How to start a composition about science and technology?

Time flies. Farms have become future technology, high-rise buildings have become towering technology companies, and practitioners have put on the clothes of princes. Poor families have also become high-tech homes. The poor days of the past are gone forever. Although times have changed, people are old and strong, just like their parents. They are old and we have grown up. In the future, my brother and I will work together to create a warm family for our parents. I became the chairman of a company and my brother became a scientist. I vowed to benefit the people and help those families who are still out of poverty. His spirit made everyone cry.

On a sunny and refreshing day, I went to visit an old friend, my sixth-grade classmate, who is the president of a science and technology college and is 45 years old this year. I said to my secretary, "Take care of the company first. I will visit a friend. Goodbye. " After that, I took an amphibious space shuttle submarine yacht to the Institute of Science and Technology.

All channels are normal and the space jump is normal; The hull is normal and reaches the destination: "Institute of Science and Technology! Space exit appears, please leave immediately! Bang! There was a loud noise and I landed. I saw a group of graduate students of science and technology enter the Institute of Technology, and I saw a middle-aged man in a suit and tie standing at the main entrance of the Institute. That's right! That's my classmate Xiao Li. I walked over and he noticed me, too. His eyes told me: old friend! I went over to say hello to him for a while, and then went into the college to have tea and chat in his office. I don't know how long it took him to take me to a classroom. The notes and learning contents on the blackboard were written on it at a glance. He said: "This is the memory blackboard, which can read the teacher's brain and write down in detail what the teacher is going to say today. "However, teachers can also choose to write with our mind chalk and use strong spiritual strength to guide chalk writing. This is an eraser of words. After class, it will ask the teacher whether to erase the learning content and notes. The teacher only needs to answer: yes or no, I followed him around the whole school and introduced me to many high technologies. Time to go. I said to him, "I have to go. My company has some things to deal with. We will come to see you next time. Goodbye! He answered me, "Goodbye!" In this way, I returned to the company and continued my busy work.

But at this moment, my heart keeps saying to myself: I must turn this world into a high-tech world! Benefit all mankind!
