Have you ever been in a situation where first aid was required? Did you know what to do? Did you feel adequately equipped and confident enough to perform first aid procedures? At the SOS Center, trained professions provide some one-on one and group courses in first aid. 1..
First Aid For Infants (婴儿)
This course is designed for first- time parents who do not have a basic knowledge of first aid for infants and babies, 2., or if you want to avoid more life threatening problems and illnesses, you will get them from these topics.
First Aid for Children
Every parent knows the fear of releasing their small child out into the world, away from their watchful eye. 3.. This course teaches parents how to determine when an injury requires stitches (缝针), how to treat basic cuts, as well as how to treat sunburns and other wounds.
4.
Our most popular course offers all kinds of approaches to applying first aid. In this two-day course, you’ll learn some basic skills such as how to respond when a child or adult chokes, what to do if someone has a heart attack or stroke, how to react to snake bites and spider bites, and more. This course is highly recommended for learners of all ages.
5.. In addition, we are planning to open special courses in community centers around Beijing. For more information on SOS and our course selection or to register for a course, please visit www.firstthigsfirst.com.

Slowly but surely, we’re moving closer and closer to 5G world. From smart-home security to self-driving cars, all the internet-connected devices in your life will be able to talk to each other at lightning-fast speeds with reduced delay, Objectively speaking, the fastest 4G download speeds in the U. S. top out at an average of 19.42 Mbps. But by comparison 5G promises gigabit (千兆) speeds.
“5G is one of those signs, along with artificial intelligence, of this coming data age,” said Steve Koenig, senior director of market research for the Consumer Technology Association. “The self-driving vehicle is a great emblem of this data age, and that is to say, it is a sign of time, because with one single task, driving, you have massive amounts of data coming from the vehicle itself, and a variety of sensors are collecting a lot of information to model its environment as it moves. It’s pulling in data from other vehicles about road conditions down the lane. It could be weather information, but also connected infrastructure (基础设施) construction. There’s lots of data behind that task, which is why we need high speed.
Augmented reality glasses and virtual headset haven’t yet broken the mainstream, but tech companies are joyfully betting that these devices will eventually replace our smartphones. With 5G, that could actually happen. This is notable because companies such as Apple are reportedly developing AR glasses to assist — or perhaps even replace — smartphones.
Ericsson stated at February’s Mobile World Congress how smart glasses could become faster and lighter with a 5G connection, because instead of being weighed down with components, the glasses could rely on hardware for processing power.
But don’t get too excited. There’s still a lot of work to be done in the meantime, including various trials to make sure the radios play nicely with hardware and infrastructure construction so 5G isn’t concentrated only in big cities.
1.What does the author want to stress in Paragraph 1?
A. The lighting-fast speed of 5G.
B. The expectation of 5G world.
C. The difference between 4G and 5G
D. The internet-connected devices in our life.
2.What does the underlined word “emblem” in Paragraph 2 mean?
A. Exhibition. B. Success.
C. Symbol. D. Explanation.
3.We can infer from the text that ________.
A. 5G world won’t come without AR glasses
B. 5G helps to create the artificial intelligence vehicle
C. Apple company is developing AR glasses worldwide
D. Tech companies will face the fact that smartphones may be replaced
4.What will the author probably tell us next?
A. How to fully expand 5G coverage.
B. Smart glasses will become faster and lighter.
C. Why 5G isn’t concentrated in big cities.
D. The importance of infrastructure construction.
Researchers have found bees can do basic mathematics, in a discovery that deepens our understanding of the relationship between brain size and brain power. Recently, A study conducted by researchers from RMIT University in Melbourne, Australia showed that bees could perform arithmetic operations like addition and subtraction (减法).
Solving math problems requires a complex level of involving the mental management of numbers, long-term rules and short-term working memory. The finding that even the tiny brain of a honeybee can grasp basic mathematical operations has a possible effect on the future development of Artificial Intelligence, particularly in improving rapid learning.
RMIT’s Professor Adrian Dyer said numerical (数字的) operations like addition and subtraction are complex because they require two levels of processing. “You need to be able to hold the rules around adding and subtracting in your long-term memory, while mentally using skillfully a set of given numbers in your short-term memory,” Dyer said. “On top of this, our bees also used their short-term memories to solve arithmetic problems, as they learned to recognize plus or minus as abstract concepts.”
The findings suggest that advanced numerical cognition (认知) may be found much more widely in nature among non-human animals than previously suspected.
“If math doesn’t require a massive brain, there might also be new ways for us to include interactions of both long-term rules and working memory in designs to improve rapid AI learning of new problems,” said Dyer.
Many species can understand the difference between quantities and use this to search for food, make decisions and solve problems. But numerical cognition, such as exact number and arithmetic operations, requires a more complex level of processing.
Previous studies have shown some primates (灵长目动物), birds, babies and even spiders can add and/or subtract. The new research, published in Science Advances, adds bees to that list.

Five thousand square meters of old damaged cars, motorcycles and boats fill this junkyard. For a casual onlooker, this might be a very sad sight. But for Andy, it’s a real treasure. “I’ve been a junk hoarder (囤积者) for my whole life and I like fixing up what shouldn’t be thrown away. Around 200 old cars end up in this junkyard every week. Some of them are sold for parts, others get repaired, and still others are beyond repair.”
His father Bobby started the business some 50 years ago and still spends every morning there. The father and son have very different approaches to their work. They got a Dean cab that was getting thrown away and that was the father’s project, which Andy did not want him to do. “He did basically the opposite of everything I told him and I think he did it just to make me mad. He dumped a ton of money into this car, but in the end it wouldn’t run.” Andy said jokingly.
The unusual family business attracted the attention of a TV crew. That’s how the show Janka Empire came to be featured on a network of the Discovery Channel. This show, five years of shooting, five seasons and 60 episodes (集), is popular. “There are hundreds of junkyards throughout the United States. I think what’s interesting is that it is a family business. My father and I started the business and we joke very well back and forth and I think that’s what people like. The cars that end up at the junkyard come out with endless surprises. See, this was a junk car and we restored it with a blown motor. Yet I don’t get a chance to ride around it too often. Because despite its shining appearance, the noise of the engine is truly deafening and I worry my neighbors will not put up with it.”
1.What does Andy seem to like about his junkyard?
A. It is very large.
B. It may be a bad sight.
C. It is amazing and valuable.
D. It is his life dreamland.

A. The father is ready to follow his son’s advice.
B. The son is impatient and fed up with his father.
C. The father and son get on well with each other.
D. The father and son often disagree with each other.
3.Why is the show Janka Empire popular?
