Nowadays, one of the common     1     (phenomenon) is to see ordinary people listening to music with headphones,     2     (absorb) themselves in their own world. Moreover, people often share     3     (satisfy) records with their friends. In     4     (add), we can gain relief from pressure in the deepest part of our being.

    5     is proved that music can be used as a cure     6     diseases. Listening to positive and peaceful music will have     7     positive impact on people, which enables many patients     8     (reduce) pain. Classical music has reached a stage     9     it is often used in cancer treatment     10     the aim of relieving aches and side effects.

Today I thought I’d blog about a question     1     has been asked many times—how do you stay safe online and avoid bad     2     (experience) on the Internet? I’m not an expert, but many years as a     3     (blog) have taught me a thing or two.

First     4     all, there’s the golden rule of the Internet: If you see or read something     5     makes you feel uncomfortable, leave the site     6     (immediate). Don’t post     7     (comment) or click     8     anything. Second, protect your privacy. Don’t give     9     your address or phone number. Someone might use the information     10     (steal) your identity. Identity theft is a common and serious problem. Third, be polite.     11     (be) online is no excuse for     12     (be) rude, and you don’t want to become     13     target for a troll or cyberbully. A troll is a person     14     posts comments or questions in order to stir     15     trouble online. Trolls often use several false names so that they can stay on a site. A cyberbully uses the Internet to be mean     16     others. Like a troll, a cyberbully will also write something mean but it is usually directed     17     particular people. He or she may also post     18     (embarrass) photos and information about those people. However, the more polite you are, the less likely     19     is you will be attacked.

Have you had any bad     20     (experience) online, or do you have some good advice for     21     (stay) safe? Post your comments below!

Boy 579: Last year, we were having     22     (problem) in our chat room. Mean     23     (comment) were being posted by someone we didn’t know. I think he or she was only trying     24     (make) trouble.

Amy: A girl at my school had a very bad experience online. A photo of her had been posted online and she was being made fun     25    . It seemed like a joke at first,     26     the girl was very upset.

4 . The Internet plays a big part in human life. We use it for work and pleasure. We use it to learn a new language. We find advice on it. We use it to connect with our family and friends. We use it to stay in touch with events we care about. The list gods on and on.

As far as the Internet being a part of our lives — well, that train has left the station — there is no possibility of going back to an Internet-free life. But can using the Internet too much be bad for our health? It might be, say researchers. A new study finds that heavy Internet use may be connected with high blood pressure (血压)in a young group: teenagers.

The study results show that tens who spend at least 14 hours a week only online may cause high blood pressure, which makes your heart and blood vessels(血管) work too hard. Over time, this extra pressure increased your risk of a heart attack. High blood pressure can also cause other diseases.

The Henry Ford Hospital in Detroit, Michigan did the study. 335 young people, from 14 to 17 years old, took part in it. 134 of the teens are described as “heavy Internet users” And researchers find that out of these 134 tens, 26 have high blood pressure. The rescarchers say the study is the first to connect heavy web use with high blood pressure.

The lead researcher is Andrea Cassidy-Bushrow. She says, “Using the Internet is part of our daily life, but it shouldn't ruin us.” Ms Cassidy-Bushrow adds that it is important for teens to stop to have a rest regularly from their computers or smartphones and do some kinds of physical activities. She also suggests that parents shouldn't let their children use the Internet for more than two hours a day, five days a week.

When you are surfing the Internet, you can be anyone or anything. Avatars are a key part while people use the Internet to communicate. and express themselves. The first simple 2D avatars     1    (appear)in role-playing computer games in     2    1980s. Nowadays, avatars are everywhere and people can choose an avatar from a selection of images     3    (make) by others or create their own ones. You can also use avatars that move around and talk while     4    (type) in your message. The avatar that you choose says a lot about your personality. Most people create avatars that have similar features to their personalities and that look more or less like them. People     5    (obvious) make a few improvements to their avatars to make them look nice. Avatars not only let you express yourself but also give you much room for creativity. But the use of avatars has also caused a few     6    (concern). Some users worry that they are spending so much time in virtual worlds     7     they are becoming afraid of meeting people in the real world. Others worry that some people can use avatars     8    (cheat) online. However, there are some people     9    (view) avatars in a more positive light. They look forward to a time     10     their avatar will act like a real person.

10 . Psychological science is full of interesting topics, many of which tell a coherent picture of human nature, but some of which create seemingly contradictory stories. A case in point is the misunderstood overlap(交叠) between strength­based science and the research on narcissism (自恋).

There is now convincing evidence to show that narcissism is on the rise, especially in our youth. Some researchers say that about 25% of young people showing symptoms of narcissism.

We are correct to be concerned about this phenomenon, but our fear that all kids are potential narcissists has caused an unhelpful reaction against approaches that seek to make our children and teens feel good about themselves.

In my own research on strength­based parenting, it is common for people to wrongly think this approach to be the cause of narcissism. Their argument seems to be that a child who knows their strengths will automatically view themselves as better than everyone else. It is argued that the self­assurance that comes with identifying and using their positive qualities will make a child selfish and uncaring.

Why does this occur? It’s partly because more is known about narcissism than strengths. While strengths psychology has largely stayed within the limit of academic journals, research on narcissism has made its way into the mass media and our daily life.The New York Times noted that narcissism is a favored topic and that people everywhere are diagnosing others with it.

The fear that a strength­based approach will cause narcissism also occurs because of our binary (非此即彼的) thinking. We mistakenly believe that one cannot be both confident and humble. Without confidence in their strengths, Gandhi and Mother Teresa couldn’t have achieved so much, and yet modesty and selflessness are their qualities.

When we assume that strength­focus is the same as self­focus, we fail to make the idea clear that people who know their strengths are, actually, more likely to be pro­social and ready to help others.

It’s easy to conclude that every young person is at risk of becoming a narcissist but I’d like to stand up for the thousands of young kids I have worked with who are caring, thoughtful and humble—even when they use their strengths.
