When I walked into the house after school, I found my dad at home.

    "What are you doing home already?" I asked casually.

    "Andrew, I was laid off today," he answered quietly.

    I was sure he was joking. "No, you weren't. Why are you really home?"

    Then I noticed his expression and realized he was telling the truth. My father has always been a hard worker and prided himself on his career. My father's unemployment created many changes in our lives. He was home all day, which meant my bed had to be made, my room cleaned up, and my homework done right after school. I would come home every day to find him at the computer searching for jobs. I began to notice how down he seemed, and how losing his job had affected his self-esteem, though he tried to be optimistic. He asked my brother and me to spend less money. I gave up my allowance, which even though it wasn't much, felt like the right thing to do. I also found a part-time job.

    After several difficult months of searching, my dad decided to go in a totally different direction. He explained that he never wanted to be laid off again, so he was going to start his own business. Day by day, I watched him build it, and I admired how much time and energy he devoted to it.

    One evening I asked if he needed help. "Only if it doesn't interfere（打扰，妨碍） with school," he said, which sounded like a yes.

    I showed up at his office the next afternoon, and most afternoons after that for two months. I always knew he was a hard worker, but watching him in action really influenced me. Although this was one of the worst experiences for our family, it taught me a lot about dealing with adversity. Now I know that through creative problem-solving, I can always find Plans, ask for help, and take risks.

The iPhone, the iPad: each of Apple's products sounds cool and has become a fashion. Apple has cleverly taken advantage of the power of the letter “i” — and many other brands are following suit. The BBC's iPlayer — which allows Web users to watch TV programs on the Internet —used the title in 2015. A lovely bear — popular in the US and UK — that plays music and video is called “iTeddy”. A slimmed-down version(简装本) of London's Independent newspaper was started last week under the name “i”.

    In general, single-letter prefixes(前缀) have been popular since the 1990s, when terms like e-mail first came into use.

    Most “i” products are aimed at young people and considering the major readers of independent's “i”, it's no surprise that they've selected this fashionable name.

    But it's hard to see what's so special about the letter “i”. Why not use “a”, “b”, or “c” instead? According to Tony Thorne, head of the Language Center at King's College, London, “i” works because its meaning has become ambiguous. When Apple uses “i”, no one knows whether it means Internet, information, individual or interactive, Thorne told BBC Magazines. “Even when Apple created the iPod, it seems it didn't have one clear definition,” he says.

    “However, thanks to Apple, the term is now connected with portability (轻便) .”adds Thorne.

    ※Clearly the letter “i” also agrees with the idea that the Western World is centered on the individual. Each person believes they have their own needs, and we love personalized products for this reason.

    Along with “Google” and “Microblog”, readers of BBC Magazines voted “i” as one of the top 20 words that have come to define the last ten years.

    But as history shows, people grow tired of fashions. From the 1900s to 1990s, products with “2000” in their names became fashionable as the year was connected with all things advanced and modern. However, as we entered the new century, the fashion disappeared.

    Temples have existed for thousands of years. They are the proof of cultures and civilization that existed many years ago.

    Gobekli Tepe, Turkey

    Located on a hilltop in southwestern Turkey where it snows a lot in winter, the Gobekli Tepe is considered the world's oldest temple. It is nearly 11,000 years old. There are carvings on the rock statues, mainly of lions, foxes, snakes, cranes and wild ducks, as well as scenes of people hunting. Because heavy snow makes it hard to get to the top of the hill, visitors are not recommended to go there in winters.

    White Temple, Thailand

    Immediately upon entering White Temple, you will realize this contemporary, unconventional temple stands out, even in a country dotted with temples. The White Temple is incredibly different and unique in its architecture, art and design. In fact, it is designed in a very modern way. This temple is all white. It is very hot in summer in Thailand, so going to White Temple in other three seasons is a wise choice.

    Sagrada Familia, Spain

    This symbolic Barcelona building is famously unfinished. It is said to be finished by 2026, but no body believes it. However, visitors believe its incompleteness is part of its charm, which sets it apart from other temples in the world. You will have to wait in a long line if you visit Sagrada Familia in summer holiday. Visitors are not that many in spring and winter.

    Kinkaku-ji, Japan

    This temple is absolutely the most popular one in Japan. Whether you visit during the fall when there are red leaves against the golden wall, in winter when the gold is topped with pure white snow, in spring with cherry blossoms, or in summer allowing you to smell the earthy smell after rain – there is never a bad time to visit this beautiful temple.

