My mother and my brother were taking a trip to Washington, D.C. They came back with the most{#blank#}1{#/blank#}(amaze) story I have ever heard!

    When they passed by New York, their train failed to work{#blank#}2{#/blank#}(proper), the conductors asked everyone to move forward to another train. When everyone{#blank#}3{#/blank#}(seat), my mother realized she didn't have her handbag, in {#blank#}4{#/blank#}was her money, tickets, credit card and license. She rushed to a conductor. “Excuse me, I left my bag on the other train. Can you stop the train?” The conductor replied, “Oh, I'm sorry,{#blank#}5{#/blank#}we cannot let you off.” My mom quickly picked up her cellphone,{#blank#}6{#/blank#}only thing she had, and started calling someone for help but{#blank#}7{#/blank#}vain.

    Luckily, when the train finally stopped in Delaware, a man left the train and handed my mom $ 112. My mother thanked him and felt grateful for his {#blank#}8{#/blank#}(kind). She got the man's address and promised{#blank#}9{#/blank#}(find) a way to pay him back. My mother and my brother finally arrived in Washington, D.C., but did not get to do all the things as{#blank#}10{#/blank#}(plan). They got to take a few like rides, buy souvenirs, and more. They made the best of the worst vacation!

    Driving to the airport in the early morning. I felt{#blank#}1{#/blank#} (excite) because I would spend the summer in Paris. While{#blank#}2{#/blank#} (look) for more interesting things to do besides sleeping and eating on the plane, I jumped at the chance to study French in this city know for{#blank#}3{#/blank#} (it) art, food and culture.

    My connecting flight(转机) was in Frankfurt, Germany, 14 hours from Denver. But when I arrived there, a feeling of anxiety{#blank#}4{#/blank#} (begin) to set in. I was very nervous {#blank#}5{#/blank#} I was in a country {#blank#}6{#/blank#} language I could not speak. But when I found my way, I gained {#blank#}7{#/blank#} (confident). When I boarded the second plane and discovered that the flight was less than an hour, I was filled{#blank#}8{#/blank#} excitement.

    When I stepped on foreign ground for the first time, I was{#blank#}9{#/blank#} (extreme) happy. I quickly had my first experience trying to communicate in {#blank#}10{#/blank#}language that I had only practised in school. As I left the airport, with one sharp turn, the Eiffel Tower came into view. I was fully in Paris.

    John Snow was a well-known physician in London in the 19th century. {#blank#}1{#/blank#} famous was he that he even attended Queen Victoria to ease the birth of her babies. However, he decided to defeat cholera, a {#blank#}2{#/blank#} (dead) disease at that time when he saw thousands of people {#blank#}3{#/blank#} (expose) to it died every time there was an outbreak.

    In 1854 when cholera broke out, he began to gather information and marked on a map {#blank#}4{#/blank#} all the dead people {#blank#}5{#/blank#}（live）. He found many people who had drunk {#blank#}6{#/blank#} dirty water from the pump died. So he decided that the polluted water carried cholera. He found a woman and her daughter who had the water {#blank#}7{#/blank#}（deliver） from the pump every day died of cholera after drinking the water. {#blank#}8{#/blank#} this extra evidence John Snow announced that the polluted water was {#blank#}9{#/blank#}（blame）. He suggested the source of all water supplies should be examined and new methods of {#blank#}10{#/blank#}（deal）with water be found. Finally, “King Cholera” was defeated.

    Teenagers have long been told that being active and {#blank#}1{#/blank#}(take) part in sports is good for their health. But new research suggests that too much sport for teenagers could negatively affect their well-being just as much as too {#blank#}2{#/blank#} sport.

    The US Department of Health and Human Services suggests that young people {#blank#}3{#/blank#}(age) between 6 and 17 work{#blank#}4{#/blank#}at least 60 minutes a day, 7 hours a week. But researchers from Switzerland say their study suggests that 14 hours of physical activity a week is best for promoting good health in teenagers. However, more than 14 hours {#blank#}5{#/blank#} (appear) to be harmful to their health. To reach their findings, they had 1,245 teenagers {#blank#}6{#/blank#}(survey) in their research.

    All participants (参与者) were required to answer questions about height and weight, sports practice, sports {#blank#}7{#/blank#} (injure) and well-being. Their well-being was measured using the Word Health Organization (WHO) Well-being Index, {#blank#}8{#/blank#} provides scores between 0 and 25. Of the participants, 50.4% were male. Almost 9% of these males were overweight. The overall {#blank#}9{#/blank#}well-being score for all participants was 17.

    The researchers divided sports participants into low, average, {#blank#}10{#/blank#}, and very high. The researchers found that participation in the low and very high activity groups were more likely {#blank#}11{#/blank#} (have) well-being scores below 13, compared with participants in the average group. The researchers found that the highest well-being scores were {#blank#}12{#/blank#} a by participants who carried out around 14 hours of physical activity a week, but beyond 14 hours resulted {#blank#}13{#/blank#} lower well-being scores.

    The researchers suggest that doctors {#blank#}14{#/blank#} care for teenagers should check their level of sports practice. Teenagers {#blank#}15{#/blank#} (probable) need a supportive and closer follow-up of their health and well-being.

    Former First Lady Michelle Obama's memoir (回忆录) Becoming has become the best-selling book {#blank#}1{#/blank#} ( publish) this year in the US just 15 days after publication. The sales figure (two million copies){#blank#}2{#/blank#} (announce) by Penguin Random House last Friday.

    Becoming mainly tells the story about {#blank#}3{#/blank#} Michelle has balanced work and family {#blank#}4{#/blank#} a professional woman. The book is {#blank#}5{#/blank#} window into the personal life of the first African-American First Lady and the first black US President. About marriage, Michelle mentions, “I married a creative thinker, and I had to remind {#blank#}6{#/blank#}(I) that we were adapting to each other to make two individuals a solid, permanent us.” In the memoir, Michelle speaks {#blank#}7{#/blank#} (honest) of difficulties she met with in her life. The 54-year-old also criticizes (批评) US President Donald Trump, {#blank#}8{#/blank#} (write) that she can “never forgive” him. That's because during his presidential campaign. Trump's “birther” theory that Michelle's husband was not born in the US {#blank#}9{#/blank#} therefore was not a legal President put her family's {#blank#}10{#/blank#} (safe) at risk.
