借鉴ESP理论,汉语科技语体所含词汇可分为四类,即汉语基本词语、书面通用词语、半科技词语和科技词语。编写预科留学生科技汉语教材,选词重点应该是书面通用词语和半科技词语。这样有利于提高教材的针对性,有利于突出科技汉语教材的特色。 Using ESP theory for reference, the vocabulary contained in the Chinese S & T genre can be divided into four categories: Chinese basic words, written general words, semi-scientific words and scientific words. The preparation of science and technology textbooks for international students should focus on writing general terms and semi-scientific terms. This is conducive to improving the pertinence of the textbook, which is good for highlighting the features of the textbook of science and technology Chinese.
