两道英语是非题
fly across the sky 还是 fly through the sky
The plane is flying above the roofs of the sky 还是 The plane is flying over the roofs of the sky
那么请问飞机是用fly across the sky还是fly through the sky ‘
鸟儿是fly across the sky还是fly through the sky
回答这个立即给分，麻烦，

答案

1.用fly through the sky更好.
across一般表示“在物体表面横穿”或“横贯”；而through表示“穿透/穿过”.
此短语表示的意思是“飞越长空”,即“穿越”,所以用through更好.
2.用The plane is flying over the roofs of the sky.更好.
above只强调“在...上方；不低于...”,可能会有接触；而over强调“在...的正上方,无接触”,所以用over更好.
