Medical developments and discoveries often provide the best things for controversies (争论).This is because whenever a new discovery or theory is proposed, there is always disagreement. Only via objective scientific evidence can such arguments be cleared. But, as is often the case, a clear solution is not instantly found. However, once the technology catches up with the area of the discovery, it shows exactly how valid the theory is. Since this is a slow process and can take years, the development of controversies is unavoidable.
Over the years, various such controversies have been developed, examined, and either rejected, or proved right for the good of mankind. Now read the following examples.
Firstly, cancer was largely regarded as an incurable disease, since its exact cause was unknown. Later, professors and doctors came up with various theories regarding the cause. Some claimed it was the result of chemical processes, while others believed it was a sort of poison. After a few decades, a doctor proposed that cancer was caused by the inhalation (吸入) of pollutants, in the form of smoke, gas, etc. His claim was rejected by many researchers and doctors. However, due to various scientific studies, this claim is now clearly common knowledge, though there may be other causes.
Many people worry that the use of cell phones can cause cancer. Recent studies suggest that this common threat is actually quite true. Numerous studies indicate that the long usage of cell phones (at least an hour per day) increases the risk of developing brain tumors.
After the discovery of X-rays, they were widely used, from doctors' clinics to shoe stores to see the fit of shoes. People thought they could offer the benefit of visualizing the skeleton (骨骼) of a person without causing any danger to the person. However, in 1956, the National Academy of Science reported the harmful effects of these rays on the human body, and the practice was then given up. Presently, we all know that exposure to X-rays may lead to radiation poisoning, tissue breakdown, and even death.

Christina Horsten and Felix Zeltner tried not to panic when they were hit with a $400 rent increase on their Park Slope apartment in 2016, and realized they would have to move for the second time in two years. Instead of feeling intimidated by the unexpected event, they hit upon an unconventional idea: Why not move to a new neighborhood every month for a year?
At first, things went remarkably well. They found their next apartment, a beautiful apartment in Chinatown. The next months brought stops in Staten Island and Harlem. As September approached, their next place to live proved difficult to find. When their Harlem lease (租约) ended, they took a road trip, then fell for a false advertisement in Sunset Park, Brooklyn, when an apartment they found advertised online wasn't actually available to rent. And eventually they got their money back through Paypal. “That was rock bottom,” Ms. Horsten said.
Over the rest of the year, they spent time in a townhouse in Mott Haven, as well as apartments in Chelsea, the East Village, Hell’s Kitchen, and Williamsburg. “In the end, we were like, ‘Why should we even stop doing this?’ ”Ms. Horsten said. But then a lease takeover on Listings Project caught their attention: a two-bedroom apartment atop an Upper West Side townhouse.
A second daughter, Lily, was born in January. And with a newborn, they have no intention of moving again anytime soon. Still, many aspects of their adventure have remained with them. “In the same way that we’ve tried to keep minimalism (极简主义) in our life, we try to stay in touch with all the people we’ve met,” Ms. Horsten said.“We realized it was a lifelong project to try to get to know NewYork City,” she added. But there is one member of the household eagerly waiting for a repeat: their 4-year-old daughter Emma.“ I think she loved it the most,” Ms. Horsten said.“At all the places we stayed, she found things I never noticed: children’s books, a dollhouse, a drum set. Even now, she’s like,‘When are we moving to a new home?’ And we’re like,‘We kind of like it here.’ ”

Home party marketing originated in America in the early twentieth century. At that time, direct selling had become a very common part of American life. Door-to-door salesmen would travel throughout the country selling anything from sewing machines to cure-all medicines. In 1931, a man named Frank Stanley Beveridge who had dug enough gold by doing this selling started a company called Stanley Home Products. The company sold cleaning supplies to housewives.
Soon after Mr. Beveridge began his company, one of his salesmen began selling Stanley products at home parties. The salesman would organize a Stanley Party where he could give a cleaning demonstration (演示) to a room full of guests. It allowed him to sell Stanley products to many different customers at once, and it proved to be much more effective than standard door-to-door sales. The practice quickly became the main marketing strategy (策略) of Stanley Home Products.
Next, during the 1940s, many housewives started selling Stanley products to make extra money for their families. The job was perfect for housewives because Stanley sellers could work from home and set their own schedules. A single mother named Brownie Wise took full advantage of this opportunity and quickly became one of Stanley’s top sellers.
Not long after that, she started her own direct selling business called Tupperware Patio Parties, which focused on selling a new type of plastic food container, Tupperware, using the Stanley home party system. Wise had realized Tupperware was perfect for the home party system. She could show her customers its patented (专利的) airtight seal, and she could also take away their anxiety about the safety of plastics -a fairly new invention at the time. Wise’ s company was very successful, and it was soon selling more Tupperware than department stores.
Today, many other companies have adopted home party marketing plans. So, next time you leave friend’s party with a hundred dollars’ worth of new Tupperware or jewelry, you can thank Frank Stanley Beveridge and Brownie Wise for your unintended purchase.

Architect Daniel Libeskind is the designer of such global landmarks as New York's One World Trade Center and Berlin's Jewish Museum. In his new book, he reviews his life's work and its inspirations — including these books.
Alice's Adventures in Wonderland and Through the Looking-Glass by Lewis Carroll. I love Lewis Carroll; he's a total genius (天才). His two classic works are children's books for grown-ups because they show aspects of the creative mind that we all have but seldom use in adulthood. Inspired by Carroll, I make a habit of trying to learn seven amazing things before breakfast.
Ulysses by James Joyce. Joyce once said that if Dublin were destroyed, you could recreate the entire city from this novel. You can't do urban planning without Ulysses because it is a labyrinth (迷宫) you can never leave.
In Search of Lost Time by Marcel Proust. Proust's great novel is really a book of reflections about how architecture — our living spaces — creates a blueprint (蓝图) for our dreams, our desires, our emotions, and our memories. Where we have lived, what we have eaten, and what kind of cups we use — all of those aspects are examined here in minute detail.
Emily Dickinson's Herbarium by Emily Dickinson. From childhood onward, Dickinson collected, pressed, and classified the plants she grew in her garden in Amherst.

You don't even have to read her poetry to see what a great artist she was.

Two years before，My sister and I got a chance to take a bike trip. The journey was really hard, especial in the mountains. At first，our leg were so heavy and cold that they felt like blocks of ice. Have you ever seen snowmen to ride bicycles? That's how we looked like. Along the way, children dressing in long wool coats stopped to look us. We found it was so cold that my water bottles freezes. To climb the mountain was hard work and as we looked around, we were surprised to see beautiful lakes shining like glass in the setting sun. What a unforgettable experience!
