Isaac Newton, the great British scientist, is often so deep in his thoughts that he will forget to eat his dinner.

    One day his friend came to have dinner with him. Dinner was put on the table but Newton didn't come out of his study（书房）. His friend sat down and waited for him. After waiting for quite a long time, he decided that Newton must be so deep in some new theory that he forgot all about the dinner. So he began to eat the chicken without Newton.

    When he finished, he thought he would play a joke on his friend. He put all the chicken bones（骨头）back on the dish and covered them with the dish over. Then he left Newton's house. He was quite certain that his joke would work.

    Several hours later, Newton came out of his study, feeling very hungry. He saw the table was ready for dinner and so he sat down. When he lifted the cover and saw the bones of the chicken, he was greatly surprised. He turned, looked at the clock, and saw that it was long past his usual time for dinner.

    "Well, well," he said to himself, "I thought I ate nothing, but I am wrong." He got up from table and went back to his study and began to work again.

HERE comes good news for travelers who often find themselves travelling to and from Shenzhen Bao'an International Airport during the late hours—the Airport Express now operates around the clock,according to the city's transportation authority

Starting from Saturday,Shenzhen Bus Group began to offer overnight service on eight Airport Express routes,providing seamless(无空隙的)connections to the latest arriving flights at the airport.These routes cover Futian,Luohu,Nanshan,Bao'an, Longgang,Longhua,Guangming,and  Pingshan  districts.The fares remain the same as daytime.

"Convenient and efficient ground transportation services are essential for a world-class international airport.The new service will enhance the travel experience of late-night arriving passengers and ensure reliable public transportation during nighttime travel,reflecting the warmth of Shenzhen,"the spokesman of Shenzhen Bus Group has said.

After arriving at the airport late at night,travelers can follow the sign to reach the Airport Express ticket counter at Gate 17 of the Ground Transportation Center to buy tickets.

Ms.Lan,who arrived in Shenzhen from Phnom Penh,Cambodia,early Saturday, noticed that there were still staff members from the Airport Express on duty although it was already 3:30 a.m.

"They told me they now offer overnight operations,making it convenient for late-night arrivals to reach their homes.This is great!"Lan,who lives in Guangming District,said.

During the Tang Dynasty (618-907), Emperor Taizong asked the prime minister Feng Deyi to recommend（推荐） talented people.

 1 , several months passed, Feng didn't recommend anyone. "I tried my best, but there are not unusual and 2 people at all, " Feng said.

"People are like utensils (器具). What we need to do is to make good use of their strengths. You cannot excuse yourself for not noticing talented people. How could you say that there are no talented people in our country?" said the emperor.

Indeed, each utensil or tool has its use. A knife is made to cut things while chopsticks are made to 3 food. We can't use a knife as a 4 . Like a utensil, each person has special strength. Nobody is perfect. We can't expect a person to be good at everything.

With this idea in 5 , Emperor Taizong discovered many talented people of different backgrounds. He 6 them important positions, which helped them make the best use of their talents. His talented people helped the society 7 and created a "golden age".

Some people say if a person is talented 8 , we should give them a chance. The same idea can be found in The Analects of Confucius (《论语》). Treating people as utensils shows that we can not only lead people well, but also allow different kinds of people to work well.

Today, the idea still makes 9 . If we become leaders someday, we should help others give full play to their strengths. 10 , Liu Bang let Zhang Liang and Xiao He work as advisors for their wisdom while inviting Han Xin to lead the army for his war strategies. Known as the "three heroes of the early Han Dynasty", they helped Liu build strong dynasty.

 For years, scientists have been researching how exposing(暴露) humans to nature may improve their physical and mental health. People are encouraged to visit forests and grow houseplants. Now researchers are also testing whether we can get some of the same benefits from experiencing nature in VR(虚拟现实). 

 Scientists are trying to understand what exactly about nature makes a real difference in health results. One tool that might help is VR, says Hector Alvarez, who wanted to find out if simply seeing nature can relax people. In an experiment, VR allowed him to expose people to the visual(视觉的) experience of nature while controlling temperature, light and air pollution. He is now preparing to publish his research. 

 People can feel safe faster in environments with lots of plants, Hector explains. "That's why I was interested in VR. If it is right that we feel safe faster in nature, it should bring your stress levels down. "

 So far, Hector says, research shows there are some health improvements by experiencing nature in VR. However, they are smaller than those got in the real nature. 

 Gretchen Daily is an environmental scientist at Stanford University. She agrees at parts of this research, especially in situations without nature. But in the long term, connection with nature in the real world can not be replaced. To some degree, Gretchen worries that the idea might take off that VR can replace the real thing. "If that's taken very far, that' ll be really harmful overall because the real thing is necessary in so many ways, " she says. "We just cannot live on a dead planet. "
