It is reported that conservation groups in North America have been arguing about the benefits and dangers of wolves. Some groups believe wolves should be killed. Other people believe wolves must be protected so that they will not disappear from the wilderness(荒野).

For Killing Wolves

    In Alaska，the wolf almost disappeared a few years ago，because hunters were killing hundreds of them for sport. However, 1aws were established to protect the wolves from sportsmen and people who catch the animals for their fur．So the wolf population has greatly increased. Now there are so many wolves that they are destroying their own food supply.

    A wolf naturally eats animals in the deer family. People in the wilderness also hunt deer for food. Many of the animals have been destroyed by the very cold winters recently and by changes in the wilderness plant life．When the deer can't find enough food，they die.

    If the wolves continue to kill large numbers of deer, their prey(猎物) will disappear some day. And the wolves will, too. So we must change the cycle of life in the wilderness to balance the ecology. If we killed more wolves, we would save them and their prey from dying out. We'd also save some farm animals.

    In another northern state, wolves attack cows and chickens for food. Farmers want the government to send biologists to study the problem. They believe it necessary to kill wolves in some areas and to protect them in places where there is a small wolf population．

Against Killing Wolves

    If you had lived long ago，you would have heard many different stories about the dangerous wolf．According to most stories，hungry wolves often kill people for food．Even today，the stories of the “big bad wolf” will not disappear．

    But the fact is wolves are afraid of people, and they seldom travel in areas where there is a human smell．When wolves eat other animals，they usually kill the very young, or the sick and injured. The strongest survive. No kind of animal would have survived through the centuries if the weak members had lived. And has always been a law of nature.

    Although some people say it is good sense to kill wolves，we say it is nonsense! Researchers have found wolves and their prey living in balance．The wolves keep the deer population from becoming too large, and that keeps a balance in the wilderness plant life.

    The real problem is that the areas where wolves can live are being used by people. Even if wilderness land is not used directly for human needs, the wolves can't always find enough food. So they travel to the nearest source, which is often a farm. Then there is danger. The “big bad wolf” has arrived! And everyone knows what happens next.

    Helen Thayer, one of the greatest explorers of the 20th century, loves challenges. She says, “I like to see what's on the other side of the hill.” She has gone almost everywhere to do that.

    In 1988, at the age of 50, she became the first woman to travel alone to the North Pole. She pulled her own sled (雪橇) piled with 160 pounds of supplies, and during her trip no one brought her fresh supplies. Accompanied (陪伴) only by her dog Charlie, she survived cold weather and meetings with polar bears. In fact, Charlie saved her life when one of them attacked her. Near the end of her trip, a forceful wind blew away the majority of her supplies. The last week of the trip, she survived on a handful of nuts and a little water each day.

    Helen goes to challenging places not only for adventure, but also for education. Before her Arctic journey, she started a website called Adventure Classroom. On the site, she shares her adventures in order to motivate (激发) students. She explains, “Although kids often see the world in a negative way, without hope for their future, we work to inspire them to set goals, plan for success and never give up…” Helen grew up in New Zealand. Her parents were athletes and mountain climbers. Following how parents' example, she climbed her first mountain at 9. Later, she climbed the highest mountains in North and South America, the former USSR and New Zealand.

    In 1996, she took on another challenge-the Sahara Desert. She and her husband, Bill, walked 2,400 miles across it! In 2001, she and Bill traveled on foot from west to east through the Gobi Desert in Mongolia. They hope to travel in mainland China into Sichuan and Tibet to study pandas this year.

    Helen plans to continue taking trips. She'll use her colorations, writing, photography and environmental work to create programs for her Adventure Classroom website. She wants to inspire her students never to stop facing challenges!

    For the business traveler who is all about efficiency: Check out these hotels that will get you in and out with a minimum of trouble. When you are pressed for time on a business trip, nothing can infuriate you more than a slow hotel check-in process. On your next trip, try these hotels that offer a speedier check-in process.

⒈Yotel New York

    The self-service kiosks at this high-tech New York hotel work just like the ones you'd see at an airport. There are just five-steps to register and obtain your card key. There is even a robotic luggage bellboy. You tap in the number of bags you are carrying and sizes, then wait for a robot arm to swing down and store your luggage in a locker (say, for a day trip). This also speeds up the check-in process if the first thing you need to do, like me, is head to a series of meetings.

⒉Marriott Detroit Airport

    Another option for business travelers in a hurry: Marriott is rolling out its mobile check-in app to 325 hotels this year, including the Marriott Detroit Airport hotel. (I've tested the app itself but not for a real visit quite yet.) Here is the basic idea: you download the iphone or Android app. The night before, you can “check-in” virtually. When you arrive, you get an alert that the room is ready and your key, which is already tied to your reservation, is waiting for you at the desk.

