A big bowl of milk can be a great way to start the day. Many snack bars contain nutrients that help our bodies stay strong and healthy. But some of these foods are packed with too many vitamins and minerals. According to a new study by the Environmental Working Group (EWG), this extra fortification may be more harmful than helpful.

    Of the tested snack bars, 27 have more than 50% of the recommended amounts of vitamin A, niacin and zinc. Nutrition facts listed on packages are based on recommended daily values for adults, who are physically larger and require more vitamins and minerals. So when kids eat these cereals (麦片) and snack bars, they are getting more nutrients than they need.

    Vitamin A, niacin (烟酸) and zinc (锌) are best in fresh and unprocessed foods that are in their natural state. Vitamin A helps you see at night. It occurs naturally in eggs, meat and carrots. Niacin is a vitamin that helps our bodies make energy. It is found in foods like fish, seeds, and peanuts, as well as in whole grains like wheat and brown rice. Zinc helps our bodies fight off infection. It is found in many foods, including wheat-based products, meats, beans and nuts.

    Children typically eat more than one serving of cereal or snack bars a day, in addition to taking vitamin supplements. Eating large amounts of these nutrients can be dangerous to kids' health. Too much vitamin A can cause liver damage, and high levels of zinc can destroy the body's natural immunity, or power to fight infection.

    The EWG authors are calling for the FDA to make changes to its guidelines for nutrient intake and revise its daily values to match kids' diets.

    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.

    It was a Sunday evening, and everyone was doing their own thing —whatever my sisters and I like to do during our1time. Mom told us to come to the living room. Like most children, of course, we wanted to2whatever we were doing. I don't remember3I was doing, only that I was the last one to go into the4room. Abbey was in a chair, and Elizabeth was by the wall, closest5the stairs.

    I don't remember where everyone else was sitting,6 it was one of the very few times my Dad was with us while we had7. He is usually at work or always busy with something. Mom told us that they were getting a8When she first told us, I didn't know what to think. But when Elizabeth started laughing, all my sisters and I started9, because we truly thought she was joking, or maybe we just didn't10Elizabeth to get mad at us. Looking back, I think the main11 I laughed with them was because I didn't12what to think.

    Mom insisted that she wasn't13, and that she wouldn't joke about something serious; for we wouldn't 14her if something of the sort would15happen. We all stopped laughing, and Elizabeth was the first to get16. She was angry that they were getting a divorce. She went upstairs in17, and then I also got upset. I don't really remember much18Elizabeth went upstairs, but I know that I19the living room so I could be 20.
