我有许多喜欢的节日，比如：端午节、重阳节，但我最喜欢乞巧节。因为乞巧节是由牛郎和织女而来的，下面我就来给你讲一讲乞巧节的由来吧。

有一天，牛郎碰见一头生病的老黄牛，牛郎见它生病了，就悉心照料。

有一天，牛郎碰见一群织女，并喜欢上了其中一个织女，那个织女也很喜欢牛郎，他们过上了幸福的生活。这事被王母娘娘知道了，又把织女抓上了天。

老牛说话了：“等我死了以后，把我的皮做成一双鞋，你就可以腾云驾雾了。”老牛死了以后，牛郎把老牛的皮做成了鞋，飞上了天去找织女，可是却被王母娘娘头上的簪子变成的银河挡住了去路。牛郎在对面守了许多天，最后王母娘娘也被感动了，所以王母娘娘只在七月七日这一天，让牛郎和织女见面。织女心灵手巧，女人都乞福自己也能心灵手巧。

这就是乞巧节的来历。

初三英语作文：Travels on Holidaysin China

Nowadays, more and more people like to travel in their holidays. The other day I read a report about the ways people spend their holidays. It is reported that in recent yiars several new holiday habits have been developed. Among them, the most interesting one is the growth of the so-called holiday camps.

From the report we can see that in 1990,40 percent of people stayed at home for holidays. But now the proportion has reduced to 9 percent. More people go out for fun. The proportion of camping and traveling abroad was increasing steadily, from 10 percent in 1990 to 38 percent in 2002, and 12 percent in 1990 to 26 percent in 2002 respectively. People enjoy the fresh air, clean Water and green hills when they go camping in the suburbs. In 1990,38 percent people enjoyed going to the seaside while in 2002 only 27 percent prefer to go there. What great changes!

Why did those changes appear? I think there are several reasons. First, it’ s because people can afford traveling. Second, people prefer to pursue a high-quality and colorful life. Third, their attitudes to relaxation have changed. Less people want to save much money by leading a simple life. In short, people’s living standard today has been rising greatly.

[Travels on Holidaysin China初三英语作文

紧张了一学期的学生们迎来了寒假。但对初三的考生们来说，距中考还有短短的几个月，寒假是一个查漏补缺的好机会。在这短短的三周时间里，怎样制定复习计划，怎样在有限的时间里提高效率?

通过这学期的几次月考，发现了学生们普遍存在的一些问题，针对这些问题在寒假里进行针对性的训练是很有必要的。

1、单词掌握得不错，却不会在填单词的句子中运用，失分很多。

2、能记住重点句型，但不会灵活变换句式。

3、了解语法，却不会做时态填空。

4、能读懂短文，却做不对选项。

5、知道如何写作文，却在写作时漏洞百出。

6、选择填空马马虎虎。

7、听力很差，失分很高，尤其是分析题。

所以，针对存在的问题，为避免以后重现类似错误，为复习考试奠定一个好的基础，特做计划如下：

1、加强听力训练。希望同学们每天听一套跟中考要求一样的听力材料。就像中考听力一样要求自己。听完后核对答案。看看失分在什么地方。然后合上书再听一遍，锻炼自己的听力。坚持听上一假期，肯定有收获。

2、培养良好的写作习惯。每天背上一篇好的范文，写上一篇类似的作文，用上里边的好词好句，对于连词成句部分，不妨每天写上5个连词成句，摸索里边的规律，在做这个题的时候，先看看里边有什么词组，什么句型，这样写起来就不会摸不着头绪了，集中练上一段时间会有提高的。

3、养成阅读的好习惯。由于阅读在考试中的比重很大，所以要加大阅读的力度。每天都要练习两个阅读两个完形。做完后核对答案，对做错的题分析原因，对里边出现的生词或短语要记录下来，有必要的要背过，以此来扩大自己的词汇量。此外，要限定时间以此来提高阅读的速度和能力。

