1. I think the most important technology in current age is smart phones. Because we can do anything with it such as map, musics, games, studying, and etc, so most of people in the world have it.

There are good effects on technology. First, we can get lots of information for free, so we can do assignments or homeworks easily. Second, it makes our lives more convenient. We can do anything with smart phones and computers at home. Lastly, we are connected by Internet. We can communicate with any people easily.
There are also bad effects on technology. First of all, we can get lots of information for free, but it can be false. And we can be distracted by the Internet. If we use computers or smart phones in class, we could be distracted. Lastly, children are not protected. We can connect to any others easily on the Internet, so children can be connected with others who they don’t know.
