The Dragon Boat Festival is one of three major Chinese holidays, along with the Spring and Moon Festivals. Of the three, it is possibly the oldest, dating back to the Warring States Period in 227 B.C. The festival commemorates Qu Yuan, a minister in the service of the Chu Emperor. Despairing over corruption at court, Qu threw himself into a river. Townspeople jumped into their boats and tried in vain to save him. Then, hoping to distract hungry fish from his body, the people scattered rice on the water.

端午节与春节和中秋节并列为中国三大节日。这三个节日中，它可能是最古老的一个，可以追溯到公元前227年的战国时代。这个节日是为了纪念楚国的大夫屈原，他因为对朝廷的腐朽****感到绝望而投河自尽。镇上的人纷纷冲上船去救他，却没有成功。后来大家把米撒到水里，希望把饥饿的鱼群从他的躯体边引开。

Sakura is the Japanese name for ornamental cherry trees, Prunus serrulata, and their blossoms. Cherry fruit (known as sakuranbo) come from a different species of tree.

Sakura, a well-known and ubiquitous symbol of Japan, are represented on all manner of consumer goods, including kimono, stationery, and dishware. Cherry blossoms are an enduring metaphor for the ephemeral nature of life, and as such are frequently depicted in art. There is at least one popular folk song, originally meant for the shakuhachi (bamboo flute), titled "Sakura", as well as a number of pop songs. "Sakura" is also a common Japanese female name.

Sakura is indigenous to the Himalayas and east Asia. Some trees can be found in China and Korea but the largest number and variety of sakura, more than 305 species, can be seen in Japan. Many of them were artificially hybridized or grafted by the Japanese many centuries ago.

"On the other hand, in China, cherry blossom is the symbol of feminine dominance, female beauty and sexuality. Additionally, the cherry blossom is the Chinese symbol of feminine principle and it also symbolizes love in the language of herbs. Interestingly, cherry blossom is the flower of the April in China, whereas in Japan, it is wisteria." Spring flowers of Japan

Japans most beloved variety is the Somei Yoshino. Its flowers are nearly pure white, tinged with the palest pink, especially near the stem. The flowers bloom, and usually fall within a week, before the leaves come out. Therefore, the trees look nearly white from top to bottom. The variety takes its name from the village of Somei (now part of Toshima in Tokyo). It was developed in the mid- to late-19th century at the end of the Edo period and the beginning of the Meiji period. The Somei Yoshino is so widely associated with cherry blossoms that jidaigeki and other works of fiction often depict the variety in the Edo period or earlier; such depictions are anachronisms.

Other categories include yamazakura, yaezakura, and shidarezakura. The yaezakura have large flowers, thick with rich pink petals. The shidarezakura, or weeping cherry, has branches that fall like those of a weeping willow, bearing cascades of pink flowers.

Annually, the Japanese Meteorological Agency and general public track the sakura zensen, or Cherry-Blossom Front. Nightly forecasts follow the weather segment of news programs. The blossoming begins in Okinawa in January, and typically reaches Kyoto and Tokyo at the end of March or the beginning of April. Then it proceeds north, arriving in Hokkaidō a few weeks later. Japanese pay close attention to these forecasts. They will go to parks, shrines and temples with family and friends and hold a "flower viewing party" known as hanami. Hanami festivals celebrate the beauty of sakura, and for many, it is a chance to relax and enjoy the beautiful view. Hanami custom in Japan dates back to many centuries ago. It is witten in Nihon Shoki that the Hanami festival were already held in the 3rd century.

Most Japanese schools and public buildings have sakura trees outside of them. Since the fiscal and school year both begin in April, in many parts of Honshū, the first day of work or school will coincide with the cherry blossom season.

Li Yan, an engineer, was born on February 9, 1965 in Beijing, China. After he graduated from Qinghua University in 1987, he made an important decision in his life. He decided to go to the United States for his further study. After four years hard work, he mastered new management ideas an advanced technologies in computer field. In 1992, he got his doctors degree. In 2008, he made another decision that to return to his motherland and started a company. However, his wife and daughter had got used to the American way of life, so they still stay in the United States. But they still can meet frequently, because of the convenient transportation, and his wife and daughter often visit him in holidays.

Nowadays, there are many kinds of activities for people entertaining in their leisure time, especially in holiday, such as climbing a mountain, having a picnic, holding a party and so on. However, these recreational activities have its advantages but also bring some harmful influences to people’s lives.

First, to some extent, these recreational activities enrich people’s lives. Those who take part in different activities will not be easy to feel lonely or boring in their leisure time and live wonderful lives instead. Second, taking part in some group activities is a good form to strengthen friendships. For example, many students will hold a union to collect their old classmates or friends in winter holiday so that they have a common time to communicate with each other. Last but not least, such activities like climbing a mountain provide a good chance to do exercise.

However, these recreational activities also bring some problems at the same time. For one thing, taking part in too many these activities will increase the burden of themselves or their families because it is inevitable to spend some money in holding these activities. For another, some recreational activities have potential harm for participants’ health, particularly staying up all night, drinking and smoking.

Therefore, in my opinion, we have to make a careful consideration before we take part in these recreational activities.

