    This is a home of the future, a "smart home", where technology can do almost everything. Imagine we are in the year 2050, ①the computer wakes Tom up in themorning as usual. In front of him is a to-do list of the important events for the day, and it is provided by the computer too. According to Tom's request, the computer serves a list of possible dishes. All the dishes are nice.

    As Tom eats breakfast, the computer reminds him to reply to Lucy. Before Tom finishes his next bite, Lucy's computer receives the message. Then Tom goes to the supermarket. The store's system checks his car when he drives to the pickup area and greets him by name. "Good morning, Tom! Your order is in Case4. Thank you for shopping.'' When Tom removes his order from Case 4, all trades are completed automatically(自动地)over the information superhighway. That is, the money is electronically paid into the bank. Soon after arriving at the office, Tom reads another message from Lucy, telling him that she will go to dinner with him.

    The smart home can also do many other things:

    ◆Find things like keys and mobile phones.

    ◆②        (打开或关闭)machines and lights with your voice.

    ◆Clean your home from clothes to buildings automatically.

    ◆Record everything and everyone entering and leaving the house.

    ◆Take care of each member of the family, young or old.

    ③With the development of technology, the smart home will come true in the future. It is sure to play an important part in our life.

    Everyone knows that exercise is important. We all need to exercise. There are many ways to exercise. You can walk, run, swim, skate, or play ball games, but you should remember to exercise in the right ways.

        ①    Before you do any exercise, make sure to warm up for at least five minutes. During warming up, you should extend all parts of your body.

        ②      It's best to exercise twice each week. Thirty minutes each time is enough. Try all kinds of things until you find one, two or even three sports that feel right for you.

        ③    There are a lot of equipments (设备) at fitness centers. The equipments will help exercise your arms, legs and other parts of your body to make you fit. Some people buy equipments for their homes. But it is very expensive.

    We live in the age of the computer. People like scientists, teachers, writers and students use computers to do all kinds of work. But more than 30 years ago, computers couldn't do much. They were very big and expensive. Very few people were interested in them and knew how to use them. Today computers are smaller and cheaper. Since they can do a lot of work, many people like to use them. Many people have them at home.

    Computers become very important because they can work faster than men and make fewer mistakes. Computers can help people do a lot of work. Writers now use computers to write. Teachers use them to teach. Students use them to study and children use them to play games. Computers can also remember what you put into them. Computers are very useful and helpful. They are our good friends. Do you want a computer?
