    Most people have heard of Shakespeare and probably know something of the plays that he wrote. However，not everybody knows much about the life of this remarkable man，except perhaps that he was born in the market town of Stratford upon Avon and  that he married a woman called Anne Hathaway. We know nothing of his school life. We do not know，for example，how long it lasted，but we presume that he attended the local grammar school，where the principal subject taught was Latin.

    Nothing certain is known for what he did between the time he left school and his departure for London. According to a local legend，he was beaten and even put in prison for stealing rabbits and deer from the estate of a neighboring landowner，Sir Thomas Lucy. It is said that because of this he was forced to run away from his native place. A different legend says that he was apprenticed to a Stratford butcher，but did not like the life and for this reason decided to leave Stratford.

    Whatever caused him to leave the town of his birth，the world can be grateful that he did so. What is certain is that he set his foot on the road to fame when he arrived in London. It is said that at first he had no money or friends there，but that he earned a little by taking care of the horses of the gentlemen who attended the plays at the theatre. In_time ， as he became a familiar figure to the actors in the theatre，they stopped and spoke to him. They found his conversation so brilliant that finally he was invited to join their company.

    There's a trend that more city people decide that they want to grow crops and raise some live-stock (家禽). After all, there are few things more satisfying than biting into a bunch of tender, red carrots you grow yourself, or a fresh egg from the backyard.

    Most gardeners understand that the soil in big cities is often polluted with lead and know to get their soil tested. But most are pretty clueless about how to prevent other types of pollutants, like heavy metals and asbestos(石棉)from getting into their vegetables.

    Part of the problem is that “there might be pollutants that gardeners can't test for,” says Brent Kim, a program officer. Most soil tests look for lead, cadrniunt(镉)and arsenic(砷). But they don't test things like chemicals left behind by cars, which might have escaped into the soil.

    So if you're thinking of staring an urban garden, Kim says, once you've found a plot of land, you should learn what's now an empty plot or a backyard might once have been a parking lot, a gas station or a chemical ground. “Knowing its past will give you some idea about what might be in that soil,” he says.

    “People tend to think raised beds are going to solve their pollution problem,” Kim says. But polluted soil could easily kicked onto your plants, especially if the beds are low to the ground.

    “Another consideration is that you have to be careful about the materials that you're using to build a raised bed,” Kim says. Recycling wood from an old construction site might seem like a good, eco-friendly idea. But that wood could be treated with chemicals you don't want touching your fruits and veggies, Kim says. And it's always a good idea to use gloves while gardening, and wash all your produce thoroughly.

    “I see these urban growing spaces as these oases(绿洲)in the middle of these urban environments,” Kim says. “They bring communities together, and they help people save money on fresh produce. Urban growing spaces are amazing. Let's keep doing this, but let's do it safely.”

    Sandra Cisneros was born in Chicago in 1954 to a Mexican American family. As the only girl in a family of seven children, she often felt like she had “seven fathers,” because her six brothers, as well as her father, tried to control her. Feeling shy and unimportant, she retreated(躲避)into books. Despite her love of reading, she did not do well in elementary school because she was too shy to participate.

    In high school, with the encouragement of one particular teacher, Cisneros improved her grades and worked for the school literary magazine. Her father encouraged her to go to college because he thought it would be a good way for her to find a husband. Cisneros did attend college, but instead of searching for a husband, she found a teacher who helped her join the famous graduate writing program at the University of Iowa. At the university's Writers' Workshop, however, she felt lonely－a Mexican American from a poor neighborhood among students from wealthy families. The feeling of being so different helped Cisneros find her “creative voice”.

    “It was not until this moment when I considered myself truly different that my writing acquired a voice. I knew I was a Mexican woman, but I didn't think it had anything to do with why I felt so much imbalance in my life, but it had everything to do with it! That's when I decided I would write about something my classmates couldn't write about.”

    Cisneros published her first work, The House on Mango Street, when she was twenty-nine. The book talks about a young Mexican American girl growing up in a Spanish-speaking area in Chicago, much like the neighborhoods in which Cisneros lived as a child. The book won an award in 1985 and has been used in classes from high school to graduate school level. Since then, Cisneros has published several books of poetry, a children's book, and a short-story collection.

