英语你很安全怎么说

To say that someone is "very safe" in English, you can say:
"He/she is very safe."
"He/she is very secure."
"He/she is very protected."
"He/she is very guarded."
"He/she is very shielded."
You could also use adjectives like "risk-free" or "harmless" to convey the idea that someone is safe. For example:
"He/she is completely risk-free."
"He/she is completely harmless."
I hope this helps! Let me know if you have any other questions.
