雅思大作文提分素材-科技类3: 小孩每天用电脑的坏处

Setting in front of a screen for too long can be damaging to both the eyes and the physical posture of a young child，regardless of what they are using the computer for.(让步状语从句)

The type of computer activities that attract children are often electronic games that tend to be very intense and rather violent. (定语从句)The player is usually the "hero" of the game and too much exposure can encourage children to be self-centred and insensitive to others.

Even when children use a computer for other purposes，such as getting information or emailing friends，it is no substitute for human interaction. Spending time with other children and sharing non-virtual experiences is an important part of a child's development that cannot be provided by a computer.
