City cleanness is the symbol and reflection of the civilization of that city. It is obvious that if one comes to a clean and bright city, he will have a comfortable feeling and will be in a joyful mood. On the contrary, a dirty and polluted city may drive him away. So the deanness is very important to a city. But how can we get it?

The key lies in the citizensawareness of the importance of deanness. Citizens are the owners of their city. If everyone dwelling in the city keeps the city clean enthusiastically just as they keep their house clean, then streets will become cleaner and cleaner, buildings brighter and brighter, and consequently, the city will surely become more and more beautiful.

Some measures must be taken to keep our cities clean. For example, we should set a limit to noises and exhaust gases, and invest in the planting of trees and flowers. Moreover, some education and punish ment are necessary too. I believe in the future our city will become more beautiful gardens in a common effort of all the urban inhabitants.

March 12th is Tree Planting Day. This year our school bought enough trees before that day. On that day, we didn‘t had classes. The teachers and our classmates planted trees around our school.

We began to planted trees as soon as we got to school. some students dug the holes. Some students put the trees into the holes.

Some students put the earth back to the holes. Then we pushed the earth hard with our feet. At last we watered the trees as much as possible.

From then on we looked after the trees carefully and the trees grew very well. It made our shcool more beautiful .And How happy we are!

3月12日是植树的一天。今年我们学校买了足够的树在那一天之前。在那一天,我们没有课。我们学校周围的老师和同学们种植的树木。

我们开始种植树木一旦我们到达学校。一些学生挖洞。一些学生把树放进洞。

一些学生把地球回洞。然后我们把地球与我们的脚。最后我们尽可能多的树木浇水。

从那时起我们仔细照顾树木,树木生长得很好。它使我们的学校更美丽。我们是多么快乐!

After investigation, we found that caused the main reason for the increase of greenhouse gases is human activity. Carbon dioxide, for example, before the human society to realize industrialization in the early 19th century, the concentration of carbon dioxide in the atmosphere to 270 parts per million, and in 1988 to rise to 350 PPM. Atmospheric co2 concentration increased there are two main reasons: first, the dramatic increase in population and the development of industrialization, human society, consumption of fossil fuels has increased dramatically, combustion produces a large amount of carbon dioxide into the atmosphere, increase the concentration of carbon dioxide in the atmosphere: second forest reduces the amount of carbon dioxide absorbed by plants use, a speed reduction in carbon dioxide is consumed, also leading to higher concentration of carbon dioxide in the atmosphere. Greenhouse gases than carbon dioxide, such as methane, CFCS (freon), nitrogen oxide and so on also need to increase a different level.

Although there are many uncertainties, it is clear that global warming on climate, rainfall, and the influence of sea level and the resulting impact on human settlements and the ecosystem is extremely complex, must be given the attention they deserve. Think this kind of influence is irrelevant in the long run view is irresponsible.

The main cause of global warming, the atmosphere is destroyed, serious pollution and greenhouse effect caused by global warming could affect global warming will bring to the earth and human complex potential impact, both positive and there are also negative. Such as temperature height, deputy polar regions may be more suitable for human habitation, under appropriate conditions, higher co2 concentration can promote the photosynthesis, which plants have a higher rate of carbon sequestration, lead to the increase of plant growth, namely the stimulation effect of carbon dioxide, which is the positive impact of global warming. But compared with the positive impact, the negative impact of global warming on human activity will be more vast and far-reaching.

