How often does she use it?

Jerry: OK, so what do you think is the most useful invention then?

Sandra: What, in the world? Yeah, well, that's a difficult question! Hmm, I'm pretty sure I couldn't live without a television!

Jerry: Really?

Sandra: Yes, really! I mean, what would I do after school every day and at the weekends?

Jerry: But television is just entertainment, isn't it? Do you think it's useful?

Sandra: Well, yeah - it means we can learn about major news events. You know, with digital television and 24-hour channels, we can always find out what's happening in the world. Yeah, I think it's really useful. But anyway, what about you then? What invention do you think is the most useful?

Jerry: Hmm ... well, my computer means everything to me.

Sandra: Do you use it a lot?

Jerry: Yes, all the time. Yes, I'd certainly say it's the most useful invention in our house – even more useful than my mobile phone! You know, I do my homework on it, send emails to my friends, and visit websites and chat rooms.

Sandra: Do you have it in your bedroom?

Jerry: Well, no, it's in the study. You see, my mum and dad sometimes use it for work, too. And hey, if it crashes, we all get really annoyed!

Sandra: We haven't got a computer at home, so I don't use one much.

Jerry: Really, I can't imagine life without a computer!

What does Sandra think is the most useful invention?

Read the passage and answer the question.

Over 65 years ago, the world's first computer was "born." Scientists called it "The Baby," but it was huge. It filled an entire room! Three people made the computer and programmed math problems for it. On June 19, 1948, the computer solved its first math problem in 52 minutes! At that time, this was amazing.

Computers are now much smaller. With touch-screen technology, many computers don't need extra things, like a keyboard or a mouse. In the future, computers probably won't need these things at all. Some computers, like the smartphone, can fit in one hand. Computers are also more powerful today. There is more computing power in a smartphone than there was in all of the computers on Apollo 11, the first spacecraft to take people to the moon!

How else will computers change in the future? A computer's "brain" is a chip inside the computer, and in the future, people will definitely be able to save much more information on a computer chip. So, computers will be smaller and even more powerful. Perhaps they'll even think like humans!
