My hands were shaking uncontrollably. I tried incredibly hard to focus on the words that I spent hours putting down on paper. I tried to defeat my fear of speaking in public on numerous occasions throughout my life. During college and at my first few jobs, I would get ridiculously nervous when I had to give a presentation or lead a meeting. Public speaking had been my nemesis for as long as I could remember.
Then in my mid-thirties, I decided to join the public speaking group Toastmasters. At every meeting we were rated and forced to compete with other speakers for an award. You would think that I would walk away from these experiences as a polished speaker, but nothing seemed to work.
It wasn't until recently, when science and scientific institutions were being attacked for unfair reasons during the pandemic, that I decided I must speak out. Science has made this country a place where dreams come true -this is why we all need to protect science. In addition, as a science writer, I try to get readers to understand how science is related to their daily lives.
So I was on that frightening stage on that sunny Saturday in April-Earth Day. Despite the body shakes and fear, I persevered. That day, I looked out into the crowd of like-minded science supporters and I felt comfort.
Reaching that milestone goal of getting through a speech truly changed me. At almost forty, I learned that passion can set off a flame in my heart to do things I never dreamed possible. The darkness that led to my speech is sure to lead to new opportunities and adventures.
Scientists researching climate change in Antarctica are studying penguins in an effort to better understand the area's environmental health. The scientists are measuring the growth and development of the penguin population on the eastern side of the Antarctic Peninsula. "We are counting penguin nests to understand how many penguins are in a colony, producing young every year, and whether that number is going up or down with the environmental conditions, " said Alex Borowitz. He is an ecology researcher at New York's Stony Brook University.
The work is not easy for climate researchers in the icy, faraway reaches of Antarctica. But penguins are easier to follow than some other kinds of animals because they nest on land. Their black bodies and waste droppings can also be identified against the area's white background.
Michael Wethington, another researcher from Stony Brook, told Reuters the penguin population can represent overall climate conditions and the health of the area's whole ecosystem. The researchers say counts of individual penguins can be combined with data from satellite images to get a more complete picture of how the animals are progressing.
Gentoo penguins-with bright orange beaks and white markings on their heads - prefer open water without broken pieces of ice floating around. So when temperatures on the Antarctic Peninsula began rising during the latter half of the 20th century, Gentoo populations moved south. Gentoo penguins don't like sea ice. They mostly forage (觅食) over the continental shelf and don't go far out to sea. As sea ice has decreased along the western side of the peninsula, Gentoos seem to have gotten used to the changed conditions. But those same conditions have been worse for the Adelie penguin species. This is because the Adelies depend on sea ice for feeding and reproduction.
"When we find Adelie penguins, we typically know that sea ice is nearby, " Stony Brook's Wethington said. He added that whenever researchers see sea ice decreasing or disappearing, they also see Adelie penguin populations plunge. Even though Adelie penguins are increasing in number overall, some populations have fallen by more than 65 percent, researchers say.
Virtual reality is quickly becoming the new technological frontier. Tech companies everywhere seem to be racing to get their foot in the VR door. However, Virtual reality has a set of challenges and hurdles that it must overcome in order to work well. It should be noted that VR is heavily dependent on being very fast, very accurate and very good-looking. If it isn't, the viewer will feel motion sick or disconnected from the world that VR is trying to create.
Now that we can actually build VR headsets that begin to meet these requirements, we are seeing a rising interest in VR. As it rises, so does the interest in creating new media to be experienced in using virtual reality. Journalism is a medium built on relevance. Journalists should always be finding new ways to tell stories and deliver content. It is a goldmine for storytelling. What better ways to tell a story to someone than to put them right in the center of it?
Virtual reality is a powerful tool for journalists. The consumer isn't just reading or watching something play out; they're experiencing it. The immersive nature of VR allows for people to connect with the subject matter on a much deeper level than just reading about it. The experience is emotional, speaking more to our instinct than our intellect. The possibilities for storytelling here are legion, and any storyteller wanting to do something more interesting than their peers should surely be considering the sheer power of VR.
The question of virtual reality, though, is not how powerful it is. That is immediately apparent. The question of VR is one of viability and availability. Telling stories must be easy to do, and access to those stories must be readily available. This is the biggest challenge that VR faces. If the tools to tell a story with VR. aren't easy to pick up and learn, VR will fail. If VR technology isn't both top-of-the-line and affordable, VR will fail.
Accessibility was one concern for Thomas Hallaq, assistant professor of journalism and mass communications, who said that current VR technology, is pretty exclusive right now. Despite that, he said he doesn't think the exclusivity of this technology will be a problem in the long run.
"I think it's very promising, " Hallaq said. "We're seeing more technology become accessible, and more people having access to that technology. Just look at smartphones." Like radio, TV and the Internet before it, virtual reality will change the way we tell stories.
More people get off the beaten track for relaxing break
Going against the tide of flocking to well-known yet generally jam-packed tourist destinations on vacation, a growing number of holidaymakers in China tend to spend their leisure time at lesser-known resorts to seek unique, relaxed holiday experiences.
That is what Dai Bin, president of the China Tourism Academy said. He said popular tourist spots are always packed and often raise their prices during holidays. As people become more mature travelers, they are increasingly reluctant to follow the herd. And it is a good way to vacation. According to data from online travel agencies, the number of rooms booked at hotels in less-traveled cities during the holiday was up 30 percent year-on-year. In addition, lesser-known attractions are not as "commercial" and "standardized" as developed ones and are able to offer more authentic experiences and natural encounters, according to social media posts.
COVID-19 is another key factor fueling reverse tourism. As precautionary measures continue, traveling has an unpredictable quality. Travelers have no way of knowing what lies ahead before departure, be it a perfect holiday or one interrupted by a sudden outbreak.
The rise of reverse tourism is not a bad thing. It means that vacationers now have more options, which brings more possibilities to the tourism market.
A. The trend is set to force popular destinations to improve themselves.
B. Tourism used to be about sightseeing but now it is about experiences.
C. Some of them are simply looking to take a rest somewhere quiet for a couple of days.
D. Reverse tourism has emerged as a new, trend, especially among young holidaymakers in China.
E. During the week-long public holiday, large numbers of vacationers long to escape their busy city life.
F. They have thus become more cautious and tend to choose local attractions or places with fewer tourists.
G. And unlike popular destinations, some under-explored places with little online exposure can offer more surprises.
In colleges around the country, most students are also workers.
The reality of college can be pretty different from the1 presented in movies and television. Instead of the students who wake up late, party all the time, and study only before exams, many colleges are full of students with2schedules of not just classes and activities, but real3too.
This isn't a(n)4phenomenon. The share of working students has been on the rise since the 1970s, and one-fifth of students work year round. The 5 can help pay for tuition and living costs, obviously. And there's value in it 6the direct cause: such jobs can also be7for developing important professional and social skills that make it easier to8a job after graduation.

