You are the collector in the gallery of your life. You collect. You might not mean to but you do. One out of three people collects tangible（有形的）things such as cats, photos and noisy toys.

    There are among some 40 collections that are being shown at “The Museum Of”—the first of several new museums which, over the next two years, will exhibit the objects accumulated by unknown collectors. In doing so, they will promote a popular culture of museums, not what museums normally represent.

    Some of the collections are fairly common—records, model houses. Others are strangely beautiful—branches that have fallen from tree, for example. But they all reveal （显露）a lot of things: ask someone what they collect and their answers will tell you who they are.

    Other on the way include “The museum of Collectors” and “The Museum of Me.”These new ones, it is hoped, will build on the success of “The Museum Of.” The thinkers behind the project want to explore why people collect, and what it means to do so. They hope that visitors who may not have considered themselves collectors will begin to see they, too, collect.

Some collectors say they started or stopped making collections at important point: the beginning or end of adolescence—“it's a growing-up thing; you stop when you grow up,”says one. Other painful times are mentioned, such as the end of a relationship. For time and life can seem so uncontrollable that a steady serial（顺序排列的）arrangement is comforting.

    Now many young people are traveling around the world on their own, not because they have no one to travel with, but because they prefer to go alone．

     Kristina Wegscheider from California first traveled alone when she was at college and believes that it is something everyone should do at least once in their life. “It opens up your mind to new things and pushes you out of your comfort zone.” Wegscheider has visited 46 countries covering all seven continents(洲)．

    In foreign countries, with no one to help you read a map, look after you if you get ill, or lend you money if your wallet is stolen. It is challenging. This is what drives young people to travel alone．It is seen as character building and a chance to prove that they can make it on their own．

    Chris Richardson decided to leave his sales job in Australia to go traveling last year．He set up a website, The Aussie Nomad, to document（记录） his adventures. He said he wished he had traveled alone earlier. “The people you meet, the places you visit, or the things you do, everything is up to you and it forces you to grow as a person,” said the 30-year-old．

    Richardson describes traveling alone like “a shot in the arm”, which “makes you a more confident person that was ready to deal with anything”. He said: “The feeling of having conquered something on my own is a major part of what drives me each day when I'm dealing with a difficult task. I walk around with my head up because I know deep down inside that nothing is impossible if you try.”

    The great 19th century explorer John Muir once said: “Only by going alone in silence can one truly get into the heart of the wilderness.

    China will build a comprehensive (综合性的) network to detect (检测) pollution of the land, sea and air by 2020, employing satellites, drones(无人机)and remote sensors to monitor the environment.

    The national leadership agreed to the network plan in July, saying the government will lead the monitoring, share information among departments and regions, and be held accountable (追究责任) if violations (违规行为) are found, the Ministry of Environmental Protection said on Tuesday.

    Satellites, a major tool for monitoring air pollution, will receive a boost (大力发展)  this year. The ministry said it will accelerate research on two atmospheric environmental monitoring satellites.

    The ministry will improve a remote sensor network, guided by the goals of the 13th Five-Year Plan (2016-2020), which is scheduled to be released at the end of this year, according to the ministry's Environmental Supervision Department.

    Remote monitoring has played a bigger role in locating pollution sources. Drones helped authorities locate polluted areas in the Tengger Desert in northern China and identify scattered summer straw burnings.

    Hebei province, which has a serious air pollution problem, has cooperated with the ministry's Satellite Environment Center to conduct monitoring from satellites and monitoring stations since January last year.

    "We used the data from the center's satellites to forecast the movement of smog during the Asia-Pacific Economic Cooperation meetings in November, "Zhang Feng, an engineer in the Environmental Supervision Department of the provincial environmental watchdog, said on Tuesday.

    Data collected from monitoring stations helped authorities provide accurate forecasts on hazy days during that period, he said.

    Do you find it difficult to put down your mobile phone?

