““Ladies and gentlemen, the Captain has turned on the Fasten Seat Belt sign. If you haven’t already done so, please stow your carry-on luggage underneath the seat in front of you or in an overhead bin. Please take your seat and fasten your seat belt. And also make sure your seat back and folding trays are in their full upright position.“←从别的地方转过来的，希望对你有用。
