Some recent developments in computer industry make scientists predict that the gap between human beings and the machine will be closed by the year 20000.
To understand the significance of this prediction, let us compare the human brain with existing computers. The brain consumes electrical energy at the rate of 25 watts and occupies volume of one tenth of a cubic foot. The brain houses between 10 billion and 100 billion items of information. Every brain cell is directly connected to many other cells. As a result, the cells in which information is stored can communicate with thousands of other cells. In contrast, the computer consumes 1,000,000 watts of electrical power and occupies hundreds of cubic feet of space. The computer memory is like a cell of pigeonholes, with no thinking capacity and no connections elsewhere.
In a word, the electronic brains can hopelessly succeed in comparison with the human brains.英语作文 篇2

it is believed in common that beauty eists everywhere on the campus as long as you have an eye for it. some people hold that natural scenes, especially at dawn, are the most beautiful on the campus while others believe that it is in the afternoon when the playgrounds are flooded with students taking part in sports.in my opinion, the best scene on the campus is during the rush hour when thousands of students rush towards the canteen.
at precisely the same time as the bell rings, some students dash from the chairs, rushing to the canteen. they set the prelude to the most attractive scene of the whole day.
within a few minutes, all the classrooms become empty and everyone starts their journey for lunch, on foot or by bike. it gives people the impression that lunch is the most important thing in the world. most of the students move at the same speed,with the eception of several ecellent cyclists. they shuttle smoothly in the crowds just like fish swimming freely in the sea.
on the way to the canteen, everyone looks anious. but once inside, a look of pride and triumph takes over. sometimes,it bubbles up in my mind that the rush hour hustle and bustle is the epitome of the intense competition in real life. if you want to realize your epectations, you must be armed with skills and knowledge, use time and resources efficiently and the most importantly, have a healthy body.英语作文 篇6
One Sunday afternoon, Tom and his father decided to go fishing. They got to a river nearby and began to fish at once. They were so lucky that they caught a big fish very soon. How happy they were! While they were beginning to go home, Tom saw a sign. It said “No fishing”. So he poured the fish back into the river. His father was so angry that he asked Tom what he did that for. Tom pointed to the sign and said, “but it said ‘No Fishing’”, we mustn’t break the law.” “Er, you are right. Now, let’s go home.”
What a good boy Tom is! We should learn from him. He does very well in conserving the nature, I think.英语作文 篇7
