水火箭在上节课就制作完了,这节课,我们要发射水火箭。跟别的小组比起,我们的水火箭显然比他们逊色,但我们还是充满信心地等待着发射……
终于要发射了!我们拿着自己的水火箭,心中泛起一阵阵激动的涟漪。抬头望去,天是那么的蓝,犹如一面镜子,好像地上的景物也能倒映在上面似得。老师拿出发射用的仪器,响亮地说了一声:“第一组!”一阵准备过后,“砰!”霎时水花四溅,同学们纷纷左躲右闪,而水火箭也飞上了蓝天……“哇!真的.飞得起来耶!”同学们激动地说着。又过了几个小组,他们都没有飞得太远。这让我有点紧张:“以我们的水火箭,真的能飞到20多米吗?”正想着,一声洪亮的“第四组!”打断了我的思绪。轮到我们小组了!“砰!”咦?水火箭怎么飞得那么低?“距离——26米。”旁边的同学告诉我们。“唉!”我和雅冰不仅叹了一口气。低着头,默默地捡回我们的水火箭。
“唉!飞得这么近!”我还沉浸在一种失落感中。雅冰安慰我,说:“能飞起来已经很不错了,有一个班的一组水火箭还飞不起来呢!”“也是!”我的心情犹如拨开乌云见太阳,霎时间好了很多。
“瓦屋!”同学们发出一声惊呼。“怎么啦?”我连忙问。“他们的水火箭飞到教学楼去了!”雅冰拉着我的手,“我们也去看看!”“嗯!”来到“坠机地点”,我们不由得感叹一句:“真厉害!”
这是我们的劳技课,它的生动、有趣让我难忘。
我把制作方法看了一遍又一遍,然后迫不及待地找来了材料:一只塑料瓶、一根塑料吸管、一根比塑料管稍长的麦秆、四张三角形的彩色纸和一小块橡皮泥,开始了我的“杰作”。
我先在塑料瓶的瓶盖上钻一个小洞。我一边用手扶住瓶盖,一边用剪刀尖小心翼翼地钻。,眼看快要成功的时候,那圆圆的瓶盖给我来了个“冰上大速滑”。像在和我作对,害得我跟剪刀来了个“亲密接触”,幸亏是有惊无险。我反复地试了一次又一次,可瓶盖总是不停的滑来滑去,我急得像“热锅上的蚂蚁——团团转”。这时,我灵机一动,拿来另一种材料——橡皮泥。我拿出一点橡皮泥,把瓶盖搁在上面,再用剪刀猛地一钻,哈!钻过去了!然后我把吸管插进瓶盖上的`小洞里,并用万能胶粘牢。这个步骤,我不费吹灰之力就完成了。最后,我拿出麦秆,在它的一端粘上四张三角形彩纸,当做火箭的尾翼,另一端用橡皮泥封严,捏作火箭头的形状。等面团干了,我的火箭的“试飞仪式”就开始了,真是“万事俱备,只欠东风”啊!
我把“火箭”套在吸管上,用手使劲一捏塑料瓶,只听“嗖”的一声,“火箭”以“迅雷不及掩耳之势”,一下子飞出了几米远。“终于成功了!”我高兴得一蹦三尺高。
我爱不释手地捧着它,玩了一次又一次。因为它不仅让我感到了劳动最快乐,还提高了我的动手动脑能力,真是“一箭双雕”啊!
二十一世纪飞上太空已不是梦,可上一次太空需要大量的人力、财力等等不说,能源消耗也很大,地球都快挖空了!哪有那么多的能源?作为在二十二世纪生活的我——一名优秀的科学家,终于研制出了“折射光能反应型超级火箭”。此火箭进入太空后根据实际情况组合成一个大型火箭,也可以分离成三个小火箭。
这个火箭是锥头的,总长59.68米,直径3.85米。在火箭的两侧我设置了四个喷射器,而尾部是一个巨大的阳光充能储存舱。光的热度是人类无法想象的,而火箭正好可以运用这股热流,在尾部有一个强化过的玻璃做的一个巨大凹镜。在有光源的时候,火箭会自动接收光源,在凹镜聚焦的原理下,把光射在折射镜上,折射镜再把光射在一面凸面镜上,这样光芒照在一个个光源转型能源机上。这种机器会把光芒转化成巨大的热量来驱使火箭运行,这就不必费燃料了,而且这种光能比燃料用的时间更久,还可以使机器运行性能更强。在每一个光源转型能源机前,又有一根根能源输出管,那样光能就可以转化成热能,然后使机器运转,驱动喷射器。
在太空上,自然会面临着失去地心引力,生活会变得十分不正常。我苦心研究的机器早就解决了这个问题!我美其名称之为“地心引力反转器”。这个机器是存放着两种空间模式:一种是地球,一种是太空。只要将此机器的拉杆往下一拉,火箭内就会变为地球的空间模式;再将拉杠往上一推,就会回到太空的空间模式。最关键的是这个发明不需要任何能源!
