应用题就结构来说,可以分成条件和问题部分。条件是解题的依据,问题则决定着解题的思考方向。要正确地解答应用题,首先要正确地理解题意。这就需要认真审题: 1.理解关键性词语。由于应用题数量关系寓于文字叙述之中,因此,对题中的关键性词语必须正确理解。 第一,对一些数学术语,如:单价、数量、总价;速度、时间、路程;工作效率、工作时间、工作总量;相遇、迫及等概念,应当从它们的相互关系中理解各自的含义。
The application questions are structurally divided into terms and problems. Conditions are the basis for solving problems, the problem determines the direction of thinking problems. To correctly answer the application questions, we must first correctly understand the questions. This requires careful examination: 1. Understand the key words. Due to the relationship between the number of application questions in the text narrative, therefore, the key words in the question must be correctly understood. First, concepts such as unit price, quantity, total price, speed, time, distance, work efficiency, working time, total amount of work, encounters, forcing and so on should be understood from their interrelationship meaning.
