四年級如何用英語介紹樹木

I like pine best. There is a pine tree planted in the flower bed downstairs， 

which is like a tall pagoda， The branches of the pine tree are like a long crutch， 

and the leaves of the pine tree are like a sharp embroidery needle， 

which is very sharp. If you accidentally touch your hand， 

you will be hurt. Pine is very tenacious， no matter what time of the year， It always keeping green.
