After suffering through many months of unemployment  (失业). my wife and I moved this week from Colorado to Ohio. where she was starting a new job. Not knowing anybody there. we were pretty concerned about how we'd get our entire home unloaded (卸下) without killing ourselves.

    We made a phone call to hire (临时雇用) a couple of college students to help with all the heavy lifting once we got there. But one neighbor after another stopped by to help us. What ? Have we moved to some other country ? Maybe we've died and gone to heaven!     

    Unloading actually became fun and joy because there were so many wonderful new friends to help when we worked. The more people helped. the easier the work became. We were afraid the job might take days for the two of us alone. but it was finished in a few hours. Many total strangers would either walk by the sidewalk or drive by to ask us if we were moving in. Many were happy that this old house that had sat empty for so long was coming to life again. We were invited to an outdoor meal yesterday by neighbors on the same street.

    All the time. my brain was resting on this new sense of hope that people can be so friendly to strangers. Among all the conversation were lots of offers to help each other in all kinds of ways. It's wonderful to live in such a kind little town. I feel so grateful to be here. and wish the rest of the world could see how an entire community can model  (做榜样) what it's like to help each other.

How to improve your vocabulary

    Vocabulary is a key part of learning a new language. {#blank#}1{#/blank#}  Maybe you can't learn a hundred new words a day, but you can learn one or two a day, totaling thousands of new words over the years. Here are some tips for building up your vocabulary.

    Make a plan to learn new words. If you want to improve your vocabulary more quickly, you have to make at least a small promise. {#blank#}2{#/blank#}

Make you vocabulary practical（实用的）. {#blank#}3{#/blank#} For example, learn more of your trade language—- the words that are commonly used in your business or hobby or vocation(职业). Find better, fresher, clearer words to express what your friends are talking about.

    {#blank#}4{#/blank#} As you read, if you come across a new word that you don't understand. Don't miss it. Take the time to look it up in a dictionary. Write it down and use it later.

    When you learn a word, use it immediately and frequently. Put your new word into conversation with as many different people as you can. {#blank#}5{#/blank#} Use it in sentences. Write it on a card and practice it while waiting for red lights.

A. Repeat it to yourself.

B. They're highly reusable

C. Start learning where you are.

D. Decide to learn one new word every day or two.

E. When you're writing something, use a dictionary frequently

F. Start by learning the words that can express what's most important to you.

G. The more you read, the more words you'll see, and the more you'll understand.

    India has many festivals, with some celebrations that last for weeks. However, none of them come even close to Holi, India's most colorful and fun festival. Celebrated on the day following the full moon, this year's festival happens to be on March 19th.

    As with most Indian festivals, this one also has many different folk stories. Most of them center around the success of good over evil. The most popular one is about a king, who hates his son Prahlada for loving the creator of the Universe－Lord Vishnu. When every attempt to stop him fails, his sister, Holika believed to be immune (免疫的) to fire, joins in the effort by inviting the young boy to sit with her inside a huge fire. Helped by the power of Lord Vishnu, Prahlada escapes safely, while the evil Holika is burned to death. To remember this event, huge outdoor fires are lit in the night before Holi in order to clean the air of evil spirits and to celebrate the death of the evil.

    So what's so great about this day? While there are some fun parades (游行) and folk songs and dance performances, the most fun of all is walking to the streets and splashing (泼洒) people with water guns and dry colors and even covering them with entire buckets of colored water. On this day, everybody is fair game, no matter how old or how young.

    At about midday, the splashing comes to an end and people living close to oceans or rivers usually take a bath in the water to clean themselves before going home to a delicious home­made big dinner and a well­deserved short sleep, following this full day of fun and activities.

    Advances in artificial intelligence and the use of big data are changing the way many large companies recruit (招募) entry level and junior management positions. These days, graduates' CVs may well have to impress an algorithm (算法) rather than an (human resources) manager.

    While algorithms supposedly treat each application equally, experts are divided about whether so-called robo-recruitment promises an end to human prejudice in the selection process —or whether it may in fact add to it.

    “AI systems are not all equal,” says Loren Larsen, chief technology officer for HireVue, which has developed an automated video interview analysis system. “I think you have to look at the science team behind the work,” says Mr Larsen.

    The problem, experts say, is that to find the best candidates an algorithm has first to be told what “good” looks like in any given organization. Even if it is not given criteria that seem discriminatory, a powerful machine-learning system will quickly be able to copy the characteristics of existing workers. If an organization has favoured white male graduates from well-known universities, the algorithm will learn to select more of the same.

    The growing dependence on automation to judge suitability for everything from a loan to a job worries Yuriy Brun, an associate professor specializing in software engineering. “It takes a lot of the time for a company to put out software but it doesn't know if it is discriminatory” he says. Prof Brun explains that, considering the use of big data, algorithms will unavoidably learn to discriminate.

    Many of those working with robo-recruiters are more optimistic. Kate Glazebrook, the leader and co-founder of Applied, a hiring platform, says her task is to encourage hiring manager to move away from such indicators of quality as schools or universities and move to more evidence-based methods. When candidates complete tests online, Applied hides their names and shows the tests the candidates have completed, question by question, to human assessors. Every stage of the process has been designed to remove prejudice.

    With the same aim, Unilever decided in 2016 to switch to a more automated process for its graduate-level entry programme. Unilever worked with HireVue, Amberjack, which provides and advises on automated recruitment processes, and Pymetrics, another high volume recruitment company, which developed a game-based test in which candidates are scored on their ability to take risks and learn from mistakes, as well as on emotional intelligence. Unilever says the process has increased the ethnic diversity of its listed candidates and has been more successful at selecting candidates who will eventually be hired.

    “The things that we can do right now are impressive, but not as impressive as we're going to be able to do next year or the year after,” says Mr Larsen.

    Still, robo-recruiters must be regularly tested in case prejudice has occurred without anyone realizing it, says Frida Polli, the leader and co-founder of Pymetrics. “The majority of algorithmic tools are most likely causing prejudice to continue existing. The good ones should be examined.”

    When I was younger, I thought that boys and grown men should not cry. The tears were signs of being weak and a sissy(胆小鬼), which a man is not supposed to be. This was even strengthened in my young mind when the song, Boys Don't Cry, came out in the early 1980s.

    But just this June, I discovered that courage is not all about trying to keep all the pain inside in check. Courage is not all about trying to hide the tears. It is the opposite — the tears strengthen the heart's courage. And I saw this in my father. That day my father cried.

    My 18-year-old sister eloped (私奔) and from it I saw how weak my father's heart was. My sister and I were used to seeing him as an iron-willed figure and authoritarian father.

    For three days after my sister eloped, he would not talk. He would just sit quietly outside our house in the dark. On the fourth night, I sat beside him and asked him to tell me what he felt about everything.

    It has been years since I have laid my hand on my father's shoulder as we have drifted apart (疏远) farther and farther while I was growing up. That night，though, I sensed my father trying to control his pain and I wanted him to be able to let it out. We have all cried over what happened except him. All of us except him.

    The simple touch and my words, "Dad, it is not your fault.", broke my father's dam.

    In the darkness, he began to cry. I felt his shoulders shaking as he whispered, "Where did

    I go wrong? All I ever wanted was for my children to grow up right. Why couldn't your sister wait?"

    I understood then why he preferred to be in the dark. By being there, he hoped to spare his family of a father's pain. His tears, though we did not see them before that night, were there all the same. I saw his courage, that night when my father cried with my hand on his shoulder, and understood his pain.
