George Aldrich, whose official title is chemical specialist, works at NASA's White Sands Test Facility in New Mexico. He uses his nose to protect astronauts from unpleasant or harmful odors (气味). His near four-decade career has involved smelling objects from technical handbooks to astronauts' personal things.

    It's crucial that all items taken aboard the International Space Station (ISS) are odorless. Since astronauts are allowed to bring personal items aboard, all their objects must be smell-checked before leaving Earth. In a video provided by Science Channel, Aldrich relates one specific occasion when an astronaut wanted to build a ship in a bottle in space. Everything in the ship-building process had to be sniffed—right down to the glue.

    Aldrich and his team are responsible for making sure that objects are not only odorless but also harmless to astronauts. When the ISS heats up, a process called off-gassing occurs, which means chemicals flow out from certain substances (物质). Objects that would be safe on Earth could give off unpleasant odors or become dangerous when exposed to high temperatures in the ISS's unique environment.

    Of course, humans aren't the only testers or the first to be exposed to potentially dangerous objects. Before Aldrich sticks his nose into a substance, it has been examined by machines. Even though machines can detect unsafe substances, computers cannot tell exactly how things smell to humans. While something could be technically fine, it could be smelly to an astronaut.

Aldrich's nose is not alone there. He is the head of a hard-sniffing team of smell testers. Together they smell each object and rate it on a scale (等级) of 1 to 4. According to NASA, 1 cannot be detected, and 4 is considered not bearable. After the scientists conclude their tests, the scores are averaged. If an item is rated more than 2.4 on the scale, it fails the test and is not allowed on the flight.

    Lawns（草坪）are some of the most common things in the world until you really start thinking about them. That's when you realize that they make no sense. Why do people keep these uninteresting, pointless little plants outside their homes? They're not beautiful like flowers, they don't provide food and you have to take care of them constantly.

    Israeli bestselling author Yuval Noah Harari thought these deeds were weird too. He looked into their history and ended up with an interesting story.

    No one considered putting patches of grass outside their homes in ancient times. That changed in the Middle Ages, when French and English kings and nobles started putting patches of grass at their castle entrances.

    “Well-kept lawns demand land and a lot of work,” wrote Harari in his book. “In exchange, they produce nothing of value.” Peasants could never afford to waste their time or land on lawns, so these lawns were a perfect status symbol（身份的象征）for nobility（高贵）.

    When the Industrial Revolution began in the 18th and 19th centuries, the middle classes started being able to afford their own suburban（郊区的）houses. And guess what became the suburban status symbol? A perfectly kept lawn.

    The popularity of lawns continued to grow, taking over public event spaces and sports. In the past, people played sports on all kinds of surfaces—dirt, ice, sand. But in the last couple centuries, they made the switch to green grass.

    “Grass is nowadays the most widespread crop in the USA after corn and wheat,” Harari continued. Lawns spread beyond Europe and the U.S, and they're now status symbols around the world.

    Suburban people may not realize it, but they care for lawns just because centuries ago, French and English kings wanted to show off by intentionally planting something useless. It's strange that people should continue to spend so much time and money on what's really a leftover（遗留物）from the Middle Ages. When you plan your house, you can shake off（摆脱）the cultural leftover and imagine for yourself a rock garden or some other new creation.

    “Why do I live? Why do I wish for anything, or do anything? Is there anything in my life that will not be destroyed by my death?”

    These are the words of the famous Russian writer Leo Tolstoy. Like Tolstoy, many people ask these difficult questions. And they struggle to find meaning in their life. Tolstoy spent his whole life trying to answer difficult questions like these. His search for answers influenced his writing.

    On August 28th, 1828, Leo Tolstoy was born in the country of Russia.

    As a child, Tolstoy was a member of the Russian Catholic Church. But as a young man, he began to question that faith. Tolstoy wanted to make his own moral decisions; he was tired of being told what to believe. He thought people could achieve a degree of perfection if they tried hard enough. So he worked very hard at being the best in everything he did. He thought that he would find meaning and truth in success.

    In the 1850s, Leo Tolstoy wrote his first stories. He wrote about his experiences in the army He also told stories about when he was a child. These works were published and Tolstoy became a well-known writer.

    Tolstoy was finally successful. He earned the respect he always wanted. Many wealthy and intelligent men met and talked with Tolstoy. Some of the men were writers like him. They talked a lot about faith and the meaning of life. But soon Tolstoy recognized that these men were not perfect. Now he knew they could not answer his questions about faith.

