3 . Is It Worth Buying Organic Food?

Organic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers have been willing to pay up to twice as much for goods with organic labels (标签). However, if you think paying a little more for organic food gets you a more nutritious (有营养的) and safer product, you might want to save your money. A study led by researchers at Stanford University says that organic products aren’t necessarily more nutritious, and they’re no less likely to suffer from disease-causing bacteria, either.

The latest results, published in the Annuals of Internal Medicine, suggest that buyers may be wasting their money. “We did not find strong evidence that organic food is more nutritious or healthier,” says Dr. Crystal Smith-Spangler from Stanford. “So consumers shouldn’t assume that one type of food has a lower risk or is safer.”

For their new study, Smith-Spangler and her colleagues conducted a review of two categories of research, including 17 studies that compared health outcomes between consumers of organic against traditional food products, and 223 studies that analyzed the nutritional content of the foods, including key vitamins, minerals and fats.

While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were too small, and the researchers were unwilling to make much of them until further studies confirm the trends.

Organic food is produced with fewer chemicals and more natural-growing practices, but that doesn’t always translate into a more nutritious or healthier product. The U.S. Department of Agriculture (USDA) states that “Whether you buy organic or not, finding the freshest foods available may have the biggest effect on taste.” Fresh food is at least as good as anything marketed as organic.

4 . I live in Xizhou in Yunnan Province, on the historic Tea Horse Road. I have to admit that when I first heard that Paul Salopek was going to walk the entire globe on his own two feet, I was blown away. I couldn’t imagine that there could be such an unusual person in the world.

Last May, I met Paul. He told me that it was his first time in China. He talked to me with great excitement about the history, migrations, and discoveries in my region of China. He spoke of the Shu-Yandu Dao (the Southern Silk Road), the travels of the 17th-century Chinese explorer Xu Xiake, the Tea Horse Road and the early 20th-century American botanist Joseph Rock. He also talked of Xuanzang. Paul considered many of them heroes and in a sense Chinese pioneers of slow journalism.

I decided to accompany Paul on his walk toward Yunnan. On September 28, 2021, we set out. Our days were simple: walk, eat, sleep, and repeat. We woke up at sunrise, set off in high spirits, and rested at sunset, dragging ourselves into exhausted sleep.

We met many people on the road. Some were curious, surrounding us and watching us; some gave us directions; some invited us into their home to take a rest; some spoke of the charm of their hometown. We met many beautiful souls, simple souls and warm souls. We were walking with our minds.

Together, we were impressed by the biodiversity of the Gaoligong Mountains. As I walked on ancient paths through mountains, I seemed to hear the antique voices of past travelers urging me to be careful on the road.

Looking back on the more than 200 miles I walked with Paul, I came to a realization. Walking for its own sake, while healthy and admirable, is only a small part of the benefit of moving with our feet. A deeper reward is rediscovering the world around us, shortening the distance between each other, and sharing each other’s cultures.

5 . Parents often believe that they have a good relationship with their teenagers. But last summer, Joanna and Henry noticed a change in their older son. Suddenly he seemed to be talking far more to his friends than to his parents. “The door to his room is always shut,” Joanna noted.

Tina and Mark noticed similar changes in their 14-year-old daughter. “She used to cuddle up (依偎) against me on the sofa and talk,” said Mark. “Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a little girl and sometimes like a young lady. The problem is understanding which time is which.”

Before age 11, children like to tell their parents what’s on their mind. “In fact, parents are first on the list,” said Michael Riera, author of Uncommon Sense for Parents with Teenagers. “This completely changes during the teen years,” Riera explained. “They talk to their friends first, then maybe their teachers, and their parents last.”

Parents who know what’s going on in their teenagers’ lives are in the best position to help them. To break down the wall of silence, parents should create chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental (思想的) break, for children also need freedom, though young. Another thing parents should remember is that to be a friend, not a manager, with their children is a better way to know them.

“Why, yes! It’s mine,” replied Mrs. O’Brien with a ____ smile and shining eyes. “It was given to me by my father years ago. Thank you so much for returning it. May I offer you a reward for your ____?”

“No, ma’am,” he said. “My grandmother says that a good deed is its own reward.”

“Well, that’s ____ what my father used to say. What is your name, young man?”

8 . When I was a boy growing up in New Jersey in the 1960s, we had a milkman delivering milk to our doorstep. His name was Mr. Basille. He wore a white cap and drove a white truck. As a 5-year-old boy, I couldn’t take my eyes off the coin changer fixed to his belt. He noticed this one day during a delivery and gave me a quarter out of his coin changer.

Of course, he delivered more than milk. There was cheese, eggs and so on. If we needed to change our order, my mother would pen a note — “Please add a bottle of buttermilk next delivery” — and place it in the box along with the empty bottles. And then, the buttermilk would magically (魔术般) appear.

All of this was about more than convenience. There existed a close relationship between families and their milkmen. Mr. Basille even had a key to our house, for those times when it was so cold outside that we put the box indoors, so that the milk wouldn’t freeze. And I remember Mr. Basille from time to time taking a break at our kitchen table, having a cup of tea and telling stories about his delivery.

There is sadly no home milk delivery today. Big companies allowed the production of cheaper milk, thus making it difficult for milkmen to compete. Besides, milk is for sale everywhere, and it may just not have been practical to have a delivery service.

Recently, an old milk box in the countryside I saw brought back my childhood memories. I took it home and planted it on the back porch (门廊) . Every so often my son’s friends will ask what it is. So I start telling stories of my boyhood, and of the milkman who brought us friendship along with his milk.

10 . My parents ran the Pagonis restaurant, a small eatery in Charleroi, Pennsylvania, and my first real job, when I was six years old, was shining diners’ shoes. My duties increased as I grew older. By the age of ten I was clearing tables and working as the janitor(清洁工). Dad beamed when he told me that I was the best “mop guy” he’d ever had.

Working in the restaurant was a source of great pride because I was pitching in for the good of the whole family. But my father made it clear. I had to meet certain standards to be part of the team. I had to be responsible, hard-working and polite to the customers.

Except for the shoeshine job, I was never paid for any work I did at the restaurant. One day I made the mistake of telling Dad I thought he ‘should give me $10 a week. He said, “Okay, then how about you paying me for the three meals a day you eat here? And for the times you bring in your buddies for free sodas?” He figured I owed him about $40 a week. This taught me that when you negotiate, you’d better know the other side’s arguments as well as your own.

I remember coming home to Charleroi after being away in the Army about two years. I had just been promoted to captain and was full of pride as I walked into my parents’ restaurant. The first thing Dad said was, “It’s the janitor’s day off. How about you cleaning up tonight?”“I can’t believe this!” I thought. “I’m an officer in the United States Army!” But it didn’t matter. As far as Dad was concerned, I was just another member of the team. I reached for the mop.

Working for Dad had taught me that loyalty to a team comes first. It doesn’t matter whether that team is involved in a family restaurant or in the Army.
