[ SRTB ] 009. How Technology Helps People.

Nowadays, we live in an advanced world. We use many new inventions that people long ago never imagined. 

In the past, people could not regularly communicate with others. It took days, weeks, or even months just to send a letter. There were no telephones. So people had to talk face to face. Nowadays, we use cell phones to call anyone anywhere in the world. And we send email to people instantly thanks to the Internet. 

In the past, traveling short distances took a long time. People either walked or rode on a horse. Now, most people own cars. They can drive long distances in short periods of time. And people can even fly around the world on airplanes now. 

In the past, people often died because of poor medical treatment. Even a toothache could sometimes kill a person! Now, vaccines protect people from diseases. And doctors are making more and more discoveries every day.
