开头段
首先，开头方式可以采取四种：直接陈述观点+概述理由;比较双方观点，阐明自己观点;背景开头+立场;提问+立场。下面我们逐一来看一下四种方式的具体例子。
第一种：直接陈述观点+概述理由
I agree with the speaker's broad assertion that money spent on research is generally well invested. However, the speaker unnecessarily extends this broad assertion to embrace research whose results are "controversial," while ignoring certain compelling reasons why some types of research might be unjustifiable. My points of contention with the speaker involve the fundamental objectives and nature of research, as discussed below.
例文中先支持原文观点：把钱话在研究上是很好的投资;然后转折：结果有争议的研究可以不包含在投资范围的;最后，引出下文要论述的理由。
第二种：比较双方观点，阐明自己观点
There is much debate over the universal issues whether or not tradition and modernization are incompatible. Some people may claim that they necessarily conflict with each other, while others argue that the two are not mutually exclusive. Insofar as I can think, the best way is to coordinate them and exert their own advantages for contemporary society.
第一句改写题目，第二句比较两种立场，第三句提出自己的观点。这种开头比较简单易学，也是同学们比较常用的开头方式，需要注意的是在点明自己的观点的时候，最好把下文中要进行分层论证的关键词结合到句子里面，比如上述例子中的coordinate ;exert their own advantages，可以起到引领下文，令文章结构严谨的作用。
第三种：背景开头+立场
Explosive development of science and technology has been made during the past one hundred years or so. When it comes to progress of the condition of humanity all over the world, there are always a host of different opinions held by different individuals from different areas. Have, you may wonder, the technology developments or innovations contributed to promoting our humanity? Admittedly, most people would consider that there are still so many troubles with us such as poverty, violence, conflicts and even wars. However, as a whole effect in general, technology progress has in fact, tend to lead to a significant promotion of the overall condition of humanity in the world.
第一步，先做背景引入，第二步提出自己的立场。这种开头方式的优点呢，是可以体现写作者的知识储备和语言水平，但是缺点是不如上述的两种方法简单易学，在做与题目相关的背景展开的时候容易落入俗套。所以，同学们在练习的时候需要选择适合自己的方法。
第四种：提问+立场
What are the limits of our duty to save endangered species from extinction? The statement raises a variety of issues about morality, conscience, self-preservation, and economics. On balance, however, I fundamentally agree with the notion that humans need not make "extraordinary" efforts--at the expense of money and jobs--to ensure the preservation of any endangered species.
以问句的形式开头，然后表明自己立场的开头段可以体现出句式的变化，与传统的开头方式相比，比较有新意，想要尝试变化的同学可以多练习一下。
结尾段
接下来我们来看结尾段。Issue的结尾最大的作用就是起到结构完整的作用，加上答题时间有限，因此，结尾段不需要再花费额外的精力来提出新观点了，只需要对文章做一个结构上的总结就可以了。下面的2个结尾段的句式，同学们可以根据自己的喜好，将句子改写成自己的写作模板，切记对任何句子和范文不要原模原样照搬，防止发生雷同，造成成绩无效的严重后果。
第一种：总结结论+总结理由的方法
To sum up, given the reasons mentioned above, we may safely come to the conclusion that…. not only because…, but also because…, but it depends on
第二种：回顾题目立场+再次确认自己立场
In sum, I concede that….Nonetheless, to some extent…, the speaker's claim overrates/underrates the importance of sth…. In the final analysis, the optimal approach, in my view, is a balanced one that ….

经典写作范例展示
作文话题：The best way to teach is to praise positive actions and ignore negative ones.
The recommendation presents a view that I would agree is successful most of the time, but one that I cannot fully support due to the “all or nothing” impression it gives.
Certainly as an educator I agree fully that the best way to elicit positive response from students is to make use of students’ positive energy and then encourage actions that you would like to see repeated. It is human nature that we all want to be accepted and achieve on some level, and when people in authority provide feedback that we have done something well, the drive to repeat the action that was praised is bound to be particularly strong.
This blanket statement would obviously pay dividends in situations in which a teacher desires to have students repeat particular behaviors. For example, if an educator is attempting to teach students proper classroom etiquette, it would be appropriate to openly praise a student who raises his or her hand when wishing to speak or address the class. In such cases, the teacher may also help shape positive behaviors by ignoring a student who is trying to interject without approval from the teacher. In fact, the decision to ignore students who are exhibiting inappropriate behaviors of this type could work very well in this situation, as the stakes are not very high and the intended outcome can likely be achieved by such a method. However, it is important to note here that this tactic would only be effective in such a “low-stakes” situation, as when a student speaks without raising her hand first. As we will discuss below, ignoring a student who hits another student, or engages in more serious misbehaviors, would not be effective or prudent.
To expand on this point, it is important for teachers to be careful when working with the second half of this statement, only ignoring negative actions that are not serious. Take for instance a student who is misbehaving just by chatting with a fellow classmate. This student might not be presenting much of a problem and may be simply seeking attention. Ignoring the student might, in fact, be the best solution. Now assume the negative action is the improper administering of chemicals in a science experiment or the bullying of a fellow student. To ignore these negative actions would be absurd and negligent. Now you are allowing a problem to persist, one that could potentially lead to much bigger and more dangerous issues. In a more serious situation, addressing the negative actions quickly and properly could stop the problem it in its tracks. It is for reasons like this that I do not advocate the idea that a teacher can be successful by simply ignoring negative actions.
I do, however, greatly support the idea that the central focus of teaching should be to build on and encourage positive actions. However, the author’s all-encompasing statement leaves too many negative possibilities for the classroom. Perhaps a better way to phrase this statement would be to say, “The best way to teach is to praise positive actions and ignore negative ones that are not debilitating to class efficiency or the safety of any individual”.
Thus, in the original statement, there are indeed some good intentions, and there could be a lot of merit in adopting its basic principles. Data proves that positive support can substantially increase motivation and desire in students and contribute to positive achievements. In fact, most studies of teaching efficacy indicate that praising positive actions and ignoring negative ones can create a more stable and efficient classroom. It needs to be stressed, however, that this tool is only effective at certain levels of misbehavior. As mentioned above, when the behavior is precipitated by feelings of revenge, power or total self-worthlessness, this methodology will likely not work. It is likely to be very successful, however, when the drive behind the misbehavior is simple attention seeking. In many of these instances, if the teacher demonstrates clearly that inappropriate behavior does not result in the gaining of attention, students are more likely to seek attention by behaving properly. Should the student choose this path, then the ignoring has worked and when the positive behavior is exhibited, then the teacher can utilize the first part of the theory and support or praise this behavior. Now it is much more likely to be repeated. If the student does not choose this path and instead elects to raise the actions to a higher level that presents a more serious issue, then ignorance alone cannot work and other methods must be employed.
In conclusion, one can appreciate the credo expressed in this instance, but surely we all can see the potential error of following it through to the extreme.
