Online Shopping Safety
When it comes to shopping online safety, as an experienced netizen, whose net age is more that 10 years, I’m sure that I know one thing or two. Here are some tips for you.
First, it is highly recommended that you use the shopping websites you are familiar with. Download familiar app or software like taobao. In addition, when registering a shopping website, you might as well use a strong password and keep it well. Furthermore, never use public computers to shop online, or your privacy will be recorded in the computers. Last, great importance should be attached to installing a firewall to watch over your information. A firewall is a kind of software to protect your using Internet.
Do you have any good tips about shopping online safely？Your ideas are welcomed below!
Today, I want to blog about shopping online safety, which has drawn wide attention nowadays. With the development of the Internet, many people are used to shopping online.
Shopping online embraces many advantages. Just by a click of the mouse, you can buy whatever you’re interested in without going outdoors. When shopping online, you can choose from varieties of goods, whose prices are generally lower.
Nevertheless, some people hold the belief that its drawbacks overweigh merits. Initially, it’s very easy for you to buy goods different from the pictures you see on the Internet. In addition, shopping online may cause people to buy goods that are not urgently needed.
From my standpoint, the Internet is a double-edged sword. Only if we use the Internet more normatively，can we shop online more safely. What’s your opinion about shopping online Post your comments below!

Sample writing 2:
How to stay safe in the online chat room
Today I thought I'd blog about a question that has been asked many times--- how do you stay safe online and avoid bad experiences in the online chat room I'm not an expert, but many years as a blogger have taught me a thing or two.
First of all, there's the golden rule of the Internet: keep out of what makes you uneasy. Don't post comments or click on anything. Besides, protect your privacy. Don't give out too much private information like your address, phone numbers, the ID numbers, etc. The more cautious you are online, the less likely you are to become the easy target of cyberbully. Last but not least, be polite. If you are polite to others on the Internet, you won't be attacked in normal situation. Finally, don't believe in others easily and never meet someone you met online alone. It is very dangerous.
Have you had any bad experiences online, or do you have some good advice for staying safe Post your comments below!