    If yes, you're not alone. These days, many people suffer from the stress of FOMO (fear of missing out). They reach for their mobile phones when they wake up in the morning, and for the rest of the day, they constantly scroll down (向下滚动) the timelines of their social media apps to get the latest updates.

    Despite the convenience smartphones bring, many people struggle with their digital habits.

    As Sameer Samat, US tech Company Google's vice president of product management, said in his speech at the 2018 Google I/O developer conference on May 8, 70 percent of people don't want to spend so much time on their phones.

    This is why during the conference Google introduced an app called Dashboard for the new version (版本) of its Android operating system. This new app includes well-being functions that aim to help users manage the time they spend on their digital devices.

    It all starts with a bird's-eye view. Dashboard allows users to look at all the details of their phone habits. For example, a user can see how many times they've unlocked their phone and how many times they've checked their social media apps, as well as how much time they spend on each app every day.

    Once the users see this information, they'll be able to make some changes. With the App Timer function, users can set a time limit for how long they can use each app for every day. After they've hit the limit, they won't be able to launch the app until the next day.

    But even if users become more mindful of their usage, they're still likely to be drawn in by notifications (通知). This is where the Shush feature comes in. It automatically (自动地) silences incoming calls and notifications when a user puts their phone face down.

    If people truly want to make full use of their free time instead of losing hours using their smart phones, these new functions are just one way of doing that.

After all, who needs to use an app to stop you from using other apps when the easiest answer would be just to use your willpower?

    It's not easy being a teenager– nor is it easy being the parent of a teenager. You can make your child feel angry, hurt, or misunderstood by what you say without realizing it yourself. It is important to give your child the space he needs to grow while gently letting him know that you'll still be there for him when he needs you.

    Expect a lot from your child, just not everything. Except for health and safety problems, such as drug use or careless driving, consider everything else open to discussion to help them grow up more independently. If your child is unwilling to discuss something, don't insist he tell you what's on his mind. The more you insist, the more likely that he'll clam up. Instead, let him attempt to solve things by himself. At the same time, remind him that you're always there for him should he seek advice or help. Show respect for your teenager's privacy (隐私). Never read his mail or listen in on personal conversations.

    Teach your teenager that the family phone is for the whole family, which can make them more mature. If your child talks on the family's telephone for too long, tell him he can talk for 15 minutes, but then he must stay off the phone for at least an equal period of time. This not only frees up the line so that other family members can make and receive calls, but teaches your teenager moderation (节制). Or if you are open to the idea, allow your teenager his own phone that he pays for with his own pocket money or a part-time job.

    Supermarket shoppers who buy lots of foods on "two for one" deals are far more likely to be obese (肥胖的), a major study suggests.

    Cancer Research UK found that those with highest consumption of discounted foods were at 50 percent greater risk of obesity, compared with those with low take-up of such deals.

    The study of more than 16,000 households found almost one in three food and drink items in UK supermarket baskets were bought on promotion. And the discounts were far more likely to be applied to unhealthy foods, with almost half of all chocolate, crisps, popcorn, and savoury snacks bought on promotion.

    Shoppers whose baskets contained between 40 and 80 percent of goods on special offer were 54 percent more likely to be obese than those with a maximum 20 percent of foods on such deals. Those with highest take-up of the deals bought 30 percent less fruit, and nearly 25 percent fewer vegetables than those shunning the deals.

    The study follows a government consultation on proposals to ban "buy one, get one free" deals on unhealthy foods and supermarket "guilt lanes" as part of its childhood obesity strategy.

    One in five children are overweight or obese when they start primary school, rising to around one in three when they leave.

    Research has found that obesity increases the risk of 13 different types of cancer including bowel and breast disease.

    Alison Cox, director of cancer prevention at Cancer Research UK, said: "The government's proposed 9 p. m. ban on junk food ads is a step forward in fighting childhood obesity. Now we want to see restrictions on price promotions for unhealthy food and drink items, as well as those strategically placed at checkouts. This will help families to make healthier choices.

    "There isn't one magic fix for the problem, but getting rid of these encouragements to buy unhealthy food is key to changing it."
