Endless queues and long waits at the ticket inspection desks at China’s major train stations were signature of the Spring Festival travel rush before this year. Every year, as the country’s biggest national holiday unfolded a huge flow of travelers would leave staff at the check-in desks facing a dilemma.
But with the installment (安装) of artificial intelligence (AI) in dozens of train stations this year, including a facial recognition system which is able to process passenger identification within five seconds and therefore speed up the waiting process, busy scenes started to become something of the past.
When a passenger approaches the camera inside the facial recognition system at the station, it scans his face and then quickly compares it with the photograph shown on his identification card in real time. If the information matches, the barrier gates will open and allow the passenger to go through.
Such use of facial recognition technology is in line with discussions heard at the recent two sessions meeting, a key annual political event, which focused on the widespread application of a security network named Tianwang (“Sky Net” in English) currently being used by China’s public security department.
The network, according to reports by the People Daily, has the potential to recognize the facial features of anyone in the world and match them on the spot with photographs on a database of criminal suspects. In fact, it can analyze photographic identity so quickly that it can scan every single Chinese face on the planet in just one second, and it would only take two seconds to scan every face in the world, with an accuracy rate of up to 99.8 percent.
Those are just two examples that highlight the development of Chinese visual AI technology, which industry insiders predict could contribute to powerful growth in the global technology sector this year.

Both honeybees and ants are social insects that live in groups called colonies. They survive by means of their collective intelligence. Their decision-making power is distributed throughout the group; that is, no one ant or bee makes decisions for the group. Instead, they work together. As Deborah M. Gordon, a biologist of Stanford University, says, “Ants aren’t smart. Ant colonies are.” The same is true for bee colonies. Although bees and ants are quite different physically, they have a lot in common in terms of their behavior. Specifically, honeybees and ants have similar roles within the colony, both have communication systems, and both have the capacity of learning.
Ants communicate by using chemicals called pheromones, which can alert others to danger or to a food source. For example, when worker ants find a promising source, they let the rest of colony know how to find it by leaving a trail of pheromones on the way back to the colony. The other ants pick up the message using their sense of smell. Bees, on the other hand, use movement to communicate with each other. Worker bees send message to each other by means of a “dance”. Different speeds and movements send different messages. For example, when worker bees called scouts go out to find a new hoe for the colony, they return and do a dance for the other worker bees that indicates the location of the new home and how suitable it is. The faster the scouts dance the better the new location is.
Honeybees and ants are both capable of learning. One Chinese study found that bees can be trained to learn and remember a route to a food source. The researchers also found that bees can be taught to recognize hidden objects and use the concepts of “sameness” and “difference” to accomplish certain tasks. Ants take this one step further. Recent America research has shown that ants not only have the ability to learn, but also can teach their foraging skills to other younger ants. They observed that older ants accompany young ants in search of food and teach them the route and how to avoid obstacles.
As we can see, the social behavior of honeybees and ants is quite similar. Both coordinate complex actions and accomplish crucial survival tasks by cooperating in groups consisting of many individuals. Unintelligent as they may be as individuals, as groups they often show amazing brilliance as they go about their everyday activities.
1.What do ants and bees have in common?
A. They make use of collective intelligence.
B. They live in similar-sized colonies.
C. They have small leadership groups that make all decisions.
D. They use the same method to communicate with each other.
2.What docs the speed of a bee’s dance indicate?
A. The distance to a neighboring colony.
B. The quality of a new colony location.
C. The discovery of a new food source.
D. The direction to a potential food source.
3.In paragraph 3, how docs the author demonstrate the idea that Honeybees and ants are both capable of learning?
A. By using statistics. B. By explaining reason.
C. By presenting study findings. D. By stating opinions.
4.What does the underlined part “foraging skills” refer to in the third Paragraph?
A. The skills of communicating. B. The skills of sacking food.
C. The skills of leaning. D. The skills of finding a new home.
This story happened when I was in Saint Lucia with my family. My sister, Diane, who also happens to be my best friend and one of the funniest and kindest people I know, went blind in one eye about 9 years ago. Diana sometimes feels concerned about the way her eve look now. The pupil (瞳孔) is no longer black; it’s sort of “glows” in photos. Diana recently purchased a special contact lens (隐形镜片) that makes her eye look like it did before it changed color, but she doesn’t wear this lens often because it becomes quite painful after about an hour.
One night during our holiday, a hotel photographer was taking pictures of the guests as they entered the area set up for dinner. Diana casually said if she had known there was going to be pictures taken to capture this special memory, she would have worn her contact lens so her eye wouldn’t be so shiny in the picture.
The next day, I was sitting with Diana and her husband Ted. While we were talking, the photographer who had been at the dinner the night before, handed her a photo, leaned in and quietly said, “I matched the color of your eyes in the picture.”
As he walked away, my sister happily said to me and Ted, “Look! He fixed my eye!” The photographer stopped. He turned around and walked back to our table. He put his hand on Diana’s shoulder, leaned in again and gently said, “Just to be clear: I didn’t fix your eye. There isn’t anything wrong with your eye. I simply matched the color.” Her eyes filled up with tears. It was very healing for: her heart to hear these beautiful words. It didn’t take much time but made so much difference. It helped her change the way she feels about herself.
I have always loved the quote: “The world is full of good people. If you can’1 find one, be one!” Your acts of kindness can impact the world in pro found ways!

Dear Li Hua,
How are you doing these days? I’m having some problems and would like to get your advice.
My parents want me to spend my summer with them this year but I would prefer to go somewhere with my friends. I love my parents but sometimes they are overprotective. I feel that I am old enough and responsible enough to go away without their supervision(监护).
Any suggestions you could give me about this issue would be greatly appreciated.

The summer job is a tradition among American university students. Long after the end of the school year, students start their summer vacation job search. They send letters to businesses, going to job interviews, and ask our friends and relatives for help. By June the students usually have been found their jobs and then they begin preparing to enter the world of works.
Reasons for wanting a summer job differs from student to student. Some work help pay their school expenses, others work to gain experience in their chosen professions and still others work just for the funny of it. Salesmen or waiters are two of the more common jobs that students try to find during the summer months.
