Do you love holidays but hate the increase weight that follows? You are not alone. Holidays are happy days with pleasure and delicious foods. Many people, however, are worried about the weight that comes along with these delicious foods.

    With proper planning, though, it is possible to control your weight. The idea is to enjoy the holidays but not to eat too much. You don't have to turn away from the foods that you enjoy. The following suggestions may be of some help to you.

    Do not miss meals. Before yon leave home for a feast(宴会),have a small, low-fat snack(小吃). This may help to keep you from getting too excited before delicious foods. Begin with clear soup and fruit or vegetables. A large glass of water before you eat may help you feel full. Use a small plate; a large plate will encourage you to have more than enough. Better not have high-fat foods. Dishes that look oily or creamy have much fat in them. Choose lean meat(瘦肉 ).Fill your plate with salad and green vegetables. If you have a sweet tooth, try mints (薄荷) and fruits. They don't have fat content as cream and chocolate.

    Don't let exercise take a break during the holidays. A 20-minute walk after a meal can help burn off excess(过多的) calories.

    I want to tell you the story of one of my old friends called Bob，His teachers called him A Troublemaker，They also said that he had no future and no hope. But now he owns a small second -hand bookstore store which makes him enough money to live on and also to support his mother.

    He told me that after he finished grade nine, he went to study at a technical college. He was a pretty bad student so he became one of the gang (一帮) leaders there. Many of them got caught many times for fighting.

    It looked like nothing could change his life. That was until one sad day when his father died. That changed everything.

    After his father died, his mother had to work very hard to make enough money to support the family. He told me that he really pitied his mum after his dad died. He felt that he needed to earn some money rather than let his mum work alone. He loved reading cartoon(卡通)books and had been collecting them for years. As his family was short of money, he decided that he should sell them. He did this by the side of the road where his mother was selling food.

    Soon he realized that his books were very popular. So he decided to set up his own business. He started his business by going around buying cartoon books from other people. He bought them for 25% and then sold them for half price. He could make enough money to help support the family.

    He was a troublemaker to his teachers but he is a hero to me. If you are judged as a bad student or as someone being stupid, I suggest you pay no attention to what they say. Just do your best in everything. Don't give up so easily. Believe in yourself. If you think that you can do it, then you can. Believe me, one day you could be more successful than those persons who looked down upon you.

    For thousands of years, people thought of glass as something beautiful to look at. Only in large glass windows. Glass bottles and jars that hold food and drink allow us to see the contents. Glass is used to make eyeglasses, microscopes, telescopes, and many other extremely useful and necessary things.

    Until the Second World War, most of the glass used for optical (光学的) instruments was imported from Europe. However, during the war Americans could not get European glass, and they were forced to make their own. Therefore, new kinds of glass were developed that had been previously unknown. These new effects were achieved by mixing other chemical elements with the sand. Some of the new glass is very strong and can resist many kinds of shocks. Legend (传说) has it that a kind of very hard glass was invented by a Roman who showed his discovery to the Emperor. When the Emperor saw the glass he feared that it would become more valuable than gold and sliver, making his treasure worthless. Therefore, he had the glass-maker killed, and the secret was not discovered again for hundreds of years.

    In the present century, safety glass was invented for use in modem cars and planes. Safety glass is made by placing a layer of plastic between two layers of plate glass. When the outside layer of glass is broken, the pieces do not scatter (散开) and injure people. Some glass of the type is strong enough to resist bullets (子弹).

    Although nowadays plastics have replaced glass under conditions where glass might be easily broken, there are new uses being developed, for the greatest advantage of glass is that its component (组成的) parts are inexpensive and can be found all over the world.

    Mandara seemed to know something big was about to happen. So she let out a yell, caught hold of her 2-year-old daughter Kibibi and climbed up into a tree. She lives at the National Zoo in Washington D. C.

    And on Tuesday, August 23rd, witnesses said she seemed to sense the big earthquake that shook much of the East Coast before any humans knew what was going on. And she's not the only one. In the moments before the quake, an orangutan（猩猩）let out a loud call and then climbed to the top of her shelter.

