Unit3 Computers---Using Language 学案 ‎ ‎【课前预习】‎ ‎（B层）阅读表达 I'm part of an android football team. About once a year we are allowed to get together to play a game of football. I'm as big as a human. In fact, I look like one too. On the football team I'm a striker so I have to be able to run very fast. My computer chips help me to move and think like a human. For example, I have learned to signal to my teammates in computer language to give me the ball when I am open and have a good shot for a goal.‎ ‎ My first football competition was in Nagoya, Japan several years ago. Last year our team went to Seattle, Washington in the USA. We won second place. Personally, I think the team ________________ cheated. They had developed a new type of program just before the competition. So we need to encourage our programmer to improve our intelligence too. We are determined to create an even better system. In a way our programmer is like our coach. She programs us with all the possible moves she has seen while watching human games. Then she prepares reliable moves to use if a new situation arises. In this way I can make up new moves using my "artificial intelligence". I would really like to play against a human team, for I have been programmed to act just like them. After all, with the help of my electronic brain which never forgets anything, using my intelligence is what I'm all about!‎ ‎1.
