To Build Castles In The Air
不切實際
Castles are usually enormous structures requiring strong foundations and the use of heavy construction materials such as stone.
城堡通常是一座巨型建筑,需要有堅實的地基,還會使用到沉重的建筑材料,例如石頭等。
If the foundations are not strong enough, the castle could collapse.
如果城堡的地基不夠牢固,很可能會坍塌。
The idea of building a castle in the air-with no foundation at all-is, of course, ridiculous.
在空中建一座城堡是沒有地基的。因此,“空中樓閣”當然是一個很荒謬的主意。
That is why this idiom is used to describe ideas that are not realistic, as if they are dreams or fantasies.
因此,我們可以使用這個成語形容那些不切實際的想法——只不過是夢想或幻想。
