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!
To see a world in a grain of sand,
And a heaven in a wild flower,
Hold infinity in the palm of your hand,
And eternity in an hour.
一沙一世界,
一花一天堂,
手中即无限,
永恒亦短暂。

儿时所徜徉的街头巷尾,总有这样一些人:他们衣衫单薄,在北风呼啸中守在一个冒着热气的锅炉旁,向过往的行人喊道:卖茶叶蛋喽,香喷喷热腾腾的茶叶蛋喽!他们的声音正如同他们的手一样在不停颤抖,冻僵的脸因为北风的猛烈渐显皲裂,即使饥肠辘辘也决舍不得吃一个茶叶蛋。他们大半是乡下的,因家里实在无法过活才到城里卖茶叶蛋为生,而乡下人,多半淳朴而老实,不善与城里人打交道,所以生意总是很寥落。
虽然从小在母亲“不要吃路边摊上的东西,不干净”的训诫中成大,可在我的记忆中那里却是我所感受到的除父母外的全部温情。基于父亲对诗人杜甫的热爱,我从小也在父亲的熏陶下读了不少的杜诗,他诗中的那些淳朴劳苦人民的形象,总让我联想起那些站在北风中瑟瑟的身影。我时常在放学后不愿回家,流连于街道,哪怕是远远观望橱窗中精致的礼品与各式点心,也总让我心满意足,而除此之外,我就只喜欢在那些摊边小贩身边来来往往,久而久之,几个记性好的人就认得我了,却始终没和我说过什么话。我在冬天尤其喜欢挨在他们身边坐下,母亲工作比较晚,回家后也不会太过关心我放学后的事,她是一个很给孩子自由的'妈妈。因此我便常将她的训诫抛到耳后,用我攒的零花钱买茶叶蛋吃,以此作为我的晚餐。于是我跟他们逐渐熟络起来,常听他们谈起家中情况,我心中暗自与我家相比,这才知道平日里所抱怨的生活艰难实在不值一提。小贩们很热心,总特地拿一条板凳出来给我这样一个不买什么东西却老爱干坐着的小姑娘,尤其是一位大婶,她说她女儿跟我差不多大,所以对我特别好。我坐在冒出的热气的锅边,感觉比在家中烤火盆还暖和。我以为生活会一直如此,总在不经意间让人感受到暖暖的温情。
然而一切并非如我所愿,小学快读完之时,父亲已在另一座大城市里买了新房,我们举家搬迁,离开了这个小镇。新家很宽敞,一应生活用品也全改了样,更符合大城市的格调。我经常会寻找那熟悉的身影,可惜各种各样的商店占据了我心中小摊的位置。我多次在同学的陪伴下走进一家家咖啡屋,它们正处于我记忆中的街头巷尾。然而一切又是那样的不同,服务员客气的微笑与礼貌的用语,还有咖啡屋别致而有情调的格局,总让我觉得少了些什么。我心里在期待,期待有一天可以回到小镇,再一次坐在那热气中与大婶大伯们闲聊。这样的机会终于来了。有一次母亲回小镇走亲戚,我陪她一起回去了。然而结果却令我大失所望,茶叶蛋的摊铺早已消失得无影无踪,取而代之的是与大城市一样别致优雅的咖啡屋。
虽然期待落空,我却始终怀着希冀。朋友总说咖啡比那破茶叶蛋高级了,你怀念那干嘛?我却知道茶叶蛋在我心中并非仅仅是“茶叶蛋”,而是在它的汁香流溢中蕴含了一种别样的温情。
美食DIY课程开始了,我们学习做包子,虽然我不爱吃,但这项技能挺有用的,能让我们的动手能力增强等。
我表哥说小升初面试的真题中有番茄炒鸡蛋怎么做?说不定我考试时有包子怎么做呢?好了,废话不多说,来看看包子怎么做吧。
第一步,准备好食材与工具,面粉五百克,糖二十克,酵母十克,泡打粉十克,清水或温水适量,盆一个,蒸格一个,香菇一百克,青菜三百克,盐二十克,菜板一个,擀面杖一根。
第二步,将青菜与香菇洗干净,烂菜叶扔掉,因为香菇蒂硬的像石头,所以扔掉,一定要洗干净。
第三步,将洗干净的菜与香菇切成小颗粒,不能太大,要小一点,大约半个小指甲盖儿那么大。
第四步,在青菜粒与香菇粒中放盐,这样能把他们的水分排出去。
如果不排,蒸好后的包子里就会全是水。
等一两分钟用手把青菜与香菇中的水分挤捏干,放在旁边备用。
第五步,把面粉倒在盆中,先把面粉做成像盆的样子,然后把酵母、糖都倒在中间,面粉上洒一圈泡打粉,加入适量清水,揉成像雪花、白棉布一样的样子,不要觉得粘手,多揉一会儿就好了。
第六步,继续加水揉面团,重复的一直揉,直到面团不干不湿,面光手光盆光,这时的'面团就像一只又大又肥的白鹅的身体,十分有光泽。
第七步,将面团搓成长条状,分成大小相等,十分均匀,大约40克的小剂子。
第八步,将小剂子擀成中间厚,四周薄的圆片,然后在中间放入做好的香菇青菜香菇馅料,一手拿着皮,一手捏出褶皱,最后封口,后面的以此类推。
第九步,每个包子大约隔两手指的距离,放在蒸锅里蒸熟。
第十步,大约10分钟后,大功告成。
可以吃了,我一口咬下去十分的美味,我也很开心,哈哈哈哈。
Nowadays, many famous university campuses have become one of the popular tourist attractions. It has been shown on TV and on the radio that every year thousands and thousands of middle school students visit Tsing Hua University and Peking University and other famous universities in China. In the place far away from the capital city, the local students also visit the universities famous in their own province.
