David。 Now I’ll take you to the future world—the world of two thousands and twenty。
Our life in two thousands and twenty is technological life。
I’ll introduce something to you not as same as 2008 ‘life —such as cloth, food and house。
First, let me tell about cloth。
In two thousands and twenty, I wear only a coat all of the year。 When the weather is cold, it makes heat。 When the weather is hot, it makes me feeling cool。
In winter, this coat is simpler than before。 In summer, this coat is easier than before, too。 It can work in the sea。 It also can work in the sky。
I do not wash the coat, because it cleans itself。 Why the coat does not need wash and clean? There are two useful materials, carbon and the technology of nm。
When you wear this cloth, you will save a lot of time, water and money。
Next, let me tell about food。 The food is nutrient, you eat this food everyday, and you will not die。
Food is not difficult to the people。 For example every city has a big restaurant。 It is in the centre of the city。 There are lots of robots and scientists in the restaurant。
Scientists make the menu and robots cook。 When you want eat something, you can call the telephone number of restaurant, robots will take the food to your home, office and school。
It is in ten minutes。 The food in the restaurant is cleaner, more delicious and more scientific。 There are not KFC and McDonalds any more, because it is bad to your healthy。
Then let me tell about house。 House is intelligent。 When you go to the home, the robot will open the door for me。
But when a thief goes to my home, the robot will call the telephone number of police station, and PK with the thief。 When I have a question, I only need speak to the house。
For example, I speak ‘one plus one’; the house will say ‘two’。 The house is not bad to the environment。 Because it is made by rubbish, lots of ‘useful’ rubbish。
The house can keep the temperature on suitable level。 In the winter, in the house it is warm。 It not needs grate。 In the summer, in the house it is cool。
It not needs fans。
This is the two thousands and twenty’s life in my dream。
This is the end。 Thanks。