    Family sizes are shrinking around the world. In many countries, families are having fewer than two children. Smaller families mean many children now grow up with fewer cousins. This is hard to imagine, as I come from a large extended family with 23 first cousins on one side and 25 on the other.

    Sometimes when I can't sleep, I try to name all my relatives. Of course, almost all of those cousins have married and had children and now their children are having children. With extended families growing so large and spreading so far, get-togethers have nearly become a thing of the past.

    One of the last gatherings on my father's side was at the home of a cousin who has a place in the country on top of a hill. A tent was set up, holding long tables creaking(嘎吱作响) under the weight of fried chicken, potato salad and chocolate cake. A fishing hole waited nearby for the kids. Vehicles poured in from every direction, parking on the drive, the grass, wherever they could find a spot. There was talking and laughing and joking and food.

    While such gatherings had grown infrequent, we were all happy to be together. Although some of us had not seen one another since so-and-so's wedding or somebody's father's funeral, most people were still easy to recognize. Three sisters who sat together all had the same beautiful skin their mother had. The cousin with bright blue eyes who raced her horse as a teenager still had bright blue eyes. An older cousin who gave me piano lessons when I was young and naughty seemed to have forgiven me. We share a gene pool of people who work hard and laugh often.

    It was very dark when the last set of taillights disappeared into the night. As we gathered our things, said our goodbyes and prepared to leave, a cousin called to me saying, "Don't forget where you come from." I never could. And I'd never try.

    Imagine your body is like the house you live in. Every day, your family creates rubbish. The rubbish builds up until it is put out for the weekly garbage collection.

    Now, say you put three bags of garbage out, but because one of the collectors was away sick, only two bags are collected. You take the leftover bag inside to be put out again next week. The following week you put on another three bags, plus the leftover bag from last week. But again, only two bags are collected. Imagine this cycle is repeated over the following weeks.

    This is a simple description of what happens to your body when your kidneys (肾脏) don't work efficiently. Your body is not thoroughly emptied of waste products. Other areas of the body such as blood pressure and red blood cell production are affected and the insidious process that may lead to kidney failure begins.

    It's not uncommon for people to lose up to 90% of their kidney function before developing any symptoms. There may be no warning signs. This makes early detection (诊查)difficult.

    Kidney's main job is to remove toxins (毒素) and unwanted water from our blood. Every day our kidneys clean an average of 200 litres of blood. Kidney failure may be a gradual and silent process, going unnoticed because there is no obvious pain.

    Research shows that more than 35% of the patients requiring dialysis (透析) do not see a kidney specialist before they have to do so. Some risk factors for kidney disease such as age and genetic make-up are out of our control; however, some changes in lifestyle may help prevent kidney damage. Two major risk factors for kidney disease, diabetes (糖尿病) and high blood pressure, have been on the rise over the last few decades. Both conditions are chiefly affected by being overweight and not getting enough exercises, which are the potential (潜在的) risk factors for the kidney disease.

Ken was my best friend for 30 years. I told him I would leave Chicago for Philadelphia to receive a new job there. "What do you mean you're leaving?" Ken asked angrily. "When did you interview for a job in another city? You had never told me before." I explained that was the new company's rule. "Like you couldn't tell me?" he asked. "I thought our friendship meant more to you than that." "I'm sorry," I said. But I would never give up the job because of friends.

Ken and I had met in a church. Then Ken was a college student studying mental health and I was working in a company. I found we both grew up in small towns and struggled for school life. He often volunteered in Thailand during school holidays. And I once worked there for five years. Talking with Keri gave me great pleasure. Gradually, our conversations even involved in deeper subjects, like our dreams.

I was older than Ken. When he married Lee, I gave him advice about marriage. By that time, I was running a television production business, and was under a lot of stress. It was Ken who encouraged me and helped me get through the hard time. He was a great guy. Even so, I didn't change my mind.

Anyway, when leaving Chicago, Ken and Lee had a warm farewell (告别) party. But we didn't talk much later. After September 2012, everything changed. It started with a letter from Ken: Lee had cancer. Unfortunately, I got divorced (离婚) later and everything was a mess.

In February 2013,I flew to Chicago to see Ken and Lee. We talked. I found there was no one I had ever been able to talk to quite like Ken. I needed to be there for Ken in any way I could. This friendship mattered more than work. When going back to Philadelphia, I left my job and bought a plane ticket that would mean a lot to the rest of my life.
