indeed, it may turn out to be the equivalent for neuroscience of what Einstein's theory of relativity was for physics. And the next time you feel the urge to cough in the cinema when someone else does-well, perhaps you'll understand why.

    Getting stuck in a traffic jam is one of the most boring problems for people living in big cities. The fact that you're moving so slowly leads too stress, anger and the wish that your car could just fly over the traffic like an airplane.

    Soon, however, that wish could come true .On May 8, US car-renting company Uber showed off what it described as "the transportation mode of the future: on-demand air transport," reported ABC News.

    According to Nikhill Goel, head of products for Uber Air, the company's air taxi service may launch test flights in the US cities of Dallas and Los Angeles, as well as Dubai in the United Arab Emirates, as early as 2020. If everything goes according to plan, passengers will be able to fly to work by 2023.

    When the Olympics comes to Los Angeles in 2028. Uber "expects to have hundreds, if not thousands, of its aircraft in the skies." Goel told Newsweek.

    So what would Uber's flying vehicles be like?

    They are small, electric aircraft that take off and land vertically (垂直地) , and they give off zero emissions (排放) and are quiet enough to operate in cities .

    Just like an airplane, the vehicles will have fixed wings to help them glide. But while a helicopter has just one big fixed rotor (定量). Uber's vehicles will have multiple rotors , which will help increase fuel efficiency (效率) while reducing emissions and noise.

    Because of these fixed wines and multiple rotors. Uber's flying taxis "should be quieter and safer than a helicopter." reported ABC News.

    However, the service still has a long way to go before it's ready to accept passengers. For example, to avoid any potential accidents. Uber is working with NASA to study air traffic control problems associated with low-flying aircraft. But just as Dubai's Mayor Betty Price said in a news release. "This program is revolutionary and future -oriented (面向未来的)."

    Closeness and independence are both important in our life. Though all humans need both of them, women tend to focus on the first and men on the second. It is as if their lifeblood ran in different directions.

    These differences can give women and men differing views of the same situation, as they did in the case of couple I will call Tracy and Brian. When Brian's old high school friend called him at work and announced he'd be in town on business the following month, Brian invited him to stay for the weekend. That evening he informed Tracy that they were going to have a houseguest, and that he and his friend would go out together the first night to chat like old times. Tracy was upset. She was going to be away on business the week before, and the Friday night when Brian would be out with his friend would be her first night home. But what upset her the most was that Brian had made these plans on his own and informed her of them, rather then discussing them with her before extending the invitation.

    Tracy would never make plans, for a weekend or an evening, without first checking with Brian. She can't understand why he doesn't show her the same courtesy and consideration that she shows him. But when she protests, Brian says, "I can't say to my friend, 'I have to ask my wife for permission'!"

    To Brian, checking with his wife means seeking permission, which implies that he is not independent, not free to act on his own. To Tracy, checking with her husband makes her feel good to know and show that she is involved with someone, that her life is bound up with someone else's.

    Tracy and Brian both felt upset by this incident because it cut to the core of their primary concerns. Tracy was hurt because she sensed a failure of closeness in their relationship: He didn't care about her as much as she cared about him. And he was hurt because he felt she was trying to control him and limit his freedom.

    I particularly enjoy the works of Greenwich Village poet Edward Field, whose interest in cinema led to a number of poems based on old monster movies (including many about Frankenstein and my favorite, Curse of the Cat Woman).

    There are so many to choose from! I love Robert Frost, especially "Mending Wall", mostly because he is my dad's favorite poet. However, personally I love Lnagston Hughes's poem "Dreams" because it always brings happiness to me. I am also a big fan of the older poems, such as Spenser's "One Day I Wrote Her Name Upon the Strand" because it is so simple, and "The Tyger" and "The Lamb" by William Blake because I love the language.

    My favorite poet is Suji Kwock Kim. Ever since I read her book of poetry "Notes from the Divided Country", I have been a big fan of her clear and thoughtful writing. My favorite poem of hers is "Borderlands", which she wrote in memory of her grandmother. It is a poem about her grandmother's experiences during the war.

    Hard to decide! But if I have to, I'd say Emily Dickinson. Her life was so wonderful and her opinions about life are also interesting. Her understanding of nature speaks to the heart of anyone who loves the outdoors! Dickinson also understood human nature very well. Her poems speak of love, loneliness, ect. Finally, my favorite poem by her is "I Never Saw a Moor". I love her thoughts!

    I didn't know how to say no, and was afraid to tell people what I wanted. Instead, I got myself tangled (纠结的) in a web of obligations, anxiety, and white lies.

    The worst thing was that I didn't even realize what I was doing. I thought I knew how to say "no"—but couldn't remember the last time I had. Like a lot of people, I just wanted to be accepted, appreciated, loved—and that the only way to get those things was to put everyone else's needs before my own.

    I never seemed to have time for things I really wanted to do. I'd like to learn Spanish, write more fiction, and travel. These aren't huge, unrealistic goals. And yet, my people-pleasing ways dramatically cut into my free time to pursue these desires.

    But recently, I decided I'd had enough. As an experiment, I began standing up for myself, even at the risk of alienating (使疏远) myself from everyone and having my entire life come crashing down around me. Several days ago, a good friend asked me to go for coffee at 5 p.m. I was planning to hit the gym and then binge—watch Mad Men for the millionth time. I said, "Sorry, I've got things I want to do tonight." She said, "That's fine. Maybe another time." It was all so painfully simple that I wanted to cry.

    Saying "no" is so much easier. If someone asks me to do something I have zero interest in, I'm polite but honest. "I'm sorry, I don't think that's really for me." The words slip out my mouth faster than some other lame excuses.

    Learning how to say "no" has added several extra hours to my days, days to my weeks, and what feels like months to my years. I no longer have to back-burner my plans to help friends with their job search, or set aside a weekend to read a book draft by someone I barely know. Saying "no" has set me free.