    Captain America and Blackpanther were about to defend Earth from the criminal Thanos when Kevin Foley first noticed something was wrong. Foley, a 46-year old information-technology worker from Kyle, Texas, was heading into the theater to see Avengers: Infinity War when he realized he was having trouble breathing normally. The same symptom struck again during another movie the following night, but more severe this time. Once the cast on the second film rolled, Foley took action: he looked at his wristwatch. It was a bigger step than you might imagine, because Foley was wearing an Apple Watch equipped with medical sensors and experimental software to track basic functions of his heart. And the watch was worried. It had, according to the display, detected signs of an irregular heartbeat.

    Before long, Foley was in an emergency room, where doctors hooked him up to an ECG(心电图), which showed that he was in atrial fibrillation(心房颤动), an irregular heartbeat that can lead to blood clots(血栓), stroke and other potentially disastrous diseases. Foley spent the next few days in the hospital while doctors worked to return him to a normal heart rhythm eventually turning to a procedure called electrical cardioversion to shock his heart back to normal. Foley is doing fine now. But he believes that, if not for the warning on his watch, he might not have sought help in time. “I would have never known,” he says.

    Foley and his watch were part of an experiment run by Apple and Stanford's medical school. But beginning Dec. 6, anyone can get an on-the-fly heart checkup, assuming they've paid $399 or more for an Apple Watch. That's when Apple will launch a software update that turns its latest model, called the Series 4, into a personal ECG, thanks to an innovative new sensor. Though less complicated than hospital ECG machines, the watch version can still provide basic information and warnings of potential risks worthy of a closer look by a medical professional.

    For Apple, this new ECG-on-your-wrist is its biggest bet yet that personal technology will inevitably include personal health. Along with competitors, Apple has already offered fitness functions, such as apps to track the steps you've walked. But with the new ECG scan, Apple is moving straight into medical aspects of heath, a distinction underlined by the fact it sought and received Food and Drug Administration clearance for the clearance for the heart monitor.

    A team of engineers at Harvard University in trying to create the first robotic fly. Designed to do what a fly does naturally, the tiny is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

    "The added difficulty with a project like this is that actually none of its components is off the shelf and so we have to develop them all on our own' said Robert Wood, a Harvard engineering professor.

    They engineered a series of systems to start and drive the robotic fly. "The seemingly simple system which just moves the wings has a number of interdependencies (相互依赖）on the individual components, each of which individually has to perform well, but then has to be matched well to everything it d connected to," said Wood.

    While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers' fields or on the battlefield. "Basically it should be able to take off, land and fly around," he said.

    Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications." You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animal, but using these robots instead" he said. "So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day-to-day basis."

    People can't see you when you're speaking on the phone, but they can hear you. So, the way you speak is especially important. In fact, researchers have calculated that 80% of communication over the phone is through your tone of voice; and only 20% is from the words you use. Here are our top tips on how to speak over the phone.

    ①Facial Expressions

    Your facial expression can influence your voice. For example, if you smile, your voice will sound warm and friendly, just the opposite, if you have an angry look on your face, it can make you sound unpleasant.

    ②Volume

    If you speak too loudly, you could sound angry. And if you speak too softly, it'll be difficult to hear you. So, speak loudly enough to be heard clearly, but not so loud that you're shouting.

    ③Pace

    The pace of your voice is how quickly you speak. And this can show how you feel. For example, an angry person might speak faster than normal. Or a downhearted person might speak very slowly. Try speaking a little more slowly than normal. This will make you sound confident, and it'll make it easier for the other person to understand you.

    ④Gestures

    Gesturing can influence the tone of your voice. When you gesture, you bring more air into the lungs, which can make your voice sound warmer. Gestures are also useful to help you stress the right words or even find the words you need. The best thing about gesturing during a phone call is that no one can see what you're doing, so you can gesture as wildly as you like!

    ⑤Movement

    If you're feeling nervous, stand up and move around. It will reduce the nervousness in your body and help your voice to sound more confident.

    ⑥Pauses (停顿)

    Using pauses every now and then can help you to slow down. This will make you sound more confident and in control. Also, if you pause after giving some new information, it'll give the other person time to understand it. At the same time, listen to how the other person uses pauses. They could tell you something about the speaker's feeling. For example, when a speaker is really angry, he might use pauses and says, "I…am…so…angry…"