拿到英语试题不知道从哪里下手吗?那么下面这套英语写作流程对你会有一定的帮助。

一.审题。

拿到题目后，手中拿铅笔，手脑眼嘴并用，开始审题。看题目的要求是什么，要点是什么，特殊要求是什么。譬如你是叫李华，还是随便一个名字? 要议论文还是记叙文?对分几段写有无要求?等等。诸如此类的硬性要求信息，都最好用铅笔划下来，以免出错，也许你一开始会记得，可随着时间的流逝，你会不会因紧张而遗忘这些信息呢?还是小心为妙。边看最好边张嘴默读，这样就不会遗漏或忽略任何一个字了。

二.草稿。

有的同学怕出错，全文都打草稿再誊写，我姑且认为不太可取，毕竟考场时间宝贵，即使我有四十分钟时间写作文也不敢贸然这么做，更何况考场时我们留给作文的时间往往一再被压缩。有的同学不打草稿，我认为更不太可取。一来容易出错，二来边写边想思维不连贯，即使思维连贯也无法审词酌句，展现自己最好的一面，容易后悔。

草稿怎么打?

1.结构就是你打算分几段写，每段都写什么?哪段转哪段承哪段起合?心里都要是有谱的。

2.关键词：结构拟定后，迅速在草稿纸上写下自己这篇作文可能用到的一些关键词。包括一些漂亮的词和自己可能会忘记的词。主要是动词和名词。

譬如一省作文题： 假设你的名字是李华，亚洲冬季运动会将在你居住的地方举办，现招募志愿者。你希望成为志愿者。申请信的格式已经写好了，你直接写内容就可以。你的个人情况：年龄性别学历，个人条件。英语好，爱好体育，擅长交际，乐于助人。承诺提供最佳服务。

关键词就是学历、爱好、擅长、乐于、承诺，和你对这篇作文初步构思时想到的一些词。先把这些词(指词的英文表达)写在纸上。有一些词的拼写，譬如学历，可能你本身就记得不是特别清楚，这时一定要在开始写作文前先把它写下来，以免一会因干扰而遗忘。

可能看到聪明这个关键词时，你最初写下的往往是clever，再仔细想想，你是不是又想到了smart,deligient好多词，挑个漂亮和合适的用吧。再比如转折，你写了but，这会再想想，是不是又有一堆表示转折的词在你脑里打转呢?挑一个吧。千万别用but.

3.句式：词写下来了，其实你构建这篇作文的建筑材料就到位了，下步就是要把它们盖成漂亮的作文。先用最普通的陈述句把它们在头脑中过一遍，然后看看都能改成什么句式。能不能把一句陈述句改成问句?能不能用上一个双重否定句?能不能用一个主语从句套定语从句的长句?能不能用一个插入语?等等。把你高中三年的英语积累展示出来。在草稿纸上同样标注。

三.正式写。

这样的草稿打完后，就要快快写了。注意，英语作文的卷面简直太重要了，一定要把字写整齐，写大。没有把握的词和句子不用。别忘了遵守你最初用铅笔划下的题目的规定。

四.检查。

注意，最最重要的一步来了。尽管很小心，可是我们写英语作文还是会犯下很多错误。单词拼写的，大小写的，等等。这些错误会极大破坏我们在阅卷老师心目中的形象，一定要坚决誓死消灭。即使时间再紧，请务必留下1——2分钟检查作文的时间，消除隐性错误。

需要说明的是，英语的开头和结尾是最关键的，尤其是开头。基本上，不跑题，遵守题目要求，一个漂亮的开头，一个还过得去的结尾，2-3个高级词汇，1-2个漂亮的句子，加上整齐的字迹，作文的分就不会低了哦。所以，精心为你的作文想个漂亮的开头吧。

Shanxi Province got its name due to its location to the west of Taihang Mountain. Shanxi neighbored on Hebei, Henan, Shaanxi and Inner Mongolia & Autonomous Region. It is located to the east of the Yellow River, and is also known as Hedong. Shanxi belonged to Jin State in Spring and Autumn Period, so it is abbreviated in Jin. Shanxi occupies an area of 156,000 square kilometers (about 60,000 square miles) and has a population of over 32 million, including its minority ethnic population. Its capital is Taiyuan City.

When to go

Being at a high altitude, Shanxi Province has a cold and dry climate and has an annual rainfall of between 400-600 millimeters. The province is also frequently plagued by sandstorms, especially in the spring, so it is often useful to bring along both sunglasses and a hat when visiting. Generally speaking, the provinces climate is the best between May and October.

History

Shanxi is one of the birth places of Chinese civilizations with a long history and traditional culture. As early as one hundred million years ago, the ancestors of the Chinese lived and propagated in this region. Legend tells us that the Yellow Emperor, founder of the Chinese nation, once lived in Shanxi for a certain period. Today, many Neolithic sites from that period can still be seen dotted across the vast expanse of the province.

What to see

Shanxi is endowed with an abundance of cultural sites from its long history. Most of the ancient structures were built before the Liao and Song Dynasties. So it is the reason why Shanxi is often called the Chinese Ancient Architecture Museum. The more obvious of these include: the Buddhist wonder of the Yungang Grottoes in Datong City, the ancient city of Pingyao which was listed as a World Cultural Heritage site by UNESCO in 1997, the oldest and tallest ancient wooden pagoda in China, the Wooden Pagoda of Yingxian County and the remote Shuanglin and Jinci Temples, which are well worth the long journeys for the visitors.

Of course, there are a number of natural magnificent and beautiful places that can also be seen in Shanxi. The most famous of them include Wutai Mountain with the longest and most prestigious history in the four most well-known Buddhist holy lands of China, the whistling rage of the Yellow Rivers Kettle Spout waterfalls (Hukou Waterfalls) and one of the Five Sacred Mountains in China - Mt Hengshan.