So far as the present situation is concerned, is it a good or bad thing to open the university campus for tourists? Different people have different opinions. On one hand, some people argued that it is a good thing for the students to visit the famous university campus in that it can enable the middle students to get more information about the university and they can have enough time and opportunity to prepare themselves with the chance to get into the university. On the other hand, some people hold a negative view about this phenomenon. In their opinion, the public tourism will have negative effect on the universities because it will not only do harm to the environment but also to the intellectual atmosphere.
In my opinion, the tourism to the universities is not a good thing. The campus is mainly a place for study. With the increasing tourism on the campus, it will ruin the spiritual atmosphere in this learning field.
首先,提纯范文 “谋篇布局”及结构模板。
第一段:提出问题或现象。Nowadays, … … have become one of the popular … …. It has been shown on TV and on the radio that … ….
第二段:正反列举人们的看法。So far as the present situation is concerned, is it a good or bad thing to … …? Different people have different opinions. On one hand, some people argued that it is a good thing for … … in that … …. On the other hand, some people hold a negative view about this phenomenon. In their opinion, … … will have negative effect on … … because it will not only do harm to … … but also to … ….
第三段:摆明自己观点。In my opinion, … … is not a good thing. … … With the increasing … …, it will ruin … ….
其次,提纯范文“段落写作”。
段落写作分为统一性,连贯性和完整性三方面。
统一性(unity:段落开头的主题句应该做到不可太宽泛,也不可太具体,做到有较强的概括性才能使下文做到有的放矢的展开。范文第二段首句以设问的方式提出一个问题is it a good or bad thing就有很强的概况性。下文自然会一方面从好的方面说明,另一方面从坏的方面说明。
连贯性(coherence:关联词是使文章段落之间相互连贯的必要条件。范文中nowadays, on one hand, on the other hand, in one’s opinion即以“启承转合”递进的顺序是文章条理清晰,层层展开。
完整性(completeness:以设问句“So far as the present situation is concerned, is it a good or bad thing to open the university campus for tourists?”开头,这是平时较少运用的段落写作方式——设问法。“On one hand … …. On the other hand, … ….”是段落写作分类列举法的典型用法。
再次,提纯范文“句子写作”。
1. It has been shown that … …
类似句型:It is known to us that … …
It is said that … …
It is reported that … …
It is controversial that … …
2. “… … Tsing Hua University and Peking University and other famous universities … …。”——并列句。并列句是简单的复杂句。但其运用方法并不简单,注意练习并接句的使用,会使句子显的更加饱满。
3. enable v. 使…能够
I gave him full directions to enable him to find the house.
4. in that = because
表“因为”的连词还有since, for, as,如:
The boy was absent because he was ill. = The boy was absent since he was ill.
此句以我们常用的人称开头,句式简单,我们可以通过把since提前改变句式,如:
Since the boy was ill, he was absent. 句式多样化。
最后,提纯范文“措辞”。
1. attraction n. 具有吸引力的事情。
2. thousands and thousands 成千上万的
形容“多”的表达方法:millions and millions
a multitude of
a great deal of
a large amount of
plenty of
many a
3. “some people argued that … …”中的“argue”并不是“讨论,辩论”的意思,而是“认为”。
I argue that … …
I maintain that … …
I claim that … …
I insist that … … = I think that … …
I hold that … …
I assert that … …
I assume that … …
4. negative adj. 否定的.,相反的
hold negative view = hold opposite opinions
5. phenomenon n. 现象
social phenomenon 社会现象
natural phenomenon 自然现象
6. intellectual adj. 聪明的= intelligent, bright, clever
(选词策略:使用最近所学的单词,如intellectual > intelligent > bright > clever
在分析并掌握范文之后,我们需要运用范文知识练习仿写。笔者运用2005年12月范文中的模板结构仿写了2006年12月的四级作文,以供参考:
1. 许多人喜欢在除夕夜看春节晚会
2. 但有些人提出取消春节晚会
3. 我的看法
Nowadays, the Spring Festival Evening has become one of the popular topic and attractions during every traditional New Year’s Eve. It has been shown on TV and on the radio that every year thousands and thousands of Chinese people appear to be accustomed to enjoying the sights and sounds of a brilliant feast, while gathering with their beloved family.
However, an increasing number of people have voiced different opinions towards it. So far as the present situation is concerned, is it a good or bad thing to cancel the Spring Festival Evening? Different people have different opinions. On one hand, some people argued that it is a good thing to amuse the audience in that it is composed by a numerous adequate programs, such as the emotional song, the graceful dance, the funny short sketch, the amusing comic dialogue, the delightful magic, and the marvelous acrobatics and so on. On the other hand, some people hold a negative view about this phenomenon. In their opinion, the Spring Festival Evening will have negative effect on the family harmony because it will not only do harm to having the talks between family members on the Spring Festival Eve but also to enjoying the gourmet meal in a fancy restaurant.
In my opinion, the Spring Festival Evening is a good thing. It may not remain a must for all people, but it can bring us a strong sense of festivity and serve as an alternative among the variety of holiday activities. With the increasing audience of the Spring Festival Evening, it will ruin a distinctive culture during the Spring Festival vacation.
