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.”

    Maybe you have ever seen a cross. A cross can be a piece of jewelry or an image in a painting. But do you know the cross is a very popular symbol for Christmas？

    It came from the story of Jesus' death on the cross two thousand years ago in Jerusalem. Jesus was Jewish，and at that time Jewish people were under Roman rule. Jesus was badly punished because he declared to be the Son of God and the King of Jews. Surely，the Son of God could have saved himself from the death！But the Bible says that Jesus had a reason to die that day. It was in God's purpose that it would happen.

    Christians call the day that Jesus died “Good Friday”. At first，it is hard to understand how a terrible day could ever be called good. Well，the story does not end there. Jesus died and he was buried. But three days later，Jesus was alive，and the whole world was changed.

    Today，Christians everywhere remember this important time. They celebrate Easter. Easter is the day that Jesus rose from the dead. After his death on the cross，Jesus' body was placed in a tomb. On the third day from then，God raised him from the dead. Jesus stayed on earth physically for several weeks. Many people saw him. Easter is the happiest time of year for Christians because they believe that Jesus had victory over death and evil and that now he lives with God the Father in heaven. But before celebrating Easter, Good Friday should be remembered. Jesus died a horrible and painful death. He suffered, though he did nothing wrong. Christian believe that Jesus was God's substitute(代表) for humans， because humans all do wrong. He died because of humans and he died for humans.

    Christians often wear crossed around their necks of hang them in their homes because they believe it is a very important sign. The cross helps them remember how much God loves them. It helps them remember how much his Son had to suffer. Seeing a cross always makes them think of Jesus' death， and what it means.

    Like a tired marriage, the relationship between libraries and publishers has long been dull. E-books, however, are causing heartache. Libraries know they need digital wares, but many publishers are too cautious about piracy (盗版）and lost sales to co-operate. Among the big six, only Random House and Harper Collins license e-books with most libraries.

    Publishers are wise to be nervous. Owners of e-readers (电子阅读器）are exactly the customers they need: book-lovers with money. If these people switch to borrowing e-books instead of buying them, what then? Electronic borrowing is awfully convenient. Unlike printed books, which must be checked out and returned to a physical library miles from where you live, book files can be downloaded at home. The files disappear from the device when they are due.

    E-lending is not simple, however. There are lots of different and often incompatible (不兼容的)e-book formats, devices and licenses. Most libraries use a company called OverDrive，which secures rights from publishers and provides e-books and audio files in every format. Yet publishers and libraries are worried by OverDrive's global market dominance, as the company can control fees and conditions. Publishers were annoyed when OverDrive cooperated with Amazon, the world's biggest online bookseller，last year. Owners of Amazon's Kindle e-reader who want to borrow e-books from libraries are now redirected to Amazon's website, where they must use their Amazon account to secure a loan.

    According to Pew, an opinion researcher, library users are a perfect for market for Amazon. Late last year Amazon introduced its Kindle Owners' Lending Library, which lets its best customers borrow free one of thousands of popular books each month.

    Library supporters argue that book borrowers arc also book buyers and that libraries are vital spaces for readers to discover new work. Many were cheered by a recent Pew survey, which found that more than half of Americans with library cards say they prefer to buy their e-books.

    So publishers keep adjusting their lending arrangements in search of the right balance.

    Random House raised its licensing prices earlier this year, and Harper Collins limits libraries to lending its titles 26 times.

Elephants might be the most well－known and well－loved animal in African wildlife. But conservation (保护) of the African elephant faces special difficulties. While the elephant population is half of what it was 40 years ago, some areas of Africa have more elephants than populated areas can support. That's why AWF scientists are studying elephant behavior, protecting habitats and finding ways for humans to live peacefully with elephants in Africa.

Years ago, overhunting and the ivory trade were the biggest threats to elephants' survival. Luckily, ivory bans (禁令), hunting rules and protected areas protect elephants from these dangers today.

The 21st century brings a different challenge to elephant conservation—land－use. Elephants walk across borders and outside parks and other protected areas. So they often destroy crops, causing conflicts (冲突) between local farmers and these big animals.

Successful conservation strategies (策略) must allow elephants to walk freely in their natural habitats while reducing conflicts between elephants and local people.

AWF researchers are searching for a way to give both elephants and people the space they need. The AWF is collecting information on elephant habitats and behavior. The information they gather will help to develop the widest possible space for elephants.

The AWF is helping elephants by protecting their habitats. And they also work with local farmers to improve their life in order to encourage them to protect rather than destroy elephants.

After releasing a short video on April 27 about planting and cooking peas, Chinese food blogger Li Ziqi witnessed her followers on YouTube go beyond 10 million.

This puts Li, who shot to fame with short videos recording her traditional and peaceful lifestyle in China's countryside, among the ranks of the most popular Chinese-language content creators on the platform.

"It's really surprising. I didn't expect such a wide response," Li told Xinhua in an interview, noting she was surprised by how foreign fans were taken with her works. "What I present is just a lifestyle I've long followed and appreciated," she said. "Maybe it's also what many other people have valued."

Li's YouTube videos center on her life with her grandmother in the rural parts of Sichuan Province. In the videos, Li, often dressed in graceful traditional dresses, rises at sunrise, rests at sunset, plants seeds and harvests flowers, cooks Chinese dishes and crafts bamboo furniture. Unlike many other food bloggers, Li's videos set China's countryside as the stage and start with how the foods are planted and harvested on the farm. She rarely speaks in the process.

Li's overseas followers have praised her videos for showing the amazingly charming, simple and beautiful side of China's rural life, but back home, there have long been debates on whether her presentation is unrealistically poetic.

In response, Li, who was raised in the countryside, said she never needs special arrangements when shooting a video about rural life as "everything is in my mind." "In the countryside, planting flowers, vegetables and trees is not difficult. There are tough elements of rural life of course, but I didn't put them in my videos," Li said. "Most people today are facing much stress in work and life, so I hope they can feel relieved and relaxed when watching my videos."
