Many people believe that future driverless cars will our daily travel in Guangzhou.

To solve the problem, the city government decided to build new subway lines, and the supported the project .

Every year, the number of people choosing shared bikes to travel in Guangzhou continuously.

During rush hours, the on Tianhe Road the one on Tiyuxi Road.

Do you use different passwords for your email, bank, and other accounts? For safety reasons, researchers advise us to remember them in our hearts, i of writing them down. However, many people have trouble remembering so many passwords.

An IT company now has a solution: a t microchip placed under the skin. It's so small that others won't even n it.

The company tested this in Stockholm. Volunteers found that with the microchip, they could enter offices without cards, log into computers immediately, and even pay for canteen meals—all without passwords.

People have different o on this technology. Some welcome the convenience, while others w if it is truly safe, expressing worries about health effects.

This technology is developing fast. Perhaps in the future, we will all use such chips and never forget a password again!

Drones can do a lot of things for us, taking photos, delivering things from packages to pizzas to beer and following wild animals.

Can you believe it? US company IBM has made this kind of drone. It can deliver coffee to sleepy people. The drone can know when to bring a cup of coffee by studying a person's personal information. Then, the drone will fly to the person. It helps the drone to give coffee. The drone can also learn about someone's coffee drinking habits and tell when someone needs the next cup of coffee.

One company in Africa uses drones to deliver medicine and blood fast and save many people's lives. The drones can fly at speeds of up to 60 mph and when they are within a minute of the destination, the doctors get a message and wait nearby. The drone drops off the package and then goes back home.

A 92-year-old man in Virginia was lost and had to spend a night in the forest. The police looked for him all night but could not find him. Also, drones helped firefighters know about the fire in wildfire fight.

A. There is a special device under the drone.

B. But they have other uses now.

C. Luckily, the drone tracked him down in 20 minutes.

D. Drones can serve people coffee.

E. Drones can also save lives.

Stand in front of a mirror and look at it. How much do you really know about the person in it?

It's not an easy job to know ourselves. To help students do this important task, schools across China are providing more classes and activities on self-knowledge.

Liu Yue is a teacher from Chengdu Yucai Middle School. She has recently given her students a useful tool. "It's called the Johari Window, developed by two U.S. psychologists (心理学家)," said Liu. "It has four areas about one's self: An open area that everyone knows about, a hidden area that only you know, a blind spot that everyone knows except for you and an unknown area that nobody knows. Using this tool, students did a great job seeing themselves in a new way."

"I'm most curious about my blind spot," said eighth-grader Yang Manfei. "So I did a survey with my friends." The results showed that she easily gets anxious and impatient because of procrastination, the habit of delaying doing things until the last moment. "It is a bad habit I've never realized," Yang said.

"I find the unknown area most magical," said Sun Boyin, another student. "It means everyone has lots of potential (潜能)." When Sun entered middle school, he was not good at math. "But I set a goal and did lots of math exercises. Now I'm much better at the subject. The unknown part of my math ability is getting clearer," he said.

When it came to the hidden area, most students kept silent. "I'm afraid to show my secrets deep down," said Li Yixuan. "Then one classmate stood up and said his favourite cartoon is Tom and Jerry." Li thought to himself, "Am I brave enough to show my childish hobby? I want my classmates to see me as a grown person, not a silly child." But then he realized that classmate wasn't silly at all. In fact, he has the courage to be himself. "Show yourself and make yourself better. That's the best lesson I've learned," Li added.

Dear friends, do you want to learn more about yourself using the Johari Window? Which part would you like to find out most now and why? Please share your idea and a reason here. ________

Sub-heading 1: ________

Yang was born on September 22, 1922, in Hefei, China. He grew up near Tsinghua University, where his father was a mathematics professor. In 1946, Yang went to the University of Chicago for further study. He was attracted by its active research environment and the chance to learn from famous scientists like Enrico Fermi.

Fermi had a great influence on Yang. Yang told the New Yorker in 1962 that Fermi taught him "that physics should not be an expert's subject; physics is to be built from the ground up, brick by brick, layer by layer. We learned that abstractions come after detailed foundation work, not before."

At Chicago, Yang first worked in an experimental lab. However, he soon realized he was not good at experimental work. "I was clumsy in the laboratory, and all my fellow graduate students laughed at me," Yang told the Simons Foundation in 2011, "but they liked me as a person, especially because I could solve theoretical problems." This experience helped him decide to focus on theoretical (理论的) physics.

Sub-heading 2: ________

Prof. Edward Teller encouraged Yang to turn one of his research ideas into a Ph.D. paper, which explored the concepts of symmetry (对称性). "That became one of the main themes, or perhaps the main theme of my later work," Yang said.

In 1954, Yang worked with Robert Mills to develop the "Yang-Mills theory". This theory is very important and is a key part of the Standard Model of particle physics.

Two years later, Yang collaborated with another University of Chicago alumnus, Tsung-Dao Lee. Together, they conducted groundbreaking research on the "parity laws", which challenged a fundamental belief related to the left-right symmetry in physics. This work was so significant that they were awarded the 1957 Nobel Prize in Physics.

Sub-heading 3: ________

Yang was a brilliant researcher who also made important contributions to other fields like statistical physics. Besides the Nobel Prize, he received many other honors, including the U.S. National Medal of Science.

Throughout his life, Yang remained deeply devoted to China. He worked hard to promote scientific and educational development in the country. He helped build academic exchanges between China and the U.S., and helped establish the Institute for Advanced Study at Tsinghua University. After returning to China from the United States in 2003, he nurtured young scholars at Tsinghua University. In 2015, he gave up his U.S. citizenship and restored his Chinese nationality.

In some ways, "three" is a number that has magical powers. If you are a close observer of life, you should have found that this number is all around us. Everything has a beginning, a middle and an end. We eat three meals a day. Traffic lights all over the world use three colors: red, yellow and green. And there is the rule of three. It is an age-old writing technique. According to this rule, things can always become more satisfying to readers if they come in threes. Did you know that the world's most powerful brands use the rule of three to enhance their marketing? Just do it. I'm loving it. Coke is it. All of these famous slogans are three words long. (And perhaps you have realized that we have only offered three examples. Well, in many articles, examples often come in threes.) (Including this one, it's four).

But what is it about the number three that makes it so magical? Well, we know that the human brain is very complex. However, it enjoys thinking in patterns. It is always trying to find structure in seemingly unrelated information. What's more, if there are no patterns, our brains will create them. And three is the smallest number needed to form a pattern. As the old saying goes, "Once is luck, twice is coincidence and three times is a pattern." Moreover, our brains can only remember a little information at any given moment. An audience member will usually only remember three things from a speech. Do you want something in your presentation to stick in your audience's minds? Put it forward to them in groups of three.

If we properly use the rule of three in our daily lives, we can make many things easier. For example, many people like to add lots of tasks to their to-do lists. Experts, however, suggest they should limit themselves to just three tasks. These top three tasks should be hard enough to be challenging while still being achievable. And the next time you are making New Year's resolutions, consider listing only three things to work on. The longer your list is, ________!
