习作要求介绍一种物品同学们,在第三单元的学习中,我们认识了最大的哺乳动物——鲸,亲近了机灵可爱的松鼠,也了解了各种各样的新型玻璃。在生活中,我们常常会读到说明性的文章,我们也称之为科学小品文,这样的文章或讲清楚植物的形态特征,或说明白动物的生活习性,或介绍新产品的使用方法,或解释自然现象的形成原因。此类文章兼具知识性和科学性,更重要的是还具有文学性和趣味性,简而言之,理趣兼备。
The study asked students to introduce an article. During the study of Unit 3, we met the largest mammal, the whale, close to the lovely squirrels and learned a great variety of new types of glass. In our lives, we often read explanatory articles, which we also call science essays, which state clearly the morphological characteristics of plants, the life habits of white animals or how to use new products, or Explain the formation of natural phenomena. Such articles are both informative and scientific, more importantly, they are also literary and interesting. In short, they have both reason and interest.
