Lesson 1 人教版必修2 Unit 3 (1) 课文讲解 WHO AM I? 【1】Over time I have been changed quite a lot. I began as a calculating machine in France in 1642. Although I was young I could simplify difficult sums. I developed very slowly and it took nearly two hundred years before I was built as an analytical machine by Charles Babbage. After I was programmed by an operator who used cards with holes, I could "think" logically and produce an answer quicker than any person. At that time it was considered a technological revolution and the start of my "artificial intelligence". In 1936 my real father, Alan Turing, wrote a book about how I could be made to work as a "universal machine" to solve any difficult mathematical problem. From then on, I grew rapidly both in size and in brainpower. By the 1940s I had grown as large as a room, and I wondered if I would grow any larger. However, this reality also worried my designers. As time went by, I was made smaller. First as a PC (personal computer) and then as a laptop, I have been used in offices and homes since the 1970s. 【2】These changes only became possible as my memory improved. First it was stored in tubes, then on transistors and later on very small chips. As a result I totally changed my shape. As I have grown older I have also grown smaller. Over time my memory has developed so much that, like an elephant, I never forget anything I have been told! And my memory became so large that even I couldn't believe it! But I was always so lonely standing there by myself, until in the early 1960s they gave me a family connected by a network. I was able to share my knowledge with others through the World Wide Web. 【3】Since the 1970s many new applications have been found for me. I have become very important in communication, finance and trade. I have also been put into robots and used to make mobile phones as well as help with medical operations. I have even been put into space rockets and sent to explore the Moon and Mars. Anyhow, my goal is to provide humans with a life of high

M o d u l e 1 Unit 1 School life School life in the UK Going to a British high school for one year was a very enjoyable and exciting experience for me. I was very happy with the school hours in Britain because school starts around 9 a.m. and ends about 3.30 p.m. This means I could get up an hour later than usual as schools in China begin before 8 a.m. On the first day, all of the new students attended an assembly in the school hall. I sat next to a girl whose name was Diana. We soon became best friends. During the assembly, the headmaster told us about the rules of the school. He also told us that the best way to earn respect was to devote ourselves to study and achieve high grades. This sounded like my school in China. I had many teachers in the past year. Mr. Heywood, my class teacher, was very helpful. My favourite teacher was Miss Burke---I loved the lessons that she gave in English Literature. In our class there were 28 students. This is about the average size for British schools. We had to move to different classrooms for different classes. We also had different students in some classes, so it was a struggle for me to remember all the faces and names. I found that the homework was not as heavy as what I used to get in my old school. However, it was a bit challenging for me at first, because all the homework was in English. I felt lucky, as all my teachers gave me much encouragement and I enjoyed all my subjects: English, History, English Literature, Computer Science, Maths, Science, PE, Art, Cooking and French. My English improved a lot,as I used English every day and spent an hour each day reading English books in the library. I usually went to the Computer Club during the lunch break, so I could send e-mails to my family and friends back home for free. I also had an extra French class on Tuesday evenings. Cooking was really fun as I learnt how to buy, prepare and cook food. At the end of term we held a class party and we all had to cook something. I was glad that all my classmates were fond of the cake that I made. Students at that school have to study Maths, English and Science, but can stop studying some subjects if they do not like them, for example, History and French. They can choose other subjects like Art and Computer Science or Languages such as Spanish and German. In the Art class that I took, I made a small sculpture. Though it did not look very beautiful when it was finished, I still liked it very much. I missed Chinese food a lot at lunch. British food is very different. British people like eating dessert at the end of their main meal. After lunch, we usually played on the school field. Sometimes I played football with the boys. Sometimes I just relaxed under a tree or sat on the grass. I was very lucky to experience this different way of life. I look back on my time in the UK with satisfaction, and I really hope to go back and study in Manchester again. 一、词汇过关填空: 1. Their grades are well above a_____. 2. C______ this book with that one, and you’ll find that one is better. 3. I was s ____at first, but soon I stopped worrying. 4. All the students are making p______ for the word test.

Or are you afraid that your friend would laugh at you, or would not understand what you are going through? Anne Frank wanted the first kind, so she made her diary her best friend. Anne lived in Amsterdam in the Netherlands during World War II. Her family was Jewish so she had to hide or they would be caught by the German Nazis.

新高一衔接班英语讲义

第一课时(公开课) 一、上衔接班的必要性 初中和高中的差异: 1教材跨度大.与初中简单的基础英语相比,高中英语容量大,要求高,节奏快,这就致使很多学生一时难以适应。其实从高中英语的设置和心理学上分析,我们不难找到答案.初中生升到高中,都有一种兴奋的心情。但在看到越来越多的新单词,越来越长的课文后;在听到越来越快的听力语速后;在碰到越来越复杂试题后,在老师的全英文授课的"熏陶"下,他们中的一些人不免会产生畏难的情绪,有的人就觉得自己不是学英语的料,干脆就不学了。其实这部分学生不是不想学,而是觉得高中的英语教材与课堂与初中太不一样了,就错误的认为自己没得救了,这就好比吃惯了中餐的人会觉得西餐很难吃,而导致不愿意吃一样。 2.初高中英语教法有所不同.初中时候,学生习惯于老师用汉语解释英文,不习惯高中 老师全英语教学,教师课堂常用语掌握太少;初中生习惯于老师对课文逐句翻译, 不习惯对课文篇章理解和深层理解;初中生习惯于老师教读生词,不习惯自己拼读,缺乏一定的音标知识;初中生习惯于听老师简单重复操练, 不重视思维能力的培养和语言的综合运用能力. 3.考试内容不一样山东省高考和济南市中考题型比较。 (2)对策: 1教材跨度大.未雨绸缪,衔接班为初高中英语搭桥。 2.初高中英语教法有所不同。打牢基础,以不变应万变;主动适应环境,而不是让 环境适应你。 3.考试内容不一样。知己知彼,百战不殆。 二、做好辅导计划 1.语音方面纠正语音 2. 单词方面 . 如何记单词:谐音法university math ambition pest amaze 词根词缀法press press ure com press de pressed depress ion ex press express ion im press impress ion impress ive op press spect in spect re spect ex pect sus pect
