Kids and food: advice for parents

    It is important for parents to know how to help their kids eat healthy. Here are a few easy ways.

    Parents control the supply lines.

    {#blank#}1{#/blank#} Though kids may keep asking for less nutritious foods, parents should decide which foods are regularly provided in the house. Kids won't go hungry. They'll eat what's available in the fridge at home.

    Say goodbye to “clean-plate club”.

    {#blank#}2{#/blank#} Lots of parents grew up under the clean-plate rule, but that way doesn't help kids listen to their own bodies when they are full. When kids feel full, they're likely to overeat.

    {#blank#}3{#/blank#}

    Food preferences are developed early in life, so try to offer different kinds of food. Likes and dislikes begin forming even when kids are babies. Parents may need to serve a new food on several different occasions(时机) for a child to accept it.

    Food is not love.

    Find better ways to say “I love you.” When foods are used to reward kids and show love, they may start to turn to food when feeling worried or unhappy. {#blank#}4{#/blank#}

    Kids do as you do.

    {#blank#}5{#/blank#} When trying to teach good eating habits, try to set the best example. Choose nutritious food, eat at the table, and don't forget breakfast.

A. Start them young.

B. Rewrite the kids' menu.

C. Be a role model and eat healthy yourself.

D. Offer praise and attention instead of food treats.

E. Let kids stop eating when they feel they've had enough.

F. You decide which foods to buy and when to serve them.

G. Let kids choose what to eat and how much of it they want.

Study Habits You Should Be Practising

    With exams, essays, projects, and many deadlines for different things, effective（有效的）study habits are necessary. {#blank#}1{#/blank#} If you are in need of a bit of an improvement, keep reading for the top four study habits that you should be practicing.

    ⒈Make and use flashcards.

    {#blank#}2{#/blank#} By using flashcards with a question on one side and the answer on the other, you will force your brain to recall he necessary information. Even if you struggle a bit with a card, you will still be actively revising the necessary material.

    ⒉Revise, revise, revise!

    Many students put off studying until just before the exam, with the more hardworking students giving themselves a week or two before a test. {#blank#}3{#/blank#} It's best to revise the information a little bit every day, so that you are not upset when a test comes around.

    ⒊{#blank#}4{#/blank#}

    One of the most effective—and the most fun—methods of studying is to watch related lectures and videos in order to get more material. Watch documentaries or videos on YouTube and educational websites. You may be surprised at how much you can learn from videos, and just how much information is available online.

    ⒋Re-write your notes.

    Studies have shown that writing information out by hand increases your ability to remember the material. This makes the recall go hand-in-hand with muscle memory.{#blank#}5{#/blank#}

    These are the four most effective study habits, and something all successful students do. Make sure you are on top of your game by following these study methods!

    As long as people have been telling stories, crones(丑陋的老太婆)have been scaring the wits out of children. "Nags(怨妇),witches, evil stepmothers, cannibals(食人妇). It's quite dreadful," says Maria Tatar, who teaches a course on folklore and mythology at Harvard. "But old women are also powerful—they're often the ones who can work magic." In the Disney film Snow White, there's a scene in which the beautiful, charming, wicked queen turns into an old hag and poisons Snow White so she'll sleep forever. The old lady in Hansel and Gretel wants to roast children in her oven and the witch in The Little Mermaid cuts out Ariel's tongue.

    Tatar says old women villains (恶人)are especially scary because，historically, the most powerful person in a child's life was the mother. "Children do have a way of splitting the mother figure into...the evil mother—who's always making rules and regulations, policing your behavior, getting angry at you—and then the kind mother—the one who is giving and protects you, makes sure that you survive."

