He liked to explore the World Wide Web and used the Internet to communicate with computer programmers all over the world. When he went to university he studied IT (information technology)and developed a special interest in artificial intelligence. After developing special applications of the computer, he hopes to design an intelligent robot which can think logically and look like a human being, but in reality he has a long way to go.

高中英语必修二：Unit+3+Computers+教案1+
Unit 3 ComputersI. Teaching Material Analysis (教材分析):This text is an exposition on science, whose title WHO AM I? is so interesting that it can arouse students’ curiosity to read. Words and expressions in this text are too obscure to understand. We can use pictures and the context to guide students to understand. There are three paragraphs in this text, each of which has a clear topic sentence that gives the main idea of the paragraph, so students should be guided to pay attention to them. Unlike other expositions, this text is written in time order and the first person, which should be introduced to students as well.II. Students Analysis（学情分析）：It is the first time that students have read an exposition on science in senior school. They are not familiar with this type of writing. In addition, difficult terms and dull content in this text make it boring for students to read. Therefore, it is very important to arouse their interests and gain their confidence in reading.III. Teaching Aims（教学目标）:Knowledge aims（知识目标）：1. Get the students to know the following new words and expressions in this text: calculating machine, universal machine, analytical machine, artificial, intelligence, PC(personal computer), tube, transistor, chip,application, finance, trade, mobile, rocket, network.2. Get the students to have a better understanding of the history and basic knowledge of computers.Ability aims（技能目标）:1. Students can improve their reading ability by predicting, skimming and scanning.3. Students can find the topic sentence and supporting details of each paragraph.Emotional aims（情感目标）:Get the students to be interested in learning computers and learn how to use computers correctly.IV. Teaching Important Points and Difficult Points（教学重难点）: Important points（重点）：1) Enable the students to better understand the text structure by the clues of time;2) Enable the students to find the topic sentence of each paragraph;3) Enable them to improve their reading ability by predicting, skimming and scanning;Difficult points（难点）:1) Enable the students to have a clear mind about the topic sentence and the supporting details.2) Enable the students to explore, discuss and summarize the textstructure.V. Teaching Methods（教学方法）:1. Task-based teaching and learning2. Cooperative learning3. DiscussionVI. Teaching Procedures（教学过程）:Step one: lead-in（导入）To introduce the topic of this unit, ask the following questions:“What do you do in your spare time?”“Do you play games on computers?”Computers are very useful in our daily life.Step two: warming-up（热身）1)“Then in what other ways are computers used?”With this question, we can introduce some words which appear in the third paragraph: communication, trade, science and technology.2) Now that computers are important and useful in our life, then do you know “how computers developed?”It is very necessary that we ask students this question and then explain it to them. In this way, we can help students understand some difficult words which will hinder them from reading, and make them focus more on reading instead of on solving difficult words.From the above tasks, students have already been familiar with the textthey will read, and thus they may not be afraid to read it.Step three: predicting（预测）“Acco rding to the title and the two pictures on page 18, can you predict what will the text be about?”Before prediction, we can ask students to describe the two pictures, which can increase the efficiency of their predicting.Step four: skimming（略读）Ask students to skim the text and then answer the two questions:1) Who is the speaker?Based on prediction, this question is easy for Ss to answer.2) What is the main idea of the text?To simplify the question, I ask them to get the main idea in the following way:The text is about the ________ and the __________of computers. These two questions can help students have a general understanding about the text.Step five : scanning（扫读）Scan the text by listening to the tape and then finish the timeline:In 1642 calculating machineIn 1882 analytical machineIn 1936 universal machineIn the 1940s as large as a roomIn the 1960s connected by a networkIn the 1970s new applicationsNow computers connect people all over the worldFrom this question, students can have a detailed understanding about the text and it will help students clearly find that the text is written in time order.Step six: careful-reading（细读）1) Please read the text for a third time and then find the topic sentence of each paragraph.First read paragraph one in two minutes and find its topic sentence.Students have known how to find a topic sentence of a paragraph, however, they still have no idea about the relationship between topic sentence and supportive sentences in a paragraph. For paragraph one, I will give guidance, and para.2 and 3 can be left to them.2) Now it’s your turn to finish para.2 and 3 in three minutes. After that, have a discussion in groups of four to exchange your ideas.By cooperative discussion, students who have known the topic sentence and supportive sentences may help those who do not know. Step seven: post-reading（读后）The above reading activities are all about input, and now it is high time they should output what they have learned in this text. So I designed a retelling as follows:1) Over time I have been ______ quite a lot. I began as a __________machine in 1642. In 1882 I was built as an _________ machine and then in 1936 Alan Turing wrote a book about how I could be made to be a _________ machine. These changes only became possible as my _______ improved. In the 1960s they give me a family connected by a _______. In the 1970s many new _________ have been found for me. My goal is to provide humans with a life of _____ ______. Now I am a devoted friend and ______ of the human race.Besides language output, I also design a summary about text structure to raise their awareness of a whole text.2) The text was written in _____ order and used_______ person(人称)in _______ and ________________tense(时态).The type of writing (文体) of this text was an ________.Step eight: homework assignment（作业布置）1) Read the text by listening to the tape and underline the difficult points you cannot understand;2) Try to complete exercise 1 and 2 on page 20;VII: Blackboard Design （板书设计）Para.1 changed a lotcalculating machineanalytical machineuniversal machine英语学习讲义PC(personal computer)laptopPara.2 memory improvedtubes--transistors--chips—network--WWWPara.3 applicationscommunicationfinance / tradescience and technology。

