即将起飞英文

All passengers please note: the plane is about to take off, please turn off the mobile phone, fasten the safety belt.

The plane is taking off right now.

the plain is flying，please get ready。

说得太多了会让你晕的，如果是想直接表示在跑道上加速，马上离地的话，就说：The plane is flying into the sky，这样就准确多了

ready to take off

Ladies and gentlemen, attention, please. The plane is taking off. Please shut off your cell phones, and make sure that the safety belt is in place.

The plane is to take off.

The flight to some place is about to take off.

be +doing 要表示将来时态只有当do是位移动词时才行比比如come.leave 所以正在起飞是The plane is taking off .而The plane is on take off。当中on 是介词后接动词原型明显不对。
