The Spring Festival, also known as the Lunar New Year, is the most important {#blank#}1{#/blank#}(tradition) festival in China, which falls in late January or early February.

    The historical reason for beginning the New Year in such a time is{#blank#}2{#/blank#} it is the time between autumn harvest and spring plowing and planting. In other words, it is the time for rest, relaxation and celebration after a year's hard work.

    Except this practical reason for celebrating the Spring Festival, a popular Chinese legend offers another {#blank#}3{#/blank#} (explain), which is {#blank#}4{#/blank#} (general) accepted in China. In ancient times, a devil called “Nian” that lived under the sea would attack people once a year on the eve of the New Year. It jumped out from the sea and attacked villages{#blank#}5{#/blank#} (eat) people, animals and plants. As they could no longer bear Nian's cruel persecution（迫害）, the villagers gathered {#blank#}6{#/blank#} (discuss) how to deal with Nian and some people suggested that the devil was afraid of loud noises, red color and flame. So people {#blank#}7{#/blank#} (light) firecrackers and fireworks, put up red couplets on{#blank#}8{#/blank#} (they) gates and beat drums to drive Nian away. The idea worked{#blank#}9{#/blank#}Nian ran away.

    Since ever, the custom and tradition of celebrating the Spring Festival has formed and the practices of putting up red couplets on gates, setting {#blank#}10{#/blank#} firecrackers and fireworks, etc. have been passed down.

    As you know, science plays {#blank#}1{#/blank#} very important role in our education. Do you want to keep up with the latest research and discoveries in science? There are many good websites {#blank#}2{#/blank#} you can check out the latest in the science world.

    One great site is Science News for Kids. This site reports science news {#blank#}3{#/blank#} (cover) a wide range of subjects. The articles are intended {#blank#}4{#/blank#}younger readers， {#blank#}5{#/blank#} adults will find this site suitable for them as well. Another wonderful site, one that I check out every day,{#blank#}6{#/blank#}(call) Science Daily. The site is {#blank#}7{#/blank#} (constant) updated with news, often about exciting {#blank#}8{#/blank#} (finding) that change how we view the world.

    These sites post the latest stories and also keep all the past articles they{#blank#}9{#/blank#} (post) earlier. That way you can find about {#blank#}10{#/blank#}is related to the science fields your are interested in.

    Contrary to {#blank#}1{#/blank#}some people might assume, evidence {#blank#}2{#/blank#}(show) that sharks seldom attack humans. There are three types of shark attacks. In the main type, the shark attacks you because it mistakes you {#blank#}3{#/blank#} a fish, {#blank#}4{#/blank#}when it tastes human flesh it decides  {#blank#}5{#/blank#} (give) up and swims away. In the second type, the shark {#blank#}6{#/blank#}(push) you with{#blank#}7{#/blank#}nose to find out if you are fit to be eaten, and then bites you{#blank#}8{#/blank#}it thinks you are. In the third type, the shark waits for you to swim by, and then attacks you all of{#blank#}9{#/blank#}sudden. The last two types of attack more often result in the {#blank#}10{#/blank#}(die) of humans.

    You may not have noticed it before, but many people often sit with a hunched (驼背的) back when they are in a difficult situation, such as trying hard {#blank#}1{#/blank#} (solve) a math problem. But there's a reason for this: this body position helps to reduce pressure.

     However, according to Erik Peper, a health professor at San Francisco State University, poor posture (姿势) may make our brains work not as well as they {#blank#}2{#/blank#} (normal) do.

    Peper and a team of researchers {#blank#}3{#/blank#} (study) 125 students' performance in a math test and their different postures. The team found that good posture—for example sitting up straight—could help people perform better {#blank#}4{#/blank#} bad posture when they feel stressed.

    Another professor Richard Harvey further explained in Science Daily that sitting with bad posture might make us feel more {#blank#}5{#/blank#} (comfort), but it actually increases our pressure levels.

    So the next time you have to take a test, try sitting upright and taking a deep {#blank#}6{#/blank#} (breathe). If Peper's study is correct, this small change may have {#blank#}7{#/blank#} great influence on you.

    There are many things {#blank#}8{#/blank#} lead to poor posture. The good news {#blank#}9{#/blank#} (be) that posture can be improved at any age by {#blank#}10{#/blank#} (make) just a few simple corrections in the way one stands, sits and moves.
