【推荐1】Maple syrup (枫糖浆) is a sweetener from maple tree sap (树汁). Many people use it in baking in place of sugar or other sweeteners, some use it in tea instead of honey and it is frequently used as a topping for pancakes, waffles, and other breakfast foods. Since true maple syrup is rather expensive, a wide range of false maple syrup exist.

This sweetener originated in the northeast region of North America, and it is in this region that most of the world’s maple syrup is still produced. Vermont, New Hampshire Maine, and the eastern portion of Canada are all known for their fine syrup, each with slightly different flavor qualities.

This sweetener is produced by tapping maple trees to release and collect their sap. A tree's sap is the liquid that, much like blood in animals, carries water and food to different parts of the tree to keep it nourished. A mature maple produces about ten gallons of sap in a given season, after which the tree will wall off the channel that has been tapped, so that a new tap has to be drilled the next season. Maples are not tapped for syrup until they are at least 40 years old and have reached a certain size, to ensure that no harm comes to the tree through the tapping process .

An immense amount of sap is required to produce maple syrup because the watery sap must be reduced to achieve the proper thickness and taste. Although the exact amount depends on the sweetness of the sap, in general it takes about 40 times as much maple sap to produce a portion of syrup. This may be further reduced to create thicker delicacies, such as maple butter, maple cream , and maple sugar.

In the Us, there are grade A and Grade B syrups, with three sub-divisions of Grade A: light amber, medium amber, and dark amber. Grade B is even darker than Grade A dark amber. Many people assume that the grading system is also indicative of quality, but in reality, it only helps to differentiate the color and taste of the syrup, which is a matter of personal preference. The tastes are different, but to say one is objectively “better” than another would be incorrect.

【推荐2】Tea is currently the world’s most popular drink, only after water. However, there was a time when tea was known only to the Chinese.     1     And how did it get to conquer the world to the extent that people often describe something they really like as their “Cup of tea?”

While we know that tea drink started in China, its true origin remains something of a mystery. Legend has it that about 5,000 years ago, Shennong came across tea when dried leaves blew into a pot of boiling water. Following his discovery, tea was used as medicine, included in meals and later offered as a refreshing drink to officials and noblemen.     2    

    3     Over the years, as tea drinking became an important part of China’s rich culture. The great Tang poet Du Fu described his tea-drinking experience in poetic language. Lu Yu, a tea master, wrote The Classic of Tea, which remains the earliest and most famous detailed study on tea in the world.

It is then not surprising that the beauty of tea was eventually spread to a wider world.     4     Porters (脚夫) carrying back-breaking loads of tea bricks made their way through dangerous snow-covered mountain passes, to trade Sichuan and Yunnan tea for horses:     5     As early as the Tang Dynasty, Japanese monks came to study in China and took with them tea seeds and tea-making customs when returning to Japan. Around the 1600s, tea was shipped to Europe from China by Portuguese and Dutch sea traders.

【推荐1】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 vehicle. The extra dirt leads us to do one of the 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 used and the types of chemicals used to get rid of 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 in a container 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 piece of 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 Schombert, executive director of 3 Rivers Wet Weather. Even when car owners use natural soaps to wash the 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 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.

【推荐3】“It's a big hammer to crack a nut.” This is how one angry parent described   the recent crackdown (严厉的打击) by London police on parents who drop their kids off at school by car. Yes, you read that correctly—the very mode of transportation that many American schools insist is the only safe way to deliver kids to school is now considered illegal in the UK.

The decision to fine any vehicles seen dropping off or picking up kids within a particular zone of east London comes from city councilors' (议员) long­term efforts to make the area safer and less crowded. They say they've been trying for years “to encourage reasonable parking”， but in vain. Neighborhood residents complain frequently about their driveways being blocked by illegally parked cars for 15 minutes or more, often while they're trying to get to work, and the streets are long overcrowded.

Now the rules have changed. Some parents are angry.Angie is a mother who made the “big hammer” comment and says the crackdown is “way over the top”. The nearest drop­off point for her six­year­old is now a five­minute walk from the school. Others are happy with the decision, severe though it may seem.

Councilor Jason Frost said：“Traffic has been clearly reduced, and more children are now walking to school, which is a great outcome. I would rather have complaints that we are slightly inconveniencing parents than hear that a child had been seriously injured because nothing was done.”

I witness daily the chaos(混乱) created by these in­town drivers, when I walk my own kids to school. There's a parking lot crowded with vehicles and a slow­moving train of cars moving in circles, many filling the air with harmful smoke. Meanwhile，the conversations around overweight children and the importance of daily physical activities continue to stand out in schools.

【推荐1】An Edinburgh inventor has created a fully biodegradable bottle that is made from paper and a secret combination of plant materials, and it could help save the planet's oceans from plastic pollution and can also be eaten by sea creatures.

