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.

    Chinese double amputee (截肢) climber Xia Boyu received the most votes {#blank#}1{#/blank#} (global) to become the 2019 Laureus Sporting Moment of the Year winner on Monday.

    Xia came out from an initial list of 10 nominees before three finalists were made {#blank#}2{#/blank#} (know) to the public earlier this month.

    Xia had lost both his legs in 1975 during his first attempt to reach {#blank#}3{#/blank#} world's highest peak of Qomolangma due to frostbite. He challenged the summit in 2014, 2015 and 2016 {#blank#}4{#/blank#} well, but his dreams {#blank#}5{#/blank#} (break) owing to avalanche, earthquake and bad weather respectively.

    Xia finally made {#blank#}6{#/blank#} in his fifth attempt on May 14, 2018, becoming the first Chinese double amputee climber {#blank#}7{#/blank#} (reach) the summit of Qomolangma.

    "Climbing to the summit of Qomolangma is always a dream and goal for me. I {#blank#}8{#/blank#} (fight) for it over the past decades. Despite bad knocks several times, I never gave up. I think the determination made my life so colorful and {#blank#}9{#/blank#} (meaning)," Xia told Chinese media.

    Xia added that his next goal will be "7+2", namely the highest summits of seven {#blank#}10{#/blank#} (continent), plus the South Pole and North pole.

    It is a great{#blank#}1{#/blank#}(true) that life is difficult. Once we really understand and accept it, then life is no longer difficult. {#blank#}2{#/blank#}, most of us do not fully see it. They just complain about their problems and difficulties as if life should be easy.

    {#blank#}3{#/blank#}makes life difficult is that the process of facing and solving problems is a really painful one. Problems, {#blank#}4{#/blank#}(base) on their nature, cause sadness or regret or anger or fear. These are {#blank#}5{#/blank#}(comfort) feelings, often as painful as any kind of physical pain. It is in the whole process of solving problems {#blank#}6{#/blank#} life has its meaning. Problems are the serious test that tells us success from failure. When we want to strengthen the growth of human spirit, we encourage the human ability {#blank#}7{#/blank#}(solve) problems, just as in school we set problems for our children to deal with. {#blank#}8{#/blank#}(learn) from the pain of meeting and working out problems is{#blank#}9{#/blank#}great benefit. As Benjamin Franklin said, “Those things that hurt, instruct.” For this reason, wise people learn not to fear but to welcome{#blank#}10{#/blank#} pain of problems.

    Now, I'd like to tell you about the development of computers. Computers began {#blank#}1{#/blank#} a calculating machine in France in 1642, it could {#blank#}2{#/blank#} (simple) difficult sums. In 1936, Alan Turing wrote a book about how a computer could be made to work as a "universal Machine" {#blank#}3{#/blank#} (solve) any difficult mathematical problem. By the 1940s, computers had grown as large as a room. As time went by, they were made {#blank#}4{#/blank#} (small). Since the 1970s computers {#blank#}5{#/blank#} (use) in offices and homes, first as personal computers and then as laptops.

    As computers' memory improved, computers became much smaller and more {#blank#}6{#/blank#} (intelligence). First the memory was stored in tubes, then on transistors and later on very small chips. Over time computer's memory {#blank#}7{#/blank#} (develop) so much that computers remember everything they have been told. In the early 1960s computers could be connected to each other by the network {#blank#}8{#/blank#} (call) the World Wide Web.

    Many new {#blank#}9{#/blank#} (apply) have been found for computers since the1970s. They have been used in communication, finance, trade, robots, mobile phones, space rockets and so the goal of computers is to provide humans {#blank#}10{#/blank#} a life of high quality.

    Generally speaking, a motto is a short and suggestive {#blank#}1{#/blank#} (express) of a guiding principle, {#blank#}2{#/blank#} can inspire people to work for self-betterment. My motto is "God helps those who help {#blank#}3{#/blank#} (they)". Sometimes I am lazy and don't want to work, {#blank#}4{#/blank#} the moment I think of my motto I will become {#blank#}5{#/blank#} (energy) again and devote myself to {#blank#}6{#/blank#} I am doing. I write my motto where I can see it {#blank#}7{#/blank#} (easy). Every time {#blank#}8{#/blank#} (face) with difficulty, I will {#blank#}9{#/blank#} (inspire) with much confidence by the sight of my motto. My motto also makes me become {#blank#}10{#/blank#} independent person. My friends, what is your motto?