“3、2、1,发射!”我发明的火箭成功飞天了,它在冉冉上升,上升……
Wolf, meeting with a Lamb astray from the fold, resolved not to lay violent hands on him, but to find some plea, which should justify to the Lamb himself his right to eat him. He thus addressed him:"Sirrah, last year you grossly insulted me." "Indeed," bleated the Lamb in a mournful tone of voice, "I was not then born." Then said the Wolf, "You feed in my pasture."
"No, good sir," replied the Lamb, "I have not yet tasted grass." Again said the Wolf, "You drink of my well." "No," exclaimed the Lamb, "I never yet drank water, for as yet my mother′s milk is both food and drink to me." On which the Wolf seized him, and ate him up, saying, "Well! I won′t remain supperless, even though you refute every one of my imputations."The tyrant will always find a pretext for his tyranny.
狼和小羊
一只狼瞧见一只迷路失群的小羊,决定暂缓下毒手,想先找一些理由,对小羊证明自己有吃它的权利。它就说:「小鬼!你去年曾经骂过我。」小羊可怜地说:「老实说,我去年还没有出生呢。」狼再说:「你在我的草地上吃过草。」
小羊回答说:「不,好先生,我还未曾尝过草的味道呢。」狼又说:「你喝过我井里的.水。」小羊叫道:「不,我从没有喝过水,因为直到今天为止,我都是吃着母亲的奶汁。」狼一听这话,便抓住它,把它吃下去,便说:「好!即使你驳倒我每一句话,我终究要吃晚餐的!」暴君总有他暴行的借口。
Fox is with the grape
Hungry of the fox see the grape to up hang the radiant and extremely keen grape of a string, saliva direct current, and want to pick to eat, but again
Can not take off.See in a short while, helplessly walked, and his side walk the side oneself to comfort to by oneself say:" this grape have noes familiar, affirmative
Is sour."
This is to say, and the some person's ability is small, and do to not accomplish anything, borrow to say the opportune moment immaturity.

