GUESS THE INVENTION
This invention has no single ‘inventor’, 
but evolved after the development of 
computers in the 1950s.
Since then, it has facilitated many 
technological platforms like e-mail, 
instant messaging, video calls, etc.
In the past, people preserved things by cooling
them in snow or lathering on chemicals like salt.
But this kitchen appliance is so convenient and efficient at preserving perishables that nearly 100% 
of households in America own at least one of it.
Invented by Alexander Graham Bell 
some 150 years ago, many have claimed 
that they can't live without one today.
Of course, modern day versions have since 
been improved to offer better and more 
efficient communication between people.
Although widely associated with Thomas Edison, many other scientists before and after his time contributed to this revolutionary invention. 
To date, this invention has branched off into many different types that illuminate nearly every building, room, and home.
READING PRACTICE
Our lives _______ (make) better everyday thanks to inventions. However, sometimes inventions can make our lives worse. This can happen when an invention _______ (not use) according to the inventor’s plans. For example, Albert Nobel, a Swedish scientist, invented a strong explosive in 1867. It ______ (call) dynamite and it revolutionized the world of engineering. After its inventions, many tunnels, bridges, and other structures ______ (build) with the help of dynamite. However, dynamite _____ (also, use) to kill people in wars. This upset Nobel. Before his death, Nobel used the money from his famous invention to make the world a better place. A special fund ____ (start) in Nobel’s name. Every year, Nobel prizes ____ (give) for extraordinary work in Science, Medicine, Literature and the promotion of the world’s peace.

Our lives are made better everyday thanks to inventions. However, sometimes inventions can make our lives worse. This can happen when an invention is not used according to the inventor’s plans. For example, Albert Nobel, a Swedish scientist, invented a strong explosive in 1867. It was called dynamite and it revolutionized the world of engineering. After its inventions, many tunnels, bridges, and other structures were built with the help of dynamite. However, dynamite was also used to kill people in wars. This upset Nobel. Before his death, Nobel used the money from his famous invention to make the world a better place. A special fund was started in Nobel’s name. Every year, Nobel prizes are given for extraordinary work in Science, Medicine, Literature and the promotion of the world’s peace.
