Review the paragraphs in Reading. 2. Learn the grammar and usage: the development of a text. Teaching Procedures: Step 1 Greetings Greet the whole class as usual. Step 2 Lead in Let’s review the text of reading and answer the questions · How many paragraphs are there in the text? · There are ten paragraphs. · What is the title of the text? · The title is Aids today. · Can we learn what the text is about from the title? · Yes.

A text should be written in the way that allows readers to move from one idea to the next easily. For a text to develop logically, we should include the following: · The title · The beginning paragraph · The body paragraphs · The concluding paragraph. · What should a title be like? · It should not be too long and should be clear and simple, for example ‘Aids today’ ‘The search of happiness’ ‘The UN-bringing everyone closer together.’ · How do you understand these titles? · ‘Aids today’ is about the deadly disease of Aids at the present time. · ‘The search of happiness’ is about how to find happiness · ‘The UN-bringing everyone together’ is about the functions of UN. · What should be included in the beginning paragraph? · It should contain a topic statement. · It should have supporting sentences. · It should capture reader’s attention and keep them interested in reading the text. · Each body paragraph usually contains a topic sentence, some supporting sentences and a concluding sentence to the paragraph. · What should the topic sentence be like? · The topic sentence contains the main idea of the paragraph and should be simple and clear for readers to catch its meaning. · Where can it be found? · It is usually the first sentence of the paragraph. · What are supporting sentences? · Supporting sentences follow the topic sentence and provide details or proof to support it. They expand on the idea presented in the topic sentence. · What is the function of a concluding sentence in a paragraph? · The last sentence of a paragraph sometimes introduces the main idea of the next paragraph. · How does the concluding paragraph function in a text? · It should contain a final topic statement (or maybe a prediction), or it could refer to the example mentioned in the beginning paragraph. 【设计说明】通过具体的讲解让学生明白如何写好一篇英语作文。 Step 4 Consolidation Read the sentences and then decide which paragraph they belong to and what type of sentence each one is. 【设计说明】通过几个典型例子的呈现来巩固所学内容。 Step 5 Homework 根据下列提示，以How to Stay Healthy（如何保持健康）为题写一篇150词左右的短文。 1. 健康很重要； 2. 如何保持健康？（可从适当的营养、充足的睡眠、经常的锻炼方向考虑。) 第一段写虽然人们越来越重视健康，认为健康是最重要的财富，但对如何保持 健康却不一定清楚，引出“我”的建议。第二段写“我”有三条建议，一是吃富含蛋白质的食品、蔬菜和水果，不要吃得过甜、过油腻以及过量；二是保证充足睡眠，至少每天睡8小时，如有可能，也应午休；三是适度锻炼，因为“生命在于运动”。第三段总结全文。 How to Stay Healthy People are beginning to attach much more importance to their health these days than ever before. They begin to realize that good health is the most valuable possession a person can have. However, many people don’t know how to stay healthy although great efforts have been made in this regard. In my opinion, there are three things we can do if we want to be in good health.     First, we should have the right food, because proper nutrition is the most important for good health. Avoid foods with lots of sugar and fat. Eat plenty of high protein foods, vegetables and fruits. Do not overeat. Secondly, we should get proper amount of sleep, because without enough sleep, we will often feel tired and irritable. Allow ourselves at least eight hours of sleep each day. Have a nap at noon if time permits. Finally, we should exercise regularly, because ‘life depends on exercise’. Regular exercise strengthens our hearts and lungs. In addition, it prevents us from putting on weight.     If everyone is to do so, there will be much less complaining about poor health and there will be much more happiness in our life.
