Read the dialogue and do the exercises.

Hi, Lisa. What's it in your hand?

I'm reading this book called Inventions.

Sounds fun. Do you like it?

It is really cool.

Did you know that Graham Bell invented the phone and made the first call in 1876?

He called his assistant and said, Mr. Watson, come here. I want to see you.

I didn't know that. It is really great.

What about space? Did you know that astronauts walked on the moon in 1969 for the first time?

Yes.

And another invention is the computer.

Computers were as big as a room in the beginning.

That's interesting. We have the computer technology in our pockets now thanks to our mobile phones.

We can communicate with people in other countries via the Internet.

Yes, you're right. I also read the history of the Internet.

Tim Berners -Lee invented the World Wide Web in 1989.

I think life was quite boring before the Internet. The developments in science are very important.

We need to thank scientists. They are trying hard to make a difference and improve our lives.
