Annie slept in the front of the seat with her father drove through the darkness. ”We're almost there!” Dad announced cheerfully. “Soonwell be observing and counting owls at the state park.” Yawning, Annie nodded and 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 important for 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. The we'll send out a report to a scientific organization that is collecting about birds from people all over the county.”

    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 her coat and tried to keep from trembling. She had not expected the morning to be so frigid. Luckily her gloves were in her pocket.

    Suddenly Annie's father stooped 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 they had seen a screech owl.

    Walking a little farther, they came to a tall oak tree. “This looks 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 all sounded as if the birds were asking, “who cooks for you?” Moments later Annie thought she heard areturn call in distance. She held her breath and waited. Suddenly a huge birdlanded 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 tow feet tall. Gray feathers surrounded its dark eyes. The bird did not matter. Annie would never forge the image of the powerful barred owl.

    After a homeless man offered a college student in England all the money he had so she'd be able to get home safely, the woman is paying it forward—in a massive way.

    The story began in early December. It was about 3 a.m. and Harrison-Bentzen was panic. “I came out after a student night out and realized I didn't have any battery on my phone. I'd lost my friends,” the 22-year-old told BBC Radio 5. She'd also lost her bank card, she discovered, and she had no money.

    Just then, a homeless man, known only as Robbie, approached the young woman and asked her if she needed help. He reached into his pocket and pulled out all the money he had—loose change amounting to about $4.60. He insisted that Harrison-Bentzen take it to pay for a taxi so she'd get home safely.

    Harrison-Bentzen, a student at the University of Central Lancashire in Preston, England, says she refused to take Robbie's money and found another way to get home. But following her encounter（偶然相遇）with the generous man, she says she couldn't get him out of her mind.

    For the next few days, the student searched for Robbie, driving around the streets with her mom and using social media in an attempt to locate the man. In that time, Harrison-Bentzen says she learned more about Robbie and discovered that he actually had a reputation for helping strangers.

    Finally, after four days of driving around Preston, Harrison-Bentzen found Robbie. She was determined to do something to help change Robbie's life.

    So, earlier this month, the student launched a fundraising campaign in Robbie's name. She explained that she would be spending 24 hours on the streets, so as to “understand the difficulties” that the homeless face on a daily basis.

    Harrison-Bentzen says she had initially（最初）hoped to raise about $780 with her campaign. Her expectations, however, were quickly blown out of the water. As of Thursday morning, 4,800 people have donated almost $50,000.

    The days of the hunter are almost over in India. This is partly because there is practically nothing left to kill, and partly because some steps have been taken, mainly by banning tiger-shooting, to protect those animals which still survive.

    Some people say that Man is naturally a hunter. I disagree with this view. Surely our earliest forefathers, who at first possessed no weapons, spent their time digging for roots, and were no doubt themselves often hunted by meat-eating animals.

    I believe the main reason why the modern hunter kills is that he thinks people will admire his courage in overpowering dangerous animals. Of course, there are some who truly believe that the killing is not really the important thing, and that the chief pleasure lies in the joy of the hunt and the beauties of the wild countryside. There are also those for whom hunting in fact offers a chance to prove themselves and risk death by design; these men go out after dangerous animals like tigers, even if they say they only do it to rid the countryside of a threat. I can respect reasons like these, but they are clearly different from the need to strengthen your high opinion of yourself.

    The greatest big-game hunters expressed in their writings something of these finer motives. One of them wrote.

    "You must properly respect what you are after and shoot it cleanly and on the animal's own territory(领地)。You must fix forever in your mind all the wonders of that particular day. This is better than letting him grow a few years older to be attacked and wounded by his own son and eventually eaten, half alive, by other animals, Hunting is not a cruel and senseless killing - not if you respect the thing you kill, not if you kill to enrich your memories, not if you kill to feed your people."

    I can understand such beliefs, and can compare these hunters with those who hunted lions with spears(矛) and bravely caught them by the tail. But this is very different from many tiger-shoots I have seen, in which modern weapons were used. The so-called hunters fired from tall trees or from the backs of trained elephants. Such methods made tigers seem no more dangerous than rabbits.

    Some of the world's biggest companies—Apple, Amazon, Facebook—didn't exist 30 years ago. So what firms are we working for in 2050? That's a question put forward by historian Yuval Noah Harari in his new book "21 Lessons for the 21st Century".

