A recent study suggests that students who bring water into exams may improve their grades by 10 percent．

    Scientists then {#blank#}1{#/blank#} (比较) their exam results with their normal schoolwork grades．They found that all those {#blank#}2{#/blank#} had brought drinks with them got better grades．

    Scientists also considered the students 'schoolwork and {#blank#}3{#/blank#} (预计)their grades．This was to make sure that the reason was not simply that smarter students were more {#blank#}4{#/blank#} (有可能)to bring drinks with them．

    {#blank#}5{#/blank#} is unclear why drinking water improves exam results．But scientists say having enough water in our b{#blank#}6{#/blank#} and not feeling thirsty could have a helpful effect {#blank#}7{#/blank#} our brains．Drinking water may also cut d{#blank#}8{#/blank#} on anxiety ,which affects exam performances．

    So next time， w{#blank#}9{#/blank#} you are going to have a big exam，try bringing a bottle of water with you．Who knows—it may help you p{#blank#}10{#/blank#} the exam!

    Born into {#blank#}1{#/blank#} poor family in Gaomi, Shandong Province on February 17, 1955, Mo Yan,{#blank#}2{#/blank#}original name is Guan Moye, threw himself into reading and calligraphy{#blank#}3{#/blank#}(enthusiastic) in his early years. Not only did he have a strong sense of humor,{#blank#}4{#/blank#}he was intelligent and patient. With his attention {#blank#}5{#/blank#} (fix) on literature, Mo Yan went on further education and received a Master's Degree in arts from Beijing University five years later after graduating from the PLA Academy of Arts in 1986. What happened next was{#blank#}6{#/blank#}he won China's {#blank#}7{#/blank#} (high) literary prize — Mao Dun Literature Prize by his book Frog in 2011. To all Chinese's{#blank#}8{#/blank#}(amaze), he became the first Chinese writer to be awarded the Nobel Prize in Literature in 2012, which will certainly make great contributions to development of Chinese literature. Since then, he {#blank#}9{#/blank#}(consider) as the best Chinese writer in modern China. Although he is famous, he is still as common as an old shoe and he doesn't keep his readers{#blank#}10{#/blank#}a distance.

    According to a recent study, plants are able to make intelligent decisions. They are a lot{#blank#}1{#/blank#}(smart) than we thought. Scientists have discovered that the pea plant can make decisions on how{#blank#}2{#/blank#} (survive) best, even though it does not have a brain. Researchers grew several pea plants that had their roots {#blank#}3{#/blank#} (separate) between two pots. Each pot contained different amount of nutrients. One pot always had the same amount{#blank#}4{#/blank#}the other pot varied between a lot and a little. The plants turned out to be{#blank#}5{#/blank#} (amaze) consistent（一致的）at turning their roots to the pot with the most nutrients.

    Researcher Alex Kacelnik says the experiment raises a question, not about plants{#blank#}6{#/blank#} about animals and humans. He wonders whether the pea plant is more efficient in using its limited resources about {#blank#}7{#/blank#}(make) decisions than humans. He says, “We have a very wonderful brain, but maybe most of the time we're not using {#blank#}8{#/blank#}” Professor Kacelnik does not think that pea plants are intelligent in the human sense, but that they exhibit complex{#blank#}9{#/blank#} (behave) to efficiently take advantage of natural opportunities. It will be interesting to see how our lives would be different if we{#blank#}10{#/blank#} (adopt) similar strategies.

    Everyone has dreams, but not all dreams can be realized. People give up their dreams for this or that reason. Those {#blank#}1{#/blank#} dreams become true have one thing in common, that is, they insist on {#blank#}2{#/blank#} (work) for their dreams.

    Marie Curie, a famous scientist, has set {#blank#}3{#/blank#} good example. In 1898, Marie {#blank#}4{#/blank#} (find) a new element (元素) in the pitchblende (沥青铀矿). {#blank#}5{#/blank#} (prove) her discovery, she had to show it to the world, which also became her dream. After using tons of pitchblende, Marie and her husband {#blank#}6{#/blank#} (final) saw the blue light of radium (镭). There are many other examples. Athletes who gain gold medals and students who enter key universities after {#blank#}7{#/blank#} (year) of hard work, are all dream-holders.

    The path to dreams may not be smooth and the progress may be {#blank#}8{#/blank#}(pain). But hold on to your dreams, no matter {#blank#}9{#/blank#} big or small they are. Hold on to the end, and you will find there is nothing {#blank#}10{#/blank#} (happy) than your dreams coming true.
