Given that many people 's moods(情绪)are regulated by the chemical action of chocolate, it was probably only a matter of time before somebody made the chocolate shop similar to a drugstore of Chinese medicine. Looking like a setting from the film Charlie& the Chocolate Factory, Singapore's Chocolate Research Facility (CRF) has over 100 varieties of chocolates. Its founder is Chris Lee who grew up at his parents' comer store with one hand almost always in the jar of sweets.

    If the CRF seems to be a smart idea, that's because Lee is not merely a seasoned salesperson but also head of a marketing department that has business relations with big names such as Levi's and Sony. That idea surely results in the imagination at work when it comes to making different flavored (味道)chocolates.

    The CRF's produce is “green” made within the country and divided into10 lines, with the Alcohol Series being the most popular. The Exotic Series—with Sichuan pepper, red bean (豆), cheese and other flavors also—does well and is fun to taste. And for chocolate snobs, who think that they have a better knowledge of chocolate than others, the Connoisseur Series uses cocoa beans from Togo, Cuba, Venezuela , and Ghana, among others.

    On January 13, 2016, France became the first country in the world to pass a law requiring supermarkets to donate food that is approaching its expiration date (保质期) instead of throwing it away. The regulation that applies to supermarkets over 4,000 square feet requires stores to sign official donation agreements with local food banks.

    The law also makes it illegal for stores to pour water over nearly-expired food, or store it inside locked warehouses until it is picked up by the garbage trucks. These measures are often undertaken by supermarkets to prevent the hungry from searching for food through the dustbins.

    Though that may appear cruel, the stores claim they do it to avoid potential food poisoning that could occur if the product is on its way past its expiry. Those who do not obey the new law face the risk of heavy fines.

    Also, excess goods like yogurt or milk that are likely to go bad quickly are now allowed to be donated directly to the food banks. Though this has always been possible, the current process is long and complex, making it difficult for producers to give away the food in a timely manner.

    France's food banks are of course thrilled about the possibility of receiving extra food. Jacques Bailet, who heads a network of French food banks called the Banques Alimentaires, says that of the 110,000 tons of goods received annually, only 36,000 tons comes from supermarkets. Bailet estimates (估计) that just a 15% increase in supermarket donations would translate to over 10 million additional meals to feed the hungry each year.

    Though this is a great first step, Arash Dermabarsh, the activist responsible for the grassroots movement that led to the ban, is not done. He now wants to extend the law to other places like restaurants and also try to convince other countries in the European Union to pass similar regulations. These steps are necessary because of the over 9 million tons of food wasted in France; an astonishing 67% is thrown away by consumers, with supermarkets and restaurants making up the rest.

    Andy rode slowly on his way to school, day-dreaming about the fishing trip that his father had promised him. He was so busy dreaming about all the fish he would catch that he was unaware of everything else around him.

    He rode along until a strange sound drew him to the present. He came to a stop and looked up to the sky. What he saw frightened him. A huge group of bees filled the sky like dark cloud and seemed to be heading angrily towards him.

    With no time to waste Andy sped off in the opposite direction, riding quickly without knowing how to escape the group. With a rapidly beating heart and his legs pumping quickly, he sped down the rough road. As the bees came closer, his fear increased. Andy knew that he was sensitive(敏感的) to bee stings (蜇). Last time a sting had put him in hospital—and that was only one bee sting! He had been forced to stay in bed for two whole days. Suddenly, his father's words came to him. "When you are in a dangerous situation, don't panic. Stay calm, use your brain and think your ways out of it."

    On a nearby hill, he could see smoke waving slowly from the chimney(烟囱) of the Nelson family home. "Bees don't like smoke," he thought. "They couldn't get into the house." Andy raced towards the Nelson house, but the bees were gaining around. Andy knew he could not reach the house in time. He guessed that the bees would catch up with him soon.

