在批改学生写的雅思英语作文时，经常遇到下面这样的句子：
　　The test does not require the skills that are used in everyday driving situations. 驾照考试并不考查日常驾驶情形下常用的驾驶技巧。He's very concerned about his students. 他很关心他的学生。这样的句子似乎没什么问题，语法也正确，词汇也还ok，内容也没有偏题。
　　但英语作文中，好的句子，不应只是满足上面的基本要求，还应做到“内容的具体（Specefic）”
　　何为内容的具体所谓内容的具体，是指读者能够从句子中看到画面感，能够有具体的细节，而不是抽闲空洞的内容。
　　例如：在上述第1句话中，什么样的技能才是日常常用的驾驶技能呢？在第2句话，他很关心学生，可是他是如何关心学生的呢？所有这些细节，我们都无法从句中看出。
　　因此，在雅思大作文写作过程中，我们应该尽量避免这样的句子。尽量做到，让句子充满细节内容，让内容呈现画面感。
　　针对上面2句话，我们可以作如下修正：The test does not require the skills that are used in everyday driving situations.To be eligible drivers, they should also master the traffic rules, and know how to turn left/right, to drive backward, to use the car brake, and to accelerate /decelerate, etc.
　　eligible drivers: 合格的司机master the traffic rules 掌握交通规则turn left/right 左/右转弯drive backward 后退倒车use the car brake 刹车accellerate/ decelerate 减速或减速 He's very concerned about his students.He groups students together at least once a week to solve their study problems, and to learn about their physical health and psychological state.
　　solve their study problems解决学习问题physical health 身体健康psychnological state心理状况
