Sidewalks in Chicago were packed during the rush hour. I marched along as quickly as I could. If I didn't get to the station fast I would miss the early train out of the city. That meant even less time to spend at home with my baby.

    On my left was Saint Peter's Church. I'd passed it on the way to the station many times, but today I stopped. Other commuters (使用月票乘车者) rushed around me. I knew I should follow them since my train wouldn't wait. But I had the strangest compulsion to go into the church instead. I hesitated for a moment, but the feeling was strong. I went inside.

    I sat down in a comer. It seemed like ages since I'd sat down to think. Mary Ellen had been born in October, on the very date of her due date, in fact, October 16. A month before my husband, Rick, had lost his job. I often worked as a designer, but I'd planned on taking time off after the baby was born. With Rick out of work, I didn't have the choice. One of us had to find a job fast. I was lucky to find the job I had now. Unfortunately, it wasn't one I could work on at home. Every day I had to take the train into Chicago, a two-hour commute in both directions. I left the house so early and came home so late, so I felt like I barely got to see my baby.

    I was grateful that Rick was at home caring for her, but it was not her mother. Every minute away from her I felt like I was abandoning her.

    Looking around at the windows, I remembered when Rick and I bad first decided to try for a baby. My friend Renee was almost as excited as I was when I told her about it.

    “I've got something for you,” she said one afternoon when I her for lunch. She pulled a medal out of her purse.

    “Fix this to your clothes every day,” she said. “You'll have a baby in no time.”

    Not long after I learned I was pregnant, I was thrilled at first. But little by little I started to worry: Was my baby okay? What if something happened? The doctor assured me things were going smoothly. My family gave me support. Rick tried to encourage me. I even continued to wear my medal. But no matter what anyone said, I couldn't shake off my worries.

    Now that Mary Ellen was born I had new worries about motherhood. Is this how life was going to be from now on, with every stage of my child's life bringing new fears and anxieties?

    I thought of Renee and her gift of the medal, feeling hopeful. On my way to the door I stopped at the gift counter. I'd missed the early train, so there was time to look around. I went over to a box full of angel cards, thinking of Renee. So many things could happen in the future as Mary Ellen grew up, went to school and went out on her own. So many things to worry about. It would take an army of angels to cover them all.

    I saw a familiar face in the box. It almost felt like I was looking at a friend, someone who cared about my baby as much as her father and I did: On the back of the card was a date. “October sixteenth?” I said, not believing my eyes.

    “That's the angel's birthday,” the woman at the counter told me. I nearly burst out laughing right there. Mary Ellen's birthday! Maybe I couldn't be with Mary Ellen every minute. But never again would I worry that she was out of the angers protection, or doubt that she had a special friend.

    Should you work out in the gym in the morning instead of in the evening? It all depends. Of course, there are advantages of working out(运动) in the morning.

    You will increase your energy for the rest of the day. “Morning workouts result in better energy levels throughout the day and give you more mental sharpness,” says Dr. Cedrie Byrant, Chief Science Officer of the American Council on Exercise.

    Here is another advantage. In 2017, health researchers found that exercising in the morning helps you sleep better at night. According to the study, in all cases, those who exercised at 7:00am experienced about a 10 percent drop in blood pressure that carried through the rest of the day. They also had about a 25 percent drop in blood pressure at night, slept longer and had more beneficial sleep cycles than when they exercised at other times of the day.

    However, there are disadvantages, too.

    If you are not an early riser, getting out of the bed in the morning can be very difficult. Byran says that if you're not used to exercising in the morning and force yourself to get up, you may not put as much effort into the exercise as you would later in the day. Also, if you aren't careful, you can damage your sleep schedule, which can lead to insufficient sleep.

    Besides, hitting the gym before work can cause a challenge in terms of scheduling. If you work a 9-to-5 job, getting ready for work and going to work can cut your morning workout short, Byrant notes.

    To sum up, it has both advantages and disadvantages. If it suits you better to work out in the morning, you can do so.

    It has been around for centuries, but up until very recently, traditional Chinese medicine (TCM) wasn't fully accepted abroad. Proof of this can be found in The Treatment (《刮痧》), a 2001 film that tells the story of a Chinese man in the US who's accused of abuse after he uses guasha, a form of TCM treatment, to cure his grandson's disease.

