A new study of 8,000 young people in the Journal of Health and Social Behavior shows that although love can make adults live healthily and happily, it is a bad thing for young people．Puppy love（早恋）may bring stress for young people and can lead to depression (沮丧，抑郁）. The study shows that girls become more depressed than boys, and younger girls are the worst of all．

    The possible reason for the connection between love and higher risk of depression for girls is “loss of self”．According to the study，even though boys would say “lose themselves in a romantic relationship”，this “loss of self” is much more likely to lead to depression when it happens to girls. Young girls who have romantic relationships usually like hiding their feelings and opinions．They won't tell that to their parents．

    Dr Marianm Kaufman，an expert on young people problems，says 15% to 20% young people will have depression during their growing. Trying romance often causes the depression．She advises kids not to jump into romance too early. During growing up，it is important for young people to build strong friendships and a strong sense of self．She also suggests the parents should encourage their kids to keep close to their friends, attend more interesting school activities and spend enough time with family．

    Parents should watch for signs of depression—eating or mood changes—and if they see signs from their daughters or sons, they need to give help. The good news is that the connection between romance and depression seems to become weak with age．Love will always make us feel young，but only maturity （成熟） gives us a chance to avoid its bad side effects．

    Fourth-grade teacher Tori Nelson allowed one of her students to shave her head in the schoolyard, after bullies（仗势欺人者） teased him about his own buzz cut. Ms. Nelson got the idea after noticing that Matthew Finney, a shy boy from her homeroom at Winlock Miller Elementary School in Washington State, was standing outside his classroom crying and wearing a winter hat.

    Ms. Nelson could see the back of his neck had been shaved, and since Matthew usually had very thick curly brown hair, she realized that he'd had a haircut over the weekend. She asked him what was wrong， and he said he'd gotten a buzz cut for the summer. But this morning, a fifth grader on the bus made fun of him, and he didn't want to come to class and get laughed at by other kids. Ms. Nelson tried to convince Matthew to come inside, but since school rules banned kids from wearing hats indoors he refused—explaining that he was afraid of showing his haircut to the other children in case they also made fun of him.

    "Finally I said, 'If you take your hat off and come to class, I'll let you give me a buzz cut too,' Ms. Nelson told Yahoo Parenting." I figured it's just hair, and mine is already short anyway. I might as well get it shorter in time for the warm weather.

    Matthew excitedly took her up on the offer, and Ms Nelson and another teacher gathered all the fourth graders together during break time. A school employee brought in scissors, which Matthew used to the cheers of his classmates, excitedly watching as their teacher's hair fell away onto the ground in the schoolyard.

    "It was a lot of fun for the kids, and it helped Matthew feel better about himself." said Ms Nelson." You have to do what it takes to reach children. Teaching isn't just about reading and writing: it's about self-worth and accepting differences.

    Many of us love July because it's the month when nature's berries and stone fruits are in abundance. These colourful and sweet jewels form British Columbia's fields are little powerhouses of nutritional protection.

    Of the common berries, strawberries are highest in vitamin C, although, because of their seeds, raspberries contain a little more protein (蛋白质), iron and zinc (not that fruits have much protein). Blueberries are particularly high in antioxidants (抗氧化物质). The yellow and orange stone fruits such as peaches are high in the carotenoids we turn into vitamin A and which are antioxidants. As for cherries (樱桃), they are so delicious who cares? However, they are rich in vitamin C.

    When combined with berries of slices of other fruits, frozen bananas make an excellent base for thick, cooling fruit shakes and low fat "ice cream". For this purpose, select ripe bananas for freezing as they are much sweeter. Remove the skin and place them in plastic bags or containers and freeze. If you like, a squeeze of fresh lemon juice on the bananas will prevent them turning brown. Frozen bananas will last several weeks, depending on their ripeness and the temperature of the freezer.

    If you have a juicer, you can simply feed in frozen bananas and some berries or sliced fruit. Out comes a "soft-serve" creamy dessert, to be eaten right away. This makes a fun activity for a children's party; they love feeding the fruit and frozen bananas into the top of the machine and watching the ice cream come out below.

    Polish President Andrzej Duda has signed a bill into law that largely limits trade on Sundays, saying it will benefit family life.

    The legislation（立法）, worked out by the government and the Polish trade union, is expected to draw protests from large western supermarket chains that are the main target of the law. A large part of their profit is earned on weekends.

    As of March 1, shops and markets are closed on two Sundays per month; in 2019 only one Sunday a month will be open for shopping; and starting in 2020, there will be no Sunday shopping with a few exceptions.

    Duda praised the law as giving children a chance to be with parents and giving shop workers some needed time off. He also said big traders will need to adjust their practices to the new system and asked them for "understanding". But critics say some of them make employees work long hours for modest pay.

    "A family should be together on Sundays," Olszewska said after buying some food at a local Biedronka, a large discount supermarket chain. She said that before she retired she served cold cuts in a grocery store, and was grateful she never had to work on Sundays.

    There are some exceptions to the ban. For instance, gas stations, cafes, pharmacies and some other businesses are allowed to keep operating on Sundays.

    Anyone breaking the new rules faces a fine of up to 100,000 zlotys （$ 29,500）, while repeat offenders may face a prison sentence. Polish trade union appealed to people to report any violators to the National Labor Inspectorate, a state body.

    We talk continuously about how to make children more "resilient(有恢复力的)", but whatever were doing, it's not working. Rates of anxiety disorders and depression are rising rapidly among teenagers. What are we doing wrong?

    Nassim Taleb invented the word "antifragile" and used it to describe a small but very important class of systems that gain from shocks, challenges, and disorder. The immune system is one of them: it requires exposure to certain kinds of bacteria and potential allergens(过敏源)in childhood in order to develop to its full ability.

    Children's social and emotional abilities are as antifragile as their immune systems. If we overprotect kids and keep them "safe" from unpleasant social situations and negative emotions we deprive(剥夺)them of the challenges and opportunities for skill-building they need to grow strong. Such children are likely to suffer more when exposed later to other unpleasant but ordinary life events, such as teasing and social rejection.

    It's not the kids fault. In the UK, as in the US, parents became much more fearful in the 1980s and 1990s as cable TV and later the Internet exposed everyone, more and more, to those rare occurrences of crimes and accidents that now occur less and less, Outdoor play and independent mobility went down; screen time and adult-monitored activities went up.

    Yet free play in which kids work out their own rules of engagement, take small risks, and learn to master small dangers turns out to be vital for the development of adult social and even physical competence, Depriving them of free play prevents their social-emotional growth. Norwegian play researchers Ellen Sandseter and Leif Kennair warned: "We may observe an increased anxiety or mental disorders in society if children are forbidden from participating in age adequate risky play."

    They wrote those words in 2011. Over the following few years, their prediction came true. Kids born after 1994 are suffering from much higher rates of anxiety disorders and depression than the previous generation did. Besides, there is also a rise in the rate at which teenage girls are admitted to hospital for deliberately harming themselves.

    What can we do to change these trends? How can we raise kids strong enough to handle the ordinary and extraordinary challenges of life? We can't guarantee that giving primary school children more independence today will bring down the rate of teenage suicide tomorrow. The links between childhood overprotection and teenage mental illness are suggestive but not clear-cut. Yet there are good reasons to suspect that by depriving our naturally antifragile kids of the wide range of experiences they need to become strong, we are systematically preventing their growth. We should let go-and let them grow.
