It's a sad reality that many of us find ourselves just too busy to contribute to our communities. For a long time, I, too, believed it cost too much in time, money and 1 to make a real difference. But all that changed when I 2 my good-deed-a-day project.

My daughter, Emily, was my primary 3 . I wanted to show her we could do little things to help others, and be happy.

The first week, I wasn't sure if I could 4 it. I surfed the Internet for ideas. One day, I 5 a blind man in the subway station. He smiled as he thanked me. Another day, I brought flowers from my garden to a local nursing home... I could only hope I was arousing 6 in others.

Luckily, after just a few days I found it easier than I'd expected. I knew I was making a 7 .

Every evening at the dinner table, I 8 that day's good deed to Emily. Emily began copying what I'd started. On a walk home from school, she marched over to a neighbor's pot of geraniums(天竺葵), which had toppled(摇晃) in the wind, and set it 9 . "That was my good deed for the day!" she yelled. Another day, she helped me collect 10 from our neighbors for the food bank. We dropped off the food and,11 we drove away, Emily announced 12 that she wanted to work there one day.

By the last week, I knew I'd changed. At first, I hadn't been entirely13 that I could do a good deed every day. Now it was practically second 14 . I felt a greater responsibility to take action when I saw a need, 15 looking the other way. I felt as though I'd awakened, somehow.

As much as 80 percent of premature heart disease is preventable by making specific lifestyle choices.But others may not have crossed your mind. "A small change in your everyday routine can potentially have a big impact in the long run," says preventive cardiologist Dr. Beth Abramson.

●Get eight hours of sleep.

"When you're not rested, everything that happens in your life is a lot more stressful," says Dr. Arya Sharma, a professor of medicine at the University of Alberta. If we're sleep deprived, our bodies also have more difficulty controlling blood pressure, inflammation and glucose levels.

●

Doing good for others helps your self-esteem and relieves stress. Research published in Psychosomatic Medicine in 2016 showed that a feeling of purpose in life is linked to a lower likelihood of heart attack and stroke. "We know that loneliness is a risk factor for heart health," adds Sharma. "Volunteering gets you out of the house and creates a social network."

●Avoid polluted air.

Exposure to this kind of pollution over time raises your risk of heart disease. Inhaling contaminants formed from chemicals like Sulphur (硫) dioxide, carbon and nitrogen oxides may irritate arteries (动脉) and increase inflammation.Try to get your outdoor exercise far away from highways and industrial districts, and spend more time indoors when the air quality index is poor.

●Eat breakfast.

A recent study in the Journal of the American College of Cardiology found that healthy people who skipped breakfast were almost three times more likely to have heart disease six years later than those who partook in a substantial morning meal. According to Abramson, you need to eat a balanced diet as part of a healthy lifestyle.If you're eating a proper breakfast, you're less likely to be hungry later and make poor food choices.

A．Be social and outgoing.

B．Engage in voluntary work.

C．There are physiological effects of this condition on the body.

D．Choose whole-grain, low-fat breakfast foods and include fruit.

E．These factors can all have an impact on cardiovascular (心血管的) health.

F．Some strategies, such as exercising and managing weight, are well known.

G．Even short periods of exposure are unhealthy for people with other health risks.

Many green plants that are used to decorate living rooms and kitchens are marketed as air-purifying. However, scientists largely agree that plants can't do very much to clean an entire room. Now, a Parisian company known as Neoplants is trying to change that by growing genetically modified(转基因的) plants that help remove harmful chemicals from the air.

Its first product, called the Neo P1, is a bioengineered version of the pothos (绿萝). Pothos is characterized by its green leaves and is relatively easy to care for. The Neo P1 is meant to capture and recycle dangerous air pollutants commonly found in homes called volatile organic compounds (挥发性有机化合物VOCs), which are often human-made chemicals. So it's a popular choice for people looking to beautify their living spaces. But the Neo P1 starts at $179, and to purchase one, potential shoppers must first join a waitlist.

