I am Frank. In our western countries, there are four seasons or 365 days in a year. Usually, we sleep 8 hours every day. So we have 122 days for sleeping. Then our study or work time is only 243 days left. But there are 52 weekends in a year. Each weekend is two days. We lose another 104 days a year for work. It takes up about one hour to have breakfast and supper. This comes to 15 days over a year. Four free hours each evening takes up 61 days. But we can't work all the time, so we need holidays. We have to remember that we get 2 days' holiday at Easter, 3 at Christmas and 1at the New Year. There are also 4 Bank holidays. Take those 10 days away and we have 32 days for work. But then we have one and a half hours' lunch every day, and half an hour's coffee break. That comes to 30 days a year. This means that we have only a few days left for study or work every year. What about you in China?

    I started playing the piano when I was about eight or nine. But when I got to university, I stopped playing it. I just didn't have enough time and there were so many other things to do.

    When I was little, I thought I should play the guitar like my dad. But later I decided to try something else. I chose the violin. I want to be a musician when I grow up, but my dad says it's difficult to make a living from music. But I don't want to be a doctor like him. It's so boring.

    Nobody likes living near someone like me because when I practice, I make a lot of noise! I''m sorry for that but I have to keep practicing. I have drum lessons every Wednesday and Saturday afternoon, and I practice the drums every evening. I love playing them and now I play in a fantastic band.

    I''ve played the guitar as long as I can remember. I used to play in a subway station to make some money. Now I keep on playing it when I'm free, but I work as a cook in a restaurant to make a living.

Life in the future will be different from life today. Many changes will happen. But what will the changes be?

The population (人口) is growing fast. There will be more people in the world and most of them will live longer than people live now. 

Computers will be much smaller and more useful, and there will be at least one in every home. And computer studies will be one of the important subjects in school then. People will work fewer hours than they do now and they will have more free time for sports, watching TV and travelling. Travelling will be much cheaper and easier. 

There will be changes in our food, too. More land will be used for building new towns and houses for all the people. Then there will be less room for cows and sheep, so meat will be more expensive. Maybe no one will eat it every day. Instead (相反), they will eat more fruit and vegetables. Maybe people will be healthier. Work in the future will be different, too. Robots will do dangerous and hard work. Because of this, many people will not have enough (足够的) work to do. This will be a problem. 

① A survey(调查) has shown that lots of people can't sleep well. Sometimes you feel tired when you wake up. You may have a headache and you feel like you could sleep for another three hours. Many things around us cause sleeplessness. Here are a few changes you can make to improve your sleep.

②Go to bed and get up at the same time. You may share the same bedroom with your sister or brother. You both must go to bed regularly(规律地) so that you don't trouble each other.

③Clean up your bedroom. A study from a university in Zhengzhou found that people with clean bedrooms usually sleep better than those with dirty and untidy rooms.

④ Get more house plants. Studies show that house plants help with reducing (减轻)stress. Also, plants such as lavender(薰衣草) and gardenias(栀子花) have smells that may help some people relax and sleep better.

⑤ Make your room dark. When light hits your eyes, it tell you not to fall asleep. In fact, we need darkness especially in the evening. So if you want your body to know that it's time to rest, turn off the lights about an hour before bedtime or wear eye masks. Your phone and your TV should also be thought of. You may also use the dark curtaıns(窗帘) to keep any outside light from going into your bedroom.

⑥Lower your bedroom temperature. The body becomes cooler at night, so lowering the temperature before bedtime can help you relax and fall asleep more quickly. The NationalSleep Foundation in a country says your bedroom should be about 16 ℃ to 19℃ for a good night's sleep.
