It should come as no surprise that the more stressed parents are at work, the greater the burden on their family is. 1. After all, the more time parents spend working, the less time and energy they have to plan and prepare healthful meals.
For years, most studies have focused on the role of working mothers while fathers were ignored. They didn’t look at the family as a whole.2.It adds a new wrinkle to the relationship between work stress and family nutrition.
Moms’ work related stress is still a central factor in how well families eat because they typically do most of the food shopping and cooking. 3.The study found that when mom or dad experience high levels of work related stress, their families are eating one-and-a-half fewer family meals per week, and the parents themselves report eating fewer fruits and vegetables, more fast food, and are less likely to eat breakfast regularly.
It’s worth noting that the study looked mainly at low income families who belonged to ethnic or minority groups.4. But the implications are wide ranging.
5. Teaching kids, especially teenagers, to help with grocery shopping and to cook actual meals, instead of just putting a frozen pizza in the microwave, could be an important piece of the puzzle in helping families improve their eating habits.
A.But dad’s work related stress has a large impact, too.
B.As to family nutrition, the entire family plays a role even kids.
C.Yet, the kids’ stress may affect the families’ nutrition, too.
D.So the findings don’t necessarily apply directly to other types of families.
E.It’s also probably not a surprise that this can negatively affect a family’s nutrition.
F.However, a recent study does and looks at the role of fathers in particular.
G.It is parents who give their kids a good model to develop a good eating habit.
The other day, I bought an expensive anti-aging cream that promised to make my face look several years younger than other women by fighting free radicals(自由基). It made me curious about what free radicals are. Is the anti-aging cream the only way I need to protect myself?
“As a scientific term, free radicals are essentially unstable atoms, ” says Arizona-based doctor, Natasha Bhuyan, M. D. “In medicine, they cause cells to break down over time and are linked to aging. ”
A super simple chemistry review for you：Atoms from different elements are the building blocks that make up water, nitrogen and more. Electron(电子) are the negatively charged atoms, and they like to be in pairs. When an electron loses its partner, it creates a free radical, which is usually unstable and highly reactive. Free radicals typically go through the body to seek out a replacement for their missing electron, and that can result in damage to cells, proteins and DNA.
So how do free radicals form and why do they happen? Bhuyan says, “Scientifically, free radicals are unpaired electrons that are seeking a mate to bond with. The theory behind free radicals is that they can lead to the imbalance between free radicals and antioxidants(抗氧化剂). ” Another mini-science lesson for you：Antioxidants are natural or man-made matters that can help delay or prevent some types of cell damage. They’re often found in fruits and vegetables.
A lot of the aspects of modern life--our diet, lifestyle and environmental factors like pollution, can cause oxidative(氧化的) stress. Over time, oxidative stress weakens cells and tissues and can leave you more easily exposed to certain health issues, including cancer. And, as beauty marketers are keenly aware, oxidative stress can also speed up the aging process. Now that you know free radicals can weak on your health, you’re probably wondering if there are any ways to prevent them from forming or at least to minimize their negative effects.

Japan's biggest airline is betting that the future of travel isn't traveling at all. For the last month, a married couple has been interacting with a robot—called an Avatar—that's controlled by their daughter hundreds of miles away. Made by ANA Holdings Inc., it looks like a vacuum cleaner with an iPad attached. But the screen displays the daughter's face as they chat, and its wheels let her move about the house as though she's really there.
“Virtual travel” is nothing new,of course.Storytellers, travel writers and artists have been stimulating the senses of armchair tourists for centuries. It's only in recent decades that frequent, safe travel has become available to the non- wealthy.
Yet even as the world's middle classes climb out of the armchair and into economy-class seat, there are signs of a post-travel society emerging. Concerns about environmental sustainability cause loss to airlines which release much carbon. And the aging of abundant societies is both restricting physical travel and creating demand for alternative ways to experience the world. For the travel industry, virtual reality offers an attractive response to these trends.
Of course, new technologies encourage far-out claims. ANA doesn't plan to start selling Avatars until next year. Profits, too, will probably be difficult to make: By one estimate, the global market for this kind of technology will be worth only about $300 million by 2023. By contrast, ANA's traditional travel business brought in more than $19 billion last year.
But if the business value for virtual vacations is still weak, the market for technologies that bridge physical distances between families and coworkers seems likely to only expand. ANA's robots may not replace its airplanes any time soon, but they ll almost certainly be a part of travel's high-tech future.
1.Why does the author use the example of a couple interacting with a robot?
A.To show the Japanese are crazy about travel.
B.To indicate virtual travel begins to enter people's real life.
C.To show the couple are very enthusiastic over robots.
D.To express the close relationship between the couple and their daughter.
2.Which of the following is the possible reason for virtual travel's appearance?
A.Storytellers, travel writers and artists have been using it for centuries.
B.Frequent and safe travel has become available to the ordinary people.
C.People are worried about the air pollution caused by airlines.
D.More and more people lose interest in travel.
3.What can we learn about Avatars from the last two paragraphs?
A.They will be put on the market soon.
B.They will bring ANA a lot of money,
C.They will replace ANA's airplanes soon.
D.They are almost unavoidable in travel's future.
4.What can be a suitable title for the text?
A.Your Next Travel May Be Virtual
B.Easy Travel in the Future
C.Virtual Travel Benefits
D.Air Travel Disappearing
America’s latest superhero Austin Perine, who calls himself President Austin, is now taking the country by storm. But he is not a typical superhero. Two things set him apart: He doesn’t fight human enemies, but hunger and homelessness. Also, he’s only four years old.
Our superhero’s origin story started from the day when TJ Perine, his father, took Austin to the Firehouse Ministries, a local shelter that provides housing, food and other services for the homeless. As they drove by the building, they saw a group of 25 homeless men standing on the street corner. That day, Austin used his allowance to buy each man a sandwich and handed the food out himself with his slogan, “ Don’t forget to show love!”
After he returned every week for five weeks in a row, word of Austin’s kindness spread through social media. Austin and TJ could feed 25 to 50 people at a time before, and now, thanks to community support, they can feed 800 to 2,000 people.
But Austin isn’t merely filling stomachs. He has been improving the lives of the homeless people he meets. On that first trip to Firehouse Ministries, TJ and Austin talked to a poor man named Raymont. The respect Austin showed for him touched 41-year-old Raymont, who regained his confidence in life and finally found a job with the help of TJ. All that was made possible because a little boy took the time to care.
Austin’s passion has become his family’s calling. After raising money through a GoFundMe page, Audrey, TJ’s mother established the nonprofit Show Love Foundation, dedicated to fighting homelessness. She now serves as president, and TJ oversees public relations for the foundation full time. They offer medical and mental health care as preventive steps against homelessness.
