I am a writer．I spenda great deal of my time thinking about the power of language—the way it canevoke(唤起)an emotion, a visual image, a complex idea, or a simple truth．Languageis the tool of my trade．And I use them all—all the Englishes Igrew up with．

Born into a Chinese family that hadrecently arrived in California, I've been giving more thought to the kind ofEnglish my mother speaks．Like others, I have described it topeople as "broken" English．But I feel embarrassed to say that．It hasalways bothered me that I can think of no way to describe it other than"broken", as if it were damaged and needed to be fixed, as if it lacked acertain wholeness．I'veheard other terms used, "limited English," for example．Butthey seem just as bad, as if everything is limited, including people'sperceptions(认识)ofthe limited English speaker．

I know this for a fact, because when Iwas growing up, my mother's "limited" English limited my perception of her．I wasashamed of her English．Ibelieved that her English reflected the quality of what she had to say．Thatis, because she expressed them imperfectly her thoughts were imperfect．And Ihad plenty of evidence to support me: the fact that people in departmentstores, at banks, and at restaurants did not take her seriously, did not giveher good service, pretended not to understand her, or even acted as if they didnot hear her．

I started writing fiction in 1985．And forreasons I won't get into today, I began to write stories using all theEnglishes I grew up with: the English she used with me, which for lack of abetter term might be described as "broken", and what I imagine to be hertranslation of her Chinese, her internal(内在的) language, and for that I sought topreserve the essence, but neither an English nor a Chinese structure．Iwanted to catch what language ability tests can never show: her intention, herfeelings, the rhythms of her speech and the nature of her thoughts．

    I had arrived at the airport to catch an early flight home.It had been a very busy three days for me on an interstate trip with lots of meetings，business to do and new customers to meet.Then came the announcement that the flight had been delayed due to a technical problem.I could see a group of technicians and ground staff rushing about，obviously trying hard to fix the problem.I watched and listened as many of the passengers sitting near me shared their frustration about the inconvenience.

    As I sat waiting，I reflected on my last meeting for the day.It was not a business meeting but rather a very enjoyable and brief lunch with an old business associate and friend I had not seen for over 12 years，and who I had worked with for nearly 15 years before we lost in touch.I had been given his phone number by a customer I had visited on the first day of my trip，so I called him out of the blue and made a time for us to meet.

    Our lunch was spent recollecting(回忆) times gone by and as well filling each other in on what had happened in our lives over the last 12 years.Our conversation was frequently interrupted with statements such as 'remember when we did...'，'whatever happened to...' and of course the one we all liked to hear...'you know you haven't changed one bit，except for a few more grey hairs.'

    We both laughed and smiled as we recalled the good times and the great experiences we had shared over the 15 years we had worked together. Each event we discussed caused another recollection and everything we talked about centered on the good times.Almost at the same time，right at the end of our time together，we both said how much we both enjoyed it and that we must do it again.We agreed to catch up when I was next in town，then said our goodbyes and I was off to the airport.

    So with this extra time on my hands as I waited for my flight，it was great to revisit and replay in my mind all that we had talked about over lunch.I realized at that moment just how important it is to have regular reminders of the good times in your life and to be able to take the time to recall the past，for so much of what we have done in our past，shapes us and makes us who and what we are today and beyond.

    At the end of my busy trip with the focus on getting all the business done，I was indeed fortunate enough to have had the chance to take a short break and reflect on the good things that had happened in my life over 12 years ago.It was somewhat like looking at an old photo album that you have found stored away in a cupboard in your house.There before your eyes are lots of wonderful memories in print that take you back to that time and place，and most importantly to those people who are in the photos.It also made me realize that when you get caught up doing what has to be done in the moment，it is easy to forget the people you have met in your life who have made a positive effect on and enriched you，often in only the smallest of ways.

    My flight home was finally called nearly three hours later and yes as you would have expected many of the passengers cheered when the announcement was made.I smiled as I boarded the plane and realized that I was not at all upset about the delay，as I had been able to spend much of my time reflecting on the good times from days gone by and now eagerly look forward to many more opportunities to recall the past.

    I've never been the kind of person to say, “it's the thought that counts” when it comes to gifts. That was until a couple of weeks ago, when my kids gave me a present that blew me away.

    For years now, I've been wanting to sell our home, the place where my husband and 1 raised our kids. But to me, this house is much more than just a building.

    In the front room, there's a wall that has hundreds of pencil lines, marking the progress of my children's growth.

    Every growth stage is marked in grey, with each child's name and the date they were measured. Of all the objects and all the memories, it's this one thing in a home that's the hardest to leave behind. Friends I know have returned home after work only to discover their wall of heights has been freshly painted over. A new paint job wouldn't normally be greeted by tears, but erasing that evidence of motherhood hurts more than it should. Our kids grow in so many ways, but the wall is physical evidence of their progress, right there for everyone to see.

    Over the years, I've talked about how much I would hate leaving that wall behind when I moved, even though the last marks were made 10 years ago when my kids stopped growing.

    So one day, while I was at work, my children decided to do something about it.

