For many of us, summertime means road trips to the beach or mountains, or at the very least some additional dust on the outside of our vehicles. The extra dirt leads us to do one of two things: wash our car in the driveway or head to the car wash. But which choice is better for the environment?
The main concerns with either choice are the amount of fresh water being used and the types of chemicals used to remove the dirt. Both of these concerns can be closely monitored when washing the car at home, says Katy Gresh, spokeswoman for the Southwest Region of the Pennsylvania Department of Environmental Protection. She advises car owners to keep a set amount of water for the entire wash. “You don’t want to leave the water running or use more than you need for the job,” she says. But even following this advice comes with an environmental risk: Washing your car in the driveway gets the dirty water into drains（下水道）.
“Drains are not made for treating waste,” says John Scholmbert, executive director of 3 Rivers Wet Weather. Even when car owners use natural soaps to wash their car, Schombert says they are probably ineffective in breaking down grease (油脂)anyway.
The commercial car wash knows full well the rules regarding wastewater in drains. According to the International Carwash Association (ICA), professional car washes must use special water treatment systems. These processes not only keep the dirty water out of drains and regular water treatment systems, but they also work to reduce water usage at commercial facilities.
As experts point out, cleaning our car at home can use 100 gallons of water. Compare that to self-service car washes, which allow you to use only about 17 or 18 gallons of water. And most full-service car washes average about 30 to 45 gallons of water per vehicle.

But Lee Gray, PhD, of the University of North Carolina, US, has made it his business to examine this overlooked form of public transport. He is known as the “Elevator Guy”.
“The lift becomes this interesting social space where etiquette (礼仪)is sort of strange,” Gray told the BBC. “They are socially very interesting but often very awkward places.”
We walk in and usually turn around to face the door. If someone else comes in, we may have to move. And here, according to Gray, liftusers unthinkingly go through a set pattern of movements. He told the BBC what he had observed.
He explained that when you are the only one inside a lift, you can do whatever you want – it’s your own little box.
If there are two of you, you go into different corners, standing diagonally (对角线地)across from each other to create distance.
When a third person enters, you will unconsciously form a triangle. And when there is a fourth person it becomes a square, with someone in every corner. A fifth person is probably going to have to stand in the middle.
New entrants to the lift will need to size up the situation when the doors slide open and then act decisively. Once in, for most people the rule is simple – look down, or look at your phone.
Why are we so awkward in lifts?
“You don’t have enough space,” Professor Babette Renneberg, a clinical psychologist at the Free University of Berlin, told the BBC. “Usually when we meet other people we have about an arm’s length of distance between us. And that’s not possible in most elevators.”
In such a small, enclosed space it becomes very important to act in a way that cannot be construed (理解)as threatening or strange. “The easiest way to do this is to avoid eye contact,” she said.

Some jobs require employees to work night shifts. Working the night shifts often means better money, but that also comes negative side effects.
The human body is naturally inclined（倾向于）to work during the day and sleep at night.
In addition to exhaustion from working the night shift, sleep disturbances can occur, even when your body has the opportunity to get some shut-eye during the day.
Working night shifts can also cause social and relational problems. Because many social events happen during the evening, people who work the shift miss out on important relationship-building opportunities.
| A．Working night shifts can help us a lot. |
| B．So working the night shift will take an adjustment. |
| C．Doctor and nurses often work night shifts to care for their patients. |

Lazy people will never amount to anything in life. However, laziness can be defeated once a few changes have been made in your mind.
Another way to fight laziness is to change your mind from passive to active.
Some people fight laziness by removing the temptations(诱惑) that surround them. A television in the living room may provide entertainment, but watching too much TV often contributes to laziness. Create a reward system for yourself, just as parents do for a child to promote responsibility.
Finally, taking exercise regularly can help you fight laziness.

