Fangfang, from Liaoning, just became a high school student last September. She gets up at 5:30 am every day and goes to bed at about midnight. Fangfang feels s1. all the time. “I want to go to sleep early but I have to finish all my schoolwork first,” she said. March 16 is World Sleep Day.

Sleep is like food for the brain. Sleep helps the body and brain grow and d2.. Adults need seven to nine hours of sleep every night. For students aged 10 to 17, a healthy amount is about eight to nine hours per night. But many students don't get enough sleep because of early school start times and h3. homework.

The loveliest house that I have ever lived in was one that my grandparents owned. This house was called Crosslands. I lived there when I was a child. I had some very happy times at Crosslands. It seemed so big to me as a child. It had a big beautiful living room with a piano in it and a large hall. There was a mysterious drawing room which we only used on Sundays or on special occasions.

I used to be amazed by this room because it had the best furniture in it, but it was covered up with sheets(床单). It was as if all the furniture was wearing clothes and it seemed ridiculous to me that we couldn't enjoy this lovely furniture all week long.

The kitchen had lovely red floor, which was always polished, and one big heater to heat the whole room so it was always warm. There was also kind of clotheshorse(晒衣架) above it that we used to hang all our stuff on, and it was just lovely. It was a very warm room and my grandmother used to make ice cream that we'd eat there.

I spent a lot of time in the vegetable garden picking peas and eating them. My grandmother used to get really angry with me because I would pick all the vegetables and fruit for dinner, but eat half of it before she could start cooking. The homegrown food tasted so fresh and delicious. I went back to Crosslands a few years ago but it turned out to be a big mistake. They've modernized the house and gotten rid of those lovely old fireplaces. They've also knocked wall down so the drawing room and living room have become one big, modern room. I think the house has become smaller and my memory of this lovely, large, warm, comfortable house was completely different.

It taught me a valuable lesson: ________________________________________.
