2 . If history doesn't quite repeat itself, it certainly rhymes. With demand for bicycles rocketing, and nations preparing to spend billions of dollars to redesign their cities with a new focus on cycling and walking, it's worth remembering how the invention of the bicycle in the late 19th century transformed societies the world over. It was a hugely revolutionary technology, easily equal to the smartphone today. For a few heady years in the 1890s, the bicycle was the best must-have—swift, affordable, stylish transportation that could take you anywhere you cared to go, anytime you liked, for free.

Almost anyone could learn to ride, and almost everyone did. The sultan of Zanzibar（a former Muslim country）took up cycling. So did the king of Russia. But it was the middle and working classes around the globe that truly made the bicycle their own. For the first time in history, the masses were mobile, able to come and go as they pleased. No more need for expensive horses and carriages.

Society was transformed. Women were especially enthusiastic, abandoning their burden some Victorian skirts, adopting reasonable clothes, and taking to the road in groups. “I think bicycling has done more to liberate women than anything else in the world,” Susan B. Anthony, the American champion of women's suffrage（选举权）said in an interview with The New York Sunday World in 1896. “I stand and feel thrilled every time I see a woman ride by on a wheel...the picture of unrestricted womanhood.”

By 1898 cycling had become such a popular activity in the United States that The New York Journal of Commerce claimed it was costing restaurants and theaters more than $ 100 million a year in lost business. Bicycle manufacturing became one of America's biggest and most advanced industries. A third of all patent applications were bicycle-related—so many that the US patent office had to build a separate building to deal with them all.

The arrival of the bicycle touched virtually every aspect of life—art, music, literature, fashion, and even the human gene pool. English songwriter Henry Dacre scored a huge hit on both sides of the Atlantic in 1892 with Daisy Bell and its famous refrain（副歌）A Bicycle Built for Two.

3 . Want to know what we can do to help make our city a better place to live in? Why not take part in “Clean & Green weekend”? Join us, and you can make new friends and help protect the environment at the same time.

Park Life

Do you like playing and relaxing in the park with your friends? If so, why not take the chance to come with us and tidy up the park when you go? To add some fun, there is a gift for the person who collects the most rubbish! Meet us at the south entrance to Taohe Park at 9 a.m. next Saturday if you want to join in.

The Air You Breathe

A great way to make the air we breathe cleaner is by planting lots of trees！It is a fact that trees slowly filter (过滤) a lot of pollutants (污染物) from the air. So come and help us plant some new ones in Fenhe Park at 2 p.m. next Sunday.

War on Graffiti(涂鸦)

Some people think graffiti is cool. Well, it is not! The best way to stop buildings from becoming totally covered in ugly graffiti is to fix it as soon as possible. And that is exactly what we are going to do. We are repainting the school walls from 1 p.m. on Saturday. You don’t have to bring any tools, just remember to wear some old clothes!

4 . Animal rights activists respect animals because they understand animals have a place in the world. Zoos, especially the ones that are doing everything right, become a headache for the animal rights activists.

Zoo supporters argue that they save endangered species and educate the public, but many animal rights activists believe the costs are more than the benefits, and the violation(违反) of the rights of the individual animals is unreasonable. Roadside zoos, petting zoos, and smaller animal exhibitors tend to offer narrow space for the animals, keeping them in pens or cages. Sometimes, a tiger or bear will live with cold concrete（混凝土）and metal bars for their entire lives. Larger, trusted zoos try to avoid these operations by offering excellent treatment to the animals. However, to animal rights activists, the problem is not how well the animals are treated, but whether we have a right to limit (限制）them for our delight or “education”.

To zoo supporters, by bringing people and animals together, zoos educate the public and promote an appreciation of the animals, encouraging people to protect the animals. Zoos save endangered species by bringing them into a safe environment, where they are protected from poachers(偷猎者), habitat loss, hunger, and predators(捕食者). Many zoos also have various programs for endangered species. In the wild, these individuals might have trouble finding mates and multiplying(繁殖). A good zoo provides an enriched habitat in which the animals are never bored, are well cared for, and have plenty of space. Besides, zoos are a tradition, and a visit to a zoo is a healthy, family activity.

In the case of zoos, both sides—animal rights activists and zoo supporters will argue that their side saves animals. Whether or not zoos benefit the animal community, they certainly do make money. As long as there is need for zoos, they will continue to exist. We can start by making sure that conditions are the best possible for the animals who are limited to zoos.

6 . When Earth was just a tiny young thing，it birthed many new continents - then it swallowed them all up, leaving just a few traces behind, a new study shows.

These first continents had a special skill for living fast and dying young, but in doing so, they paved the way for solid continents that eventually led to the emergence of plate tectonics（版块运动）， the new study suggests.

For hundreds of millions of years, the current continents have been more or less stable. But very little is known about the continents that existed early on in Earth's history.

To learn more about that early history, the researchers used computers to model the interactions of rock and magma（岩浆） in the Earth’s crust（地壳） and below. The modeling showed that the earliest continents, known as the Hadean (4.6 to 4.0 billion years ago), were weak and likely to destruction. Modern continents have a comprehensive high tensile strength, meaning it’s hard to tear them apart by stretching.

By the time the Archean (4.0 billion to 2.5 billion years ago) began ending the Hadean, the crust which had first formed was almost entirely replaced by the seeds of the modern continents.

In a sense, the researchers found, those lost Hadean continents made the later, more stable continents possible.

The emergence of continents at the close of the Hadean also contributed fertilizer that would later help seed life on Earth, the researchers wrote. Bits of them broke off and entered the atmosphere and oceans, providing necessary nutrients for the life forms that soon emerged.

8 . TRAVEL ADVISORY

Here are a few things you should know before you take off on your next trip.

Frontier Airlines Face Covering Requirement

As required by federal law, the Centers for Disease Control (CDC) Order and Transportation Security Administration (TSA) Security Directive, all passengers and employees must wear a face covering over nose and mouth throughout the Frontier travel experience including at ticket counters, gate areas, baggage claim and onboard all flights. Face coverings are not required for children under the age of 2. Face coverings must fit snugly(紧密地) over your nose and mouth and be secured under the chin. Not wearing an approved face covering is a violation of federal law and you may lose future travel privileges on Frontier.

* Persons with a disability who cannot wear a mask, or cannot safely wear a mask, because of that disability as defined by the Americans with Disabilities Act can apply for a face mask exemption(豁免). To learn about pre-travel exemption requirements, click here.

Temperature Screening Requirement

Anyone with a temperature of 100.4 degrees Fahrenheit or higher will not be able to board the plane. If time allows, we will give customers the opportunity to rest before receiving a second check. If the second temperature screening is 100.4 degrees or higher, our team will help the customer to rebook travel on a later date when they are feeling better.

Know Your Travel Policy

CDC issued an Order on January 12, 2021(effective since January, 26, 2021) requiring proof of a negative COVID-19 test or documentation of having recovered from COVID-19 for all air passengers arriving from a foreign country to the US.
