3 . You have probably read about robots replacing human labour as a new era of automation takes root in one industry after another. However, a new report suggests humans are not the only ones who might lose their jobs.

In New Zealand, farmers are using drones（无人机）to herd and monitor cows and sheep, taking up the position that highly intelligent dogs have held for more than a century. The robots have not replaced the dogs entirely, Radio New Zealand reports, but they have appropriated（盗用）one of the animal's most powerful tools: barking. The DJI Mavic Enterprise, a $ 3,500 drone favored by farmers, has a feature that lets the machine record sounds and play them over a loudspeaker, giving the machine the ability to imitate its canine counterparts.

Corey Lambeth, a shepherd on a farm, told RNZ the machines are surprisingly effective. “That's the one thing I've noticed that when you're moving cows the old cows stand up to the dogs, but with the drones, they've never done that,” he said, noting the drones move cows faster, with less stress, than the dogs do.

The drones come in handy for more than just herding cows and sheep. The robots allow farmers to monitor their land from afar, monitoring water and feed levels and checking on the animals' health without disturbing them. Jason Rentoul told RNZ that a two- hour herding job that used to require two people and two teams of dogs could be accomplished in 45 minutes using a single drone. “On a hilly farm where a lot of stuff is done by farmers on foot, the drones really save a lot of man hours,” he said.

For now, farmers say, there is still a need for herding dogs, primarily because they have a longer lifespan than drones, can work in bad weather and do not require an electrical socket every few hours to recharge.

4 . Festivals and celebrations of all kinds have been held everywhere since ancient times. Most ancient festivals would celebrate the end of cold weather, planting in spring and harvest in autumn .Today's festivals have many origins: some are seasonal, some for special people and some for special events.

Dragon Boat Festival celebrations take place in China on the fifth day of the fifth lunar month. They are held in memory of Qu Yuan, a famous person who wrote poems in Ancient China. It was the first traditional Chinese festival added to UNESCO'S List of Intangible Cultural Heritage.

Thanksgiving is celebrated mainly in North America, in October or November. Traditionally, it was a chance to give thanks for a good year, Now. i is also a time for families to get together for a big dinner.

May Day s a festival to celebrate the start of summer, with celebrations held across Europe and in parts of North America. People prepare decorations with flowers and dance around poles.

The Spring Festival that is also called Chinese New Year is one of the most important Festivals in China.It stars with a new moon and ends 15 day later on the full moon, marking the beginning of spring .During this festival,people eat dumpling, fish and meat and may give children lucky money in red paper. Nowadays, more and more countries around the world are holding celebrations for Chinese Spring Festival.

Festivals let us enjoy life , be proud of our customs and forget our work for a little while.

5 . That the Leaning Tower of Pisa no longer leans quite so much after a ￡20 million project to save it has proved to be a great success.The tower,which was on the edge of collapse,has been straightened by 18 inches,returning it to its 1838 position.

“It has straightened a little bit more than we expected,but very little helps,”said Prof.John Burland,the only British member of the rescue committee.“The tower is still very slightly moving towards being upright.”

The tower,which has been leaning almost since building work first began in 1173,was closed to the public in 1990 because of safety fears.The 183-foot tower was nearly 15 feet off vertical and its structure was found to have been weakened by centuries of strain(作用力).

Prof.Burland said it could have collapsed “at any moment”.However,it took nine years of quarrelling before any work was done.The last attempt at straightening the tower was carried out.Concrete(混凝土) was poured into the foundations,but the result was that the tower sank further into the soil.

The straightening work involved digging out around 70 tonnes of earth from the northern side of the tower,causing it to sink on that side.Before the digging started,the tower was fixed with steel ropes and 600 tonnes of lead weights.

However,halfway through the project,concerns at the ugliness of the lead weights led to their removal and the tower leaned greatly.The weights were hurriedly reattached.One night,the tower moved more than it had averaged in an entire year.The tower’s stonework has also been restored.

The Italian government stepped in after a tower collapsed in Pavia in 1989,killing four people.Experts suddenly realized that the tower at Pisa,which was similarly built and on the same sort of earth,could do the same.

6 . I’ve spent over a year in India,and in those 365 plus days,I’ve learned a lot about getting around Indian cities.My biggest lessons have been learned through being cheated,particularly by taxi and rickshaw(人力车) drivers,but that doesn’t mean those are bad ways to travel,as long as you know what you’re doing.Below are the best ways to get around the city of Delhi,India,and tips for how to keep from being the victim of scams(欺诈).

Taking taxis is a great way to get around the city of Delhi and chances are,if you arrive in Delhi by plane,as soon as you make it through customs,you’ll be swarmed by Indian taxi drivers.At the Delhi airport,be sure to arrange for a taxi to your hotel at one of the two Delhi Traffic Police Taxi Booths.One is inside the airport,and the other is outside.The key is to make sure to go to a booth run by the police,rather than by independent taxi drivers.

Rickshaws are one of my favourite ways to get around Indian cities,in part because it’s how the locals often travel.Auto-rickshaws are more common,but bicycle rickshaws are still used in Old Delhi.If you do have a chance to take a bicycle rickshaw,you should do it at least once for a unique experience that should only set you back about 15 rupees.Auto-rickshaw rates around Delhi range between 30 and 80 rupees,depending on the distance.

