21st century is the century of technology. Nowadays, technology is everywhere around us. The development of technology has a significant affact toward the society. Several technologies that we usually use are the internet, computer, and cellphone. These new technologies make our life much easier and better. First, the development of computer changes our life. Decades ago, people needed to do lots of complex calculation on hand because they did not have computer, and more obvious, they did not have the software for calculation. As the result of that, people spent hours on the equations that a computer can solve in just a minute. Since the development of computer, people are able to use some kind of software to compute lots of complex functions and mathematical calculation. Computer becomes the most helpful equipment for the sciencists because they can use their time more efficiently. Also, internet is another useful tool for us today. The development of internet brings a great impact toward the society. Instead of going to library and fliping all the books to figure out some information, we can just simply use a mouse and click on the website to do research. The internet leads us to a place where we can find unlimited information and resources. It makes our life much easier and better. The last technology is cellphone. Nowadays, many people have a cellphone. But it just appears on the market for about 10 years. It is very convenience to the users because we can talk to anyone we want with a phone as small as a wallet. Also, we can communicate with others by making a phone call instead of sending letters. It is very fast and useful way to communicate. In conclusion, I believe the development of technology brings significant impact to our life. It is very helpful to us and I believe technology will keep improving in future. I HOPE IT HELPS!加20分

Albert Einstein is a true science hero, not only because of his genius and physics theories, but also because of his philosophy and compassion for the universe and its creatures.
爱因斯坦是科学英雄,不仅表现在物理学上,更在於他对宇宙万物的同情和哲理上。。

As is shown in the picture, in front of a computer happily sits a teenager, attempting to work on his homework with no effort, only by searching the Internet for the answer. It does show us that our life has been greatly influenced and changed by the Internet.On the one hand, with the touch of a button or the click of a mouse, we can acquire what we want from the Internet. On the other hand, as has been shown in the picture, while computers are helping students finish the academic jobs, they are also killing the students’ creative thinking and exploration spirit. One effect of this key board dependence is that the young, nowadays, even can seldom spell correctly, let alone the improvement of their learning capacity and skills.In my view, while enjoying the convenience of the Internet, we should learn how to handle the problems it has caused. Only in this way will the benefits of the Internet outweigh its disadvantages.