    He argues that because technology is changing so fast, it's one of the first times in human history when we don't know what jobs will look like in the coming three decades." So the best bet is to focus on emotional intelligence（EQ）," he said. "Information is the last thing the kids need. They have too much of it."

    In this book, he focuses on the various challenges facing us today. As he writes in the book's introduction: "What are today's greatest challenges? What should we pay attention to? What should we teach our kids?" One area where these questions crop up is artificial intelligence（AI）Harari believes that AI will completely affect the job market for the next generation of workers.

    His first two books—"Sapiens" and "Homo Deus"—became international bestsellers, selling more than 12 million copies worldwide. They were praised by the likes of Mark Zuckerberg, Barack Obama and Bill Gates. Harari's books, about the past and future of humanity, attract a great number of fans. Fellow Israeli, actress Natalie Portman, is a fan. So is American R&B star Janelle Monae.

    As for Bill Gates, he might be Harari's biggest fan. So when the New York Times asked him to review Harari's latest books, he jumped at the opportunity. "All the three books wrestle with some version of the same question: What will give our lives meaning in the decades and centuries ahead?" Gates wrote in his review. "So far, human history has been driven by a desire to live longer, healthier, happier lives. If science is eventually able to give that dream to most people, and large numbers of people no longer need to work, what reason will we have to get up in the morning?"

    Tiny microbes(微生物)are at the heart of a new agricultural technique to manage harmful greenhouse gas. Scientists have discovered how microbes can be used to turn carbon dioxide into soil­enriching limestone(石灰石), with the help of a type of tree that grows in tropical areas, such as West Africa.

    Researchers have found that when the Iroko tree is grown in dry, acidic soil and treated with a combination of natural fungi(霉菌)and other bacteria, not only does the tree grow well, it also produces the mineral limestone in the soil around its root.

    The Iroko tree makes a mineral by combining Ca from the earth with CO₂ from the atmosphere The bacteria then create the conditions under which this mineral turns into limestone. The discovery offers a new way to lock carbon into the soil, keeping it out of the atmosphere. In addition to storing carbon in the trees leaves and in the form of limestone, the mineral in the soil makes it more suitable for agriculture.

    The discovery could lead to reforestation(重新造林) projects in tropical countries, and help reduce carbon dioxide in the atmosphere in the developing world. It has already been used in West Africa and is being tested in Bolivia, Haiti and India.

    The findings were made in a three­year project involving researchers from the Universities of Edinburgh, Granada, Lausanne and Delft University of Technology. The project examined several microbiological methods of locking CO₂ as limestone, and the Iroko­bacteria way showed best results. Work was funded by the European Commission under the Future&Emerging Technologies(FET)scheme.

    Dr. Bryne Ngwenya of the University of Edinburgh's School of GeoSciences, who led the research, said: "By taking advantage of this natural limestone­producing process, we have a low­tech, safe, readily employed and easily operating way to lock carbon out of the atmosphere, while improving farming conditions in tropical countries."

    The easy way out isn't always easiest. I learned that lesson when I decided to treat Doug, my husband of one month, to a special meal. I glanced through my cook book and chose a menu which included homemade bread. Knowing the bread would take time. I started on it as soon as Doug left for work. As I was not experienced in cooking, I thought if a dozen was good, two dozen would be better, so I doubled everything. As Doug loved oranges, I also opened a can of orange and poured it all into the bowl. Soon there was a sticky dough (生面团）covered with ugly yellowish marks. Realizing I had been defeated, I put the dough in the rubbish bin outside so I wouldn't have to face Doug laughing at my work. I went on preparing the rest of the meal, and, when Doug got home, we sat down to Cornish chicken with rice. He tried to enjoy the meal but seemed disturbed. Twice he got up and went outside, saying he thought he heard a noise. The third time he left, I went to the windows to see what he was doing. Looking out, I saw Doug standing about three feet from the rubbish bin, holding the lid up with a stick and looking into the container. When I came out of the house, he dropped the stick and explained that there was something alive in out rubbish bin. Picking up the stick again, he held the lid up enough for me to see. I felt cold. But I stepped closer and looked harder. Without doubt it was my work. The hot sun had caused the dough to double in size and the fermenting yeast(酵母) made the surface shake and sigh as though it were breathing. I had to admit what the living thing was and why it was there. I don't know who was more embarrassed(尴尬) by the whole thing—Doug or me.
