Ian explained the ________ , “When we entered the trees, they were so ________ together that we each had to find our own paths.

4 . Recently, research on how a new virtual (虚拟的) reality (VR) experience educated primary children about the fire disasters was done. It was developed by the University of South Australia, aiming to educate children to learn how to be safer in a fire.

Focusing on children aged 10-12 years old, the new VR experience presents a situation where children are tasked to look after a friend’s dog just before a fire event begins to spread. They participate in a series of problem-solving activities to help save and protect themselves and the dog.

The findings showed that more than 80 percent of children reported that they felt more confident to calmly assess the situation and make wise decisions to protect themselves from a fire. This isl especially important considering that 91 percent of participants originally lacked any knowledge of fires, and that 67 percent had said that they were too young to make safety decisions in a fire.

The researchers believed such immersive (沉浸式的) VR experiences had real potential (潜力) to attract and educate the young. “As children born in digital times, they are interested in such technology and they can experience events realistically yet within the safe environment.” said Delene Weber, one of the researchers. “Well-designed VR can provide a chance for children to apply newly-acquired knowledge, strengthen their learnt concepts, and enable immediate reaction—all incredibly valuable learning tools.”

Meanwhile, because children have fewer life experiences, aren’t as physically strong, and are less likely to have learned much about fire safety, they’re often most at risk. Yet the ability for children to contribute to fire safety at their household should not be underestimated (低估).

“Children do not need to be passively attacked by disasters and with purpose-built virtual reality experiences such as these, we can help children understand the risks and realize they can help,” said Weber.

That summer I turned 18. I was wild with excitement because I just took my driving license and my parents bought me a new perfect car. I was reminded repeatedly by my parents to drive cautiously. Along with this new privilege (特权) came new responsibilities. I would practice the same routine-call my parents and tell them where I was going, whom I was with and when I would be home. It became a typical cycle.

I had been working all day in the hot sun.I was exhausted and ready for a nap. But my stomach told me something different. So I called my friend Mike and made our way into town. After our meal, we never knew our day would soon change for the worse.

It takes only a moment to turn your life upside down. I recalled later that I was driving fast. Actually too fast. I reached the conclusion two years later that the mistake would be with me for the rest of my life.

Mike and I were driving down a dusty gravel (沙砾) road. I was driving a shiny black Saturn,which was the car I had admired for long. I was overflowing with excitement and pride to be driving it.It was perfect in my eyes. I could see the rolling hills in the distance. Tall pine trees traveled on both sides of the road.The music playing loudly, we both were in high spirits. Somehow, without realizing it, I sped up.

Enjoying ourselves in my car,we came across a loose spot of gravel. My tires were stuck in it and desperate to escape. My car started fishtailing (摆尾行驶). Terrified,I pressed hard on the brakes and all of a sudden the car lost control. I froze, my body was stiff, great panic holding me entirely in its power. Looking into the right, I took a glimpse of Mike, whose body had leaned towards me. His face went pale but he was trying to balance himself. The car was rushing left to right, coasting (惯性滑行) along the gravel as if it were ice. It was only seconds later that my car crashed head on into a big pine tree.

8 . After an evening of overtime work with her colleagues at the office, Jill Bien, 48, boarded a bus bound for Chicago, where she lived. About 35 miles into the 90-mile trip, Jill felt the bus drive away onto the right shoulder(路肩)of 1-94．The bus scraped(擦挂)a concrete barrier，and then turned back into traffic.

“Stop the bus!” Jill yelled to the driver from her seat just behind him. But then she saw his seat was empty. The driver, James Rogers, 68, lay unconscious in the bus’s step.   “Call 911!”Jill screamed, and with the bus rushing in and out of traffic at about 60 mph in an uncontrollable way, she leaped into the driver’s seat and grabbed the wheel.

“My life flashed before my eyes,” Jill says now. “Everyone on the bus was bouncing around; they were lying in the aisle (过道).I thought, I don’t want anybody to get hurt.” Jill carefully turned the bus onto the shoulder, bringing it to a stop.

“Thank God she got that bus over to the side“ says Marge Borkowski, who was a passenger that night. “She’s my hero.” Emergency personnel arrived a few minutes later and took11 of the bus’s 34 passengers to the hospital, where doctors treated them for minor injuries. When Jill returned home after the accident, she burst out crying, she says. “I kept visualizing(眼前浮现)it.”

Despite anxiety and injuries, Jill boarded a bus back to the office two days later. “I didn’t want my fear to build up,” she said. Kenosha County policeman Dan Ruth, who was at the scene of the accident, told reporters he hadn’t witnessed an act more heroic than Jill’s in his 18 years on the job. “It could have been much, much worse,” he says.

9 . Peter, 60, loved his job as a bus driver. He had been one almost all his life, loving the little children who rode his bus daily. It made him feel much younger. His record was clean, without one accident, which made him a trustworthy driver.

However, Mr. Clark, Peter’s boss, was worried and thought that it was time for him to retire (退休). “You don’t have a choice here, Peter.” he said seriously. “We don’t want to invite any risk to the children.”

“But I have a perfect record,” reasoned Peter. “You know, for an elderly man like me, my job is the only thing that keeps me alive. I want to keep my job.”

“Would you take responsibility if something bad happened to those children?” Mr. Clark said.

Peter thought it over, and very reluctantly, he gave in to Mr. Clark’s request. Peter decided to retire a week later.

The day before his last day, Peter was dropping of the kids at his first stop when he looked out of the window and saw a lady who had passed out. He asked the kids not to leave the bus and got down to help the woman.

Just when he finished, he heard cries behind him. The children were looking out of the window and shouting. “Fire! Fire! Help!” “How could that have happened?” Peter was shaking in fear. With shaking hands, Peter dialed 911 and rushed to help the children. Covering himself with his jacket, Peter rushed into the burning car and took the children out one by one. Thankfully, the firefighters arrived soon and helped Peter, saving all students.

The next day, Peter found the whole school standing in front of his home. When Peter got close to them, Mr. Clark started clapping and everyone joined him. “You are a hero, Peter! You saved the lives of those young children.” he said. “You are the best driver. We hope you can keep the job!”
