12 May 2006

Dear Sir,

I am a December 2003 graduate from the University of San Francisco (USF) with a bachelors degree in International Business. As part of my career planning, I am very interested in supplementing my international business education with a basic knowledge of the Chinese language. This I hope will help me enter into business commerce with business organizations partnering with Chinas economic development.

I already have information from BLCU and hope to study there for at least one full year starting with this summers program continuing through the fall and spring semester 2006. Can your office advise me if such scholarships might be available to me?

I have been studying Chinese for one year now. I am not sure what level I belong to. I was told that there will be an HSK test in our university in September. I am planning to attend the test. But I dont know if the result of the test is recognized by your university. If so, can it be a help for me to apply for the scholarship?

I am looking forward to hearing from you soon.

Yours faithfully,

Tom Jolly

可爱的同学们!每一天,我们都在学校的课堂中学习、成长。而我今天就来写一写我的课堂--快乐的课堂。

星期二的上午的第四节课,是一节音乐课,在这节音乐课上,我们不仅唱了《校歌》,还学会了谱一首优美动听的歌曲,还做了一个小游戏。

一上课,班里就响起了阵阵动听、悦耳校歌声,歌声好听极了,简直可以和百灵鸟的歌声相媲美了。

首先,老师先教给我们一首歌,她一句一句的教,然后让我们来唱,最后我们都学会了,男生和女生还要比赛呢!男生的歌声雄壮、有力;女生的歌声则是优美、动人,这两种声音结合在一起:让伤心的人听了,马上开心起来;让愤怒的人听了,又马上平静了下来;让开心的人听了,不自觉的就跟着美妙的音乐唱了起来。

后来,老师又教我们谱一些小曲子,那些曲子虽然短,但是都很好听,让人听了感到舒服极了!

最后,在音乐的伴奏下,老师让两个会跳拉丁舞的同学在老师的伴奏下,翩翩起舞。舞蹈跳完后,全班同学给予他们热烈的掌声,那两个同学也开心极了!

“春眠不觉晓,处处闻啼鸟。……”,下课了,同学们还都沉浸在音乐的海洋里。同学们的嘴里还哼唱着上课学习的歌曲,这其中也包括我。

通过这节音乐课,我不仅学会了一首动听的歌曲,而且懂得了怎样谱一首悦耳、动听的乐谱。

真是个快乐的课堂啊!

篇12:有关电脑的小学英语

With the rapid process of modernization, computer becomes more and more

popular. Nowadays, almost every family has a computer. Because of computers, our

daily life is improving.

Computer has a great effect on our daily life. In the first place, computer

has so many functions. As we have computers, we neednt buy books, radios, TVs

and any other things, because computer can take place of them. Secondly, surfing

on the Internet must be very interesting. Through the Internet, we can do

everything we like. Thirdly, thanks to the Internet, we can get the further

education at any time, so we dont have to get up so early in winter days.

However, a coin has two sides, because its new doesnt mean its always

good. At present, most students spend too much time on computer games. I dont

think its a good phenomenon, because it will do great harm to our eyes as well

as our health if we play computer games all the time.

In my opinion, we should use the computers in the right way. For instance,

we can read the latest news on the internet to know the world better; read the

e-books to enrich our knowledge or download some useful information for our

work. We can also make different friends on the Internet, so that our life will

be colorful. I believe computers will be our best friends if we make good use of

them.

篇20:关于雾霾的研究小论文小学作文

全文共 745 字

+ 加入清单

看看近几天的报纸,我发现,空气污染越来越严重了,杭州的空气质量指数不断的下降,这到底是为什么呢?原来,这都是霾搞的鬼。

到底什么是雾霾呢?它有多大的危害?雾霾天气是怎么形成的呢?我们又能为敢走雾霾天气做出一些力所能及的事情呢?通过资料的收集和自己的了解,我找到了答案。

原来,雾霾是雾和霾的组合词。因为空气质量的恶化,雾霾天气现象出现增多,危害加重。中国不少地区把雾霾天气现象并入雾一起作为灾害性天气预警预报。统称为“雾霾天气”。雾霾的危害可大了!由于雾霾、轻雾、沙尘暴、扬沙、浮尘、烟雾等天气现象,都是因浮游在空中大量极微细的尘粒或烟粒等影响致使能见度很差,开车时,由于能见度差,就可能会引起车祸。霾在吸入人的呼吸道后对人体有害,长期吸入严重者会导致死亡。所以呢,在雾霾天气到来时,我们应该少在户外活动,一定要出去的话,一定要戴上口罩。少开窗,多补充维生素。这些都是预防雾霾的好方法哦!

这样害人的雾霾是怎样形成的呢?一大部分还是我们人类自己造成的。形成的原因有五个:

一、大气空气气压低,空气不流动时主要因素。由于空气的不流动,使空气中的微小颗粒聚集,漂浮在空气中。

二、地面灰尘大,空气湿度低,地面的人和车流使灰尘搅动起来。

三、汽车尾气是主要的污染物排放,近年来城市的汽车越来越多,排放的汽车尾气是雾霾的一个因素。

四、工厂制造出的二次污染。

五、冬季取暖排放的CO2等污染物。

其中,第二三四五条都是我们人类造成的,那我们是不是要减少这些行为,为治理空气污染做出贡献呢?

现在,城市里的汽车太多了,尾气排放造成了空气污染。我们要倡导绿色出行,出门尽量用公共交通工具,最好能骑自行车,这样就能有效的减少空气污染的程度。

祖国是我们的家,我们应该保护她。让我们绿色出行,减少尾气排放。让我们的家园更美丽!
