With the rapid development of China’s     1    and new technology, China has already       2    its poverty (贫穷) and the Chinese people have become     3    wealthy (富有). As a result, more foreign people including     4    from high schools are     5    in to come for sightseeing, to do business, or to learn new technology. Martin Mahanmad, a boy at the age of 16, after     6    from junior high school, was admitted to a local senior high school and two years later came to a high school in Beijing as an     7    student. In the beginning, he came across a great many difficulties, but as time goes on, with the help of his Chinese classmates, he has already     8    living in China. Now Martin can speak       9    Chinese.

Some years ago, Martin met a tourist from China, from whom he learnt that China was a country with 5, 000 years of     10    , powerful but friendly.

He also learnt China’s science and technology in the history was very     11    all over the world, and most importantly, ninety     12    of the high school students in China are studying hard for a brighter future.

Originally Martin’s parents wanted him to go to Japan but after a careful     13    , Martin chose China    14    Japan. He believed that nothing could       15    him from going to study in China.

If you logged on to weibo over the weekend, chances are that your web page was     1     with videos of US celebrities dumping ice water on their heads. It seems that everyone is getting in for fun, from popular singers like Taylor Swift and Justin Timberlake, to high-ranking of tech executives including Bill Gates and Mark Zuckerberg.

Is it some kind of new, cool way to cope with the summer heat? Of course not. It’s a fundraising game called the Ice Bucket Challenge, and it aims to raise     2     for Amyotrophic Lateral Sclerosis(ALS肌萎缩性脊髓侧索硬化症，亦称“渐冻人症”).

The challenge’s     3     is straightforward. It involves daring a person to dump a bucket of ice water over his head within 24 hours, or donate money for fighting against ALS. Even if a person completes the challenge, they’re more than welcome to donate money anyhow.

Once a person completes the challenge, they’re supposed to issue the same challenge to several other people, usually three, which is why the challenge has been growing and growing.

Since the beginning of June, the game has spread across social media timelines and late-night talk shows in the US. According to Facebook, more than 15 million people so far have posted,     4    , or liked a post about the challenge. It has raised more than $2.3 million (14 million yuan) to support research for the illness.

As for the origins of the craze, new data from the Facebook data science team heavily supports one theory: that the ice bucket challenge     5     with Pete Frates, a former captain of the Boston College baseball team. Frates, 29, who was diagnosed with ALS in 2012, can no longer speak and uses a wheelchair. After Frates posted his own ice bucket challenge video on July 31, the game took off and has now become one of the biggest activities in the online community.

The challenge went popular on social media, particularly in the United States, with people, celebrities, politicians and athletes posting videos of themselves online and on TV     6     in the event. But before the challenge, public awareness of the disease was relatively     7    .

Of course, ice bucket challenges need to be undertaken with at least basic     8     and common sense. Those who tip the water need to be     9     enough — and strong enough—to ensure that they can safely control the bucket. A giant water-filled tub is certainly heavy enough to     10     injure or even kill a person it drops on.

Does the face-down    1    need a hands-up? Well, probably not. The fact is that many of today’s teenagers are better    2    and more creative than past generations. They also seem to be enthusiastic and    3    to become leaders. More young people than ever    4    to help their communities. There are also brave young people such as Malala Yousafzai, the teenager who won the 2014 Nobel Peace Prize for    5    girls’ rights to go to school.

Online, where posts can spread rapidly and everything leaves a trail, words can also be harsh. Often the only defence people have is     1    their online profiles entirely. But that means giving up a way to interact with others in a positive way. Bullying happens where young people spend their time-at present, mainly Weibo, Wechat, Hupu and Tieba. A widely suggested “solution” is to     2     teenagers to particular platforms. But then they will migrate to others.

Facebook and Instagram use artificial intelligence to spot verbal     3    . Most social-media sites have instructions on how to report     4     material and block other users. For example, Facebook this week announced new ways for users to avoid “unwanted, offensive or hurtful experiences”. However, a(n)     5     survey in Britain found that 70% of people thought that social-media companies do too little to prevent bullying.

More school-aged children have reported being cyberbullied than before the pandemic, according to the report     6    by the World Health Organization (WHO). The study surveyed more than 279,000 young people from 44 countries and regions. In Wales, where nearly 37,000 young people were surveyed, 17% reported falling     7    to cyberbullying. The Health Behaviour in School-aged Children (HBSC) survey suggests the proportion of adolescents who reported being cyberbullied has witnessed some     8     increases since 2018, from 12% to 15% for boys and 13% to 16% for girls.

Dr Hans Henri P. Kluge, a WHO     9    , said: “Focusing on virtual types of peer violence is now a priority to safeguard the health and     10     of populations of adolescents and young people, and cyberbullying must be viewed as a major issue for societies.”

Nowadays, there is widespread     1     over students’ loss of independence in study. In terms of academics, some students spend a     2     of time in study but fail to     3       to what they were expected. Over time, some even     4       under the pressure of study. Students who aim to be efficient and     5     learners should become more independent of their teachers. In high school, the change of the learning style is a     6     step toward success. For those who often     7     into a dreamworld of their own when faced with difficulties in study, teachers should guide them out of their comfort zone and help them     8     any pent-up (压抑的) feelings and find passion. As students practice independent learning, encourage them to     9       of changes. Scientific reports have     10     a connection between learning style and academic performance. Throughout learning process, students have     11       numerous situations which shape them who they are today and contribute to their personal growth.

Every small change in learning strategy has a(n)     12     -whether big or small-on students. The ability of     13     challenges     14     opportunities is a valuable skill that can     15     influence their learning career positively.

Raising a teenager today can be a challenging job. Long gone are the innocent     1     when you could have him accept your values or accomplish what you think the most important thing.

Today’s teens spend an average of 7.5 hours a day     2     to some type of electronic device and most know more about the Internet than their parents. This means they are potentially     3     to a lot more trouble than previous generation. It’s every parent’s first     4     to keep their children safe from harm or to rescue them before they     5     the consequences. Children need their parents to look after their welfare even if they are too     6     to understand and express that need.

However, protections such as parental control     7     can easily be turned off by skilful computer users. “Friending your child on Facebook doesn’t work     8    , either, as it offers users multiple ways to hide content from certain friends.

One of the best of these new services is TeenSafe.com. It’s an online service that allow parents to     9     their children’s mobile, social and Web activities, all in one place. The program can be easily customized for every family’s     10     needs to ensure that everything is okay online.
