Exercise could not only benefit your body, but also improve your memory, researchers found{#blank#}1{#/blank#}(recent).

    In their paper, researchers in the United States and Japan{#blank#}2{#/blank#}(introduce) their experiment and conclusion.

    Scientists invited 36 volunteers{#blank#}3{#/blank#}were in their early 20s to do 10 minutes of light exercise before taking a memory test in which they{#blank#}4{#/blank#}(show) pictures like broccoli(西兰花) or picnic baskets and asked to recall them later. The same experiment was repeated with the same group of volunteers without exercising. “The memory task really was quite{#blank#}5{#/blank#}(challenge),” said Michael Yassa, co-author of the study. “ We used very similar items to see if they would remember {#blank#}6{#/blank#}it was this exact picnic basket versus that picnic basket.”

    Researchers also scanned brains of some of the participants during the experiment.

    They found increased communication between parts{#blank#}7{#/blank#}(involve) in the storage and recollection of memories in brains of those who had exercised.

This suggested that just 10 minutes of light exercise might have a positive effect {#blank#}8{#/blank#}memory power.

    As all{#blank#}9{#/blank#}volunteers in the experiment were relatively young, researchers are still working{#blank#}10{#/blank#}(look) at the influence of light exercise on older people. “Our main goal is to try to develop an exercise way that can be used by older adults who might have disabilities,” said Yassa.

    In China, the history of people planting and using bamboo can date back as far as 7000 years. As early as the Shang Dynasty, bamboo was being used in ancient peopled dally lives. It was used for food, clothing, housing, transportation, {#blank#}1{#/blank#} (music) instruments and even weapons.

    The {#blank#}2{#/blank#} (apply) of bamboo in science and technology is thrilling. In 251 BC, Li Bing, in Sichuan, {#blank#}3{#/blank#} (lead) the local people in building the Dujiang Weirs, the first irrigation network in the world, in which bamboo played {#blank#}4{#/blank#} important role. The world's oldest water piper was also {#blank#}5{#/blank#} (make) of bamboo. During the Han Dynasty, the people in Sichuan {#blank#}6{#/blank#} (success) sank a 1600-metre-deep well with thick bamboo ropes. This technology did not spread to Europe {#blank#}7{#/blank#} the 19th century, and it was by using the technology {#blank#}8{#/blank#} the Americans drilled the first oil well in Pennsylvania in 1859.

    In Chinese culture, bamboo is well-known as {#blank#}9{#/blank#} of the "four gentlemen" in plants. To many distinguished men, bamboo is a symbol of goodness and honesty. It is always closely related to people of positive spirits. Bamboo culture contributes to encouraging People to hold on when {#blank#}10{#/blank#} (face) tough situations.

    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.

    We've all heard that breakfast is {#blank#}1{#/blank#} most important meal in the day. It may actually be true. Recently, a study of more than 50,000 adults aged 30 and older{#blank#}2{#/blank#}(find) that people who have breakfast are more likely to lose{#blank#}3{#/blank#}(weigh) than those who don't eat a morning meal. Other studies connect not eating breakfast{#blank#}4{#/blank#}a higher risk of high blood pressure, heart disease and so on.

    However, it's not just when you eat that matters, but{#blank#}5{#/blank#}you eat also matters. {#blank#}6{#/blank#}(keep)fit, you should have a balanced diet with protein, fiber and healthy fats, which is the key to a satisfying{#blank#}7{#/blank#}nutritious breakfast . If you want to keep{#blank#}8{#/blank#}(you) from being hungry later of the day, you'd better eat within 90 minutes after waking up. Also, coffee drunk on an empty stomach is not recommended because it can be{#blank#}9{#/blank#}(harm)to your body.

    There is an old saying that advises "Eat breakfast like a king, lunch like a prince, and dinner like a beggar. It is worth{#blank#}10{#/blank#}(follow).
