牛津高中英语教学设计单 元：Unit 3 The world online板 块：Task 2Thoughts on the design:本节课是以说、写技能为主的语言输出课，说的部分旨在帮助和指导学生如何提问专业性的问题，所以在该部分的设计上主要创设语境，鼓励和指导学生如何对图表和曲线图提出详细问题并讲解图表所示的事实和数据, 以及帮助学生梳理课本第二部分的内容和获取相关信息回答上述问题。学生学会通过网上调查“人们观看和收听新闻”的不同途径并写出此报告。通过这些活动，提高与上述内容相关话题的口头表达能力和写作能力。Teaching aims:After learning this period, the students will be able to1ask technical questions for more detailed information;2write a report on how people get news from the Internet;3to apply these skills practically by doing research on the Internet and to finish a report about a speech on differently ways people watch or listen to the news.Teaching procedures: Step 1 Skills building 2: forming more specific questions (PPT 4-7)Read the guidelines1. Start with information that you know and build on it. If you know or have just learned that 60% of people prefer football to table tennis, you can then ask: (1) Does a persons age affect their answer? (2) Do men and women answer in the same way?(3) Is football becoming more popular, or is table tennis becoming less popular?2. Do not just ask about what people like, prefer or choose to do. Also ask what they do not like or do not prefer. For example: (1) Other than table tennis, what sport do people not like to play?(2) What sport do people prefer table tennis to?3. Find out why. Once you have the facts, you can try to find out why they are true. This kind of information will be helpful if you need to support or explain the fact you have learned, e.g.Why is football more popular?Explanation帮助学生设计科学提出问题的方式及内容，训练口语表达能力。Step 2 asking more specific questions (PPT 8-15)Student 1: Form questions using the information on the left.

The most popular way to get news is to read newspaper, but some people have switched to the Internet. Do you know why? What do you think are the problems with newspapers?(I think it is mainly because newspapers are too big and most of them are messily printed. News on the Internet is updated each hour while news in newspapers can not be updated.)7. Why do you think some people prefer television?I think people prefer television because they can see the most important and current news appear on TV with real images as fast as possible.8. Why do you think some people still prefer radio?(These people can listen to news while driving or doing housework at the same time. No time is wasted.)

C凝血酶时间延长 bar chartC纤维蛋白原定量检查凝血物质消耗情况The bar chart shows the weight in kilograms of some fruit sold one day by a local market. We can see that 52 kg of apples were sold, 40 kg of oranges were sold, and 8 kg of star fruit were sold.3. flow/line chartThe chart shows how John's weight varied from the beginning of 1991 to the beginning of 1995. The weight scale runs vertically, while the time scale is on the horizontal axis. Following the gridlines up from the beginning of the years, we see that John's weight was 68 kg in 1991, 70 kg in 1992, 74 kg in 1993, 74 kg in 1994, and 73 kg in 1995. 4.5. 借：固定资产 1500pie chart9肝功能严重障碍诱发DIC与下列哪一过程无关？The pie chart shows the fractions of dogs in a dog competition in seven different groups of dog breeds. We can see from the chart that 4 times as many dogs competed in the sporting group as in the herding group. We can also see that the two most popular groups of dogs accounted for almost half of the dogs in the competition. Suppose 1000 dogs entered the competition in all. We could figure the number of dogs in any group by multiplying the fraction of dogs in any group by 1000. In the toy group, for example, there were 0.12 × 1000 = 120 dogs in the competition.借：营业外支出 7200Explanation题解 在DIC晚期，因凝血物质消耗性减少和继发性纤溶系统激活，使纤溶系统活性大于凝血系统活性，表现为出血。这里虽然提供了三个图表，可以让学生选择当中的一个。要求学生用英语表达所读的图，从简单的一个句子的训练到完整的一段话的训练，能更好地提高学生的口语能力。Step 5 e-mailing a report (PPT 26-30)Dear sir,I went to listen to two speeches about the ways people get news. From the first speaker, I know there are different types of news, such as sports results, weather, politics and current affairs, and some of them are more suited to sources like radio, newspapers, and television. There is no doubt that the Internet is increasingly popular, but the number of people who get their news from the Internet is still small. I have collected some figures from two charts, each of which is a survey of 500 people. According to the two charts, the percentage of people who turn first on the Internet for news on emergency, opinions, weather, breaking news and sports results is respectively only 2 per cent, 5 per cent. However, for news on emergency and breaking news, the percentage of people who turn first to local TV comes to 53 per cent and 48 per cent. Why will people not turn first on the Internet to get news? The second speaker gave the following reasons: first, the Internet is still not accessible to everyone; second, information on it is often uncontrolled; third, people do not always trust the news online.Yours,(Students own name)Step 6 Homework（PPT 31）借：其他业务收入 851.
