接下来我们通过实例来了解中心句, 主题句与总结段的布置。比如:
Topic1: Is it not necessary to learn the skill of cooking due to the success of convenience food and read-made meals?
Thesis statement: But in my opinion, cooking is a very important ability we should not lose.
Topic sentence 1: First of all, the fact is that ready-made meals are not usually that good for us.
Topic sentence 2: Moreover, it is extremely important for children to learn how to cook, so that they will be fully independent when they grow up.
Topic sentence 3: Speaking personally, I have always enjoyed experimenting in the kitchen, by cooking slightly unconventional meals.
Conclusion: In conclusion, although some use of convenience food is natural, no one should rely on it exclusively at the expense of home-cooked food. Not only is this unhealthy but it is also threatening important skills with extinction.
Topic 2: Who should be responsible for our old people?
Thesis statement: In my essay I would like to note four different models.
Topic sentence 1: Firstly, the company can be responsible for their retired employees.
Topic sentence 2: A second solution is that the government has to have the responsibility for the old people’s care.
Topic sentence 3: Another way of solving this problem is to give back the responsibility to the individual.
Topic sentence 4: A last solution is to go back to the old model of the big family who cares for all their members.
Conclusion: To sum up I have to admit that I can’t find a really good solution for this problem. All models have advantages and disadvantages. Certainly we will have to go on thinking.
Topic3: Should students in high school study music as a compulsory school subject?
Thesis statement: While some think the study of music in high school is a waste of valuable school time, musical training and study is an important part of educational development.
Topic sentence 1: It is true that when it comes to the study and application of music, not everyone is suited.
Topic sentence 2: On the other hand, it is quite well-known that music can play an important part in the development of the human brain.
Conclusion: While not every student may be musically inclined, the study of music is a valuable inclusion in any student’s course of study. In addition to being excellent for mental growth and development, students of music learn discipline, persistence and patience. Music should be a compulsory part of a high school student’s education.
议论文的段落结构
与议论文的整体结构布置相类似，在段落的写作中我们也用“三明治”结构来进行写作，即把段落分为主题句(Topic Sentence)，支持部分(Supporting Sentences)和结尾句部分(Concluding Sentences)。（注意：并不是每个段落都一定要有结尾句，重要地是要让这个段落自然地结束，不能给读者留下话还没有说完的感觉。）段落结构如下图如示：
PARAGRAPH
|
Topic Sentence |
|
Supporting Sentences |
|
Concluding Sentence |
接下来我们通过实例来了解主题句，支持句与总结句的布置。比如：
1. Topic Sentence: First of all, the fact is that ready-made meals are not usually that good for us.
Supporting Sentences: They contain high levels of salt and sugar, not to mention harmful preservatives and artificial colorants.
Concluding Sentence: Therefore, a diet that is exclusively made up of such food is bound to be unhealthy.
2. Topic sentence: Teenagers find many ways to drive their parents crazy.
Supporting Sentence 1: First, they may dye their hair purple or they may shave their heads bald. They may also shred their new and expensive jeans and sit hours after hours in front of computers playing games or chatting with someone they never see.
Supporting Sentence 2: In addition, they spend hours windowing-shopping and on the phone. They have time to watch TV, but they do not have time to do their homework.
Supporting Sentence 3: Also, they are always too busy to clean their rooms, but they are never too busy to hang around in the streets.
Concluding Sentence: It is hard to be a teenager, but it is even harder to be parent of one.
3. Topic Sentence: In the second place, corporal punishment is by no means a desirable way of education a child.
Supporting Sentence 1: Numerous studies have shown that it does far more harm than good to children in their mental as well as physical development.
Supporting Sentence 2: For example, corporal punishment can give a child a sense of being treated unfairly, making him rebellious.
Concluding Sentence: This will be detrimental to the molding of the child’s character, and therefore should be avoided.
通过以上例子，我们可以清楚地把握雅思议论文结构（三明治结构），并可以通过练习一些雅思作文题目加以模仿，使得所写的文章结构良好，内容清晰、易读。良好的结构，清晰易读的内容也是好作文的一些特点。另外，专家建议考生在详细地学会如何发展段落以及组织整篇文章之后，可以把更多的时间放在对一系列常考写作话题“脑力震荡”上，即尽量地准备更多话题的相关地ideas来组织论据。
