Inventions are very important and they can easily change our life. The following are some great inventions.

The television was invented in 1926. As time passed, more and more people were able to buy the television. It is a popular invention, but it is also bad for your eyes. People spend almost 4-8 hours in front of a TV. So they spend less time staying with family.

The plane is a very popular way of going out either for traveling or business. Over 3,000,000 people take a plane every day. It is very convenient for us. And it makes our trip faster and more comfortable. But the biggest problem led by the planes is the air pollution.

Credit cards allow people to buy things first and pay for them later. What’s more, you don’t have to carry lots of money around. However, you may not know how much money you have spent until you get your bill. This might put many young people and families into an economic crisis (經濟危機).

The pacemaker (心臟起搏器) saves many people’s lives. It was an invention that was designed to give the heart small “shocks” and make it work again. The only disadvantage for most people is that it costs a lot of money. Getting one can cost from 16,500 yuan to 35,000 yuan.
