LEARN THIS! Comparative structures

1 We usually use more / less and (the) most / (the) least to form comparative and superlative adverbs. However, we add -er and (the) -est to some adverbs.

You should drive more carefully.

He used to drive faster. Now I drive the fastest.

2 We can use the following structure to show that two things change together because they are connected:

The longer he lives, the crazier things get.

The harder I tried, the better my life became.

3 Comparatives often have a clause after than:

She’s more upbeat than she used to be.

He’s less unhappy than I imagined.

John swam further than he intended to.
