一、切分层次法其具本步骤是首先切分语段层次,概括层意;然后筛选有效信息,留主舍次;最后根据题目要求,准确压缩。例如:概括下面一段材料的主要内容。(不超过48字)(2004年高考天津卷第23题)钛合金强度大,重量轻,耐热性能好,适用于船只、汽车、航空航天工业,被人们视为未来材料
First, divide the hierarchy method The first step is to divide the level of the discourse and summarize the meaning of the hierarchy. Then, the effective information is filtered and the subject is retired. Finally, according to the requirements of the topic, the accuracy is reduced. For example: Summarize the main content of the following paragraph. (No more than 48 words) (2004 issue of Tianjin Vol.23) Titanium alloy has high strength, light weight, and good heat resistance. It is suitable for ships, automobiles, and aerospace industries. It is considered as a future material by people.
