Can you imagine a cloud floating in the middle of your room? Do you want to know what it feels like to fly like a bird? Find your answers in Time Magazine's 25"Best Inventions". Here, we have picked out the most interesting 4 to share with you.
Talking Gloves
Ever felt confused by the sign language used by disabled people? Here is the "helping hand" you need. Four Ukrainian students have created a pair of gloves that helps people with hearing and speech problems communicate with others. The gloves are equipped with sensors that recognize sign language and translate it into text on a smart phone. Then the smart phone changes the text to spoken words.
Google Glasses
Google Glasses are like a computer built into the frame of a pair of glasses. With its 1. 3-centimeter display, the glasses allow you to surf the Internet and make calls without even lifting a finger. The glasses also have a camera and GPS mapping system. Users can take and share photos, check maps and surf the Internet just by looking up, down, left and right.
Indoor Clouds
It's not virtual but a real world. Dutch artist Smilde managed to create a small but perfect white cloud in the middle of a room using a fog machine. But it required careful planning-the temperature, humidity and lighting all had to be just right. Once everything was ready, the cloud formed in the air with the machine. But it only lasted for a short while.
Wingsuits
The suit realizes your dream of flying like a bird. Well, not exactly flying, but gliding through the air. It increases the surface area of the human body, which makes it easier for people to float in the air. Fliers wearing wingsuits can glide one kilometer in about 30seconds.
A jobless man applied for the position of "office boy" at Microsoft. The HR manager interviewed him and then watched him cleaning the floor as a test. "You are employed," he said. "Give me your e-mail address and I'lI send you the application to fill in, as well as date when you may start. "The man replied, "But I don't have a computer, neither an e-mail." "I'm sorry." said the HR manager, "If you don't have an e-mail, that means you do not exist. And whoever doesn't exist cannot have the job. "
The man left with no hope at all. He didn't know what to do, with only ten dollars in his pocket. He then decided to go to the supermarket and buy 10kg tomatoes. He then sold the tomatoes from door to door. In less than two hours, he succeeded in doubling his money. He repeated the operation three times, and returned home happily with 60 dollars.
The man realized that he could survive in this way, and started to go every day early, and return late. Thus, his money doubled or tripled every day. Shortly, he bought a cart, then a truck, and then he had his own fleet of delivery vehicles. Five years later, the man was one of the biggest food retailers in the US.
He started to plan his family's future and decided to have a life insurance. He called an insurance broker and chose a protection plan. When the conversation was concluded, the broker asked him his e-mail. The man replied, "I don't have an e-mail." The broker answered curiously, "You don't have an e-mail, and yet have succeeded to build an empire. Can you imagine what you could have been if you had an e-mail?" The man thought for a while and replied, "Yes, I'd be an office boy at Microsoft!"
WHAT are scientists? They are often described as gray-haired white-coated dull scholars.
But the world has changed. Young scientists are making their voices heard and releasing their powers on the world stage.
This is also true in China. Rising stars include new materials expert Gong Yongji, university professor Liu Mingzhen, and biologist Wang Ruixue. At the age of 28 in 2018, Wan Ruixue received the 2018 Science & SciLifeLab Prize for Young Scientists. This is a global prize to reward outstanding scientists at an early stage of their careers.
She focuses mainly on biomedicine(生物医学)and artificial intelligence(人工智能). "Both are cutting-edge(前沿)technologies at an early stage of development, " she said.
"So, I think they have great potential to be developed. I think in the study of cutting-edge technologies, China and other leading countries in the world are standing on the same starting line. And in the study of structural biology, China is likely to become the leader. "
She felt it was her fate to become a biologist. "I grew interested in the natural world, when I was very young, " she said. In 2009, she entered Sun Yat-sen University.
In her third year at the university, she realized that she wanted to do something related to biomedicine. So she emailed China's top biologist Shi Yigong, hoping to join his lab at Tsinghua University.
Shi recognized her talent and welcomed her. Years of efforts at the lab have paid off. Her research on the high-definition 3D structure of spliceosome led to a scientific breakthrough.
Unlike-many of other young scientists who choose to pursue further study abroad, Wan currently has no plan to go overseas.
"The whole ecosystem for scientific research is continually improving in China," she said, adding the country has great science facilities.
In New Jersey, there's a row of houses with a green lawn(草坪) that kids can't enjoy. "It's really frustrating. These lawns are useless to me, "Alice, a suburban mom in New Jersey said. She lives in a beautiful community full of green lawns.
It's the middle of summer, but there are no dandelions in sight. And that's the problem: the lawns are so green because they're full of pesticides, Warning signs urge parents to keep kids off the chemical-laden grass.
Alice says that most lawns and parks in her area are like this. There are plenty of them, but her kids can't play in them. "I just want to let my baby experience the grass," she said. " Also, I'm sure it's not good for animals. The other day, a woman found a dead deer in her backyard. "
In the 1940s, people often mixed clover with grass to keep lawns strong, which benefited the environment. But over the last few decades, pesticides have taken over. In 2012, the world spent $ 56 billion on pesticides. They go into farms, lawns, parks and just about anywhere where humans grow plants. These chemicals keep parks' grass and flowers perfect. They just make them useless as actual parks.
That may be more than just annoying. New research has shown that play is good for kids. It helps them discover the world and learn how to get along with other people. But it's hard to get enough play when there are so few public spaces where kids can play. And the few that exist are often covered in chemicals that make parents uncomfortable.
There are things to take the place of pesticides, like planting a lawn full of clover, Besides, maybe a dandelion here or there isn't the worst thing.

Your mind is also like that. When it is 11, just let it be. Give it a little 12. It will settle down on its own. You don't have to put in any effort to calm it down. It is 13. "
What did the professor emphasize here? He said, "It is effortless. Having 'peace of mind' is not a strenuous job; it is an effortless 14. When there is peace 15 you, that peace permeates to the outside. It spread around you and in the environment, such that people around start feeling that peace and grace.

Arthur was messy. He didn't try to make messes, but he didn't try to clean up much, either. There were always small pieces of food on the table when he was done eating. His socks never made it into the hamper (洗衣篮). And he only picked up his toys when Mom threatened to throw them away. Most days, Mom followed Arthur around the house and cleaned up after him. She brushed the crumbs (碎屑) into her hand and threw them away after meals. She picked up his socks and made sure they got washed, dried and folded neatly before going back in the drawer. She often picked up his toys when he left them to do something else.
One day, Mom asked Arthur to pick up his toy trains. "Not right now," Arthur said. He was reading a comic book. The trains had been on the living room floor since the morning.
"You know what, Arthur? I'm not going to ask you again. I'm done cleaning today." And with that. Mom put her feet up on the sofa and picked up a book to read.
At dinner time, Arthur noticed that there was a big pile of crumbs at his place at the table. Mom's spot was nice and clean. Arthur didn't like the crumbs very much. After dinner, Arthur's feet felt cold. He went to his room and opened his drawer, but the drawer was empty. "Mom, where are my socks?" Arthur called.
"There weren't any socks in your hamper, so I didn't wash them," Mom said. Arthur felt unhappy. Now his feet would be cold, unless he wanted to wear dirty socks from the floor. He decided to stay barefoot.
When it was time for bed, Arthur said good night to Mom and turned to go upstairs. Arthur stepped right on his toy train in his bare feet. "Ouch!" cried Arthur. "That really hurt!"
Paragraph 1:
However, Mom was still reading and said nothing.
Paragraph 2:
"Mom?" said Arthur. "Tomorrow can you show me how to do the washing so I can wash my socks?"
