It’s hard to believe that no one had computers a few years ago. I wonder how people lived. There must have been a lot of paperwork. I can’t imagine writing everything by hand. I also wonder how everything worked without computers. We need computers today for everything. Hospitals, airports, the police… nothing can work without computers. I’m sure I’d be ten times busier than now if I didn’t have a computer. Imagine having to find a piece of paper and an envelope and then walking down the street to mail a letter! I love my computer. It makes everything in my life so convenient（电脑让生活中的一切都变得十分方便）. Sure, it freezes and crashes sometimes. Sure I lose some data. But that’s not often. Most of the time my computer is like my best friend.
