Other than the comparative form, we can also use these comparison clauses to show
as + adj+ as => that two things are equal.
too + adj =>that something is excessive.
not + adj + enough => that something is sufficient (or insufficient).
We can also compare using: Like + noun or gerund.
Have a look at these examples:
–She is too slow to be a good skater.
–She isn’t fast enough to be a good skater.
–His hair is too short to be a hippy.
–Goths have a face as pale as chalk.
–These trousers aren’t baggy enough for you to skate.
–There was a terrible blizzard; it was like the end of the world (LIKE + NOUN)
–Getting money from him is like getting blood from a stone (LIKE + GERUND)