The idea of air-purifying plants came from a 1989 study by NASA,in which regular houseplants were tested in two-by-two-foot rooms. When scientists filled these rooms with VOCs, they found the plants could absorb some of the harmful compounds. "Actually, it'd take about ten houseplants per square foot to noticeably improve air quality," Michael Waring, an environmental engineer at Drexel University who wasn't involved with Neoplants, reported in a 2019 study. "Plants, though they do remove VOCs, remove them at such a slow rate that they can't compete with the air exchange mechanisms already happening in buildings," Waring said.

As for Neoplants, its Neo Pl was tested in a 35-liter glass room. In it, the Neo P1's results were 30 times better than NASA's, according to the company—which means it'd still take a large number of them to clean a room. Currently, the company's engineers are designing testing sites that more accurately resemble（与...相似）living spaces. To Neoplants' executives, cleaning the air inside a home is a more logical starting point than trying to filter（过滤）the entire atmosphere.

As climate change causes ocean temperatures to rise, one of Greenland's previously most stable glaciers is now reducing at an unheard-of rate, according to a new study.

The study was led by researchers at The Ohio State University. The team found the truth. Between 2018 and 2021, Steenstrup Glacier in Greenland reduced about 5 miles, thinned by about 20% and doubled in the amount of ice that went into the ocean. According to the study, such a rapid change is so extraordinary among Greenland's ice formations that it now places Steenstrup Glacier in the top 10% of glaciers that contribute to the entire region's total ice discharge.

Steenstrup Glacier is part of the Greenland Ice Sheet, a body of ice that covers nearly 80% of the world's largest island, which is also the single largest contributor to the global sea rise from the cryosphere（冰冻圈），the portion of Earth's ecosystem that includes all of its frozen water. While the region plays a crucial part in balancing the global climate system, the area is steadily reducing as it loses hundreds of billions of tons of ice each year because of global warming.

As far as scientists knew, Steenstrup Glacier had been stable for decades. It was hardly influenced by the rising temperatures that had influenced so many other regional glaciers, likely because of its special position in shallow water. It wasn't until Thomas Chudley, lead author of the study, and his colleagues collected observational and modeling data from previous remote sensing analyses on the glacier that the team realized Steenstrup Glacier was likely experiencing melting due to anomalies（反常现象）in deeper Atlantic water.

According to Chudley, the current situation in Greenland serves as an early warning sign for possible future events in West Antarctica within the next few centuries. He also expressed the importance of conducting direct observations in the fjord(峡湾) to understand the reasons behind the changes observed in Steenstrup Glacier.

Bertha Mahony Miller, a US editor and publisher, was born on March13th, 1882 in Rockport, Massachusetts. After her mother's death, 11-year-old Mahony helped look after her three younger siblings. She entered local teacher-training classes after high school but left the next year to pursue studies at newly formed Simmons College in Boston. Unable to afford the four-year program in library science, she chose instead to take a year of secretarial courses.

In 1906, Mahony became a secretary for the Women's Educational and Industrial Union (WEIU), a nonprofit social-service agency. Board members soon recognized her creativity and intelligence, so she was given a variety of duties. One of her favorites was organizing plays for children, and her interest in children's literature expanded as she searched through books for appropriate material.

With the support of the Union, Mahony opened the Bookshop for Boys and Girls in 1916. The creation of this Boston store devoted to children's books came at a time when most parents, booksellers and publishers did not put much thought into what children read. Mahony aimed to change this by offering a large selection of thoughtfully chosen books and seeking help from many notable librarians such as Anne Carroll Moore and Alice Jordan. Storytelling, author visits and other activities helped spark people's interest in the store, and the creation of a bookmobile extended its reach to other regions.

To coincide with（与...同时举行）the opening of the store, Mahony edited and published a buying guide of selected children's books, the first commercial list of its kind. It grouped some 1,200 books into categories based on age and subject matter and provided a brief description of each publication. The attention it drew led her to another idea. In 1924, Mahony and coworker Elinor Whitney founded The Horn Book Magazine, the first periodical devoted entirely to children. Mahony and Whitney also compiled（汇编）Realms of Gold in Children's Books(1929), a publication covering five centuries of children's literature.

Bertha Mahony Miller devoted much of her life to promoting children's literature. Her efforts enlightened（启发）consumers and encouraged publishers to expand and improve their juvenile (少年的) offerings. She is considered a figurehead of the children's literature movement.
