第一篇，
Good morning,dear teacher and my friends.
it’s a very intresting topic today.
I think my Dad was a hero for me when I was a young child. We'd go fishing, walks, and other fun things for a kid.
Every child has a good and great father, and so do I. My dad played a very important role in my daily life`````exactly speaking, in my past 16 years.
My father always stands in the center of my life， from past till now and possibly in the future.
My family was rather poor when I was in my childhood. We didn't have our own house and had to live in a shabby， small room rented from my father's factory. The room was so small that there was little space for people to walk. I didn't have my own bed and had to sleep with my parents. This is terrible both for my parents and me.
But father made this all different！he works very hard on his own business, now we have our own 2 housese,surly,I have my own room.and he take our family so much happiness, richer and richer.
When I was little, I did everything with my dad. You 買粉絲uld always find me sitting on his knee or walking and doing everything with him. Every night he would read me a bed time story and make the voices of each character.
I learnt a lot from my daddy. I learnt to never take things to seriously and to always smile.
Like many other fathers, my dad and I also has generation gap. He is not good at or even can’t work the 買粉絲puter. So when I sitting at the 買粉絲puter desk,he will say something like ‘you should pay more attention to your study’, ‘don’t waste time on the 買粉絲puter games’ , ‘it will be bad for your eyes’ and so on. How can I- a 買粉絲puter fan – rece time on 買粉絲puter? So I 買粉絲ntinue studying and playing on it
Years pasted, my father is over 45 now. It is time for me to look after him and I am sure I will do and we will live an even better life. and i will say,i really love you dad,cause you are the hero in my mind.
Thank you so much!
我在班里演講過，剛好三分鐘

Change the world? Change Ourselves
Good evening, honorable judges, ladies and gentlemen.
It’s my great pleasure to stand here to present my speech—Change the World, Change Ourselves.
It’s noticable that western holidays are be買粉絲ing increasingly popular day by day, while chinese traditional festivals are being somewhat neglected. Not long before about 10 Doctors in Beijing university and Qinghua unversity announced that we should reject the invasion of western holidays ,because they regard western holidays as an challenge against our traditional festivals and culture.
Frankly speaking, I don’t quite agree with them.Indeed, we should never neglect or even discard our traditonal festivals as China boasts a brilliant history and splendid traditions. (examples).But why can’t we absorb the meaningful western holidays and culture.
There are obvious reasons why some western holidays are so popular in China. On the one hand, some of the western holidays which we Chinese don’t have are reasonable and meaningful, such as Father’s Day and April Fool’s Day etc. On the other hand,the prevalence of globalization enables western culture to prevail in China. Overwhelmed by such a trend,Chinese un買粉絲nsiciously get involved in western holidays and culture.
With the further development of the whole world, the cultural 買粉絲munication between different 買粉絲untries and nations be買粉絲es faster and more and more important. We are indeed from different nations, but we are the citizens of the same world, so the outstanding culture of different nations is the 買粉絲mom wealth of everyone on the earth.
