Vacation is a time for refreshment. In work, we are often called to think. Sometimes, it's good to give our brains a rest. Without a break, we may not be able to perform up to our potential. This can be a problem, not only for the employee, but for the employer as well.

    “The main benefit of vacation is for the worker to come back energized,” says Weaver. “If they haven't had a break, then they're not coming back with new energy. They haven't had a chance to step back and get perspective (远景), and come back with renewed enthusiasm.”

    Long working hours without a break, insecurity (不安) about one's job, and other work-related worries can lead to burnout and stress. Humans can usually adapt to pressure, but not for a limitless amount of time.

    “It is a problem of relating good workers and having them loyal to the firm while they're there,” says David Maume, PhD, professor of sociology at the University of Cincinnati. He says burnout can also affect employees' productivity, creativity, and effectiveness.

    In addition, high levels of stress are likely to be precursors (前兆) to depression, which can hit both the employer and employee's pocketbook. Even people who manage to remain productive at work can have problems. If they're always at work, then they're not with their family and friends. If they're working while on vacation, for the time that they're on the job, they're not really present.

    An unbalanced emphasis on work can strain family and social life. When you come up for air, you may see that you're alone, or that your relationships have gone on without you.

    A creative mom Danielle Lindemann is a mother to a soon-to-be 3-year-old daughter. When she received the Disney-brand book What Is A Princess? as a gift for her daughter, Lindemann thought the messages seemed a little shallow.

Lindemann's efforts included changing “A princess is kind” to “A princess is kind of a badass” and completing the sentence “A princess likes to dress up”. “I just want my daughter to see that she can be anything she wants,” the mom explained, “She can also speak her own mind and be a doctor or a senator if she wants.”

    After Lindemann made the changes, she thought her daughter might be a bit confused, but the daughter actually just rolled with it. Lindemann did not intend for many people to see her edits. She just found it amusing. Though she didn't imagine having such a wide audience, Lindemann says she thinks it's great if her edits make people smile or even think a bit differently about gender models.

    Further, Lindemann added, “there is absolutely nothing wrong with girls (or boys!) wanting to put on something sparkly and feel pretty. But when the ruling idea is that girls — and women — are judged mainly on their physical appearance in a way that boys and men are not, I think it's important to model some other values for these girls as well.”

    As a parent, she believes it's important to show girls that their worth does not lie only in their physical appearance and that their other qualities are valuable and important. For her, if there were a variety of children's books out there in which little girls were shown playing with trucks and trains and learning to be engineers and surgeons, and if there were books out there in which boys were shown getting a kick out of dressing up in fancy clothes, it would be a different world.

     “At present, it's not that world. But time will tell,” she stressed.

    Bandhavgarh National Park in India is best known for its amazing setting, as well as having the highest concentration of tigers in India. In addition to tigers, there are also bears, deer, wolves, birds, etc.

    Location: In Madhya Pradesh state, almost 200 kilometers northeast of Jabalpur. The nearest village is Tala, which is the access point of the park.

    Opening Hours and Safari (游猎) Times

    Safaris operate twice a day, starting at dawn until late morning, and mid afternoon until sunset. The best time to visit the park is early in the morning or after 7 p.m. to spot the animals. The park is closed from July 1 to September 30 due to the monsoon season (季风季节).

    Bandhavgarh Zones

    Bandhavgarh is divided into three main zones: Tala (the park's best zone, with the most tigers), Magdhi (the second best zone to see tigers), and Khitauli (scenic and less visited, although tiger sightings do occur there; particularly good for birding).

    Entry Fees and Charges for Jeep Safaris

    Bandhavgarh has become expensive to visit in recent years. Entry fees have increased since October 2014. When going on a safari, separate fees must be paid for park entry and jeep hire. Entry tickets are priced per vehicle (up to six people). For 2015-16, park entry tickets cost as follows:

    ·Tala Zone: 2,400 rupees for Indians, 4,800 rupees for foreigners. (Up to six people)

    ·Other Zones: 1,200 rupees for Indians, 2,400 rupees for foreigners. (Up to six people)

Jeep Hire

    Expect to pay about 2,200 rupees to hire a jeep, in addition to the entry cost. This can be done at the park entrance. All hotels can arrange jeep hire and tours, but at a higher rate. It's much less trouble though. Besides, unlike many national parks in India, it's possible to take private vehicles into Bandhavgarh.

