fly off 与fly以及fly away的区别

【需要注意的是off不是介词，其后面是可以接介词with】

(VERB) 飞;飞行;飞翔 When something such as a bird, insect, or aircraft flies, it moves through the air.

The planes flew through the clouds... 

飞机穿越云层。

 The bird flew away. 

鸟儿飞走了。

fly off

I wish I could become a bird so that fly off from this “nest”

我很想变成一只鸟, 从这座“鸟巢”中飞出去

飞出; 飞跑，【有突然离开的意思】

The birds flew off at the firing of the gun.

一开枪鸟儿就飞走了.

fly off the handle

(informal) to suddenly become very angry 大发雷霆

【从以上例句中我们不能发现off不是介词（prep），fly off 构成一个词组，这个词组表达的意义与fly away 相近。后文中的fly away 后面接了介词to，fly away to the south，飞到南方去。前文中的例句，fly off from the nest 从鸟巢中飞出去。 fly away with you 和你远走高飞】

fly away    离开，飞离;

1. When winter comes, some birds will fly away to the south.

2. You must approach the bird very quietly or it will fly away.

【这个翻译不错，飞翔，飞翔，后面的振翅高飞。fly，fly， 以及fly away.】
