    爱护大自然国旗下讲话稿

    尊敬的老师,亲爱的同学们:大家好!今天是6月5日—世界环保日。今天我要演讲的题目是《保护环境卫生,人人有责》。在我们的日常生活中,生活环境是十分重要的,但人们常常不重视这一方面。使清澈见底的小溪变成了肮脏的水沟;郁郁葱葱的大森林变成了落光头发的老爷爷;鸟语花香的村庄变成了山洪爆发的地方……这一切都是由人类的一举一动所造成的。前几日,我到广场上骑自行车,发现不远处的草坪中有许多的白色垃圾,真是不计其数!可见我们的环保意识还不够强。说小一点儿,影响该地区的形象;说大一点儿,这是影响我们国家的形象啊!

    第一篇:国旗下讲话稿幼儿尊敬的老师,亲爱的小朋友们:大家好!我是大三班的小朋友,今天我讲话的主题是:我们的眼睛。小朋友们知道全国爱眼日是哪一天吗?是每年的六月六日。眼睛是心灵的窗户,可我们的眼睛周围却有五个敌人,一号敌人是酒精,所以小朋友要离着酒精远远的。二号敌人是烟,如果身边有人吸烟,你也应该离他远一点。三号敌人是干燥,我们可以多喝水打败敌人。四号敌人是过度日晒,在炎热的夏天,我们尽量不要在太阳底下暴晒。五号敌人是睡眠不足,小朋友们一定要保证充足的睡眠,这样对眼睛才有好处。此外还应当养成良好的用眼习惯,比如不在阳光下看书,不在摇晃的车上看书,不躺在床上看书,看电视、玩电脑的时候不能离得太近,时间也不能超过30分钟,用眼一段时间后,要注意休息,看看远处和绿色的植物,还有一点,就要养成良好的书写姿势,做到指尖离笔尖一寸,胸口离桌面一拳,眼睛里书本一尺的要求。眼睛是我们的宝贝,小朋友们可一定要好好的保护它哦!谢谢大家!!

    Example:One day, a poor boy who was trying to pay his way through school by sending newspapers door to door found that he only had one dime(一角)left. He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.

The story was quite successful in achieving its purpose, and I liked it because it had a clear moral.However, while the moral of the story is clear, the actions of the king seemed pointless to me, because none of the characters in the story learnt anything. For this reason, I think there are better stories that can be used to impress upon people with the need for personal responsibility.Step 8 Pair workExchange drafts with a partner.

As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2.
