One day, Paula and Richard decided to make a kite.
First they went out and found two straight sticks of the same length. They brought them back home and tied them with a piece of string into the shape of a cross. Then they took some string and used it to tie the four ends of the sticks together. Then, they spread some brightly coloured paper over the frame and glued it around the string.They stuck a tail made of paper to one of the corners, and tied a long string to the centre of the kite.
On the next windy day, they took the kite to a hill near their house and flew it.
一天,保罗和理查德决定做一个风筝。
首先,他们出门找了两根一样长的直木棍。他们把木棍带回家,用一根绳子把它们绑成十字形。然后他们又拿了些绳子,把木棍的四个顶端连在一起。然后,他们把一些颜色鲜艳的纸涂上胶水,粘在风筝的框架上。他们将纸做的尾巴粘在一角,在风筝中间系上一根长绳。
在接下来的一个有风的日子里,他们就在家附近的小山上放风筝了。
那是学校第一次组织航模比赛,很早我就来到了学校,随后我们乘坐大客车到了哈工大的一个食堂。在这里,工大的老师首先发下飞机模型的各种组件,然后边放组装飞机模型的录像带,边讲解。我听的非常认真。接下来就是动手组装了,按照程序一步一步地装,很快就组装完成了。我高兴地举着飞机对老师说:“我已经组装成功了!”老师说:“很好,你组装的也很快,可以选进初赛了,过一会儿出去放飞,如果一次放飞成功就可以进入决赛了。”在大部分同学组装完成后,老师把我们领到了体育场,进行放飞的比赛。放飞开始,我把飞机的'螺旋桨顺时针转了一百三十多圈,高举过头,放手,飞机“唰”的一声飞了出去,可又一头栽了下来,放飞失败,被淘汰出局,我心里非常失望和难过。只好看着别人的飞机飞上了天空。
拿着飞机模型回到了家后,我仔细琢磨怎样放飞,为什么我的飞机飞得不远呢?经过再三试放飞,我终于搞清楚了,原来在飞机放飞时,手还要轻轻地向前一送,飞机就飞起来了,然后滑降下来。我高兴极了,我自己组装的飞机也能飞上天了!
这架飞机至今仍摆放在床头前,它是我最为喜欢的一架飞机模型,不仅仅因为这是参加航模比赛的作品,更重要的是我从中学到了很多的知识。
When I was in high school, one of my classmates sit right beside me. His name is ChenLiang. He is my unforgettable person in my life.I remembered my mathematics was just mediocre at that time, but he was extraordinary and excellent in calculating and solving mathematic questions. He often received perfect scores. Of course, I wished I could reach at his level. Since we talked all day long, I asked how he could solve those difficult questions. He was so patient and polite to answer my sometimes ridiculous thinking. Gradually, I built my confidence at mathematics and finally passed the college entrance exam.youtheme
Now, we are apart, but I still remember his great attitude and willing in study. I am so obliged to my classmate, who is my friend always and forever.
翻译:
当我在高中的时候,我的一个同学坐在我旁边。他的名字是亮。他是我一生中最难忘的人,我记得当时我的数学成绩很平庸,但他在计算和解决数学问题方面表现不凡,成绩优异。他经常得到完美的成绩。当然,我希望我能达到他的水平。既然我们谈了一整天,我问他怎么能解决这些困难的问题。他是那么耐心和礼貌的回答我有时可笑的想法。渐渐地,我对数学有了信心,并最终通过了大学入学
现在,我们分开了,但我仍然记得他的伟大的态度,并愿意在学习。我很感激我的同学,他是我的朋友,永远和永远。
制作开始。首先,要制作的是机身,它是连接其它部件的主 干部分。先找来一块3毫米厚的桐木板,再用铅笔在上面勾勒出大致轮廓,然后就可以下刀了。可是在切割的'时候一定注意手法,千万不要大意。在外形确定之后,还要用木锉和砂纸将表面磨光。严格地说,是应该磨成流线型的。但我们的飞机要求不高,因此,磨光就可以了。
接下来,我们将要制作的是飞机上最重要的部件--机翼。飞机之所以能在蓝天飞翔,靠的是升力。而升力的大小关键取决于机翼的形状与角度。所以,制作的时候更要细心。开始步骤和做机身相同,将外形轮廓确定好。接下来,就要精雕细刻了。要用锉和砂纸将两片机翼细细地打磨成流线形。
下一步就是制作垂直尾翼和水平尾翼了。它们是掌握飞机飞行方向的重要部件,所以在制作的时候要特别注意刻度准确。至于制作方法大体和机身相似。
制作之前,一定要准备好必需的工具和用料。如:刻刀、木锉 、胶水、刻度尺等。最重要的是选好木料。可以做航模的木料很多,但最好用的是桐木。
在最困难的一道工序完成之后,组装就显得微不足道了。当然,还应认真对待。因为在成功的同时往往潜藏失败的可能,一 旦不小心失了手,该有多么痛心呢!组装时,先将尾翼固定在机 尾,然后把机翼固定在机身前1/3的位置上。特别要注意的是,机翼应与水平方向成45度角。至此,组装完毕,一架小巧的飞机便在手中诞生了!
