如何保持健康的英语作文70字【一】

我们埋着头,或学习,或工作,那近在咫尺的美却悄然溜远了。而当我们退一步时,当我们与美保持适宜的距离时,便会领略到不一样的美!

什么?你问:“距离为何产生美呢?”我想,大概是由于近距离可以让人宏观地把握事物,而远距离能带来未知的神秘,引发了人们的美好幻想吧!

在美国登月之前,中国早已流传着嫦娥奔月等关于月亮的美丽的传说。然而,当宇航员们带回来几块冰冷的石头时,当宇航员们发回几张月球真实“面貌”的照片时,那些美丽的`传说便荡然无存了。从此,每当人们说起月亮,脑海中只会浮现出一个荒凉的星球,而人们不再会想象月球上会有嫦娥、玉兔与广寒宫了。

远观月亮,能使人们产生了美好的遐想;近观月球,人们知道的却只有荒凉的星球。这便是距离的奇妙作用! 那么,在我们的生活中,又如何去退出来去被忽略的美呢? 美,此刻的距离便是人与人之间的距离!在这个物欲横流的社会里,人们的心灵总被功名利禄紧紧裹住,以至于无法体会到身边的美,所以,我们要与功名利禄有着适宜的距离:当我们不再是为家长、老师的夸奖和奖励而学习时,我们会发现,书本中的知识是如此有趣;当我们放慢上学的脚步时,我们会发现,街边的苍翠的大树多么富有活力;当我们不再那么冷漠地对待生活时,我们会发现,世界是多么的温暖……生活中处处皆有美,人们缺乏的只是保持与美有着适宜的距离而已。

当我们的心灵得到解放时,当我们与万物保持着适宜的距离时,我们会发现天空,是能给了我们翱翔的天空;我们会发现大地,是能养育万物的大地;我们会发现海洋,是孕育了最初的生命的海洋…… 让我们一起退一步,保持与美有着适宜的距离,那么,身边的美就会纷纷呈现出来的!

如何保持健康的英语作文70字【二】

苹果为什么削皮后放有一定的时间会变成褐色呢?我在书本和网络中寻找答案,得知个中原因是苹果里含有一种氧化酶,当苹果削去皮后,果肉与空气相遇,在氧化酶的催化下果肉中的氧化物质便被氧化,导致变色。

怎么样才使削皮后的苹果不变色呢?为此,我做了几个实验。

首先,把苹果果肉切成薄片,在其中的一片上滴上几滴柠檬汁,第二片涂上盐水,第三片什么都不涂。

大约10分钟过去后,第三片开始变浅咖啡色,其他两片还保持原来的鲜亮洁白。半个小时后,第三片果肉从咖啡色变成了黄褐色,其他两片仍然保持原来的颜色不变。

实验表明了柠檬水和盐水可以让去皮后的\'苹果不变色。为什么柠檬汁和盐水有这个功效呢?原来柠檬汁里含有维生素C,维生素C有还原性;盐水能把空气挡在外面,果肉接触不到空气,自然不会变色了。

不管是用柠檬汁还是盐水,其原理都是阻止去皮苹果接触空气而被氧化变色,这就是保持苹果不变色的绝招!按照这样的原理,要使苹果去皮后不变色,就要想方设法阻止果肉接触空气。

为了进一步印证这个原理,我又做了第二次实验,去三片果肉片,一份暴露在空气中,一份泡在凉开水中,一份涂上橙汁,结果第一片还是在约10分钟后变色,第二份约30分钟后开始变颜色,第三片过了24小时还是没有变色。可见涂上橙汁可以防止去皮的苹果变色,原来橙汁跟柠檬汁一样含有维生素C,也能阻止苹果果肉的氧化。

因此,要想使苹果去皮后不变色,我们可以采取多种方法,只要是能够阻止空气与苹果果肉接触,都能达到目的。

如何保持健康的英语作文70字【三】

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.

如何保持健康的英语作文70字【四】

教师要与学生保持“距离”日常教学时,教师有目的多找学生谈话沟通,学习上常提醒,生活中多关心,让学生消除心理上的畏惧感。这样,在学生心目中,教师既是可尊敬的师长,又是可信赖的朋友。因此,学生就会把老师的表扬看作是对自己的鼓励,信心倍增;老师的批评是对自己的鞭策,及时改正;尤其是对学生病时的一句问候,更让他感到温暖。

所谓“疏远”,就是有意识的和学生保持距离。甚至人为的制造距离。与“拉近”相比,“疏远”学生往往更能体现出一名教师的管理艺术。作为一名教师,应该像一支部队的统帅,要为了战斗的胜利,不计较一城一池的得失,要站在战略的高度做学生的思想工作,及时的预见到未来可能出现的情况。谓“下棋看五步”意亦如此。

我班有个学生常常以“天才”自居。他聪明过人,基础扎实,但常骄傲自大,不可一世,导致其思想表现和学习成绩总是大起大落。我开始制造“疏远”了:大型活动的组织者中

消失了他的名字;各科老师也不怎么提问了,好像一下子淡忘了他!几个星期后,强烈的自尊心驱使这个学生低着头走进了我的办公桌前。

每一个学生都是复杂、多变的个体,因而评价学生的对错必须有多个标准,要用发展的眼光来看学生,摒弃“从小看到老”、和“一俊遮百丑”的静态的眼光和思维方式。要对那些犯错误的学生采取一些科学的管理艺术,让每个学生从一个个错误中走出来,科学地对待犯错误的学生,使他们有机会在纠错中成长。

教育是塑造人的艺术,教师应当善于处理与学生的“距离”。与学生保持何种“距离”最佳,我们借用古人的一句话:“增之一分则太长,减之一分则太短。”果真如此,则善莫大焉。
