在中国,凡逢春节和其他的喜庆日子,人们总要燃放爆竹来表示庆贺.燃放爆竹可以说是中国民间一个十分重要的风俗习惯.

爆竹也叫"炮竹","爆仗","炮仗",平常人们更习惯叫"鞭炮",有大约2000多年的历史了.最早的爆竹叫"庭燎".是用竹竿一类的东西做成火炬,燃烧时发出噼噼啪啪的爆裂声,也叫"爆竿.

燃放爆竹风俗最早起因于驱鬼除邪,祈求一年的吉祥顺利.传说,有个叫做"山臊"的四角怪兽和恶鬼平常藏在深山,每隔365天便出来伤害人畜.这些无恶不做的坏东西害怕爆炸的声音和亮光.于是,每到岁末年首,人们就争着燃放鞭炮,用来驱赶"山臊"和恶鬼.

中国的唐代发明火药以后,人们便把火药放进竹筒,点燃后发出巨大的声音,这种爆竹叫做"爆竹筒".到了宋代,爆竹的制作方法改为把火药装进用纸卷成的筒里,名字也叫爆竹了.后来人们开始把许多小的炮仗用药线连接起来,成为"一发连百余响不绝"的鞭炮.讲究的鞭炮用红颜色的纸制作,鞭炮爆炸后,红屑满地,人称"满地红",表示吉利.随着发展,鞭炮的品种和色彩也由原来的单调发展得丰富多彩,有小鞭炮,电光雷,母子雷,射天炮,百头,千头鞭,甚至还有几万头长的鞭炮.

现在,随着人们环保意识的加强,燃放鞭炮的习俗在中国很多大城市中受到禁止.但是,聪明的中国人依然想出了其他热闹的庆祝节日的办法.

dear eric,

My hometown is beautiful place It stands near a wide river at the foot of low green hills. It has many tall buildings and wide streets. There are trees and flowers everywhere.

But it has not always been like that. In the old days, it was a sad dirty little town. Landlords and merchants lived in the few good houses. For the working people there were only dark, unhealthy rooms in old buildings and huts in narrow muddy streets. Nearly everyone was poor and many had no work.

Everything has changed since liberation. The people, led by the Party, have got rid of the mud and dirt. They have put up schools, theaters, shops and flats. They have an assembly hall and a hospital. Along the river they have built offices, hotels and parks. A lot of factories have sprung up. On the river, streamers and boats come and go busily, day and night. They carry the products of our industries to all parts of the country.

I love my hometown, and I love its people. They also have changed. Healthy and happy, they are going all out to build socialism.

My name isxx.  I am graduate from xxx seniorhigh school and major in xx.  There are xx people in my family.  My father works in a computer company.  And my mother is a housewife.  I am the youngest one in my family.

In my spare time, I like to read novels.  I think reading could enlargemy knowledge.  As for novels, I could imagine whatever I like such as a well-known scientist or a kung-fu master.  In addition to reading, I also like to play PC games.  A lot of grownups think playing PC games hinders the students from learning.  But I think PC games could motivate me to learn something such as English or Japanese. My favorite course is English because I think it is interesting to say one thing via different sounds.  I wish my English could be improved in the next four years and be able to speak fluent English in the future.

Both team has 11 people. We have 90 minutes in a match. We can pass the ball with our feet. You must run and run because maybe the others will kick the football.

In America we call it soccer, in England we call it football. That’s why we sometimes call it “soccer” or “football”.

If we have a football match, we must wear special clothes.

I think football is a good game to play, don’t you?
