Think twice the next time you decide to copy your boss in an email. That simple little “CC” box (抄送框) could send a message that ruins your relationship with the other receivers.

    A study in Harvard Business Review asked working adults to imagine that their coworker always, sometimes, or rarely CC'ed their boss in emails. The study results show that employees felt less trusted when their coworker “always'' copied the boss than when they ''sometimes” or “almost never” did. The results of the survey aren't surprising, says career expert Bruce Tulgan. Sometimes the boss really does need to stay in the loop (在圈内) with an email chain. But most times, employees are purposely sending the message that they don't think the receiver follow through with what they're asking unless the boss gets involved, says Tulgan. “That is an expression of lack of trust,'' he says.

    Breaking down that trust level in your office can have serious consequences. Like in any relationship, coworkers need trust to keep things running smoothly. “When people have trust, there is a much higher level of wanting to deliver for each other,” says Tulgan. “When people have enthusiasm, they try harder.” That means more willingness to take risks and make decisions, he says. Even if you don't trust your coworker to follow through for you, copying the boss in an email is not the best strategy, says career expert Todd Dewett, PhD. “CC'ing is the adult version of being a tattletale (告密者),” he says. “It tells your colleague you didn't agree without telling it to their face, and you want your boss to know without talking about it.”

    As a rule of thumb, only about 20 percent of what you do in the office is truly urgent, and those are the only times you should consider getting your boss involved in, says Tulgan. “The most important people, the most important project, key relationship,” she says. “That's when you might consider the occasional use of CC.”

    Last year, Claire Noble-Randall woke up at 5:30 am every morning. She had to catch two buses to arrive in time for first-period chemistry at Ingraham High School in Seattle, US.

    Ingraham starts at 8 am, but Noble-Randall often didn't go to sleep until after midnight. “It was really hard not to fall asleep in class,” she said.

Her mom solved the problem this year when she discovered that other parents had hired a private city tour bus to take their children to the school.

    “Now, she leaves the house at a much more reasonable time 7:10 in the morning…to catch the little tour bug at 7:23 am,” said her mother, Noelle Noble.

    That may be one way to help students get more sleep. But more than 3,300 people have signed an online petition (请愿) looking for a better solution from the Seattle school district. Those who have signed the petition want all high schools and middle schools to start no earlier than 8:30 am. Most of Seattle's high schools and middle schools start at 8 am or earlier.

    Later start times for teenagers is an idea that some parents around the nation, have wanted for years. They've provided plenty of scientific evidence that teenagers tend to be night owls and delayed start times improve their health, mood, attention, and, in some cases, learning.

    But attempts to delay start times for teenagers haven't worked. Coaches don't want late dismissals (放学) cutting into sports practices; community groups don't want to wait longer for gyms and fields and before- and after-school programs don't want to change their schedules.

    This time, however, they've got Seattle School Board. President Sharon Peaslee on their side. She herself is the mother of two high school students. Peaslee hopes other board members will pass her plan calling on the district to find a way to make the changes.

    Your local grocery store is a psychological minefield (布雷区), where even the bananas are ripe with mystery.

    ⒈Southpaws (左撇子) have an invisible advantage

    You've probably seen that stores keep go-to items produce, meats, dairy on the outer edge. But did you notice that most of them are set up to make you run counterclockwise (逆时针)? Ninety percent of us are right-handed, so we buy more when it's counterclockwise. You'll also often find the dairy section in the back-left corner: Because dairy is likely on your list, stores make sure you take the longest route to get there. In fairness, it's also a more convenient place to put a fridge.

    ⒉Everything is in its place

    It's safe to say that nothing you see on a shelf is there by chance. The cookies on sale at the end of a passage are likely the result of smart product placement. More expensive items are usually placed at an adult's eye level, while colorful treats and other products for kids are positioned lower to catch the attention of children.

    ⒊Time goes by so slowly

    Stores rarely have windows or clocks. With no reference to the outside world, customers can easily lose track of how long they've been there so that they can buy more. Grocery stores may use another trick to control your sense of time: small floor tiles (瓷砖).

    Red leaves are a symbol of autumn. Enjoying red leaves in the clear, refreshing autumn weather is indeed a good choice.

    Now let's have a look at the best red leaves around China and the beauty of autumn.

    Destination 1

    With different red colors, the Red Leaf Valley extends (延伸) more than 50 kilometers from Jiefang village in Qingling town to Yanjiang village in Songjiang town, Jilin province, Northeast China. Leaves are like different red pigments (颜料), including Chinese red, orange red, ruby red and bright red.

    Best time: October

    Destination 2

    Tachuan or Tashang village is in Huangshan city, Anhui province, East China. The beautiful autumn scenery there is known as one of the four best in China. The red leaves and clear spring add beauty to traditional houses, offering material for photography lovers.

    Best time: early to late November

    Destination 3

    As a result of low temperatures, maple leaves in areas south of the Yangtze River are like shy girls, gradually showing their beauty, turning from green to gold, gold to orange and finally to red. And as it changes slowly, different colors can be seen on the same trees called "colorful maple trees". Viewing at the mountainside is the best choice.

    Best time: October to November

    Destination 4

    For Guangdong province in South China, autumn always comes a little late and lasts longer. Through the end of January, you can see the red leaves any time you want. If you feel pity at saying good-bye to red leaves in North China, you can head to South China to view the beautiful scenery again.

    Best time: end of November to end of January

    Most of us might only begin to think about dinner in the late afternoon: What should I make today? But Jelena Petrovic begins to think about her big meal early each morning. After morning tea, she and her husband, Milan, begin their plans for a traditional Serbian dish. The cooking method they use probably comes from Jelena's mother or grandmother. Each recipe uses local foods found in Serbian markets.

    Milan goes to the market to get the food they need. And the 69-year-old Jelena makes plans for how she will explain the cooking process to her 150, 000 followers on YouTube. Once she is ready, Jelena films her cooking show from a small kitchen table. Milan holds the camera.

    Jelena has many years of cooking experience at home. Ten years ago, she started an online program, where she shared recipes and cooking suggestions for meat, soup, bread, sweet treats and more.

    Her number of followers grew over time. She decided to start a blog and began also making videos she filmed with her mobile phone. Today, her videos on YouTube have over 50 million views. Last year, "Granny's Kitchen" was named one of the Top 50 YouTube channels in Serbia.

    Now her YouTube channel takes up much of her day. She works from her small kitchen and home office. Colorful plants and flowers fill the room. A bright cloth covers the table where she works. She says she gets tired from cooking long hours each day. But, she said, "My viewers wait for a new recipe every morning. If I am late, they will ask if I am well or what is happening."

    Often, her viewers write that the recipes bring back happy memories of their childhood. "My recipes are all local, traditional home-food recipes," Jelena said. "I make things my mother or grandmother used to make."
