I'd give my life for future generations of Tibetans.

Please don't say that Buddhist Tibetan clothes are dirty or not washed, because their hearts, more than anything, are clean! They clean the soul and have dirty clothes, but some have clean clothes and dirty minds!
　　
But for the national policy provides for the development of tourism in Tibet. I really do not appreciate those who have no faith or people of bad faith, to enter this territory.


Please don't say Tibetan people are stupid. In fact we are the smartest thing, try to leave something for children, and do not advocate "run out of" the idea! (I don't understand what is meant here)
Please do not ask what is our last name (I don't understand this phrase either). We believe the Buddha!
Please do not say that Tibetans do not have self-reliance, because we rely on brother provinces and municipalities such as ~~, because the first time to break the isolation of our situation, not our own!

Please do not say that in fact, Tibetans are subject to you. Please understand that we have a unique beliefs, and do not want anything to pose a threat to anything on our faith! Please don't say Tibetan and Putonghua is not good or something. And even that was only our second language in Putonghua! (Do you mean "And Putonghua was only our second language!") 
　　
Also do not forget that after we fell into this room that the Tibetan language is the first language (don't understand what you mean by "room")! Please don't bring your so-called gentlemanliness, civilization, science, fashion, and "well-off" values to Tibetan areas, because Tibetans know how to pray for everything!
　　
Instead of for yourself! (Do you mean that they do not know how to pray for themselves?) 
　　
Please do not apologize because some Tibetan stares at you with a look, or calls you a word you don't understand, apologize. It's just that they are at least able to alert (This word is confusing here. I don't know what word you were looking for)! Please do not present our beliefs as superstition, because saying "you don't understand is that fan, I know is (maybe you mean "Whatever I believe that you don't understand, this is called superstition"), this is called superstition! "If possible, I'd give my life for future generations of Tibetans.

Hi, I really like this. I could really feel your emotion and it moved me to compassion towards the Tibetan people. Unfortuately, there were a lot of phrases that I could not understand the meaning of. I didn't want to put words in your mouth, so I left those phrases as they were and added a note in parentheses.

These links were really helpful! Thanks a lot!

teachers' day host words

Ladies and gentlemen, good afternoon.
There comes the Twenty-seventh Teachers’ Day is here. Dear teachers, on this particular day, there is too much we would like to say to you. We always thank you! You are so hard (I don't know what you mean by "hard". Do you mean that the teachers were strict?)!
You are the first breeze in the spring; you are the first nectar in the summer; you are the first sunshine in the autumn; you are the first snow in the winter.
You are the candle; burn yourself and light the others. You are our second parents and so kind to us.
We will never forget your words. You taught us so much knowledge (you could say "you taught us so much" and leave out "knowledge", or you could say "you gave us so much knowledge". It is usually not correct to say that someone "taught" you "knowledge".) and taught us how to be good people.
There aren’t any words that can express our thankfulness.
So in your festival, we wish you happiness and all wishes come true (you might say, "and we hope that all your wishes come true" or instead, you might say "we wish you happiness and all the best").
My friends, thank you for your participation. Although the singing and dancing are almost over, but we will respect and love you forever. Let’s clap our hands to celebrate teachers’ day once again!
Ladies and gentlemen, it’s time to say goodbye!
Thank you for coming! I wish you health and happiness!

Should children be taught to compete or to cooperate?

"Some people think that a sense of competition in children should be encouraged. Others believe that children who are taught to cooperate rather than compete become more useful adults.
Discuss both these views and give your own opinion."

..........

One of the problems which raises concerns among parents as well as educationalists these days is the question of how best to teach children in the best way. Various statements have been made, and one claim says that children should be taught to compete with each other to encourage them to make every effort to study better. This proves to be a piece of reasonable advice.

The people who advocate the view mentioned earlier can justify their belief, and the main argument is that only with competitions can children try their best to study hard to catch up with their friends in school, due to the fact that these children often have a tendency to feel frustrated when they get lower scores than others. One more plausible explanation is that they will not be anxious or less confident when they have to face the big competitions in the future because they will have been familiar with them since they were in school.

There are, just the same, many who believe that in order to make children become the useful adults in the future, they should be taught to cooperate rather than compete. And they can give the convincing arguments somehow (this should be a seperate sentence. Perhaps you mean, "They also give convincing arguments."), their strongest point is that these children will tend not to ignore their friends when they are in the midst of difficulties, and furthermore will try to help them solve those problems. Or to put it another way, they will not leave their partners back in the competition. Another view worth taking into account is that the children who work in supportive a way, for definite (This phrase isn't nesessary, but if you wanted to keep it, I think you mean either "definitely" or "for sure"), usually have many good friends, and support each other to deal with any troubles and problems as well in their lives.

All things considered, the answer to the question of whether children should be taught to compete or cooperate depends on children 's (do you mean child's character or children's characters?) character. I personally think that children should be led to be cooperating people to contribute more to the society.

Nice paper! My main comment is that you use many words where fewer could be more effective. For instance, the phrase "as often as not" could be replaced with "usually". 

I show my sympathy for Ma Jiajue

I want to tell you a joke. 9 years ago, in China, a university student named Ma Jiajue killed four roommates. That's (maybe you mean "this year"? I can't tell) year, Every graduates will say to their roommates,"I appreciate my roommate not kill me or thanks to the roommate not kill of grace (I am not quite sure what you mean here, but it is not a sentence.)" This is a true story.