【推荐1】In our magazine’s document room, from the June 1920 issue, I discovered a piece, What Editors Do, by Hazel Miller. What she talks about caught my eye: The first World War and its ending just two years before.
“During 1917 and 1918, when the World War was going, there was a huge demand for war material,” Miller writes. “Most magazines were carrying practically nothing but war stories. When the War ended in November, 1918, some editors still had a goodly supply of war fiction and articles—for which they had paid real money—on their hands, which most people by now are fed up with.”
Her words have stuck with me for the past 12 months as we’ve weighed which COVID-19 stories to run and which to hold. I’m writing these words with thick snow outside my window, but they will reach you in the green of spring. Will you be vaccinated(接种疫苗) and tired of reading about COVID-19 then?
We say writing is an art, and publishing is a business, but I worry we forget that publishing is also a gamble(赌博), Except for the immediate publication, everyone in the industry—agents, acquiring editors, magazine and journal editors, etc.—are betting on a story’s success in a future we cannot see. As is the nature of fortune telling, we are not so sure we will not occasionally lose: The 1920 editors sitting on a store of war stories no one wants, for example.
With so many factors outside your control, and so much uncertainty in the industry, isn’t it better to have stories written from the heart that you are truly enthusiastic about rather than some to please an ever-changing publishing market?
My future reader, it’s my hope that this issue finds you this spring doing just that: Writing the stories you need to tell—and the ones that will delight your own future readers for years to come.
1. What does the writer probably do?| A．A journalist. | B．An editor. | C．A librarian. | D．A historian. |
| A．The First World War shouldn’t have ended too soon. |

【推荐2】Blind imitation (模仿) is self-destruction. To those who do not recognize their unique worth, imitation appears attractive; to those who know their strength, imitation is unacceptable.
In the early stages of skill or character development, imitation is helpful. When I first learned to cook, I used recipes (菜谱) and turned out some tasty dishes. But soon I grew bored. Why follow someone else’s way of cooking when I could create my own? Imitating role models is like using training wheels on a child’s bicycle; they help you get going, but once you find your own balance, you fly faster and farther without relying on them.
In daily life, imitation can hurt us if we subconsciously (下意识地) hold poor role models. If, as a child, you observed people whose lives were bad, you may have accepted their fear and pain as normal and gone on to follow what they did. If you do not make strong choices for yourself, you will get the results of the weak choices of others. In the field of entertainment, our culture glorifies celebrities. Those stars look great on screen. But when they step off screen, their personal lives may be disastrous. If you are going to follow someone, focus on their talent, not their bad character or unacceptable behaviors.
Blessed is the person willing to act on their sudden desire to create something unique. Think of the movies, books, teachers, and friends that have affected you most deeply. They touched you because their creations were motivated by inspiration not desperation. The world is changed not by those who do what has been done before them, but by those who do what has been done inside them. Creative people have an endless resource of ideas. The problem a creator faces is not running out of material; it is what to do with the material knocking at the door of imagination.
Study you role models, accept the gifts they have given, and leave behind what does not server you. Then you can say, “I stand on the shoulders of my ancestors’ tragedies and declare victory, and know that they are cheering on.”

【推荐3】It is easy to forget that the public education system is a relatively new phenomenon. In fact, compulsory public education has only been in place for the past two centuries. Before that, most education of children took place within the family and the community.
Today, however, more parents are homeschooling their children due to dissatisfaction with the educational system. Many parents are unhappy about class size, as well as problems inside the classroom. In many schools, one teacher is responsible for 30 or 40 pupils. The result is that children are deprived of the attention they need. Escalating classroom violence has also motivated some parents to remove their children from school. Supporters of homeschooling believe that children learn better when they are in a secure, loving environment. They point out that homeschooled children reportedly do just as well as those who have been in the classroom, and that they can also pick and choose what to study and when to study, thus enabling them to learn at their own pace.
In contrast, critics say that homeschoolers miss out on learning important social skills because they have little interaction with their peers. Besides, they have raised concerns that many parents who homeschool have no teacher training and are not competent educators of all the subjects taught in schools.
With an increasing number of disgruntled parents taking their children out of class, many school officials are looking for ways to restore parents’ confidence in the public education system. Some schools in the United States have opened their doors to homeschoolers on a part-time basis, allowing these children to attend classes once or twice a week, or to take part in extracurricular activities such as playing football or taking ballet lessons. While many parents will not completely put their confidence back into the system, many of them have reached a compromise that allows their children the extra benefits of peer interaction and access to a wider choice of activities.
Whatever the arguments for or against it, homeschooling is growing. There are now websites, support groups, and conventions that help parents learn more about educating their children. Though once the last resort for troubled children, homeschooling today is becoming an alternative to the public educational system.

