安徽省黟县中学2019-2020学年高一上学期英语期中考试试卷
Alexa is a form of artificial intelligence, or Al for short. Many people start their mornings by asking Alexa for the weather forecast or the latest news. A device (设备)that houses Alexa can also play music from your favorite playlists, keep a shopping list, order takeout food, answer questions, send voice messages and even run "smart" home controls.
Training AI systems to respond to problems with human-like intelligence—and learn from their mistakes —can take months, or even years. Consider Alexa and similar software, such as Apples Siri. To do the tasks its human owners ask, these systems must make sense of and then respond to sentences such as, "Alexa, play my Ed Sheeran playlist" or "Siri , what is the capital of India?"
Computers can't understand language as it is spoken by people. So AI researchers must find a way to help humans communicate with computers. The technology used to get computers to "understand" human speech or text is known as natural language processing. By natural language, computer scientists refer to the way people naturally talk or write. To teach an AI system a task like comprehending a sentence or responding to a person's last move in a board game, scientists need to feed it lots of examples.
AlphaGO is an AI system designed by Google that has beaten a human champion, Lee Sedol, at the strategy(策略)board game Go. To train AlphaGo, Google had to show it 30 million Go moves that people had made while playing the game. Then AlphaGo used what it learned to analyze those plays as it played against different versions (版本)of itself. During this practice, the program came up with new moves —ones never seen in games between people.
Computers, software and devices that are powered by AI can do much more, however, than just play board games and music. And one day they could make our life much easier and much more interesting.
Memorandum(备忘录) To: Members of all departments From: Annette Derringer Subject: Year-end party Date: November 26 |
This is just a quick note to let you all know the arrangements for next month's year-end party. As you know, the party will be held at the Green Vale Country Club, which we have reserved between 6:00 pm and 10:00 pm on the evening of December 21st. 1 have received replies from almost all of you confirming attendance, but if you have not let me know yet, please do so in the next day or two. Tickets for all employees have been covered by the company. The manager of Green Vale has asked me to explain one or two things to those of you who have not been there before. Basically, there is enough parking space for only 100 vehicles, so he would like to ask those of you planning to drive to try car pool(拼车)as much as possible. Also, the number of lockers available is small, so guests should try to keep belongings to a ,minimum. Thanks in advance, Annette |
To: Annette Derringer aderringer@belway.com From: Kype Berwick Subject: Year-end party Date: November 28 |
Annette, I will be able to attend the year-end party at the Green Vale Country Club on December 21st although I do not think I will be able to arrive before 7:30. I was wondering if it would also be possible to bring a couple of guests. I know it is a bit of a last-minute request, but my brother and his wife are planning to visit us at that time, and they would love to see the Green Vale. If it is not a problem, then could you let me know how much I should pay for their tickets? Also, assuming this is OK, we are planning to drive down in a single car to reduce the need for paring and also to allow us to keep our belongings in the ear. I will have a couple of days off before the party, and I will not be in my office December 17th, so could you get back to me before then? Thanks a lot, Kyle |
