Henry is carried out to sea by a strong wind but {#blank#}1{#/blank#} (spot) by a ship, on which he earns his passage by working without pay. As a result, he is brought to London. Feeling hungry, he {#blank#}2{#/blank#} (wander) alone on the streets, hoping for {#blank#}3{#/blank#} job.

    Then unexpectedly he is {#blank#}4{#/blank#} (invite) to a large and beautiful house by two rich brothers, Roderick and Oliver. They give a(n) envelope {#blank#}5{#/blank#} a bank note in it to him.

    They have made a{#blank#}6{#/blank#}(secretly) bet on whether a man can {#blank#}7{#/blank#} (survival) a month in the city with a million-pound bank note. Henry is the person they want.

    He feels surprised at first and doesn't want {#blank#}8{#/blank#}(accept) it, for he just wants an honest job from them, not {#blank#}9{#/blank#}(they) charity. The two brothers persuade him to take it at last, however. Though feeling very {#blank#}10{#/blank#}(surprise) about the matter, Henry promises them not to open the letter until one and a half hours later.

    Kids who use media in unhealthy ways may have problems {#blank#}1{#/blank#}relationships, conduct and other emotional symptoms, lead author of a US new study warned.

    A study of the University of Michigan (UM){#blank#}2{#/blank#} (release) recently on its website found that how children use the devices, rather than how much time they spend on them,{#blank#}3{#/blank#} (be) the strongest predictor of emotional or social problems connected with screen {#blank#}4{#/blank#}(addict ).

    The study revealed that {#blank#}5{#/blank#}matters most is whether screen use causes problems in other areas of life or has become{#blank#}6{#/blank#}all-consuming activity.

    Some of the warning {#blank#}7{#/blank#} (sign) include: if screen time interferes with daily activities, causes conflict for the child or in the family, or is the only activity {#blank#}8{#/blank#}brings the child joy. Though much research{#blank#}9{#/blank#} (exist) on adolescents and screen use, this is considered as the first tool to measure how addicted children are to screen media. It will be a{#blank#}10{#/blank#} (value) tool for parents, clinicians and researchers.

    As populations increased in large cities in {#blank#}1{#/blank#} nineteenth century, building subway lines was a way {#blank#}2{#/blank#}(move) people from one area of a city to another quickly and efficiently. The first major subway system, the London Underground, {#blank#}3{#/blank#}(start) in 1873 using steam trains. Subways caught on quickly in London. From 1896, it was changed in favor of an electrical system. Today's subways around the world now work on {#blank#}4{#/blank#}(electrical). Passengers can rely on the regular schedule of subway trains while {#blank#}5{#/blank#}(avoid) traffic on busy city streets.

    Two of the world's earliest subways were built in Paris and New York. When the Paris Metro opened on July 19, 1900, citizens were proud of the {#blank#}6{#/blank#}(impress) and beautifully decorated station entrances.{#blank#}7{#/blank#} the first New York subway consisted {#blank#}8{#/blank#} only 14.5 kilometers of track in 1904, today, it is the world's largest subway system.

    Today, subways are still popular with passengers. The Tokyo subway is the {#blank#}9{#/blank#}(busy) in the world, with 3.2 billion riders a year. Close behind {#blank#}10{#/blank#}(be) subways in Moscow(2.4 billion), Seoul (2.1 billion), and New York City (1.6 billion).

    When the construction of the new factory came to the end in {#blank#}1{#/blank#} European village, a pump was put in. Then, all the settlers {#blank#}2{#/blank#} (defeat) by a severe disease {#blank#}3{#/blank#} characteristic was similar to cholera. An expert physician who was instructed to attend to the victims and handle this case showed great enthusiasm, {#blank#}4{#/blank#} he didn't foresee that it was a hard challenge. After simple enquiry, he announced that it was the {#blank#}5{#/blank#} (pollute) water that made the people {#blank#}6{#/blank#} (suffer) from the disease. But without positive {#blank#}7{#/blank#} (evident), people suspected and rejected his view, {#blank#}8{#/blank#} (say) the theory he put forward made no sense. Being much {#blank#}9{#/blank#} (strict) with himself than before, he contributed himself to the case. Apart from making enquiries, he made detailed charts and analyzed the data carefully. Finally, he drew a scientific {#blank#}10{#/blank#} (conclude), linking the disease to the radium in the pump. He found out why people there got sick immediately.