4、强化重点题型训练。针对单选题和完形填空题错误较多的情况，同学们最好在寒假里把老师上课讲的专项练习好好看一遍，把老师讲的重点例题弄懂弄明白。每个学校都有一本复习指导的书，把书吃透了，里边的题弄明白了就可以了。题要精不要太多。把自己常错的题写在一个纠错本上，经常看看巩固巩固。

5、增加词汇量。有的学生平常的词汇量很少，在做阅读完形的时候看不懂文章，短时间增大词汇量不太容易。但假期是个好机会，可以集中来记忆。可以把几本书拿来把上边重要的黑体字部分的四会单词分期分批地记忆，每单元的重要词组也要背过。再配合着题做一些词型变换的题，学会灵活运用。

6、做几套中考模拟题。要重视往年中考题，在假期里给自己规定时间来做几套中考模拟题，做做往年的中考题有特别的作用。因为每年的中考命题难度相对稳定，风格相对一致，做中考题有助于同学们摸清中考命题的“套路”，明确复习方向，最后找出自己的不足之处，作为下一次的努力目标。

In peoples life, food and clothing live line, deficiency may not be all. Especially the food, it is closely connected to each of us, is our daily necessities. As the saying goes, the meal is not to eat so hungry. So we should pay attention to food safety. Food safety is increasingly concerned topic in our life, one of the active management of the ministry of commerce and industry at the same time, also often implement the food inspection work.

The so-called food safety, is the food does not contain any harmful substances to human body. If food spoilage or containing toxic substances, will bring harm to our body and even life-threatening. Food safety is about peoples life and health. Inferior food greatly endanger peoples health, light diarrhea diarrhea, or poisoning coma, moreover may cause death. Indeed, food safety is directly related with the health and quality of life of the masses. Schools around there are many small shops, the inviting "gourmet" from the fragrance, the classmates to withstand the snack temptation, you, me one yuan to buy a lot of snacks, the results some buy snacks classmates because bought not health food and have loose bowels.

Remember once I saw a news on TV: a famous yogurt brand for some reason, the expired yogurt repackage again, also good food quality supervision administration found in time, otherwise the consequence is unimaginable. Look at these factories, how hard, in order to market competition, regardless of the health of consumers.

The above examples are enough to prove that the importance of food safety, food unsafe events caused great influence to peoples life, food regulators have also been attaches great importance to this problem. Believe that relevant departments can seriously, strict management, give you a rest assured food environment. We, as a primary school student, as a member of a society, we should also be constantly improve the self-protection ability and the ego to protect consciousness, render and do our work with regulators.

在人的生活当中，衣食住行，样样缺不得。特别是食品，它是与我们每个人紧密相连的，是我们每天的必需品。俗话说得好，民以食为天，一顿不吃饿得慌。所以我们更该关注食品安全。 食品安全是我们生活中日益关心的话题之一，工商部门积极管理的同时，也常常实施着食品检查的工作。

所谓食品安全，就是食品里不含任何对人体有害物质。如果食品变质或者含有毒物质，就会给我们身体带来危害甚至危及生命。食品安全关乎人的生命健康。劣质食品极大得危害了人的健康，轻则拉肚子腹泻，重则中毒昏迷，更有甚者可能会引起死亡。的确，食品安全直接关系着群众的身体健康和生活质量。学校周边有许多小店，那诱人的“美食“发出阵阵香味，同学们抵挡不住零食的诱惑，你五角，我一元地买了许多零食，结果有些买零食的同学都因为买了不卫生的食品而拉肚子。

记得有一次我在电视里看到了一个新闻:某一知名酸奶品牌因为某种原因，把过期的酸奶重新包装了一遍，还好食品质量监督管理局及时发现，不然后果不堪设想。看看这些厂家，多么毒辣，为了市场上的竞争，竟不顾消费者的健康。

以上事例都足以证明食品安全的重要性，食品不安全的事件给人们的生活造成了很大的影响，食品监管部门也一直很重视这个问题。相信有关部门能够严肃处理，严格管理，给大家一个放心的食品食用环境。而我们作为一名小学生，作为社会的一份子，我们也应该要不断提高自我保护能力和自我保护意识，以及尽自己的绵薄之力配合监管部门工作。

For the young people, it is very important to have ambition, they need the motivation to move on. But most of them are just talking about the ambition and never take the action. The action is as important as the ambition. On the one hand, ambition sets up the goal for a person to fight. Without ambition, no one can be successful, ambition is just like the light in the dark, it leads people to see the bright future.

