Inventors are always at work, dreaming up new technologies. Some inventions help us solve problems. Others make life easier, or more fun. Here, TFK(Time for Kids) presents 3 of our favorite inventions. See how they make us live a better life.
Stopping Sickness
Christine Schindler is an engineer. She wanted to help stop the spread of foodborne illnesses. So she created PATHSPOT. It uses light to scan a person's hands for harmful germs. Restaurant employees hold their hands beneath the scanner. Then the scanner judges whether they must be rewashed. About 100 locations have started using the product since it launched in May.
Talking Eyes
For people who are blind or have other visual problems, the ORCAM MYEYE 2 could be a game changer. It might also prove useful for people with reading difficulties. Described as "talking glasses," this AI device can be attached to any eyeglass frame. It can identify faces. It can also read text aloud. Fitting all this power into such a small device is like "putting an elephant in a small closet," says Amnon Shashua, the inventor of the technology. Now the device can be bought online.
Sport-safe
Research shows that playing football increases the risk of brain injury. Still, about a million kids under the age of 13 play football, according to the Sports & Fitness Industry Association. That's where the VICIS ZERO1 YOUTH football helmet comes in. It has thick, force-absorbing support on the front and sides, where kids are likely to take the hardest hits on the field. Players on 1,500 youth teams have worn the helmet.
"I want to work full-time in China, honey." An overseas call awakened the wife from sound sleep. "Why?" asked the wife with surprise, in a drowsy（昏昏欲睡的）voice, from the other side of the ocean.
In the United States, he had a great future ahead. At the age of 36, he became the youngest professor in the history of the Department of Molecular Biology at Princeton University, for his academic achievements. At 40, he became a tenured（终身的）chair professor at Princeton.
When everything seemed perfect and admirable to others, he firmly decided to say goodbye to Princeton University, to an affluent life in the United States, and return to China.
The news spread explosively. Many expressed confusion, many persuaded him, many made fun of him, and still many waited to have a good laugh at him.
He said patriotism is the plainest feeling of a person. Who doesn't love his motherland, after all? In his heart, the American dream is already something past; the Chinese dream is rising.
After returning to China, he devoted all his energy, worked like crazy, and determined to do something big. He formed a life science research team. Every day, he works 12 to 16 hours at his laboratory.
He is Shi Yigong, nicknamed "Da Niu"（someone with extraordinary achievements）by Tsinghua students. His given name, Yigong, comes from an idiom that means "devoted to public interest whole-heartedly". "So far as I' m concerned, awards are of no special meaning." Shi says calmly.
In his 18 years of study in the United States, he never forgot his Chinese dream. In the next 18 years, the Chinese dream will be more beautiful and greater by the efforts of Shi Yigong and the likes of him.
The world's first robot police officer has started working. Its name is ‘RoboCop' and it went into service for the Dubai Police earlier this week. Robocop's first official duty was to greet guests at the opening of a security conference in Dubai. Apart from greeting visitors, its job was to answer questions and give directions. RoboCop has a built-in tablet for people to interact with. People can use the tablet to pay traffic fines and use other smart police services. The tablet is linked to a police station, so people can talk to human police officers. In addition, RoboCop can speak six languages, including English and Arabic. The 170 - centimetre - tall robot can also shake hands, salute people and recognize people's emotions and facial expressions.
Dubai Police says RoboCop is the first of many robot police officers for the city. A spokesman said that by 2030, 25 per cent of the Dubai Police force will be robots. He said: "We are looking to make everything smart in Dubai Police. By 2030, we will have the first smart police station which won't require human employees."
"The RoboCop is the latest smart addition to the police force and has been designed to help us fight crime, keep the city safe and improve happiness levels," He added. He also said that RoboCop would, "assist and help people in the malls or on the streets". An official at the security conference commented that the future is here now, saying: "The age of the robots is no longer coming. It has arrived."
