In the middle of the 20th century people were worried about whales.The number of whales killed worldwide came up to 66,000 per year.However,people weren't worried about the whale as an endangered animal.Instead,they were worried about the whale industry,which would disappear if there were no whales.In 1946,the International Whaling Commission was established.It limited the whale hunting for every country and controlled the whale industry.But the commission recognized that the limitation wasn't enough.They set a worldwide law against hunting whales with only two exceptions: the hunt for scientific research and "aboriginal whaling".Aboriginal whaling allows some countries to hunt a limited number of whales because it is a part of their culture.Some countries like Japan and Norway don't care about the law;they make excuses to hunt whales and sell the products.They only care about the money.

    Many fishermen complain that dolphins,also a kind of whale,steal their fish.Therefore,they kill thousands of them.In fact,this is not the truth.In reality there are so many fishermen who steal the fish from each other.Some whale hunters say that they catch the animals for scientists.They have to research what whales are eating.For that, they kill them and look into their stomach.The truth is that they only want to sell the meat.Today scientists want to observe live whales for their research.

    Many whale families are not protected and thousands of them are killed.Nobody knows if all whale families would survive,even if humans end all whale hunting today.The pollution of the oceans increases fast and the poison gets into the bodies of the animals.Many of them get sick and die.The human being has killed 90%-95% of many whale families.Others are already extinct.

    Today some international organizations try to protect whales.They make reports to explain how important and endangered whales are.Now people are becoming more interested in whales and a complete new industry has developed,whale watching,which you may want to learn about.

    Have you ever felt like you are not given the kind of respect you deserve? In one way or another, all of us have felt this way. We've yearned(渴望) to be looked at as an authority, someone people look up to and trust. We're not taught in school how to do this and our parents didn't tell us the secret on how to establish our authority. It's something we learn and gain by ourselves. And the answer is as simple as changing our mindset. What? No way! Oh but it is. People tend to underestimate the power of the mind. Change your game by changing your mind.

    Take time to look back and think about people in your life who are an authority or a leader at work, who has more credibility(可信度) than you or who you look up to and inspires you. They are up there not for the reasons you think. If you really think about it, they aren't the smartest of the bunch, not the most educated, and neither are they the best. And in no way do they even call themselves an expert. Instead, they are up there because they are great teachers and advocates(支持者) for the success of their customers or employees.

    Let's take Richard Simmons for example. This famous fitness personality has been a household name ever since he started gaining popularity during the first few years of his career. Stop and think, though, do you really think he is the best person to really get people into shape? Is he the Einstein of fitness and nutrition? Or does he even call himself a master of his craft? Of course not. People look up to him and give him authority because he is a great educator. Instead of sharing information that's far too complicated to understand, he figures out what your problems are and finds out a way to fix them. He even has social media that he updates on a regular basis with topics that are helpful and easy to understand for his fans and followers.

    Depending on the field you're in, you can share with people things you know and that you think they will want to know as well. If you're a nurse, for example, you can make a blog post for common health problems and quick remedies(治疗方法) people can do at home. Remember, the simpler you can make it, the better. People will trust you completely if you give them easy solutions. Like Richard, you'll soon be the expert you'll want to listen to. You can be an advocate also by showing people that you have their best interests at heart. You can also start up conferences to take up people's concerns and try to deal with them the best way that you can.

    So, how will you be viewed as an authority? Make that mind shift. Find out what concerns and troubles your target. Give solutions. Show that you care. And help them climb up that ladder of success. Ladies and gentlemen, that's how it's done.

    Today, I had the good fortune to join the students from East Silver Spring Elementary School in Maryland as they walked and biked to school in celebration of International Walk to School Day. I want to thank Principal Morrow and the entire ESS community for welcoming me so enthusiastically.

    Walk to School Day is a great opportunity for me to spend time with parents, kids, and teachers and to present our Safe Routes to School program and the First Lady Michelle Obama's Let's Move initiative（倡议）.

    As a father, grandfather and former schoolteacher, I know how important it is that we provide students with safe choice to get to school while promoting exercise and healthy lifestyles. That's why I've embraced the Safe Routes to School program so wholeheartedly since I became Secretary of Transportation.

    You know, we're looking at an increasingly sedentary（久坐的）generation of children. One out of every three kids in America is now overweight. And I admire the First Lady's effort to end this within a generation. Safe Routes to School is a natural partner for Let's Move. For more than 10 years, Safe Routes to School has been making it easier for students to walk and bike from home to school. And ESS, where I walked today, is one of the earliest schools to participate.

