children know their task and as everybody around them focus the attention on

study, so they are affected by each other and have the strong desire to

Thanksgiving is an ancient festival American original people, is also the American family reunion holiday, so the Americans brought Thanksgiving always feel warm. Thanksgiving Day is the most truly American of the national holidays in the United States (holiday), the early history of the United States and is most closely connected. The early settlers of Massachusetts originated in Plymouth. These people were called pilgrims in the UK, because of their religious reform of the Church of England is not completely satisfied with, and the king and the Church of England for their political repression and persecution, so the pilgrims from the Church of England, went to Holland, then decided to move to the other side of the Atlantic that desolate land, hope in accordance with the wishes of their religious freedom in life.

1962年9月,“五月花号”轮船载着102名清教徒及其家属离开英国驶向北美大陆,经过两个多月的艰苦航行,在马萨诸塞的普利茅斯登陆上岸,从此定居下来。第一个冬天,由于食物不足、天气寒冷、传染病肆虐和过度劳累,这批清教徒一下子死去了一半以上。第二年春天,当地印第安部落酋长马萨索德带领心地善良的印第安人,给了清教徒谷物种子,并教他们打猎、种植庄稼、捕鱼等。在印第安人的帮助下,清教徒们当年获得了大丰收。首任总督威廉·布莱德福为此建议设立一个节日,庆祝丰收,感谢上帝的恩赐。同时,还想借此节日加强白人与印第安人的和睦关系。1621年11月下旬的星期四,清教徒们和马萨索德带来的90名印第安人欢聚一堂,庆祝美国历史上第一个感恩节。男性清教徒外出打猎、捕捉火鸡,女人们则在家里用玉米、南瓜、红薯和果子等做成美味佳肴。就这样,白人和印第安人围着篝火,边吃边聊,还载歌载舞,整个庆祝活动持续了三天。

In 1962 September, "May flower" ship loaded with 102 pilgrims and their families to leave England to North America, after two months of hard sailing in Plymouth, Massachusetts ashore, settled down. The first winter, due to lack of food, cold weather, disease rampant and overworked, the settlers died more than half. The second year spring, the local Indian tribal chiefs, Masaso de led the kind-hearted Indian, gave the Puritan grain seed, and teach them to hunt, planting crops, fishing etc.. With the help of the Indians, the pilgrims had a good harvest. The first governor William Bradford has proposed the establishment of a festival to celebrate the harvest, thank you for the gift of god. At the same time, also want to take a holiday to strengthen the harmony between whites and indians. In late November 1621 Thursday, 90 Indians have a joyous gathering the Pilgrims and Massa Soder, celebrated the first Thanksgiving USA history. Male pilgrims go out hunting, capture Turkey, women in the home with corn, pumpkin, sweet potato and fruit to make delicious food. Thus, whites and Indians around the bonfire, chat while eating, but now singing, now dancing, the celebration lasted three days.

篇16:小学三年级期末考试英语作文MyFavoriteSeason

全文共 1966 字

There are four seasons in a year.My favorite season is summer .Because when the summer is coming .I can change the beautiful skirt and I can go swimming .I like the swimming pool very much.In summer ,all things are bright.I can go to a lot of places that I like.In summer holiday,I also can spend my holiday with my parents and we can go to the Forbidden City.How interesting !

The four seasons accompany us and make our lives interesting.Summer is when everyone has fun under the warm sun,autumn is the time of harvesting,and winter’s white snowflakes decorate the bare earth and trees.But it is spring’s vitality that fascinates me the most.

I remember when I was a small child,my favorite season was winter.But one thing made me change my mind.

I loved playing in the garden and climbing trees when I was small.But I realized one autumn day that golden leaves had started to fall from my favorite tree,and by winter its branches were already bare.I thought that it had died,and would never turn green again.

When my father knew why I was crying,he told me:“The tree hasn’t left you.It’s just resting.I promise in three months,that tree will be prettier than ever.” I believed what my father said and waited for three months.

Sure enough,when the time came,the tree was greener and taller than ever.Sprouts started to stretch their heads out of the melting snow,and creeks and streams started to run again freely.

From then on,spring has become my favorite time of the year because its vitality brings me happiness.

一年有四个季节。我最喜欢的季节是夏天。因为夏季即将来临。我可以改变这个漂亮的裙子,我可以去游泳。我非常喜欢游泳池。在夏天,一切都是光明的。我可以去很多地方,我喜欢。在暑假,我还可以花我的假期和我的父母和我们可以去故宫。多么有趣!

四季陪我们,使我们的生活有趣。夏天是当每个人都有有趣的温暖的阳光下,秋天是收获的时候,冬天的白色雪花装饰裸土和树木。但这是春天的活力,最让我着迷。

我记得当我还是个小孩,我最喜欢的季节是冬天。但有一件事使我改变了主意。

我喜欢在花园里玩,爬树的时候小。但我意识到秋天的一天,金色的树叶已经开始从我最喜欢的树,和冬天的树枝已经光秃秃的。我以为它已经死了,不会再变绿了。

当我父亲知道我为什么哭,他告诉我:“这棵树就没离开过你。只是休息。我保证在三个月内,那棵树将会比以前更漂亮了。“我相信我的父亲说,等待三个月。

果然,的时候,这棵树是绿色的,比以往任何时候都高。豆芽开始伸展头上的雪融化,自由和小溪,小溪又开始运行。

从那以后,每年的春天已经成为我最喜欢的时候,因为它的生命力给我带来了快乐。
