高中英语作文教案教学设计（实用20篇）

In recent years, a new type of online shopping is rapidly gaining popularity — group purchasing, which was originally introduced from foreign countries but is now widely accepted all over China. People can buy not only goods, but also all kinds of services on group purchasing sites.

Group purchasing is very convenient, and saves people a lot of money. But it also has some problems. Since group purchasing is nothing more than another form of online shopping, the nature of it is no different from other online shopping patterns. Problems that exist in online shopping also can be found in group purchasing, like deceptive advertisements or poor after-sale services.

In my opinion, we should treat group purchasing as a way of shopping and nothing more. We must be careful not to buy something we don’t need only to follow the fashion.

1、 Today and friends of foreign travel, outside air is very good, people feel very comfortable. We all appreciate the fine girls bicycles. We enjoyed the beautiful nature brought. We happily spent a happy day. 今天和朋友一起出外交游，外面的空气很好，人感觉很舒服。我们骑着自行车一路欣赏鸟语花香。享受着大自然带给我们的无限美好。大家开开心心地度过了愉快的一天。

2、 Today Mailehaoduo clothes, and parents take to the streets is happy, the parents have to pay to buy things. Unlike in their street to buy things they like to take a long time but saw the price, Ha-ha, is really very happy. I love my parents, I too thank them for the care and love. `` 今天买了好多衣服，和父母上街就是愉快，买东西有父母帮付钱。不像平时自己上街买东西碰到喜欢的但看了价钱都要考虑好久，呵呵，真的是很开心。我爱我的父母，太感谢他们对我的关心和爱戴了。`

3、 HOW TO GET HAPPINESS 如何获得快乐

there is no doubt that happiness is the most precious thing in the world. Without it, life will be empty and meaningless. If you wish to know how to get happiness, you must pay attention to the following two points.

First, health is the secret of happiness (the key to happiness). Only a strong man can enjoy the pleasure of life.

Secondly, happiness consists in contentment. A man who is dissatisfied with his present condition is always in distress.

无疑的快乐是世界上最宝贵的东西。没有它，人生将是空虚的而且毫无意义的。如果你希望知道如何获得快乐，你须注意下面两点。

健康是快乐的要诀。唯有身体强壮的人才能享受人生的乐趣。

快乐在于知足。一个不满于现状的人终是处在痛苦之中。

4、 BOOKS 书籍

As is well known, books teach us to learn life, truth, science and many other useful things. They increase our knowledge, broaden our minds and strengthen our character. In other words, they are our good teachers and wise friends. This is the reason why our parents always encourage us to read more books.

Reading is a good thing, but we must pay GREat attention to the choice of books. It is true that we can derive benefits from good books. However, bad books will do us more harm than good.

如众所周知，书籍教我们学习人生，真理，科学以及其它许多有用的东西。它们增加我们的知识，扩大我们的心胸并加强我们的品格。换句话说，它们是我们的良师益友。这是为什么我们的父母终是鼓励我们要多读书的理由。

读书是一好事，但我们必须多加注意书的选择。不错，我们能从好书中获得益处。然而，坏书却对我们有害无益。

In my dream

Last night ,I dreamed I became a very beautiful brid.I dreamed that I was in a forest. In tht forest,there were a lot of animals.Then,an old bird told us,"we have a very beautiful forest,we should therefore protect it from pollution."All the animals agreed with him.

But the second day,people came into our forest.Many animals were caught.The people wanted to build house and parks in our forest.Many old trees were felled.And then suddenly,nothing was left standing.

I was so shocked and then I bursted out crying.I woke up at midnight.It was only a dream.

因此我们应该保护它,免受污染"所有的动物都赞成他.

但是第二天,人们进入我们的森林,许多动物被逮捕.这些人要在我们的森林地上建造房子和公园.许多年老的树木被砍下,然后,突然间,一切都被夷平了.

我很震惊,接着突然大哭起来.我在半夜醒来,原来只是个梦.

world. Once we were together, you always treated me as if I were your dear

brother, so I was grateful to you in my heart. After you leaving, I always

thought of you. Next time we have a chance to see each other, I will say "thank

you" to you. Thank you for your kindness. Now I have got the meaning of my

life.