Wolf and egret
The wolf mistake swallowed a piece of bone, very suffered, running about, look for to visit the doctor everywhere.He met the egret, and talk to settle the service fees to invite him to take out the bone, egret to stretch in the wolf's throat the own head, and the 叼 outs bone, then toward to settle the good service fees wolfThe wolf answer says:" hello, friend, you can since the wolf 嘴 take back the head in the peace ground, and the difficult way return the dissatisfied foot, and how and still speak the guerdon?"
This story elucidation, guerdon badly person act charitably, and is a bad person of cognition and does not speak the reputation's innate character.

狐狸和葡萄
饥饿的狐狸看见葡萄架上挂着一串串晶莹剔透的葡萄,口水直流,想要摘下来吃,但又
摘不到。看了一会儿,无可奈何地走了,他边走边自己安慰自己说:“这葡萄没有熟,肯定
是酸的。”
这就是说,有些人能力小,做不成事,就借口说时机未成熟。

狼与鹭鸶
狼误吞下了一块骨头,十分难受,四处奔走,寻访医生。他遇见了鹭鸶,谈定酬金请他取出骨头,鹭鸶把自己的头伸进狼的喉咙里,叼出了骨头,便向狼要定好的酬金。狼回答说:“喂,朋友,你能从狼嘴里平安无事地收回头来,难道还不满足,怎么还要讲报酬?”
这故事说明,对坏人行善的报酬,就是认识坏人不讲信用的.本质。

小男孩与蝎子
有个小孩在城墙前捉蚱蜢,一会儿就捉了许多。忽然看见一只蝎子,他以为也是蚱蜢,
便着两手去捕捉他。蝎子举起他的毒刺,说道:“来吧,如果你真敢这样做,就连你捉的蚱蜢也会统统失掉。”
这故事告诫人们,要分辨清好人和坏人,区别对待他们。

掉在井里的狐狸和公山羊
一只狐狸失足掉到了井里,不论他如何挣扎仍没法爬上去,只好呆在那里。公山羊觉得
口渴极了,来到这井边,看见狐狸在井下,便问他井水好不好喝?狐狸觉得机会来了,心中
暗喜,马上镇静下来,极力赞美井水好喝,说这水是天下第一泉,清甜爽口,并劝山羊赶快
下来,与他痛饮。一心只想喝水信以为真的山羊,便不假思索地跳了下去,当他咕咚咕咚痛
饮完后,就不得不与狐狸一起共商上井的办法。狐狸早有准备,他狡猾地说:“我倒有一个
方法。你用前脚扒在井墙上,再把角竖直了,我从你后背跳上井去,再拉你上来,我们就都
得救了。”公山羊同意了他的提议,狐狸踩着他的后脚,跳到他背上,然后再从角上用力一
跳,跳出了井口。狐狸上去以后,准备独自逃离。公山羊指责狐狸不信守诺言。狐狸回过头
对公山羊说:“喂,朋友,你的头脑如果像你的胡须那样完美,你就不至于在没看清出口之
前就盲目地跳下去。”
这故事说明,聪明的人应当事先考虑清楚事情的结果,然后才去做。

There was a farmer in the Song Kingdom in ancient China. He worked in his field day after day. In good harvest years, he could only have enough food to eat and enough clothing to wear. If the field failed to produce enough crops, he had to go hungry. This farmer wanted to improve his life. But he was too lazy and too cowardly. He always dreamed of having unexpected fortune.
A miracle took place at last. One day, when he worked in the field, some people were hunting nearby. They shouted loudly one after another. Some little animals were running desperately. Suddenly, a hare dashed itself headlong against the stump of a dead tree in his field and died.
That day, he had a good meal.
From that day on, he no longer worked in his field. From morning till night, he stayed by that miraculous stump, waiting for another hare. Will the miracle happen again?
People often use the set phrase “staying by a stump waiting for more hares to come and dash themselves against it" to refer to persons dreaming to reap without sowing.
在战国时代的宋国,有一个农民,每天都很辛苦地在田地里干活.遇到好年景,也不过刚刚吃饱穿暖;要是遇到灾荒,他就得忍饥挨饿了.他很想能过上好一点的日子,可是他太懒,胆子又特小,干什么都是又懒又怕的,总是想着能碰到送上门来的意外之财就好了。
奇迹终于发生了。一天,他正在田里干活,一群打猎的人靠近了。吆喝之声四处起伏,受惊的小动物们没命地奔跑。突然, 有一只兔子,不偏不倚,一头撞死在他田边的树根上。
这天,他美美地饱餐了一顿。
从此,他就不再种地了,一天到晚守着那个神奇的.树根,等着奇迹再次出现。
人们后来就常用“守株待兔”这个成语来形容那些老梦想着不耕种就会有收获的人。
【汉字】守株待兔
【拼音】shǒu zhū dài tù
