江苏省西亭高级中学 自主学习导引课题：Module 7 Unit 1 Welcome to the unitTeaching aims: get to know the technological developments and the background information a.一；课前预习；1） Read the following material:Picture 1Early TV had antennae on top. The screen was very small and could show only black-and-white pictures. The size of the TV was small compared with modern TV, and usually it looked like a wooden box. Early TV also did not have a remote control. The control panel was on one side of the screen. And today we havePicture2People put the tapes into the recorder, then played the tape with music at one side and pushed the play and record buttons at the other side to record the music onto the blank tape. And today we have Picture 3The words in a paper dictionary are arranged in alphabetical order from A to Z. We need to look at the first letter of the word and use it to search in the dictionary. If two words start with the same letter, we look at the second letter to decide the alphabetical order. If the first and second letters are the same, we look at the third letter and so on.Picture 4People sent letters in the past, but letters were slow, and they took from a few days to several months to arrive. Then people invented the telegraph, but the telegraph could send only short sentences. Later, people could communicate via telephone, but the disadvantage was that not everyone had a telephone. Now, people use e-mails to communicate. E-mails are quick, but people without computers and access to the Internet cannot send e-mails. Today, most people use mobile phones to keep in touch with others. The size of a mobile phone is small so people can carry one in a pocket and receive and make calls wherever they are and whenever it is.Now, mobile phones have more and more functions. They can send text messages. They can also be used as a digital camera to take still or even moving pictures. People can send the pictures they take to other mobile phones or e-mail addresses. Mobile phones can be connected to the Internet and people can look at web pages with mobile phones. More technologically advanced mobile phones can receive TV signals so that people can watch live TV programmes on their mobile phones.预习交流 一）英汉互译1 ）看起来像_ 2）与-保持联系_3）列表_ 4 ) over time _5) 在过去的几十年 _ 二）根据课文填空；1）Early TV was in black and white and had_ pictures.2）Now we can record music _computer3）Dictionaries never looked_ this before.4）With mobile phones, we can keep in touch with other _ we are巩固练习1） 我有两只花猫，看起来像小老虎_2） 我们常通过手机联系_3） 技术的发展在过去几十年内取得了非凡的成就。_4） 你应该在常出错的地方做个标记_课后练习1)There is a new problem involved in the popularity of private care_road.

Before that time, large computers were only used by large, rich companies that could afford the investment. With the advancement of technology, small computers have come onto the market, which are capable of doing the work that used to be done by much larger and expensive computers, so now most smaller companies can use themThe main development in small computers has been in the field of word processors（处理器）, or WPS as they are often called. 40% of British offices are now estimated to have a word processor and this percentage is growing fast.There are many advantages in using a word processor for both secretary and manager. The secretary is freed from a lot of daily work, such as re-typing letters and storing papers. He or she can use this time to do other more interesting work for the boss. From a managers point of view, secretarial time is being made better use of and money can be saved by doing daily jobs automatically outside office hours.But is it all good? If a lot of daily secretarial work can be done automatically, surely this will mean that fewer secretaries will be needed. Another worry is the increasing medical problems related to work with visual display units（显示器）. The case of a slow loss of sight among people using word processors seems to have risen greatly. It is also feared that if a woman works at a VDU for long hours, the unborn child in her body might be killed. Safety screens to put over a VDU have been invented but few companies in England bother to buy them.Whatever the arguments for and against word processor, they are a key feature（特征）of this revolution in office practice.41.