Although we are in two different places now, we are still together, because

we are always heart to heart. I believe we can see each other again. Since we

are always close friends as well as dear brothers. Because of you, my life is

always so significant. Wherever I am, I will pray good luck for you.

Last but not the least, I hope you can make it and have a bright

future.

一、倾听雨的足音

１、听雨去：

独自一个，带着录音机，观察雨幕，倾听雨韵，感受雨情。

要求做好记录，比如，听雨地点、季节、雨的特点，对雨声雨象的形象描绘，以及自己观雨时的心情，等等。

２、听雨，以小组为单位，把大家听雨所得集中到一起，经过编辑整理，制作课件或者串联起来；课堂展示活动时，由学生上台讲述自己的听雨所得，略加描绘，并展示听雨成果。

说说我听到的雨声──讲述听雨感受。

听听我收集的雨韵。

播放雨的录音。

二、感受雨的诗意

１、展示学生编辑的雨的诗集，并作简评：

可以将他们最成功的页面扫描成图片，再做成 flash 动画，插入音乐，播放。

２、感受雨的情丝：

意境：幽深的小巷，一把油纸伞

字幕：杏花·春雨·江南──雨的情丝

音乐：伴着悠扬的笛音，朗诵，并鉴赏语言美，意境美。

杜甫的《春夜喜雨》：随风潜入夜，润物细无声。……

陆游的《临安春雨初霁》：小楼一夜听春雨，深巷明朝卖杏花。……

白居易的《夜雨》：早蛩啼复歇，残灯灭又明。隔窗知夜雨，芭蕉先有声。

赵师秀的《约客》：黄梅时节家家雨，青草池塘处处蛙。有约不来过夜半，闲敲棋子落灯花。

孟浩然的《春晓》：……夜来风雨声，花落知多少。

王维的《渭城曲》：渭城朝雨泡轻尘，客舍青青柳色新。……

苏轼的《饮湖上初晴后雨》：水光潋滟晴方好，山色空潆雨亦奇。……

朱自清的《春》中描写春雨的一段文字：雨是最寻常的，一下就是三两天。可别恼。看，像牛毛，像花针，像细丝，密密地斜织着，……

戴望舒的《雨巷》：

撑着油纸伞，独自

彷徨在悠长、悠长

又寂寥的雨巷

我希望逢着

一个丁香一样地

结着愁怨的姑娘。

雨，留给人们的不仅仅只是美好的回忆，也有苦涩和无奈，甚至是挥之不去的愁怨。请听作者的愁绪与感慨。

音乐：曲调转为低沉、略带哀怨的萧声曲。

杜牧《清明》：清明时节雨纷纷，路上行人欲断魂。……

李商隐的《宿骆氏亭寄怀崔雍崔衮》：……秋阴不散霜飞晚，留得枯荷听雨声。

杜甫的《茅屋为秋风所破歌》：

八月秋高风怒号，卷我屋上三重茅，

茅飞渡江洒江郊。高者挂胃长林梢，

下者飘转沉塘坳。南村群童欺我老无力，

忍能对面为盗贼，公然抱茅人竹去。

唇焦口燥呼不得，归来倚杖自叹息。

俄顷风定云墨色，秋天漠漠向昏黑。

布衾多年冷似铁，娇儿恶卧踏里裂。

床头屋漏无干处，雨脚如麻未断绝。

自经丧乱少睡眠，长夜沾湿何由彻！

安得广厦千万间，大庇天下寒士俱欢颜，

风雨不动安如山。呜呼！

何时眼前突兀见此屋，吾庐独破受冻死

亦足！老杜之“沉郁”于此可见一斑。

晚唐诗人杜牧虽说才情横溢，可到了江南，面对满眼春色却感叹起历史的烟雨：“南朝四百八十寺，多少楼台烟雨中。”

范仲淹的《岳阳楼记》：“若夫淫雨霏霏，连月不开，阴风怒号，浊浪排空……”，情景交融，渲染出迁客骚人那种去国怀乡、感极而悲的心境。

雨给人们的感觉是多种多样的，也正如此，雨才成为人们歌咏的对象。当人们在观雨时，把自己的感情赋予雨，这时的雨就已经是凝结着作者思绪和情感的东西，成为一种意象。因而，雨又多了一些比喻、象征意义。

