In most people's mind, hackers(黑客)may seem bad and dangerous. But Wang Zhengyang, an eighth-grader might change your thoughts. He only wants to {#blank#}1{#/blank#} (保护) your computers.

    Wang is the youngest hacker in China. On September 25th, Wang gave a {#blank#}2{#/blank#}(演说) at the 2014 China Internet Security Conference(中国互联网安全大会) in Beijing. The 13-year-old became the youngest member {#blank#}3{#/blank#}(在……之中)the people from all over the world.

    Wang started his study at the age of 8. {#blank#}4{#/blank#}(自从……以来) then, he has been learning computer language by {#blank#}5{#/blank#}(他自己). Most of it was {#blank#}6{#/blank#} (写) in English and this helped improve his English.

    To be a hacker, sometimes some {#blank#}7{#/blank#}(网站) were not allowed to visit. But he hoped to find their weakness and offer help. In the past five years, Wang has {#blank#}8{#/blank#}(修补) more than 100 bugs(漏洞). As for the future, the young hacker wishes to {#blank#}9{#/blank#}(继续) his study at university to know more about the world of computer language.

    As for hacking, Wang prefers to be called White Hat, who offers help {#blank#}10{#/blank#}(而不是) of bringing trouble to computers.

    "It's just like doctors who help people. We are good hackers," said Wang to The Beijing News.

    Flies(苍蝇) are one of the most dangerous enemies of human. They are dangerous because they carry diseases(疾病) , Flies do not care whether the food they eat is d{#blank#}1{#/blank#}or clean. The food they like best is o{#blank#}2{#/blank#}the dirtiest that can be found. Then they may f{#blank#}3{#/blank#}into a house where good clean food is kept and begin to walk all over it and eat it. Soon the good clean food becomes unfit(不合适) for people to eat. Often a person who is preparing f{#blank#}4{#/blank#}does not realize that it is unfit for people to eat, so the food is put on the t{#blank#}5{#/blank#}and eaten. Those who eat such food become dangerously ill. That's why we must get rid of(消灭) flies.
