2 . The COVID-19 has led to a great demand for bikes and biking. Bikes stores are struggling hard to keep up with the demand. In the United States, bike sales have seen their jump since the 1970s. Sales of adult bikes in April of 2020 were three times as high as last year. The situation is similar in Asia and Europe. Around 90% of the bikes sold in the US are made in China. But because of the COVID-19, even the normal supply of bicycles wasn’t being created. That demand began to go up in mid-March, as people began looking for ways of getting around that didn’t involve crowded public transportation. Because biking happens in the open air, and the chance of catching the disease while riding is very low.

Biking has also grown more popular because it is one of the few forms of exercise allowed in many lockdowns. With gyms and fitness shut down, biking fills a need for many active people. Families appreciate biking, too. With school closed and kids unable to hang out with their friends, biking is a welcome activity. Bikes are also practical. Many cities are seeing this as an opportunity to make their streets safer and greener. Cities around the world are adding mils and miles of bike lanes to their streets to encourage biking. New York says it will close off up to 160 kilometers of roads so they can be used by bikers and walkers. Paris has set up over 650 kilometers of new bike lanes. The United Kingdom plans to double its number of bike lanes. In Milan, Italy, 35 kilometers of roads have been metamorphosed.

Though many of these bike lane additions are temporary, and some people assume these additions seem to destroy the overall beauty of cities, if changes in biking habits become permanent because of additions, they could seriously cut down car traffic and help make cities a lot greener.

5 . Physical education, or PE, isn’t required for all high school students. In some schools, it isn’t offered for some different reasons. But should high school students have physical education? The answer is certainly “yes”.

Today many people don’t do sports. But as is known to all. doing sports is very important for an adult. Teaching teens the importance of a healthy lifestyle and making fitness plans now can help teens put exercise in the first place as an adult.

High school isn’t that easy. Many students are under a lot of stress. Stress can be harmful to a student’s studies and life. Doing sports can help them deal with stress better, helping them live a happier life at school.

The American Heart Association says that 10 million kids and teens suffer from obesity (肥胖). Teens should get 60 minutes of physical activity per day to control their weight and to help their bones get stronger. The increase in activities that don’t get teens to move around, such as computer games, means many teens don’t get their required exercise. PE classes act as a public health measure (措施) to encourage physical activities and help teens have healthy weights.

Not doing sports increases teens’ hazard of developing many diseases. An active lifestyle offers a good way of protection from these health problems. As much as 75 percent of health-care spending goes toward treating medical conditions that can be prevented by lifestyle changes, according to the American College of Sports Medicine.

According to the President’s Council on Fitness, Sports and Nutrition (PCFSN), students who performed five hours of physical activities each week improved their academic (学业的) performance. Students from programs with no physical activity, who used the extra time for classroom study, did not perform better on tests than those who gave up some study time in support of physical education.

6 . It was the 9th day of Wuhan lockdown (封锁) starting on January 23. My parents left because they had been running fever for several days and they were showing other symptoms of COVID-19.

The virus, COVID-19, is somehow fearsome because it does not discriminate (区别对待) in choosing who it infects. And if the older people were infected, the situation could be worse, so I was wondering whether my parents would make it.

On the second day, my parents called and asked me how I was. We talked using FaceTime, and the moment I saw my mom lying there with an oxygen mask and my dad could not talk without breathing heavily, I realized that I had to live on my own.

But two weeks later, I got a fever and had to go into quarantine (隔离) to be observed for 14 days. Fortunately, my illness turned out to be not COVID-19.

Everything there was busy, and there seemed to be a shortage of medical staff and materials were in short supply. Even though the doctors and nurses were covered from head to toe, I could see how tired they were when I looked into their bloodshot eyes. Most of the patients were really understanding, but of course there were those who were not, and complained loudly, but all the doctors and nurses tried their best to deal with it in a calming way.

When the quarantine was over, every patient thanked the workers for what they had done, but the answer patients received was exactly the same: “That’s what we’re here for.”

7 . As Wilson Guarin watched the helicopter flying above, he wondered if the men being lifted into the sky felt the risk had been worth it.

Moments earlier, Guarin and his children had hiked to Hermit Falls in Angeles National Forest, one of the most popular waterfalls in the Los Angeles area. Soon after they arrived, they saw a man injure his shoulder when he jumped into the rock pool at the base of Hermit Falls. Less than a minute later, another man jumped and appeared to break both his legs. Guarin said the cliff jumpers' purposes were obvious. They wanted to get a video of themselves and post it to social media.

A thirst among hikers, often inexperienced and under-prepared, to collect "likes" and shares on Instagram and other social media sites has led to a sharp increase in rescue missions by first responders.

The Los Angeles County Sheriff's Department's Search and Rescue teams conducted 681 missions in 2017, the largest number in five years. It's a 38% increase from the 491 rescues they did in 2013.

The teams' leaders say the single largest factor for that increase is people posting videos of extreme activities online. Then, without any thought about the difficulty, others try to recreate their own 15-second version of glory.

On Instagram, posts from visitors making adventures in waterfalls and swimming holes in Angeles National Forest and other recreation areas show hikers changed into models, striking seemingly the same poses in the same places.

We shouldn't prevent people from enjoying the outdoors. But many accidents are avoidable and happen either when people go off trail or ignore official warnings about an area being closed and visit anyway.

Guarin still thinks about the two men he watched in helicopter rides sent to a hospital. "You get concerned about what people are willing to do—to not have fun. It's risking everything for no reason.

Well, there are the "likes".