⒊Hyatt Regency Minneapolis

    I happened to stay at this hotel recently and liked how fast the kiosk check-in works. Like the Yotel, the kiosk asks you to insert your credit card, similar to an airport terminal. The whole process took about three minutes, when I left, I was equally impressed with the fast check-out. An agent meets you in the lobby with an ipad and asks for an email to use for a receipt. The big advantage: you never have to wait in line.

⒋Radisson: LaCrosse

    The Radisson is trying to make the kiosk process even faster, at a few select hotels like the Radisson Lacrosse in Wisconsin, you use a mobile app to register and then receive a barcode by email or text. When you get to the kiosk, you scan the barcode to get your key without any other steps required. It's super fast. You can find this new check-in system at the Radisson hotels in Salt Lake City, Seattle, and Phoenix as well.

    In the tenth grade, I began working for free at a vet's that was run by a friend. I wanted to get experience for what I thought would be my future job. However，on one particular Saturday morning I learnt something perhaps more important.

    The hospital was in the middle of one of the poorer sections of the city and some people could only pay for the most basic treatments. On this Saturday，a man and his young son，who was probably about 7 years old，walked in with a small cat in a cardboard box. There was something wrong with the cat's left eye. But the man could not afford to pay for the cost of the medicine. He kept quiet for a while，and then he asked where the nearest animal shelter was. Hearing this，his son cried and started to argue with him. All of a sudden，an older woman who was sitting in the waiting room stood up，walked up to the counter，and told the man that she would pay for the cost. The man thanked her and the son got to keep a healthy cat.

    I always thought it was the right thing to help out a needy person，but I only saw people do acts of kindness on TV or in movies. What the woman did made me believe that these things do happen in real life，and quite often.

    Now，when I can't decide whether to help someone who is in need，I remember this woman，and then I have the courage to step up to the plate. Sometimes other people follow.

    LOS ANGELES — Kobe Bryant is a winner in retirement, too. The former Los Angeles Lakers star won an Oscar in the animated short category for "Dear Basketball," a poem he wrote after ending his 20-year career on the court in 2016.

    He'll add it to an already jammed trophy collection that includes five NBA championships with the Lakers, two Olympic gold medals, NBA Finals most valuable player awards, a league MVP award and four All-Star game MVP awards.

    As executive producer, Bryant accepted his golden Oscar statue from "Star Wars" star Mark Hamill on Sunday night. He shared the award with Disney animator Glen Keane.

    Among those offering their congratulations via Twitter were Hall of Famers Magic Johnson, Bill Russell and Shaquille O'Neal, Bryant's former Lakers teammate who admitted, "I'm jealous!"

Since hanging up his basketball shoes, Bryant has thrown himself into business (a new Nike shoe) and various forms of storytelling.

    "As basketball players, we're told to shut up and dribble," Bryant said on stage. "I'm glad we did a little bit more than that."

    He thanked his wife, Vanessa, and his three daughters, naming each of them. He spoke a few words of Italian — a language he learned as a child growing up in Italy — and closed by telling them, "You are my inspiration."

    Long before iPhone, the cigarette was the companion of choice for restlessness. And long before Facebook and WeChat, it was tobacco that promised to better your social life. Now, quitting smartphones has become the new quitting smoking.

    Of course, technology does not yellow your teeth, cause disease or lead to cancer. But some individuals are so concerned that device addiction is damaging their mental health. In order to reduce their dependence, even in Silicon Valley, people are turning off the messages that constantly buzz for their attention, banning smartphones from the bedroom and, curiously, changing the colors on their screens to a less tempting scale of gray.

    The big tech companies will have to work out how to respond to this new generation of quitters. Facebook is the first to go public with its attempt, hoping its recent move can make the social network more homely.

Last year the tech industry got a bad name —Big Tech—with unfortunate echoes of other industries that have faced fierce opposition, including Big Tobacco. Like them, the tech industry has to reduce concern from a new generation of activist shareholders （股东） that are questioning its role in the world. These campaigns are never as fierce as those faced by Big Tobacco. In the 1990s, socially responsible investors refused to put money in tobacco stocks.

    It is far difficult for investors to challenge Big Tech and hard to separate the good these companies do in the world-connecting old friends and giving space for people to share their ideas-from the bad. In the meantime, stopping using technology remains problematic. In The World Without Mind: The Existential Threat of Big Tech, Franklin Foer argues that tech should be seen in a similar way to junk food: a convenience that some reject for more continuing nutrition.

    So we need to do more to turn the tide. In the same way that public service announcements made smoking around your children taboo （禁忌）, we can warn parents against losing themselves in their smartphones while taking care of kids. We can also create no-smartphone zones at dinner. Eventually smartphones could be banned from all public places and help us give our attention to the people around us instead.