ALike any new ninthgrader on the first day of school, Joemar Class had ninthgrader emotion (情绪). He's not used to school in Hartford. He's used to going to school in his hometown of Florida, used to seeing his friends, used to having class in Spanish.“Nervioso，”he said in Spanish.We first met Joemar in midOctober in the San Juan Airport. His father, Guillermo Class, had sold his car to buy plane tickets to get his kids and fly them up from Puerto Rico. The island was almost destroyed (毁坏) by the deadly storm —Hurricane Maria.Now, they are settling into their new home in Hartford's South End. A week later, and, using his wife's car, Class drove 16yearold Joemar to his first day at Bulkeley High School. After a short ride, he got out in front of his new school. Inside, he met Gretchen Levitz — the school's program director.“I see you have a new uniform (校服)，” Levitz said. “You look great. Are you ready for a good first day？”Then he met a couple of teachers.“Hello，” they each said in Spanish. They asked where he's from, and told him they were happy to see him. Then, Levitz took him on a quick tour of the school before classes began — to her office, the school store, the library, and the dining hall.A total of 19 languages are spoken in Bulkeley High School. “We have so many new students coming here from other countries every single day，” Levitz said. “So it's not like he's the only one who has that feeling.”“You could tell he's a little worried，” Guillermo said as we left. “But, at the same time, he's looking forward to it.”【语篇解读】本文是新闻报道。

什么是机器人
美国是机器人的诞生地，早在1962年就研制出世界上第一台工业机器人，
比起号称"机器人王国"的日本起步至少要早五六年。
经过30多年的发展，美国现已成为世界上的机器人强国之一，基础雄厚，技术先进。
讲到什么是机器人时，我们大多数人都看到过电影或书本里描绘的外形酷似人类的机器人，这是机器人的一种表现形式。
可机器人并不一定非得是这样的。
事实上，机器人的形状各式各样。
我们身边到处都有机器人。
机器人能够代替人类完成重复乏味或者危险的工作，提高我们的生活品质和工作效率。
机器人技术综合机械工程、电子工程、传感器应用、信息技术、数学、物理等多学科知识，代表着一个国家的高科技发展水平。
实际意义上的机器人，应该是“能自动工作的机器〞有的功能很简单，有的就复杂得多。
例如：家里的供暖系统，我们只需做最初设定接下来它就能自己工作，我们身边的大多数家用电器都是这样。
自动温控系统的元器件遍布于整座智能化大楼。
