听一分钟英文：Technology-科技

What would we do without technology? Would we still be living in caves? Probably. I think there are two main kinds of technology. The kinds before and after computers. When we think about technology before computers, it was quite basic. It was all mechanical¹. Things like steam trains and fridges. At the time, that was cutting edge² technology. But, today’s technology is really cutting edge. It’s the kind of technology that is out of date as soon as it hits the shelves. I love this. It’s so exciting seeing it all happen. I love reading about what technology we’ll have in the future, and then buy it a few years later. It’s like buying technology from science fiction movies. I’d love to live to be 200 so I can see what technology is around then.
