Сравнение в английском при помощи оборота as...as (такой же...как)
После первого "as" добавляем признак, после второго "as" - объект сравнения. И все! И не забываем про глагол "to be" =)))

Потренируемся на тексте песни Lenka Everything At Once - нет примера этого правила лучше! Включаем и поем!!!

As sly as a fox, as strong as an ox.
As fast as a hare, as brave as a bear.
As free as a bird, as neat as a word.
As quiet as a mouse, as big as a house.

All I wanna be, all I wanna be, oh.
All I wanna be is everything.

As mean as a wolf, as sharp as a tooth.
As deep as a bite, as dark as the night.
As sweet as a song, as right as a wrong.
As long as a road, as ugly as a toad.

As pretty as a picture hanging from a fixture.
Strong like a family, strong as I wanna be.
Bright as day, as light as play.
As hard as nails, as grand as a whale.

All I wanna be oh, all I wanna be, oh.
All I wanna be is everything.
Everything at once.
Everything at once, oh.
Everything at once.

As warm as the sun, as silly as fun.
As cool as a tree, as scary as the sea.
As hot as fire, cold as ice.
Sweet as sugar and everything nice.

As old as time, as straight as a line.
As royal as a queen, as buzzed as a bee.
Stealth as a tiger, smooth as a glider.
Pure as a melody, pure as I wanna be.

All I wanna be oh, all I wanna be, oh.
All I wanna be is everything.
Everything at once.