经过调查，我们发现引起温室气体增加的主要原因是人类活动。以二氧化碳为例，在人类社会实现工业化以前的19世纪初，大气中二氧化碳的浓度为270ppm，而到了1988年以上升到350ppm。大气中二氧化碳浓度增加的原因主要有两个：首先，人口的剧增和工业化的发展，人类社会消耗的化石燃料急剧增加，燃烧产生大量二氧化碳进入大气，使大气中的二氧化碳浓度增加：其次森林毁坏使得被植物吸收利用的二氧化碳的量减少，造成二氧化碳被消耗的速度降低，同样造成大气中二氧化碳浓度升高。二氧化碳以外的温室气体，如甲烷、氯氟烃(氟里昂)、氧化氮等也不同程度得增加着。

尽管存在着许多的不确定性，但显而易见的是，全球气候变暖对气候带、降水量以及海平面的影响以及由此导致的对人类居住地及生态系统的影响是极其复杂的，必须给以应有的重视。认为这种影响从长远来看是无关紧要的看法是不负责任的。

全球气候变暖的主要原因：大气层遭到破坏，严重的污染以及温室效应全球变暖可能造成的影响全球变暖将给地球和人类带来复杂的潜在的影响，既有正面的，也有负面的。例如随着温度的身高，副极地地区也许将更适合人类居住：在适当的条件下，较高的二氧化碳浓度能够促进光合作用，从而是植物具有更高的固碳速率，导致植物生长的增加，即二氧化碳的增产效应，这是全球变暖的正面影响。但是与正面影响相比，全球变暖对人类活动的负面影响将更为巨大和深远。

因为人的记忆力有选择啊，有的人天生对语言天生敏感，所以记得就快，有的人对历史敏感，记忆历史就比别人快。所以人的记忆力不能一概而论，这是我多年学习的经验，和个人理解。

第一，你不要把英语单词当成中文的象形文字来记，中文的记忆有形象关系，但是单词时无意义的字母排序，背得时候一定要理解英语的发音规律，先要记没个单词的发音，有的发音如tioneror什么的你一定发现了几个字母组合法特定的音，按发音记！

有时候宁肯先记发音！

因为有时候，你甚至能根据发音，你自己就能写出来，何必要背。其实英语的字母单词，不是很规律的，不想拼音的，但还是有一定的规律。

其实背英语单词，不能死记是真的，但是一定要持之以恒，首先要有心理准备，要有自信。

你背英语单词的时候可以边默读便用笔在一张纸上写，就是随便写一些，主要是加深印象。

我的习惯是第一次背时先写5遍/单词，隔天写3遍/单词。过一段时间再重复。这样记虽然慢，但是很扎实。

而且还要注意，背单词应该背词典，就是你背一个词的形式，比如名词，最好翻阅词典，把其他的形式也给背过。这样看起来，似乎比较费脑子，实际上我认为，这样无形中很快，因为你背单词就是要用在阅读上，这样背的话既实用又能无形中体会出英语的变形规律，以后就会背的很快乐。

英语背单词，实际取决于你已经背的单词量。

不是英语专业的人，但是愿意分享我的经验，希望你能背得越来越轻松。

At college, i missed my parents a lot. as the term was drawing to an end, i eagerly looked forward to going home. and i planned to do a thousand and one things during the vacation. above all, i wanted to help my mother with housework. i also wished to read many hooks which my teachers had recommended. however, at home, my mother would never let me do anything. she completely deprived me of sharing her work. as soon as i opened a book to read,she would sit down beside me and ask me about all kinds of things at the college. to please her,i told her one thing after another,and soon i forgot all about books. even when i was actually reading,she would, now and then,insist that i should eat an egg or drink a cup of tea. when i left home at the end of the vacation, not a thing in my plan had been carried out. but i felt very happy. i believed much more deeply than before in the old saying: home, sweet home. there’s no place like home!

Generation gap, simply is the idea of the thoughts of the people of different age groups for gap caused by the psychological distance. Just as a ditch, separated by the generation of people, affect the understanding and communication between two generations. But in the new century, the generation gap exists not only between the generation and the next generation, and separated by 10 years, 8 years in age between people, even between senior and junior in the university, there will be amazing. People often say, the generation gap is the trace of time, the pace of change. In that case, a generation gap is natural, but there is no generation gap is not natural, so, the generation gap phenomenon is easy to be understood.

