一、应用写作思维训练描述模型(models)是什么在我们日常生活和工作中,经常遇到模型或用到模型,比如,儿童玩具、建筑模型、飞机模型等都是实物模型,另外还有文字、符号、图表等描述现实客观事物的某些特征和内在联系的模型,如地图就属于这一类。科学家或工程师在研究实际的或拟议的系统的时候,为了便于实验和预测,总是先要设法把所要研究的系统的结构形态或运动状态变为易于考察的形式即模型。模型是系统过程的一种简化、抽象和类比表示,它不再包括原系统或过程的全部特征。模型是 First, the application of writing training to describe what the model (models) is What in our daily lives and work, often encountered models or models used, such as children’s toys, building models, aircraft models are all physical models, in addition to text , Symbols, diagrams and other models that describe some of the characteristics and intrinsic relations of the objective things in the real world. For example, maps belong to this category. When scientists or engineers study actual or proposed systems, in order to facilitate experimentation and prediction, it is always better to try to change the structural or movement state of the system to be studied into a model that is easy to examine. A model is a simplified, abstract, and analogous representation of a system process that no longer includes all the features of the original system or process. The model is
