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.

    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.

    Many of us love July because it's the month when nature's berries and stone fruits are in abundance. These colourful and sweet jewels form British Columbia's fields are little powerhouses of nutritional protection.

    Of the common berries, strawberries are highest in vitamin C, although, because of their seeds, raspberries contain a little more protein (蛋白质), iron and zinc (not that fruits have much protein). Blueberries are particularly high in antioxidants (抗氧化物质). The yellow and orange stone fruits such as peaches are high in the carotenoids we turn into vitamin A and which are antioxidants. As for cherries (樱桃), they are so delicious who cares? However, they are rich in vitamin C.

    When combined with berries of slices of other fruits, frozen bananas make an excellent base for thick, cooling fruit shakes and low fat “ice cream”. For this purpose, select ripe bananas for freezing as they are much sweeter. Remove the skin and place them in plastic bags or containers and freeze. If you like, a squeeze of fresh lemon juice on the bananas will prevent them turning brown. Frozen bananas will last several weeks, depending on their ripeness and the temperature of the freezer.

    If you have a juicer, you can simply feed in frozen bananas and some berries or sliced fruit. Out comes a “soft-serve” creamy dessert, to be eaten right away. This makes a fun activity for a children's party; they love feeding the fruit and frozen bananas into the top of the machine and watching the ice cream come out below.

    This player is neither the answer to Bafana Bafana's goal-scoring problem, nor holds any hope of being in the national team for the World Cup. But Mmane Koko trains every morning and is now used to playing soccer. She said, 'Before I can do my domestic(家庭的) jobs, I go to train every morning. This helps me keep my body healthy. I started exercising after my doctor told me that exercising can keep my body healthy.'

    Mmane Koko, aged 66, said if she had been exposed to soccer at an earlier age, she would have become a top South African striker and could have stolen the limelight from Noko Matlou, who helped South Africa achieve its best ever result in the African women's soccer cup. She encourages young people to start playing sports early and to continue into their old age as it helps to lower blood pressure and prevent obesity(肥胖症).

    She added that because soccer is not only about exercising, but also helps one to put bread on the table, it could make a difference socially. She also says soccer is a business and that clubs these days pay generously. Therefore if the young take sports seriously, they can make a living out of it. But this can only happen if our government participate in developing sports and building stadiums for future generations.

    Exercise does us a lot of good as Mmane Koko says. We can live longer and feel better through exercise. It gives us energy surprisingly enough! Regular exercise reduces our risk of all kinds of disease. It can help us relieve stress and anxiety, increase our endurance(耐力) and sleep better. Exercise can contribute to our mental well-being and helps treat depression. So if you want to stay fit, keep on exercising to keep your body healthy.

    Robots are increasingly being developed to think and act like humans. But it is difficult for engineers to create humor (幽默) in machines. Computer scientists have hoped to help them understand humor. But they failed again and again. Why is it so difficult?

    Kiki, a computer language expert (专家), studies humor at a university. "Most robots are powered by artificial intelligence (人工智能AI). But AI will never understand jokes like humans do." He said, "The main problem is that AI system doesn't have the sense of humor."

    Other experts agree that context (语境) is very important to understand humor, both for humans and robots. In one project, Tristan Miller, a computer scientist, studied more than 10, 000 puns. Puns are a kind of joke that uses a word with two meanings. For example, you could say, "Balloons (气球) do not like pop music." The word "pop" can be a way of saying popular music, or "pop" can be the sound a balloon makes when it explodes(爆炸). "A robot might not understand the joke because it doesn't know the meaning of the puns." Miller said.

    Although it's difficult, some scientists say there are good reasons to keep trying to teach humor to robots. It can make machines understand humans better and serve humans better. And it can also help them to think more like humans.

    But other scientists don't think it's a good idea to teach humor to robots. They may find humor, but they may use it in a wrong way. Maybe bad Al will start killing people because it thinks it is funny. Besides, it may make some people feel not safe. The comedians(喜剧演员) may lose their jobs when the robots can understand humor.

    To find out how the name Canada came about we must go back to the 16th century. At that time, the French dreamed of discovering and controlling more land, of expanding(扩大) trade beyond their borders and of spreading their beliefs across the world. In 1535, Francois I, king of France, ordered a navigator(航海家) named Jacques Cartier to explore the New World and search for a way to India.

    Carrier first arrived at the gulf of the St. Lawrence, which he intended (打算) to explore. He did not know what to expect but he hoped that this gulf was just an arm of the ocean between two islands. If it was, he would soon be on his way to the Far East. So he sailed upstream along the St. Lawrence River. However, instead of reaching Asia he arrived at Quebec or Standalone, as the Indians called it. It was at this point that the term "Canada" entered the country's history. Apparently the word "Canada" came from an India word" kanata", which means community or village. Cartier first used it when he referred to Standalone or Quebec. What a huge "village" Canada is!

A group of small, waggling (扭动) robots that communicate by flashing lights can make collective decisions. This is similar to the process bees use to reach an agreement on where to build their nest.

"We believe that in the near future there are going to be simple robots that will do jobs that we don't want to do, and it will be very important that they make decisions on their own," says Carmen Miguel at the University of Barcelona in Spain. She and her team tested how copying bees might help with that.

When bees go house-hunting, they communicate their preferred locations through a "waggle dance". The more a bee recommends one location, the longer and harder it waggles. Eventually other bees join them, and they reach an agreement when a majority are waggling together. Researchers previously translated this behavior into a mathematical model, and Miguel and her colleagues used it to program decision-making rules into small robots called kilobots.

Each kilobot with three thin legs had an infrared-light emitter (红外线发射器) and receiver, and a colored LED light. Within a group, kilobots could move around, turn clockwise or anticlockwise and use infrared signals to exchange information.

Ezequiel Ferrero at the University of Barcelona says that across all the experiments, kilobots reached an agreement within about half an hour, even when they didn't have many immediate neighbors to communicate with. He says that getting the right combination of how long they spend transmitting their message and how much they walk around allowed them to make a collective decision in the end.
