It can be easy for some of teenagers to form bad habits. These bad habits, if     1     (leave) unchecked, could lead to more serious ones when they become adults. To prevent harmful habits like these from     2     (支配) a teenager’s life is essential. To change bad habits is never easy, even with many     3     (attempt). Aristotle once said: “We are     4     we repeatedly do.” We make a choice to do something, and then we repeat     5     over and over again. Soon that choice becomes automatic and forms a habit. The good news is that we can change by understanding how habits work. we must first learn about the “habit cycle”, which works like this: Firstly, a “cue”, an action, event, or situation. Then a “routine”, the regular action you take     6     response to the cue. Thirdly, there is the “reward”.

    7     (facilitate) a positive change in our bad habits, we must first examine our bad habit cycles and then try to adapt them. Many of us try to change bad habits quickly, and if we are not successful, we often become     8     (悲观的) and give up. In fact, the most successful way to change is not suddenly, but over a period of time. As the Chinese philosopher Lao Zi wrote, “A journey of a thousand miles     9     (begin) with a single step.” To reach the goal of change, a person must show some d     10     . After all, it is not easy to break bad habits.

In reality,    1     (使我们震惊的是，主语从句) large amounts of food have been wasted in restaurants and canteens. Food waste can not only lead to the environment’s being polluted     2     (而且引发更为严重的食物短缺). 3.     3     (考虑到这个令人苦恼的情况), a campaign has been launched in the past months to     4     (阻止学生们浪费粮食).     5     (对于我们学生来说，少点食物比浪费食物更重要，主语从句). Now,   with students forming the habit of cleaning their plates, we are     6     (convince) that our school canteen will soon be kept free of wasted food.

For me, education has three main o    1    . Firstly, it is to gain knowledge. Obviously, certain kinds of knowledge are necessary not only to     2     (追求) certain careers but also to contribute to the world.

Some Chinese parents like to set examples for their children, encouraging them to follow these examples. They like to compare their own children with     1     .

I dislike my parents comparing me with those who are better at something than me. They always look up to them and say that I’m worse than them.     2     it may encourage me to work harder, it will make me lose heart.

Am I really worse than others? Of course     3    . I am interested in Chinese and western history and I’m the king of stories in my class. Besides, as a fan of art, I draw pictures in my free     4     and sell them for money to help poor kids. But my parents can’t see that. All of my classmates hate “the children of others’ families”. So it’s a big problem. We just want our parents to cheer us up     5     of comparing us with others.

I know it’s not just me. Our culture is full of comparisons, and it’s very     6     for us not to look around at what other people are doing, what progress they are making. But all these years I’ve learned one thing: Whatever     7    , you must believe in yourself. Don’t give up. Just keep on doing your important work and     8     to be better and better.

In February, the Ministry of Education suggested that mobile phones should be banned(禁止) in primary and secondary schools. Almost all parents clap their hands     1     it's good both for students'eyesight and for their schoolwork. But how would students feel schools banned phones in class?

Xu Xiaohe, a 13-year-old girl from Zhejiang supports the policy. “In fact, my school has     2     allowed us to bring our mobile phones,” Xu said, “My teachers always believe that playing with phones is a     3     of time, compared with reading and doing sports. Adults can't control themselves, let alone kids.”

Li Zihan from Bejjing, however, thinks that the ban is too simplistic for a generation that has grown up with mobile phones. “Students should be     4     self-management skills, as well as learn how to use their phones effectively to help with their school life.”

For Ge Ziqi, the problem with banning phones has more to do with life     5     school. The 13-year-old Beijinger uses a bike-sharing app every day to travel between her home and school. “Today, no     6     ways are more convenient than paying by phone, from taking a bus to buying food,” she said, “If I can't take my phone with me, I'll have to buy a bicycle of my     7    .”

To solve the problem like Ge’s, some ideas teachers have come up with     8     really well. At Shanghai Shatian School, for example, students are asked to put their phones in special lockers(储物柜). The students call these lockers the “phone farm” (“养机场”) or phone Tarmac” (“停机坪”).
