A new camera made by a company named Netatmo has facial recognition software(识别系统)that can tell parents at work that their children have returned from school, or that a package has been taken to their home. It can also tell them if a stranger has entered their home.

    Janina Mattausch is a product marketing manager for Netatmo.

    “The common security(安全)cameras at present are not that smart. So, they can tell you if something is moving but they don't necessarily know if it's a human being or, ah, if it's your kids—they don't' know the difference, so they will warn you all the time.”

    When family members enter a home,  the new camera "recognizes" (识别 )  them and sends information to the owner's smartphone. The owner can choose to see the video then or later.  But if an unknown person enters a home, the camera will send the owner a warning that will cause an alarm to sound on the owner's smartphone.

    That is what happened recently to a smart home camera owner named Darrmen. He lives in Paris.

    "On a Friday I was at work, attending a big monthly meeting when my phone warned. At first I told myself 'Oh, it must be a mistake, maybe I have to set the system again. “But the notice on my phone was telling me that there was a movement in my flat and also a face that the software did not recognize.”

    He watched the video and was very surprised by what he saw.

    "I saw a person I did not know with his shoes on. I was watching it live on video. So I felt totally unbelievable, frozen. I asked a workmate to take me back home as fast as possible and I called the police on the way. "

    With the help of the video,  the police found the intruder (闯入者) later that day.

Visiting Joshua Tree National Park, California

    Joshua Tree National Park is nearly 800,000 acres (英亩) large and surrounds parts of the Mojave and Colorado Deserts in South-central California. Although barren at first sight, the park is full of wildlife and provides a variety of entertainment activities from hiking to climbing. Within a three-hour drive, Joshua Tree National Park takes at least a full day to visit.

Things to do

    Hiking opportunities within the park include several choices, from 12 self-guided nature routines to all-day back-country hikes.

    Joshua Tree NP has nine camping grounds, and back-country camping is also allowed.

    Rock climbing is a popular activity in the park, which has 10 mountains greater than 5, 000 feet in height.

When to visit

    Joshua Tree NP is open 365 days a year, although the best time to visit is October through April, when temperature is milder. The peak season is when the wild flowers bloom, and the summer months are the least crowded.

What to bring

    In addition to your camera and telescope, be sure to carry lots of water. Park and guiding maps can be picked up at any of the three visitor centers.

Fees

    Parking fees: You can buy a seven-day vehicle permit (周票) for $ 15, a single entry permit for $ 5, or Joshua Tree National Park annual (每年的) pass for $ 60.

Camping fees: They vary by camping ground

    Everyone's at it, even my neighbors. I thought I might be the only person left in the world who hadn't done an eBay deal. So, I decided to try my hand at online Auction（网上拍卖）.

    Buying for Beginners

    Sign up on www.eBay.co.uk. Most items （e.g. tables, computers and books）ready for auction will come with a picture and a short description; others may be marked with Buy It Now and have a fixed price. You can buy these right away.

    If the item is being auctioned, you offer the highest price you are prepared to pay and eBay bids（出价）for you. The bid will be increased little by little until it goes beyond your highest bid, then you are emailed and asked if you would like to bid again. Auctions last up to 10 days and when they finish, you get an email telling you whether you have won the item.

    How to Pay

    Sellers decide how they would like to be paid and you need to check this before placing a bid as you might not want to post a check or postal order （邮政汇票）. The easiest way is through PayPal, an online payment system that takes the money away from your credit card.

    Selling Made Sample

    If you plan to sell on eBay, it helps to include a picture of the item. I followed my friend's advice and put up the items I wanted to sell for a 10-day auction, starting on a Thursday. This way buyers had two weekends to bid.

    The Big Things in Life

    It's easy to post a small item, but furniture is a big part of eBay and this has to be collectively sent by deliverymen. Check the ways of delivery before you bid.

    Family fights are never pleasant. Whether you are dealing with a loud sister or a stubborn mom or dad, the situation can be bad. At least that's what we have learned to expect.

