5 . A fresh and gentle wind on your face, soft sand under your feet and blue waters as far as the eye can see. Is there any other Olympic sport that is played in such pleasant conditions as beach volleyball？

“I’ve gone to a lot of beautiful places, and met a lot of beautiful people. That wouldn’t have happened if I had been playing another sport.” said Randy Stoklos, America’s most famous beach volleyball player.

The sport began as a four-a-side game on beaches in Southern California in the 1920s. The first recorded two-man game took place there in 1930, and the first tournament (锦标赛) was held in Los Angeles 18 years later. The winners were awarded a case of Pepsi. In the 1950s, women started playing and the sport soon spread to Europe and South America. Yet at that time, beach volleyball was more an entertainment show than a sport, with beauty contests included. The Association of Volleyball Professionals was founded in 1983 and beach volleyball developed into a fast, athletic sport. Its world-wide popularity won beach volleyball a place at the 1996 Olympics in Atalanta, where 24 male teams and 16 female teams took part. At present, the US and Brazil are the best in the world at beach volleyball.

The game came to China in the early 1990s and there have been national tournaments since 1994. It became an official event at the Eighth National Games in 1997. China’s You Wenhui and Wang Lu finished ninth in the women’s beach volleyball world championships in Brazil.

6 . Paper is one of our oldest, simplest and most important inventions. But it also presents a danger to the world in two significant ways. First, the making of paper requires the loss of millions of trees each year. Between 2001 and 2019, the world lost 386 million hectares of forest. Of the trees that were cut down, 42% went to paper production. And worldwide use of paper is expected to double in the next 40 years. Clearly, the planet cannot sustain such a high rate of forest loss.

The second great problem with paper is what happens once it is no longer useful. A huge quantity of wastepaper ends up in dumps and landfills (垃圾填埋场), where it can produce harmful gases. Paper in landfills leads to the release (释放) of methane, a gas that is a significant contributor in global warming.

One simple solution can greatly reduce both of these problems: paper recycling. Paper is mainly made from cellulose (纤维素), which makes up the cell walls of trees and many other plants. Because of its structure, cellulose can be used repeatedly in papermaking. So far, trees are the only source of cellulose that can fill the massive demand for paper products. Therefore, recycling paper is simply one of the best ways to save trees.

Thanks to advances in processing, recycled paper isn’t the dull-colored stuff many of us are familiar with any more. It now can offer the same print performance as non-recycled paper.

Effective recycling requires a consistent effort. The way to begin is with education and understanding. Once enough people realize the need for recycling, more effective recycling systems can be carried out. The massive loss of trees affects everybody on earth. Everyone should do their part to recycle paper and encourage government and industries to do the same.

8 . When it comes to being fit and healthy, we're often reminded to aim to walk 10,000 steps per day. This can be a frustrating target to achieve, especially when we're busy with work and other commitments.

The 10,000 steps a day target seems to have come about from a trade name pedometer sold in 1965 by Yamasa Clock in Japan. The device was called "Manpo-kei", which translates to "10,000 steps meter". This was a marketing tool for the device and has seemed to have stuck across the world as the daily step target. It's even included in daily activity targets by popular smart-watches, such as Fitbit.

In ancient Rome, distances were actually measured by counting steps. In fact, the word "mile" originated from the Latin phrase mila passum, which means about 2,000 steps. It's suggested the average person walks about 100 steps per minute，which would mean it would take a little under 20 minutes for the average person to walk a mile. So in order for someone to reach the 10,000-step goal, they would need to walk about five miles a day, nearly two hours of activity.

Researchers have investigated the 10,000 steps a day target. The fact that some studies have shown this step target improves heart health, mental health, and even lowers diabetes (糖尿病) risk, may, to some extent, explain why we have stuck with this number.

But while some research has shown health benefits at 10,000 steps, recent research from Harvard Medical School has shown that, on average, nearly 4,400 steps a day is enough to significantly lower the risk of death in women. This was when compared to only walking around 2,700 steps daily. The more steps people walked, the lower their risk of dying was, before leveling off at around 7,500 steps a day. No additional benefits were seen with more steps. Although it's uncertain whether similar results would be seen in men, it's one example of how moving a little bit more daily can improve health and lower risk of death.

10 . One day, Amanda was diagnosed (诊断) with cancer of an early stage. During this time, she was admitted to a college. She planned to save money to meet the college expense and then seek medical treatment for the cancer.

Her father, Clint and her friends didn’t want her to put off her treatment due to the expense. They took matters into their own hands and started a GoFundMe campaign. A longtime friend of the family was cofounder of a group named Praynksters, known for random acts of kindness. The friend decided to use their own group to help the family. The group came up with the creative idea to spread the word and invite families, friends, and strangers who wanted to help to take part in a donation activity. The event induced the enormous assistance from the local community.

Clint and Amanda were moved as the crowd passed by and the donations poured in. The event brought the family over $13, 000 in donations to go towards her medical treatments. The generous act of kindness gave the family a comforting, and optimistic feeling during a time when all hope seemed lost. Clint said that Amanda struggled with the idea of asking for help. She felt guilty and undeserving compared to others who are also struggling. She is still humbled by it all.

After several months of treatment, life for the family has started getting back to their normal routine. Once Amanda got her strength back, she returned to school and completed her bachelor's degree. The family is now inspired to volunteer in their local neighborhood and contribute to crowdfunding (众筹) efforts. They are grateful for the opportunity to give back and help others as many have helped them.
