every one has his own dream.when i was a little kid ,my dream was even to have a candy shop of my own .but now ,when i am 16 years old ,standing here ,my dreams have already changed a lot.

i have got quite different experience from other girls.while they were playing toys at home,while they were dreaming to be the princesses in the story .i was running in the hard rain,jumping in the heavy snow,pitching in the strong wind.nothing could stop me ,because of a wonderful call from my heart -- to be an athlete.yeah ,of course ,i'm an athlete,i'm so proud of that all the time .

when i was 10 years old ,i became a shot-put athlete.the training was really hard ,i couldn't bear the heavy shot in my hands .but i always believe that "god only help those who help themselves".during those hard days,i find i was growing more quickly than others of the same age.to be an athlete is my most correct choice.but,i quit my team after entering high school because of a silly excuse.i really didn't want to stop my sports career anyway.

today i say to you my friends that even though i must face the difficulties of yesterday ,today and tomorrow .i still have a dream .it is a dream deeply rooted in my soul.

i have a dream that one day ,i can run,jump and pitch just like i used to be.

i have a dream that one day , i can go back to my dream sports and join the national team.

i have a dream that one day ,i can stand on the highest place at the olympic games.with all the cameras pointing at me.i will tell everyone that i'm so proud to be a chinese athlete!

this is my hope .this is the faith that i continue my steps with!!!

with this faith ,i will live though the strong wind and heavy rain ,never give up !

so let victory ring from my heart,from all of you.when we allow victory to ring .i must be the one!

in my imagination,i'm a bird ,a magical bird.i carry my dreams all with me by my big wings. i fly though the mountains ,though the forests ,over the sea,to the sun ,the warmest place in the aerospace!

when a variety of problems plague the information systems, the critical importance of information security becomes the focus of people's concern. it does deserve the unprecedented emphasis. it is widely accepted that information security, to some extent, outweighs other spheres in the field of information. so the related authorities, enterprises, institutions and organizations place the high priority on it.

information security concerns a range of problems- information interception, loss, damage etc. business and military information leakage will have an devastating impact. for the information owners and monitors, they must drive their efforts to enhance the security protection and maintenance. for example, a strict control over the access to the secret data shouldn't be absent. the network and software provider should take a set of tailored protection measures targeting different computer crimes. the security issues should be also considered at the legislative level, so we are clamoring for a law designed to clamp down on various cyber crimes.

i have been in university for about one year. during my stay here, i came to realize that university life is like drinking coke. we experience all tastes of life here, sour, sweet, bitter and hot.

i am from province, which is far away from here. i often miss my mum, friends, and relatives in my hometown. however, i can't see them very often. so loneliness always keeps me company. i am sad that i can't be there with them.

lucky for me, life in university is rich and colorful. with more free time,we can do many more things besides study, such as joining societies clubs, and taking part-time jobs. such activities not only make our life more colorful, but also help us improve all kinds of skills. the university is a society miniature, what we learn here will benefit our future life.

our path in life will not always be smooth. setbacks can't be avoided. failing an important exam, break up with boy or girl friend, or refused by a promising company, such setbacks are likely to get us down. sometimes we fell so frustrated that we even burst into tears.

drinkin coke is wonderful, despite the undesirble consequent hiccups. it's bitter, sour and peppery, but also sweet. and you'll even feel excited after gulping down a glass. a college experience is part of growing up. we cry, smile, fall in love, get hurt, leave, learn and then we become a better person.

university life is like drinking coke. i'm experiencing it. and i know, i enjoy it!

what is my favorite invention?

we knew there had been many inventions at the last century, for example, electric light bulb, telephone, phonograph, mimeograph machine, automobile, airplane, atomic weapon, computer and so on. what is my favorite invention?

personally, my favorite invention should be computer. in the old days, many scientists took much time to calculate and deal with research data, so the effective time in doing research was relatively shortened. for millions of times of calculating per second by computer, the researchers may have enough time to study more important issues. the processing of experiment results became very simple and easy. aren’t those all evidences that the computer is one of the greatest inventions in the last century, are those?