“屋漏偏逢连夜雨”，在这种时候，雨在人们心中投下的就只能是生活的阴影了。

“不经历风雨，怎么见彩虹？”这告诉人们，只有付出才会有回报。

三、说说雨的功过

诗人眼中的雨是充满诗情画意的，然而，大自然的雨却是变化无穷的，它可以冲毁桥梁，淹没、破坏庄稼，给人类带来灾难。下面，请站在科学的角度讲述雨的别样情形。

１、讲述雨水泛滥成灾的实例。

２、罗列与雨有关的奇特现象：梅雨、钱雨、泥雨、酸雨等等。说说它们形成的原因以及给人类带来的灾害。

四、抒写雨的情怀

在自己听雨和学习他人文学作品描绘雨的方法的基础上，以一个季节中的雨为意象，结合自己的心情，抓住雨给你的独特感受，写一篇抒情文章。

【范文】

雨的诉说

那天，天下着雨，可是不同往常，天却比较晴朗，我路过一片小树林，树木在雨的洗礼下，更显青葱了。雨滴有的一颗颗挂在叶片上，晶莹地闪着璀璨的光，有的落在两边的土墙上，一滴滴浸开了，大多的落在了土壤里，土地慢慢微润了，我想树根现在正吮吸着这大自然甜美的琼浆，美美地睡熟了吧！

我轻轻蹲下身来，偶然碰到了一颗花瓣上的雨滴，它随着我的食指划到掌心，渐渐滩开，它跳动的光芒暗示我它好像要说什么，于是好奇的我，把耳朵贴近掌心，一阵阵微弱却又欢乐的声音飘进我的耳朵……“哎呦！这是谁呀，把我叫起来了！”雨滴娇娇地说。“不、不好意思，真是对不起！我不是有意的。你会说话吗？”吃惊的我看着它问道。“是的。但是并不是所有的雨滴都会说话的。我是第二次来到人间了，看样变化挺大的，我都不认识了。”雨滴躺在我手里悄声说道。“是吗？你第二次来了！哎，对了，上一次你也来的这儿吗？”我一听这个，迫不及待地问道。“我也记不清了。好像是，也好像不是。我们这些雨滴们住在白云的襁褓里，白云是软绵绵的，好像你们人间的棉花，我们要在其中睡很长时间，为的是储存一些能量，好到人间来用。当一片云彩积满了水滴时，它就会让我们到人间来了。我们到达的地方各不相同，但最后总能碰面。上一次，我和一部分同伴去了苹果林，我落进了土壤里，根一碰到我就吮吸我的浆液，我并不憎恨它们，因为我知道它们要用我的甜浆来结出丰硕的果实，我来的时候看到了树下有一群孩子，我想那结出的红彤彤的苹果是给他们的，大树这样无私地把果实献给那跳着的孩子们，我这一点点又算得了什么呢？孩子是这一个世界的希望，他们好，整个世界也会好的。”

我突然静默了，呆呆地而又充满敬意地望着雨滴，我实在想不到小小的它竟然这样伟大。但是似乎还是按耐不住，我细声问着：“那接着你又去了哪儿了？地底下吗？”“不，我的大部分已被树跟吸收了，剩下的那一部分穿过细土，途中遇到了几个同伴，它们也变得和我一样又小又瘦，我们几个逐渐走到了一个小溪中，这个小溪大部分都是我们的成员，我们沿途滋润青翠的小草，给予繁花以琼浆，我们拜访每一块儿山石，轻抚溪中每一条游鱼，我们唱着，走着，给大自然带来每一点新的音韵……小鸟有时用我们这甘露清凉它们唱完歌后沙哑的嗓子，牛儿马儿常携他们的子孙来喝水，我们也毫不保留地奉献最上等的清泉，看着牛儿马儿在青草地上嬉戏，我们也会乐开了怀。”我仔细地望着这滴小雨滴，不相信这一番话是它说的。我终于明白了它的晶莹，它的无暇，惊讶得一句话也说不出。雨滴看着我惊奇的样子，渐渐又说起来：“其实溪流不是我们的结束，我们最后到了广阔的大海，到了那里我才知道我们的渺小，和大海比起来，我们又算得了什么，在那里我们又将会重新回到天上，等着开始我们的下一次旅行……”

