Our life has become easier and more colorful because of mobile phones and the Internet. However, a number of worrying problems have come along with them.
Many car accidents are caused by mobile phones. Some drivers use mobile phones to get on the Internet while driving. Looking at their mobile phones and not at the road, these drivers have become a danger to us all.
Many of the dangers of the Internet are well known. Children who visit websites without their parents‘' permission sometimes talk to elder people they don't know and put themselves in great danger. People with blogs sometimes post information of people they don't know on their websites without permission. Some people even use the Internet to get personal information that we do not want them to have.
Mobile phone and the Internet safety tips：
Use a ‘hands-free' phone if you need to use a mobile phone when you drive.
In difficult driving situations such as in rain or snow, do not use your phone at all.
Do not make very important phone calls while driving. They take your attention (注意力) off the road.
Tell your children not to talk with anyone they do not know on the Internet.
In an embarrassing situation (尴尬场合), be careful with people around you.
Don't give out any personal information on the Internet.
