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.

現今，我們生活在一個先進的世界，我們使用許多過去的人從未想像過的新發明。

從前，人們無法經常與彼此溝通，光是送信就要耗時幾天、幾週甚至是幾個月。由於當時沒有電話，人們必須要面對面才能講話。現在，用手機就能打電話給世界上任何角落的任何人，由於有網路，我們能立即傳送電子郵件給他人。

在過去，短程旅行也相當耗時，人們不是走路就是騎馬。而今，大部分的人擁有自己的車，他們可以在短時間內開車到很遠的地方，人們現在甚至能搭乘飛機前往世界各地。

過去人們經常死於醫療的貧乏，甚至連牙痛有時亦能致人於死！如今，疫苗讓人們免於疾病之苦，而且，醫生每天都有越來越多的醫療新發現。
