John Snow was a famous doctor in London — so expert that he attended Queen Victoria as her personal physician. But he became inspired when he thought about helping ordinary people {#blank#}1{#/blank#} (expose) to cholera,{#blank#}2{#/blank#}  was the deadly disease of its day. Neither its cause nor its cure was understood. So many thousands of terrified people died whenever there was {#blank#}3{#/blank#}outbreak. John Snow wanted to face the challenge and solve this problem. He knew that cholera would never {#blank#}4{#/blank#}(control) until its cause was found.

    He became interested in two theories that {#blank#}5{#/blank#}(possible) explained how cholera killed people. The first suggested that cholera multiplied in the air. A cloud of dangerous gas floated around until it found its victims. The second suggested that people absorbed this disease {#blank#}6{#/blank#} their bodies with their meals. From the stomach the disease quickly attacked the body and soon the {#blank#}7{#/blank#}(affect) people died. He suspected the second theory was correct {#blank#}8{#/blank#} he needed evidence.

    So when another outbreak hit London in 1854, he was ready to begin his {#blank#}9{#/blank#}(enquire). As the disease spread quickly through poor neighborhoods, he began to gather information. In two particular streets, the cholera outbreak was so severe that more than 500 people died in ten days. He determined {#blank#}10{#/blank#}(find) out why.

    Recently a really strange thing happened in a middle school in China's Hubei Province. Over 600 students there took part in a "caring for an egg like a baby"{#blank#}1{#/blank#} (active), in which they were asked to keep an egg close at hand for a month{#blank#}2{#/blank#}breaking it.

    "It's hard for parents to bring up their children {#blank#}3{#/blank#} many students just ignore it," said Liu Kang, the school's director. "They should {#blank#}4{#/blank#} (teach) to be grateful to their parents, who have given them life but ask for nothing in return."

    Li Ming is one of the students. His egg didn't break during the month, but he felt   {#blank#}5{#/blank#}(exhaust). "I now understand what great difficulty my parents have had{#blank#}6{#/blank#}(bring) me up. I'll do all I can to make their life easier and {#blank#}7{#/blank#} (comfort) when I grow up," promised the 13-year-old boy.

    {#blank#}8{#/blank#}(luck), about 450 students broke their eggs. Yan Yueming broke his egg after just five days, which made him frustrated. He said, "I can't imagine {#blank#}9{#/blank#} sad my parents would be if there was something wrong with me, their 'egg'! It is now time I {#blank#}10{#/blank#}(do) something in return for their love," said Yan.

    Eyes closed, she felt the cool breeze on her face as the car drove past the green grassland. The breeze gave her a sense of {#blank#}1{#/blank#}(free) and happiness. The breeze suddenly {#blank#}2{#/blank#}(come) to a stop with the car stopping due to the traffic {#blank#}3{#/blank#}(create) by sheep. Climbing out of the car in excitement, she realized she was in a new world in {#blank#}4{#/blank#} her only companion was the beauty of nature all around her. {#blank#}5{#/blank#}(stand) there, she finally understood the meaning of happiness! She thought she was the {#blank#}6{#/blank#}(happy) person in the world at that moment.

    In this fast­paced world, we've forgotten the simple pleasures in life. Just stop for a moment to ask yourself how long it has been since you sat down for a while, {#blank#}7{#/blank#}(absolute) doing nothing but still feeling perfectly happy? People tend to find happiness in goods or {#blank#}8{#/blank#}(thing) around them. But the perfect place to start searching for happiness is right within you! True happiness is said to be achieved when we are the reason behind a person's beautiful smile and huge happiness!

    So {#blank#}9{#/blank#} next time you see someone upset or feeling low, lend them a bit {#blank#}10{#/blank#} your time and support. It doesn't cost much, but doubles the happiness in your heart!

Digital technology is being increasingly adopted {#blank#}1{#/blank#} (carry) out economic and social activities, and is deeply transforming production patterns and people's lifestyles. However, it is important that the adoption of digital technology in developing countries does not {#blank#}2{#/blank#} (wide) the rich-poor gap.

E-commerce (电子商务) promotes growth in incomes' for the poor. China has the world's fastest-growing e-commerce market, {#blank#}4{#/blank#} more than 40 percent of global e-commerce transactions (交易) take place.
