    Do you have any idea of New Year paintings?{#blank#}1{#/blank#} (know) as “paper paintings” and “painted pictures”, New Year paintings are a special art form in Chinese folk culture. Without New Year paintings, our traditional Chinese folk culture would be much less {#blank#}2{#/blank#}(color). The paintings get such a name because they are {#blank#}3{#/blank#}(most) posted during the Chinese New Year holiday for {#blank#}4{#/blank#}(decorate) and they are also accepted as a symbol of New Year's greetings.

    New Year paintings appeared around the Tang dynasty, replacing the previous door pictures believed to be able to protect the residents and drive away ghosts.

    Way back in 1674, a frog helped Antoni van Leeuwenhoek make an incredible discovery. Antoni was an amateur scientist from Holland, so fascinated by microscopes {#blank#}1{#/blank#} he'd built some of his own. One rainy day, as he went for a walk, a leaping frog {#blank#}2{#/blank#}(draw) his attention to a puddle.

    Antoni collected a drop of puddle water and put it{#blank#}3{#/blank#} his microscope. He was amazed{#blank#}4{#/blank#} (see) a whole community of creatures swimming in this one drop — tiny beings no one had ever seen before.

    These tiny beings, called microbes, are everywhere: in dirt, in food and on your kitchen table. People {#blank#}5{#/blank#} (cover) in them, too.{#blank#}6{#/blank#} you were to count all the microbes on and inside your body, you would find your body has more microbes than the world has people — over 6 billion!

    Microbes can't survive on {#blank#}7{#/blank#}(they) own. They need food. After {#blank#}8{#/blank#}(settle) into a home — you, for instance — they steal vitamins and other nutrients and leave behind dead cells and poisonous liquids called toxins. Some microbes can make you sick. People usually call these ones germs{#blank#}9{#/blank#} (lucky) for you, there are more {#blank#}10{#/blank#} (help) microbes, working together to keep you healthy, than bad ones.

    My favorite color is orange. It is a warm and bright color, and it makes me feel happy and safe. When I {#blank#}1{#/blank#} (see) this color, I think of fall. When I go outside, I enjoy{#blank#}2{#/blank#} (walk) through the dark orange leaves and listening to the sound they make under my feet. I also think of the smell of fire. It's great to be at home and sit by the warm fire with{#blank#}3{#/blank#} (I) family. This warm and beautiful color should be everywhere this season!

    According to a review of evidence in a medical journal, runners live three years {#blank#}1{#/blank#}(long) than non-runners. You don't have to run fast or for long{#blank#}2{#/blank#}(see) the benefit. You may drink, smoke, be overweight and still reduce your risk of {#blank#}3{#/blank#} (die) early by running. While running regularly can't make you live forever, the review says it {#blank#}4{#/blank#} (be) more effective at lengthening life{#blank#}5{#/blank#} walking, cycling or swimming. Two of the authors of the review also made a study published in 2014{#blank#}6{#/blank#}showed a mere five to 10 minutes a day of running reduced the risk of heart disease and early deaths from all {#blank#}7{#/blank#}(cause).

    The best exercise is one that you enjoy and will do. But otherwise… it's probably running. To avoid knee pain, you can run on soft surfaces, do exercises to{#blank#}8{#/blank#}(strength)your leg muscles(肌肉),avoid hills and get good running shoes. Running is cheap, easy and it's always{#blank#}9{#/blank#}(energy).If you are time poor, you need run for only half the time to get the same benefits as other sports, so perhaps we should all give{#blank#}10{#/blank#}a try.