    Veronique Tadjo, a writer who grew up in the Ivory Coast, thinks there's a fear of female power in general. She says a common figure in African folk tales is the old witch who destroys people's souls. Still, they're not all bitter and evil hags. Elderly women in folk tales often use their knowledge and experience of the world to guide the troubled protagonist(主人公). Tadjo points to the Kenyan story Marwe In The Underworld about a girl who commits suicide by drowning herself and enters the Land of the Dead where she meets an old woman. "That old woman teaches her quite a lot of things," Tadjo says. "And also, when Marwe starts longing for the world of the living, she helps her go back to the surface with a lot of riches. And we understand that Marwe has been rewarded for her goodness." In other words: Do your chores and you'll be rewarded. The point of these ancient tales, no matter what continent they come from, may have been to scare children into behaving.

    Perhaps the scariest old woman character—the ugly Baba Yaga—comes from Russia. She's bony with a hooked nose and long, iron teeth. Her hut(小屋)stands on chicken legs and she kidnaps children and eats them. Safe to say Baba Yaga has been making Eastern European children sleepless for centuries. In one interpretation, a mean stepmother sends the young girl Vasilisa to Baba Yaga's hut in the woods to get a candle. The girl is sure she's being sent to her death. Baba Yaga forces her to cook and clean, and Vasilisa does everything she's told. In the end, the old crone gives her what she needs and sends her home. "You see this kind of double face of the hag,"Maria Tatar says. "On the one hand: aggressive, threatening. And on the other hand: sometimes to make sure that there is a happily ever after."

    There's that power again. In Japanese folklore, the Yama Uba(山姥)is an equally ambiguous old woman. She's a mountain witch who, like Baba Yaga, lures people into her hut and eats them. But she'll also help a lost traveler. Noriko Reider is a professor at Miami University of Ohio who's done extensive research on Yama Uba stories. "She brings fortune and happiness," Reider says. "She can also bring death and destruction for those who are not very good."

    According to Cuban-American writer Alma Flor Ada, in Hispanic(拉美地区的)culture old women are multi-talented. Ada is co-author of Tales Our Grandmas Told, which includes a story about Caliph's son who becomes seriously ill. After "all of the best physicians in the land" fail to cure him, Caliph sends his messengers searching for help. Then one morning, an old woman arrives with this advice: To get well, the prince must wear the overcoat of a man who is truly happy. And of course it works.

    Recently, I have read a great number of books. I have found that no reading every day has helped me in my study Reduce Stress  {#blank#}1{#/blank#} And I am sure no matter what I read, the act of it will also improve yours.

    Reduce Stress {#blank#}2{#/blank#} Fiction is great for this. Reading an interesting fiction book is perfect right before bed time, though sometimes it's hard to put the book down if it's really good. Still, you'll be relaxed.

    Improve Analytical Thinking A scientific study shows that analytical thinking is encouraged and improved by reading. Readers improve their general knowledge, and more importantly are able to recognize patterns quicker.  {#blank#}3{#/blank#} Increase Vocabulary It's no secret that reading increases your vocabulary and improves your spelling.  {#blank#}4{#/blank#} In fact, even the language in children's books is likely to be more sophisticated(老练，复杂) than your daily conversation.

    {#blank#}5{#/blank#}

    I feel like a better writer, as I am burying myself in works from people who are better than me. That's why English classes in High School make you read “the classics". That's why art students learn to copy those masterpiece(态作), so they know the feeling of creating something amazing. The more you read the better of a writer you'II become.

    If you think that you don't have enough time to start reading, you're wrong. Think about the time you spend on TV series and in chatting online. Why not replace reading with those activities.? Well, let's start to read and get improved.

A. Improve Writing Skills

B. Change Writing Habits

C. When I have a stressful day, reading can easily help me relax.

D. Here are a few of my favorite ways that reading has helped me

E. But did you know that reading increases your vocabulary more than talking or direct teaching?

F. If you can recognize pattems quicker, your analytical skills get improved.

G. You will be surprised at the vocabulary you use in your daily conversation.

    Why Ultra-pure(超高纯的)Water Is Actually Bad for Your Health Many people are surprised to hear that drinking purified water on a regular, daily basis is actually dangerous. So why is 100% ultra-pure water not good for us? {#blank#}1{#/blank#}

    There is no such thing as truly pure water in the natural world. {#blank#}2{#/blank#}When these minerals dissolve(溶解)in water, they form what we commonly refer to as electrolytes(电解质).They allow us to perform all the "bioelectrical" functions such as moving, heart-beating, thinking, and seeing.