    During the last 10 years or so, however, TCM has been getting increasingly popular all over the world. A report released by the State Council Information Office on Dec. 6 says this style of health care, which includes different forms like herbal medicine and exercise, has spread to 183 countries and regions.

    "We have set up 10 TCM centers outside China, and all of them are popular among locals," Wang Guoqiang, head of the State Administration of Traditional Chinese Medicine, said at a news conference on Dec 6. "Governments of 86 countries and regions have signed agreements with the Chinese government on TCM corporation."

    One of the reasons behind the growing popularity of TCM is the increase of scientific research into it. And after Tu Youyou, the Chinese scientist who discovered the anti-malaria (抗疟疾) drug qinghaosu (青蒿素), won the Nobel Prize in 2015, TCM became even more famous internationally.

    However, all these achievements in TCM don't mean that it's problem-free. Over the years, TCM has faced challenges in being able to prove that it has certain effects.

    Some researchers have suggested TCM should be more exact and work together with Western medicine.

    "Bringing together with Western medicine and TCM, rather than being in competition, is where the potential for great effects is," said Bernhard Schwartlander, the China representative of the World Health Organization.

    When Joanne Morton and Lydia Shaw came across the Boston Public Market, which features only New England businesspersons, they knew they had to stop in. The women, visiting from southeastern Connecticut, always try to buy local. "We always try to support our local farmers and businessmen," says Ms. Shaw. "We're not into big companies," adds Ms. Morton.

    They aren't alone. A great number of Americans continue to be attracted by "local" food and to buy it, according to recent surveys from the International Food Information Council Foundation, the Pew Research Center, and British polling firm Ipsos. But what does it mean to shop local? For some, local is still a matter of geography. For others, it is about supporting their local economy (经济). And for still others, it is about knowing where their food comes from and how it is made, even if it is coffee shipped from a Costa Rican company. In 2008, Congress passed a bill that gave money to support local food. According to the Food, Conservation, and Energy Act, a product that can be considered local has to travel less than 400 miles.

    But Lydia Zepeda, a professor at the University of Wisconsin-Madison, has found the largest agreement about what is local is any product that comes from within an hour's drive. "But is that with or without traffic?" She asks. "What if it crosses state lines?" adds John Hayes, a food science professor at Pennsylvania State University. "A customer might like to buy local to help an old town," he says. "Or maybe it's just because local food tastes better." It is for Kaitlin Bohon. "I taste a difference," she says at the Boston Public Market. For Ms. Bohon, buying local is both about supporting New England business and knowing who grew and handled her food.

    Amsterdam is one of the most popular travel destinations in the world, famous for its beautiful canals, top art museum and cycling culture.

    Money Saving Tips

    • Unless you really want to see the tulips (郁金香) blooming, avoid booking between mid-March and mid-May. This is when hotel and flight prices rise sharply.

    • Look for accommodations in Amsterdam's South District, where rates are generally cheaper than in the city center.

    • Buy train tickets at the machine instead of the counter to save a bit of money.

    • Check out our homepage to view price comparisons for flights, hotels, and rental cars before you book.

    A young woman turns around and around quickly, and jumps high. In the background, a young girl reads a rejection (拒绝) letter from a ballet school. "You have the wrong body for ballet," it says, "and at thirteen, you are too old." This was one of the most popular advertisements (广告) of 2014 and it describes American ballet Theatre's principal (主要的) dancer Misty Copeland.

    This was not a real letter. But Copeland says it is very similar to letters from her childhood. While many dancers start at the age of three. Copeland only began to study ballet in 1995 as a thirteen-year-old.

    People often told her that she was too old, or that she didn't have the perfect body type (She is only 157 cm tall). Her family moved a lot, and it was sometimes difficult for her to attend ballet classes. But Copeland loved dancing and did not want to give up. She stayed with her ballet teacher during the week and spent time with her family only at the weekend. This was a difficult life, but she worked hard and won her first national competition when she was fourteen years old. Copeland joined the American Ballet Theatre in 2000 and performed in many ballets over the next few years. In 2007, she became a solo (单独的) performer, and in 2015 she became its principal dancer.

    Copeland is now a dancer, author and Broadway performer. She also stars in the 2015 film A Ballerina's Tale. So what's next? According to Copeland, anything is possible: "My career (职业) really is just now beginning."
