通过半个学期科技课的学习,我的确长了不少见识。特别是老师给我们讲的袁隆平爷爷发明杂交水稻培育方法的事迹,深深地烙在我的脑海里。当老师讲完“挖缺点”的发明方法叫我们实践时,我真有点儿着急了,因为有的同学已经用这种方法找好了发明课题,而我还没有找到。一天放学,当我闷闷不乐地回到家里时,看见妈妈正在用新买来的不锈钢烧水壶烧开水呢。 Through half a semester of science and technology studies, I really have a lot of knowledge. In particular, what the teacher told us about Grandpa Yuanlongping’s invention of hybrid rice cultivation methods was deeply rooted in my mind. When the teacher told us that the invention method of “digging out shortcomings” was for us to practice, I was in a hurry because some of my classmates had already used this method to find out the problems of the invention, and I haven’t found it yet. One day after school, when I was sullenly back home, I saw my mother boiling water with a stainless steel kettle that she bought.
