One of the most popular vacation destinations for young families is the home of relatives. {#blank#}1{#/blank#}  Here are some tips for making sure you are invited back again.

    Be considerate

    Every family has their own way of doing things. Keep these things in mind when you're visiting.

    If your host family are early to bed and early to rise, don't keep them up talking until one o'clock in the morning.

    If your host family gets angry about kids running wild, either plan to keep a close eye on your kids or plan to stay somewhere else. {#blank#}2{#/blank#} 

    Offer to help out

    Playing host to a family with children can be quite a challenge. Make sure you help lighten the load.

    {#blank#}3{#/blank#} Offer to help with cooking and cleanup. Make your beds and run to the store for milk. Better yet, don't ask. Just start working.

    Help pay for food

    This may not apply, if you're visiting parents and they insist on paying for everything and they can afford it. {#blank#}4{#/blank#}  Use your judgment when it comes to parents. However, if you're visiting cousins, it will be a great help to them if you buy your  share of the food.

    Show your appreciation

    No matter whom you are visiting, make sure you let them know you appreciate their hospitality(盛情招待). {#blank#}5{#/blank#}  Or leave some fresh flowers when you leave. If you don't have enough money, write them a letter, letting them know how much fun you had and how much you appreciate them.

A．Don't expect your hosts to supply your every need.

B．Offer to take them out to dinner on your last night in town.

C．Make sure you don't leave your things behind while visiting a family.

D．In that case you may hurt your parents if you insist on paying for food.

E．Try not to disturb someone who is in the middle of exams.

F．Staying with relatives is a great way to save money while getting away from home for a while.

G．Having a talk with your children about expected behavior while visiting is always a good idea.

To be successful people

    Here are some opinions about successful and unsuccessful people.

    Make life plans and set goals

    You can't be successful without knowing where you are going. A life vision board, 10 years' plan and daily goals are useful tools of the successful people. {#blank#}1{#/blank#}

    Keep a "To-be" list for the future

    A "To-be" list is a great way to plan for the future. I want to be an elected official in the future. I want to be the CEO of a public company. {#blank#}2{#/blank#} Unsuccessful people have no idea what they want to be. How can you achieve success if you don't know what you want to be?

    Study every day

    {#blank#}3{#/blank#} Whether you are reading a magazine or a good book. You can learn and become knowledgeable as you read. While watching television may be good entertainment, you will hardly get anything out of TV to help you become more successful.

    Want others to succeed

    When you are in an organization with a group of people, in order to be successful, you all have to be successful. {#blank#}4{#/blank#} If you wish for their failures, why even work with them at all?

    Accept responsibly for your failures

    Where there are ups, there are most always downs. Being successful persons means always having to accept responsibly for your failures. {#blank#}5{#/blank#} It just puts other people down and no good comes from it.

There are a number of steps you can take before making a final decision.{#blank#}2{#/blank#} If you enjoy marine life, for instance, you should consider a marine biology major. If you love star-gazing, consider becoming an astronomer.

    Next, consider the academic subjects in which you excel(优秀). If you're not strong in math you might be better off not choosing engineering. If you are good at English you might choose to become an author or a journalist.{#blank#}3{#/blank#}

    Once you've established a list of potential career fields, research them further to determine which college majors are most proper. Then you can get an idea for what courses you'll need to take.{#blank#}4{#/blank#}

    PhoneSoap: Charge and Clean Your Phone

    You may charge your phone every day, but do you clean your phone as much? Whatever your hands touch, your phones touch. It has been discovered that some phones have 18 times more bacteria and viruses than any surface in a public restroom. So it probably won't surprise you that a 2011 University of London study found that one in six of our phones have bacteria and viruses on them—specifically, the bacteria called E. coli.

    The research on bacteria and viruses led to the invention of PhoneSoap. It is not actually liquid like dishwasher soap. It is a phone charger that uses the electromagnetic radiation (辐射) used in hospitals to kill 99.9 percent of bacteria and viruses, cleaning your phone while it charges.

    “There are really certain types of bacteria and viruses that we should not be in touch with, and they are really on our phones,” says Wes Barnes, the PhoneSoap co-founder. It all started while his cousin and co-founder, Dan LaPorte, was in his cancer research lab at college. “He realized he got the idea of getting rid of bacteria and viruses on the phones,” said Barnes. “In the lab they used UV-C light for destroying them. He realized this would be the fastest, most powerful way to kill any bacteria and viruses living on electronic machines.”

    PhoneSoap looks like a little metal suitcase. Your phone rests in to charge and get cleaned at the same time. Instead of plugging your phone into the wall, you'd plug it into the PhoneSoap charger box. The process only takes a few minutes but, Barnes says, “The idea is that you can leave it in there overnight if you want to keep charging. Reflective paint keeps the light completely around the phone so it cleans the phone fully.”

    The co-founders spent 2013 finding the right companies and they started shipping the product in late November. By last week's International Consumer Electronics Show in Las Vegas, PhoneSoap was all grown-up. Both co-founders have left their previous jobs and are selling PhoneSoap nonstop. “We're shipping almost more than we can handle each day,” Barnes says. “It's been a great adventure.”

    That people often experience trouble sleeping in a different bed in unfamiliar surroundings is a phenomenon known as the 4Tirst-nighf, effect. If a person stays in the same room the following night they tend to sleep more soundly. Yuka Sasaki and her colleagues at Brown University set out to investigate the origins of this effect.

    Dr. Sasaki knew the first-night effect probably has something to do with how humans evolved.

    The puzzle was what benefit would be gained from it when performance might be affected the following day. She also knew from previous work conducted on birds and dolphins that these animals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators (捕食者). This led her to wonder if people might be doing the same thing. To take a closer look, her team studied 35 healthy people as they slept in the unfamiliar environment of the university's Department of Psychological Sciences. The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found, as expected, the participants slept less well on their first night than they did on their second, taking more than twice as long to fall asleep and sleeping less overall. During deep sleep, the participants' brains behaved in a similar manner seen in birds and dolphins. On the first night only, the left hemispheres (半球) of their brains did not sleep nearly as deeply as their right hemispheres did.

    Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding environment, Dr. Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularly timed beeps (蜂鸣声) of the same tone and irregular beeps of a different tone during the night. She worked out that, if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found.
