On, in, under, through, above, below,
These prepositions we all know.
They tell us where things are in space,
And how they relate to time and place.
On the table, in the box,
Underneath the chair with shocks.
Through the door and down the hall,
Above the clouds and past it all.
In the morning, on the night,
Under the stars and shining bright.
In the summer, under the sun,
Through the winter, on the run.
On the beach, in the sand,
Under the waves, a wonderland.
In the city, on the street,
Through the crowds, with weary feet.
Above the noise, below the sky,
In the mountains, up so high.
Under the trees, in the shade,
Through the fields, where cows have grazed.
On the whole, in the end,
Understood by every friend.
These simple words, so often used,
In language we are not confused.
在上面用on，在里面用in，下面用under，三个都能走。
1. 在英语中，描述空间位置时常用的介词有很多，但是in、on、under等几个比较常见。
2. 这些介词在不同容器、物体的表述时都有规范的使用方法，需要根据具体的场景和语境来决定使用哪个介词。
3. 顺口溜对于记忆这些常用介词有一定的帮助，但是在实际运用中还需要结合具体的语境和情境来判断使用哪一个介词更为恰当。
同时，除了这几个介词以外，在英语中还有许多其他的介词描述空间位置，需要耐心学习和掌握。