    So in the 1860s, Tolstoy tried a different way to find meaning. He opened a school for the children of his serfs -the people who worked on his land. These workers were very poor. He wanted to help them because he thought they were more honest than the wealthy people he knew.

    Tolstoy learned many things from his workers. He respected how they worked hard to provide for their families. He began to believe that marriage and family would give his life meaning. So in 1862, Leo Tolstoy married a young woman named Sonya Behrs.

    The next 15 years were the best years of Tolstoy's life. It was during this time that he wrote his most famous books -War and Peace and Anna Karenina. Many literature experts say that War and Peace is one of the greatest books ever written.

    Both War and Peace and Anna Karenina communicate Tolstoy's beliefs about the Russian nation, church and people. They also communicate what he thought was the answer to all his questions. Tolstoy believed humans were supposed to live a simple lite and take care of their families. Tolstoy thought this would satisfy him and bring him happiness.

    Leo Tolstoy is still a very respected writer today. His faith and writings have influenced many people. Tolstoy's search for the meaning of life is something everyone can understand. His teachings still interest people all over the world.

    It's a common belief that the roles actors play might somehow reflect their true personalities. It's usually not true, but British actress Phoebe Waller-Bridge, 34, is an exception.

    Just like Fleabag, the character she played in the comedy-drama series of the same name, Waller-Bridge feels that her life is a mess. "It's just really wonderful to know that a dirty and messed up woman can make it to the Emmys," she said. She may be "messed up", but Variety magazine calls her an "all-around icon".

    Last month, Waller-Bridge took home three Emmy awards for her work on Fleabag — best writing in a comedy series, best lead actress, and best comedy series.

    Her success is partly because of her family. Waller-Bridge was brought up in a free environment. Her mother always told her, "You can be whatever you want if you imagine it." So Waller-Bridge broke all the rules about what a "good" girl should do. "Our laws and moral codes don't apply — she lives without fear of consequence," The Sun noted.

    That fearlessness extends to being authentic (真实的) in her writing and acting. Unlike the can-do heroines and strong, successful women in many TV dramas, Waller-Bridge shows a flawed but real character. The character Fleabag was a screw-up who always found a way to say or do the wrong thing. "It resonated with the lives of stressed-out women everywhere in reality — doing their best to find balance in their lives," a viewer wrote on US movie website.

    Villanelle in Killing Eve, another hit TV series developed by Waller-Bridge, was a little bit violent but showed no interest for the rules others created, which make many people see themselves in her.

    "People have been scared to write characters like these. But I think, now, women are so relieved to have this new template (样板). And, aren't we all a bit of everything?" Waller-Bridge said in an interview with Indian Express.

    With such courage and sincerity, Waller-Bridge is, without a doubt, a "golden girl" in Hollywood, Australian news website The New Daily commented.

If you had to choose one word to describe Kevin,it might be "slow".He didn't learn his ABCs as fast as other kids.He never came first in the schoolyard races.However,his smile was bright and he showed great interest in everything.So when he discovered that Randy was putting together a boy's basketball team,Kevin immediately joined.

At practice,Kevin worked so hard that you'd have thought he was preparing for the NBA.And the whole team truly loved basketball.But just loving the game doesn't help you win.They lost every game that season by a very large margin(差距),except one...that night it snowed and the other team couldn't make it to the game.

At the end of the season,the boys unfortunately played against the first-place team.The game went pretty much as expected,and near the middle of the fourth quarter Kevin's team stood nearly 30 points behind.At that point,one of Kevin's teammates called time-out."Coach,this is our last game but Kevin has never made a basket.We should let him try," said the boy.With the game completely out of reach,the idea seemed reasonable.So every time Kevin's team had the ball,they would give it to Kevin.His first shot missed and he missed another shot again.This continued a few more times until the player from the other team grew wise.Instead of running off down the court,he threw the ball to Kevin who shot...and missed again.

Soon,all the players were circling Kevin,throwing the ball to him.The whole gymnasium thundered with the clapping,chanting,"Kevin!Kevin!" Finally,after amounts of tries,the ball went in.Kevin's arms shot high into the air and he shouted,"I won!I won!" The first-place team remained unbeaten,but on that evening,everyone left the game truly feeling like a winner.
