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。

随着科技的发展，人与人之间的距离越来越短了，因为有各种通讯工具的维系，彼此之间越来越近了，但是烦恼却也越来越多了。这是为什么呢？
相信大家都很熟悉“触龙说赵太后”的故事。从史书记载来看，这位赵太后在国家危难时临危不惧，主持朝政，接见外来使臣时应对自如，并不是一个蛮不讲理、目光短浅的老太太。但在让长安君去别国做人质这件事上，她为什么会说出“再有议此事，老妇必唾其面”的话呢？究其原因，由于关系到自己的小儿子，她没能保持适当的距离从大局上看待此事。这也是“事不关己，关己则乱”“当局者迷，旁观者清”的道理所在。
画家作画时，常常画几笔便退后几步瞧瞧再画。有人觉得奇怪，站得近不是看得更清吗？为什么要退后呢？其实这样做是很有必要的，退后是为了更好地观察画的整体布局和整体色调。同样道理，对于涉及自己或亲近的人的事情，人们往往容易失去分寸，乱了阵脚。此时如果后退几步，保持距离再作思考，不失为一种必要的理智行为。
如果没有忧伤，快乐便显得单调惨白。情感的宝贵之处在于丰富多样，因距离产生的伤感便是其中最动人的一种。在中国史上，思念家乡、怀念故人的诗显得最为缠绵婉转。如范仲淹的“酒入愁肠，化作相思泪”，王维的“独在异乡为异客，每逢佳节倍思亲”，李清照的“此情无计可消除，才下眉头，却上心头”等诗句，使人心弦颤动，情难自已。这些作品都是诗人与亲人久别时衷情难诉而写下的佳作，可见距离也是一种酿造情感美酒的发酵物！保持距离不失为一种调节情感的好方法。
人生难免遇到烦恼，遇到困难，我们在和困难中苦苦挣脱不开，倒不如退后几步，保持适当的距离，那个时候你一定会看到另外的风景，看到属于你的海阔天空。

如何保持健康的英语作文60字【四】
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

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.

I attended Jack's birthday party tonight. After dinner, Jack gave cigarets to our boy students present.
At the important moment, I stop them and told them the bad effects of smoking: firstly Smoking is a waste of money and it's greatly harmful to our health. And it can lead to fires easily. So we should not smoke at all.
But it seemed helpless and they wouldn't listen to me. Somebody even said that body and health belonged to themselves and it's up to them to decide whether to smoke or not. I told him calmly, "Even if you have the right to harm your own body, but it doesn't mean that you have the same right to harm others'."
At last, they agreed with me, and some students said that they would never smoke any longer.
For the next one hour, we danced and sang happily, and nobody did smoke again.I felt very happy that my classmate all understood the harmness of smoking.
