The Effects of Technology on Learning
The technological advances of the last few years have been amazing. Never before have students had such a wide variety of resources to help them in their studies. Those who can take advantage of these resources have the opportunity to learn about more subjects and to acquire more in-depth knowledge. In my opinion, students can indeed learn more and learn more quickly with the help of modern technology.
The piece of technology most important as a learning tool must be the computer. Paired with the Internet, it allows students to research topics more quickly and thoroughly and to write up their findings more rapidly as well. Furthermore, advances in many fields are being made so fast these days that it is impossible four textbooks to keep up. Technology allows students to keep abreast of the latest developments. Also, it cannot be denied that many students enjoy using such resources in their studies. Because of this, they are more likely to pursue subjects in greater depth.
For all these reasons, I believe that technology is of great benefit to today’s students. Of course, it is still possible to learn without the aid of such devices, but I believe that those students who are fortunate enough to have access to technological resources should take every advantage of them.

一篇关于 科学实验的 英语小作文 急需

In ancient times, many people believed the earth was a flat disc. Well over 2,000 years ago; the ancient Greek philosophers were able to put forward two good arguments proving that it was not. Direct observations of heavenly bodies were the basis of both these arguments. First, the Greeks knew that during eclipses of the moon the earth was between the sun and the moon, and they saw that during these eclipses, the earth's shadow on the moon was always round, they realized that this could be true only if the earth was spherical, If the earth was a flat disc, then its shadow during eclipses would not be a perfect circle; it would be stretched out into a long ellipse. The second argument was based on what the Greeks saw during their travels. They noticed that the North Star, or Polaris, appeared lower in the sky when they traveled south, in the more northerly regions, the North Star appeared to them to be much higher in the sky. By the way, it was also from this difference in the apparent position of the North Star that the Greeks first calculated the approximate distance around the circumference of the earth, a figure recorded in ancient documents says 400.000 stadium, that's the plural of the world stadium. Today, it's not known exactly what length one stadium represents, but let's say it was about 200 meters, the length of many athletic stadiums. This would make the Greeks estimate about twice the figure accepted today, a very good estimate for those writing so long before even the first telescope was invented.