    We know this program has been enormously effective because of the steady increase in the number of kids walking or biking to school. And as we made our way down the street this morning I was reminded yet again of this program's extraordinary work.

    Look, walking and biking to school is good for students' health. It's good for the environment. And it's good for the entire community's quality of life.

Everybody wins when kids take Safe Routes to School.

    A man came home from work late, tired, to find his 5-year-old son waiting for him at the door.

    “Daddy, how much money do you make each hour?”

    “If you must know, I make ＄20 each hour.”

    “Oh,” the little boy answered, with his head down. He thought for a moment, looked up and said, “Daddy, could you lend me ＄10?”

    The father was furious, “If you asked for the money to buy a toy or some other rubbish, go straight to your room and think about why you are so selfish (自私)！”

    The little boy went to his room with no words and shut the door. After a short while, the father calmed (平静) down, and started to think, “Maybe he really needs to buy something and he didn't really ask for money very often.” So he went to the little boy's room.

    “Sorry！Maybe I was too hard on your just now.” said the man, “Here's ＄10.”

    “Oh, thank you Daddy！” he said happily. Then the boy took out some coins. When the father found that the boy already had money, he got angry again.

    “Why do you want more money since you already have some?” the father shouted angrily.

    “Because I didn't have enough, but now I do.” The little boy replied, “Daddy, I have ＄20 now. Can I buy one hour of your time? Please come home early tomorrow. I would like to have dinner with you. ”

    Families around the country are finding new options for their children's midday meal thanks to a growing number of delivery options catering to students. Kiddos Catering in Chicago adopts a method of providing restaurant meals to schools that contract with it. Owner Michelle Moses and her staff work with area restaurants to create a variety of kid-friendly choices and deliver the meals to the schools five days a week. Parents select the lunches from an online order form that lists the day's featured restaurant and its menu choices.

    "Each day is a different restaurant with six to 10 menu options," she said. "It offers so much choice to kids." The service appeals to parents because they think their children are less likely to toss out restaurant food than a packed lunch, Ms. Moses said. The schools appreciate that Moses handles the ordering, payment, pickup, and food distribution in the cafeteria. "Schools really want to be in the business of educating kids," she said. "They don't want to be in the food and beverage(餐饮) business."

    That doesn't mean that schools always like it when teens (or parents) take it upon themselves to order food through phone apps. Many schools have banned that practice, citing safety concerns about delivery drivers showing up at school unannounced and the burden of tracking down students to alarm them that their meals have arrived.

    "These types of deliveries pose an unnecessary security risk for students and staff," said Bernard Watson, director of community relations for Gwinnett County Public Schools in Suwanee, Ga. "In addition, our award-winning school nutrition program provides students with a wide variety of tasty, nutritious meals on-site, so there is no need to order food from outside."

    Jacob Levin, a recent graduate of Bexley High School in Bexley, Ohio, relied on a sub shop to deliver a sandwich to him during lunchtime meetings or other appointments that conflicted with his lunch period. "It was a convenient option. In most cases, I would not have been able to eat at school if it weren't for the delivery option," he said. "Having a restaurant-quality sub also was much more enjoyable than cafeteria food."

Last September an American started a trip through Southwest China on a standard bike she had bought at a local shop. In three months, Jennifer Holstein cycled 2,500 kilometers through three provinces with just two small bags.

Living in Beijing, her life was already great. But Holstein felt the urge to travel the world and look for adventure. It was mid-August of 2021 that the idea came to her to travel China by bicycle. At that time, Holstein had never cycled for more than 20 kilometers around her local city of Beijing.

Holstein shared an experience from the beginning of her trip when she found herself stuck in a tunnel (隧道) with a flat tire (轮胎). It was dark and hot, and she was so scared because she had never changed a tire before. Suddenly, a group of cyclists old enough to be her grandparents came and rescued her.

In addition to receiving the kindness of people across China, Holstein also experienced several unique cultural experiences by attending three local weddings. She spoke about one wedding in detail, "I was in the middle of a small village in Sichuan province, and I was taken into a local Tibetan family's home and they invited me to take part in a wedding. They gave me a dress and even did my makeup. I never thought I would ever have the chance to take part in a Tibetan wedding."

According to Holstein, "Many people want to travel the world and take huge risks, but never do. Don't just live your life hoping your wildest dreams will become a reality someday. Try first and the rest will work itself out." In addition to biking for her own passion and curiosity, Holstein also linked her ride to raise 22,000 yuan for the United Foundation for China's Health.
