In the time of Queen Victoria, cholera, a deadly disease, hit London, which often resulted in large numbers of {#blank#}1{#/blank#}(dead). John Snow, a then well-known doctor, became{#blank#}2{#/blank#}(inspire) when he thought about helping ordinary people who {#blank#}3{#/blank#}(expose) to cholera. John Snow thought {#blank#}4{#/blank#}most important was to find its cause. He got interested in two theories {#blank#}5{#/blank#}(explain) how cholera killed people. He believed in the second theory{#blank#}6{#/blank#}suggested people absorbed the disease with their meals. He began to gather information and made a map, on which he marked {#blank#}7{#/blank#}the victims(受害者)had lived. As a result, he found out that the {#blank#}8{#/blank#}(pollute)water was the cause of cholera and suggested that the source of all water supplies{#blank#}9{#/blank#}(examine)immediately. Finally, “King Cholera”{#blank#}10{#/blank#} (defeat).

    I was on my way home with a friend yesterday {#blank#}1{#/blank#}I found a mobile phone by the roadside. After picking it up, I started searching the contact list and called numbers {#blank#}2{#/blank#} (see) whether I could figure out whose phone it was {#blank#}3{#/blank#}(fortunate), the only person who answered the phone didn't recognize {#blank#}4{#/blank#} number that I was calling from. My friend suggested that we go back to the street and the house in front of which we found the mobile phone. And we did so. I knocked at the door and two young men answered. {#blank#}5{#/blank#}of them had lost their phones, but as I referred to some names on the contact list, one of them said he also had those names {#blank#}6{#/blank#} that it must be the phone of one of their friends. Then, he took the phone and said how{#blank#}7{#/blank#}(wonder) it was that I took the time to find the owner. Afterwards, I left without leaving my name or address. I never considered keeping the phone. Instead, I immediately tried to find the owner. And I believed that was exactly{#blank#}8{#/blank#}I would want someone to do if I lost my phone. It couldn't have been {#blank#}9{#/blank#}(good).

    Sometimes, {#blank#}10{#/blank#}(help) others is just doing the right thing.

    There were many great philosophers in ancient China. Confucius stressed the significance of {#blank#}1{#/blank#} (kind), duty and order in society, {#blank#}2{#/blank#} ideas influenced Chinese society for over 2, 000 years.

    Mencius was a student of Confucius's ideas. His teachings were similar to {#blank#}3{#/blank#} of Confucius. He {#blank#}4{#/blank#} (bring) up by his mother and had an important position in the government of {#blank#}5{#/blank#} state. He believed man is good, that people would be good if government was kind, and {#blank#}6{#/blank#} people were more important than rulers. Mencius wrote a book {#blank#}7{#/blank#} (call) The Book of Mencius in his last years.

    Mozi was also an {#blank#}8{#/blank#} (influence) thinker, whose beliefs were similar to Confucius's {#blank#}9{#/blank#} some ways. Born into a poor family, he became famous for his unusual clothes and behaviour. Because he considered that government was most important, he spent many years {#blank#}10{#/blank#} (try) to find a state where people would follow his teaching. He believed all men were equal.

    Household garbage sorting and recycling has become a hot topic in Shanghai because of China's first compulsive garbage-separation law {#blank#}1{#/blank#} every household and institution shall classify waste into four {#blank#}2{#/blank#}(category). Those who fail to sort garbage may {#blank#}3{#/blank#}(fine) up to 200 yuan.

    Previously, everything went into one bin, so this change has made many people very {#blank#}4{#/blank#}  (worry), who said they were struggling to master the details quickly.

    Now thanks to the efforts of {#blank#}5{#/blank#} number of young programmers, discovering the proper classification for each piece of household waste has become as simple as taking a photo {#blank#}6{#/blank#} calling someone using your smartphone.

    They have applied speech and image recognition technologies {#blank#}7{#/blank#} apps and other smartphone services to guide Shanghai residents through the garbage-separation rules.

    Most of the apps and services, which {#blank#}8{#/blank#} (begin) springing up last month in app stores, on messaging tool WeChat and mobile payment service Alipay, allow users to type in the name of waste {#blank#}9{#/blank#}(identify) which category it belongs to. Many apps also use speech and image recognition to make the process much easier, but their creators say they will disappear in time with the Chinese {#blank#}10{#/blank#}(become) more accustomed to the rules.
