When you hear the term computers, it’s difficult to imagine different devices from a laptop or a small desktop. Believe it or not, they weren’t always like they are today. They used to be very large and heavy, sometimes as big as an entire room. Some technology professors historically define computers, as “a device that can help with computations”. The word computation involves counting, calculating, adding, subtracting, etc. The modern definition of a computer is a little wider, because in our day and age, computers store, compile, analyze and compute an enormous amount of information. Ancient computers were very interesting. Actually, the first computer may have been located in Great Britain, at Stonehenge. It is a man-made circle of large stones. Citizens used it to measure the weather and forecast the change of seasons. Some specialists say that another ancient computer is the abacus. It was used by the early Romans, Greeks, and Egyptians to count and calculate. Even though they are no longer in use, certainly, these early devices are fascinating. Computers are embedded in our history and some people say that we are completely dependent of them. No matter the complexity of the task, easy or difficult, some people can’t do anything without them. Do you contest or share this opinion? 

The word “located”, highlighted in the text, has a meaning equivalent to one of the following alternatives, check it.

Why Easter is bad for ducks

      On Christmas Eve, two Pekin ducks were found frozen to a pond in Smithville, Ohio. They flapped their wings and squawked, fruitlessly struggling to free themselves until two locals, Maiara and Helder Bertolucci, spotted them. The pair slid on their stomachs over razor-thin ice and chiseled the animals free.
       The rescued ducks—later named Olaf and Elsa, after characters from Disney’s Frozen—were two of 109 domestic ducks abandoned in a pond outside of a restaurant. A local group ________ Good Sprout Rescue and Sanctuary rescued the animals; two died, but the rest were rehomed to sanctuaries or adopted. Every spring, the Barn Restaurant would buy a hundred new babies for its patrons to enjoy— but since this incident they’ve __________ not to do so again.
         Every year in springtime, particularly at Easter, many people “impulse buy” ducklings as gifts, often for their kids. But after the holiday, sometimes months later, animal rescuers routinely see an uptick in abandoned adult ducks in local parks and ponds, Di Leonardo says. There’s no ________ data on how often this happens, but he estimates tens of thousands of domestic ducks are dumped each year throughout the U.S. His organization rescues as many as 500 ducks per year in the New York City area alone.

Text: The importance of the PowerPoint as a classroom resource
(Text adapted from Teachers: 5 Tips for Creating Great PowerPoint Presentations, retrieved

   PowerPoint is a resource developed by Microsoft and released initially in 1990. It is mainly used in professional meeting presentations all over the world.
    One of these professions is in educational area: teacher.
    PowerPoint presentation is spread among teachers because it is different from lecturing or teaching with a textbook; it is also a way of sharing content with students.
    To produce a PowerPoint correctly, teachers need to know how to put the slides together, it can be an effective way of reinforcing content to students so that they are better able to retain it. Otherwise, teachers can print and distribute the PowerPoint presentation or post it online, so students can go back and access it as reference material. However, if it is not put together correctly, a PowerPoint presentation can disengage and make students bored.
   To develop PowerPoint presentation is simple and it can also provide a fun time noticed by its characteristics: basic, simple, and not distracting, it can be focused on keywords; for instance, always be sure to include a summary slide of what the presentation is intending to accomplish as well as a table of contents on the different topics that will be covered in the program. The summary slide serves as the main topic and what students should learn after viewing the presentation. Then, at the end of the PowerPoint presentation, teachers should include another summary slide, going over everything that was just covered and, again, highlighting the main point.

Bottom line
    PowerPoint presentations need to have a purpose and the teacher must make sure that the purpose is understood.

Add pictures
    Teachers can reinforce the content with pictures, charts, symbols, and other images. In fact, sometimes it’s better to have more pictures than text in a PowerPoint presentation, because images work to reinforce a content main point.
     Teachers typically will just share it with their classes, so they can pull images straight from the Internet. However, for teachers who are making more public and widespread presentations, copyright law needs to be considered (Brazil Information Access Law nº 12.527; Art. 31; paragraph 3; item II). 

Add video
      Pictures can help to reinforce a main point or support content, as well as videos. Some research affirm that students enjoy watching videos and retain information from them well, especially if the video is engaging, interesting and informative. Teachers can embed videos right from YouTube or from their desktops to complement a PowerPoint presentation.

Practice
      Nothing turns off a class like a poorly put together PowerPoint presentation, so teachers should always be sure to do a quick rehearsal before they present it to the class. While testing it, make sure all the images load up on the slides, videos load up properly and audio works, too. Also, it’s important for teachers to make sure that there’s a way to connect their computer, or upload anything that’s storing the PowerPoint presentation, to a larger TV monitor or projector screen so the whole class does not have to huddle around a computer screen to view it. Teachers should also make sure that any text can be read and understood. Be sure that the color scheme is good.

Make it fun
    A PowerPoint presentation can be an innovative way of teaching. It’s a more interesting and engaging way for students to learn than the typical lecture. Teachers should embrace this teaching resource and have fun with it. Throw in some jokes, possibly some funny pictures and be sure to get creative with presentations.

      As we previously noted, the more students enjoy a lecture, presentation, or activity, the more likely they are to retain information.

Artificial General Intelligence Is Not as Imminent as You
Might Think

     To the average person, it must seem as if the field of artificial intelligence is making immense progress. According to the press releases, and some of the more ________ media accounts, OpenAI’s DALL-E 2 can seemingly create spectacular images from any text; another OpenAI system called GPT-3 can talk about just about anything; and a system called Gato that was released in May by DeepMind, a division of Alphabet, seemingly worked well on every task the company could throw at it. One of DeepMind’s highlevel executives even went so far as to brag that in the quest for artificial general intelligence (AGI), AI that has the flexibility and resourcefulness of human intelligence, “The Game is Over!” And Elon Musk said recently that he would be surprised if we didn’t have artificial general intelligence by 2029.
     Don’t be fooled. Machines may someday be as smart as people, and perhaps even smarter, but the game is far from over. There is still an immense amount of work to be done in making machines that truly can comprehend and reason about the world around them. What we really need right now is less posturing and more basic research.
     To be sure, there are indeed some ways in which AI truly is making progress—synthetic images look more and more realistic, and speech recognition can often work in noisy environments—but we are still light-years away from general purpose, human-level AI that can understand the true meanings of articles and videos, or deal with unexpected obstacles and interruptions. We are still stuck on precisely the same challenges that academic scientists having been pointing out for years: getting AI to be reliable and getting it to cope with unusual circumstances.