    What if it could be different? What if family fights and conflicts could be turned into opportunities to become closer? What if problems could be solved with everyone walking away feeling more deeply cared for and loved?

    Family fighting is, on one level, about power. Someone is telling someone else what to do. In a short moment, emotions can be brought out and the fight is on. You can go down that old road or you can try something different.

    In any fight, you have a need to be listened to and understood. People raise their voices and shout at each other because they're not being listened to. It's totally unconscious. You want your mom or dad to listen and understand. But you always seems to forget the person you're fighting with has the same need to be listened to. So if you can put aside your need for a few minutes, the situation will change quickly. Give the other person some time to express his or her feelings, and you will earn your turn to be listened to.

    And while you are listening, you have to listen for the right information. The best way to do this in emotional situations is to forget most of the words because many people can't express what they are feeling with words alone, especially when they are upset.

    But if the situation starts to get out of hand, it would be wise to just calm down and leave the problem until later because many fights happen at the wrong time. The situation will die down quickly, usually in less than 30 seconds. You can either move on to problem solving or reach an agreement to work on it at a better time.

    This way, everyone will feel respected and listened to, even when there is conflict. Emotions will be understood and respected, and it will bring your family closer together.

    Why does night fall but never break and day break but never fall？Why are people who ride motorcycles called bikers and people who ride bikes called cyclists？In what other language do people drive in a parkway and park in a driveway？In what other language do they call the third hand on the clock the second hand？

    Let's face it: English is a crazy language. There is no egg in an eggplant, neither pine nor apple in a pineapple and no ham in a hamburger. Sweet-meats are candy， while sweetbreads, which aren't sweet, are meat.

    We take English for granted. But when we explore its paradoxes(悖论), we find that quicksand can work slowly, boxing rings are square, public bathrooms have no baths in them.

    And why is it that a writer writes, but fingers don't fing, grocers don't groce, and hammers don't ham？If the plural of tooth is teeth, shouldn't the plural of booth be beeth? One goose, two geese - so one moose, two meese?

    How can a slim chance and a fat chance be the same, while a wise man and a wise guy are opposites? How can overlook and oversee be opposites, while quite a lot and quite a few are alike? How can the weather be hot as hell one day and cold as hell the next？

    English was invented by people, not computers, and it shows the creativity of human beings. That's why, when stars are out, they are visible; but when the lights are out, they are invisible. And why, when I wind up my watch, I start it; but when I wind up this essay, I end it.

Inventor James West was born in 1931 in Virginia. As a child, he spent lots of time studying how things worked and enjoyed taking apart small machines. "If I had some tools, any small machines that could be opened were in danger," West said. "I had a strong desire to know what was inside. "

After an accident with a radio, West paid special attention to electricity. But his parents were concerned about the future job for an African-American scientist. They preferred him to become a doctor. However, West headed to Temple University in 1953 to study physics. Because of his school performance in physics, he managed to get training during the summer at Nokia Bell Labs, a world-known American industrial research and scientific development company. He received a college degree in physics in 1957, and upon graduation, he became a worker at Nokia Bell Labs.

In 1960, while at Bell, West teamed up with scientist Sessler to develop a less expensive, more powerful and smaller microphone (麦克风), In 1962, they finished the development on the product. Their invention became the industry standard. And even today, 90 percent of microphones — for example, found in telephones, tape recorders, baby monitors and hearing aids — are based on their technology.

West was chosen as Inventor of the Year by the state of New Jersey and president of the Acoustical Society of America. And both West and Sessler were chosen into the National Inventors Hall of Fame.

West left Bell in 2001. After some interviews with several universities, he chose the Johns Hopkins University and became a research professor at its Whiting School of Engineering. "I discovered that Johns Hopkins was a lot like Bell Labs, where the doors were always open and we were free to work with researchers in other areas," he said. "I like the fact that I won't be locked into one small closed room here. "