代沟，简单地说就是不同年龄层次的人因思想观念上的差距造成的心理距离。就象沟一样，隔开了一代一代的人，影响两代人之间的理解和沟通。但是到了新世纪，代沟不仅存在于上一代与下一代之间，而且在年龄相隔10年、8年的人们之间，甚至在大学的高年级与低年级之间，都会有令人惊叹的明显差异。人们常常说，代沟是时间的痕迹，变革的脚步。如此看来，出现代沟是自然的，没有代沟反倒是不自然的，所以，代沟现象也容易被人理解。 但代沟毕竟是困扰交流与沟通的难点，而且容易增加形成偏见和歧视的可能性，代沟两侧的人轻则互不理解，重则抱有敌意，所以我们也要通过种种途径作各种努力来跨越代沟、填平代沟。其实，代沟也并不是一种物理存在，而是一种心理存在，接触，可以让代与代之间曾经断裂的心理联系接续起来，从而达到交流的顺畅和相处的和谐。

承代沟的客观存在，心平气和地对待代沟，这样不仅有助于自己，也有益于他人。

代沟往往是心理认识的偏差导致的。人们选择信息角度的不同，决定了有人着眼于变化和差异，有人着眼于不变和相似。所以人们不能接受上代或下代与自己这一代人的差异，往往与知性的选择性有关。

上次，我的英语月考成绩低得可怜，因为我没复习阅读的部分。所以这次我决定一雪前耻。考试的前几天，我每天回到家，就打开书，不断的重复阅读那几段要考的故事，希望可以有好成绩。

终于等到了考试的这一天，我的神经不停的抽搐着，不时的绷着，我留了一身冷汗，看着老师发着考卷，我吞了口口水，看着考卷传了下来，我颤抖着双手，拿着考卷，笔拿了起来，那枝笔似乎比平常来得要重，我用那只沉重的笔，开始了这场令人神经紧绷的考试。

每写完一大题，我的情绪就越紧张，因为那阅读的部分在我写完一大题，就会离我越近。危机逼近，我的皮随着也紧了起来。我在心里不断的念念有词：“要来啦！要来啦！它要来啦！”但是当我望向时钟，心里疑惑着：“怪了！过了这么久，考卷也即将要写完了，怎么还不见噩梦来袭呢？”

“叮─当─叮─咚”，洪亮的钟声刚好响起，我即时写完了！但是我的天敌却始终没有出现，难道说这次月考没有“阅读”这一大题？看来我真是白紧张了！不过，往好的方面想，这次的考试简单多了，也就是说，拿满分的机率很高。我放下了心中的大石，心想着：“这就是塞翁失马，焉知非福”吧！

当全球气候变暖时，世界发生了巨变。

南极，冰雪融化，人类感觉将要处于冰水之中，这是人类自食其果。北极的霸主北极熊，也因全球变暖而逐渐走向灭绝。一直熊妈妈向小熊递来一把剪刀，熊宝宝好奇地问：“妈妈，用剪刀干什么呀?”妈妈以命令的语气回答：“快剪毛，再长这么厚的毛会被热死的!”小熊天真的望着妈妈：“我们住在冰天雪地里，怎么会热呢?这是我们的外衣，没有它会受冻的，不能剪!”熊妈妈的语气中带点悲伤和叹息：“现在全球变暖，在不适应，恐怕就走向灭亡了!”

全球变暖，北极熊无法找到食物，甚至食用小熊，这是被逼无奈呀!人类应当对自己的行为进行深刻的反省，可是，当全球变暖时，人类还无法意识到自己的错误!只知道冬天不再受寒风的折磨，温度上升了，寒冷已离去，只顾着眼前利益，可不知道以后将远离那洁白的雪，原本应在寒冬中开放的花。

当全球变暖时，希望人类早已意识这以后果。趁早弥补，阻止这一切的发生!
