Ngày nay, công nghệ thông tin ngày càng phát triển mạnh mẽ. Nào là :  tivi, đoạn thoại, máy tính, ... và một số thiết bị công nghệ khác. Tất cả đều như những sinh vật sống, tiên tiến theo từng ngày. Công nghệ thông tin phát triển mạnh mẽ đến mức những đồ vật ngày xưa hay dùng đang dần chìm trong quên lãng. Ngày nay, các thiết bị tiên tiến được rất nhiều người ưu chuộng và sử dụng nó. Nhất là giới trẻ và các bạn học sinh hiện nay, thường quá lạm dụng công nghệ vào việc học, việc chơi, ... gây ra tác hại là bị nghiện. Ngoài ra, trên các thiết bị này, thường xuất hiện rất nhiều trang web chia sẻ thông tin. Nhưng có nhiều người dùng nó một cách sai trái, luôn truyền những thứ tiêu cực cho mọi người. Ôi ! Thật sai lầm. Mọi người hãy nhớ rằng :"Những trang web đó chỉ dùng để giao lưu, tìm tòi những thông tin bổ ích cho mình và là nơi giải trí sau giờ học căng thẳng. Đừng sử dụng nó sai với công dụng ban đầu."