    But pure water fails to provide these fundamental electrolytes. {#blank#}3{#/blank#}You can think of it this way: imagine a room with no gravity, split in half down the middle. You throw a couple hundred balls into the left side of the room. {#blank#}4{#/blank#} But if you cut a bunch of holes in the barrier, they will slowly start to spread over to the right side. Eventually, they will be evenly distributed across the entire room.

    The water in your organs stays at very specific levels of minerals. When you drink ultra-purified water, it pulls the minerals out of your blood just like the right side of the space room pulled some of the bouncy balls over from the left. {#blank#}5{#/blank#}

    Purified water can only be recommended as a way of drawing poisons out of the body. Once this is accomplished, the continued drinking of purified water is a bad idea.

A.Purified water is an active absorber.

B.Since there's no gravity, they bounce around everywhere.

C.It actually tries to rob your body of them when you drink it.

D.Even water in the purest lakes contains small amounts of minerals.

E.If you drank enough of it, the lack of minerals would eventually kill you.

F.The simple answer is that ultra-pure water doesn't provide the natural minerals we need.

G.This is why materials tend to move from more concentrated areas to less concentrated ones.

Benefits and Problems of Genetic Engineering

    Plant breeding is the science of changing the characteristics of plants in order to produce desired ones. Genes in a plant are what determine what type of characteristics it will have. Plant breeders try to create a specific outcome of plants and potentially new plant varieties by changing the genes of the plants through breeding, which is making new plants from parents of different varieties or species.

    Actually, plant breeding has been practiced for thousands of years, since near the beginning of human civilization. It is practiced worldwide by individuals such as gardeners and farmers and by professional plant breeders employed by organizations such as government institutions, universities, crop-specific industry associations or research centers. They have crossbred plants to create the new types of plants that are, for example, bigger, stronger, or more attractive.

    Crossbreeding can take such a long time, however, and it is inaccurate. Now, we can change exact sections of Deoxyribonucleic acid (DNA), so the process is more accurate and faster. But people all over the world are arguing about its benefits and disadvantages. Some people use the technology to produce desired characteristics of plants and animals. Other people are concerned that the genetically engineered plants may harm the environment and worried that they may be dangerous for people to eat.

    There are many reasons for changing plants in this way. International development agencies believe that breeding new crops is important for ensuring food security by developing new varieties that are higher yielding(高产的), disease resistant, drought tolerant or regionally adapted to different environments and growing conditions. For example, some genetically engineered plants can live through frost or draught. As a result, famers can make more profit because fewer plants will die.

    Some genetically engineered plants are more nutritious. They have less fat, taste better or stay fresher than non-genetically engineered plants. This will allow people to buy better-quality fruit and vegetables.

    Some genetically engineered plants can resist natural pests such as viruses or insects. This reduces the amount of chemical needed to kill pests, which is helpful to the environment.

    However, genetically engineered plants can cause unexpected problems. Genetically engineered plants that resist pests may pass on that characteristic to a wild relative. This may cause the wild plant to spread fast, because pests are not naturally killing it.

    Genetically engineered plants can also harm animals. A type of corn has been developed which kills a species of insect that destroys it. The pollen (花粉) from this corn, however, can also kill monarch butterflies—the most beautiful of all butterflies, which do not harm the corn.

    To ensure the most adapted varieties are identified, advocates of organic breeding now promote the use of direct selection for many desired characteristics.

    Genetic engineering is a very new science and we have a lot to learn about the good it can do and the damage it can cause. The main concern is that not enough tests are being done to ensure it is safe.
