Unit 5 Power of Ideas Section A 1a-2d 课件2026-2027学年人教版英语九年级上册

How would you like to have a machine that could make anything you wanted? Sounds good, doesn't IT. Well, this is now possible through the magic of 3d printers。And while you might not yet see a freely printer sitting alongside your toaster or your TV at home, you will start to see them more and more in places like schools, in in hospitals and many other places. But what is a fredy printer? And how does three d printing allow us to make almost anything from nothing? Or first, we need to take a step back and look at how we Normally make stuff. Basically, there are four ways we make things. The first way is called subtractive manufacturing. In subtractive manufacturing, we take a lump of material like wood or metal or stone, and we cut away some parts of IT to make the thing we want. So we remove or subtract, just like you doing that material, we don't need to create something. And this could be carving a wooden chair from a tree or making a statue from some stone. The second way of making stuff is called forming. And here we take a block of material, and we apply a force to change its shape. My personal favorite of a formed object is wAllison gromit, made by shaping or forming. The third way we make things is called casting. And this is where you take a solid material and you make IT into a liquid, and you core IT into a mold. And a nice example of casting one of my favorites is the way we make chocolate bunnies and esteros. There's also a fourth way we make stuff, and that is called additive manufacturing. And this is where we have nothing to begin with. And you take your material and you add IT exactly where you want IT until you have your final object. Three d printing is one type of additive manufacturing, and IT involves making an object by adding material, one tiny layer at a time. So how do you do that? Well, IT all starts by making a drawing of the thing you want on your computer. The computer then makes a special kind of file, which IT sends to the 3d printer。And the 3d printer reads that file and prince the object layer by layer to make the thing you want。Sounds interesting, but why would you want to do that? 3d printing can help people to make new shapes and new objects that were not previously possible。And all sorts of different materials can be used like plastics or metals, or food, or even even living cells that your body is made of. So who uses three d printers? Who cares about this? Engineers are using three d printers to make parts of jet lighter and stronger, to make airplanes more efficient and useless fuel. Doctors are using 3d printing timing new hands，arms and legs that are perfectly fitted for the patients who need them. Even shifts are experimenting to make amazing new types of food that you just couldn't even imagine. And hospitals are using three d printers to make new body parts for people such as new bones, to repair really bad fractures, perhaps to the face or to the hand. And even using three d printers to make objects from catholic, the thing that your ear is made of, to make new ears. For people who may have had a bad accident one day, we may even be able to 3d print new organs inside your body，like kidneys or livers, using the patient own cells in these printers. 3d printing is already changing the way we make stuff。And who knows what amazing things that. 让我们看看四位。盲人。用户的实际体验如何。我we. we have here for you, right here for you in living room, Kevin, a veteran ecowas glasses, a . oscuro, a man with dark hair and a beard, is holding a camera, wearing a black t shirt and dark pants in the center. There are right and dark pants. That's a . good description. Most tech hasn't been built for us. And even when in house, I haven't felt fully understood. And the gig, we are changing them. This is Kevin. He's been blind since age fourteen, and he's worked at apple and google. He's now the chief visionary and evAngelist at a giga. I gave myself that title because the blind community has a clear vision of what products like ecover sion should be. Echo vision looks like everyday glasses with buttons on each temple, the left for power photos and video, the right for curing ecover sions AI Kevin hands joe, a blind accessibility expert, the ecover sion classes and live . AIN description mode on the car described this room. What type of video camera? What I Normally will do is I will go as far as I can with our item until I run out of questions and I go a vision got me to run our questions today. That's IT. And now you guys keep calling in a prototype, but I used production glasses that have more hick ups than this. That's empowering to me. This makes me want to take this on my next trip. Kevin hands, marry a blind retirement. The ecology glasses. Mary presses the AI button for person description . a man with short, straight, black hair, eyes that seem focused. You get a lot dates this way. The experience for me as a first time user was that it's fairly instantaneous and giving feedback. I got a pretty good amount of detail about Kevin's face. You're not Kevin hanson. Call a blind student. The ecole sion glasses SHE presses the AI . button for a transit route preview o to mountain transit. everything I need to know to make a decision, and that's what's empowering. IT gives you back the power to make . decisions for your life. Let George presses . the AI button and enters dedicated reading mode. He sits on the couch, holds up a book, and the ecology glasses . read the pages to him. Mayers thirty five acres to the next page. I was able to read a full page. Turn the page, read as good. I haven't thought about physically reading a book in many years. So this opens a new door to something i've give enough.
