斯大林在“马克思主义与语言学问题”里科学地指明词汇是构成语言的“建筑材料”;他又说:“词汇反映着语言发展的状态,词汇越丰富,越纷繁,那末语言也就越丰富,越发展。”他的话使我们充分认识丰富学生的词汇对发展学生的语言的重要意义。学生对学过的词汇是否都能透彻地理解和正确地运用,以及他掌握的词汇是否够丰富,这和他说话、写作与阅读的能力的发展是密切相关的。建筑家没有砖瓦等建筑材料,就盖不成房子,没有好材料也就盖不成好房子;学生没有掌握相当充分的词汇,也就是说,没有掌握相当 Stalin in the “Marxism and linguistics problems” scientifically pointed out that the vocabulary is the “building material” that constitutes the language; he also said: “The vocabulary reflects the state of language development. The more vocabulary the word is, the more complicated it becomes.” The language is richer and more developed." His words made us fully understand the importance of enriching students’ vocabulary in developing students’ language. Whether the student can thoroughly understand and use the vocabulary he has learned and whether he has enough vocabulary is closely related to the development of his ability to speak and write and read. If the builder does not have building materials such as bricks and tiles, he will not build a house. Without good materials, he will not build a good house. The students do not have sufficient vocabulary.
