Hello, teachers and classmates The topic of my next speech is "Dreams create the future".
Bell, a professor at Boston University in the United States, suddenly had an idea in the process of studying multiplex telegrams: Can people's voices be transmitted far away with current, so that people far away in Qianshan can be close at hand? With this dream, Bell began the journey of researching the telephone. Many things happen. 1On March 7th, 876, Bell became the patentee of telephone invention. It is because of Bell's telephone that the way of human communication has been refreshed.
Before 1968, a network construction dream of the US Defense Advanced Planning Agency gave birth to the world-famous "ARPANET". From 1969, when the first host of ARPANET was put into operation, to the end of 1989, ARPANET had been running for 20 years. In these 20 years, the network technology has been continuously improved, and the team of network users is also expanding. Especially 1987, the number of users has soared. Since 1988, the number of netizens has doubled every year. 1995, the backbone network of the Internet developed from 6 nodes with a transmission speed of 56,000 baud rate to 2 1 node, and the data transmission speed also increased to 45 megabits baud rate. At this time, there are about 29,000 websites accessing the Internet in the United States and more than 50,000 websites accessing the Internet all over the world. Today, there are more than 1 100 million websites connected to the Internet all over the world. A dream has made the highway of the world information network.
Thousands of years ago, mankind had a dream of flying. 196 1 the birth of the first manned spaceship and its successful entry into space made human's fantasy of the space world come true, and even increased human's yearning for space.
The emergence of "freezing people" technology has fulfilled the dreams of people who are entangled in terminal diseases and eager to survive. Perhaps there is no dream that terminally ill patients yearn for survival, and scientists will not think that people can be "frozen". In the future, when the medical level is improved, patients will be "thawed" and their illness will be cured.
Humans still have many dreams that may come true in the near future.
For example, one day, AIDS and cancer are no longer the "first killers" of mankind. Humans will no longer talk about it and be afraid of it, but will be as relaxed as treating diseases such as colds.
For example, one day, human beings invented high-tech products to predict earthquakes, so as to minimize the losses caused by natural disasters such as earthquakes.
Think about it, how many dreams of ancient people have come true now. Electric light, telephone, TV, computer, car, plane, which is not born to respond to dreams. With a dream, there is a pursuit. With pursuit, it is possible. It may become a reality. Anything is possible. Dreams create the future.