也许,初次制作会遇到一些困难,但不要灰心,因为熟能生巧,只要多加练习,就一定会得心应手的。
待到放飞的日子,看着那轻盈的飞机迎风升起,在碧蓝色的天空里自由翱翔,该是多么令人愉快啊!
in my life i have met many people who are really worth recalling. but perhaps the most unforgettable person i ever know is my english teacher. what frequently brings back memories of my school teacher is his special qualities. first of all, he gave us the greatest gift a teacher can offer—an awakening of a passion for learning. he not only led us to an appreciation of the beauty and perfection of english language and literature, but also aroused our great interest in explorating something deeper in this field. second, i was attracted by his lively wit. i remember that we students always anticipated his class with great eagerness because his lecture were humorously delivered, never failing to provoke chuckles or loud laughs. although it is nearly two years since i attended his last class, he is the talk of our old classmates, and i know part of him has already stayed in my heart.
我拿到模型后,就拆开包装袋,把材料拿出来后,按照老师说的先做机翼。拿到工作台板上做,我用里面的四个零件和三根固定零件的小棒,把它们用美工刀修干净,先拿出一根小棒,再把两个零件插在小棒中间的空隙中,再拿出另一根,从零件前端插进去,把最后一根也拿出来,从零件后面插进去,最后,把另外两个零件安装在前两个零件的左右,把小棒插进去,再把这些有空隙的地方用101胶水胶好,用美工刀割下来就OK了,另外一个机翼也是如此。
现在要做水平尾翼了。拿到工作台板上,先把五根小棒和两根大棒拆下来,接着,用美工刀修干净,把三根小棒给插到一根后面的大棒的空隙里,再把一根前面的大棒给插到三根小棒里,最后把两根小棒给插到三根小棒的`左右,再把这些有空隙的地方用101胶水胶好,用美工刀割下来,就行了。
接下来是最重要的一步,把支架拿出来,别看它们小,没有了它们,整个模型就泡汤了。拿出其中一个,先用美工刀修一下,再用砂纸把黑黑的地方磨白,不要磨圆,把另外一个也磨白,然后拿出一个固定支架的东西,把支架放进去,用胶水固定,就差不多了,再把两个机翼给用胶水粘在支架上,高的在前,矮的在后,用美工刀把固定支架的东西的两头给削成一个斜坡,就好了。
最后是组装飞机了。把机身拿出来把随便一端削细,目的是减轻飞机的重量,把尾钩塞进去,钩要朝外,再把垂直尾翼用胶水粘上,把水平尾翼也用胶水粘上,机身后面部分就差不多好了。接下来拿出小的圆的橡皮筋,两个,绕个五六圈,穿过机身,大概在中间的位置,调出固定支架的东西的距离,再把支架放上去用橡皮筋扎牢,之前的斜坡就是为了好扎一点。然后把飞机拿出去,老师在给我们的飞机喷“漆”,喷好后的飞机好粘,趁它还没干,得赶快用一种薄纸粘上,粘在机翼和水平尾翼上,等它干了,把纸多余的地方剪掉就好。最后一步,把螺旋桨安装在飞机的“头”上,用长长的橡皮筋打一个节,节外的绳剪个剩两毫米就行,把橡皮筋绕个三下,把一头套在螺旋桨的钩子上,另一头套在尾钩上,再把螺旋桨转几十圈(最多可转一百八十圈),一松手,飞机起飞喽!
呵,这个飞机自己动手做,好玩吧?你也来玩吧!
