One of the most successful singers of the twentieth century, Ella Fitzgerald has made several different styles of her own. She was born in Virginia but was brought up in an orphanage in Yonkers, New York. Chick Webb spotted her in an amateur competition when she was sixteen. He engaged her to sing with his band and when he died in 1939, she took over.

    Unlike Bessie Smith, Ella Fitzgerald taught herself the sentimental music so popular in the 1930's — songs like “My Heart Belongs to Daddy”— and her recordings became best-sellers. During the 1940's she developed her own “scat singing” — a breathless, nonsense—syllable style—for songs like “Flying Home” and “Lady Be Good.”

    Ella Fitzgerald was the perfect musical partner for her friend, the trumpeter Louis Armstrong, matching him in warmth and artistry. “I just like music, period,” she said. “To me, it's a story. There's only one thing better than singing…. It's more singing.”

    Mail lay scattered across the kitchen table. I couldn't put off sorting through it any longer. I checked the envelopes, putting aside the ones addressed to my husband.

    It had been over three years since Bob had died. To friends and family it looked like I had moved past the worst of my sorrow. I took care of my house, socialized and kept up with community. On the outside everything appeared to be normal. But inside I was anything but I worried I would never get better, never be myself again. They say sorrow has no set time limit, but I was so tired of feeling empty and hopeless. My sorrow was sharp and fresh as ever. It was like a wall of pressure in my chest, pressing my heart.

    I picked up a piece of Bob's mail and held it out to tear in half, but stopped myself from cutting up the envelope. The letter was from an organization that funded a Haitian orphanage called My Father's House. Its founder, Carol Hawthorne, had given a presentation at our church. Bob and I had donated, and Bob ended up on the mailing list to receive the newsletter (通讯) with updates on the children.

    I hadn't read one since Bob died. But just three months before, in January 2012, the country had been hit by a terrible earthquake. In my depressed state, it hadn't even occurred to me to wonder whether the orphanage had survived. I opened the newsletter and was surprised to find out that My Father's House was still standing. Of course now it was more crowded than ever. At the bottom of the page was an announcement about an upcoming trip to visit the orphanage in person. “I should go.” The thought wouldn't leave me. I contacted Carol Hawthorne.“What would I do if I go?” I asked.“Build houses?”

    “The Haitian people there are eager to work and they know what they're doing,” said Carol. “What they need are raw materials, and we provide them. We also visit with the children. We go to clinics and schools, pass out supplies. You'll be very busy, I promise!” I reserved a seat but didn't mention it to any of my friends. Just a few weeks later, I was at the airport with seven strangers, waiting to board a plane to Haiti. Even after takeoff I wasn't really sure of what I was doing.

    In Haiti we were met by Pastor Ronald Lefranc, the director of My Father's House. We piled into an old school bus and drove over uneven roads full of stones and mud. We passed women shaking under the weight of huge water buckets balanced on their heads. Piles of rubbish scattered across the landscape, and the land was covered with broken tents. Finally we pulled up to the orphanage. A crowd of children—52 in all—rushed up to greet us. I couldn't understand the words of the song they sang in Creole, but with the smiles on their faces I didn't need to. Each child planted a big kiss on my cheek.

    Carol and Pastor Ronald led us into the main building. “What are those over there?” I asked, pointing to a collection of thin tents. “Is there not enough room in the building for all the children?”

    “We have the room,” said Pastor Ronald. “But many of these children came here after the earthquake. They still don't feel safe sleeping under a roof.”

    There was no sign of fear in the playroom inside. I played dolls and other games. Children I'd just met presented me with pictures they'd drawn and letters written in Creole. In the evening the children gathered in the dining room. They took turns reading aloud and then they all joined in song. The words were strange, but the tune sounded familiar.

    They'd lost so much, yet were so joyful. In the evening the children gathered in the dining room. One of the older children stood up to speak and then they all joined in song. The words were strange, but the tune sounded familiar. The children settled down. In the silence, a quiet noise began.

    ARNOLD Schwarzenegger is back, once again taking on his iconic killer robot role, the T-800, in August's new movie Terminator Genisys. While the T-800 model—even if it can be evil—has a fond place in moviegoers' hearts, the reality of autonomous machines is no joke, according to scientists.

    Autonomous weapons use artificial intelligence (AI) to choose targets without human help. They were described as “the third revolution in warfare, after gunpowder and nuclear arms” in an open letter signed by over 1,000 important technology figures in July. The list included British scientist Stephen Hawking and Apple co-founder Steve Wozniak. They asked governments around the world to ban autonomous weapons, warning that killer robots could start ethnic cleansings and an arms race.

     “They will look like tanks. They will look like battleships. They will look like jet fighters,” UK robotics professor Noel Sharkey told CNET, a leading technology website.

    But unlike these machines, which require a human hand in their action, so-called “killer robots” would have some decision-making abilities and the ability to act on their own.

     “If any major military power pushes ahead with AI weapon development, a global arms race is almost inevitable,” said the letter released at the 2015 International Joint Conference on Artificial Intelligence in Buenos Aires, Argentina.

    The idea of an automated killing machine was made famous by Schwarzenegger's first Terminator movie in 1984. While no red-eyed robots have been sent after human beings, the idea of AI being used as a weapon has gotten much more likely in the years ever since. The US military is already developing autonomous flying vehicles that can carry out all the steps of a strike mission without a human controlling them, according to a May report in Nature magazine.