    Suddenly, out of the corner of his eyes, he saw a small pond used by Mr. Nelson to water his vegetable garden. Off his bike and into the cool water he jumped, disappearing below the surface and away from the bees. After holding his breath for as long as he could, Andy came up for air and noticed the bees have gone. Pulling himself out of the water, he walked up the hill and rang the doorbell. Mr. Nelson took him inside and rang his mother.

    "You'll really need that fishing break to help you recover(恢复)," laughed his mother. "Thank goodness you didn't panic!" But Andy did not hear her. He was dreaming once again of the fish he would catch tomorrow.

    A bicycle may be seen by most people as just another vehicle (交通工具), but for many Londoners, cycling is a way of life. According to an official UK government survey in 2017, about 570,000 bike journeys are made every day in London. In fact, almost half of the vehicles that pass over London Bridge each day are bikes.

    London introduced a public bike-sharing system in 2010. "There can be no doubt that our trusty bicycles have changed the way people get around our great city," Johnson told the Guardian in 2015.

    In London, bikes are used for more than just taking short trips to and from the subway. No matter where you want to go in the city, taking a bike is usually the quickest and easiest choice.

    And it's not just shared bikes that the government is encouraging people to ride. In many companies across the UK, the UK government's Cycle to Work scheme (骑行倡议) allows employees to buy a brand new bike without having to pay any tax (税). This means that it's common to see many people cycling to and from work, and some employers even provide workplace showers and lockers (储物柜) for their workers. More importantly, a cycle-friendly boss may let you off for being late if you rode a bike to work.

    Not only is it great for the environment and our body, cycling is also good for the mind. According to National Geographic Magazine, "Bike riding can improve people's happiness."

    About 5,000 children die each day due to preventable diseases such as cholera and dysentery (痢疾) , which spread when people use unclean water for drinking or cooking. A lack of water for personal health leads to the spread of totally preventable diseases like trachoma, which has blinded some six million people.

    Water troubles also trap many low-income families in a cycle of poverty and poor education and the poorest suffer most from lack of access to water. People who spend much of their time on ill health, caring for sick children, or collecting water at distances averaging 3.75 miles a day don't have educational and economic opportunities to better their lives.

    Agriculture is called the lion's share of freshwater worldwide, using some 70 percent, and industrial uses consume another 22 percent. Water areas have no political borders and nations don't always work together to share common resources, so water can be a frequent source of international conflict as well.

    Day-by-day demand keeps growing, further needing water sources, from great rivers to groundwater. “We're going deeper into debt on our groundwater use,” Postel said, “and that has very significant impacts on global water security. The rate of groundwater consumption has doubled since 1960.”

    Some of Earth's groundwater is fossil water created when Earth's climate was far different. Today such water is as limited as petrol. “But we're pumping much of them out faster than ever,” Postel explained. “Humanity's growing thirst also causes a major problem about water and our ecosystems. And that also creates a cost to us, to our sons and to our grandsons, not just to nature.”

    There is a common belief among parents that schools are no longer interested in spelling. No school I have taught in has ever considered spelling unimportant as a basic skill. There are, however, quite different ideas about how to teach it, or how much priority(优先) it must be given over general language development and writing ability. The problem is, how to encourage a child to express himself freely in writing without holding him back with spelling.

    If spelling becomes the only point of his teacher's interest, clearly a bright child will be likely to "play safe". He will write only words within his spelling range(范围). That's why teachers often encourage the early use of dictionaries and pay attention to content rather than technical ability.

    I was once shocked to read on the bottom of a sensitive piece of writing about a personal experience: "This work is terrible! There are far too many spelling mistakes." It may have been a sharp criticism(批评) of the pupils technical abilities in writing, but it was also a sad thing for the teacher who had omitted to read the composition, which contained some beautiful expressions of the child's deep feelings. The teacher was not wrong to draw attention to the mistakes, but if his priority had centered on the child's ideas, an expression of his disappointment with the presentation would have given the pupil more hope to seek improvement.
