对于雅思口语Part 1和Part 3中的优劣类问答题，有六个用来快速思考理由思考理由的关键词，可以供备考时间过短或者口语基础太“潮”的同学在考试时实在想不出思路被“干”在那儿时解围使用：
Time
Cost
Mood
Health
Safety
Knowledge
 
其中health除了身体健康physical health也包括心理健康psychological health比如我们来看一道Part1中较“另类”的考题：
Do you think children should be allowed to drive?

这个题的视角很蹊跷，但是没关系，不妨试试六字诀：
Time-Kids can get to school earlier if they are allowed to drive.
Cost-It would cost more for teenagers to learn to drive.
Mood-Driving is exciting for youngsters, no doubt about it.
Health-If children got hurt in an accident, they would suffer more physically and psychologically.
Safety-Some teens may will NOT be able to drive safely.
Knowledge-It would be nice if children could learn more about traffic rules through driving.
 
这只是一点提示，也可以完全用这六个提示词想出属于自己的ideas.
需要提醒的是：六字诀对口试的Part1和Part3问答题最有效，而对于Part2卡片题的思路来说，则还是沿着本书Day8中每类话题里的展开思路表格思考更有效。
 
但也有特例，比如最近在大陆考区有道十分著名的Part2卡片熊经常出没：
Describe a TV show that you dislike.(不喜欢)
喜欢的电视节目比较好说，但描述自己不喜欢的节目却不太容易深入下去。
 
也用六字诀试试：
Time-Too late (around midnight) and terribly long
Cost-It cost (cost的过去时还是cost) a huge amount of money to produce.
Mood-It’s totally heavy (沉重的) and depressing（非常压抑的）.
Health-Filled with violent scenes and is psychologically damaging to youngsters.
Safety-I’m even afraid it would lead to some youth crimes.
Knowledge-It doesn’t bring any fresh ideas and is often interrupted.(节目中间被打断) by stupid ads.(如果内容庸俗的则可以说It’s tacky.)
这样一个TV show 足以给人nightmare了吧。
 
在头脑中实用六字诀需要对它们大量练习，熟练掌握才能在考场中用于自如。如果觉得自己已经很有把握了，那么可以再加上View (美观还是丑陋) 这条补充理由作为备用，如果连前面六条还没记熟就不考虑这条视觉理由了。
 
最后还是要强调：六字诀知识在实在没有招儿了时作为救命稻草，对于能自己快速想出ideas的题就完全不必依赖它们，毕竟在雅思口语里流利度是相当重要的一个指标。
