谁都有伟大的梦想,而要实现你的梦想,就必须从小时候开始做起。
看到这个题目,我就想:我能不能做一些什么有用的东西呢?
最后,我的视线停在了爸爸的茶叶桶上,我灵机一动,咦!我能不能用茶叶桶做一个笔筒呢?说干就干,我先收集做笔筒用的材料:我到姐姐的房间里找出一些彩纸和彩笔,又跑到客厅在茶几下面找到了一把剪刀……材料终于找齐了。
首先,我把茶叶桶里面的茶叶都倒了出来,用剪刀把彩纸剪成一条一条的彩条;然后,我用胶水把彩条按照彩虹的颜色顺序排列,并粘贴在茶叶桶的外壁。可是,彩条太轻了,风一吹就把它吹散了,费了我好大的力气才把它们整整齐齐的贴起来,可把我累坏了;最后,我把姐姐的笔全都搜出来了,找了几根我喜欢的笔插到笔筒里……就这样,笔筒在我的“精心打造”下诞生了。
“我的笔呢?”姐姐在房间里大喊,我默不作声。“谁拿了我的茶叶?”爸爸现在才发现他的茶叶“失踪”了,我则在一旁偷笑。
他们的笔和茶叶,都为我的.小发明做出了壮烈的牺牲,看着我的小发明我感到无比骄傲!
在这个世界上资讯和科技日新月异,人类依赖着许许多多的器具,使生活更加便利、更加舒适,如果不是爱迪生发明了电灯泡,我们至今还只能使用蜡烛照明呢!人类的历史从使用双手到以机器代替人力,制造各种便利的物品,这些伟大的发明,都是发明家的心血结晶。但仍有些未尽理想,所以发明家每天都努力思考,如何才能创造出更方便、可靠的东西来改善生活。
如果我是发明家,我要发明出一台“时光机”,它可以让人们随时随地到达任何自己想去的地方或是时代,可以再回顾自己年幼时所经历过的美好回忆,它也可以到未来,看看自己的生活过的好不好。只要有一台时光机,无论是充满许多回忆的过去,或者是理想抱负的未来,都能够随心所欲的任由我们人类自由的穿梭与来往。
如果我是一位发明家,我要发明出一辆独一无二的“环保汽车”,完完全全不用消耗汽油的环保车,不但时速可以开到三百公里,又可以折叠后放进口袋或包包,最重要的是它不会制造很多的废气,如此一来,大气层中的二氧化碳也会逐渐减少,地球的暖化现象也不会再恶化了!
如果我们要当一个发明家不是光靠嘴巴说说而已,最重要的是要拟定计划,按部就班的充实知识,使其任何一项说明,都具有深厚的科学理论基础,我想如果当年爱迪生没有这样的精神,在失败中不断改进,也许我们现在还点着蜡烛在昏暗中摸索呢!相信我只要持续不断的努力,把握住每个机会,梦想将不再是遥不可及的幻想,而是成功可期的理想。
我是油田八小303班的李家汇。我的小发明是多功能伸缩黑板擦!在低年级学生值日擦黑板时,常常会出现身材矮小的同学无法擦到黑板最上面的粉笔字。怎么办呢?我想如果能给黑板擦增加一个伸缩自如的杆就可以解决这个难题了。
经过多次试验,我发现用折叠雨伞把比较合适。于是我找来了折叠雨伞把.和比雨伞把略粗的弹簧,还有固定弹簧的卡子。这里弹簧相当于给黑板擦装了一个关节,能使黑板擦各个方向活动自如,并和黑板紧密接触。我先把雨伞把紧紧拧到弹簧里,然后用木螺丝和卡子把弹簧固定在黑板擦的木板上。一个伸缩黑板擦就大功告成了。
但在擦黑板的实践过程中,我发现粉笔末乱飞回迷住眼睛严重影响身体健康,在爸爸的帮助下用白钢皮做一个小盒,固定在黑板擦的下面,这样就解决了粉尘的问题。最后用自粘密封条粘在白铁皮的上面可以避免划伤黑板。
这就是我的小发明多功能伸缩黑板擦,在使用过程中受到了老师和同学们的一致好评。在这里感谢帮助我的班主任汪老师。谢谢大家!
1。 头绪分明,脉络清楚
写好记叙文,首先要头绪分明,脉络清楚,明确文章要求写什么。要对所写的事件或人物进行分析,弄清事件发生、发展一直到结束的整个过程,然后再收集选取素材。这些素材都应该跟上述五个“ W ”和一个“ H ”有关。尽管不是每篇记叙文里都必须包括这些“ W ”和“ H ”,但动笔之前,围绕五个“ W ”和“ H ”进行构思是必不可少的。
2。 突出中心,详略得当
在文章的框架确定后,对支持故事的素材的选取是很关键的。选材要注意取舍,应该从表现文章主题的需要出发,分清主次,定好详略。要突出重点,详写细述那些能表现文章主题的重要情节,略写粗述那么非关键的次要情节。面面俱到反而使情节罗列化,使人不得要领。这一点是写好记叙文要解决的一个基本问题,也需要一定的技巧。如:
One night a man came to our house and told me, "There is a family with eight children。 They have not eaten for days。" I took some food with me and went。
When I finally came to that family, I saw the faces of those little children disfigured (破坏外貌) by hunger。 There was no sorrow or sadness in their faces, just the deep pain of hunger。
I gave the rice to the mother。 She divided the rice in two, and went out, carrying half the rice。 When she came back, I asked her, "Where did you go?" she gave me this simple answer, "To my neighbors — they are hungry also!"
3。 用活语言,准确生动
记叙文要用具体的事件和生动的语言对人、事、物加以叙述。一篇好的记叙文的语言既要准确、生动,又要表现力强,这样才能把人、事描写得具体生动,其可读性才强。试比较下面一篇例文修改的前后效果。
原文:
One day Xiaoqiang was wandering away。 He was soon lost among people and traffic。 He could not find the way back home and started crying。 Just then, two young students who were passing by found him standing alone in front of a shop and crying。 They went up to Xiaoqiang and asked him what had happened。 Xiaoqiang told them how he got lost and where he lived。 The two students decided to take him home。 Mother was pleased to see Xiaoqiang come back safe and sound。 She invited the two students into the house and gave them some money, but they didn't take it。 She served them with tea but they left。
修改后:
The other day, five-year-old Xiaoqiang left home alone and wandered happily in the street。 After some time, he felt hungry so he wanted to go back home。 But he found he was lost among the crowded people and heavy traffic。 When he could not find the way home, he started and crying。 Just then, two young students who were passing by from school found him sanding crying in front of a shop。 They immediately went up to him。
"Little boy, why are you standing here crying?" they asked。
"I want Mom, I go home。" said the boy, still crying。
"Don't worry, we'll send you home。"
And they spent the next two hours looking for the boy's house。 With the help of a policeman, they finally found it。
When the worried mother saw her son come back safe and sound, she was so thankful and she invited the students into her house。 Gratefully, she offered them some money, saying it was a way to express her thanks, but the young students firmly refused it and left without even a cup of tea。
Last Sunday, Jim went out to fly a kite. The kite flew highly in the sky. Jim ran with it happily.
Suddenly the line was broken and the kite flew away. Soon it disappeared. Where was it?
Jim had no idea. So he had to run here and there to look for the kite. At last he saw it on the top of the tree. He tried to get it down. But he couldn’t. He felt sad.
