It is a fact that people die every moment of every day. However, the deaths of those who have done great work in the public field can be especially shocking and heartbreaking— e1. to those of us who don't know them personally.
On Jan 26, Kobe Bryant, one of the most legendary (传奇的) NBA players in history, died in a terrible a2.. He was 41 years old when a helicopter he was riding in crashed, killing him and eight others, including his 13-year-old daughter Gianna Bryant.
Following Bryant's death, people from all walks of life have s3. respect to the late basketball superstar--not just for his achievements on the court (球场), but also for his personality and the inspiration (激励) he has given to us.
In the basketball world, Bryant ranks (排名) a4. the top players of all time. He entered the NBA directly from high school as a basketball prodigy (神童). He played his whole 20-year career with the Los Angeles Lakers and helped the team win five NBA championships. He was fast, skillful and aggressive (进攻性的), which earned him the nickname Black Mamba, one of the most deadly snakes in the world. That's w5. his competitive philosophy (哲学) is known as the "Mamba mentality".
"Mamba mentality is you're going, you're competing, you're not worried about the end result," Bryant said. "It's all about focusing on the p6. and trusting in the hard work when it matters most."
Off the court, Bryant was known as a successful businessman, an Oscar-winning filmmaker, and a proud father of four daughters.
The fact that Bryant is no longer with us is sad. We'll never see him play in a7. game. But the work he has done will keep inspiring us years after his death.
Some days, don't you think, "Wouldn't it be nice if the laundry would just do itself?" Self-cleaning clothes may sound crazy. But Australian researchers have found a way to make something like this _______!
A team at RMIT University in Melbourne, Australia, found a way to put special nanostructures (纳米结构) into clothing, which can then clean the clothes. When sunlight hits the nanostructures, they break down dirt. The nanostructures don't break down the actual clothing because cotton and the other clothing materials are too strong to be _______.
According to CNN, the researchers covered the clothing in a solution made of silver and copper (铜) nanostructures. _______ it takes is 40 minutes of sunlight and your clothes will look as good as new.
So if you spill on yourself during lunch, you can step outside for a walk, and it will be clean _______ the time you go inside. It not only makes your life easier, but can also be good for the climate.
According to the US Department of Energy, the average load of laundry uses about 25 gallons (about 94 liters) of water. Water is a very important resource, so using _______ of it to wash clothes is better for the environment. So one of the scientists at RMIT University knows more needs to be done.
"There's more work to do before we can start _______ our washing machines," said DiRajesh Ramanathan, "but this is a strong foundation (基础)."
So what's the next step? Ramanathan wants to either start selling the solution by itself or convincing clothing makers to treat their clothing with the solution.

Masks, a simple protective tool, have been used by people for a long time. They can not only prevent epidemics, but also protect us from other harmful things, such as smog (雾霾) and chemicals. When was the protective mask first invented and how did it develop? Let's take a look.
1st century At this time, lots of people in the Roman Empire worked underground in mines (矿井). Many died of lung (肺部) diseases caused by dust. Pliny the Elder (23-79), a Roman philosopher, used animal bladders (膀胱) to protect miners from the dust. This was the first recorded use of protective masks. |
16thcentury Italian artist and inventor Leonardo da Vinci (1452-1519) advised people to wear a woven (纺织的) cloth dipped in water over their faces to protect against harmful chemicals. |
19th century In 1848, American Lewis Hassley became the first person to patent (注册专利) a protective mask for miners. In 1897, Polish-Austrian doctor Johann von Mikulicz Radecki designed a simple mask with one layer of gauze (纱布). He advised medical workers to wear it to prevent infection. This was the first use of a surgical (外科的) mask. |
20th Century In 1910, the pneumonic plague (肺鼠疫) broke out in Northeast China. Chinese doctor Wu Liande designed a face mask called 'Wu's mask'. It was made of two layers of gauze. The mask was praised by experts around the world because it could be produced easily and cheaply. |
Today With several outbreaks of flu and the air pollution in recent years, masks have continued to develop. For example, in 2012, when China suffered from smog, mask models such as N95 and KN95 became popular. They can filter out (过滤掉) fine particulate matter (微粒物). China is now the world's largest mask producer, making out half of the world's masks. |
