在某种程度上，人们的生活离不开电脑。
首先，与传统的方法相比，电脑可以帮助人们更快地解决更难的科学问题；其次，人们可以通过网络互相分享信息；此外，对我们学生而言，我们不仅可以从网络上下载有用信息还可以通过充分利用网络来提高学习成绩。
例如，在电脑的帮助下，我们既可以扩大词汇量又可以提高我们的听说读写能力。
然而，任何事物都有两面性。
网络充满着冒险。
如果病毒袭击了我们的电脑，我们的个人信息就有可能暴露；更糟糕的是有些同学沉迷于网络游戏或网络聊天，这严重影响了他们的学习。

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.

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。
