STEM Inventions with LittleBits
In this invention workshop, students enhance their skills with a great new system of discovery called LittleBits. It’s a platform of easy-to-use electronic building blocks that empower you to invent anything, from your own remote controlled car, to a smart home device. Students will begin with several inventions designed to let them figure out how the components go together, and then they will design and create their own inventions. Ages 7—12. Introduction to Computer Animation
In this new program, you will have fun designing and creating your own videos. Students will learn the basic skills needed to create and animate. Whether you are making a LEGO brick film, animating in claymation（黏土动画） or capturing a flower bloom, you can bring anything to life with computer animation. Ages 7—12.

I have come to southern Florida to see how licensed local snake hunters are helping the government cope with the recent explosion of invasive Burmese pythons (缅甸蟒蛇) that is destroying the region’s wildlife by eating almost everything—from squirrels to rabbits to foxes—in their path.
Thirty years ago, there were no Burmese pythons in Florida. Now most experts agree there may be as many as 100,000 to 200,000. And they’re reproducing at an alarming rate. The government has to pay to catch and kill the powerful snakes, which can grow to be 20 feet long, as thick as a telephone pole, and weigh over 200 pounds.
I’m with Tom Rahill, a python hunter, who has caught over 500 of the snakes over the last decade and become known as “the snake whisperer” for his success. As we walk along the river bank, I watch Rahill occasionally push a stick into the thick grass. As he looks for more signs, he tells me his stories and about special living habits of snakes.

Suddenly Rahill shouts, “SNAKE! There, slowly crossing the limestone road, is a
Burmese python.” He rushes to the snake. It looks like a five-to-six-footer. Its thick, full belly indicates it must have killed and eaten recently.
Expertly, Rahill moves around the snake as it strikes out at him. He then grabs it with one hand firmly behind its head. I grab its tail firmly as the snake tries hard to wrestle itself away from me. Then, just as Rahill predicted, it poops (排便) all over me.
My pants are covered with smelly Burmese python poop. But I don’t care. We’ve finally bagged our python. Rahill and I high-five each other. He asks me if I want to keep hunting. I quickly tell him, “Let’s go!” As Rahill puts it, there are a lot more pythons out there. 4. Why does the government pay to catch and kill Burmese pythons? A. Because few people dare to catch Burmese pythons.
B. Because Burmese pythons break the region’s ecological balance. C. Because Burmese pythons are difficult to catch. D. Because Burmese pythons are dangerous to people. 5. What do we know about Tom Rahill? A. He is a licensed python hunter. B. He is good at telling stories. C. He knows how to speak to snakes. D. He caught 500 pythons last year.
6. How does the author feel about hunting pythons with Rahill? A. Guilty.
B. Disappointed.
C. Funny.
D. Excited.
7. What does the author mainly tell us in this text?
A. The dangerous situation of the wildlife in southern Florida. B. The endangered Burmese python in southern Florida.
C. An experience of hunting the ecology-threatening Burmese pythons. D. An experienced python hunter —Tom Rahill.

You’ve probably heard that brick-and-mortar retail (实体零售) is in trouble. Even industry giants are closing hundreds of stores. Given retail’s gradual change to mobile and e-commerce (电子商务), you may be wondering, “What will retail look like in the future?” Nobody knows. But here are a few things you can expect to see based on current technology.

Ultrafast delivery is coming. Today, the normal practice is two-day delivery. But if you’ve
been paying attention, you know that’s changing. In fact, a surprisingly high 25% of consumers said that they would abandon their orders if one-day delivery wasn’t available. Of course, that’s just the beginning. Two-hour delivery is coming in the foreseeable future, and Amazon has already been trying 30-minute delivery.
Your kitchen will resupply itself. You won’t have to worry about running out of essentials like coffee, pet food or snacks because your containers will sense stock (库存) levels and replace those items without you having to lift a finger. No more waking up to find your coffee store is empty or last-minute trips to the grocery store because you forgot to buy pet food.
Know exactly what’s in stock and where. Have you ever gone to a store hoping to buy something, only to learn that they were out of stock? A new feature from Google Home allows people to ask Google Assistants to find in-stock products at the closest store. For example: “Google, where can I find the Nintendo Switch console?” An assistant will tell you how many stores have it right then and how close they are. Of course, it isn’t currently available for all stores in all locations, but you can already see a future when it has become standard.
Convenience, experience, and options—retail will take on a new look. 8. How does the author develop the passage? A. By asking and answering. B. By clarifying and describing. C. By analyzing and commenting. D. By comparing and concluding. 9. What can we know from paragraph 2?
A. Consumers can’t get their orders in one day now.
B. It is possible to deliver goods within two hours in the future. C. The delivery will be in two days in the future. D. Superfast delivery has widely been used now.
10. According to the passage, what will happen in the future? A. Retail will disappear gradually.
B. Industrial giants will rule the whole retail trade. C. Shopping will be more convenient and effective. D. People will ask Google Assistants to purchase goods. 11. What’s the best title of the passage? A. What will retail be like in the future?

B. How will new technology change the world? C. How will we run the retail trade in the future? D. What benefits will high-tech bring in the future?

Scientists have discovered a new material that can hold the key to unlocking the potential As the world looks towards a gradual move away from fossil-fuel-powered cars and trucks, of hydrogen-powered(氢动力) vehicles.
greener alternative technologies are being explored, such as electric-battery-powered vehicles. Another “green” technology with great potential is hydrogen power. However, the major obstacles have been the size, complexity, and expense of the fuel systems—until now.
An international team of researchers, led by Professor David Antonelli of Lancaster University, has discovered a new material that offers a solution. The new material would be used to make molecular sieves(分子过滤器) within fuel tanks—which can store the hydrogen and work alongside fuel cells in a hydrogen-powered “system”. It makes the design of tanks far smaller, cheaper, more convenient and energy-denser than existing hydrogen fuel technologies, and significantly outperform battery-powered vehicles.
The cost of manufacturing this new material is so low, and the energy density it can store is so much higher, that the hydrogen fuel cell systems cost five times less than ordinary batteries as well as providing a much longer range—potentially enabling journeys up to around four or five times longer between fill-ups.
The new material makes the cooling system unnecessary. This is crucial because it means cooling equipment does not need to be used in vehicles, resulting in systems with the potential to be far more efficient than existing designs.
Although vehicles, including cars and heavy goods vehicles, are the most obvious application, this material can also be used in portable devices such as drones or within mobile chargers so people could go on week-long camping trips without having to recharge their devices. It could also be used to run a house or a remote neighborhood off a fuel cell. 12. What can we infer from paragraph 2? A. Fossil fuel will soon run out. B. It is impossible to conserve fossil fuel. C. Electric cars will replace gasoline cars. D. It is not economical to use hydrogen power now.
