2 . As 17-year-old Torri’ell Norwood drove through Florida, last February, the laughter and chatter from the four teenage girls inside her car quickly gave way to screams. As they approached an intersection, another car T-boned them, sending their car sailing into the yard of a nearby home, coming to a stop only when it crashed into a tree.

As smoke rose from the car, a bystander shouted, “It’s about to blow up! Get out!” Shaken, but otherwise OK, Norwood crawled out through the window as the driver’s side door couldn’t be opened. Along with two of her friends, who’d also managed to free themselves, she ran for her life. But halfway down the street, she realized that her best friend, Simmons, wasn’t with them. Norwood ran back and found Simmons unconscious in the back seat. She threw open the back door and pulled her friend out. She dragged Simmons a few feet to safety and laid her on the ground. After checking her pulse and found there was no sign of life, she started CPR.

Had the accident happened a few weeks earlier, she might not have known what to do. But just the day before, Norwood, who wanted to pursue a career in medicine, had earned her CPR certificate by learning on her own. Kneeling on the lawn and looking down at her dying friend, Norwood knew she had precious little time to practice what she’d learned.

She started pumping Simmons’s chest with her interlocked fingers and breathing into her friend's mouth in hopes of filling her lungs with the kiss of life. After quite a while, Simmons began coughing and taking quick deep breaths for air. The CPR had worked! Soon, the ambulance arrived and rushed Simmons to the hospital. And then she heard how her best friend had saved her life. “I wasn't shocked,” Simmons told others. “She will always help any way she can.”

3 . As 17-year-old Norwood drove through St. Petersburg, Florida, last February, the laughter and chatter from the four teenage girls inside her car quickly gave way to sharp cries. A car behind heavily hit them, sending their black car into a tree five meters away. As smoke rose from the other car, a bystander (旁观者) shouted, “It’s about to blow up! Get out!”

Terrified but not hurt, she got out through the window. Along with two of her friends, who’d also managed to free themselves, she ran for her life. But halfway down the street, she realized that her best friend, Simmons, wasn’t with them. Norwood ran back and found Simmons stuck in the back seat. “She wasn’t moving,” Norwood told Inside Edition. She threw open the back door and pulled her friend out, trying to avoid the broken glass.

She dragged Simmons to safety and placed her on the ground. “I put my head against her chest. No sign of life. That’s when I started CPR (心肺复苏术).” Norwood, who longed to have a career in medicine, had passed the national CPR test just the day before.

Looking down at her dying friend, Norwood knew she had only a little time to practice what she’d learned. She started pumping Simmons’s chest and breathing into her friend’s mouth. No response. She tried again and again. Slowly, Simmons began coughing and opening her mouth for air. The CPR worked! Soon, doctors arrived and rushed Simmons to the hospital. And then she heard how her best friend had saved her life. “I wasn’t shocked,” Simmons told CNN. “She will always help any way she can.”

4 . Should people be allowed to use cell phones while driving? People have different opinions about it.

No, because in this world some people drive very crazily. So most people who use cell phones to talk in the car usually pay more attention to what they are talking about than to driving. One of the reasons that I feel this way is that my friend had a car accident while using a cell phone. He lost his life and his friends did, too.

——Alejandra Pachecho from Venezuela

That depends. The advantages of using a cell phone while driving are that you can call the police if there is a car accident, and call for help when somebody’s car breaks down. The disadvantage is that people get distracted (思想不集中) when they are driving at the same time they are talking on a cell phone. It can cause car accidents.

——Rodrigo Cruz from Colombia

Yes, if they use it correctly. Sometimes drivers are very dangerous when they are talking on a cell phone. They may not drive well if they use one hand to hold the phone and the other hand to drive. In this case, drivers should use a hand-free accessory to talk while driving. That is a safe way to use them while driving.

——Pantium Wong from Hong Kong

No. Cell phones are extremely popular among teenagers. One problem is that they talk on them while they’re driving. Sometimes some of them aren’t careful and drive too fast. Talking on a cell phone while driving at high speed is very dangerous. They shouldn’t drive and talk on the phone at the same time because they can’t control the car and may cause accidents.