The Edinburgh-based Durham University chemistry graduate James Longcroft started a non-profit bottled water company two years ago. He wanted to put all his profits into a charity that provided clean drinking water to countries in Africa.

However, after concerns about the environmental impact of plastic bottles, Mr. Longcroft decided the Edinburgh and London-based company, Choose Water, should go plastic-free. So he came up with a new type of water bottle—a waterproof paper bottle.

“The outside is made from recycled paper, but the inside has to be waterproof, and provides strength so the bottle would keep its structure, and keep the water fresh,” Mr. Longcroft said.

When the bottle is thrown in the ocean the degrading process begins within hours leaving the bottle totally degraded (分解)within weeks. The steel cap breaks down within a year.

Mr. Longcroft now believes these novel bottles could revolutionise the industry and says the cost of producing the bottle is around 5 pence more than one made from single-use plastic.

“The main difficulty we face is breaking into a saturated (饱和的)market and competing with an old industry,” he said. “Changing an industry will be a big uphill battle, but with the support from the public, we will change the way we look at bottled water.”

Researchers warn that eight million tonnes of plastics currently find their way into the ocean every year which will stay in the environment for centuries.

“We really want to get our bottles on shelves and into people's hands as soon as possible—if we can stop even one plastic bottle ending up in the environment it will be worth it,” said Mr Longcroft.

【推荐2】Cultural Center Adds Classes for Young Adults

The Allendale Cultural Center has expanded its arts program to include classes for young adults. Director Leah Martin announced Monday that beginning in September, three new classes will be offered to the Allendale community. The course titles will be Yoga for Teenagers; Hip Hop Dance: Learning the Latest Moves; and Creative Journaling for Teens: Discovering the Writer Within. The latter course will not be held at the Allendale Cultural Center but instead will meet at the Allendale Public Library.

Staff member Tricia Cousins will teach the yoga and hip hop classes. Ms. Cousins is an accomplished choreographer (舞蹈教师) as well as an experienced dance educator. She has an MA in dance education from Teachers College, Columbia University, where she wrote a thesis on the pedagogical (教学法的) effectiveness of dance education. The journaling class will be taught by Betsy Milford. Ms. Milford is the head librarian at the Allendale Public Library as well as a columnist for the professional journal Library Focus.

The courses are part of the Allendale Cultural Center’s Project Teen, which was initiated by Leah Martin, Director of the Cultural Center. According to Martin, this project is a direct result of her efforts to make the center a more essential part of the Allendale community. Over the last several years, the number of people who have visited the cultural center for classes or events has steadily declined. Project Teen is primarily funded by a generous grant from The McGee Arts Foundation, an organization devoted to bringing arts programs to young adults. Martin oversees the Project Teen board, which consists of five board members. Two board members are students at Allendale’s Brookdale High School; the other three are adults with backgrounds in education and the arts.

The creative journaling class will be cosponsored by Brookdale High School, and students who complete the class will be given the opportunity to publish one of their journal entries in Pulse, Brookdale’s student literary magazine. Students who complete the hip hop class will be eligible to participate in the Allendale Review, an annual concert sponsored by the cultural center that features local actors, musicians, and dancers. All classes are scheduled to begin immediately following school dismissal, and transportation will be available from Brookdale High School to the Allendale Cultural Center and the Allendale Public Library. For more information about Project Teen, contact the cultural center’s programming office at 988-0099 or drop by the office after June 1 to pick up a fall course catalog. The office is located on the third floor of the Allendale Town Hall.

【推荐3】Most young people enjoy some form of physical activity. It may be walking, cycling or swimming, or in winter, skating or skiing. It may be a game of some kind of football, hockey, golf, or tennis. It may be mountaineering.

Those who have an interest in climbing high and difficult mountains are often looked upon with astonishment. Why are men and women willing to suffer cold and hardship, and to take risk on high mountains? This astonishment is caused probably by the difference between mountaineering and other forms of activity to which men give their leisure.

Mountaineering is a sport and not a game. There are no man-made rules, as there are for such games as golf and football. There are, of course, rules of a different thing that it would be dangerous to ignore, but it is this freedom from man-made rules that makes mountaineering attractive to many people. Those who climb mountains are free to use their own methods.

If we compare mountaineering and some other sports, we might think that one big difference is that mountaineering is not a “team game”. We should be mistaken in this. There are, it is true, no “matches” between “teams” of climbers, but when climbers are on a rock face linked by a rope on which their lives may depend, there is obviously teamwork.

The mountain climber knows that he may have to fight forces that are stronger and more powerful than men. He has to fight the forces of nature. His sport requires high mental and physical qualities.

A mountain climber continues to improve in skill year after year. A skier is probably past his best by the age of thirty, and most international tennis champions are in their early twenties. But it is not unusual for a man of fifty or sixty to climb the highest mountains in the Alps. They may take more time than younger men, but they probably climb with more skill and less waste of efforts, and they certainly experience equal enjoyment.
