In 1997, Joe Jacobson was working as a researcher for the Massachusetts Institute of Technology (MIT). One summer, he went on holiday to the coast. He was lying on a beach when he finished his book. Unfortunately, he didn't have another one with him. At that moment, he imagined an electronic book that he could download any time he wanted and read in direct sunlight. It was a 'Eureka' moment.

Thomas Alva Edison

THE LIGHT BULB

A. The electric light, one of the everyday inventions that have great influences on our lives, was not "invented" in the traditional sense. Thomas Alva Edison was neither the first nor the only person trying to invent a light bulb. Twenty three different light bulbs were developed before Edison's. However, Edison is often known as the inventor because his version was better than the earlier versions.

B. Edison was born on 11 February 1847, in Milan, Ohio. He was the youngest of seven children of Samuel and Nancy Edison. His father was a political activist from Canada, while his mother was an accomplished schoolteacher and a major influence in Edison's early life.

C. In 1878, Thomas Edison began serious research into developing a practical lamp. Edison and his lab associates conducted thousands of experiments to develop the electric light bulb. The greatest challenge was to find a material that could serve as a long-lasting filament. By 4 November 1879, he filed a patent for an electric lamp using a carbon filament.

D. This discovery marked the beginning of commercial light bulbs. In 1880, Thomas Edison's company, Edison Electric Light Company, began marketing its new product. Almost every household now owns one light bulb. The invention has put an end to humans' experience of darkness.

4. Read the text again. For questions 1-5, decide if the following statements are true (T), false (F) or not given (NG).

1 Thomas Edison was the first person to invent the light bulb.

2 Edison's light bulb was more advanced than other light bulbs.

3 Edison's father was the most influential person in his life.

4 Edison received his first patent for the light bulb in 1879.

5 Edison's light bulb became a popular product in 1879.

Cleaning the floor is always a laborious and boring task, but with the help of a robotic vacuum, things will be much more convenient. First, robotic vacuums provide humans with a much cleaner environment. Any dust, spots. and dirty marks in the house which may harm owners' health can be cleaned completely. Second, using the mobile application as a remote-control device, house owners can control the robot when they are away from home. Another advantage is that robotic vacuum cleaners are easy to store and easy to carry. A robotic vacuum is usually much smaller than a vacuum cleaner, so it can be easily stored in a closet, under a bed, or anywhere. Last but not least, robotic vacuum cleaners are cost efficient. They are much cheaper than expensive housekeepers. The machine can be set to clean exactly as we wish, while requiring little maintenance. The only job is to replace the bag or empty the container from time to time.

However, I would like to talk about one of those inventions today, the smartphone. To start with, I'll tell you about how it benefits our lives.

We can use them to make both audio and video calls, send messages, read emails, edit photos, and work on various types of documents. Additionally, they can be very helpful in times of need. Imagine travelling on an unknown road and your motorbike breaks down, you can use your smartphone to call a mechanic or a family member. It's also ideal if you are sick or injured and need a doctor. As you can see, there are many benefits of smartphones. Now, let me move on to some disadvantages of this invention.

(1) Cooking is always a laborious task, especially for those who are busy or care for a number of people; however, with the help of an air fryer, things have become more convenient.

(4) Users just need to put ingredients in the fryer and set the cooking temperature and timer. (5) Then ten to twenty minutes later, the food is ready to be served. (6) Another advantage is that air fryers provide humans with healthier meals. (7) Little or even no oil is needed to fry various foods ranging from potatoes to chicken. (8) People, therefore, can avoid consuming deep-fried foods which contain a lot of fat and reduce the risks of many diseases. (9) Last but not least, air fryers are cost-efficient. (10) Instead of buying dozens of cooking appliances, people now only need an air-fryer that not only fries but also heats, roasts, bakes and grills.
