In modern age     1     the Internet becomes an irreplaceable part of our daily life, people spend too much time on phones. We     2     (engage) in reading new messages, answering emails, as well as     3     (scroll) through social apps all the time, even when having a shower.

It seems that the Internet brings people closer to each other.     4    , it brings more depression and     5     (lonely) on people. On the one hand, social networking online has dominated most of our spare time, causing us     6     (delay) finishing the normal tasks and jobs. Day after day, we will experience     7     strong sense of dissatisfaction and depression from work. On the other hand, in a real face-to-face communication, we are often interrupted by the never-ending flow of updates in our phones, thus making others uncomfortable. It is not strange that we are bending over the phone, with our eyes     8     (fix) on the screen.

    9     (consequent), it is high time that we     10     (lift) our heads before we are too addicted to phones.

Recent literature has put the spotlight on how technology and social media are shaping the next generation, and the consensus(共识)seems to be that it’s a sharp double-edged sword. New research published in Computers in Human Behavior is no exception.The study,led by faculty at Wellesley Centers for Women, found that     1     (join)social media specifically, Snapchat and Instagram before age 11 was significantly linked to more “problematic digital behaviors”     2     (compare) to those who joined the platforms when they were older.

The team surveyed over 750 middle schoolers in the Northeast United States, and found that those who joined these platforms at or below age 10 had more internet buddies that parents would disapprove of, and visited more social websites that     3     (frown) upon.They also showed more “unsympathetic online behaviors” and were more likely to become victims of online bullying or harassment. Altogether, it was a jumble of (一堆)problematic digital moods. Of course,that might not be news to social media giant Facebook. Some recent leaks in the Wall Street Journal revealed how the platform was aware for some time     4     it was “toxic” for teen girls, and also detailed its ambitions to lure teens and pre-teens with targeted kid-specific products.     5     almost all social media, including Twitter and TikTok, Facebook’s rules require users to be at least 13 years old to join. However, people     6     sign up self-report their own dates of birth, so it's hardly an effective firewall, and by commonsense, it's nearly a given that packs of children are roaming(漫游)the social media universe. In fact, “one-third of our sample had already started using social media at age 11 or 12 and another one-third had begun at age 10 or younger,” study author Linda Charmaraman said in a statement.     7     that doesn't mean it’s a lost cause. The study's findings also suggest parents can combat the harmful impacts by limiting how often their kids check social media, or restricting phone usage. Participants who reported such parental controls showed     8     (lessen) negative effects.

And it's not all bad: According to the research, those who joined social media before age 11also showed     9     (great) civic engagement within the online community--such as posting supportive content or fostering events and activism for social issues. Also,regardless of when they joined social media, early adolescents displayed more positive digital behaviors overall than negative ones.

As the first children raised in the social-media era grow into their 20s and 30s,the effects of the internet revolution will likely become more profound, and we can expect that the need     10     (understand) how tech shapes kids in their most impressionable years will only become more urgent.

It's estimated that two-thirds of people online have had their personal information     1    (steal).

Faced with such a range of     2    (threat), it's easy to focus on technology investment. Firewalls, anti-virus protection and every other kind of technology can be threatened as well. That's not to say that     3    (invest) in IT security isn't important. But the cybersecurity (网络安全) threat needs individuals     4    have skills, talent and experience     5    (bad). Indeed, there will be a global shortfall of 3. 5 million cybersecurity jobs by 2021.

Only with people power can we win the online security war. Here     6    (be) the main reasons and methods.

First of all, it is important to improve the security     7    (aware). Security is becoming important, with organizations starting to understand the big role that individual employees must play.

Secondly, pay attention     8    grassroots education. As we face a significant skill shortage in the future,    9    is of great importance that together we help create the next generation of cyber defenders now.

Thirdly, encouraging skilled staff also matters. Most organizations have concerns about security skills, and two-thirds have trouble     10    (encourage) the security staff they have.

We can achieve almost anything online - with access     1     the Internet come some truly life-changing advantages.

One of the     2     (great) advantages lies in the huge amount of information. In the time it takes     3     (find) one book in the library, with the click of a mouse,     4     is possible to find out almost anything we care to know. No wonder the Internet has now become the first place     5    the majority of people find information.

Since it     6     (invent), the Internet has made our lives unbelievably convenient, with all sorts of goods and services provided by e-commerce. You can have food delivered to you     7    (use) food delivery apps and sites. You can pay for almost everything on your smartphone.

However,     8     the Internet brings many valuable advantages, being connected has its problems. As with any great invention, we must be aware of these problems and be careful to use the Internet     9     (proper). Only in this way can the Internet be a place of     10    (discover), wonder and inspiration for everyone. It is truly a world without frontiers.
