When talking about life experience we usually use the present perfect form and may combine that with words such as 'before' or 'ever' which will clearly define the time period you mean.
'Before' would mean, 'the time period preceding now,' and 'ever' means 'at any time in your life.'
"Have you ever seen a crocodile?"
人生の中での経験について話すときは、 'before' （以前）や 'ever' （今まで）という言葉を混ぜ、現在完了形を使って表現します。
"Have you ever seen a crocodile?"
クロコダイルを今まで見たことがありますか？
When we are eating new foods, we often say 'try'.
"here try this, it's really good".
"Have you tried out the restaurant down the road yet?"
So when you are asking if someone has tasted this food before, you say 'try'!
新しい食べ物を食べるとき、tryという言葉をよく使います。
"here try this, it's really good".
ほら、これ食べてみて。すごくおいしいよ。
"Have you tried out the restaurant down the road yet?"