我不再说话了，雨滴也不再说话了，我又轻悄悄地把雨滴托到花瓣上，心里默默祝愿它有一个好的旅程。我轻轻朝它挥了挥手，它也轻轻闪闪光芒。雨已经停了，我想雨滴们又在发挥它们的作用了，其实，雨滴如此，我们的家长、老师等等又何常不是像雨滴一样呢？静静地，默默地，他们奉献着，他们用自己的心温暖着我们一代又一代。远远地，我回望那些雨滴，它们闪着金光，格外明亮……

[“雨”为话题的作文教学教案设计

Nowadays, pets become so close and friendly to our human-beings that more

and more people enjoy keeping them. Pets can bring them a lot of joys and

happiness, because playing with pets is a good way to communicate with the

nature. Besides, pets can comfort old people who live alone. With the companion

of pets, they won’t feel lonely. Nevertheless, I’m not interested in keeping

pets at all. For one thing, keeping pets is bad for environmental protection,

since pets usually make a lot of noise and contaminate the roads. For another,

the virus carried by pets may cause fatal disease. What’s more, sometimes pets

may attack people when they are unhappy. Consequently, we had better not keep

too many pets, so as to ensure our health and security. Besides, those pet

lovers must take some effective measures to prevent their pets from hurting

people and polluting our environment.

导入：

第1段：Some people hold the opinion that A is superior to B in many ways. Others, however, argue that B is much better. Personally, I would prefer A because I think A has more advantages.

正文：

第2段：There are many reasons why I prefer A. The main reason is that ... Another reason is that...(赞同A的原因)

第3段: Of course, B also has advantages to some extent... (列出1~2个B的优势)

结论：

第4段: But if all these factors are considered, A is much better than B. From what has been discussed above, we may finally draw the conclusion that ...(得出结论) オ

In the past two years, my parents took me to travel to many places,

including big cities, small towns, famous mountians and so on. Therefore, I like

traveling and I hope I can visit to many more places. Since then, I hope I can

be a tour guide in the future, so I can travel to many tourist attractions.

Besides, I can meet various people and I think communicating with different

people is interesting, wchich can broaden my field of vision. I hope they can

share their life stories with me so that I can know the general life of a place.

I know it would be a challenging job, but I believe I can do well in my job.

一、创设情境，表达“我的老师”

小学语文课程标准对低、中、高年级学生习作的要求都建立在学生“有兴趣”“乐于”“愿意”“有意识”的基础上，同时我们认为言语交际是有目的、原因和对象的。表达什么——内容；向谁表达——对象；为什么表达——目的或原因。这样学生在习作中才能发挥自己的自主性、能动性和创造性。所以我们在写作之前要创造一个“目的、对象”的氛围，激发学生积极主动地表达。

教师导言：同学们，从你上幼儿园到现在，先后有多少位老师教过你们，请你回忆一下教过你的老师，我们打算开一次以“我的老师”为主题的班会，请大家认真地准备。届时在班会上把自己热爱、熟悉、具有鲜明特点的老师介绍给大家。

二、回忆师情，寻找“我的老师”

学生在习作中只有明确了表达“目的、对象”，才能有习作的动力，才能在习作中有责任感，才能自主地进行写作，才能激发学生积极探究的热情。抓住这个契机，我们设计了“回忆师情，寻找‘我的老师’”，让学生在教过自己的众多老师中选出自己印象最深的老师，介绍给同学们。在这个过程中，同时培养了学生搜集信息和处理信息的能力。

1引导学生回忆老师。

2听歌颂教师的歌曲，朗诵歌颂教师的诗歌。

3同学们找到最理想的“老师”后，同组互相说一说“老师”的基本情况及主要事迹。

4写出习作提纲。

三、指导写法，再现“我的老师”

学生在教师的引导下找到了“我的老师”后，就应该着手习作，让“我的老师”再现在全班的同学面前，使同学们能认识你的老师，了解你的老师。要做到这一点，教师需指导学生的写作方法。

1引言：每位同学都找到了“我的老师”，请大家认真构思，想好习作的内容和语言。

2阅读例文学习如何刻画人物特点，突出人物的形象。

例文：

我的老师

我们的语文老师大约四十来岁，头发已经稀疏了。他的前额布满了浅浅的皱纹，瘦削的脸上戴着一副度数很深的眼镜，显得很有学问。刚看到他的人，总会以为他是一个“老夫子”，教学死板、无味。可是只要听听他的课，保你一定会乐而忘返。