If you really want to travel around Delhi like the locals,take a public bus.Indian buses become very crowded and most do not have air conditioning.They are,however,very cheap.A bus trip won’t set you back any more than 15 rupees,as long as you stay within the city limits.Since Indian buses get so crowded,try to board the bus at the start of the route so you can get a seat.

The train is a great way to get around within the city of Delhi.Fares are reasonable,between 6 and 22 rupees.All departure announcements are in both Hindi and English,and tokens can be purchased for between 6 and 22 rupees.

8 . I'd done it before, and so I had no reason to believe that this time would be any different. I was sure that when I returned home from my mission trip, as always, I'd bring back nothing more than some mud on my boots, a hole or two in my jeans and, of course, a lot of great memories.

The summer before my high school graduation, I went to West Virginia with others as volunteers to repair the homes of those in need. Arriving at our destination, my group was assigned the task of rebuilding sections of a home that had been damaged by fire. No sooner had we parked on the home's dirt driveway than we saw an excited little girl, no more than six years old, standing in the doorway of the family's temporary home. Shoeless and wearing dirty clothes and the biggest smile I'd ever seen, she yelled, "Ma, Ma, they really came! " I didn't know it then, but her name was Dakota, and four more days would pass before she’d say another word near me.

Behind Dakota was a woman in a wheelchair—her grandmother, we'd soon learn. I also discovered that my job that week would be to help change a fire—damaged dining room into a bedroom for this little girl. Grabbing our tools, we went to work. Over the following days, I noticed Dakota peeking at us every now and then as we worked. A few times. I tried talking with her, but she remained shy and distant, always flying around us like a tiny butterfly but keeping to herself.

By our fifth and final day, however, this was about to change.

Before I went to work on her home on that last morning, I spoke for a moment or two with the grandmother. I was especially pleased when she told me how much Dakota loved her new room so much, in fact, that she'd begged to sleep in it the previous night, even though it wasn't quite ready. As we talked, I noticed something I hadn’t seen before—Dakota was hiding behind her grandmother. Cautiously, she stepped into view, and I could see that just like her clothes, her face was still dirty. But no amount of soil could hide those bright blue eyes and big smile. She was simply adorable. I wanted so much to hug her, but respecting her shyness, I kept my distance.

Slowly, she began walking toward me. It wasn't until she was just inches away that I noticed the folded piece of paper in her tiny hand. Silently, she reached up and handed it to me. Once unfolded, I looked at the drawing she'd made with her broken crayons on the back of an old coloring book cover. It was of two girls—one much taller than the other—and they were holding hands. She told me it was supposed to be me and her and on the bottom of the paper were three little words that instantly broke my heart. Now almost in tears, I couldn't control myself anymore—I bent down and hugged her. She hugged me, too. And for the longest time, neither one of us could let go.

By early afternoon, we finished Dakota's bedroom, and so I gladly used the rare free time to get to know my newest friend. Sitting under a tree away from the others, we shared a few apples while she told me about her life. As I listened to her stories about the struggles she and her family went through daily, I began to realize how boring various aspects of my own life were.

I left for home early the next morning. I was returning with muddy boots and holes in my jeans. But because of Dakota, I brought back something else, too—a greater appreciation for all of the blessing of my life. I’ll never forget that barefoot little butterfly with the big smile and dirty face. I pray that she’ll never forget me either.

Stillness not only slows the pace of life, but also ________ the soul, helping us to enjoy the world’s small pleasures and realize the truth of life.

10 . People think of cats as cute. But research published in a psychology journal calls them neurotic (神经质的) and unstable. Researchers from the University of Edinburgh in Scotland and the Bronx Zoo in New York compared the personalities of domestic house cats with those of four different types of wildcats.

To better understand their personalities, the researchers rated a number of animals behaviors on what psychologists call the Big Five human personality traits (特征).

Domestic house cats have similar personality structures to African lions. “It’s what cats do pretty much on a daily basis, things like being anxious, being timid, being excitable, being aggressive toward humans, being aggressive toward each other, ”said Max Wachtel, a Denver psychologist who didn’t participate in the study. “All of those are characteristics you see in those cute little house cats, and you also see them in lions.”

If you ever thought your cat was anxious, insecure, tense, suspicious or aggressive toward you, you aren’t making it up, he said. If they were bigger, they probably would consider killing you.

But the news isn’t all bad: Just like lions, house cats are also playful, excitable and impulsively funny. They just aren’t very predictable. One moment cats will be enjoying bell scratches, and the next they will be biting you to make you stop.

“It is good to understand the personality characteristics of our pets,” Wachtel said “Different cats have different personalities, but as a species, there are a lot of commonalities.”

The researchers also studied personality traits of Scottish wildcats and some other animals “Across the five species we assessed, personality structure was strikingly similar and also seemed to be related to other studies’ findings, such as in tigers,” the researchers wrote in their study in the November 2014 issue of the Journal of Comparative Psychology. But house cats were most like lions, potentially because they live in semi-social surroundings and lions are the most social of cats.

“They’re cute and furry, but we need to remember when we have cats as pets, we are inviting little predators into our house,” Wachtel said. “Cats can be fantastic, sweet companions—until they turn on you.”