On the other hand, action helps people to realize their dreams. Sometimes, action even is more important than the ambition. Everyone has the ambition, but the action makes them different. The one who just keeps thinking and not to take action will never be successful. As the saying that no pain, no gain, it reminds people to take action. So we need to have both ambition and action.

对于年轻人来说，有雄心壮志是很重要的，他们需要动力来前进。但是他们大部分人只是嘴上说说，从来不行动。行动和决心一样重要。一方面，决心为人定下目标去奋斗。没有决心，没有人能够成功，决心就如黑暗中的灯光，引导着人们来看光明的未来。

另一方面，行动帮助人们实现他们的梦想。有时候，行动比决心更加重要。每个人都有决心，但是行动才会有所作为。谁只是想想而不采取行动的话，是不会成功的。正如有句话说没有付出，就没有收获，这告诉人们要采取行动。因此我们既需要决心，也需要行动。

“对潇潇暮雨洒江天，一番洗清秋。渐霜风凄紧，天河冷落，残照当楼。……”对着雨儿，不免愁绪不断。

白日里金乌高照，艳阳似火。傍晚时分，夕阳已将天边的残云烤得火红，罔若绽放的鸡冠花，血红欲滴。我孤单一人默默走过喧闹的操场，但内心却是万种忧愁。我不希望别人看到我的另一面，因为他缺乏热情，充满忧虑，他不知道如何生活，他没有探求新知的欲望，他太累了，也许他不该存在罢。

一边踱步，一边思索。走在静谧、充满芳草香味的绿荫过道，心情好似平伏了一些。蓦然回首，残阳的余晖洒满大地，洒满周围的人的身上，却为何将我孤单的身影拉得斜长？

时光如同流水，静静地逝去，然而对于我——世界的弃儿，时间仿佛停止流逝，我想也许是因为我的心已如止水一般，再也无法经历暴风骤雨。

夜色无情地吞蚀着周围的一切，然而我却十分欢喜。因为只有在夜的世界，我才能尽情地释放。追逐着风儿奔跑，遥望着苍穹中美丽的星河，坐在树旁，与树儿谈笑风生。有月的夜，还可以于皓洁的月光中独舞。不我并不孤独。因为还有斜影、清风、明月、老树、虫儿……它们能为我作陪。它们能毫无顾虑地与我游玩。在夜的怀抱中，我得到太多的幸福。“夜之骄子”，这是我最得意的名字。

然而，当第一滴雨自九霄飘落，在灯光下散射出一道道冰冷的寒意，灵魂彻底崩溃了，美好的愿望为何总不能实现？为何对我这般苛刻？难道我的要求过分了吗？

强忍着对天意的愤怒，冲出教室，伫立雨中，仰天长啸。脸上湿湿的，好像眼泪，任凭冰冷无情的雨将我融化。惆怅失落，无语泪流。雨帘之中，周围的一切模模糊糊，恍恍惚惚。

……是雨，却有雾一般的缥缈；是雾，却有雨一般的缠绵。这样的雨夜，我的忧愁也如雨一般不断……

XX is my good friend. She’s in Class1, Grade4 of Tianjiao Primary School. She’s a model student. She’s clever and she’s helpful, too. She often helps teachers and young students at school. She is good at Chinese, maths, English, arts and crafts, music and so on. She has a lot of hobbies. She likes painting and drawing. And she likes listening to music, having picnics with her parents. Oh yeah, she likes fishing, too. But she doesn’t like playing basketball, football, table tennis or volleyball. XX is the best friend of mine. I like playing with her. We always work together and help each other.

