Artificial intelligence（人工智能） or AI for short， is the science of giving computers and machines ability to think and work like humans． AI scientists and engineers have made a lot of cool technologies．
AI is rapidly catching up with the human ability to read faces．As a result， facial recognition（ 识别） is used a lot in the world． Chinese police use this technology to check people' s information．
AI is also used in self﹣driving cars， which are believed to be the future of driving．
Most drivers may wave or nod at passers﹣by to let them cross the street， but self﹣driving cars don't have this ability． Car makers are testing a light signal system to help them "speak" to humans． The system can show what self﹣driving cars will do．
Service Robots also show you how powerful AI is． Imagine this ﹣ you come back home from school and your robot housekeeper is waiting for you at the door．After dinner， he teaches you to play the piano，just like a real music teacher． Such thoughts will soon happen in the real word． In the future， more and more service robots will become good home helpers．
AI is so powerful that it can help human beings and even replace us in many jobs．

American English is full of colorful expressions. One such expression is to touch all bases.
There are four bases in baseball – first， second， third and home plate. When a baseball player hits the ball， he must run to each base – in order – and touch it with his foot. It is the only way to get a point. If the player hits the ball and fails to touch all the bases， the point will not be counted.
The importance of touching all the bases was shown at the start of the 1974 baseball seasons.
Hank Aaron was a player with the Atlanta Braves team. He was trying to find the record for hitting the most home runs (全垒打). Aaron needed just one home run to be well matched with the record held by Babe Ruth， the greatest hitter in baseball history. Aaron got that home run the very first time he had a chance to hit the ball. That gave him 714 home runs – the same as Babe Ruth. After that day， baseball fans held their breath every time when it was Hank Aaron’s turn to hit. When would he hit home run number 715?
The wait was not long. In the second week of the season， Aaron again hit the ball over the wall. He had beaten Babe Ruth’s record. But first， he had to run around the four bases. The other players on his team watched carefully to make sure he touched each one.
So， to touch all bases means to do what is necessary to complete an activity.

One Friday, 12-year-old Janet and her friend Amy had to walk past Mr. Dawson’s house. When Janet saw him, she suggested crossing the street to the other side. But Amy said they needn’t.
When Mr. Dawson saw Amy, he smiled and said, “Hello, Amy! I see you have a new friend with you today.” Amy smiled back and told him that Janet would stay with her that night. Mr. Dawson looked friendly and gave them each a fresh apple. The girls were glad to get them.
Later Janet asked Amy, “Everyone says he is the most unwelcome person in town. Why was he so kind to us?” Amy explained that when she first walked past his house, she was also afraid of him. But she pretended(假装) there was an invisible (看不见的) smile on his face and so she always smiled back at him. It took a long time, but one day he half-smiled back at her, and then started talking to her.
“An invisible smile?” Janet was puzzled. “Yes,” answered Amy, “My grandma told me to think so. She says smiles can run around. If we keep smiling at someone, sooner or later he will really smile back.”
