—Yes, he is a {#blank#}1{#/blank#} hero.

    A teacher once told each of her students to bring a clear plastic bag and a large bag of potatoes to school. {#blank#}1{#/blank#} every person that the students refused to forgive in their life, they {#blank#}2{#/blank#}(choose) a potato, wrote on {#blank#}3{#/blank#} the name of that person and the date, and then put it in the plastic bag. Some of their bags were quite heavy.

    They were then told to carry these bags with them everywhere for one week,{#blank#}4{#/blank#} (put) them beside their beds at night, on their car seats when driving, and next to their desks at work.

    During this time,{#blank#}5{#/blank#} they carried the bags around with them, they realized what a weight they were carrying, and{#blank#}6{#/blank#}they needed to pay attention all the time, so as not to forget them or leave them in {#blank#}7{#/blank#} (embarrass) places. Of course, the potatoes were becoming {#blank#}8{#/blank#} (rot), and smelled very bad.

    This is the same as the price we pay for keeping our pain and {#blank#}9{#/blank#} (happy) with us! Forgiving others is not only a gift to them, but also a very good gift to {#blank#}10{#/blank#}！

    Have you ever wondered{#blank#}1{#/blank#}children always seem to have bags of energy and never run out of steam? Researchers have discovered that children have the levels of recovery of endurance athletes. In fact, scientists say children's muscles recover from "high-intensity exercise" a lot{#blank#}2{#/blank#}(quick) than athletes. A study looked at the performance levels of children when they were cycling, and compared their fitness to {#blank#}3{#/blank#}of athletes. Researcher Dr Sebastien Ratel suggested they {#blank#}4{#/blank#} (find) the children used more of their aerobic metabolism and were therefore less tired during the high-intensity physical activities. The children also recovered very quickly-even faster than the well-trained adult endurance athletes.

    The researchers hope that{#blank#}5{#/blank#}(they) findings will help scientists have a better{#blank#}6{#/blank#}(understand) how the human body changes with age. It could lead to advances in the fight {#blank#}7{#/blank#} diabetes and other diseases. Dr Ratel said the research was{#blank#}8{#/blank#}(particular) important as more children were become less active. He warned: "With the diseases related to physical inactivity{#blank#}9{#/blank#}(rise), know the changes with growth that might contribute to the risk of disease. "{#blank#}10{#/blank#}is helpful for children to maintain their fitness as they grow up and play as much as they could so they remain healthy as adults.