A dream is to a man what wings are to a bird. With a dream in the deep hearts core， a man is spontaneously driven to hitch his wagon to a star.

A dream is an inexhaustible source of energy that keeps our enthusiasm burning， and kindles our desire to enhance our spiritual cultivation， refine our character， and upgrade our quality of life. A life without a dream is like a bird with broken wings， confined to a cage and oblivious of what lies beyond the range of its vision. On the contrary， a man with a dream is like a warrior armed with ambition， foresight and gallantry， daring to step into an unknown domain to make a journey of adventure. It is dream that adds fullness， variety， and spice to our life and makes it worth living.

I have a dream. It is a dream that is deeply rooted in human nature. I dream that one day people of all origins can live in harmony and peace without being discriminated against or persecuted. The bounty of the earth can be shared by every single human being. Mutual respect will guarantee the existence and continuation of the diversity of customs and cultures. Love， sympathy， and cooperation will alleviate the sufferings and disasters inflicted upon our fellow men. Respect for basic human rights will put an end to social injustices and evils. When my dream comes true， all men will be truly equal， happy， and free.

Time came slowly to the Qingming time.

The afternoon of April 3rd, our school organized a class five and class together to worship the martyrs cemetery. Walking into the cemetery, looking around, surrounded by mountains, quiet and silent. Occasionally, there are several birds singing, but they also disperse quickly. Most of the students were lowering their heads, wondering what they were thinking in silence. I sighed with a sigh and thought: it was a long time away from the time of the war, and the soldiers who died for the country were fading away. How many people could remember them? Everyone left with a strain of white flowers, looked up at the distance. Looking at the tall marble statue of the martyr, there was a feeling of admiration in mind, and my thoughts went to that distant age. Those young girls who are still in flower season have sacrificed their lives in the cruel war. Did they ever regret when they died? At that moment, they thought of their parents at home, or the security of their country, or just such a departure?

The worship of the process is very simple, but the atmosphere is dignified. No matter what, what is on your mind at this moment, everyone is silent and soundless. Finally, we put the paper flowers in front of the stone tablets and leave them together. The whole process is somewhat solemn and heavy. Returning to school, my mind is always relaxed and depressed. Whenever I think of that stone tablet and think of the soldier who is sleeping underground, there will be a lot of sadness and weakness. Todays life is because of them, we can live so happily.

Qingming Festival is the traditional festival of our nation. At this time, everyone will pay homage to their loved ones or martyrs. In this Qingming Festival, we can do too little or too little. Only hope that we can use a sincere heart to face our elders and martyrs.

We know very early, she is a very good classmate. She has a round face, the face with a pair of round eyes, a little flat nose, a big mouth. She is my best friend and YanWenYi Chen Weijun.

Her more advantages and disadvantages are more, I said she first: the advantages of her learning seriously, love reading, home of the book she was almost over, but also helpful.

Her weakness is: jealousy is very strong, she has what others cant have, such as a YanWenYi let her to buy a copy of one yuan notebooks, she agreed, then asked: "what cover do you want?" YanWenYi said: "want to candy house." She is angry of say: "I dont bought for you." Then she ran. YanWenYi said to me: "I want to buy, like her, she is jealous." I say to YanWenYi: "dont be angry, I help you to buy it." She also has a downside is that greediness, such as when we were playing at a time, I brought some candy from home to eat, she chased me to: "give me, give me a little." I think she is too tired, just give her some helplessly, as long as it is her good friend to take something to eat, she would have stretched out his hand to, scared I couldnt take sugar.

This is my friend, a sweet tooth - Chen Weijun and helpful friend.

