—       my dad        my mom like it. They both like country music.

—It doesn't matter.

—       . After all, you didn't mean it.

    Now, it seems that artificial intelligence(人工智能) is becoming more and more popular in our life, and it has greatly influenced the ways we live, work and play. Can you imagine that you can play table tennis with a robot one day?

    Recently, a scientist has invented a special robot that can be a table tennis coach. That means people can practice table tennis not only with humans but also with a robot.

    Named Forpheus, the smart table tennis robot is quite special. It can study the movements of human players and the speeds of the ball. In this way, it can exactly judge(判断) the players' skill levels(水平).Then it uses the information to change the ways to play. If the players are just beginners, Forpheus will play in a slow and easy way, but if the players are better ones, the robot will play in a faster and more difficult way. What's more，while playing, it encourages players 10 try their best with words like "Good job!" "Come on!" and so on. At the same time, it gives some good advice to improve their sill so it is a good partner and clever coach.

    Science and technology is developing quickly these days and it's hard to imagine what will happen in the future." In the next 20 years, it will be possible that one robot teaches another to play table tennis or even invents another one!" Takuoya, the inventor of the robot, said.

    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 the morning 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. "Good morning, Tom! Your order is in Case 4. Thank you for shopping." When Tom removes his order from Case 4, the trade is 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 have 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.

—Yeah. I didn't know that       I saw the film Born in China.

—       I suppose we shall have a wonderful night!
