『壹』 講語文八年級上冊的《大自然的語言》的20分鍾的微型課，怎麼講
1，這應該是第二課時。
2，接著上節課的來，既然大家知道什麼是物候、物候學和物專候的作用屬。很自然的想到，影響物候的因素有哪些。讓學生閱讀課文找答案，討論，總結。
3，走進生活，讓學生說說，生活中哪些地方能體現這四方面的因素，加深理解。
4，做練習。

英語演講稿範文
Ladies and Gentlemen, Good afternoon!
I』m very glad to stand here and give you a short speech. Today my topic is 「youth」. I hope you will like it, and found the importance in your youth so that more cherish it.
First I want to ask you some questions:
1、Do you know what is youth? 2、How do you master your youth?
Youth
Youth is not a time of life, it is a state of mind; it is not rosy cheeks , red lips and supple knees, it is a matter of the emotions : it is the freshness ; it is the freshness of the deep springs of life .
Youth means a temperamental predominance of courage over timidity of the appetite, for adventure over the love of ease. This often exists in a man of 60 more than a boy of 20 . Nobody grows old merely by a number of years. We grow old by deserting our ideals.
Years wrinkle the skin, but to give up enthusiasm wrinkles the soul. Worry, fear, self –distrust bows the heart and turns the spirit back to st.
Whether 60 of 16, there is in every human being 『s heart the lure of wonders, the unfailing childlike appetite of what』s next and the joy of the game of living . In the center of your heart and my heart there』s a wireless station: so long as it receives messages of beauty, hope ,cheer, courage and power from men and from the infinite, so long as you are young .
When the aerials are down, and your spirit is covered with snows of cynicism and the ice of pessimism, then you are grown old ,even at 20 , but as long as your aerials are up ,to catch waves of optimism , there is hope you may die young at 80.
Thank you!
