关于雅思写作目标7 的提分建议：首先，要达到6分作文的要求：观点不跑题，好的结构，写满250字。高分作文需要深度：使用丰富的词汇充分地解释自己的观点。在这一分数段，仅有好的结构是不够的，背连接短语也没用。你应该关注的是真正的内容。
　　什么是真正的内容：real content，比语法、连接或结构都更重要，是7-与7 的关键区别。真正的内容意味着所有的ideas都与问题的话题相关，而且使用了丰富的词汇（a range of good vocabulary）来表达这些ideas。
　　以“罪犯是否是向teenager讲授犯罪危险很佳人选”话题为例，范文中标出了能够体现真正的内容的词汇（短语）：
　　Some people who have been in prison become good citizens later, and it is often argued that these are the best people to talk to teenagers about the dangers of committing a crime.
　　To what extent do you agree or disagree?
　　It is true that ex-prisoners can become normal, productive members of society. I completely agree with the idea that allowing such people to speak to teenagers about their experiences is the best way to discourage them from breaking the law.
　　In my opinion, teenagers are more likely to accept advice from someone who can speak from experience.Reformed offenders can tell young people about how they became involved in crime, the dangers of a criminal lifestyle, and what life in prison is really like. They can also dispel any ideas that teenagers may have about criminals leading glamorous lives. While adolescents are often indifferent to the guidance given by older people, I imagine that most of them would be extremely keen to hear the stories of an ex-offender. The vivid and perhaps shocking nature of these stories is likely to have a powerful impact.
　　The alternatives to using reformed criminals to educate teenagers about crime would be much less effective. One option would be for police officers to visit schools and talk to young people. This could be useful in terms of informing teens about what happens to lawbreakers when they are caught, but young people are often reluctant to take advice from figures of authority. A second option would be for school teachers to speak to their students about crime, but I doubt that students would see teachers as credible sources of information about this topic. Finally, educational films might be informative, but there would be no opportunity for young people to interact and ask questions.
　　In conclusion, I fully support the view that people who have turned their lives around after serving a prison sentence could help to deter teenagers from committing crimes.