    Scientists have even painted a destructive picture of autonomous weapons falling into the hands of terrorists or warlords hoping to carry out ethnic cleansings.

     “The development of full artificial intelligence could lead to the end of the human race,” Hawking said to the BBC in 2016.

Authorities are gradually waking up to the risk of robot wars. Last May, for the first time, the United Nations brought governments together to begin talks on autonomous weapons systems.

    Still, a ban on autonomous weapons is “easier said than done”, commented The Guardian. The dual (双重的) uses of the AI technology—for harm and for good—is difficult to manage. This is because the exact same technology can be used in a wide range of ways, the paper said.

    I was ever bullied badly when I was in high school. One kid in particular would try to make me feel worse in every way he knew. For example, he would throw stuff at me constantly, hit me on the head, punch(殴打)me, call me ugly and stupid, make fun of me and, of course tell me he would beat me up if I ever fought back. It was like his daily mission.

    And it was my daily mission to just get through the day. What could I say? It made my world very small because that was my main focus- just surviving. Everything else fell by the wayside. Unfortunately, that included any form of social life. So not only was my world tiny, but it was very lonely

    Looking back to that time, which was about 11years ago, my biggest mistake was not bringing anyone into that world of mine. I was too proud (and embarrassed) to get help. I would rather not face the fact that I needed help because in my mind, that would mean that the bully won. It would also mean that I was weak.

    Let me just say this: bullying someone is a weak choice. The only reason why they come after you is that they think you won't do anything about it. Does that make anyone strong? Absolutely not. Be stronger-ask a parent, a teacher or a friend for help. Simply admit that you are struggling and need help.

    You can put it like this, "Somebody who is weak and trying to build himself or herself up has chosen to do that by putting me down. The only reason why they are doing that is that I am nice and I haven't done anything about it yet. Well I am through putting up with this. I have basic human rights that they are trying to take away to feel better and that is just not OK. How do I handle this? I don't want the pain cycle to continue and I don't want to become someone I don't want to be.

    I live a different life in every season. Life in the summertime is often full of pests. Like most Long Island homeowners, I want to ensure my suburban life with pest-free living. So it was with wide-eyed surprise that I greeted the smiling exterminator (灭虫者) who rang my bell.

    “We'll be serving your neighbors, Mike and Sarah (I'm not familiar with either one by name),” he waved in the other direction. “Since we'll have a team here tomorrow, we're offering a discount. ” He came out with numbers beginning from $299 then in seconds to $89.

    “You've probably been seeing the ant hills around.” he moved toward my front walkway and lawn. “And have you seen the bees that dig nests in the ground?” he continued with his head shaking up and down pushing me to do the same.

    “What we do is spray three feet out from your foundation and three feet up.” As he was talking, and without breaking eye contact, he opened his iPad cover and began operating at the screen to show me frightening images. “It also kills other pests, like spiders. It is the best pesticide (杀虫剂),” he said, pausing for effect.

    He then went into soft talk to close the deal, correctly foreseeing that I would be concerned about safety and the environmental impact on my vegetable garden, plants and our little patch of planet here on Long Island. “The products are environmentally responsible, safe with children and pets,” he said.

    I'm unkind when it comes to unwanted visitors entering on my out-of-doors moments. Any insect found in my house or on my deck is bound to be poisoned or pancaked.

    Unfortunately for the exterminator, just as I was considering buying the pesticide, Billy, my fearless husband, pulled into our driveway, which made me ask for a business card out of politeness instead.

We all know how it feels to get lost in a great book. But what's happening in our brains as we dive into it? How is it different from what happens as we experience real life? Now, a new study led by Dr Leila Wehbe and Dr Tom Mitehell of Carnegie Mellon University have provided partial answers to these questions. 

Since reading comprehension is a highly complex process, earlier studies tried to break that process down and focus on just one aspect at a time: mapping fMRI signatures（特征）associated with processing a single word or sentence, for example. "It's usually not like reading a book, and usually the stimulus（刺激物）consists of out-of-context sentences designed specifically for the experiment"

To address these issues, the researchers developed a computer program to look for patterns of brain activity that appeared when people read certain words, specific grammatical structures, particular characters" names and other aspects of the story—a total of 195 different "story features". In the study, they first asked eight volunteers to read Chapter 9 of Harry Potter and the Sorcerer's Stone and recorded their brain activity using an fMRI scanner（扫描仪）. Then the researchers fed the volunteers' fMRI data into their computer program and had the program identify the responses of different brain regions to the 195 features mentioned above. 

The result showed that when the volunteers read descriptions of physical movement in the story, there was significantly increased activity in the posterior temporal cortex, the region involved in perceiving real-world movement. Besides dialogue was specifically related with the right temporoparietal junction, a key area involved in imagining others thoughts and goals. "This is truly shocking for us as these regions aren't even considered to be part of the brain's language system," Wehbe says. 

Next, Wehbe and Mitchell hope to study how and why language processing can go wrong. "If we have a large enough amount of data", Wehbe says, "we could find the specific ways in which one brain—for example, the brain of a dyslexic（诵读困难的）person—is performing differently from other brains." And this, the researchers think, may someday help us design individually tailored（特制的）treatments for dyslexia and other reading disorders.