    All over the world people enjoy sports. Sports help to keep people healthy and happy, and to live longer.

    Many people like to watch others play games. They buy tickets or turn on their TVs to watch the games. Often they get very excited when "their" player or team wins.

    Some sports are so interesting that people everywhere go in for(参加) them. Football, for example, has spread(展开)around the world. Swimming is popular in all countries near the sea or in those with many rivers. What fun it is to jump into a pool or lake, whether in China, Egypt or Italy! And think of people in cold countries. Think how many love to skate or ski (滑雪) in Japan, Norway or Canada.

    Some sports or games go back thousands of years, like running or jumping. Chinese wushu, for example, has a very long history. But basketball and volleyball are rather new. Neither one is a hundred years old yet. People are inventing new sports or games all the time. Water-skiing is one of the newest in the family of sports.

    People from different countries may not be able to understand each other, but after a game together they often become good friends. Sports help to train(培养,训练) a person's character(性格,品格). One learns to fight hard but fight fair, to win without pride and to lose with grace(胜不骄，败不馁).

    It's a real case of fish out of water. Blennies (鲇鱼) in the South Pacific Ocean are gradually relocating to land to escape their predators (捕食者), in an example of evolution in action.

    Fish first began crawling onto dry land about 400 million years ago, kicking off an evolutionary chain of events that led to humans. But their reasons for exiting the sea have been uncertain.

    To look for clues, Terry Ord at the University of New South Wales in Australia has been studying several species of blennies at Rarotonga, the largest of the Cook Islands.

    At low tide, blennies are commonly found swimming in rock pools around the edges of the island. But when high tide moves in, they climb up to dry land and move around the rocks until the tide retreats.

    The researchers found that this is most likely to avoid predators that swim in with the rising tide – mainly bigger fish like lionfish.

    To test what would happen if blennies did not have an escape plan, they made blenny models and sank them in the sea. The mimics ended up with wounds, bite marks and chunks-missing.

    Of course, there are still dangers for blennies on land, like the occasional bird attack, but the predation risk on land is a third that of underwater.

    What's more, moving onto land has additional benefits for blennies. Holes in the rocks provide sheltered nests for laying eggs, and they can maintain their diet of bacteria.

    In fact, several species of blenny fish at Rarotonga have already made the full transition to land-dwelling (陆生的) species. They continue to breathe with their gills, but have developed stronger tail fins and jump from rock to rock.

    Ord believes that many evolutionary processes have been driven by the need to escape predators. “It is often assumed that animals move homes to find new sources of food, but in many cases, escaping predators is a stronger motivation.” he says.

    Imagine you are opening your own company and want to hire a manager. You have two candidates and they are both capable and experienced, so who would you rather hire: Julia Watson or Shobha Bhattacharva? Chances are that you would prefer Watson, right? But why?

    "Easy names are evaluated as more familiar, less risky and less dangerous," Eryn Newman, a scientist at Victoria University of Wellington, New Zealand, told Scientific American. As a result, people with easier names are often assumed to be more trustworthy. This is what Newman and her teammates have found in their recent study.

    In the experiment, they picked 18 different foreign names, including difficult-to-pronounce ones like Yevgeni Dherzhinsky and easy names like Bodo Wallmeyer. They then attached each name with a statement such as "turtles are deaf" and "giraffes are the only mammals that cannot jump" and asked volunteers whether they thought the claims were true.

    The results showed that claims connected to easier names were more often ranked as believable than those attributed to difficult names, regardless of what the truth really was. In fact, previous studies have already found that our judgments about products can be affected by their names. For example, we tend to think of a food additive (添加剂) with an easier name as safer and a stock with an easier name as more lucrative (利润丰厚的)，according to Medical Daily.

    But researchers pointed out that this effect can change depending on where someone comes from. For example, a native British man may find "Yevgeni Dherzhinsky" hard to pronounce while Russian people could say it without effort. Newman hopes that this finding can make us better see our biases (偏见). It's not just unfair to people that we make judgments based on gut feelings (直觉) rather than facts, and it can sometimes have serious consequences.

    For example, we may choose to believe certain eyewitnesses in court simply because their names sound more trustworthy even if they are actually lying. Or, we may let go of qualified job candidates due to their "difficult" names.

    Now, if you could make that decision again, would you still prefer Julia Watson to Shobha Bhattacharva?
