This document discusses comparisons using "as...as" and provides examples of its use. It can be used to compare two things as equal. The pattern is "as + adjective indicating quantity + noun + as". For countable nouns, use "as many" and "as few" and the noun may be omitted. For uncountable nouns, use "as much" or "as little" and the noun can be omitted. In the negative, "not" is used before the comparison, while "quiet" indicates a small difference and "nearly" a big difference. "Just as...as" means exactly. Examples are given for comparisons of quantity, age, food eaten, news heard, and success
