The stories we share with one another are important. They show wisdom and provide inspiration. They are important to our development. But sometimes people choose not to tell.

    Considering the negative effects of not sharing a story in the news, people are wondering if public health officials are holding back too much information about the recent outbreak of Ebola.

    There is a danger in holding back stories that ought to be told. Bobette Buster said it like this, “The fact is, history has shown us that stories not told can become like a dangerous genie (妖怪) left in a bottle. When they are finally uncorked(透漏), their power to destroy is set free."

    There are a number of reasons why we hide parts of our story: they often show our weaknesses or expose our disadvantages; they require courage and strength to share; and of course, there are some stories that should be kept secret—especially those that embarrass someone else.

    Most of us have two selves: the one we display on the outside and the one we actually are on the inside. And the better we get at hiding the stories that show our true selves, the more damage we may be causing to ourselves and to others.

    Honesty and openness is important: It proves we are trustworthy. It displays we are human. We are not perfect or better. It highlights the importance of hard work and personal development. Hard work may not allow us to overcome our disadvantages completely. But with hard work, we do not have to be restricted to our mistakes.

    Does this mean we admit every weakness, every disadvantage, and every secret regret to everybody we meet? No, of course not. There is a time and a place and a certain level of relationship necessary for some stories to be told in an appropriate manner.

    One of the most important things in the world is friendship. In order to have friends, you have to be a friend. But how can you be a good friend at school?

    Listen — Listen when they are talking. Don't say anything unless they ask you a question. Sometimes it's not necessary for you to have anything to say; they just need someone to talk to about their feelings.

    Help them — If your friend is ever in need of something, be there to help them. You should try to put them first, but make sure you don't do everything they want you to do. Try to take an extra (额外的) pencil or pen with you to classes in case (以防) they forget one. Have a little extra money in your pocket in case they forget something they need.

    Be there for them — Try to make something for your friend to help make them feel better in hard times. Making cards and encouraging them are among the nicest things you can do for a friend. Marilyn Monroe, a famous U.S. actor, once said, “I often make mistakes. Sometimes I am out of control. But if you can't stay with me at my worst, you are sure not to deserve (值得) to be with me at my best.” Always remember this! If you don't want to stay with your friends when they're in hard times, then you don't deserve to be with them when they're having a good time!

    ______ — Try to make plans with your friends. Go shopping, go for ice cream, have a party, go to a movie and so on. Take time to know each other even better by doing something you both enjoy. By planning things together, you both can have a good time. And you'll remember these things when you're all old!

    Suppose you become a leader in an organization. It's very likely that you'll want to have volunteers to help with the organization's activities. To do so, it should help to understand why people undertake volunteer work and what keeps their interest in the work.

    Let's begin with the question of why people volunteer. Researchers have identified several factors that motivate people to get involved. For example, people volunteer to express personal values related to unselfishness, to expand their range of experiences, and to strengthen social relationships. If volunteer positions do not meet these needs, people may not wish to participate. To select volunteers, you may need to understand the motivations of the people you wish to attract.

    People also volunteer because they are required to do so. To increase levels of community service, some schools have launched compulsory volunteer programs. Unfortunately, these programs can shift people's wish of participation from an internal factor (e.g. "I volunteer because it's important to me") to an external factor (e.g. "I volunteer because I'm required to do so"). When that happens, people become less likely to volunteer in the future. People must be sensitive to this possibility when they make volunteer activities a must.

    Once people begin to volunteer, what leads them to remain in their positions over time? To answer this question, researchers have conducted follow-up studies in which they track volunteers over time. For instance, one study followed 238 volunteers in Florida over a year. One of the most important factors that influenced their satisfaction as volunteers was the amount of suffering they experienced in their volunteer positions. Although this result may not surprise you, it leads to important practical advice. The researchers note that attention should be given to "training methods that would prepare volunteers for troublesome situations or provide them with strategies for coping with the problem they do experience".

    Another study of 302 volunteers at hospitals in Chicago focused on individual differences in the degree to which people view "volunteer" as an important social role. It was assumed that those people for whom the role of volunteer was most part of their personal identity would also be most likely to continue volunteer work. Participants indicated the degree to which the social role mattered by responding to statements such as "Volunteering in Hospital is an important part of who I am." Consistent with the researchers' expectations, they found a positive correlation (正相关) between the strength of role identity and the length of time people continued to volunteer. These results, once again, lead to concrete advice: "Once an individual begins volunteering, continued efforts might focus on developing a volunteer role identity…Items like T-shirts that allow volunteers to be recognized publicly for their contributions can help strengthen role identity".

    You'll need to take a deep breath before hearing this news. An astonishing 93% of kids around the world live in environments with air pollution levels that are damaging their health, according to a new report by WHO.

    Air pollution is to blame for the deaths of 543, 000 kids under 5 in 2016, with more than one in four deaths of children under five years old being related to environmental issues. Exposure (暴露) to air pollution can damage the health of kids in a variety of ways, either causing or being associated with everything from low birth weight to childhood obesity and so on.

    "The large toll of disease and death revealed (揭示) by these new data should result in an urgent call to action for the global community especially for those in the health department WHO stated. "Strong action to reduce exposure to air pollution offers an opportunity to protect the health of children." The report stressed that health experts should communicate with families, communities and policy-makers about the serious risks of air pollution exposure. "Although more researches into how air pollution affects children's health will continue to be valuable, there is already evidence to justify strong, swift action to prevent the damage it clearly produces," WHO added.

    Disease caused by dirty air is more common in low-and-middle in some countries, especially those in Africa, South-East Asia, and Western Pacific regions. Poor countries in these areas have the highest levels of exposure to household air pollution due to the use of polluting fuels and technologies for basic needs like cooking, heating and lighting.

    Advised solutions include cleaner transport, cleaner cooking and heating fuels and technologies energy-efficient housing and urban planning, safer industrial technologies and better waste management.

    It has been a year since I found out my friend had passed away. I still store his phone number, even though I know calling the number will never reach him again. I feel like if I deleted (删除) his phone number, it would mean he was really gone.

    Over the past few years, we have planned to travel together just to see the dolphins in the sea. However, for some reasons it didn't happen, yet I always took his calls over the years. We shared a lot of interests.

    When I knew that he had been diagnosed (诊断) with a very serious illness and was in hospital, I remembered sending messages to him. I did not receive a message back, so I left a voicemail. A week later, I sent him a message once again. However, I still didn't get a reply. I thought he was busy. During the next several months I was very busy, too. Suddenly, in that mid-summer, I received a short message: "Sorry, Marlynn, He has passed away."

    I was very sad and surprised at the words. I was very sad and regretful. I regretted that I let the months pass without trying again. I worked with many people who had also lost their best friends. The sadness is often unspeakable. There is guilt (内疚), helplessness and sadness that is difficult to put into words.

    Now I try to be grateful for the times and memories we have. I realize the best thing that we can do is value the ones we love.
