课文的第一自然段写太阳远的特点,作者先用有关太阳的传说开头,使文章生动有趣,引人入胜;接着指出太阳离我们有三万万里远,为了说明三万万里究竟有多远,作者进一步运用了两个大胆新奇的假设,一是步行到太阳上去需要三千五百年,二是坐飞机到太阳上去需要二十几年,这样既给人留下了比较清楚的印象,又使人读来兴味盎然。
课文在介绍太阳热的特点时,先用大火球作比喻,形象地反映出了太阳的形状及发光、发热的特点;接着指出太阳的表面温度有六千度,六千度该有多热?作者通过钢铁碰到它,也会变成汽加以说明,引起了读者强烈的联想,从而使六千度变得生动形象、炙手可热。
How is everything going?There is a plan about next lesson.
The lesson will be held in our school,it will begin at 7:00a.m.The lesson mainly about learning the poems in Tang Dynasty.As we all know,the poems in Tang Dynasty are very popular,they are one of the Chinese culture's symbols.So it is a good way to help you learn Chinese better.In addition,you should learn a little the history of Tang Dynasty before.In the lesson,you also can know more about Chinese culture by this chance,and I'm sure you must be interested in the rare Chinese culture.