我们很早就认识了,她是一个挺不错的同学。她有一张圆形的脸，脸上镶着一双圆圆的眼睛，稍微有点塌的鼻子，一张大大的嘴巴。她就是我和颜文意的最好朋友陈维俊。

她的优点比较多，缺点也比较多，我先来说说她的优点：她学习认真，爱看书，家里的书几乎被她看遍了，而且还乐于助人。

她的缺点是：嫉妒心很强，她拥有的东西别人不能拥有，比如有一次颜文意让她帮忙买一本一元钱的笔记本，她答应了，便问：“你要什么封面?”颜文意说：“要糖果屋的。”她就生气的说：“我不给你买了。”说完她就跑了。颜文意对我说：“我要买的和她一样，她就嫉妒了。”我对颜文意说：“别生气，我帮你买。”她还有一个缺点就是嘴馋，比如一次我们在玩的时候，我从家里带了一些糖去吃，她就追着我要：“给我一点吧，给我一点吧。”我觉得她太烦，就无可奈何地给她了一些，只要是她的好朋友带东西吃，她就会伸手要，吓得我都不敢带糖了。

这就是我的朋友，一个有馋嘴又乐于助人的朋友——陈维俊。

The Spring Festival is very important to Chinese people。In the past，people could not often have meat，rice or other delicious food。They could only eat these during the Spring festival。So every year they hoped that the Spring Festival would come soon。Now，although people‘s life is much better，and we can eat the delicious foods everyday。People still like the festival。Because most people can have a long holiday，and we are free to go on a trip or visit our friends or have parties with our family。In the evenings，we can have a big meal in the restaurant or stay at home with family and watch the TV programmes。

I like the Spring Festival very much。How wonderful the Spring Festival is！

春节是中国人民非常重要。在过去，人们不可能经常有肉，大米或其他美味的食物。在春节期间他们只能吃这些。所以每一年他们希望春节很快就会来的。现在，虽然人们的生活要好得多，我们可以每天吃美味的食物。人们仍然喜欢这个节日。因为大多数人可以有很长的假期，我们可以去旅行或访问我们的朋友和我们家有聚会。在晚上，我们可以有一顿大餐在餐馆或呆在家里和我的家人看电视节目。

我非常喜欢春节。春节是多么美妙！

烟里有一种对人身体不好的东西——尼古丁。

一枝香烟中的尼古丁可以毒死一只小白鼠，25g的香烟里的尼古丁可 毒死几头牛，40至60毫克纯尼古丁可以毒死一个人。

尼古丁的危害也是相当的大，它可以引起胃痛或其它胃病;还会使人引起心律不正诱发心脏病;严重的还可能引起癌症的爆发。

香烟是隐藏在我们身边的隐形杀手，是大家所应警惕的。

据科学家测定，烟草中含有数百种复杂的化学成分，大部分对人体有害，其中焦油、尼古丁、酚类、醇类、酸类、醛类等40种是有毒和有致癌作用的物质。烟在点燃后，所产生的烟雾，包含了烟草中所有的化学成分，同时比烟草本身又增加了一些有害物质，如一氧化碳和烟焦油等。这是因为除烟草本身外，在制成卷烟的过程中，要在原料中加入一些可可、甘草、糖、甘油、乙二醇等调味、湿润、产香、助燃物质。这些添加剂虽然本身无害，但在燃烧过程中却起了变化。例如，在鼠背涂上可可燃烧后产生的烟油，可长出皮肤瘤。甘草中的甘草酸在燃烧后，与其他成分化合，可生成有致癌作用的多环芳烃。糖与烟草一起燃烧后增加了焦油量，而糖燃烧后的产物是烟中的一个重要致癌物。甘油和乙二醇在燃烧后的物质，不但可能使吸烟者患膀胱癌，而且所产生的丙烯醛可抑制气管和纤毛分泌物从肺内排出，从而增加患气管炎和肺气肿的机会，并使患有这两种病的人病情加重。

烟对人的危害是多么大啊!所以我们不能吸烟。杜绝吸烟，造福后人。
