【答案】Dear Jack，
Learning that you want to know how to chat safely online，I'm writing to offer you some advice.
First of all，it's best to protect your privacy and prevent identity theft，which means you shouldn't give out your address and phone number.Additionally，don't click on unfamiliar links to keep yourself away from potential dangers.What's more，never meet online friends alone.If you have to meet him or her，go with your parents or classmates.
I do hope my advice will be of help to you.