“叮呤呤……”上课铃响了，同学们都坐好了，只有刘锋同学还拿着一个瓶子玩，教师看见了，立刻板起了脸，说：“上课了还玩，没收！”说完，他拿起瓶子走上了讲台。同学们顿时吓住了，老师从来也没发过这么大的脾气呀！谁知，他眼睛环视了一下四周，然后举起瓶子说：“下面根据我手中的瓶子，进行一句话表达。”话音刚落，同学们长长地松了一口气，紧张地心情一下子松驰了，大家都笑了起来，老师也甜甜地笑了，笑声出教室，飞向天空……

他就是这样一个提倡活泼教学的人，难怪“听他一节课，胜读十年书”成了同学们的口头禅了呢。

(1)仔细读例文，想一想作者围绕“我的老师”写了一件什么事？

(2)分组讨论交流，通过阅读例文，你学到了什么？

(3)教师小结：

A.选择的材料要有特点。从“没收瓶子”到巧妙引入教学“一句话表达”，说明了教师的教学艺术别具一格，独具匠心。B结构新颖，例文开始先介绍我的老师外貌，让人感到我的老师老气横秋，一副老夫子像，但接下来的教学行为却与之大相径庭，使人顿感“我的老师”可敬可爱。

(4)动笔习作。

四、交流评议，共享“我的老师”

1个人自评自改。

2小组交流互评互议。

3全班交流：在小组交流互评互议时，教师要认真巡视个别情况，及时发现典型习作，准备在全班交流。也可以让各组推荐一名较好习作参与交流。全班同学互相点评。

4学生再次修改习作。

英语词语之间的语义相似度研究课题作为自然语言处理和计算机人工智能的基础性研究[1?3]，如选取、搜索、分类以及歧义消除等，需要依赖于包含现实世界概念的知识体系[4]。英语词语的相似度是对英语词语之间语义相似紧密程度的度量，在机器翻译、数据信息检索等方面具有重要的实用价值[5]。在不同的实际应用场景中，英语词语相似度具有不同的用途[6]。另外，在构造统计英语词语语言模型的过程中，由于数据分布稀疏导致未登录英语词语的统计信息无法计算的问题[7]，需要进行高相似度英语词语自主选取系统设计。在国内，随着计算机人工智能的不断发展，更准确地进行高相似度英语词语自主选取系统设计引起了很多国内外专家与学者的重视。

文献[8]提出基于朴素贝叶斯的高相似度英语词语自主选取系统设计，首先介绍知网中的英语词语相似度基本概念和体系结构，利用知网的义原层次体系结构计算得到英语词语的义原相似度，计算出英语词语概念的相似度；然后通过支持向量机分类器完成自主选取系统设计。该方法较为简单，但是存在英语词语相似度计算不清的问题，导致在自主选取過程中准确率不高。文献[9]提出基于Corpus库的高相似度英语词语自主选取系统设计，首先构建英语词语语义关联库，利用该库使英语词语空间与关系空间结构化，保存英语词语与其上下文之间的总体信息，通过阅读大量的英语词语语料数据来训练相似度英语词语的相关数据，并对训练过程中涌现的大量英语词语关系进行剪裁，利用朴素贝叶斯分类器完成对高相似度英语词语的自主选取。该方法存在对高相似度英语词语的自主选取时间过长，且英语词语的相似度计算准确率较低的问题。

针对上述问题，本文提出一种基于数据挖掘的高相似度英语词语自主选取系统设计方法，所提系统设计方法可以精确地选取出高相似度英语词语，且选取时间较短，实用性广泛。

1 高相似度英语词语自主选取系统设计

1.1 高相似度英语词语选取系统设计endprint

考虑到人们对高相似度英语词语自主选取系统设计需求的精准性与灵活性[10]，将英语词语的相似度计算结果与数据挖掘特点相结合，设计出一种高相似度英语词语自主选取系统，如图1所示。