【推荐1】The new garbage sorting regulation has taken effect in Shanghai starting from July 1. Many citizens are still confused about the classification of the four different types of trash. Thankfully, authorities have released an official guideline to explain the new rules.
The guideline, published by the Shanghai Greenery and Public Sanitation Bureau, provides a rather clear definition on the four kinds of waste: recyclable waste, harmful waste, household food waste and residual (剩余的) waste.
Harmful waste, as the name suggests, includes various poisonous materials like used batteries, light bulbs, out-of-date medicines, paint and pesticides.
Household food waste — which is translated to “wet trash” in Chinese — refers to food leftovers, rotten food, pet food, fruit peels, remains of TCM herbs (中药) and flowers.
Paper, plastic, glass, metal and textiles (纺织品) are counted as recyclable waste.
The definition of residual waste is a little confusing. Anything that is not listed above belongs to this category.
As specific as the new guideline is, residents still have a hard time sorting trash correctly and are finding it challenging to memorize them all. For instance, both plastic bottles and bubble tea or coffee cups are plastic materials. However, the former falls to the category of recyclable waste and the latter belongs to residual waste. To save the hassle, some netizens have come up with their own way to sort trash.
“We should do this from a pig’s angle,” commented one netizen. “Those edible (可食用的) for pigs are household food waste. Those even pigs don’t want to eat are residual waste. If a pig consumes something and dies of it, then something must be harmful waste. Those that can be sold and the money we gain can be used to purchase pigs are recyclable waste.”
The new regulation came into effect on July 1. Those who do not sort their trash properly will be fined RMB 200.

【推荐2】I like being 100% stimulant free—no coffee, caffeinated tea, chocolate, caffeinated soda, etc. I base this on lots of personal experimentation. I’ve gone some years of my life with no stimulants, and I’ve also gone for a long time consuming coffee daily. The two modes of living are totally different.
Caffeine tends to make me obsess more over minor tasks and lose focus on big picture goals. When I consume coffee daily, Ill check email more often. I’ll spend more time on social media. I’ll web surf more. I’ll spend more time organizing and reorganizing instead of moving the needle forward on big projects. I’ll feel extra busy but have less to show for it.
Stimulants always exhaust me eventually, especially after months of daily use. I can’t seem to make good progress on bigger projects, and I can tell that my mind is becoming too chaotic. I might spend 8 hours at my desk and get 90 minutes of important work done. I know I am at the point when I need to take at least several weeks off.
I love the taste of coffee, and its delightful to drink a cup of it, but I’ve learned that I can’t really have any relationship with it if I want to function at my best. It’s way too addictive (上瘾的) for me. If I have even a small amount, I risk slipping into the pattern of having it daily for months.
I’ve learned that its best to avoid chocolate too (including cacao) because chocolate is a gateway drug back to coffee. Same goes for green tea. So while I have enjoyed those in the past, I feel safer not having them. I like how my brain works better when not under the influence of stimulants.

【推荐3】Barry Farmer didn't have the easiest childhood, but it was an experience that made him who he is today—a foster father（养父）.
“When I was very little, I was going from home to home, living with friends of my parents. ” Farmer said. He then lived with his aunt, followed by a foster home.
When Farmer was four years old, something happened that would change his life forever： He moved in with his grandmother. At his grandmother's house, he had neighborhood friends, a good school and a sense of community. That stability was beneficial to Farmer,
“I lost my parents but I gained a whole village of support. That inspired me to become a foster parent, too," Farmer said.
When he was just 20 years old, he saw an advertisement about how to become a foster parent, "A year after getting licensed, I got my first case," he said. Farmer said social workers were not willing to assign（分配）him cases since he was not old enough, but he finally got his first child.
About a month after that child moved out, Farmer received another case. Farmer decided to take in 8-year-old Jaxon, “He was supposed to be with me temporarily," Farmer said. However, when Jaxon moved out, he was placed with a family who was supposed to adopt him but he didn't like it, "He missed me and I missed him because I wasn't really prepared for him to go,” Farmer said, "That's when I made a decision to keep him. ”
Foster care itself is so unpredictable. You don't know what to expect once you sign up," Farmer said, “There's no easy way to foster. It's an emotional（情感上的）journey. And you have to put your own personal feelings aside to make sure you're doing what's best for the children. But at last, both you and your foster children can benefit a lot. ”

