变脸是川剧表演艺术的特殊技巧之一，他是剧中人物内心思想感情的一种浪漫主义的表现手法。反应出主人公的情绪变化。每次看到变脸，除了对艺术的无比崇尚和敬畏外，更体现出演员技巧的高超和娴熟。
此时，它让我想到了雅思阅读！阅读中何尝不也是运用变脸的技巧呢！阅读的题型变脸幅度最小的莫过于T/F/NG，就像川剧变脸中的抹脸，用手往脸上一抹，就完成了变脸的过程。判断题也是如此，比如词性的改写：
文章：it is clear from the statement that the creation of health is more significant than encouraging healthy individual behaviors and lifestyles and providing appropriate medical care.
题目：the socio-ecological view of health recognizes that lifestyle habits and the provision of adequate health care are critical factors governing health.
从题目和文章中可以发现，出题者一直在做变脸的工作。他把文章中的providing 变成了provision,把medical care 小变成了health care.
所以，如果同学们从词性变化的角度来看待题目，很多题目可以迎刃而解。
变脸的另外一种叫做吹脸，就是在地上放上化妆品，然后演员利用舞蹈，在倒地的一瞬间，吹一口化妆盒里的粉末，完成变脸。这个技巧难度大，变的彻底一些。我把它比作matching题型，因为这个题型变脸的幅度要大一些。
文章：if the function of play was to get into shape, the optimum time for playing would depend on when it was most advantageous for the young of a particular species to do so.
题目：play is not a form of fitness training for the future.
这道题目中的变脸方式比较的不讲人情味。出题者看来是不了解中国的国情。不知道，中国学生从小到大背fit这个单词的时候，都是适合的意思，因此，大多数学生会据此推断fitness是适应的名词。哪里晓得居然是健身的意思。从get into shape 到fitness算是一次变脸的尝试。
川剧变脸中最有魅力的当属于扯脸。据传巨星刘德华也沉迷其中。扯脸变化大，比较复杂。一般用丝线系在身体的隐秘处，轻轻的一扯，完成变脸。和它对应的只有是无极的段落配对题了。
文章：inside the academies, science takes centre stage. The AIS employs more than 100 sports scientists and doctors, and collaborates with scores of others in universities and research centers. AIS scientists work across a number of sports, applying skills learned in one- such as building muscle strength in golfers- to others, such as swimming and squash. They are backed up by technicians who design instruments to collect data from athletes. They all focus on one aim: winning. ‘We can’t waste our time looking at ethereal scientific questions that don’t help the coach work with an athlete and improve performance,’ says Peter Fricker, chief of science at AIS.
题目：a reason for narrowing the scope of research activity.
文章和题目简直就是大变脸！题目中的reason文章中只字未提但却把变脸的那根丝线隐藏的很深。就是那句 they all focus on one aim: winning. 一切尽在不言中。出题者把中国国粹演绎的如此精确，实乃妙哉！