If you make a list of the world's top ten most challenging jobs, chances are that being a teacher will not make the cut. But think about the discouraging task millions of educators face each day as they try to shape a group of often bad-tempered, wild kids into intelligent, well-rounded individuals. That surely has to be the toughest job in the world, especially given that there is no promotion or bonus awaiting them even if they are wildly successful!
What if these all-important individuals that we often take for granted disappear from our lives? That was what Project Ed and Participant Media's Teach campaign asked filmmakers of all ages to imagine in their recently-held competition. Entitled "A World Without Teachers", its purpose was to inspire more young people to become teachers. However, the 62 amazing video submissions also serve as a reminder of how horrible things would be if we didn't have these selfless individuals guiding us through life. What was interesting is that even the youngest participants did not appear to be happy at the idea of not having anybody telling them what to do.
High-school student Savannah Wakefield reflected if art as we know it today would have been different without teachers. Would Monet have discovered his talent for impressionism? Los Angeles-based Miles Horst, who won the 1000 USD prize for the best adult submission imagines a world where teachers are replaced by a "brain box" in his fun lively entry.
Youth category winner Marina Barham's video represents a fact we all know but often forget. Teachers don't just teach, they inspire—something that no electronic device, no matter how smart, can do! So the next time you think your teacher is being "mean" for trying to channel you in the right direction, imagine a life without him/her. We have a feeling it will not appear as rosy!
Running is the best way to keep our body fit and healthy. Those who want to burn fat and lose weight can run regularly in the morning.When you run in the gentle morning atmosphere, you will get the psychological benefits along with the physical benefits. Running is more effective and also less time-consuming. Besides, in your busy day, morning is the free time to take some exercise.
Dr. Scott Collier from the State University did a study on some groups of people of 40-60 years old. They walked or ran at 7 am, 1 pm and 7 pm. From this study, he saw that the group of early exercisers experienced 10 percent drop in their blood pressure. So, we see that early morning run benefits us for the long term.
Another benefit of running is the stress relief. Every day running in the morning will help you to keep your mind fresh to start your daily work.It will save you one step ahead to reach your goal. It provides you with a positive mood for a day.
Running is the best way to lose weight. But you should add some other training to build your muscle and burn fat. Some elite athletes（优秀运动员）say that when you wake up in the morning, you should first run for a while.
Most of the busy people do not have enough time to communicate properly with the family and social people.The morning exercise such as running and walking gives us the opportunity to meet our neighbors. We can talk with them in the morning.

I first heard about several cases of coronavirus(冠状病毒) infection in January, but I did not expect the outbreak to affect the rest of the world. Starting in March, it was1that we should take all the final exams online. It was unexpected, and all university staff and students were2.
Due to the disease, most of the school events have been3to be held online. I have had a lot more4time than before. To5time, I learned to follow recipes(食谱)to make6dishes. The period of quarantine (隔离) has become a7that I can learn some new life skills. Besides cooking, I have been 8a new hobby—playing puzzles.

以前看似奇怪的事情现在对她来说显得十分平常了。
努力学习之余，我还参加了一些社交活动。
与来自不同文化背景的人合作有助于我们从不同角度看世界，进而让我们对自己文化有更深入的了解。
简单地说，这句话就是"人如其食"的意思。
这意味着咀嚼过快的人最终会吃太多食物，因为他们仍然感到饥饿。
从车窗往外望去，加拿大巍峨的山脉和辽阔的森林尽收眼底。
得知她们只能在蒙特利尔逗留一天时他说到："那太可惜了, 你们应该多呆几天。……"
我们疲惫不堪，饥肠辘辘，也不认识一个汉字，不知道该怎么点餐，所以厨师径自在我们的桌子上摆满食物，那是我吃过的最可口的佳肴。
尽管交通拥挤，他还是设法准时来了。
直到他毕业我才知道他的抱负。
1）你良好的饮食习惯；
2）你不良的饮食习惯；
