所谓“定义法”，就是下定义，对题目中的某些名词或概念进行解释，比如题目所涉及的success, responsibility, independence,social skills，part-time jobs等，我们可以直接解释这些概念是什么，或者大家对这些事物的看法等，还有可能涉及到重要性或者其影响等词，比如importance, benefits, advantageous,exert positive/negative influence on，一般一句话带过即可。下面我们结合具体题目带入“定义法引入”的具体应用。
D/A: One ofthe best ways that parents can help their teenager children prepare for adult life is to encourage them to take a part-time job.
在这个题目中，所涉及到的名词有parents, teenager children, adult life, 和a part-time job四个名词及词组，也就是说这个题目我们可以从四个角度进行开头段的构思。但我们应该优先从最好把握的入手。不难发现，a part-time job属于话题的关键词眼，所以`第一步`我们可以直接针对a part-timejob进行解释，比如Part-time jobs, which act as a warm-up for the future career, can provide children with a general image of the society. 或者Part-time jobs is of great importance in helping children better understand the society they are live in.定义法解释过之后，`第二步`我们要引出题目中的其它对象，最后第三步引出自己立场。比如上边紧接着a part-time job 这一句可以For most parents, it is really an ideal choice to help their children prepare for adult life.`第三步`在点明观点时，我们可以紧接着提出，Thus I agree with the opinion in the statement.甚至最后可以加一句，比如：my reasons will be detailed as follows. 或者my reasons are as follows.
Part-time jobs, which act as a warm-up for the future career, can provide children with ageneral image of the society.For most parents, it is really an ideal choice to help their children prepare for adult life.Thus I agree with the opinion in the statement. My reasons will be detailed as follows.
Parents, as the most essential guide in our life, love us so much that they always want a fast and steady development of us. Thus, many parents suggest their children to work on a part-time job, which acts as a warm-up for their future career. From where I stand, I agree with the suggestion to take on a part-time job during teenage period. My reasons are listed as follows.
Teenage is the most crucial period in one’s life, for it is a fast developing stage both in physical and mental aspects. That is why parents are urged to figure out the most efficient way for their children to keep up with the quick development. Working on a part-time job is considered one of the best solutions for many parents. From where I stand, I agree with the suggestion to take on apart-time job during teenage period. My reasons are listed as follows.
Many teenagers are looking forward to the adult life while the other are reluctant to grow up. However, growing up is an inevitable process/stage in one’s life. Part-time job, which acts as a warm-up for the future career, gives children a general image of the society.From where I stand, I agree with the suggestion to take on a part-time job during teenage period. My reasons are listed as follows.
我们还可以以同样的方法带入其它题目，比如D/A: People should have hobbies and do physical activities that are very different from work.
这个题目所涉及名词有work和hobbies and physical activities，我们就以work为切入点，进行定义，然后引出开头段。比如：
For most people, work takes a massive part of our whole lives. We to school to prepare for a career, work through our best years, and eventually, after retirement, live off of pension generated from the job. However, other than the monetary part, our hobbies and physical activities might benefit us more if they were different from our jobs.