本文高相似度英语词语的自主选取系统设计对硬件系统设计不作考量，主要研究软件和算法。

1.2 基于路径和深度的英语词语高相似度计算方法

1.3 基于数据挖掘的高相似度英语词语自主选取

为了能够有效地在网络中挖掘出高相似度英语词语，在处理两个英语词语义项的最短路径与其距离最近公共父节点的基础上，利用数据挖掘将英语词语文本特征选择转换为一个多目标优化问题；然后以英语词语特征维数最少、分类正确率相对最高为选取标准，采用蚁群算法找到英语词语的最优特征子集；最后通过神经网络建立英语词语相似度文本自动分类器。具体描述过程如下：

式中：[σ]为英语词语神经网络隐节点宽度；[c]表示英语词语第[r]个神经网络隐节点中点；[w]为英语词语神经网络输出权值。参数[w，][c，][σ]对神经网络分类起决定性作用，要想获得高性能神经网络，需要对参数进行优化。在此基础上完成对高相似度英语词语的自主选择。

2 实验结果与分析

实验环境建立的PC机配置为：CPU Core i7?4790 3.60 GHz，RAM=4 GB，Windows7操作系统，通过Java语言编写实现。实验过程中设置32个存储节点，每个节点的最大存储容量为1 TB，数据通道为2 000 Mb/s，英语词语文本采集与数据存储均为10 TB。根据参与对比的系统设计使用的英语词语语义资源所收录的英语词语情况，本文从该英语词语测试集中筛选出一些无法计算的英语词语对，最终结果保留10对英语词语用于测试，如表1所示。

从表1中可以看出，[S1]的英语词语相似度计算结果在数值上普遍较低，主要是由于基于Corpus库的高相似度英语词语自主选取系统设计方法考虑众多英语词语特征，加上一些其他干扰因素的影响，从而造成英语词语特征高维向量的相似度普遍偏低；[S2]数值跨度较大，这是由于基于百度百科的高相似度英语词语自主选取系统设计方法通常情况下在某些方面与人工思维没有较好的符合。

利用1.3节中的平衡最大英语词语特征识别率与英语词语特征维数的权值[λ，]对高相似度英语词语自主选取系统设计方法的选取效率影响，如图2所示。

由图2可知，选取参与测试的英语词语数据集为700个，选取英语词语测试数据为200，400，600时对应的高相似度英语词语自主选取系统设计的选取效率，其中，当[λ=1]时，高相似度英语词语自主选取系统设计的选取效率分别为30%，38%和60%；当[λ=3]时，高相似度英语词语自主选取系统设计的选取效率分别为42%，48%和72%；当[λ=5]时，当高相似度英语词语自主选取系统设计的选取效率分别为60%，70%和90%。通过分析可知平衡最大英语词语特征识别率与英语词语特征维数的权值[λ]在区间[1，5]时，本文所提系统设计方法的选取效率最高。

3 结 语

采用当前系统设计方法对高相似度英语词语进行自主选取时，存在选取效率低、选取时间过长等问题。本文提出基于数据挖掘的高相似度英语词语自主选取系统设计方法。通过实验证明，所提系统设计方法可精确地对高相似度英语词语进行自主选取，具有良好的应用价值。

The Origin of Halloween

While there are many versions of the origins and old customs of Halloween, some remain consistent by all accounts. Different cultures view Holloween somewhat differently but traditional Halloween practices remain the same.

Halloween culture can be traced back to the Druids, a Celtic culture in Ireland, Britain and Northern Europe. Roots lay in the feast of Samhain, which was annually on October 31st to honor the dead.

Samhain signifies "summers end" or November. Samhain was a harvest festival with huge sacred bonfires, marking the end of the Celtic year and beginning of a new one. Many of the practices involved in this celebration were fed on superstition.

The Celts believed the souls of the dead roamed the streets and villages at night. Since not all spirits were thought to be friendly, gifts and treats were left out to pacify the evil and ensure next years crops would be plentiful. This custom evolved into trick-or-treating.