    They hired Jacquie Manning, a professional photographer whose work is about capturing (捕捉) the beautiful things in life, from clear lakes and skies to diamonds and ballgowns (舞会礼服).

    She came to our house while I was at work, and over several hours, took photos of the hundreds of drawings and lines, little grey fingerprints (手印), and old marks. Somehow, she managed to photograph all those years of memories perfectly. Afterwards, she put all the photos together into one image, transforming them into a beautiful history of my family.

    Three weeks later, my children's wonderful gift made its way to me—a life-size photo of the pencil lines and fingerprints that represents entire lifetimes of love and growth.

    Almost every night for more than 10 years, Kirk Alexander, 48, ordered a late dinner from his local restaurant Domino's Pizza. But for the past two weeks, he hasn't called for even once.

    "A few of my staff mentioned that we hadn't seen his order in a while. Then I found that it had been 12 days since he last ordered, which is not like him," Domino's general manager Sarah Fuller said, feeling she could no longer ignore Kirk's recent absence.

    Sarah has known Kirk since 2009 when she started working at the Domino's Pizza as a delivery driver (送餐员) and often made the short trip to Kirk's home about six minutes away. She knew Kirk worked from home, and neighbors said he seldom left. She also knew that he suffered some health problems in the past. Something, Sarah worried, was wrong.

    Around 1 a. m. on May 8, Sarah sent delivery driver Sean Hamblen to visit Kirk's home. Sean arrived at Kirk's home and knocked on the front door several times. There was no answer. He later noticed that the lights and the TV in the home were on. When he called Kirk's phone, it went straight to voice mail.

    Sean drove back to the restaurant to tell Sarah and they decided to call 911. Soon, officers arrived at Kirk's home. So did Sarah and Sean. They heard a man calling for help from inside. Officers broke down the door and found Kirk on the floor in need of medical attention at once after suffering from a heart attack (心脏病发作). One day later, they might have been too late.

    So is keeping an eye on regular customers (老顾客) part of Domino's business plan? Not really. "Kirk is part of our family here and we feel like we need to do something." Sarah said.

    When your pen is broken, the batteries (电池) in your toys run out, or you have some leftover food, what will you do with these things? You will probably throw them all into one bin. But actually, all of these pieces of rubbish need to be sorted (分类) separately.

    Rubbish sorting is a big problem worldwide. In recent years, some Chinese cities have been working hard on it. Shanghai has worked with Alipay to create a "green account (账户)" service. Account owners get points by correctly sorting their rubbish. Through the Alipay app, they can exchange the points for milk, phone cards or other products. The city is asking all people living there to sort their rubbish into four groups: wet, recyclable, harmful and dry.

    Wet waste is something you don't want but that pigs can eat. Plastics, glass, paper and other things that can be reused are recyclable waste. Harmful waste includes things like medicine, batteries and bulbs. Finally, any waste that's not wet, recyclable or harmful will go in the "dry waste" bin.

    Many other Chinese cities are also sorting their rubbish in this way. For example, Shenzhen has been doing this since 2012. Students there also receive waste-sorting guidebooks that they must study.

    In fact, there are still many workers specially working for sorting rubbish by hand in China. There is still a long way to go. But it's never too late for every Chinese to learn how to sort rubbish properly and protect the environment.

    If you don't sort your rubbish, all of it will go to a landfill (垃圾填埋场) and be buried together.

    These landfills can take up much ground that could be used for planting. The electronic waste you throw away, such as batteries or used mobile phones, can cause pollution. Other pieces of rubbish, like the metal part of a pen, can be used to make other things if they are properly recycled.

    Cao Zhawa has been planting trees for most of his life. He lives and works in the heart of Mu Us Sandyland, an area in the southwest part of Inner Mongolia.

    In 1958, when he was just 16 years old, Cao started planting trees. Cao's trees now cover an area of more than 1.3 million square meters. Cao's forest is worth an estimated 10 million yuan and can produce 100,000 kilograms oxygen, enough to sustain a full-grown adult for nearly a year.

    Mu Us Sandyland is one of the places in China most affected by erosion(侵蚀) and desertification. The amount of annual rainfall ranges from 150 to 300 millimeters, while evaporation(蒸发) between 2,000 and 3,000 millimeters. Cao recalls that his growing-up was troubled by sandstorms. This was one of the factors that motivated Cao to join and stay on the tree-planting program.

    Popularly known as the "Green Great Wall", the project, which is set for completion in 2050, would be a 4, 800-kilometer greenbelt of trees and shrubs(灌木) protecting the area from strong winds and preventing soil erosion. Since the start of the Three-North Shelter Forest Program, millions of people have joined in and become a vital part of the plan.

    However, the tree-planters face a host of challenges, with watering the most difficult among them. "When I was young, the level of groundwater was high," said Cao, "But with less rain, the trees are hard to plant and keep alive."

    Planting trees has also become harder for Cao as he ages. However, he doesn't want to leave the forest in the care of his children, and he insists the land belongs to the government. "When I die, I just want to be buried under the trees," Cao said. "Then I will be with them forever."
