Central Park is New York's largest city park and one of the biggest in the world, with an area of 843 acres.This park is home to man-made lakes, waterfalls, grass and wooded areas.You will also find the Central Park Zoo, among other attractions in this green space of New York.

Besides, being the city's primary green lungs, Central Park is also a favorite spot for many New Yorkers. It is perfect for sunbathing, going for walks, or doing any outdoor sports. Something that we found curious is seeing so many people running with their babies in prams.

To get to know some of the wildest parts of Central Park, we suggest walking.However, to get a general feel for the whole park, the best thing to do is to hire a bicycle and enjoy the scenery.If you decide to hire a bike, you will find lots of bike rental stores around Central Park that are not very expensive.

In the past 70 years, physical activity in America has transformed from a necessity of daily life into an often-expensive leisure(闲暇)activity, and has reformed itself as the basis of people's social position."In the 1950s and 1960s, the body became a problem, and exercise developed — it had to develop-because people realized that we were all going to die of heart attacks," Shelly McKenzie, the author of Getting Physical： The Rise of Fitness Culture in America, told me.

With new middle-class needs coming into new marketing, Jack LaLanne^!s instructional exercise TV show introduced much of the country to the active pursuit of physical fitness in 1951, paving the way for workout tapes from fitness superstars such as Richard Simmons and Jane Fonda.In the 1970s, exercise began to leave the home, both through the popularization of jogging and weightlifting and in more organized ways, such as Jazzercise classes.

No matter how they package it, these businesses aren't just selling physical activity； they're providing people with a way to stick to expectations that the industry itself helped set."Exercise, and especially public exercise, came to indicate mental, emotional, and even spiritual health and virtue," Marc Stern wrote in 2008," In return for the effort, gym-goers attain(获得)the type of body that proves their virtue to all who see them.”

That these physical standards are difficult to achieve is the point."We live in a culture in which being diligent is highly, highly praised," Petrzela, the New School professor, who is working on a book about fitness's place in American culture, told me.

“Many people want to be regarded as people who value exercise, because it shows they're committed to（致力于）self-improvement, and to hard work."Above and beyond movement itself, part of the satisfaction of gym-going comes from performing those values around other people who share them, and from achieving what that community regards as success.

On the outside, 12-year-old Luna seems like an average kid.It's not until you get to know her that you learn that Luna is anything but average.

Born with a heart defect （缺陷）called dextrocardia, Luna has had three open-heart operations and continues to pursue（追求）her interests in art and fashion.But when Luna was approached by athletic shoe company Saucony to design a shoe for sale across the country, it came as quite a surprise.

“This is so incredible.I got to use my art and creativity for something new that I'd never thought I'd be able to design,“ Luna said.She is one of six patients from Boston Children's Hospital （BCH） who have partnered with Saucony to design their own shoes to launch the Shoes with Soul campaign.

“Rather than just a donation, we wanted to create an experience and a moment that would raise not only money, but also awareness to highlight all the amazing work that's being done at BCH," says Chris, Saucony's vice president."Specifically, we wanted to give some of the BCH kids an opportunity to share their stories and their talents with the world.”

Luna's design is fashion."On the tongue, they digitalized（使数字化）one of my drawings, and then on bottom it's a really bright pink color, and on the inside, the sole of the shoe is actually another drawing I did of a sunset," she said."Thinking about kids everywhere around the world wearing my shoes is amazing.It blows my mind.”

The income from the shoe sales will benefit the Boston Children's Hospital Cardiac Fitness Program, which encourages kids to ''find your possible" through personalized exercise programs tailored for each individual patient's heart condition.

“It feels really good to help people and it's really something I can relate to," says Luna."The advice I would give a kid or someone like me is never giving up.There are a lot of kids out there with your condition and you're not alone.

There's plenty of video evidence on social media about some urban wildlife during pandemic lockdown（疫情封锁）.And while it's been for tragic, costly reasons, we have to stop the human activity all over the world for a while.

On an increasingly crowded planet, wildlife scientists think that this will have some important effects.The only way to measure that, though, is with lots of bio-loggers.

Professor Christian Rutz, University of St Andrews said that a bio-logger is a small electronic device that can record, store and in some cases automatically send information, so that information could be positional information, from which we can find out through satellite（卫星） tracking where an animal goes and what it's up to.

Through using the labor-saving equipment, researchers can get much information.For example, the information about more than 1500 birds' movements and migrations （迁徙）was recorded by those bio-loggers over a decade effortlessly.

However, studying human absence is more     tricky."One famous study in the Chernobyl exclusion zone that I visited with scientists last year, has shown how nature took over a landscape that was abandoned after the nuclear disaster." Professor Christian Rutz said.

Now, in dozens of ongoing studies, wildlife researchers have their bio-loggers on animals from African elephants to migrating birds, and some of that data has been automatically uploaded throughout lockdown.Scientists do the research by focusing on the behaviour of animals without the presence of human.

Professor Christian Rutz told BBC： "And so this is really a golden opportunity to research this relationship between humans and wildlife and we hope that this project will inspire us to make plans for the future and there are some very useful suggestions that could come out of this.”

This lockdown has been at huge human and economic cost, which is why scientists say it's important to maximize what we can learn from lockdown, about how to share the space we have with many other animals.
