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!

    A motto is a sentence or a phrase which can inspire us especially when we are {#blank#}1{#/blank#} (face) with difficulties. Many of us use well-know {#blank#}2{#/blank#} (say) as mottos, such as “Where there is a will, there is a way.” Or “nothing is difficult if you put your heat into it.”, and so on. My motto is “God helps those who help{#blank#}3{#/blank#} Sometimes I am lazy {#blank#}4{#/blank#} don't want to make efforts to work hard, but the moment I think of my motto I will get{#blank#}5{#/blank#}(energy) again and devote myself to what I am doing. I write my motto {#blank#}6{#/blank#} I can see it easily. Every time I fail in my exam and begin to lose heart, the sight of my motto inspires me {#blank#}7{#/blank#} much confidence. My motto also makes me become an {#blank#}8{#/blank#} (dependent) person. That is to say, I won't rely on others {#blank#}9{#/blank#} (easy). My friends, what is your motto? If you still haven't got a motto, please choose {#blank#}10{#/blank#} because a motto can have a great effect on you.

    There are various festivals throughout the world, festivals to satisfy and please the {#blank#}1{#/blank#}(ancestor), to honor some famous people or important events, and {#blank#}2{#/blank#} (express) people's thanks to the God {#blank#}3{#/blank#} bringing them harvest. For example, in Mexico people observe the Day of the Dead in early November, {#blank#}4{#/blank#} people eat food in the shape of skulls and cakes with “bones” on them. In India, October 2 is {#blank#}5{#/blank#} national festival to honour Mohandas Gandhi who helped India become a(n) {#blank#}6{#/blank#} (depend) country. And in China, the Spring Festival, which {#blank#}7{#/blank#} (celebrate) in January or February, is the most {#blank#}8{#/blank#} (energy) and important because it is a festival that looks forward to the coming of spring. {#blank#}9{#/blank#} are there all these festivals? Because during the festivals, people can get together to eat, drink and have fun with each other, {#blank#}10{#/blank#} (forget) all the daily struggle and demands for a while.

    It's so close, and yet it always seemed so far away. {#blank#}1{#/blank#}(get) to the rural district just a few hundred {#blank#}2{#/blank#}(meter) away on the other side of the bay, native people used to have to jump on a boat or drive about 160 kilometers－part of that journey on {#blank#}3{#/blank#}(dust) road.

    Now anyone wanting to get from downtown Maputo, capital of Mozambique, to Katembe, or vice versa, can do so easily, and in a matter of minutes, thanks to the longest twin­tower suspension bridge in Africa, {#blank#}4{#/blank#} hangs over Maputo Bay.

    "Mozambique had long planned to build a bridge linking the north and south of the bay, but nothing came of them because {#blank#}5{#/blank#} a lack of money and technology,"  said Wang Lijun, vice­president of China Road and Bridge Corporation (公司), which built {#blank#}6{#/blank#} bridge.

    The Maputo­Katembe Bridge, {#blank#}7{#/blank#}(open) in November after four years of construction, is part of the Maputo Bridge and Link Roads project which {#blank#}8{#/blank#}(build) by CRBC. It {#blank#}9{#/blank#}(be) 187 kilometers long and serves as an important highway that directly links Maputo to the border with South Africa, to the south.

    "By night, when the lights are on, it's {#blank#}10{#/blank#}(especial) impressive," Wang said, and as a landmark it could help develop tourism and attract overseas investment for Mozambique.
