注 1：注意现在分词作前置定语的特点是：被修饰的⼈或物能产⽣前⾯ -ing 的动作。例如：
- the hard-working people 勤劳的⼈⺠，
- fast moving molecules 快速运动的分⼦等。
- building materials 建筑（⽤的）材料，
- cooling water 冷却⽤⽔，
- the boiling temperature (或point) of water ⽔的沸点。表⽰该温度与“沸腾”或“煮开”动作有关⽽已。
- 若写 the boiling water，则为（这）正在沸腾的⽔；
- 若写 the boiled water，就变为“（煮）开过的⽔”。

- 1. 限定词，如冠词，this，those 等指⽰代词、物主代词等。但要注意冠词有时不占⾸位的⼏种情况（参阅第 1 节、定语（包括定语从句）和⼏个注意点I. 前置定语。
- 2. 基数词、序数词；

必须指出，修饰名词的前置定语⼀般不会太多(通常不超过三、四个)如果有⼏个前置定语，⼤致可按上述顺序排列，允许循序跳着使⽤。与汉语⽐较，则和上述第 8 位的英语形容词的⽤法差别较⼤，应予以注意。