万圣节的起源

尽管关于万圣节的起源和旧俗有很多不同的看法，但有一些是被所有人接受的。不同文化看待万圣节总是有点不同，但是传统的万圣节做的事情都是一样的。

万圣节文化可以追溯到德鲁伊教，这是一种爱尔兰、北欧和英国的凯尔特文化，根植于Samhain节的庆祝活动，Samhain节于每年的10月31日纪念逝者。

Samhain节说明夏天结束或者十一月，是一个丰收的节日。在Samhain节会燃起神圣巨大的篝火，标志着凯尔特一年的结束和新一年的开始。一些做法因为迷信被加入庆祝活动中。

凯尔特人相信死者的灵魂会在夜里出没在街道和村庄。因为他们认为不是所有的灵魂都是友善的，所以就把礼物和好吃的留在外面安慰恶灵来确保来年的庄稼可以丰收。这种习俗演变成了trick-or-treating。

In Chinese Spring Festival Gala, the song of Where Has the Time Gone became popular.

The words are so touching that when people listen to this song, many memories will come out.

For our parents’ generation, they married, raised the kids and then watched them become independent, how time flies.

It is just like that they became parents yesterday, and then they become grandparents today.

Time flies so fast that they don’t realize they are old. I am so thankful to my parents, for they do so many things for me.

I want to return their love, so I must become more independent and mature. So that my parents will be less worried about me and can go travel to enjoy their lives. For me, I want to cherish every moment, enjoy my own life and let the time go more slowly.

在中国的春节联欢晚会上，歌曲“时间都去哪儿了”很受欢迎。歌词很动人，以至于人们听到歌曲的时候，很多记忆都涌现出来。

对于我们父母那一代人来说，他们结婚，生孩子，然后看着孩子独立，时间过得真快啊。一切就如他们昨天成为父母，然后今天就成为了祖父母。

时间过的如此的快，他们都没有意识到自己老了。我很感激父母，因为他们为了做了那么多事情。

我想要回报他们的爱，所以我必须变得更加的独立和成熟。这样父母就不用为我操那么多的心，可以去旅游，享受生活。对于我来说，我想要珍惜每一刻，享受我的生活，让时间走得慢些。

World Environment Day is started from 1972, which is established by the United Nations General Assembly for raising global awareness to take actions to protect the Nature. The establishment of World Environment Day shows people’s the cognition and the attitude to the environmental problem, and expresses our human beings’ desire of pursuing the better environment. Every year the United Nations Environment Program proposes a theme, and the 2014 theme of this day will focus on ‘Small Island and Climate change’ and the slogan is “Raise Your Voice Not the Sea Level”.

世界环境日，起始于1972年，它是联合国为了提高全球的环保意识而创建的。环境日的创立展现了人们对环境问题的认识和态度，表达了人们对美好环境的追求渴望。每一年联合国环境规划署都会提出一个环境日主题，而的主题主要着重于小岛屿与气候变化，今年的口号是“提高你的呼声，而不是海平面”。

World Environment Day can be celebrated in lots of ways, for instances, planting trees, doing some recycling, participating the clean-up campaigns and so on. Certainly people can also do something simple, like going to work by bus instead of private cars. I believe if everyone takes environmental actions as a habit, we are doing a big difference for the better environment.庆祝世界环境日的方式多种多样，例如植树，对废物进行循环利用，参加清洁行动等等。

当然，人们也可以做些简单的小事来纪念，比如说不做私家车上班，改乘公交车去上班。我相信只要大家都将这些环保小事当作习惯，我们将会为建造美好环境做出重大贡献。

[高中英语作文：世界环境日

Clothes are so significant in our daily life that we cant live without

them, because they are useful in many ways. For example, clothes could keep us

warm in winter and protect our skin from the heavy sunshine in summer. Whats

more, Clothes make a man just as a saddle makes a horse. Everyday we wear

different kinds of clothes to make ourselves more attractive. Suppose if we wore

the same clothes all the time, our life would be so boring.

As far as Im concerned, I know some kinds of clothes, such as formal

clothes, casual clothes, evening wears and uniforms. In different situations, we

wear different clothes. For example, we wear formal clothes to go to meetings;

we wear casual clothes at home; we wear evening wears to attend evening parties,

and we wear uniforms at school or at work.

Nevertheless, I prefer casual clothes, because they are comfortable. And

they are also very cheap. When I wear casual clothes, I can do a lot of sports.

It’s so cool. By the way, red is my favorite color, since Ive got a white skin.

If Im in red, Ill look kind and friendly. So I always buy red clothes when

shopping.