【推荐1】Long the symbolic face of endangered species in China, the giant panda has made significant progress in recent years. In the 1980s, only about 1,216 pandas were left in the wild, but the most recent calculation counted more than 1,800.
The increased numbers could be due to improved survey methods or true growth from better protection measures. In either case, pandas still face plenty of threats, of which habitat loss is the main one to survival. Human growth in their areas, combined with climate change has led to the loss of livable land. In addition, pandas have been facing dangers from illegal hunting.
Because pandas are now distributed across China in groups, with each group separated from the others due to habitat destruction, the Chinese government is creating a huge national park in southwestern China to protect them. Giant Panda National Park will cover 10,476 square miles (27,132 square kilometers), which is nearly three times the area of Yellowstone National Park. The new park will make an effort to reunite populations that have become separated from one another.
This project “takes the long view,” Bob Tansey, China policy adviser for The Nature Conservancy, tells National Geographic. “Generally, pandas are doing well. But what will they need in the future? Connectivity.”
The park’s connectivity should give isolated(独居的)pandas a better chance to breed. Giant pandas have a very low reproductive rate, with females generally usually giving birth every two years, the WWF reports. The new park eventually should give them room to find mates, thus resulting in more young pandas. After all, habitat will remain patchy until degraded lands are restored and stronger land-use restrictions come into effect that make wildlife corridors(廊道) possible.
The park also aims to promote the local economy, the Associated Press reports. An official involved in the park’s planning tells the state-run China Daily this project would help ease poverty among the 170,000 people living within the park’s proposed territory. The government is offering financial support to encourage people living in the area to relocate, according to National Geographic. Some areas of the park also eventually will allow tourism.

【推荐2】Close to the North Pole, remote and rocky Plateau Mountain in the Norwegian archipelago of Svalbard seems an unlikely（不可能的）spot for any global effort to safeguard agriculture. In this cold and deserted environment, no grains, no gardens, no trees can grow. But at the end of a 130-meter-long tunnel cut out of solid stone is a room filled with humanity’s most precious treasure, the largest and most diverse seed collection------ more than a half-billion seeds.
A quiet rescue mission（任务）is under way. With growing evidence that unchecked climate change will seriously affect food production and threaten the diversity（多样性）of crops around the world, the Svalbard Global Seed Vault represents a major step towards ensuring the preservation（保存） of hundreds of thousands of crop varieties. This is a seed collection, but more importantly, it is a collection of the traits（特点）found within the seeds: the genes that give one variety resistance（抵抗力）to a particular pest and another variety tolerance（忍耐力）for hot, dry weather.
Few people will ever see or come into contact with the contents of this vault. In sealed（密封的）boxes, behind many locked doors, monitored by electronic security systems, enveloped in below-zero temperatures, and surrounded by tons of rock, hundreds of millions of seeds are protected in their mountain fortress（设防的地方）. Frozen in such conditions inside the mountain, seeds of most major crops will remain viable for hundreds of years, or longer. Seeds of some are capable of keeping their ability to grow for thousands of years.
Everyone can look back now and say that the Seed Vault was a good and obvious idea, and that of course the Norwegian government should have approved（批准通过）and funded it. But back in 2004, when the Seed Vault was first proposed, it was viewed as a crazy, impractical, and expensive idea.
We knew that nothing would provide a definite guarantee（保证）. But we were tired, fed up, and frankly scared of the steady, greater losses of crop diversity. The Seed Vault was built by optimists who wanted to do something to preserve options so that humanity and its crops might be better prepared for change.
The Seed Vault is about hope and commitment（承诺）—about what can be done if countries come together and work cooperatively to accomplish something significant, long-lasting, and worthy of who we are and wish to be.

【推荐3】Coca-Cola, which reportedly produced more than 3 million tons of plastic packaging in 2017, announced Thursday it wants to “help fix the world’s plastic waste problem one community (社区) at a time.”
The soda giant is doing so by providing $ 5.4 million for recycling programs in cities like Atlanta, Boston, Denver and Houston. In these cities, partners, like The Green Blue Institute and The Recycling Partnership, which receive the money, will work together to improve recycling rates.
“We focus on areas where we have the ability to make the biggest influence on communities through the funding and expert skills of Coca-Cola employees,” Carlos Pagoagoa, Coca-Cola’s group director of community partnerships, said in a statement. “In each city, local partners will work together to identify barriers to recycling on a local level and test a range of solutions,” he added. “We hope the learnings from these ‘model markets’ can offer solutions to other cities facing similar challenges.”
As part of the effort, The Recycling Partnership and the city of Atlanta, where the cola company’s headquarters are based, will send street teams out to open recycling carts and leave citizens cards informing them what they can and can’t recycle, and let them know how their efforts work.
“Two of the most urgent problems with recycling in the U. S. today are lack of access, followed by pollution in recycling,” Keefe Harrison, CEO of The Recycling Partnership, said in a statement. “We know from the success of Atlanta in 2017 that the citizens want to recycle, and that communicating with them in the street works.”
Last year, Coca-Cola announced its task to collect and reuse a bottle or can for each one it sells, and increase the amount of its products out of recycled materials to 50% by 2030. The brand also aims to make all its packaging fully recyclable by 2025.
