1 . Being a teenager can be hard, for you have to face a lot of difficult problems, but a new program called Nfusion is working hard to help teens with mental(精神的)health needs. Nfusion gives teenagers classes where they study or discuss some troubling subjects. Drugs and bullying(欺凌)are just a few of the topics discussed during the class on Saturday.

"I had a bad attitude, " said 17-year-old Titeana Davis. Davis went through the Nfusion Program last year. The teen, who once had trouble with her attitude towards others, says the program has changed her life. "They taught me a bad attitude is not going to get you anywhere, "said Davis.

Nfusion is a new program that meets teens mental health needs and provides help for their families. The program is designed to help teens aged 14—21 live through a difficult period.

"They're still growing, still developing and still there are a lot of things they don't know how to address. So this is a good program for them to be a part of, " said Lakicha Jemigan, who worked for the Nfusion Program.

Teens like Davis are just a few who have come through the program successfully. Now thanks to Nfusion, Davis says she's looking forward to a bright future. "After I graduate from college, I want to work at a primary school and I want to be a second grade teacher, " added Davis.

2 . 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 family and friends. We use it to stay in touch with events we care about. The list goes on and on.

Well, that train has left the station.   This expression means there is no going back to an Internet-free life. But can using the Internet too much be bad for our health? It might be, researchers say. A new study finds that heavy Internet use may be connected to high blood pressure in an unlikely group: teenagers.

High blood pressure makes your heart and blood vessels work too hard. Over time, this extra pressure increases your risk of a heart attack. High blood pressure can also cause heart and kidney disease. It is also closely linked to a brain disease.

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 were described as “heavy Internet users.” And researchers found that out of these 134 teens,26 had high blood pressure. The researchers say the study is the first to connect heavy web use with high blood pressure. Other research has connected heavy Internet use with anxiety, depression and obesity.

The lead researcher is Andrea Cassidy Bushrow. She said, “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 take regular breaks from their computers or smartphones and do some kind of physical activity. She also suggests that parents limit their children’s use of the Internet to two hours a day, five days a week.