    “It's very different from their normal call,” said Brandie Smith, the zookeeper. “The lemurs（monkeylike animals of Madagascar）will sound an alarm if they see or hear something highly unusual.”

    But you can't see or hear an earthquake 15 minutes before it happens, can you? Maybe you can—if you're an animal. “Animals can hear above and below our range of hearing,” said Brandie Smith. “That's part of their special abilities. They're more sensitive to the environment, which is how they survive.”

    Primates weren't the only animals that seemed to sense the quake before it happened. One of the elephants made a warning sound. And a huge lizard（蜥蜴）ran quickly for cover. The flamingoes（a kind of birds）gathered before the quake and stayed together until the shaking stopped.

    So what kind of vibrations（震动）were the animals picking up in the moments before the quake? Scientist Susan Hough said earthquakes produce two types of waves—a weak “P” wave and then a much stronger “S” wave. The “P” stands for “primary”. And the “S” stands for “secondary”. She thinks the “P” wave might be what sets the animals off.

    Not all the animals behaved unusually before the quake. For example, Smith said the zoo's giant pandas didn't jump up until the shaking actually began. But many of the other animals seemed to know something was coming before it happened. “I'm not surprised at all,” Smith said.

    When young, I loved going on trail(小路) runs. It was my favorite way to escape stress. So, when I was back in my hometown after a tough first year of my Ph. D. program, I thought a trail run was just what I needed. But instead of helping me relax, the run did just the opposite.

    After I moved to the city for college, where my runs were on flat concrete paths instead of winding dirt trails, I used a GPS watch. When I went on trail runs again in the country, it constantly reminded me of the fact that I wasn't keeping up with my usual pace. I turned my watch off, thinking that would allow me to enjoy my surroundings and find the peace I expected, but I worried I was underperforming. "Why can't I let go and just enjoy myself?" I wondered. But after some introspection(反省), I realized why I was struggling­both on trail runs and in graduate school.

    Going into my Ph. D. , I had thought that my solid undergraduate track record would set me up for instant success. To my surprise, I was wrong. I lacked confidence in my research abilities which I thought stopped me performing well and I constantly felt my progress was too slow. Other students'self-confidence and their excellent results made me feel insecure. Finally, one day I broke down in tears in my adviser's office.

    Then came my visit home: I was having trouble because I hadn't properly adjusted my expectations to the differences between an urban run and a trail run.

    A Ph. D. is like a trail run: Sometimes you can run fast. Sometimes you might find yourself climbing up a steep, winding trail at a snail's pace. And that's OK. Barriers are unavoidable, and success looks and feels different on a challenging trail than it does on a smooth, flat path. Sometimes it's best to take a deep breath and do your best to meet the challenge.

After a long and hard journey that made international headlines, China's famous herd of wandering elephants appears to finally be heading home.

In August, the 14 Asian elephants of various sizes and ages were guided across the Yuanjiang river in Yunnan and a path was being made for them to return to the nature reserve in the Xishuangbanna Dai Autonomous Prefecture.

The elephants' return completes a more than 500km odyssey that caught the attention of the country. The highlights of their trip included the birth of a calf in Pu'er in last November; and going viral for taking a nap. If they were just taking a walk in the forest, it wasn't a big deal. But the fact is, they left whatever they stepped on in ruins, causing great damage to local residents.

Local wildlife experts have been unable to pinpoint the reason the herd decided to move. One reason is given that the population of elephants in the nature reserve in the Xishuangbanna Dai Autonomous Prefecture is so large, which has increased from 190 to over 300 since 40 years ago, that there is not enough food for them. Some say that their move is due to the influence of the magnetic field of the earth and there is another story saying maybe that lead elephant lost its way, thus leading the herd out of the way. But Zhang Li, a professor on conservation biology at Beijing Normal University, told the Global Times in June that large-scale human engineering developments have sped up the ‘islanding'of elephant habitats.

This meant "the traditional safe zones between humans and elephants are gradually disappearing, and the chances of elephants encountering humans naturally increase greatly".
