The Owl Count

    Annie slept in the front of the seat with her father drovethrough the darkness. “We're almost there!” Dad announced cheerfully. “Soon we'll be observing and counting owls at the state park.” Yawning, Annie noddedand smiled. The time was 4:30 a.m. Looking out into the darkness, Annie remembered learning in school that most owls are active at night, when they hunt for food. During the day they sleep in hard-to-find spots.

    “Dad, why do you need to count owls?” she asked. “It's importantfor the scientists to have current information about bird populations,” he explained. “We want to know which birds have decreased in number and whether any new kinds of birds are coming into a certain area. You and I will write down the kinds of birds that we see today and keep a record of how many times we see each kind. Then we'll send out a report to a scientific organization that is collecting about birds from people all over the country.”

    Dad pulled into the parking lot of the state park. Then, with flashing in hand, they began their hike into the woods. Annie zipped up hercoat and tried to keep from trembling. She had not expected the morning to beso cold. Luckily her gloves were in her pocket.

    Suddenly Annie's father stopped and gestured for her to bestill. Obeying, Annie did not take another step. She thought she heard a low crying up head. “That's certainly a screech owl,” her father whispered. “Let's get a look at it.” After looking more closely, Annie could see that it was asmall owl. Sensing danger, the owl narrowed its eyes and pulled its feathers tightly against its body. Annie carefully wrote down in her notebook that theyhad seen a screech owl.

    Walking a little farther, they came to a tall oak tree. “Thislooks like a perfect spot to attract owls,” Dad said, “I'm going to play a recording of common call of the barred owl. Maybe we can get one to answer." Annie could hardly believe her ear. The recorded call sounded as if the birdwere asking, “Who cooks for you?” Moments later Annie thought she heard areturn call in the distance. She held her breath and waited. Suddenly a huge bird landed very quietly on a branch above them.

    Annie had long forgotten how cold it was. She stood in wonder, shining her flashlight on the bird and studying it carefully. The barred owl was nearly two feet tall. Grey feathers surrounded its dark eyes. The bird did not stay long, but it did not matter. Annie would never forget the image of the powerful barred owl.

    Alibaba opened China's version of Amazon's cashier-less store, “Tao Cafe” at its second annual Taobao Maker Festival taking place from 8—12 July, and then showed it to the public. By scanning a QR code（二维码）on Taobao app at the entrance of the store« consumers are tracked with cameras for facial recognition. After going through the checkout doors, customers will automatically make a purchase through their smartphones without needing to head to a register and be able to leave the store with what they buy in hand.

    The company, putting its efforts in Artificial Intelligence and data technologies, caused some ripples（波动）among offline retailers （零售商）. But if you think the e-commerce giant plans to get a slice of the physical-store pie, then you might get it wrong: “It's not about Alibaba wanting to open more cafes, we are not in the restaurant business.” it's about digitalizing the footprints of the visitors to an offline store, '' said Chris Tung, chief marketing officer of Alibaba Group.

    He said, for example, in the online world, Alibaba can always personalize every web page based on users interest and preference thanks to big data, “When you open our app, every moment is different.” But on the other hand, “offline is becoming not so exciting anymore”, because many physical stores are always found to be very similar with no variation.

    Tung said offline retailers could improve by adopting online data competence to link the identity of the customers» and optimize（优化）their in-store shopping experience. So in this sense, after physical stores have an understanding of what their customers need online, then they can allocate the products in the physical offline store accordingly. He further explained the pop-up Tao Cafe is one of the ways to present this “new retail” idea and opens up people's thinking and calls for more partnership.

    Terrafugia Inc. said Monday that its new flying car has completed its first flight, bringing the company closer to its goal of selling the flying car within the next year. The vehicle — named the Transition — has two seats, four wheels and wings that fold up so it can be driven like a car. The Transition, which flew at 1,400 feet for eight minutes last month, can reach around 70 miles per hour on the road and 115 in the air. It flies using a 23-gallon tank of gas and burns 5 gallons per hour in the air. On the ground, it gets 35 miles per gallon.

    Around 100 people have already put down a $10,000 deposit（定金） to get a Transition when they go on sale, and those numbers will rise after Terrafugia introduces the Transition to the public later this week at the New York Auto Show. But don't expect it to show up in too many driveways. It's expected to cost as much as $279,000. And it won't help if you're stuck in traffic. The car needs a runway.

