As...As Comparison Exercises

You can also use as...as with adverbs: "He doesn't run as quickly as his sister." A softer, slightly old-fashioned alternative is so...as in negative sentences: "It isn't so cold as yesterday," though "not as...as" is far more common in modern English. To show something is almost equal, add modifiers: "nearly as good as," "almost as expensive as," or "just as important as." This structure appears regularly in Cambridge B1 Preliminary and B2 First examinations, where students must recognise that "not as...as" and comparatives express the same idea in different ways.
Quick Rule
as + adjective + as (equal) | not as + adjective + as (unequal)
- 1.This jacket is as warm as my winter coat. (equal comparison)
- 2.She isn't as confident as her brother. (unequal — less confident)
- 3.Is your new flat as big as the old one? (question form)
- 4.Nobody in the class is as fast as Maria. (emphasising superiority)
- 5.The exam wasn't as difficult as we expected. (easier than expected)
