if grow up, i really became a scientist. i'll watch carefully what on earth have ecological changes, etc., the place with bad, invention related equipment.

i found that the earth environment is becoming worse. i want to invent a kind of electronic bird. it will suck erosion of heaven in the sky fly dust, make the sky more blue. when birds hopping on the ground, it will suck the ground of garbage, let the air becomes more pure and fresh, as you all know, birds can't swim, but electronic birds can swim, it can put the polluted river has become clean and clear.

i also found that the present shortage of resources. i invented a kind of fast forward. it put the resources of rolled to hundreds of years, several thousand years, tens of thousands of years, hundreds of millions of years. but in this period of time, man is not old, resources can be increased.

if the invention is not the good earth, i will invent a kind of speed of the spacecraft, the spacecraft is fully automatic. it can automatically search for habitable planets in space and take the human to the planet. the speed of the spacecraft surface is very small. there is only one double bed so big, but can take ten thousand people at a time. because of the speed of light, the spacecraft compact so it won't hit the rocks. planet. and it is very fast, as long as 0.0003 seconds per km back and forth. if really can not find a suitable planet. the speed of light, the spacecraft will be turned into a is bigger than the earth planet for people to live, this planet similar to earth. but in fact it has many functions, the inside of the house is the earthquake of flood control. cutting trees sprout up immediately. always very clear fresh air, the air is always blue... .

these are just my dream. but i hope it can become a reality.

每个人都有梦想，想当警察，想当老师，想当小说家……我也有梦想，我的梦想是当科学家。

如果长大，我真的当上了科学家。我会仔细观察地球上有什么生态变化等，不好的地方，发明相关的设备机器。

我发现地球的环境越来越差。我想发明一种电子小鸟。它在天上飞时会吸蚀天上的灰尘，让天上变得更加湛蓝。当小鸟在地上蹦跳时，它会吸走地上的垃圾，让空气变得更加清新，大家都知道，小鸟是不会游泳的，可是电子小鸟却会游泳，它能把被污染的河流变得干净清澈。

我还发现，现在的资源短缺。我发明一种时光飞转器。它的产生把资源的地方飞转到几百年，几千年，几万年，几亿年后。可在这段时间内，人是不会老去的，资源却可以增加。

如果这些发明还不能把地球变好，我就发明一种光速飞船，这个飞船是全自动的。它可以自动查找太空中适合人类居住的星球并带人类去那个星球。这个光速飞船表面很小巧。只有一个双人床那么大，可却能一次带一万人。正因为光速飞船小巧所以它不会撞到陨石。星球。而且它速度很快，来回只要每千米0.0003秒。如果实在找不到适合的星球。光速飞船就会变身成一个比地球还大的星球给人们住，这个星球里面跟地球差不多。可其实它有许多功能，里面的房子是抗震防洪的。树砍掉立刻会长出来。空气永远很清鲜，空气永远湛蓝……。

这些现在还只是我的梦想。但我希望它能变成现实。

the origin of basketball

the challenge that inspired the invention of basketball came from dr. luther halsey gulick, jr., the superintendent of physical education at the international ymca training school. during the summer session of 1891, gulick introduced a new course in the psychology of play, and naismith was one of his students. in class discussions, gulick brought up an issue that was weighing on his mind: the need for new indoor game "that would be interesting, easy to learn, and easy to play in the winter and by artificial light."

though the class didn't follow up on gulick's challenge to invent such a game, naismith found himself revisiting the issue a few months later when the physical education faculty met to discuss what was becoming a persistent problem. with the end of the fall sports season, the school once again confronted the distaste many students felt for the gymnasium work that was mandatory during the winter months. one class was particularly incorrigible, and two instructors had already tried and failed to devise activities that would interest them.

i dream of being a doctor.

my mother is a doctor. she always has to work extra hours and comes home late and tired. she has to go to the hospital immediately any time she is needed, no matter how late it is at night. when i was very little and still in primary school, i once asked her why she chose such a boring and hard job. she answered with a smile, yes i am sometimes very tired but seeing my patients getting better and better makes me happy from the bottom of my heart.

as i grow up, i gradually come to understand her words and realize doctors are noble. i made up my mind to be a doctor when i was in junior school and this has never changed since then.

i really hope to see a world where there is no cancer, no aids, no fatal disease, no one suffering from illness. but this is only a fantasy. what about the reality? there are still many many people who are faced with disastrous disease and suffering from constant pain. there are still many many people living in miserable condition and live miserably. there are still many many people dying of cancer and leaving the beautiful world reluctantly. all those things make me feel sad because i think everyone has the right to live . i want to help the sick and reduce their pain as much as i can. i want to bring a healthy body to the patients and save their lives as many as i can. i want to see people cured ,living happily with their families and friends after my treatment. so i want to be a doctor ,an angel in white.

when i become a doctor, i will cherish each life regardless of the races, sexes, ages, positions and occupations. i will do every bit to cure the incurable.

i already have a dream in my heart,so i have to make every effort to realize it.as a high school student now,i will seize every chance to study hard,arm myself with knowledge, prepare myself for the future and strive for my dreams. i will be determined, face the reality bravely and not surrender to any problems i meet.

issquo;s like gothe says,the important thing in life is to have a great aim and be determined to attain it.being a doctor is my dream. i think it is simple but meanful.

the world changed when james watt invented the first steam engine, when is放飞梦想的英语即兴演讲稿c newton discovered the universal gravitation after hit by an apple, when karl marx wrote the communist manifesto, when chairman mao solemnly declared the establishment of the people's republic of china on the tian'anmen rostrum, when martin luther king cried out i have a dream. the world was changed by something called dream, which is invisible, untouchable but strong enough.

i can assure that every child have written a composition titled my dream. they have already written down their longing for the future. some of them want to become scientists; some of them hope to become teachers or doctors. maybe they didnsquo;t know how many difficulties they will face before their dream come true. but the dreams are like small seeds planted in their hearts; like the beacon in the sea that lead them to their destinations.

dream is the fountain of strength. dream is the support of faith. dream is the polaris. dream reminds us to move forward, to struggle, to strive all the time. one of my friends told me that dream will never discard anyone! yes, maybe one day everything is gone but dreams is still there with you, eternally.

dream changed us, and therefore we changed the world. it is dream that refreshes the world every day. it is also dream that makes the world improve day by day. we dare to dream. we can also achieve our dreams and change the world.

i cansquo;t imagine the world without dreams. how about you?