    Inventors have been trying to make flying cars since the 1930s, according to Robert Mann, an airline industry expert. But Mann thinks Terrafugia has come closer than anyone to making the flying car a reality. The government has already permitted the company to use special materials to make it easier for the vehicle to fly. The Transition is now going through crash tests to make sure it meets federal safety standards.

    Mann said Terrafugia was helped by the Federal Aviation Administration's (联邦航空管理局) decision five years ago to create a separate set of standards for light sport aircraft, which are lower than those for pilots of larger planes. Terrafugia says an owner would need to pass a test and complete 20 hours of flying time to be able to fly the Transition, a requirement pilots would find relatively easy to meet.

    One of the most important things in the world is friendship. In order to have friends, you have to be a friend. But how can you be a good friend at school?

    Listen — Listen when they are talking. Don't say anything unless they ask you a question. Sometimes it's not necessary for you to have anything to say; they just need someone to talk to about their feelings.

    Help them — If your friend is ever in need of something, be there to help them. You should try to put them first, but make sure you don't do everything they want you to do. Try to take an extra (额外的) pencil or pen with you to classes in case (以防) they forget one. Have a little extra money in your pocket in case they forget something they need.

    Be there for them — Try to make something for your friend to help make them feel better in hard times. Making cards and encouraging them are among the nicest things you can do for a friend. Marilyn Monroe, a famous U.S. actor, once said, “I often make mistakes. Sometimes I am out of control. But if you can't stay with me at my worst, you are sure not to deserve (值得) to be with me at my best.” Always remember this! If you don't want to stay with your friends when they're in hard times, then you don't deserve to be with them when they're having a good time!

    Make plans — Try to make plans with your friends. Go shopping, go for ice cream, have a party, go to a movie and so on. Take time to know each other even better by doing something you both enjoy. By planning things together, you both can have a good time. And you'll remember these things when you're all old!

    A scientist once said: "I have concluded that the earth is being visited by intelligently controlled vehicles from outer space."

    If we take this as a reasonable explanation for UFOs (unidentified flying objects), questions immediately come up.

    "Why don't they get in touch with us, then? Why don't they land right on the White House lawn and declare themselves?" people asked.

In reply, scientists say that, while this may be what we want, it may not necessarily be what they want.

    "The most likely explanation, it seems to me," said Dr. Mead, "is that they are simply watching what we are up to—that responsible society outside our solar system is keeping an eye on us to see that we don't cause a chain reaction that might have unexpected effects for the outside of our solar system."

    Opinions from other scientists might go like this: "Why should they want to get in touch with us? We may feel we're more important than we really are! They may want to observe us only and not interfere(干涉) with the development of our civilization. They may not care if we see them but they also may not care to say 'hello'."

    Some scientists have also suggested that Earth is a kind of zoo or wildlife reserve. Just as we set aside wilderness areas and wildlife reserves to allow animals and growing things to develop naturally while we observe them. So perhaps Earth was set aside ages ago for the same purpose.

    Are we being observed by intelligent beings from other civilizations in the universe? Are they watching our progress in space travel? Do we live in a huge "zoo" observed by our "keepers," but having no communication with them?

    Never before in our history have we had to face ideas bravely like these. The simple fact is that we, who have always regarded ourselves as supreme in the universe, may not be so. Now we have to recognize that, among the stars in the heavens, there may very well be worlds lived by beings who are to us as we are to ants.

When it comes to recycling the household waste, people have done it for about two decades. However, there's still some confusion about what can and what can't be recycled. With advances in technology, there are more things that can be recycled.

COFFEE PODS (咖啡荚)

On average, Australians are using more than three million coffee pods per day, and about 1.5 million households have coffee machines. While the pods are disastrous for the environment, they can still be recycled. Nespresso has a free post-back programme and drop-off points run by TerraCycle, so you can take the pods and directly drop off at Nespresso stores.

LIGHT BULBS

Rather than throwing light bulbs into the bin, some councils run specific recycling stations, which allow you to drop off these kinds of items. If you do regularly recycle household glass, remember all glass should be washed and have lids removed.

PIZZA BOXES

Normally pizza boxes don't make it into recycling because they're covered in grease (油脂) and leftover bits of cheese. When a pizza box is too greasy, it won't be taken to a recycling processing plant. If possible, remove as much of the leftovers as you can before recycling. If the pizza box can't be recycled, tear off the lid which can still be recycled.

HOUSEHOLD BATTERIES

Household batteries can also be recycled. Batteries that do end up in landfills can cause a serious problem to the environment as they can release poisonous chemicals into the soil which are harmful to both humans and animals. Button-cell batteries, which are used in hearing aids and watches, can also be recycled.
