It's very important for everyone to protect the environment. As a student, I always try my {#blank#}1{#/blank#} to save energy at home. I turn off {#blank#}2{#/blank#}  when I don't need them. And I try to save water when I wash the dishes. I don't {#blank#}3{#/blank#} bottles or newspaper away because it's better to recycle them.
I think everyday activities at home can make a difference to the environment. I feel proud of {#blank#}4{#/blank#}, and I will not only keep saving energy but also advise others to do the same things as me. If everyone cares about {#blank#}5{#/blank#} the environment, I'm sure we'll have a better life.

    ZhangMing, a college graduate from Shandong, created a 9-page"Wechatguide". With drawings and simple words, the step-by-step guide e{#blank#}1{#/blank#} how to send messages, take pictures and make video calls. Zhang made the guide for his parents. "My parents are getting old. They need an easy way to learn how to use technology, "he said.

    Zhang's experience is c{#blank#}2{#/blank#} nowadays.Worldwide,40percent of parents learn about new technologies, including computers, mobile Internet and social media, from their children, according to a study from the International Communication Association in 2017.

    Parents u {#blank#}3{#/blank#} to teach their kids about almost everything. Now for the first time, the teachers become the students, and the students turn into the teachers.

    The c{#blank#}4{#/blank#} of the roles comes from the rapid development of society and technology says Zhou Xiaohong, a sociology professor from Nanjing University. Zhou said the Internet and other forms of media give children ways to get information b{#blank#}5{#/blank#}  from asking older generations. Therefore, in the age of information, it's possible that children know more than their parents do.

    According to the China Internet Network Information Center, 56.7 percent of Internet users and 67.2 percent of social media users in China are under the age of 30. The younger generation u{#blank#}6{#/blank#} acts as a link between their family and the new environment. But when they teach their parents new technologies, parents can connect to the new world by themselves, noted Zhou.

    In Zhang Ming's eyes, teaching his parents about Wechat brings him c{#blank#}7{#/blank#} to his parents."People can communicate more by using new technology. Why should we keep our parents out? "said Zhang.

    A good trick doesn't leave lasting damage and always makes people laugh. It can even amaze them with its creativity. Some schools and universities have a long{#blank#}1{#/blank#}of students playing good tricks. These tricks sometimes include school buildings and cars.

    The California Institute of Technology, a university in the US, has a special day on which students are{#blank#}2{#/blank#}to play big tricks. One time, a group of students took part a car, moved the parts into a student's room and then put the car back together next to the bed.
