Technology is everywhere, affecting almost every aspect of our life. So it is no doubt that technology had become an important part of our daily life. But it is actually a double-edged sword.

Taking the Internet for example. For one thing, the Internet makes our study more convenient, what definitely improves our learning efficiency. For another, it provides us with an excellent opportunity to broaden our horizon. However, it can sometimes do harm to our health, especially our eyes, unless we overuse it.

As a result, when it comes to technology, we should look it objectively and reasonable. We should make the full use of the Internet and meanwhile, protect yourselves from its potential harm.
