      You want to know about life in the past. Right? I can tell you. When I was a  boy, things were 

different. I had to get up at six every morning. That was not  very bad in summer, but in winter it was

 cold. And we didn't have any hot water  in the house. We had to wash in cold water. We didn't have

 a bathroom (浴室). My  dad had some chickens. I had to feed (喂养) them every morning and then I

 had to  walk to school with my little sister. It was about two miles (英里) to school and  about two 

miles back in the evening. But it always seemed longer in the morning  when we were going to school. 

There was a bus, but we didn't have any money. And  we had to go to bed at eleven o'clock every 

night because I had too much  homework and housework to do. We couldn't watch TV because there 

wasn't any. On  Sundays we had to go to church (教堂) three times -morning, afternoon and evening. 

And we couldn't play outside on Sundays. But it wasn't all bad. We had some good  times (时光). We 

could go out and our parents didn't have to worry about us. There  weren't so many cars on the roads 

then, so the streets were safe to play in. And  there were not many robbers and thieves in those days. 

We had to work hard and  we weren't able to buy all those things in the shops today. Life was hard, 

but  it was simple (单纯的) and people were happier. I don't think I'd like to be young  today.