But it's not all upside. Even full-time work may not completely.11the cost of tuition and living expenses at many colleges.

And working full-time cut into the time14 for studying and attending classes. Students who15leaving school because of difficulty in managing work and class are likely to find themselves stuck in some of the same jobs they might have gotten if they hadn't gone to college at all.

Counting the votes took about five minutes, but it seemed like hours. At last, after three long years，the "PCHS" letters on my uniform would soon be edged with gold cording (金线), identifying me as the important Captain of Polk County High School cheerleaders, which was quite an accomplishment before I ended my school days in a blaze of glory.
"Girls, " she began, "it is my pleasure to announce that Terry Shaw has been elected Captain of Polk County High School cheerleading team." A resounding cheer was heard throughout the gym. How could this be? I hadn't missed a practice or a game in three years. Terry couldn't claim this flawless record.
Everyone gathered around Terry with congratulations, but I was glued to my seat that only moments before was the springboard to my throne (宝座). She had stolen my thunder and swept my dream right out from under me. Finally, I walked over to Terry on shaky legs and managed a "Good luck, Terry, " in a whisper that barely masked my urge to cry. Terry hugged me close and said, "I wasn't expecting this, Annie. What a shock." I didn't reply to her with mean words but deep inside I wanted to do just that.
All the way home, I sobbed. There was no way I was going to stay on a team so blind that they couldn't see the one most deserving of being named captain. I slammed the front door, stomped up the steps and threw myself onto my bed in a dramatic display of sobs and sighs that eventually gave way to sleep.
The next morning, I marched over to my closet and took out my uniform. Once it was in my hands and I held it close to me, I knew I couldn't quit. Heartbroken as I was, my true love was cheering with my teammates.
How hard it was to go to that first practice after Terry had been named captain. The moment I arrived, Coach Maguire asked me to take three of the new girls and work with them on our basic practice. Terry was assigned three as well.
