Should you work out in the gym in the morning instead of in the evening? It all depends. Of course, there are advantages of working out(运动) in the morning.

    You will increase your energy for the rest of the day. “Morning workouts result in better energy levels throughout the day and give you more mental sharpness,” says Dr. Cedrie Byrant, Chief Science Officer of the American Council on Exercise.

    Here is another advantage. In 2017, health researchers found that exercising in the morning helps you sleep better at night. According to the study, in all cases, those who exercised at 7:00am experienced about a 10 percent drop in blood pressure that carried through the rest of the day. They also had about a 25 percent drop in blood pressure at night, slept longer and had more beneficial sleep cycles than when they exercised at other times of the day.

    However, there are disadvantages, too.

    If you are not an early riser, getting out of the bed in the morning can be very difficult. Byran says that if you're not used to exercising in the morning and force yourself to get up, you may not put as much effort into the exercise as you would later in the day. Also, if you aren't careful, you can damage your sleep schedule, which can lead to insufficient sleep.

    Besides, hitting the gym before work can cause a challenge in terms of scheduling. If you work a 9-to-5 job, getting ready for work and going to work can cut your morning workout short, Byrant notes.

    To sum up, it has both advantages and disadvantages. If it suits you better to work out in the morning, you can do so.

    Today, I felt upset, I decided to take a walk even though I didn't know where I would go. The most extraordinary thing happened when I was out on this walk. I saw an old man sitting on a chair. He was a seller of second-hand shoes. He seemed so tired and nobody was buying his shoes.

    I wanted to give him something but I had not brought anything with me. Then, a little girl came toward him. I heard the child say, ''Grandfather, may I polish your shoes?" That old man took pity on her, smiled and he gave her a shoe to polish. The girl said, I polish the shoe because I need money to buy my brother a new school uniform. The old man answered, "Oh, little girl. Just stop doing this. Come with me and I will buy you a uniform.”

    Then they walked to a market (I followed behind) and he bought her a uniform. The girl was so happy. She said, Thank you so much for doing this." Then she left, leaving the old man smiling. He walked away from the market, but I stopped him.

    I whispered in his ear, "You are a hero! Thank you for your kindness!” As I walked away, I glanced back and I could see him still smiling. I was blown away by the kindness I had just seen. Someone who had so little himself was able to show such incredible generosity! Amazing!

    My own sadness had completely disappeared, chased away by the light of this kind act. I began realizing that I have a lot to be thankful for.

    This past summer I went on a journey to Canada's Arctic with Students On Ice. When I left Calgary I wondered what I would find what I would learn and who I would meet. On the trip to Ottawa I was wrapped in a blanket of uncertainty and excitement. But when I first met the group of students, scientists and leaders, I knew that l didn't have anything to worry about. The group was amazingly receptive and I was soon part of a big family setting out on an amazing adventure—an adventure of a lifetime!

    When we reached the Arctic I saw a vast Land that appeared untouched and original. I was surprised by its great size and beauty and my senses were repeatedly shocked and amazed. I stood on the Kapitan Khlebnikov and saw twelve polar bears. They walked in search of seal holes, and patiently waited for a meal. I learned that polar bears are successful only one out of every twenty hunting attempts.

    However, I learned that the Arctic and its people are being threatened by pollution and global warming. I learned that pollutants are carried by ocean and air and have a bad effect on all Arctic people. I learned that global warming has put polar bears at risk because a warmer climate means that they have a shorter time to hunt seals on the ice.

    The trip was a feast (盛宴) for the senses. I have learned more about our environment, and particularly how alive and interesting the Arctic is and why it is so important to take care of it. I learned pollution, ignorance of individual and global problems need to be solved. The Arctic deserves to be preserved. My trip with Students On Ice has made me more determined to try to ensure that I do not leave harmful footprints on either Earth or its people.

    While every dog owner knows their dogs can read their moods perfectly, scientists have always been a little doubtful. Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria, we finally have some convincing evidence.

    For their study, biologist Corson Miller and his team exposes eleven selected dogs to digital images of women that were either angry or happy. Half the dogs were rewarded for touching the screen when shown a happy face, while the other half got their treat for selecting those that appeared angry.

    Interestingly, the dogs were not provided with the entire face. Some dogs were shown only upper halves while the others observed lower halves. That's because the scientists believe humans show their emotions on their entire face.

    After some training like how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face. The researchers concluded the dogs were smart enough to read human emotions.

    They also found those being trained to read angry expressions took a longer time to learn. They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly. However, once the smart dogs realized they were getting rewarded, the trepidation seemed to disappear. In fact, the dogs had such a good time playing the computer "game" That scientists had a hard time keeping them away from the touch screens after the study was completed.

    The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly. Since the touch-screen models were all females, this confirmed what has been observed in previous studies dogs are more efficient at reading facial expressions of people that are the same gender as their owner.

    According to the International Ecotourism Society, eco-travel is "responsible travel to natural areas that protects the environment, maintains the well-beings and involves education". Eco-travel is on the rise, as more and more people become conscious about their carbon footprint.

    Expert from Boundless Journeys, Matt Holmes, who works-on travel experiences towards conserving areas said, "As scientists and non-scientists learn more about how we human beings are impacting the planet, I think more people want to do what they can while still exploring the world. Our guests are definitely interested in that aspect of our journeys. Travelers can farm their own food in Italy, managing their use of water and using solar or wind power. They can also visit n family-run camp that cares for retired logging elephants in Myanmar, know a park entry fee goes to a conservation organization in Costa Rica, employ and train members of the local community or partner with a protection group. There are lots of options for seeking out greener holiday."

    Most people believe that eco-travel is expensive and it is true. Matt explained "Anti-poaching patrols (巡逻) need to be paid, solar energy equipment costs a lot to install, building with environmentally friendly, materials is more expensive and so on. The extra cost is necessary, as you're paying to minimize your footprint and protect the places you visit, which is exactly what eco-travel is about. The financial success and sustainability (可持续性) of an eco- focused operation doesn't come from thin air." The industry is trying to make eco-travel affordable and make it accessible to the common people.
