Running a few kilometers each day is good for our health. However, new research says running too much could be bad for us. Running long distances {#blank#}1{#/blank#}(regular) for many years could make our life{#blank#}2{#/blank#}(short), not longer. The study is from the Minneapolis Heart Institute. A researcher said too much running can created plague(斑) inside your heart,{#blank#}3{#/blank#}can lead to heart disease. He wrote that running too much for many years takes away the good things from exercise. He{#blank#}4{#/blank#}(add) that the risk of heart disease could be{#blank#}5{#/blank#}same as someone who never exercised.

    Researchers looked{#blank#}6{#/blank#}the health and training of 3,300 runners over the age of 35. 70% of them ran over 30 kilometers a week. Men who ran marathons for 25 years had 62% more plaque in their heart than men who did little{#blank#}7{#/blank#}no exercise. Another doctor said he felt cheated. He started running marathons in 1967. He used{#blank#}8{#/blank#}(run) 60 kilometers every week. He said, “I thought I was out there exhausting{#blank#}9{#/blank#}(me), building an absolutely strong heart.” The doctor advised{#blank#}10{#/blank#}(exercise) frequently but not to overdo things.

    Lasa Bailey took her gloves off when {#blank#}1{#/blank#}（take）her dog for a long walk on a winter day and didn't notice anything until that evening. She was shocked when she realized her beautiful anniversary ring was missing. She {#blank#}2{#/blank#}（hurry）back to look for it but couldn't find anything. Her husband kept going on a website where people sell jewelry, {#blank#}3{#/blank#} never found it.

    All that changed, however, thanks to a recent Facebook post {#blank#}4{#/blank#}（write）on their local police department's page. A woman police officer posted, “If anybody knows of anybody losing a diamond ring, please contact us. ”One of her friends read it and wrote on it “Lisa Bailey”.

    The police station happened to find some unidentified {#blank#}5{#/blank#}（jewel）in a local pawn shop（当铺）and took them away. When Bailey learned from her friend that her ring might {#blank#}6{#/blank#}（find）, she couldn't believe it.

    The police called Bailey and asked her to describe it. She sent a picture of it to {#blank#}7{#/blank#} and then they asked if she could come to the police station. When the police officer in the station {#blank#}8{#/blank#} had written the Facebook post handed her the ring the next day, she was very thrilled and started to tear up. She could wear her anniversary ring home where it belongs {#blank#}9{#/blank#}（final）after three years'wait.

    Bailey's husband had offered to replace the ring after it went {#blank#}10{#/blank#}（miss）, but she refused because she thought it wouldn't be the same.

    Can you imagine waking up each day in a house that is {#blank#}1{#/blank#} (gentle) rocked by the movement of water? Well, for some people this vision of the future may become a reality.

    It is a commonly accepted fact that {#blank#}2{#/blank#} the Earth's temperature rises, the ice caps at the North and South Poles will melt, {#blank#}3{#/blank#} (cause) the sea level to rise.

    So, where does this leave the many countries in the world {#blank#}4{#/blank#}have large sections of their populations living in areas which lie at or below sea level? The Netherlands, for example, is one of {#blank#}5{#/blank#} most highly populated, low-lying countries and {#blank#}6{#/blank#} (battle) with the problem of flooding for years. Further rises in the sea level would result in much of the country disappearing under water.

    Inventive architects may have come up with a {#blank#}7{#/blank#} (solve) to the problem: a house actually built on the water. The basic idea is that houses will have a base {#blank#}8{#/blank#} (fill) with air and a way of anchoring(使固定) them to the ground. This will allow the house {#blank#}9{#/blank#} (move) upwards whenever the sea level rises and sink back down when the sea level drops. So, will {#blank#}10{#/blank#} (float) houses be the homes of the future? For some people there may be no alternative.

    When the Spanish explorer Cortez reached Mexico in the sixteenth century, he found people there using a drink {#blank#}1{#/blank#} was called chocolate. It tasted quite strong because it had pepper in it. {#blank#}2{#/blank#} (make) it taste better, the Spanish added sugar. When chocolate first came to Europe in the seventeenth century, people {#blank#}3{#/blank#} (start) to drink it with milk, instead of water. Nowadays, tons of chocolate {#blank#}4{#/blank#} (deliver) to factories, where they are turned into many popular sweets and cakes.

    A 23-year-old British woman has invented a product made {#blank#}1{#/blank#} combining fishing waste and algae(海藻).It could be used to replace plastic bags, {#blank#}2{#/blank#} people use once and throw away. Lucy Hughes created the material, called MarinaTex. On November 13, Hughes {#blank#}3{#/blank#} (award) the international winner of the 2019 James Dyson Award for design.

    MarinaTex is stronger, {#blank#}4{#/blank#} (safe) and much more sustainable than the plastic polyethylene(聚 乙烯).But unlike plastic, MarinaTex is also easier {#blank#}5{#/blank#} (break) down in four to six weeks in normal conditions and does not pollute the soil. Concerned about the growing amounts of plastics in ocean waters, she is investigating ways to reduce the amount of waste from the fishing industry, which produces {#blank#}6{#/blank#}(approximate) 50 million tons of waste worldwide each year.

    {#blank#}7{#/blank#} (examine) fish parts left over from processing helped to give her the idea for a material that was useful and did not harm the environment. After months of testing, Hughes {#blank#}8{#/blank#}(produce) a strong, flexible sheet that forms at temperatures below 100 degrees Celsius.

    Hughes will receive about $41,000 in prize money as the first place {#blank#}9{#/blank#} (win) of the James Dyson Award. She plans to use the money to further develop the product and ways to mass produce {#blank#}10{#/blank#}
