你的美国笔友Tom来信和你讨论个人信息保护问题，让你就如何保护个人信息给他一些建议。请你以李华的名义重点从以下两个方面谈谈自己的看法：
1．给予足够重视； 2．学会如何保护。 注意：1.词数100左右；

We are living in the Information Age.
Yours， Li Hua 参考范文 Dear Tom， We are living in the Information Age.The protection of personal information is becoming more and more important.Here I’d like to give you some advice on this.
First of all，you should pay enough attention to the protection of your personal information.Remember: once you’ve shared something，you will lose control of it and some people may share upsetting things about you without you knowing it.
Secondly，you must know how to protect your personal information.For example，never provide your personal information for any strangers or people you know online.If necessary，you’d better confirm it is for legal use before letting it out.If you receive an official-looking email that asks you to send your financial details，you should never reply as you could become a victim of identity fraud.
