1 . It’s difficult to determine whether social media is safe enough for children’s mental health, according to a new report from Dr. Vivek Murthy.

Although there are some benefits, social media use brings “a great risk of harm” to kids. “We’re in the middle of a youth mental health crisis, and I’m concerned that technology companies are contributing to it,” Dr. Murthy said.

“It is generally believed that parents and kids should be responsible for managing social media, despite the fact that these platforms are designed to increase the amount of time that our kids spend on them,” he said. “So that is not a fair fight. It’s time for us to support parents and kids.”

Up to 95% of kids aged 13 to 17 report using social media, with more than a third saying they use it “frequently”. And although 13 is commonly the minimum(最小的) age to use social media sites in the US, the report notes that nearly 40% of kids aged 8 to 12 use the platforms, as well.

One study of 6,595 US adolescents between ages 12 and 15 found that those who spent more than three hours a day on social media had twice the risk of symptoms(症状) of depression and anxiety as non-users, the report notes. It also cites(引用) studies that found reducing social media use led to improvements in mental health.

Murthy says he hopes the report will encourage measures before it is too late. “Independent researchers tell us that they have a hard time getting the information they need from technology companies about the health effects on kids,” he said. “Social media companies should be responsible for protecting children as other industries are. As to other products that kids use, we take the approach of safety first. We need to do it here, too.”

2 . Cyber-bullying (网络欺凌) may take place in the online world, but it is no less damaging than in the real world. The Internet has become a kindness desert, a place where few flowers bloom. Bullying is pretty common.     1     According to those bullied, they’re usually seen as being different from the crowd. They are unique.

Being bullied is a frustrating and painful experience. Online bullying can really hurt others, and it can have serious consequences.     2     Some people have even committed suicide because they were harassed (侵扰) online and didn’t think it would ever stop. Here are some valuable tips to help you address a bully and protect yourself in a safe way.

Don’t blame yourself.     3     It’s only the bully’s fault, so don’t blame yourself for his or her shortcomings.

Stay away from bullies. Bullies hope you interact with them so that they have an excuse to keep picking on you. When the bully starts orally attacking you, remove yourself from the situation if you can, simply by walking away.

    4     Try as you might to ignore the bullies when they are saying ugly things about you. Remind yourself that you are a great person and that nothing the bullies say matters.

Speak out. Nobody has the right to make you feel unsafe, uncomfortable or unhappy. Find someone you can talk to, your teacher or your parent and tell them what’s going on.     5     Follow these tips and you should feel well-equipped to deal with your bullies the next time they attack.

A．Keep track of bullies.

B．Be sure you’re wonderful.

C．Adults can offer help if they know about the problem.

D．Being bullied can make you feel alone, scared, and hopeless.

3 . The current generation is not like any other generation I have seen in history. Due to the rise in technology, the world is evolving fast and changing the way most of us do things. Today’s young generation is so used to the technology which they learn very quickly. It could be considered as a benediction, but there are times when it is not appropriate.

In my generation, we met friends face to face to have real conversations rather than texting each other all the time. We walked everywhere, to the store or up the stairs instead of climbing into our car or on a motored skateboard each time we had to go two or three blocks away.

Most of the new generation expects things to be done for them. If something requires some extra effort or focus, they are easily discouraged. But if we want to reach success in this day and age, it is expected of us to work to achieve our dreams. The old generation knows that the world does not owe them squat. It understands that no one else than them can do it and that is their responsibility to make something of themselves.

Nowadays, there is no longer a sense of honor, because most people hide behind a computer screen. When you handle issues or hate for no reason over social media, it just proves that you are a weak person. I just put an ad in one of my groups for teaching Kung Fu, and one hater wrote “Kung Fu clown.” And this is for no reason as I have never seen or met the guy before.

The new generation relies too much on social media for their lives and doing things. It is okay to use it but not to abuse it. My final word is that each generation has its own advantages and downsides, but what matters is that each generation, old or new, has to give lessons which are valuable for future generations.

4 . Thousands of people now use computers for many different things.     1     But have they?

Of course computers are great in that they have improved some people’s lives for the better. However, they also cause problems, too. A large number of people who use computers a lot can get physical problems.     2    . There will be injures in computers users’ hands and arms, as people use the keyboard and the mouse too much. People who have computers are also spending more time sitting down and less time exercising; so many of them are becoming overweight.

    3     One example is stress. Computers, the Internet and email have made many people’s lives much faster. This can be very exciting, but it also means that people feel under a lot of pressure to do everything more quickly, which is stressful.

Addiction is also a problem with more young people. They can spend hours and hours in chat rooms and surfing the net. Sometimes until very late night.     4    .

Some studies in the unites states have suggested that young children and teenagers who spend many hours at computers tend to get lonely and even depressed.

“    5     But parents and teachers used to help children to learn to use computers in responsible and creative ways.” says teacher Jane Shields. “And children should also learn when it is time to log off the computers and head outside to do something different.”

C．We should have a right attitudes towards the computers.
